How to Watch Out for Common HVAC Building Maintenance Problems
The best way to avoid HVAC building maintenance problems is to schedule a seasonal inspection and tune-up. This type of routine service will help keep your commercial system running efficiently all year round. It will also allow the HVAC technician to identify problems earlier, which will make it easier to conduct repairs. It’s also important to keep aware of developing problems. Here are a few common commercial HVAC issues to look for throughout the year.
Short or Repetitive Cycles
When your HVAC system functions normally, the compressor will cycle until the thermostat reaches a predetermined temperature. If you notice that the system continues cycling for long periods or starts and stops frequently, it’s wasting energy and causing greater stress to the overall system.
The problem may be as simple as a faulty thermostat. However, there may be other HVAC building maintenance problems causing this issue. Your HVAC contractor will check the refrigerant levels, air filters, and other problems that could be the underlying cause.
Refrigerant Leaks
In addition to speeding up the cycle time, a refrigerant leak can cause more extensive damage to your cooling system. Look for leaks around the base of your compressors. Additional signs of leaking can be found around valves, service ports, and other connections.
If left unaddressed, a refrigerant leak can cause the evaporator coils to freeze. This could lead your system to stop producing cool air or stop functioning altogether. Make sure you call for service as soon as you suspect a leak.
Dirty Air Filters
Your HVAC system’s air filters should be changed at least four times per year, although most commercial systems require monthly air filter changes. This is because a dirty air filter won’t allow air to pass through the system properly. Instead, the air is suctioned through any negative space that exists, bypassing the air filter altogether.
As air passes through the system in this way, it isn’t properly cleaned. The dirt in the air passes through and clings to the evaporator coils. As the coils become clogged, the debris builds up and inhibits operation. As a result, the system has to work harder to cool your building, shortening the lifetime of your system.
Dirty Condenser Coils
The condenser coils are located in the exterior compressor part of your cooling system, but they can still cause HVAC building maintenance problems anywhere.
These coils are responsible for transferring heat from the compressor out to the environment. As they accumulate debris such as leaves, animal fur, and litter, the condenser coils will lose efficiency. Lower efficiency means the system will operate at warmer temperatures, and it will be more challenging to keep your building cool. Fortunately, a seasonal inspection will include cleaning the condenser coils to prevent this issue.
Unusual Noises
One of the easiest ways to tell that your commercial HVAC system is failing is to listen for unusual sounds. If you hear a loud, rattling sound, there’s a good chance that the bearings in your blower motors need lubrication. Likewise, squealing noises suggest that the blower fan’s belt needs an adjustment or replacement.
Each sound your system makes represents a different cooling problem. The best way to diagnose the issue is to call your HVAC contractor. The help of professionals will save you time and money. You’ll also provide a cooler space for your employees and customers.
