Air Conditioning Troubleshooting Guide: 10 Things That Can Go Wrong With Your A/C

A well-maintained air conditioner offers smooth, reliable performance when you need it most. Yearly preventive maintenance helps ensure your home stays cool, even in July, but you should also keep an eye out for common issues that, left untreated, may result in major repairs or even a complete replacement of your AC unit. If there are any items on this list that you are concerned may be affecting your home’s AC, the experts at Isley’s are always happy to help!

1. Dirty Air Filter

A dirty air filter drags down the efficiency of your entire HVAC system, raising your utility costs and shortening the life of your air conditioner.

One of the easiest things you can do to maintain your air conditioner is replace your air filter regularly (or clean, if you use a washable air filter). The ideal schedule in Arizona is monthly replacement between May and October and every other month from November through April. For people who live in milder climates, replacing or cleaning your air filter quarterly is adequate.

2. Refrigerant Leak

Just as in your vehicle, the refrigerant is how your air conditioner cools the air. When your unit develops even a small leak, the system is less efficient and fails to cool your home effectively. Your yearly maintenance call should include checking the refrigerant, replacing lost coolant, and addressing leaks.

3. Malfunctioning Thermostat

One of the first things to look at when your AC unit begins acting up is the thermostat, since it may cause the unit to stop working properly. It can be something as simple as a dead battery or something a bit more involved, such as faulty wiring.

4. Dripping Water

Air conditioners form condensation during normal operation, which is then removed by the condensate pump. If your AC unit leaks water, you may have a clogged drain pipe or faulty condensate pump.

5. It Makes Loud or Strange Noises

If your unit runs loudly or makes banging, popping, or creaking sounds, it’s time to call in a repair. Squeaking sounds indicate a belt issue, pops and cracks tell you there’s likely an issue in your ductwork, and grinding noises indicate a problem with the motor.

6. Air Conditioner Doesn’t Start

If your AC unit won’t start, first check that the thermostat is set to the correct temperature and is on “cool” mode. If it still won’t start, you may need to replace the battery, since a dead battery keeps your AC from running. Finally, check the circuit breaker to make sure you don’t have a blown fuse. If you try all of these things and the unit still won’t start, it’s time to schedule a repair.

7. The AC Doesn’t Stop Running

Your thermostat doesn’t just tell the AC when to start running; it also tells it when to stop. As always, first check the thermostat’s settings. There may also be an electrical problem with the outdoor unit. Your AC repair tech is your best bet to diagnose the cause.

8. The AC Unit Constantly Switches On and Off

Commonly referred to as short cycling, your unit may turn on and off frequently when the condenser coils get dirty, you have a refrigerant leak, or the air filter needs to be replaced. It may also happen when the unit overheats for other reasons, such as obstructions surrounding the outer unit.

9. The Unit Doesn’t Cool

Common reasons the air conditioner fails to cool include leaking ducts, that it’s time to replace the refrigerant, your air filter is too dirty, a malfunctioning compressor, and a blockage within the exterior unit. An experienced AC tech can diagnose the problem.

10. Your Power Bill Shot Up

One of the first signs there’s an issue with your air conditioner is a sharp spike in your power bill. Of course, your power bill rises every year when you first begin running your AC regularly, but look at the bill in comparison to the previous year. We’ve seen clients whose bills doubled compared to the previous summer – a sure sign there’s something wrong with the unit.

Rising power bills may also indicate leaking ductwork or a blockage within your ducts. You can also try changing out your air filter, particularly if you haven’t changed it in a while.

Arizona Cooling Costs By The Numbers

The United States Energy Information Administration (EIA) performs independent statistics and analysis of energy usage throughout the U.S. The following data points on Arizona’s energy consumption come directly from the EIA’s report, Household Energy Use in Arizona.

  • 25% of Arizona’s energy consumption goes toward air conditioning, which is more than four times the national average of 6%
  • 90% of Arizona households use air conditioning, with 86% of homes relying on central air for their cooling needs
  • Arizona’s energy usage for home cooling is 4 times the national average.
  • Air-conditioners use 5% of electricity produced in the United States.
  • Arizonans consume around 66 million Btu per home, which is 26% lower than the national average, but their energy costs are only 3% lower than the national average due to higher costs per kilowatt-hour
  • A/C units release about 100 million tons of carbon dioxide into the air every year.

One of the reasons Arizonans use less electricity as a whole is that their homes are relatively newer, as around half of all Arizona homes were built after 1990 compared to the US average of around 25%. They’re also more likely to have a programmable thermostat – 50% compared to under 40% across the US. Both of these items help save you money on your power bills.
