When summer kicks into high gear, staying cool becomes a top priority. However, many homeowners have trouble when their air conditioners start blowing out room-temperature or lukewarm air. If your air conditioner has this issue, one of the problems below is most likely the reason.
WHY IS MY AIR CONDITIONER BLOWING OUT WARM AIR?
It has a clogged air filter.
Experts recommend replacing basic AC filters every 1 to 3 months. A clogged filter can block airflow into your system, resulting in weak performance. This issue will also cause the AC to work much harder than usual, leading to lower efficiency and higher energy bills. Over time, the extra wear and tear can also dramatically shorten your system’s life.
The thermostat’s settings are incorrect or malfunctioning.
When your AC fails to produce cold air, first check the thermostat. Someone in your household may have switched it to “on” instead of “auto.” When your setting is “auto,” the fan will run only when your system is cooling or heating air. When your setting is “on,” the fan will run continuously, even when your AC is not conditioning air. If your thermostat is not responding, it may need new batteries, a repair, or a replacement.
Your system has leaky air ducts.
Leaky air ducts make it difficult for the AC to cool your home effectively. Rodents are infamous for chewing through ductwork. However, old age can also cause ducts to deteriorate and form gaps. Contact an HVAC expert to inspect your ductwork for leaks and provide professional duct sealing.
Your air conditioner’s coils are dirty.
Your outdoor unit’s condenser coil needs to be cleaned at least once a year. Dust and grime can cling to the coil, making it less effective at releasing heat from inside your home. Your indoor unit’s evaporator coil can also become caked with dust, inhibiting its ability to absorb heat from your home’s air. Schedule routine maintenance annually for your air conditioner to prevent this issue and many others. During the appointment, the technician will clean the coils, lubricate the engine, tighten loose components, and check for anything that might lead to a system failure.
Your air conditioner is low on refrigerant.
If your AC happens to develop a refrigerant leak (or if it was installed with too little refrigerant originally), it’s only a matter of time before you notice performance issues on scorching days. For a long-term fix, don’t “top off” your refrigerant! Instead, hire a licensed, certified HVAC professional to find the leak, repair it, and correctly charge your system with refrigerant. Otherwise, the problem will return.
