Room air conditioners, or window units, can be economical and beneficial for many homeowners. But if your room air conditioners can't keep up with the heat anymore, service the appliances soon. Your room AC could have one or more of the following issues.
Icy and Dirty Evaporator Coils
Room air conditioning units usually come packaged, or manufactured, with everything they need to keep homes cool, including an evaporator coil. Evaporator coils suck or extract heat directly from the air. However, tiny particles of debris can also enter the coil over time.
If the evaporator coil in one or all of your window units clogs up with dust, the fixture won't cool down your house in a timely manner. In most cases, the coils will become icy. An icy evaporator coil eventually stop extracting heat from the air.
If possible, take time to clean each unit's evaporator coil with vinegar or plain warm water. You can also use a soft feather duster, toothbrush, or air conditioning fin brush to clean the coils. Your window units may perform better after the cleaning. If your room unit don't improve after you clean them, call an AC technician right away.
Room air conditioning units also use blowers to cool down homes. If the blowers break down from stress or age, they can't push enough air toward the evaporator coils. Rooms further away from the window units may receive little to no air during the day.
A technician can check the blowers for age- or stress-related damage. If the blowers are dirty, a contractor can clean them. Blowers can pick up dust during the year and clog up.
If the blowers are beyond repair, a technician may suggest you replace your room air conditioners. You may also consider replacing your window units with mini-split units. Mini-spit units don't require air ducts, which means you can install them almost anywhere in your home.
Central air conditioning may also be an option for you. Central air units generally require air ducts to transport and transfer air through the home. The units may be packaged into one solid unit, or they may come in two separate units. A technician may have a list of central air conditioning systems you can look over during the visit.
