Why is My Air Conditioner Blowing Warm Air?

If your air conditioner is blowing warm air, there could be several reasons why. To avoid losing money in the long run, it’s better to reach the bottom of the issue as soon as possible.

7 Reasons Your Air Conditioner Could be Blowing Warm Air

Air conditioners slow down for a number of reasons, but common air conditioner issues resulting in warm air include the following.

1. Outdated System

The older and more outdated a system is, the harder it will be for it to accomplish its purpose. If your air conditioner is blowing warm air, the first question you should ask is, “How old is my system?” If you’ve had the system for more than 15 or 20 years, you should probably talk to a professional about replacement options.

2. Old Air Filter

If your air conditioner is still relatively new and in good shape, the problem may be as small as an old air filter. To ensure maximum air conditioner performance, you should change your air filters every few months, or as often as advertised on the filter’s packaging. Additionally, try your best to use high-quality air filters.

3. Lack of Maintenance

Ideally, you should schedule HVAC system inspections every year or two. Regular tune-ups protect you from unexpected repair costs and tend to save you money in the long run.

4. Low Refrigerant Levels

Refrigerant is the liquid that cools the moisture in the air before circulating it through your home. Not only does low refrigerant prevent your air conditioner from blowing cool air, it also threatens long-term damage to your air conditioner’s compressor.

5. Blocked Duct

Check all of your vents to ensure that they are open. Even if they are, a blocked duct might be preventing cool air from reaching your vents.

6. Faulty Thermostat

Since your thermostat is responsible for signaling your air conditioner to reach a certain temperature, warm air could indicate a faulty thermostat. First, make sure that the thermostat is on the right setting. If it is, but your air conditioner is still blowing warm air, ask a professional if your thermostat is causing the issue.

7. Electrical Failure

The issue could also be as simple as an electricity problem. A failed connection prevents your air conditioner from properly functioning, resulting in warm air.

How Can You Increase the Lifespan of Your Air Conditioner?

The best way to keep your air conditioner cool and efficient is to take good care of it. Taking proper care of your air conditioner also increases its lifespan, saving you money on constant repairs. Increase your air conditioner’s lifespan in the following 3 ways.

1. Maintain your HVAC system.

Schedule professional inspections annually. Air conditioner tune-ups prevent small problems from growing and can save you a lot of money.

2. Change your air filters regularly.

Not only does your air filter keep your air conditioner running efficiently, it also improves your indoor air quality by blocking allergens and pollutants. Better indoor air quality means better health.

3. Only run the system when necessary.

To increase the lifespan of your air conditioner, you have to maintain a balance between “too much work” and “not enough work.” If you let too much time rest between runnings, or your air conditioner constantly kicks on and off, it is more liable to break down. Be consistent, but don’t run it unnecessarily.
