In mid-2020, I hired the Cosmos team to replace a 20ish year old HVAC system. They recommended we replace our old electric only unit with a AC/heat pump combination, citing that it would save us money. Due to the pandemic, they were only able to source Trane manufactured units, not Carrier like they had in the past. We decided to move forward and once the system was installed, it would make a real...

My heater broke down early January and I had Cosmos come out to see what was wrong. HVAC unit needed replacing. They walked me through my options and gave me a fair price estimate and answered all of my questions. They were straightforward and easy to work. I highly recommend them.

No problem with scheduling. I requested a quote and was contacted quickly to set up an appointment. The estimator arrived within the scheduled window and conducted a review of our current system and made verbal recommendations. The estimator mentioned that there may be an issue with availability of the unit he recommended and that he would follow up with us the next week with more info. No follow ...

Mr. Thackson, we are truly sorry for the inconvenience. We spent nearly 3 days to find the right system that is in stock and ready for installation. Due to the Pandemic, inventory has been very low and we would have to wait for the equipment to be available. It has been like that since May of last year. We are usually responsive and it shows on our ratings and reviews. This was just a simple wait ...

I suspected a problem with the furnace because of the exhaust odor and was very concerned about the safety of the system. Called Cosmos first thing in the morning and George came by between already scheduled appointments and determined the odor was normal carbon monoxide exhaust through the exterior vent and the unit was safe. Very impressed and am moving my annual HVAC maintenance contracts and a...

Wow, these guys are awesome! They responded quickly to our request for a proposal, came out with masks during covid, evaluated the situation without complaint (the a/c is in a really tight attic space and it was VERY hot) and gave us a reasonable proposal. They got the work done very shortly after we accepted the proposal. When they arrived to do the work, they were meticulous about putting down p...

George came out and did a quick fix that slowed the flow of water, but determined that it either needed repair or replacement. Since the unit was 17 years old, I opted to have it replaced. Gus came out the next day with a new air handler and removed the old unit and replaced it with the new one. They did it far more quickly than I anticipated, and now everything works perfectly.
