"Excellent. We couldn't be happier with the work Legacy did. The people (Raymond and George) were punctual, friendly and very considerate of our home. They correctly resized and replaced our air ducts and installed a Reme Halo. I inspected the work they did and was very impressed with their work. Air circulation in the house is 100% better and stronger, a great improvement."

"July 2017 OAT +101 (F) -one of my AC units stopped working. I called them at 3:30 P.M. Wed. and they tried to to help me that same day , but of course, with the temps in the 100's they were very busy with other emergencies. They got to me first thing the next day and had my A/C up and running within a few hours. Great service! Great communication! I would definitely recommend them. They will do all my future HVAC work."

"The first technician added coolant and thought the problem was fixed. Later the same day a second technician arrived because the unit was still not cooling. The second technician discovered a broken part on the outside unit and replaced it. The second technician was very thorough and determined to find the problem. The first trip charge, with coolant, was $476.42. There was no service charge for the second trip, only for the new part, an additional $198.38."
