Specializing in Heating and Air

Has your air conditioning system had its yearly spring check-up?

A dirty, non maintained system costs a minimum of 20% and more often 30% in extra electricity,
this adds up to many thousands of dollars over the systems lifespan. A dirty system is guaranteed
to cost a minimum of $500.00 in extra repair costs over a well maintained system in the first 5 years.
Extra repair costs escalate greatly with each passing year as do extra energy costs.
Add the two up and you can see it's big dollars.
