Mark's reputation precedes him, and his work stood up to all the positive reviews he's received. Mark installed a two-stage variable speed system (A/C and furnace) for a much more reasonable price than the larger companies offered. He also repaired an auxillary heat pump vs trying to sell me a new one. The difference with Mark is he tells you what you need without the upselling headache. Larger providers tried to sell humidifiers, ionization add-ins, extended warranties, etc, whereas Mark asked questions to determine if I really needed them (I didn't). Mark shows up and does what he says he will do. It's a no-brainer to use Mark in the future as well as refer others,...read full review
I have been using Mark for a few years now, maintaining our HVAC systems both at our old house and now at our new house. He is very responsive, honest, and a great trouble-shooter. He thinks like an engineer which I appreciate. Mark recently installed a new Heil HVAC system (2-stage gas furnace and 2-stage A/C) in our new home. The installation went very well and the new system works great! I would highly recommend Mark Olis for any HVAC needs.
Mark does a great job identifying the issue and explaining the problem before the repair. He definitely has the mindset of fixing it first. I definitely recommend him and have been using him for years.
