Choosing the Ideal Commercial Thermostat for Your Business

/in /by

Every organization invests substantial capital in heating, ventilation, and air conditioning (HVAC) infrastructure. To maximize that investment, each HVAC component needs to work in unison to operate at peak performance, and that requires having the ideal thermostat to monitor and control your facility’s indoor climate. Without the right thermostat, your HVAC system ends up running more than it has to, driving up energy costs and leading to premature equipment failure. 

In this post, we’ll explore the various options on the market today, so you can decide which one is best for your day-to-day operations.

Mechanical Thermostats

Mechanical thermostats offer the simplest approach to controlling an HVAC system. You set the preferred temperature on a mechanical dial, and the thermostat continuously monitors air temperature at that particular spot in your building. As temperatures fluctuate, the thermostat sends signals to your HVAC equipment, telling it when to start and stop. Since it’s the oldest option available, it’s generally the most affordable, but also the least efficient.

Non-Programmable Thermostats

Non-programmable thermostats essentially work just like a mechanical thermostat, but instead of adjusting the preferred temperature with a mechanical dial, you use a digital interface to establish a fixed temperature. That means if someone forgets to adjust the temperature before leaving for the night, your system ends up running more than it needs to.

Commercial Programmable Thermostats

Like a non-programmable thermostat, a programmable thermostat uses a digital interface for monitoring and controlling your facility’s desired temperature. While a non-programmable thermostat forces you to set a specific temperature and manually adjust that temperature throughout the day, a programmable thermostat automates that process, removing the element of human error. With a programmable thermostat, you set your system up to run on a specific schedule, so the ideal temperature is automatically adjusted depending on the time of day and the day of the week. That way, your system runs when it’s needed, while running less frequently when your building is unoccupied.

Commercial Wi-Fi Thermostats

A wireless (Wi-Fi) thermostat works like a programmable thermostat while also connecting your facility’s wireless network. With network connectivity, you’re able to adjust the temperature and operation of your HVAC system remotely, so you can optimize system performance no matter where you are.

Smart Thermostats

As the latest development in the commercial HVAC thermostat market, smart thermostats use artificial intelligence (AI) to continuously monitor building operations and usage in real-time. With this data, an intelligent thermostat automatically adjusts air temperatures without requiring human intervention. 

By linking with a variety of HVAC sensors throughout your building, smart thermostats can automatically adjust for factors like fluctuating room occupancy, thermal levels, humidity, and even carbon dioxide levels. At the same time, smart thermostats often employ capabilities like wireless connectivity and voice control. While your organization should expect to pay a higher up-front cost, this cost usually offsets itself in the energy savings it delivers.

Summer Maintenance for Your South Florida Commercial HVAC

/in /by

As summer temperatures reach scorching heights, you’ll want to keep your HVAC unit in working order. You can perform regular maintenance checks yourself, or you can partner with an HVAC company like Garrison Mechanical, which can perform preventive maintenance for you. Whichever way you choose to check on your air conditioning this summer, here are some HVAC maintenance tips you can follow:

Replace Your Air Filters

This is one of the most important rules of HVAC maintenance. Replacing your air filters monthly, or at least seasonally, will prevent dust from building up in them. Dirty air filters restrict airflow in your HVAC system. This means your unit or system will have to work harder to run properly, driving up your energy bills and increasing the risk of a breakdown. Changing the air filters is one of the most inexpensive ways to ensure your HVAC system runs efficiently during the summer.

Install a Programmable Thermostat

A programmable thermostat, such as NEST, can learn your building’s cooling patterns. Once it learns these patterns, the thermostat can increase your HVAC system’s energy efficiency by sending cool air through those patterns. This allows your air conditioner to work with the building to cool it off.

Check for AC Slime

AC slime is part condensate left over in the AC unit’s drip pan and part water that mixes with the condensate. Algae and fungus can grow in AC slime, which will eventually clog the unit’s drain line if it is allowed to grow. You can remove the slime yourself either by removing the drip pan from the AC unit (if the drip pan is removable) or emptying the water from the pan with a cup (if it is not), spraying the pan and the coils with coil cleaner, and wiping down the pan and the coils. Then you can place two condensate tablets in the drip pan and allow them to dissolve. These tablets prevent AC slime from forming. This quick step can help your HVAC unit run smoothly for the rest of the summer.

