It is never a good sign when you turn on your air conditioner and warm or hot air is coming out instead of the cool air you were hoping for. There are a number of things that can go wrong in an air conditioner and a few of them can cause warm air to blow into your home. Ambient Heating & Air Conditioning will share what can cause warm air to flow into your home and what to do if this occurs.
Air Conditioner Blowing Warm or Hot Air?
Thermostat – Look for the simplest solution first by checking your home’s thermostat. Sometimes the thermostat is left in the “Heat” position or somehow got set to “Heat” by accident. While inspecting your thermostat also check to make sure that the secondary control is set to “Auto” and not “ON” if the thermostat fanning control is set to “ON” it will run continuously which can cause warm air to blow inside. Make sure the thermostat during summer is set to “Cool” and “Auto” for proper performance. If your thermostat controls are in the correct position then look for other possible causes.
Air Filters – If not the thermostat, then the next easiest thing to check is the air filters. If the air filters have been neglected and becomes clogged with dirt and debris, it will restrict the air flow. If the air filters do get neglected, manufactures claim it can cause warm air to blow. However a clogged air filter can also put a strain on the air conditioning unit and can damage some of the internal components which result in failures. If the air filters aren’t the cause of the warm air, it could be due to a broken component which may have broken down due to the strain. Air filters are super easy to change and should be done regularly to ensure your entire HVAC health.
Dirty Coils – The coils, especially the evaporator coils, are designed to control the occurring condensation that forms inside your air conditioner. If the coil gets dirty, which does happen over time, it can cause the air conditioner to freeze and build up ice on the coils, copper lines, and the condensate and or compression coils. First check for signs of ice around your air conditioner and coils. Have the coils cleaned and check for any possible obstruction to help correct the problem. If the air conditioner continues to blow warm air, then most likely an internal component isn’t functioning correctly.
Refrigerant Leaks – If the refrigerant lines have a leak and your air conditioner is either out or running low of refrigerant, this too will cause only warm air to blow. If this is the reason, it will require a licensed HVAC technician to refill the refrigerant and repair the leaks. There also could be electrical wiring issues or the compressor is broken and needs repair. All require an HVAC technician to come and repair these common problems.
