During an extreme cold spell this week at our home in Lake Hartwell we noticed our heating system was having a difficult time reaching temperature and that the system seemed to run constantly. We do not live here full time as this is our second home and we were there for the weekend. We finished our basement in 2010 and had a new Trane system installed by McGee and it has worked flawlessly up to this point. I called about possible service the next day as I knew their service folks would be very busy during this cold snap and snowfall. The lady(Anne) was extremely polite, asked what the issue was, took down my name and number and said she would have the technician call before coming out. Three hours later the phone rang and the technician(Lance) said he would arrive in about 15 minutes. Ten minutes later he was at the door. Lance was fast and efficient and explained to me his every move in testing the system, identifying the problem, and recommending procedures for us to better manage our heating and air needs to help keep energy costs down. Upon completion of the indoor system Lance went outside to check the compressor, etc. Upon his return he entered with invoice in hand to inform me there was good news and bad. The bad news was that there was an expansion valve faulty in the unit and a new part would be ordered. The good news was the part will be adequate for our needs until a new part was installed as it was functioning but not as efficiently as it should be. The really good news was that the invoice amount was zero as we have a ten year warranty on our system so no charge for service call or parts. I hope Lance is the one to return and install the new part, as he was very personable and professional. To say we are pleased with Mc Gee in Hartwell would be an understatement. Highly recommend these folks!
