If your home's air conditioner is having a problem, then it is entirely possible you can fix it yourself. Fixing basic air conditioning issues yourself will save you a lot of time and money. To this end, here are some tips to get you started on the process:
Tip: Start with the Common Failure Parts
There are a few things that commonly fail in residential air conditioning systems. These include:
- furnace blower motor capacitors
- air conditioner run-start capacitors
- air conditioner relays
Each of these parts is inexpensive, and you can safely replace them yourself using basic tools you already own.
Tip: Verify the Furnace's Blower Motor is Working Correctly
To start the troubleshooting process, turn your thermostat to it's cooling setting and wait for it to kick on the furnace's blower motor. If the system doesn't blow any air, then the blower motor is likely the problem.
If you wait for a few moments and the motor doesn't come on or make any noise, then you should turn off the system's power breaker. Turn the breaker back on and try again. If you still don't have a working blower motor and don't hear any sounds, then you will have to call a professional HVAC technician because the motor itself has likely failed.
However, if you hear a buzzing sound but no air comes out of the vents, then the furnace's capacitor has failed. Replacing the blower motor's capacitor is as simple as turning off the breaker for the HVAC system and removing the capacitor and putting on a new one.
Tip: Check the Exterior Air Conditioner's Condenser Unit
If your HVAC system is blowing air, but it is not cold, then there is a problem with the air conditioner's exterior condenser unit. The condenser unit located outside your home should run when your system is on. If you hear sounds coming from it, then you will need to hire a professional HVAC contractor to determine the problem. However, if the unit isn't running, then it has an inexpensive capacitor and fuse that can easily be replaced.
You can buy capacitors and run-start fuses at your local home improvement center or hardware store. Following the directions included in your condenser's owner's manual, you can quickly replace both parts and then start the system again. If the condenser runs and the air is once again cooled, then you have solved the problem. If not, then your system is having a major problem and needs professional troubleshooting.
