Air
Conditioning & Heating System Maintenance
– Why It’s
Important For Your Comfort & Peace Of Mind
During its lifetime, it’s only logical to
assume your system is going to need an occasional “tune up” along the way.
You wouldn’t think of driving your car 100,000 miles without oil changes
and some kind of maintenance.
 The same is true for the heating & air
equipment in your home. Regular preventive maintenance is the best way to
ensure trouble-free operation and peak performance. It also keeps your
system running at its optimal efficiency levels, which keeps energy usage
– and your energy bills in check.
Pre-season maintenance can help you avoid a
system failure on the hottest or coldest day of the year.
Air
Conditioning & Heating System Maintenance
– When To Do It
If your air conditioning system both heats
and cools your home, you should have maintenance performed in the spring
and fall. Twice a year prior to the heating and cooling season.
