Here is an easy tip to check and clean your central air A/C unit to make sure it is ready for the season.
- Multi-tip screw driver
- Socket set
- 3 inch wide paint brush
- Shop vac

The A/C unit located outside your home or condo performs a heat exchange to allow your system to cool your home. If the coils on the unit are clogged with dirt and dust, the unit has to work longer and harder to cool your home.

I use a 3 inch wide paint brush and a shop vac to vacuum the dirt and dust from the cooling coil fins. On some unit, you may have to remove a grill cover while other can be vacuumed without disassembling anything. Care should be taken to not damage or bend the coils while cleaning.

Inspect the base of the A/C unit to remove any dirt, leaves or debris from the base inside and outside and under the unit. This debris holds moisture against the metal frame and causes the metal to rust shortening the life and requiring replacement costs.
Be sure to check with your furnace/air conditioner repair service at least every 2 or 3 years to determine if your A/C unit needs servicing.