Keep the Air Moving

You can improve the airflow in your building by keeping as many doors open as possible. Closed doors prevent air from circulating between rooms, so opening the doors will improve circulation. Running ceiling fans will also help the cool air from your HVAC system circulating throughout the building, but remember to turn them off during off-hours. These tactics will keep the air moving without forcing your HVAC system to work too hard.

Insulate Your Building and Your Ducts

Insulating your building with white blinds in the windows can help reflect heat away from it. You should close the blinds on the west- and south-facing sides of your building during the day for maximum effectiveness. You should also insulate and seal your HVAC system’s ducts to prevent them from leaking, which could raise your energy bills. Overall, insulation keeps your building cool and helps your HVAC system run efficiently for long periods of time.

Why You Should Invest in HVAC Test and Balance

/in /by

If you’re installing a new commercial HVAC system, you may know you should have your new system tested, adjusted, and balanced. But what exactly is air balance? What will this testing and balancing process do for your system and your building? Here’s what to know about the process.

What Is Air Balance?

Air balance is how much air a heater or air conditioner brings in versus how much air it expels. If the heating and air conditioning system expels more air than it consumes, it has a negative air balance. This commonly occurs in old buildings and in buildings that have been repurposed for new industries or extended through new additions. If the system brings in more than it expels, it has a positive air balance. But if the system brings in and expels the same amount of air, it has a neutral air balance. You want your system to have a neutral air balance.

Potential Air Balance Problems

When the air in your HVAC system is improperly balanced, problems can arise. For instance, if your system has a negative air balance, as described above, it is taking in untreated air and distributing it throughout your building. This creates condensation, and that condensation will invite contaminants into the system. These contaminants could increase the risk of health and safety problems among your colleagues and employees. Improperly balanced air can also cause drafts and cold spots throughout your building, and those will decrease your workplace’s comfort level.

What Does the Test-and-Balance Process Look Like?

At Garrison Mechanical, we have our new installations tested and balanced by a third-party contractor. This contractor performs NEBB-certified tests on our HVAC equipment to check its air flows (or water flows, for chilled water systems). Then the contractor documents all of their findings and compares them against the system’s design plans. They also make any necessary adjustments to make sure the system runs properly and has appropriate air distribution.
It is important to understand that although we do not perform the test-and-balance procedures ourselves, we hire and pay the contractor to make the process simpler and easier for you. We do this because we know you want to focus on running your business, so we provide a test-and-balance solution that’s painless for you.

Benefits of Test and Balance

Performing test-and-balance procedures on your heating and cooling systems provides many benefits for your business and your commercial building. These benefits include:

  • Prolonged equipment life
  • Increased energy efficiency
  • Optimized system performance
  • Improved air quality
  • Increased workplace comfort

These benefits contribute to a healthy, harmonious work environment, and they are just some of the reasons you should consider investing in HVAC testing and balancing.

We Can Help With Your Testing and Balancing

If you are interested in having a commercial HVAC company install your new system and letting that company take care of the testing and balancing process, contact us today. We will work with a NEBB-certified third-party contractor to make sure your new system works properly. Though this isn’t a process we work on directly, we can oversee it so you have fewer appointments to schedule, which lets you get back to running your business.

Increasing Your Building’s Energy Efficiency With HVAC Sensors

/in , /by

Today, as businesses worry more about their environmental impact, energy efficiency is more important than ever. So how can you make your HVAC system more efficient? Yes, you can seal your heating and cooling ducts, change your air filter, and get a programmable thermostat. However, commercial HVAC sensor controls are a great investment if you want to make your commercial building more energy efficient.
HVAC sensors conserve energy by sensing the environment of a given room or space so you can make operational decisions about the heating, cooling, and ventilating in that space. This enables you to conserve energy based on what you learn from the sensors’ readings. When you’re more informed about how your building consumes energy, you can make smarter choices to help it become more energy efficient.

