OSA Heating & Cooling

Horrible! Stay away from this company! They had me freeze along with my dog at home no heat either an unfinished job. Charged me a horrific amount for a job that was messy and not complete. Had them back for a hearing issue and r they asked me for almost one thousand dollars again! Be careful! Don’t use them as you will regret! Contacted owner, no answer. Manager does not care and does not know client services. Tech is confrontational and rude! Do not use them! Left me in the cold and with an unfinished job! I contacted Hellas in norwalk who said this is a fire hazard for me and the occupants of the home.

OSA did a great job on my AC and new duct work. I highly recommend them for their fair price, quality work and great communication by Josh, the project manager. Josh was very responsive and clearly communicated everything to me. He was at my house three times per day checking in on the crew, making sure things were progressing the way we had discussed and keeping me updated all along the way.

Truly a horrific experience with the manager, John. I've never worked with someone so rude and indifferent. Three separate visits had to be made for a simple replacement. For the second scheduled visit I didn't even get a call to say they weren't coming until a half hour AFTER my appointment window and when I asked if we could reschedule for that weekend since we had been waiting on the part for over a week, John's reply was "I don't work on the weekend." The technicians that came out were very friendly and did their job quickly but will never use this company again because of how we were treated. Buyer beware for sure.

I had a great experience with OSA from the start of of our installation to the end of it. Josh their sales manager kept us informed every step of the way. The owner personally came out the first day of installation and managed the project. The installers were knowledgeable, helpful and respectful. I would recommend OSA to anyone who is looking for a heating and cooling system.

Josh went above and beyond to meet all our needs, he's very friendly and extremely professional, he was always a call away ready to answer any question he is a very knowledgeable, and overall great to work with! the techs were always on time and finished the job as expected. I will recommend them to all my friends, family and clients :)
