Troubleshooting 3 Common Air Conditioning Issues

Most air conditioners have a lifespan of about 15-20 years, after which they no longer perform efficiently or at all. But even before an air conditioning unit starts nearing the end of its functional life, it can develop minor to severe issues that necessitate troubleshooting and/or professional a/c repairs.

What kind of issues might your air conditioner develop as it ages? Read on to learn about three of the most common air conditioning problems and what you can do to troubleshoot them.

A/C Won’t Turn On

If your air conditioner doesn’t appear to be turning on, you may have one of the following common issues on your hands:

●        Dead thermostat batteries

●        Faulty thermostat or thermostat set to the incorrect mode

●        Tripped circuit breaker or blown fuse

●        Faulty a/c motor

●        Wiring issues in your house

To figure out what’s going on, check your thermostat first. If it has batteries, see if they’re in working order. Try replacing them to see if that solves the issue. If there are no batteries, double-check that the device is set to cooling mode. If it’s not, set it to the proper mode and see if the system kicks on.

From there, you’ll want to check your circuit breaker or fuse to see if anything tripped or blew. Reset a tripped breaker or replace a blown fuse and see if that solves the problem. If that doesn’t work, you may be dealing with a bad a/c motor or household wiring issues.

Call an air conditioner service professional for a complete diagnosis to determine if you need a new air conditioning unit or just need an electrician to repair the wiring that controls the unit.

Air Conditioner Not Cooling

If your air conditioner appears to be blowing warm air or doesn’t cool your entire house evenly, the issue is likely due to one of the following problems:

●        Refrigerant leak

●        Ductwork leak

●        Damaged fan or compressor motor

●        Faulty thermostat

Although you can attempt to troubleshoot any of the above issues yourself, it’s likely in your best interest to hire an a/c repair specialist for the job. Leaky ductwork is tough to detect on your own, and a damaged motor inside the a/c unit can also be difficult to find and fix or replace. If you’re dealing with a refrigerant leak, only a professional should handle that as certain types of refrigerant can be hazardous.

You may be able to diagnose and repair a faulty thermostat on your own, but if you’re unfamiliar with wiring or how to troubleshoot a thermostat, it’s best to leave the job to a pro.

Frozen Evaporator Coil

If your a/c isn’t cooling your home as it should, it may have a frozen evaporator coil, which can result from a number of problems with your HVAC system. Most commonly, frozen coils are due to one of the following issues:

●        HVAC filters that don’t get changed often enough

●        Blocked vents (do you have furniture or other items in front of one or more vents in your house?)

●        Ductwork blockage (sometimes debris or even critters can block a duct)

●        Faulty fan

If your filter is filthy, change it ASAP. And if you have furniture or other items directly in front of any of the HVAC vents in your home, move those things out of the way to allow the system to get sufficient airflow. Anything that might prevent your intake and return vents from having unimpeded airflow can force the system to work harder than necessary, which can easily cause the coil to freeze.
