Is It Hot In Here? Common Commercial HVAC Problems and How to Fix Them

There are approximately 27.9 million small businesses currently in operation each year. And each one relies on their commercial HVAC system to keep the building comfortable.

When you start to notice HVAC problems, you can expect higher utility costs and less temperature control throughout your building.

The last thing you want to do is make the space uncomfortable for both your customers and employees. But how can you tell when it’s time to call a professional?

Here are a few of the most common commercial HVAC issues and what you should do to fix the problem once and for all.

Dirty Filters

Your commercial HVAC system, just like the one at your house, uses air from outside to keep your building comfortable. This means any dirt, debris, and allergens in the air make their way into the building.

The air filters in your commercial HVAC system collect most of the contaminants. This helps keep the indoor air quality as high as possible.

But over time, those filters start to get dirty. The dirtier they get, the harder your HVAC system has to work to keep your building at a good temperature. This puts extra strain on the system and can lead to extensive repairs down the road.

The best way to prevent this HVAC problem is to check your filters once every three months. When they look dirty, replace them.

Poor Air Flow in Some Areas

The dirt that your filters don’t catch gets stuck inside the ductwork. Over time, this keeps the fans from sending air where it needs to go when the system turns on.

You’ll notice this as low air flow in certain parts of the building.

The best way to keep the problem at bay is to schedule routine ductwork cleanings. Once you have the clogs removed, you’ll see an improvement in airflow and more consistent heating and cooling in your building.

Lack of Maintenance

The worst thing you can do for a commercial HVAC system is to neglect routine maintenance.

The larger your building is, the harder it is to heat and cool. This means your system will kick on more often. And the more often it turns on, the more wear and tear it experiences.

Every HVAC system needs routine maintenance and service. Try to schedule an appointment at least twice a year. This will keep most major problems from happening and can reduce your repair costs when the weather is extreme.

Strange Noises When Running

Often, your heating and cooling system will tell you when something’s wrong. If you hear strange noises coming from the system, pay attention.

It’s a sure-fire sign of HVAC problems.

If you hear noises, schedule a repair appointment immediately. The sooner you have the system inspected, the less long-term damage the problem can do to your system.

Blocked Air Vents

Believe it or not, one of the biggest problems business owners have with their HVAC systems is one that’s completely preventable. It’s a blocked air vent.

If a room isn’t reaching your ideal temperature, take a look around. Is a piece of furniture blocking the airflow? Did a trash can get moved on top of a floor vent?

Chances are, it’s a problem that’s easy to fix on your own. But if you can’t find the source of the blockage, schedule an appointment. The clog could be somewhere behind the register and it’s best to let a pro handle the cleaning.

Varying Temperatures

The average thermostat lasts for about 35 years. But that doesn’t mean they won’t become outdated sooner.

In fact, if you’ve recently installed a new heating or air conditioning system, you’ll start to see issues with your old thermostat.

If the system isn’t keeping your space at the temperature set on the thermostat, you probably need to upgrade. Schedule an appointment with your technician and let them inspect your thermostats. If they’re outdated, the problem should go away once you upgrade.

Oversized System

Believe it or not, some commercial HVAC systems are more powerful than they need to be. And this can result in an overly humid building.

Excess humidity leads to mildew and mold growth and puts your building at risk for water damage.

The easiest way to tell if your system is overly large is to watch your energy bills. Oversized units will have to turn on more often to heat or cool your building. This results in an increase in your energy bills each month.

If the increase is out of the ordinary, schedule an appointment with your technician. They’ll inspect your system and see if it’s the appropriate size for the building.

Outdated HVAC Units

Old units are far more likely to develop problems and repair issues. And the average lifespan of a commercial HVAC system is only about 15 years.

If you don’t know when the unit was installed or can’t remember the last time you replaced the system, it’s probably due for an upgrade.

Book an estimate with your HVAC repair expert and let them inspect the unit. If it’s outdated, they’ll help you find the right replacement for your building.

Dirty or Damaged Coils

Dirt and dust buildup on the condenser coils make your system run less efficiently. This means your building won’t heat or cool to the desired temperature easily.

The best way to prevent the problem in the first place is to schedule routine maintenance appointments. The technician will clean the condenser coils during each session. If they look worn or damaged, they’ll replace them before the coils start to cause major problems.

Low Refrigerant Levels

Commercial HVAC systems rely on refrigerant to cool the air in the building. If the system’s refrigerant levels are low or it’s actively leaking, you’ll start to see a decrease in the efficiency of the unit.

If left unaddressed, your system will experience excessive wear and tear that can lead to more severe repairs later on.

The sooner you schedule an inspection, the sooner the leak can get fixed. This will help you save money and keep your system running more efficiently for years to come.
