One of the perks of having an air conditioner is enjoying a perfectly climate-controlled home, especially during the dog days of summer. But when you wake up in a pool of sweat wondering, “Why is my AC blowing hot air,” something is clearly amiss with your air conditioner.
Fortunately, Bill Howe can help. Before you panic, take a cold shower and let’s discuss why your AC may blow hot air instead of cooling your home and how to prevent it from becoming a common problem.
Common Causes of an AC Blowing Hot Air
An AC blowing hot air in the summer is never fun to deal with. Finding the answer is a process of elimination. There could be electrical problems, compressor problems, clogging issues, and more. The following are some of the top reasons your air conditioning system may have stopped cooling your home.
Thermostat Issues
Did you accidentally set the thermostat to supply warm rather than cool air? It happens, so make sure to double-check the thermostat settings. Many thermostats run on batteries, and when they’re dead, they won’t function. Of course, if all else fails, have a technician inspect your thermostat. It may be faulty and needs to be replaced.
Refrigerant Leaks
Look for hints of refrigerant leaks, such as your AC unit blowing hot air, high-pitched shrieking noises, and a higher-than-normal electric bill. Corrosion, clogged air filters, or improper installation can cause refrigerant leaks. If you suspect one, be sure to leave the repair work to a technician who knows what to look for and how to fix it right the first time.
Dirty Air Filters
Dirty filters can affect the performance of your AC, so it’s a good idea to replace them every 90 days. You can do this yourself. Just be sure to turn the AC unit off first. Then, open the vent, remove the old filter, install a new one, and close the vent!
Blocked or Dirty Condenser Coils
The condenser coils release the indoor heat they’ve absorbed. If your air conditioner is blowing hot air or your home smells musty, the coils may be dirty. Fortunately, they can be cleaned with a solution of water and mild household detergent.
Electrical Issues
Tripped circuit breakers can cause your AC unit to quit working, so be sure to open and look inside the circuit box. Faulty wiring can also lead to electrical issues, especially if the AC was installed incorrectly. Lastly, when it comes to electrical problems, stay safe and leave the hazardous electrical work to a professional technician.
Compressor Problems
The compressor plays a significant role in the cooling cycle—it compresses and pumps refrigerant so that your home is cool and comfy. Debris buildup leads to dirty coils, and if the compressor is no longer turning on, it’s a tell-tale sign that it needs repair or replacement. Call a professional. If the repair costs are minimal, have it repaired.
Clogged Drain Lines
The drain lines in an AC system are essential. After all, the drain lines remove all the condensation created during the cooling process. However, the lines can get clogged. The drains may be clogged if you notice water puddles, mold, or musty smells or if the air conditioner is blowing hot air. You can clear the drain line yourself by using a shop vacuum to remove blockages and then using a hose to flush it out. However, the best and easiest way to clear clogged drain lines is to call a professional.
Ductwork Issues
Another reason why your AC is blowing hot air could be leaks or disconnections in the ductwork. Poor insulation is another leading cause. Have the ductwork inspected by a professional. A certified technician knows what to look for and will fix it if ductwork repair or replacement is required.
DIY Troubleshooting Tips
Look out for telltale signs, like refrigerant leaks, and ensure the thermostat is in the right setting. You should also keep the area around the AC unit clear and free of debris. Changing the air filters is another simple remedy you can do to keep the cold air flowing freely. Of course, an HVAC unit is delicate and complex, so if you’re tired of scratching your head and asking, “Why is my AC blowing hot air in my house?” Call an expert!
