Frequently Asked Questions

Q.  I need to replace my air conditioner,  my furnace is still working fine- do I need to replace it too?

Think of your air conditioner and furnace as part of a total system.  That system will work better,  longer and more efficiently if all of its components are matched in capacity and efficiency.  A mismatched system-one that mixes old technology with new- could decrease system performance and overall comfort.

Q.  What Is Seer?

A. Seasonal Energy Efficiency Rating

Q.  Can you warranty my existing air conditioning?

Yes we are licensed to warranty and service all brands

Q.  Can a leak be repaired

      more than 5 years old.  Otherwise it is more cost efficient to replace the existing

Q.  How often should filters be checked / changed?

Whether your filters are pleated, disposable, electrostatic, or electronic, one thing they all have in common, and that is most home owners tend to forget, "that they must be kept clean".
Failure to do so causes premature part failure. They should be changed between 1 and 3 months depending on the house or business system design.
