An HVAC coil is one of the key components of an HVAC system and is vital to the cooling process. We have repaired a variety of commercial HVAC coils and units for hospitals, schools, and a variety of businesses. From New York and New Jersey to Maryland and all over the East Coast we have seen HVAC coils that are damaged leaking and in dire need of repair. We want to help you determine the signs of a bad evaporator coil and how to fix your evaporator coil.
Signs Of A Bad or Broken Evaporator Coil In Your Commercial HVAC System
Below are the common signs or symptoms of a broken HVAC coil and the solutions to fix the HVAC coil issues.
- Air conditioning is warm or there are hot and cool spots.
- Cooling system is making banging noises.
- Air conditioning refuses to turn on.
- Fluids like oils or refrigerant are leaked in or around HVAC unit.
- Air conditioning runs frequently but does not seem to produce desired results.
1. Your Company’s Air Conditioning Is Not Working
This is the most obvious sign of an evaporator coil being damaged and not functioning, but it can be a range of reasons beyond even the HVAC coil being broken. Everything from your HVAC coil leaking fluids to it being damaged and inoperable
2. Your HVAC System & Coil Is Leaking
You can typically identify a coil leak by oil on the U-tube or pan or simply around the coil. A leaking coil needs to be fixed in order for it to become operable again. Another indicator for leaks from your HVAC system is water stains in ceiling tiles or, specifically, pooling water near the air handler.
Water and moisture buildup is one of the major problems with HVAC cooling and heating systems. It can lead to mold that needs to be removed, rust, and an HVAC system that does not function properly. Water can also be a key indicator of issues with your HVAC system. A poorly insulated air handler can lead to condensation build up, and that condensation will reveal itself in the diffusers in the ceiling.
3. HVAC Coil Become Fouled
Your HVAC Coil can build up with dirt and grime that keeps it from being operable. This grime can hold moisture around the coil leading to rust and degradation of the entire coil system. If your building is close to a highway sprayed with salt, it can get on your HVAC coils and lead to them rusting and deteriorating very quickly.
4. Frozen Evaporator Coil
A frozen evaporator coil is typically caused by weak airflow. Essentially the system is doing its job, but the air is not moving correctly through the unit. This can be caused by restricted airflow in the ductwork. Which means your ductwork needs to be cleaned in order for your HVAC system to work properly.
It can also be caused by dirt build up in other areas of the HVAC system. We often find the issue after we thaw the frozen evaporator coil.
5. Crimped Evaporator Coil
If the evaporator coil is damaged and crimped, it does not allow airflow through the system, and it will not effectively cool the air. Or it will cool the air that is present and cause the evaporator coil to freeze. Repair your evaporator coil with a fin comb to allow the coil to work effectively again.
Contact PROAC To Repair, Maintenance & Clean Your Evaporator Coil
Preventative maintenance on your evaporator coil and the entire heating and cooling system will lead to the longevity you desire from your HVAC system. An HVAC system for a hospital, school, or manufacturing facility is expensive to replace. Make sure yours is getting attention and regular maintenance so it can last longer. Contact PROAC for commercial HVAC cleaning services and HVAC maintenance or HVAC repair. We are located in Central Pennsylvania and serve a range of states on the East Coast.
