“Had 551HVAC install a ductless mini split in our sunroom last month. The technician really knew his stuff- explained the sizing perfectly and why certain placements would work better. Installation was clean and thorough. They tested everything twice and showed me all the features. Only small issue was they arrived about 20 minutes late, but they called ahead. System works great and our sunroom is finally usable in summer. Would definitely use them again for our other AC needs.”

“Called around for mini split quotes and 551HVAC responded fastest. Scheduling was easy and they were super professional throughout. Tech wore booties, cleaned up completely- you'd never know they were there. Explained the maintenance needs clearly. Price was fair compared to two other estimates. It slipped my mind to incquire about their maintenance plan tho. Overall excellent experience with their residential HVAC service. Highly recommend! ”
