How To Repair An Air Conditioner

Having a home HVAC system can be a god-sent in the scorching hot summer months. However, when a problem arises with your HVAC system, it can feel like the end of the world. Fortunately, there are many HVAC problems that you can perform at-home repairs on so that your system can get back up and running without an HVAC professional.

What to Do When Your Air Conditioner Isn't Cooling Your Home?

One of the most common problems homeowners run into with their HVAC system is that it stops cooling their home. This issue can typically be remedied with one of several at-home repairs, depending on the exact culprit of the problem. You'll have to invest a little time in discovering just what the culprit is for your malfunctioning HVAC system before you can perform these simple at-home repairs.

The most common HVAC parts that fail are your HVAC AC contactor and the HVAC start/run capacitor. These HVAC parts are fairly inexpensive to purchase and are the first HVAC parts that you should perform at-home repairs on if your HVAC system is at least five years old. To verify the exact part that you should replace, you'll want to look at the nameplate on the condensing unit. Write down the make, model, and serial number so that you can ensure you get the right parts for your at-home repairs.

Step-By-Step Instructions For Replacing HVAC Parts

Before you attempt your at-home repairs of the HVAC AC contactor or the HVAC start/run capacitor, you'll want to kill the power to your entire HVAC system. Do so at the electrical box. Go to your outdoor compressor unit to start your at-home repairs. You'll want to remove the access panel on the unit. Locate the HVAC start/run capacitor, which looks like a cylinder connected to various wires.

Do yourself a favor and take a picture of the wiring before you start your at-home repairs. An HVAC professional can attest to the necessity of knowing where each wire came from. Use your at-home repair pliers to remove the wires from the old HVAC capacitor and snap them into the new HVAC capacitor. Finish up this at-home repair by securing the new HVAC capacitor into its position inside of your HVAC outdoor compressor unit.

While performing at-home repairs on your HVAC outdoor compressor unit, it's a good idea to replace the AC contactor. Locate the contactor inside of the access panel and remove the existing wiring. As always with at-home repairs, snap a picture of the wiring so that you remember how it goes back on. Finish up your at-home repairs by connecting the wires to your new HVAC AC contactor and resecuring it to the HVAC unit.

If your at-home repairs don't solve the problem that you're having with your HVAC system, it's time to call in an HVAC professional. While there are many at-home repairs that you can perform on your HVAC system, there are some issues that require special equipment and knowledge that only HVAC professionals have.
