What Is the Most Common AC Repair?

April 4, 2025

Here’s What You Should Know

When summer heat rolls in, the last thing you want is your air conditioner acting up. Whether you’re in Salt Lake City, West Valley City, Sandy, South Jordan, Murray, or Draper, knowing what’s likely to go wrong can help you catch issues early and avoid breakdowns.

So—what is the most common AC repair? Let’s break it down and cover what you need to watch for.

The Most Common AC Repair: Low Refrigerant or Refrigerant Leaks

If your AC isn’t blowing cold air, there’s a good chance you’re dealing with low refrigerant. This issue is often due to a leak in the refrigerant lines, which can cause your system to lose cooling power or stop working altogether. Not only does it reduce efficiency, but it also puts strain on your system.

Over time, refrigerant leaks can damage your compressor, leading to far more costly repairs. This is one reason why professional AC inspections are essential—especially before peak summer use.

Other Frequent AC Repairs We Handle

While refrigerant issues top the list, here are several other common AC repairs that homeowners in Utah request:

  • Frozen evaporator coils: Often caused by dirty air filters or low refrigerant.
  • Dirty condenser coils: Located outside your home, these coils can get clogged with debris, leading to reduced cooling performance.
  • Faulty capacitors: These electrical components help your AC start and run. When they fail, your system might not turn on.
  • Thermostat problems: Whether it’s outdated or just malfunctioning, a bad thermostat can throw off your home’s comfort.
  • Drain line clogs: A clogged condensate line can cause water to back up into your system, risking water damage and shutdowns.

FAQs

What typically breaks on AC?

The most common parts that break on an air conditioner include the capacitor, contactor, blower motor, and refrigerant lines. Other frequent failures involve clogged drain lines, dirty condenser coils, and faulty thermostats. These issues often lead to your AC not cooling properly, making regular maintenance critical for homeowners in Salt Lake City and nearby areas.

What is the $5000 AC rule?

The “$5000 rule” is a general guideline to help homeowners decide whether to repair or replace their AC system. You multiply the age of your HVAC unit by the cost of the repair. If the total exceeds $5000, it’s usually more cost-effective to replace the system. For example, if your unit is 12 years old and the repair is $500, the total is $6000—suggesting it’s time for a replacement. Our team can help you evaluate this with a free AC replacement estimate.

What is the most expensive part to replace on an AC unit?

The compressor is usually the most expensive part to replace in a residential AC system. It’s the heart of your air conditioner and responsible for circulating refrigerant. If it fails, especially on an older unit, replacement can cost thousands of dollars—sometimes making it more affordable to install a new HVAC system altogether.

Does homeowners insurance cover AC breaking?

Typically, homeowners insurance does not cover AC breakdowns due to wear and tear or lack of maintenance. However, if your AC unit is damaged by a covered peril (like a fire, lightning, or vandalism), insurance may provide coverage. We always recommend checking your specific policy to understand what’s included and exploring a home warranty for additional protection.

What is the first thing to check when the AC goes out?

When your AC stops working, start with these basics:

  • Make sure your thermostat is set correctly
  • Check your circuit breaker
  • Inspect the air filter for clogs
  • See if the outdoor condenser unit is running

If everything seems normal and your AC still won’t cool, it’s time to call in the pros.
