We called Home Depot because our AC Unit went out, they were able to come out that day. (This was the third company to assess our HVAC system, we are trying to find the best price). It was the "Yes Man" who are the people that HD works with. We explained what was going on to the person. He went outside to look at the unit I guess he must have used his "psychic" abilities because he did NOT take the cover off the AC unit and still told us that it was blown, AND he only poked his head up in the attic and took a picture of the furnace before he told us that it too was blown and that also needed to be replaced. HOW DID YOU KNOW THAT?? He told us that we need a 5 Ton unit for this house (the other companies said 4 Ton), and started to quote several thousand dollars above the other companies, but wait there was a rebate and financing for it too. If you are looking to install ANYTHING with HD, get other estimates call other companies.
