Everything You Need to Know About the Most Common AC Problems

As a homeowner, dealing with air conditioning problems can be frustrating and overwhelming. At All Fresh Temp Heating & Air Conditioning, we understand the importance of a functioning AC system, especially during the hot summer months in San Jose, CA.

To help you stay cool and comfortable, we've compiled a list of the top 5 most common AC problems and how to fix them.

1. Dirty or Clogged Filters

One of the most common causes of AC problems is a dirty or clogged filter. A dirty filter can restrict airflow, causing your system to work harder and less efficiently. This can lead to increased energy bills and even damage to your AC unit.

To prevent this, it's essential to regularly clean or replace your filters. The U.S. Department of Energy recommends checking your filter every month and replacing it at least every three months.

2. Refrigerant Leaks

Refrigerant is the substance that cools the air in your AC system. If your AC is low on refrigerant or has a leak, it won't cool your home effectively.

Signs of a refrigerant leak include:

  • Ice buildup on the evaporator coil
  • Hissing noises
  • And decreased cooling performance

If you suspect a refrigerant leak, it's important to call a professional HVAC technician to assess and repair the issue. The Environmental Protection Agency (EPA) also requires proper handling and disposal of refrigerants due to their potential environmental impact.

3. Thermostat Issues

Thermostat issues can cause your AC to run inconsistently or not turn on at all. If your AC isn't working, first check to see if your thermostat is set to the correct temperature and mode.

If that doesn't resolve the issue, your thermostat may need to be recalibrated, replaced, or upgraded to a programmable or smart thermostat. According to the U.S. Department of Energy, upgrading to a programmable thermostat can save you up to 10% on your heating and cooling costs.

4. Drainage Problems

Your AC system has a condensate drain line that removes moisture from the air as it cools. Over time, this line can become clogged with dirt, algae, or other debris, causing water to back up and potentially damage your system.

To prevent drainage problems, regularly inspect and clean your condensate drain line. If you notice water pooling around your AC unit or signs of water damage, call a professional HVAC technician to assess and repair the issue.

5. Electrical Issues

Electrical issues can cause your AC system to malfunction or not turn on at all. Common electrical problems include blown fuses, tripped circuit breakers, and worn or damaged wiring.

If you suspect an electrical issue, it's important to call a professional HVAC technician to assess and repair the problem, as handling electrical components can be dangerous without the proper training and equipment.
