Why Isn’t My Air Conditioner Working? Kaysville Homeowner’s Guide

When hot weather hits Kaysville, Utah, the last thing you want is an AC that won’t keep your home comfortable. The good news? Most air conditioner problems come from common causes that you can often check before scheduling service. At Golden Rule Plumbing, Heating & Cooling, we’ve helped Kaysville families keep their homes cool for years. Here are the top reasons your AC may not be working—and what you can do about it.


1. Thermostat Issues

If your thermostat isn’t functioning properly, your AC won’t turn on or cool.

  • Make sure it’s set to “Cool” mode and a temperature lower than the current room temp.
  • Replace batteries or reset it if the display is blank or unresponsive.

2. Dirty or Clogged Air Filter

Utah’s dust and seasonal pollen can clog filters fast.

  • Replace your filter every 1–3 months.
  • A dirty filter restricts airflow, freezes coils, and reduces efficiency.

3. Tripped Breaker or Blown Fuse

Sometimes the issue is electrical.

  • Check your breaker panel for a tripped “AC” or “HVAC” switch.
  • If it trips again after resetting, call a technician to inspect the system.

4. Outdoor Unit Blockages

Your condenser needs space to release heat.

  • Clear away leaves, grass, or debris within 2 feet of the unit.
  • Rinse the coils gently with a garden hose to improve airflow.

5. Frozen Evaporator Coils

Ice is a warning sign of airflow or refrigerant problems.

  • Common causes include dirty filters, blocked vents, or low refrigerant.
  • Shut the system off and let it thaw. If freezing continues, call a pro.

6. Clogged Condensate Drain Line

High summer humidity in Kaysville means more condensation.

  • A clogged drain line can shut down your system or cause leaks.
  • Try flushing it with vinegar or using a wet/dry vac. If water pools, call for service.

7. Low Refrigerant or Leaks

Refrigerant is critical for cooling your home.

  • Signs of low levels include weak cooling, frozen coils, or long cooling cycles.
  • Only licensed HVAC technicians can repair refrigerant leaks and recharge the system.

8. Faulty AC Components

If you hear buzzing, clicking, or the system won’t start, parts may be failing.

  • Capacitors, compressors, motors, or contactors are common culprits.
  • These high-voltage repairs should always be left to professionals.

9. Leaky Ducts or Poor Insulation

Cool air may be escaping before reaching your living spaces.

  • Leaky ducts or poor insulation waste energy and reduce comfort.
  • Sealing ducts and upgrading insulation can make your home more efficient.