Types of HVAC Sensors

These are the three types of sensors we install in commercial buildings:
Occupancy Sensors – Occupancy sensors measure the number of people in a room to determine heating, ventilating, and air conditioning needs. These sensors are used to control an HVAC system automatically by measuring the room’s occupancy.
HVAC Temperature Sensors – Commercial temperature sensors use a room’s occupancy readings to control the temperature. This sensor measures a room’s temperature and either increases or decreases its heating, air conditioning, or ventilation.
Pressure Sensors – Pressure sensors are used in variable air volume systems and coolers. This type of sensor monitors rooms and checks for drops in pressure that may indicate the measured space needs maintenance.

Benefits of Using HVAC Sensors

Sensors are one of the HVAC applications that yield many benefits. By measuring the occupancy and temperature of a room and adjusting heating and air conditioning, occupancy and temperature sensors can help lower your energy bills and make your business more energy efficient. The measurements these sensors take allow your HVAC system to adjust immediately and raise or lower the air temperature so your business isn’t heating or cooling a given space more than it requires, which prevents your system from wasting energy. You can also use the data sensors provide to learn about a room’s air flow and air quality. Additionally, using sensors in your building can reduce wear and tear on your HVAC system because the sensors prevent the system from running harder than the building requires.

Trust South Florida’s HVAC Experts With Your Sensors

If you are interested in installing HVAC sensors in your building, contact us today. At Garrison Mechanical, we install sensors from companies including Honeywell and Siemens, and all of the manufacturers that we work with specialize in building automation systems or large energy management systems. We can install and work with the sensors in your building to make sure your South Florida business stays cool all year long.

Commercial HVAC Repair vs. Replacement

/8 Comments/in /by

Determining whether to repair an HVAC system or replace it with a new one is a common dilemma. Sometimes in the HVAC industry, customers feel a technician has pressured them into buying a new system because they presented no other options. Conversely, technicians sometimes find themselves repairing an ancient system many times because business owners don’t realize replacement is an option. It’s important to weigh the decision to repair or replace your commercial HVAC system and to make sure you consider the following factors:

Age of Your System

Most commercial HVAC systems have a lifespan of 15-20 years, so if your system’s age falls into that range, you may want to consider commercial HVAC replacement rather than repairs. Of course, your business’s repair budget should be taken into consideration as well, as should the way your heating and air conditioning currently operates. If you have a 16-year-old system that needs relatively inexpensive repairs every once in a while, you may opt to stick with repairs for now and wait a few more years before you have a new HVAC system installed.

Maintenance Costs

Take stock of how much time you or the commercial HVAC company you partner with spend on reactive maintenance, such as equipment repairs, versus preventative maintenance, such as routine maintenance checks. If you’re spending more time on reactive than preventative maintenance, it’s probably time to consider replacing your system.

Repair vs. Replacement Costs

When considering HVAC repair or replacement, you can remember a simple rule of thumb: If your repairs cost more than 50% of the cost of a new HVAC installation, you’re probably due for a replacement. Other repair vs. replacement calculations include getting a replacement if the repair costs more than $5,000, and whether the cost of your repair multiplied by your system’s age is higher than the cost of a new system. Whichever calculation you decide to use, following the numbers is definitely a solid basis for your decision.

Signs of Deterioration

Does your duct system leak often? Does your HVAC unit make a lot of noise when it runs, or do does it randomly shut off? Does the system suffer frequent breakdowns? These are just some of the signs that may tell you it’s time to replace your HVAC system. If you want to stick with repairs, your system may need them more frequently, and that may interrupt its operation and maintenance. This could interfere with the heating and cooling in your office, and in your facilities, which could affect your products as well as your employees and customers.

Consider System Upgrades

Before you invest in commissioning a new system, you should consider upgrading specific parts of your system that have problems. At Garrison Mechanical, we can replace your system with a new one, but we can also replace individual parts, which will save you time and money on repairs, and could help extend the lifespan of your current HVAC system. The parts we can replace include air handlers, evaporator and condenser coils, pumps, motors, fan coils, chillers, and cooling towers. Upgrades give you a third option so your repair or replace decision isn’t so limited.

Let Us Help You With Your Decision

When you partner with Garrison Mechanical, we do our best to meet your needs every step of the way, and that includes when you’re considering replacing your HVAC system. We can work with you to understand your business’s HVAC system, and we provide a wide range of services, including commercial HVAC installation and replacement.

