Amazing service
The person that came for the service call and the two people that came to do the new install were all great. Friendly, kind, knowledgeable and productive. Very thankful for their service. Would highly recommend!
If you’re looking for integrity and value, run far away from OSA. A quick peak at their BBB account says it all. It is on good faith that I share that the project manager Joshua Fernandez employs his family members, friends and even creates fake accounts to give false reviews so ratings go up. Read between the BS and do your research before signing anything with these “professionals.” It’s worth saving your money and sanity.
It's the best hvac company in the area fair prices awesome job
OSA installed my HVAC in 2017 and I felt at the time that they did a good job. I had direct contact with the technician who answered any technical questions I had. The HVAC sprung a leak this month so I asked OSA to come out to look at it. The woman who makes appointments is awful. I tried to tell her when my tenant had availability and she would send an appointment for an entirely different time. Then when the technician came out, he told my tenant that something was installed incorrectly. He ended up replacing our condensate pump and filter ($125 service call, $210 for pump, $15 for filter). When I got the invoice, I had questions about the work...did the technician attempt to clean the condensate pump before replacing it (it was only 4 years old so I wanted to understand why it needed to be replaced so soon), and what was it that was installed incorrectly? The woman who makes appointments called me and basically read what was on the invoice which had no mention of what was installed incorrectly or what was included in the diagnosis that resulted in the pump replacement. I told her that I wanted information on what was installed incorrectly and asked that the technician call me. She said, "That's not going to happen." Perhaps OSA's technicians are good, I'm not really sure. But I won't be using them again, due to this woman's lack of customer service.
Working with OSA and Josh was amazing! They did a great installing a new gas heating system and tankless hot water. So happy with service and responsiveness!!
I have been building houses for 10 years and I only use OSA Heating. The technicians do a nice clean job and Josh the project manager makes install process smooth and efficient. Definitely recommend these guys.
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 :)
La mejor compañía de mantenimiento e instalación de aires acondicionado y calefacción
Great experience. I called early on a Sunday morning and they responded and were at my home within an hour and a half. Professional, on-time, reasonably priced and very helpful. Highly recommended
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.
Showed up on time, figured out the problem with my a/c, and fixed it.
It is always a pleasure when dealing with professionals who understand there industry. There are helpful and perform high quality service and installation. Everything looks and functions very well. Thank you OSA.
NEVER do any business with these sharks. Paid for a service filter was never changed and customer service is the worst!
I received same day service! Friendly service and did a great job. Thank you!
Great service ! I had no heat and they came right away!
I will never look anywhere else for heating and cooling needs! Josh made everything so easy and saved me a bunch of money. Thank you OSA!
I’ve been waiting years to replace my home system and these guys were the perfect ones for the job. Great team work every one. It’s fuzzy warm now! Thank you
I enjoy working for the OSA and our dedicated staff. We work hard to help clients and customers everyday. It’s a great way to serve the people of Connecticut.
Honestly, just all around good service. Financing was easy. New furnace done!
