Mark Olis HVAC

"Our heater was old and it broke. A friend recommended this guy to us. From what my dad said, (I was at work so I don't know what exactly went down) this guy wasn't available right that day when we called, which was understandable, but he found a spare part for the old furnace that he quickly installed as a workaround for us to last the next few days until he was available. Considering this was during a time when it was below freezing, going out of his way for such a kindness is greatly appreciated. When he came over to install the new furnace, it didn't quite reach the top, so he made a sturdy metal foundation for the furnace so that it could reach. Really great guy! I'm not saying going above and beyond like that is something you should expect every time, just something that I noticed and found really thoughtful. New furnace works great!"

"In January, my heat pump froze up due to a leak. Since my HVAC system was almost 14 years old, I decided to have both the air handler and heat pump replaced. Mark quoted me a more reasonable price ($4000 less) than larger companies. I appreciated his expertise and professionalism before, during and after the installation process. I highly recommend Mark Olis for your HVAC needs."

"I researched a lot of companies before we needed our AC and Furnace replaced. Someone recommended Mark to us and we decided to go with him since his pricing was so much better and I was discouraged by bad workmanship and reviews with other companies. Mark is professional, efficient, fair, and his workmanship is so much better than the other large companies. Highly recommend."

"I highly recommend Mark Olis for any HVAC needs. I have been using him for years for both my commercial and residential properties. What I liked best about Mark the first time I met him was he knows how to fix things, he’s not trying to upsell you into buying new units. He has a real mechanical mind and is very talented with repairing things, even old furnaces and air conditioners. I really appreciate that about him. It’s hard to find honest tradesmen that have the skills to repair things and not just replace them. When I did decide to invest in new units, his pricing was incredibly fair and more than reasonable. He has done very nice, clean jobs at replacing several units for me and I could not be more satisfied. I will continue using the services of Mark Olis."

"Mark helped me with choosing the right system for my house. He did a phenomenal job and there were no issues at all with the installation process. I recommend him fully if you need any installation or repair work done!"
