Are you questioning if your evaporator coils need to be cleaned during an HVAC maintenance service? If so, there are a few telltale signs that can help you decide if it's time for a cleaning. The most evident symptom of a dirty coil is that the air conditioner loses cooling capacity. You'll observe that the air isn't as cold as it should be. If this is the case, it's best to have the coils cleaned by an HVAC specialist.
Another indication of a dirty evaporator coil is frost buildup. This occurs when condensation forms on dirt and then freezes while the air conditioner is running. The frost prevents heat transfer with the air in the house, causing the air conditioner to stop cooling completely. Fortunately, scheduling air conditioner maintenance can be cost-effective and cheaper than a repair service.
Locating the coil can be difficult because it is usually located inside the air conditioning unit, so you should ask your trusted HVAC service professional to show you how to find it at your next appointment. Cleaning your evaporator coils is an important part of regular HVAC maintenance. If you notice any of these signs, it's time to call an HVAC professional for a cleaning service. Doing so will help ensure that your air conditioner runs efficiently and effectively all summer long.
