What Are the Most Common HVAC Problems?

Coil Care
Coil Care is important to help your HVAC system run properly and efficiently. A coil is a main component of your HVAC System. There is a condenser coil and an evaporator coil. These coils are an integral part of the heat exchange that happens when cooling your air. These coils contain your refrigerant. Many older systems used Freon (R22) while more recent systems use Puron (R410a).
Damaged or Leaking Coil
A damaged or leaking coil is a serious concern. Often this is a result of improper or no coil care. Refrigerant continually recirculates through the coils and does not deplete unless there is a leak. Most people do not realize they have a leaking coil until quite a bit has leaked out. By then, often there are multiple leaks. Most of these leaks are not repairable.
A leaking coil may be repairable, but only under a few rare conditions. Depending on where the leak is, it might be repairable by soldering. There are products sold as do-it-yourself projects but these are not good fixes and can damage your system further.
Unfortunately, if there are leaks or damage to the coil, it will often need to be replaced. This is a very costly problem and can cost almost as much as a new unit. Those who opt for a coil replacement should be aware that just replacing the coil can create a mismatched system. When systems are first installed they are installed as paired systems. By replacing a major component only, the system is no longer paired. This can effect any warranty you might have.
For this reason most reputable air conditioning specialists will recommend replacing the system. It will cost a bit more, but the entire system will carry a full warranty. Air Doctor Heating and Air offers a 10 year warranty on Parts AND Labor for new system installations.
Coil Care and Cleaning
Since the coils are such an important, integral and expensive part of your HVAC system it is wise to provide proper coil care. It is very important to have your system maintained twice a year, in the Spring and Fall. Properly maintaining your system ensures that it is properly adjusted to perform at it’s best.
During this maintenance, the coils will be checked and the technician may recommend a coil cleaning. Keeping the coils clean helps them last. Debris and buildup can lead to pinholes and leaks. A chemical cleaning should be performed by your HVAC Specialist. This is a small additional charge, but can go a long way in making sure your system performs at it’s utmost efficiency for as long as possible.
In Conclusion
In conclusion, it is most important to keep your HVAC system properly maintained and serviced twice a year. Spring and fall maintenance by a certified HVAC technician will keep your warranties protected and keep your system running at it’s optimal performance. Having your coils professionally, chemically cleaned when advised by your technician will keep them lasting as long as possible.
