Air Conditioning Maintenance at home doesn’t really cost a lot of money. You can perform simple maintenance check by following these 6 easy DIY Steps on a weekly or monthly basis. But always be sure to take safety precautions and identify the unit installed.
Turn off the electrical power to the condenser unit at the outdoor shutoff. Either pull out a block or move a switch to the off position. If uncertain, turn off the power to the AC at the main electrical panel.
STEP 2 – KNOW THE PARTS OF YOUR AIR CONDITIONING UNIT
Every Air Conditioning has a manual which indicates all the important pieces of your unit. If you don’t get to have one. You may contact the manufacturer.

STEP 3 – CHECK FOR FAULTY WIRINGS AND COMPONENTS
You can also check any electrical connections to make sure they are tight. If you own an electrical test meter, you can check the capacitors in the unit.
Take a look at the contactor switch, and replace it if you see excessive pitting
If you see any of the above problems and do not feel comfortable replacing the parts yourself, always call a local heating and air conditioning expert to do the work for you.
Note: Always refer to manual. If it seems quite complicated, please contact an expert regarding the matter.
STEP 4 – KEEP THE CONDENSER/COMPRESSOR AND FAN BLADES FREE OF OBSTRUCTIONS
On the exterior condenser/compressor, remove the fan cage. Using a screwdriver or wrench, remove the fasteners and lift the cage or fan grill away from the top of the unit. By hand, or with a wet/dry vacuum, clean leaves and other debris from the interior.

STEP 5 – CHECK AND REPLACE DIRTY AIR CONDITIONING FILTER
Look for the filter’s minimum efficiency reporting value, or MERV, which ranges from 1 to 12 for home AC units; the higher the number, the better filtration it provides (and the more energy needed to pull air through it, so balance air-quality concerns with energy costs).
STEP 6 –CHECK AND TEST YOUR AIR CONDITIONING UNIT
Allow the unit to dry thoroughly and then turn the power to the condenser back on by doing the following: First, turn the thermostat in your home to OFF. Then turn on the power at both the disconnect box and at the main panel. Last, switch the thermostat to COOL.
In addition, contact a service technician if:
- the unit no longer provides cool air
- the air conditioning unit emits an unusual smell or sound
- there is any irregular moisture seepage
- the temperature is inconsistent or air doesn’t flow well
If you’re not sure of what you are doing, it is always best to consult your contractor, if you have one or you may look for reliable contractors that is within your location and that offers free consultation.
