Heat may not be a top concern in the humid, muggy environment of South Florida, but central air conditioning certainly is! Your central air conditioner’s condensing unit, among other components of your Heating, Ventilation & Air Conditioning (HVAC) system, needs regular care in order to function properly. If you value cool air and comfort in your home, then pay attention to the following HVAC repair and maintenance tips!
How To Repair & Maintain Your HVAC System
Fortunately, there are plenty of HVAC repairs that are easy and can be done on your own. Follow these steps to maintain your condensing unit on at least an annual basis, and call your local home repair service for any other HVAC repair and maintenance you need!
Shut Off the Power
First, you will need to shut off the condensing unit’s power supply. Open the switch box, which should be located next to the unit outside your house. Depending on the make and model of your condensing unit, you will need to do one of the following:
- Unplug the box
- Remove the fuse plug
- Hit the switch that shuts down the power
You should also turn off the main service panel (which you may have repaired when investing for resale) and wait a few minutes to allow the charge to dissipate before moving forward.
Lubricate the Motor
There will be protective grilles on the side that must also be removed. Unscrew the top and side panels and pull the grille away. Do not remove it, but rather support it on top of the fan lightly and carefully. Then, drop some lubricating oil into the ports located above the fan blade.
Clean the Coils
The next phase of HVAC repair and maintenance is cleaning the condenser coils. Be sure not to bend or warp them as you are clearing away any leaves, sticks or dust. Using a soft bristle head attachment, also vacuum the exteriors of the coil fins and also any debris on the bottom of your condensing unit. Use a hose with a gun to lightly wash the inside of the coils.
Finally, reposition the grille covers and make sure your unit sits level with the ground. Use a leveling tool and if it is not level, adjust the feet to make it so. Once your unit is level, wait about 3 hours before you turn the power back on. Reconnect the switch and turn on the service panel. Turn your unit to cool — and voila! Cold air for everyone in your house to enjoy!
