Tips on choosing an HVAC contractor

Helpful Tips 200When choosing an HVAC contractor, be sure to do your research. Buying a new unit can be pricey, but you want good equipment and the job done right. Here are a few tips to help you make the best choice for your home.

  1. Get estimates for the equipment and installation from several contractors. It is not unusual for these estimates to differ by as much as $1,000, so get at least two or three.
  2. The lowest estimate is not always the best choice. Pay close attention to the quality, energy savings and warranty. All of these are worth the extra up-front cost.
  3. Make sure the contractor is fully bonded and insured.
  4. If you are not familiar with them, ask for customer references…and of course, follow-up with the references.
  5. You should receive an estimate in writing. The estimate should include a breakdown of the cost of equipment and labor.  Never do business with a company that gives you an estimate over the phone without looking at the job that needs to be done.
  6. Expect a home evaluation. The contractor should inspect your current system and be able to estimate what you energy bills will likely be with the new system.
