When to Replace or Repair Your AC Evaporator Coil: A Comprehensive Guide

It's a common rule of thumb in the industry that if your air conditioning unit is more than 8 years old, it may be more beneficial to replace the entire unit rather than just one. Your system's HVAC evaporator coils are vulnerable to various types of problems, such as cracking, freezing, and dirt buildup. To maintain the evaporator coils in your system, contact an authorized contractor for an annual air conditioner tune-up. While homeowners like you should be able to handle tasks such as air filter replacement, you'll need a certified technician to treat frozen or leaking evaporator coils.

From time to time, changing just one set of coils can pose other major problems. Therefore, it is better to replace the entire unit rather than just the evaporator coil. Generally speaking, replacing the AC coil is only a good idea if the SEER rating of the new coil is similar to the old one. That way, the system can adapt to the new SEER classification without issues.

The evaporator coil is an integral part of an air conditioner or heat pump that absorbs heat and moisture from the air in the house. In the case of an R-22 air conditioning system, you should consider a leak in the evaporator coil as a sign that you need to install a new, updated system. This is the industry standard design because most air conditioners process air vertically and blow it up or down above the coils.

Knowing when to replace or repair your air conditioner (AC) is a common problem faced by many homeowners. This comprehensive guide aims to help you decide if you should replace a damaged evaporator coil or the entire air conditioning unit. As hot air flows over the evaporator coil, heat from the air is transferred to the refrigerant, cooling and drying the air and heating the refrigerant. Unfortunately, dust, dirt, pollen, and other air pollutants that accumulate in the air filter can pass through the air filter and adhere to moisture from the evaporator coils.

The evaporator coil is a vital and expensive part of your air conditioner and must be repaired or replaced by a licensed HVAC technician. If the evaporator coil fails, your AC will no longer be able to cool the air that passes through it and the air that exits from the ventilation grilles will heat up. The main signs that your AC evaporator coils are in poor condition include cracking, freezing, and dirt buildup. If your system distributes hot air in your home, hire a certified technician to inspect your HVAC evaporator coils.
