When you are at a point when you are looking to get a new furnace or air conditioning system in your home there are a few key things to look for when choosing the right equipment or hvac contractor.
You will want to get at least 2 to 3 estimates any more than that you may be just wasting your time. Make sure you are bidding brand for brand Seer for Seer and Apples to Apples. (There Is A Huges Differences In Some Brands Beware.)
I have found in my experience when homeowner calls and get 5-6 bids on 4-5 different brands they tend to be more price driven than quality and a lot more confused by which way they should go.
To find out about the top brands check Consumer Reports, After installing and servicing I have found Trane Furnaces and Air Conditioners have proven to be the most reliable and dependable units there are on the market today. Consumer Reports is very accurate when it comes to equipment with the most service calls, again make sure you are looking at the top four not the bottom feeders.
When a heating and cooling contractor comes to your home to do a estimate, make sure the take out there tape measure and do a heat load calculation, those that do not do this important action do not go with. The key to having a great heating and cooling system in your home is to have it sized and installed right.
The most important thing besides the quality of the equipment is the installation.
This is where you will notice the price difference as well, a good contractor will phrase the value of there installations and show you in detail what there company will do during the installation of the equipment. If you find that it is more expensive than what you intended wait and save to go with the system you want you will be glad you did.
