My Air Conditioner Won’t Turn On

Serving Vancouver WA | Clark County Washington

Outdoor air conditioner unit. Vanport Mechanical explains why your air conditioner might not be turning on.

Your air conditioner is one of those appliances you may not notice until it stops working. If your air conditioner won’t turn on, you may be able to fix it yourself. Below are some common reasons why your air conditioner won’t turn on and ways you can fix the problem.

Check to See If the Breaker Has Tripped

If your home air conditioner won’t turn on, the first thing you should check is the breaker. If the system comes on after resetting the breaker, and then trips again shortly after, this could be an electrical issue or a sign that your air conditioner’s compressor has failed. The licensed technicians at Vanport will be able to better determine the exact cause.

Does the Thermostat Have Power?

If the thermostat is not hard-wired it could be as simple as replacing batteries. It’s also possible your thermostat has failed. While most HVAC equipment has a 15-20 year life span, thermostats generally only last 5-7 years.

Are the Filters Clogged?

Clogged air filters cause airflow restrictions which can cause the AC unit to operate harder than it should. Check for dirty or clogged air filters. Also, make sure all the vents in your home are opened and cleared of any furniture blockages.

Is There a Drain Clog?

Many condensate drain pans are equipped with a float switch or wet switch. If the drain clogs and water backs up into the pan, the switch will trigger the air conditioner to shut off. The float switch is there to prevent water damage. These switches are most common when your air handler and evaporator are in an attic or finished space. At Vanport Mechanical, we’ll inspect your drain pans and check the rest of your system to make sure every component is properly tuned.

Maintenance Can Help Prevent AC Problems

Your air conditioner needs regular maintenance to run properly and efficiently. At Vanport Mechanical we recommend your system be serviced at least once a year. When you choose Vanport Mechanical for your seasonal or annual HVAC maintenance, you’ll enjoy several exclusive benefits.
