Building occupants only think of HVAC problems when it starts to affect their day to day lives. Employees call the facilities manager complaining about the air conditioning being too cold, and others feel the air is a bit stuffy. Tri-Tech Energy is familiar with all the HVAC issues commercial building managers face. We have, after all, been providing strategic heating, ventilation, and air conditioning solutions to NJ clients for more than thirty years!  That being said, there are a few common commercial HVAC problems affecting the year-round comfort of occupants. Let’s take a closer look at the main issues and offer solutions to help. 

Common Problems with HVAC Systems

HVAC common problems include dirty filters, malfunctioning thermostats, dirty condenser and evaporator coils, and mechanical issues. Air filters are essential to maintain high indoor air quality (IAQ) and work hard to keep dust, pollen, mold spores and other pollutants from circulating through a building. Building occupants are most sensitive to changes in temperature. A malfunctioning thermostat cannot sense indoor temperatures, and therefore cannot adapt the HVAC’s output to create a comfortable environment.  

Dirty condenser and evaporator coils are often the cause of HVAC problems as they reduce the system’s efficiency. All HVAC systems have mechanical parts such as belts and bearings, which suffer from wear and tear. These common problems are aggravated even further when regular maintenance is not performed. 

What Causes an HVAC to Freeze Up?   

Commercial air conditioning is a vital part of the HVAC system, but what causes an HVAC to freeze up? There might be several reasons that only become clear once the system is checked, but inefficient airflow, problematic drainage, and low refrigerant fluid levels all have an impact. Warm air must circulate into the air conditioning (AC) unit to keep the coils cold. Insufficient airflow causes the AC to freeze as the water cannot condense away. 

Water vapor condenses into liquid during the cooling process. When the liquid cannot drain away, the AC’s coils freeze. Air conditioners need the correct refrigerant fluid levels to function optimally. When the fluid is low, the AC’s coils become too cold and freezes.

How to Fix Common HVAC Issues  

Regular maintenance is the best way to prevent common HVAC issues from occurring. If your commercial HVAC system has dirty filters, have them cleaned by professionals and replaced if necessary. Does the thermostat run on batteries? Replacing the old batteries might resolve the malfunction. An expert can check the settings, clean the interior, and do the necessary recalibration if the thermostat continues to be problematic. 

Dirty condenser and evaporator coils must be cleaned by a professional service provider who can also inspect and clear drain lines and pans. Tri-Tech offers mechanical services that can help your company manage the normal wear and tear of HVAC systems. Our expert team knows how to fix an HVAC system for large apartment buildings, offices, colleges, hotels, and more.   

How Often Should HVAC Systems Be Serviced?  

Best practice includes a regular maintenance program that involves servicing twice annually, before each heating and cooling season. More regular maintenance might be required if the HVAC system is old, there is a change in the building’s use, or the area is experiencing prolonged abnormal weather patterns.

Tri-Tech is very knowledgeable about HVAC systems in older buildings. There is almost nothing we haven’t already seen, figured out and serviced in a timely, cost-effective way. We use advanced diagnostic equipment to locate the problem, no matter the system’s age, and evaluate the HVAC’s condition before we offer clients options and make recommendations. Clients choosing Tri-Tech for HVAC servicing receive a comprehensive “maintenance-plus” program, and technicians are onsite up to 4 times a year to perform maintenance.
