"Great team! Mark, Sergii and Pavel replaced my furnace and installed an AC. It was a real pleasure to work with them. Mark listened carefully and provided several options for me to choose from. He was also flexible on scheduling the work to match my family needs. Sergii and Pavel performed the installation exactly as planned, kept the house clean, and payed a lot of attention to the aesthetics of the visible parts of the system. They explained to me where they'd run the lines, what were the options and why they preferred one over the other. I'm very happy with the choice of brand and model and with the installation. The team really cares about their customers. Thank you!"

"Thermostat was out for some reason. Technician spent half an hour testing. Went to the furnace and A/C unit open each and tested. Not sure what he did and went back upstairs to the thermostat. He didn't say a word until I asked him what was the problem. He said apparently a connection (electrical) was loose. He went on to continue his business then left."

"The contractor was friendly, found the issue to my HVAC heating system, repaired and provided alternative solutions should I need to replace the system due to its age."

"Irbis was very responsive. Very communicative which I appreciated. My only question/concern was value. Their technician was complete with the repair in 20 minutes. The charge was a little over $300. I never received a receipt so I was unable to validate the charges. I was happy to have my AC running, so I wasn't going to be be short sided with the big picture. I would use Irbis in the future. Now I know I need to ask for an estimate 1st.\"