Preparing Your South Florida HVAC System for Summer

/7 Comments/in /by

As temperatures rise and humidity thickens the air, it’s time to start preparing your HVAC system for summer. What steps should you take to do that? In this post, we’ll outline some tips you can add to your preventative maintenance checklist.

Change Out Air Filters

This is one of the most cost-effective steps you can take to prepare your cooling system for summer. Changing your air filters monthly, or at least at the beginning of every season, will prevent dust and dirty air from building up in your HVAC system, which will save you money on service fees and energy bills in the long run. Taking this HVAC preventive maintenance step will improve the building’s air quality and your system’s energy efficiency. Cleaning out the air filters also can reduce allergens, so you won’t have to suffer through allergic reactions all spring and summer.

Install a Programmable Thermostat

A programmable thermostat, such as Sensi or NEST, can learn your building’s cooling patterns and adjust your HVAC system accordingly. This means the thermostat will customize the way it runs so your HVAC system doesn’t waste energy trying to cool your building in a way that doesn’t fit.

Insulate and Seal Air Ducts

Checking your air ducts can become part of your annual maintenance, and it definitely should become part of your summer preparation maintenance. If your air ducts are leaking, that could be costing you extra in your energy bills and your cooling and heating system service costs. Sealing and insulating your air ducts will help your HVAC system run more efficiently over longer periods of time.

Schedule an Air Conditioning Maintenance Appointment

While you can take your own steps to keep your system working well, some tasks are best left to the professionals. Scheduling a maintenance visit will give you a chance to find out if your HVAC system has critical problems that need fixing before temperatures really soar. The maintenance appointment should include specific HVAC maintenance measures, such as inspecting machine parts and checking refrigerant levels.
This is the summer preparation step where your system would most benefit from an HVAC preventive maintenance program. At Garrison Mechanical, we perform monthly HVAC service checks as part of our HVAC preventive maintenance contracts. Regular maintenance keeps your HVAC system from developing preventable problems, which is why having a preventative maintenance plan in place is always a good idea. With a preventative maintenance agreement in place, you can have peace of mind knowing your system will be ready for summer and won’t experience any breakdowns when you need cool air the most.

5 Signs of Commercial HVAC Issues

/2 Comments/in /by

We’ve all become familiar with the sound of the thermostat clicking on, but what about those strange sounds and symptoms you may notice developing over time? When should you be concerned, and when is it time to call an HVAC contractor to address the problem? In this post, we’ll break down five of the most common commercial HVAC issues and how you can pinpoint them.

Rising Utility Bills

If you’ve noticed that your utility bills have been consistently rising even after adjusting for the time of year and climate, your HVAC infrastructure may be to blame. If your HVAC equipment requires more energy to run, there’s likely a deeper issue that’s causing it to run less efficiently. Fortunately, you probably won’t need to replace the whole system. Most often, a few energy efficiency upgrades can curb rising your utility bills, quickly delivering a full return on investment.

Your System Continuously Runs

If you’ve noticed that your HVAC system continues running throughout the day without pause, the load on your system is higher than it can handle. Your system is having to work around the clock to maintain a temperature that it either wasn’t built to handle or can no longer manage. A piece of critical equipment may be outdated or broken. Either way, if your system runs continuously to maintain the temperature you’ve set it at, it’s time to call a contractor to pinpoint the source of the problem.

Your System Trips the Breaker

If your heating and cooling systems consume so much power that it repeatedly trips the circuit breaker, you probably have a deeper electrical issue. An HVAC contractor can help you pinpoint the root of the problem while ensuring that electrical problems don’t lead to more critical system failures later on.

Noisier Operation

You’ve probably become so used to the sound of your HVAC system operating that it’s become background noise. If you notice any unusual noises like rattling, squeaking, grinding, or banging, your place of business is either haunted – in which case we can’t help you – or your HVAC system may require maintenance or repairs. Sounds like vents contracting and expanding in cold or warm weather, however, are no reason to be concerned unless they seem to be impacting the performance of your system.

