Why is My AC Blowing Warm Air?

If your AC is blowing warm air, there may be several causes why. Once identified, you have the power to take action and resolve your problem yourself or call in an expert HVAC technician for further assistance.

Your air conditioning unit may be blowing warm air due to a dirty or clogged air filter. This can negatively affect how well it operates and increase energy costs by forcing the system to work harder than necessary. To avoid this from occurring, buy a new filter regularly or have an experienced AC service technician replace it annually during their annual tune-up.

Another potential cause of warm air coming from your AC could be low refrigerant levels or a frozen evaporator coil. This is a serious issue that should only be handled by an experienced HVAC technician as refrigerant is highly flammable and should never be attempted by anyone but an authorized professional. Also, refrigerant helps cool homes but should never be handled by anyone other than trained personnel as it poses risks to both you and your family if not handled correctly.

Your evaporator coil is essential in the cooling process of your AC, so when it becomes iced up, your AC won’t work correctly and may result in warm air. To avoid this from occurring, make sure you clean your evaporator coils regularly by a qualified technician for optimal operation of your air conditioner.

If your evaporator coil is leaking or you have a failed compressor, this can be an urgent problem that should only be handled by qualified HVAC specialists. Refrigerant is a federally-regulated substance and should only be handled by experienced personnel.

Furthermore, never let anyone add more refrigerant without first fixing the leak if you want to avoid further issues in the future. Doing so could result in a larger repair bill and is something best left for professionals.

One of the most frustrating aspects of hot weather is not being able to cool your home sufficiently. Not only that, but a lack of air-conditioning can negatively impact your mood and productivity levels as well. There’s nothing quite like living in an uncomfortable house with an unresponsive thermostat when it’s scorching outside.

First and foremost, make sure the batteries in your thermostat are still operational. Otherwise, there could be a problem with the thermostat itself or that it has been set at a different temperature setting than what is necessary for optimal comfort in your home.

Next, inspect your breaker box to make sure your air conditioner is receiving enough power. If not, flip the breaker to “ON” and see if that makes a difference. If so, this could indicate an faulty breaker or fuse and should be addressed as soon as possible.

There are several other common reasons your air conditioning might blow warm air, so it’s essential to know what to look for and how to fix the issue. Most of these issues are easily fixable but if none of the above-mentioned solutions solve your issue, call in the pros – The Christianson’s team can diagnose what’s causing your home’s heating and cooling issues and provide a lasting solution.
