First check contractors listed on Angie's List. Check other reviews on the net (google, etc)and even take a look at the BBB rating ,if any. lok for contractors that are members of and have NATE Certified Techs . The ACCa website has a good paper that you can print off on how to select a contractor.

Be advised that the proper design, sizing and installation are critical to the efficiency and longevity of a new system. DOE and EPA websites have a lot of good information on this.

If you have researched brands on the internet and have a brand chioice, see what contractor are on the brands dealer list,on their website.If you haven't researched brands, you might want too, there is a lot of new technology to consider. Two speed compressors, 95% plus efficiency gas furnaces, even a variablee speed compressor( Very efficient, from Carrier).

Most every brand today has a 10 year parts warranty, but cosider buying 10 years of labor( manufacturers warranty).

If you have a gas furnace, you should consider a Heat Pump for the out door unit, it will cool and heat your home inconjuction with the gas furnace.

Electric rate as well as gas are likely to rise as much as 30% in the next ten years.

When it comes time to replacing your heating and cooling systems, it's a good opportunity to consider whether a geothermal system would be a worthwhile investment.

This costs considerably more up front, but it will typically reduce your operating costs by half on a conventional heating/cooling system and by 40% on an "air source" heat pump.

If you call in conventional hvac folks who aren't offering geothermal systems, they're likely to discourage you from geothermal by oversstating the cost, but the Department of Energy says you would expect to recover your additional investment in 5-10 years. If that's true, you win three ways:

1. less expensive in the long run
2. protects you from future energy cost increases
3. environmentally friendly
