Installed a new furnace and air conditioner. They are a Costco contractor. Able to get a gift card to help with the cost. Cleaned up area after they were done. Furnace was giving us a problem 3 months in. They came in and fixed it with no problem within a day. Get 3 years of maintenance agreement with purchase.

I had my HVAC system replaced by McNally's with a variable speed, cold climate heat pump and gas furnace. Their price was competitive and they did a good job with the installation. They have experience with and were knowledgeable about heat pumps. So far the new system has cut my heating bills in half (Oct thru Dec).
