"Failed permits I have had MAJOR problems with this company. They started out strong. They replaced my unit and my ductwork which seem to be going smoothly. They helped me out at the beginning. The first unit was put in 02/2024 also the ductwork was put in new. It working great forr 5 months. THEY SENT 8 MEN IN HERE TO FIX THE PROBLEM.. to making up excuses of why it wasn't working, to adding freon twice in a week to a brand new unit. Worst after 8 visits, one of the sides was glued shut so they couldn't even look at the coil. The last tech , took off the side, after getting it unglued. There was about 4 inches of ice on top of the gold coils. Wow! These are trained HVAC technicians? Licensed??? Only one, that realized it was glued shut, after 8 visits? I probably have 30 pictures since the day they put the first unit in Scarey. How pathetic??. Only thorough technician, I asked to call the Lennox Rep to follow up the problem. Placed 7/24 no permits. Failed 2x Help "

"Fantastic work and the plumber who can out was amazing! I really enjoyed the overall experience in what was a stressful situation I felt that the pricing was not clear to me in that each plumbing would be charged $250k, resulting in $1,250 for about 2 hours work. I was very satisfied with the work and tried to be as nice as I could be but feel surprised by the sticker when the plumber was already out at my home. Just ask questions on costs before engaging anyone moving forward. The guys were good people and I don’t no mind paying a little more for great work on an Easter weekend… just communicate with me so I am not surprised!"
