Get matched with top central a/c installers in Danbury, CT

"Installed a 4 zone Fujitsu ductless heating/cooling system in ONE day (13 hours), and our historical house isn't a typical install. I got 2 other estimates that were were $5,000+ more. Had a unit installed in our kitchen (9k BTU), living room (18k BTU), den (9k BTU), and attic (18k BTU). For example, today is a humid 90 degree day and I have the units running on dry mode at 70 degrees. It's amazing, so far. I strongly encourage you to use MSD for your AC/heating needs. 100% honest, fair, hardworking, respectful, and nice overall guys."

"It was a superb experience. From the visit by Bruce the sales representative to the installation day to the follow-up from Petro, every single person we interacted with was helpful and professional. When Bruce arrived to do the assessment, we spent time going over the heating needs in the house. After a thorough inspection and measurement of the house, we sat down. He showed me a few options, all of which were going to provide good service. I ordered a unit at the end of that meeting. The installation day was just terrific- the entire work crew that showed up were everything I would hope to find: Upbeat, informative, hard-working, focused. The job was finished before end of day as promised. The heater room is now immaculate, with new piping and a new heater. It was like watching a pit crew at a NASCAR race. Everyone had their tasks, they moved carefully but quickly. The materials were all laid out in order, etc. Just a totally professional approach to their work. The crew boss answered any questions I had. The follow-up for a normal inspection of the furnace chimney was scheduled the day after the installation. I’ve gotten calls to insure we are satisfied with the work. Satisfied barely covers it- I am pleased to write this kind of review. Without hesitation I will recommend Petro to friends and family throughout the Philly area. Peter A. Elkins Park"
