Why Won’t My Air Conditioner Turn On?

When it gets hot in Utah, it gets hot. And that’s no time for the air conditioner to quit working. There are several reasons why an AC system breaks down, but what do you do if it won’t turn on at all?

If your family has infants, seniors, or someone in treatment for chronic illness, no AC on a hot day can be a health risk. You need immediate assistance. Your local Mountain Home Services professionals can help.

Common Reasons Your AC Won’t Turn On

When your air conditioning unit fails to power up, there are several things to check:

  • Air filter: Even the most diligent homeowners can forget to change air filters. If your air filter is clogged with dust and airborne dirt, your HVAC unit can overheat and refuse to start.
  • Circuit breaker: Check this first. Your HVAC system probably has its own circuit, and if it’s tripped, reset it. If it trips again, call Mountain Home Services.
  • Thermostat: Make sure the thermostat is in the “cool” setting, and the temperature is set lower than the outdoor temperature. If you change the thermostat settings and don’t hear the click or the AC doesn’t come on, it may be a thermostat problem.

Tips For Troubleshooting Your Mini-Split

Ductless mini-split systems are terrific! They’re the perfect answer to thermostat wars, houses with additions, and too-hot/too-cold people living together. But these units are like most appliances: Things can go wrong. If your ductless unit won’t turn on, there may be an easy fix.

  • Are communications working? It could be the remote control or a loose connection.
  • Check the circuit breaker.
  • Make sure the settings are correct, and “cool” is selected.

Problems That Require Professional AC Repair

Serious problems need professional air conditioning repair in Northern Utah:

  • Condensate line: The drain pan and condensate hose are responsible for removing moisture from the system. If they clog, it can cause the system to back up. To protect itself, the system refuses to start.
  • Evaporator coils: Clean evaporator coils are critical to your AC system. Dirty or frozen evaporator coils prevent your system from operating efficiently. That means you not only need repair — you’ll also be paying higher monthly energy bills.
  • Internal components: Noises, smells, moisture pooling near the unit… These are indicators that there may be component damage. It could be a slipped belt or something much more serious. Don’t delay contacting Mountain Home Services.
  • Refrigerant: Your AC will continue to operate with a refrigerant leak. But eventually, the system will repeatedly freeze up or stop working. If your AC operates but blows warm air or you hear hissing noises from the unit, shut it down and call Mountain Home Services.

Northern Utah AC Maintenance

Your HVAC system is the most expensive home appliance you own. It makes sense to get as much life out of it as possible. You can avoid serious AC problems and prolong its life span with spring AC maintenance.

HVAC tune-ups (spring and fall) will minimize costly, stressful downtime and repairs. It’s the best investment you can make to save money.