Strange Smells

If you notice unusual smells emanating from air vents or your air handler unit, you’re likely dealing with an underlying issue like mold, moisture buildup, or a leak. Distinct smells like sulfur or rotten eggs may be signs of a gas issue. Either way, an experienced HVAC contractor can pinpoint the root of the problem and take corrective issue as quickly as possible. When it comes to your heating and air conditioning systems, unusual smells should never be ignored.
Proactively Address Potential Issues

If you want to proactively address potential issues before they turn into critical problems that require extensive repairs, contact the experts at Garrison Mechanical today. We’re here to help you with everything from the latest energy-saving upgrades and minimizing energy bills to pinpointing the root cause of that strange noise.

How to Handle your Commercial HVAC Emergency

/in , /by

We all like to think that emergencies only ever happen to others. Unfortunately, this mentality, as much as we wish it to be true, does nothing to prepare for the reality of a disaster. If you’ve ever needed emergency HVAC service at the height of summer or in the grips of winter, you understand the importance of preparation. As a business, commercial HVAC system downtime during extreme winter quickly leads to uncomfortable employees, disappointed customers, lost revenue, and missed opportunities.

That’s why it’s critical to develop a backup plan in the even to a critical HVAC failure. If it’s too late and you’re experiencing an emergency, here are some quick tips to get your system back up and running as quickly as possible. If, on the other hand, your organization wants to take a proactive approach to HVAC emergencies, here’s what you need to know.

Basic Troubleshooting

Before you call an HVAC contractor, there are some quick steps you can take to see if you can get your system back up and running on your own. If your HVAC infrastructure won’t turn on, first check your breakers to make sure power hasn’t been cut off. Simply restore power at first to see if that resolves the issue. If your system is repeatedly tripping the breaker, there’s likely a deeper underlying issue that needs correcting.

Other factors to check include thermostat issues, dirty air filters reducing airflow, or debris that’s congesting condensers. A quick check of these systems may solve the problem, saving you the expense of having to call an HVAC company. However, if none of these quick fixes get your HVAC running again, it’s time to get in touch with the professionals. While you may want to see if you can fix the equipment on your own, small issues quickly become major problems when you don’t understand the intricacies of your HVAC system.

Prioritize Preventive Maintenance

The most straightforward way to handle an emergency is to take steps to avoid one altogether. By taking a proactive approach to your HVAC system, you can avert disaster altogether. A proactive approach includes seasonal maintenance appointments, corrective repairs, and efficiency upgrades that keep your heating and cooling equipment operating at peak performance while maximizing the longevity of your HVAC investment.

At the same time, when you partner with an HVAC contractor to develop a proactive maintenance plan, your partner takes a personal approach to understanding the intricacies of your system while prioritizing your organization’s needs. That means in the event of an emergency your HVAC contractor will have you at the top of their list for handling emergency repairs.

During peak seasons, when other businesses are scrambling to find emergency service, you’ll know exactly who to call. At the same time, because they already understand how your HVAC equipment works, they’ll be able to more efficiently assess your system and pinpoint the root cause of the problem. That means your heating or cooling system will be back up and running sooner than you thought possible following an emergency.

Start a Partnership

If you’re interested in taking a more proactive approach to HVAC emergencies, contact the experts at Garrison Mechanical. We’ll take the time to understand your HVAC infrastructure, maximize energy efficiency, and make sure your organization stays covered in the event of an emergency. Plus, you’ll always know exactly who to call for all of your installation and service needs.

Spring Maintenance for Your South Florida Commercial HVAC

/in /by

Spring is in the air, and now’s the time to ensure that your air conditioning system is ready to handle the peak heat of summer. Not sure where to start? In this post, we’ll share three simple steps you can take today to ensure your HVAC systems are running at peak performance, saving your business time and money in the long run.

Replace Air Filters

How long has it been since you replaced your air filters? Depending on the load demand of your system, we recommend replacing air filters on a monthly basis. This approach is one of the simplest, most cost-effective ways to prevent inefficient or damaged equipment. At the very least, you should be changing your system filters at the beginning of each season. Dirty filters restrict airflow circulation and don’t filter air as effectively, quickly leading to system issues and a decreased lifespan. Plus, your team can replace air filters in a matter of minutes, instantly improving air quality and system performance for a minimal investment.

