Very knowledgeable people. I was really impressed when the owner himself came out the day we signed the contract. He changed a few items i.e. a bigger unit at no additional cost to us. The house was very clean when they left. My only regret was not going through them directly; however I have no qualms with Home Depot. Thanks everyone for making our home a place we look forward to coming home to on a hot day.

The installers were polite the way it use to be, even though they were younger. I thought the younger generation lacked the respect we were taught and they showed us otherwise thanks.

Report
Called for annual service, no problem, 4 years old. Was told that the unit was cycling on and off to much. Two weeks later in a 64 degree home, I wrote a check for $1953.00 only to have NO HEAT the next a.m. Now, I was told the entire heat/ac unit must be replaced. Some repairs, huh? Skilled technicians, huh? I was offered a replacement for ONLY $10,000.00. No way from them!
