Once the summer months draw nearer, our air conditioners once again become the devices we rely on to keep us nice and cool during the hot weather. But what happens when your AC keeps blowing warm air instead of cooling down your home? What do you do when your trusted air conditioner no longer fulfills its primary purpose?

The best way to ensure the proper performance of your AC unit is to have reliable experts for air conditioning repair in Murrieta, CA at your beck and call. This way, you won’t have to worry about unexpected breakdowns and faults just before the summer season.

In this article, air conditioning experts tackle one of the most common HVAC issues – blowing hot instead of cool air. There’s no denying that hot air coming from your AC unit is not only inconvenient but it’s also extremely frustrating, especially during the summer months. Read on to find out why that happens and what you can do to fix the problem.

Why air conditioners experience cooling issues

There are numerous reasons why your air conditioner may be experiencing performance problems, from old age and lack of maintenance to refrigerant leaks and compressor problems. In many situations, it’s not entirely clear what the exact culprit is. That’s why it’s always better to rely on professionals to inspect your unit unless you wish to risk more severe issues down the line.

While reaching to professionals is nearly always advisable, it is possible that your air conditioner is not blowing cold air because you haven’t set the thermostat correctly. If that’s the case, you will be able to enjoy your fresh and cool home in no time, as all you’ll have to do is switch the setting from “heat” to “cool”.

What is wrong when an air conditioner blows hot air?

If you’ve determined that the thermostat setting isn’t the culprit, you will have to dig a little bit deeper. While your AC blowing warm air may not necessarily indicate a severe problem, it is definitely better to tackle the issue promptly to avoid any complications. Here’s what typically causes an air conditioner to blow out hot air:

General lack of maintenance

Just like any other device, your air conditioner needs to be regularly serviced and maintained in order to work optimally. Unless you make the effort to have your AC unit inspected, you will be very likely to experience occasional faults and malfunctions.

Many HVAC companies offer annual tune-ups and maintenance checkups that include everything your unit may need to stay in top shape for as long as possible. If you want to make sure your air conditioner is optimally efficient, investing in recurring HVAC maintenance is the only surefire way to achieve that.

Dirty air filters

If you want to ensure the proper performance of your air conditioner, you need to replace your air filters at least once every three months. The filter is designed to protect the interior components of your air conditioner from dirt, dust, and debris and maximize its lifespan. If you live in a warmer climate, you should check and replace your filters even more frequently, preferably once a month.

Clogged or dirty outdoor unit

Similarly, your condenser unit also requires regular cleaning and maintenance. While you can remove any visible debris that may be blocking the outdoor unit or interfering with its moving parts on your own, it is definitely better to have experts inspect and clean it as part of your general maintenance plan.

Refrigerant leaks

Refrigerant may also be the reason why your AC is blowing warm air. If you suspect that this may be the case, reach out to professionals immediately. Refrigerant, or freon, can’t get used up, and the only way for this to happen is if there is a leak. As inhaling refrigerant can be extremely dangerous, make sure to contact HVAC experts as soon as possible.

How do I fix my AC blowing warm air?

Just as there are different culprits for blowing hot air, there are also several different solutions that may help you get your unit back into shape. As we’ve already mentioned, you should always check the thermostat first to make sure that the settings are correct. If not, try:

  • Cleaning dust, dirt, & debris from your unit and replacing the air filter if needed
  • Checking out the air ducts and to look for leaks
  • Checking the circuit breaker box and fixing any blown fuses
  • Removing any branches, leaves, or other debris that may be blocking the condenser

If none of the above-mentioned tips work, your best course of action would be to call the professionals. What’s more, relying on HVAC experts for maintenance and service throughout the year is the best way to prevent such issues from happening in the first place.

Blowing warm air is only one of the numerous warning signs that may indicate that your air conditioner may need repair. Unless you don’t mind risking more severe problems and expensive repairs, make sure to act promptly as soon as you start suspecting that something might be wrong with your unit.
