Air Conditioner Maintenance

We are so thankful the long winter is behind us!  How quickly our thoughts can turn to air conditioning as the temps may be close to 90 degrees today!  Your air conditioner is probably one system that you have not thought of for quite awhile, but you should take a look at it soon to make sure it performs optimally when you need it to.  The following article is from Home Energy Resource MN:


Your air conditioning system must be kept clean in order to cool your home efficiently. Cottonwood fuzz, grass, leaves, and dust can accumulate on the coils of your air conditioner causing it to work harder and wear out sooner.

Time Needed:	30 minutes
Frequency:	At least 2 times per year summer
Number of steps:	5
Tools you might need:	safety glasses or goggles, garden hose with spray nozzle, toothbrush, rake, pruning snips
Skill level:	easy
What if I don’t do this?	Higher energy bills, decreased cooling efficiency, higher repair costs, shorter appliance life

Step 1: Locate Appliance

Locate and inspect outdoor air conditioning unit (condenser).

Step 2: Plan Ahead For Maintenance

Assemble the tools that you will need and create a safe workspace.

Step 3: Keep It Clean

Turn off power to the air conditioning system. Clear away obstructions and clean debris from the appliance. Prune away excess plant growth. Use garden hose with spray attachment spraying from the top of the coils down. Spraying downward will help wash any dirt or debris to the ground. For stubborn spots use a toothbrush to gently brush debris from the coils. Important! Avoid damaging coils! They are very delicate.  Always contact a qualified service company if you suspect problems

Step 4: Inspect For Problems

Inside your home, locate condensate drain line. Be sure to keep this area clear and the drain line clean. When your air conditioner is operating it removes moisture from the air which must be allowed to flow freely to a drain or condensate pump. Inspect around furnace for condensate leaks. Evaporator coil. Evaporator coils should stay clean if furnace filters are replaced regularly. If an evaporator coil must be cleaned, it should be done by a qualified professional.

Step 5: More Information

The furnace air filter must also be changed during the air conditioning season.

We are going to enjoy the next few days with our windows open, but I'm planning to clean our AC unit so when the heat and humidity move in for awhile we will be ready to cool off indoors.  

Good luck to all of you fishermen out there ~ I'll tell you my fish stories next week!
