Do-It-Yourself A/C Repair TipsNovember 15, 2018
We all know the feeling. It’s a hot and humid day, and you expect a blast of cold air when you step inside your home, but instead, it feels close to the same temperature outside.
What do you do? Call an A/C repair technician or attempt to solve the problem yourself? Well, the answer depends on the problem at hand and your a/c repair skill level. Here are some easy ways to diagnose the problem with your A/C unit yourself and determine if you need professional help.
Check the A/C Settings
First and foremost, you want to make sure that your a/c unit is on the correct setting to see if there even is a problem. Your unit should have a temperature control thermostat and a fan-only option. If it is set to the fan-only option, your a/c unit will not produce any cold air for your house.
Change the Filter
Many a/c repairs can be avoided if you simply remember to change the filter on a consistent basis. Once a filter becomes clogged, it can restrict airflow, which makes your a/c unit less efficient. Additionally, a clogged filter can occasionally contribute to ice building up in your system, so make it a priority to check your filter every couple months and replace it as needed. If you are already experiencing issues, go ahead and change your filter to see if that makes a difference.
Check the Breaker and Electrical Box
The issue might not be with your a/c unit at all! Before conducting any a/c repair, examine the breaker and outdoor electrical box to make sure they have not been tripped and are still functioning properly. Particularly the outdoor electrical boxes can cause trouble because insects sometimes build nests inside them.
Check the Coils
As with the filter, dirty coils can make your a/c unit inefficient. You can use a garden hose to spray your outdoor coils to release any build-up on them. A technician would utilize a strong acid to get rid of the grime on your coils, but unless the build-up is out of hand, using a garden hose should do the trick. Yet, if an inside coil is dirty, you will need to call on professional a/c repair because cleaning these is rather difficult.
Thaw Any Ice
If you notice that your system has built up some ice, you need to turn up the thermostat to a much higher setting or switch to fan-only. Let the fan blow moderate or warm air for a couple of hours to thaw the ice, then the ice should melt and the system should work again. If it does not, you will likely need a professional a/c repair technician to get to the root of the problem.
