Replacing an HVAC system can feel overwhelming, but Sergey made the entire process smooth, stress-free, and even enjoyable. His team was not only highly skilled and efficient, but also genuinely kind and super helpful. They took the time to answer every single question I had and explaining everything clearly so I felt confident in every decision. You can tell they really care about their customers and take pride in their work. The installation was done professionally, on time, and with great attention to detail. Everything is running perfectly, and I couldn't be happier with the results. If you're looking for someone trustworthy, knowledgeable, and easy to work with, Sergey is the one. I would 100% recommend him and his team to anyone needing HVAC work!

They performed an inspection, found the problem, and fixed it right away. What I really appreciated was that they also checked the ventilation system and honestly told me that it was clean and didn't need to be serviced. My original request was about the heating not working, but they actually did a bit more by checking everything and even replacing the filters. It was refreshing to see that they didn't try to upsell unnecessary services, which I truly appreciated. I will definitely be using their services again in the future.

We did some research and had multiple recommendations from others for Marc Wilmers. We had them come to our house to give us an estimate on replacing the ducts in our attic. EVERYONE we dealt with was super nice and helpful. They came in with the most reasonable price for the estimate so we decided to go with them for the job. The crew of about 4-5 guys came in the morning and they were done in a few hours. My wife told me they were all super kind and patient. My 7 year old son kept asking to help them and they made a deal with him that if he helped a bit they would give him some money at the end of the job. Of course he agreed and jumped in that offer. So as promised, he got a few bucks when they were done. And they finished the job sooner than they anticipated. Every interaction we had with them was positive. So I'm pretty sure we have a new HVAC company. Give them a shot. I'm confident you'll love them too.

With that, I will say OIG HVAC is the best in their industry. Absolutely top of the top notch! I had to replace the antiquated HVAC system in our home and I canvased many other HVAC companies. I had several look over the situation, provide their advisement and quotes. It wasn't until I had contacted Oleg of OIG HVAC did I finally decide to move forward with my HVAC system replacement. I had previously done my homework and Oleg was the only one who answered all of my questions and went over and above to provide details and additional information which helped us to make the best choice for the needs of our home. We're now two weeks after installation of our new system and it's still a perfect fit. I also opted to have all new ducting which was something I wanted to do as well. The installation from top to bottom was exceptional! True professionals Oleg and his team. They buttoned everything up nice l and clean. Not only did we get a good quality system and great work done, but their pricing was the best compared to all of the other HVAC companies we had previously consulted with. Thank you Oleg and OIG HVAC! You are the absolute best!