Perform an Energy Audit

Between the peak seasons of winter and summer when your HVAC infrastructure demands the most energy, spring offers an ideal time to perform an energy audit. Take the time to total up how much your current HVAC systems are costing you.

Chances are, you’re paying more than you’d like. If so, consider the possibility of upgrading your equipment and total up how much capital you’d be willing to invest in any upgrades. An energy efficiency upgrade can start saving you money right away while making the most of your existing equipment. From there, you can consult an HVAC contractor to see how much an upgrade could save you, potentially offsetting the cost of your upgrades in energy savings. By completing upgrades in the spring, you can be confident that your air conditioners are prepared to perform at peak efficiency, even during the intense summer heat.

Schedule an AC Maintenance Appointment

While there’s a lot you can do to maximize the value of your HVAC systems, there are some tasks that are better left to the professionals. Tuning your equipment up after the winter is one of those things. A springtime preventative maintenance program can reduce the risk of critical a system failure that results in downtime and revenue loss. By proactively upgrading equipment, checking refrigerant levels, inspecting parts, and calibrating your thermostat, an AC maintenance appointment can quickly get you prepared for the summer. After all, making the time for an hour-long maintenance appointment in the spring is a lot easier than having to deal with a day-long system repair at the height of summer.

Contact the South Florida HVAC Experts

Whether you’re ready to schedule that springtime HVAC maintenance appointment, or you need emergency service, contact the highly-trained heating and air conditioning experts at Garrison Mechanical today. Centrally located in Pembroke Pines, we’re here for all of your HVAC installation, service, and maintenance needs.

What You Need to Know About the R22 Phase Out

/in /by

The Environmental Protection Agency (EPA) is in the process of phasing out ozone-depleting substances (ODS) like R-22 refrigerant in the United States by 2020. HCFC-22, also known as R-22, is one of the more popular refrigerants on the market today. Even if your organization’s air conditioning system relies on R-22, you have a variety of options moving forward. Here’s what you can and can’t do when it comes to the R-22 refrigerant phase-out.

What You Can Do

If your existing infrastructure uses and already contains any R-22 refrigerant, you can continue using it without legal penalty. However, if your organization plans to keep running equipment with R-22, the EPA recommends planning out a way to repair or replace any leaking equipment so that you can recover and reuse any refrigerant. Since R-22 won’t be readily available for purchase, you will plan on storing recovered R-22 to service any of your own equipment. However, once you run out of R-22, do not count on being able to obtain more. Once 2020 arrives, you’ll need to start looking for a more sustainable R-22 replacement solution.

What You Can’t Do

If your organization is planning to expand your AC system now or in the near future, new R-22 cannot be used to increase cooling capacity. Upgraded and expanded systems are still considered new systems, so you have to use either reclaimed R-22 or an alternative refrigerant. If you’re planning on making extensive HVAC equipment upgrades, you should plan on finding a system replacement that does not depend on an R-22 supply.

What You Should Do

If you’d like to continue using R-22 for the time being, feel free to do so. Just be aware that the importation and production of R-22 will become illegal on January 1, 2020. You should be prepared for the price of after-market, new, and reclaimed to rise sharply as individuals and businesses are purchasing R-22 to sell after the phaseout.

If your business wants to expand or upgrade your HVAC infrastructure, plan out a budget ahead of time for the long-term expenses of your HVAC system after R-22 has been phased out. You’ll likely discover that a more sustainable infrastructure update will end up saving you in the long run, so you can spend more on the upgrade itself. That’s why we recommend your organization starts pursuing environmentally-friendly initiatives that don’t rely on R-22 today. That way, you can break away from R-22 dependence and be better prepared for the challenges of tomorrow.

Replacement Options

With a wide range of R-22 refrigerant alternatives already on the market, switching over to R-22 replacements couldn’t be easier. Many options are even more efficient than R-22, so you can save money on electricity and utility bills. On top of improving energy efficiency, these options do not deplete the earth’s ozone layer as R-22 does. As each day passes, there are fewer and fewer reasons to continue relying on R-22.

Alternative options include:

  • 404A, AZ-50 (507)
  • AZ-20 (410A)
  • 407C
  • 422D
