Eric did a great job explaining what happened and made the necessary adjustments to fix the thermostat. I would highly recommend Modern Air Services to everyone I know.

Chad Marquardt

So, our office building is serviced by Ratterree- as that is who the landlord uses. I can say that I am THOROUGHLY impressed with the service Mike & his guys give. We had a few problems with our system due to its age and Mike was on top of it every time with excellent communications. While I should have written this review sooner commending him, todays random call just to check on us personally by Mike made me think this was the time to let everyone know what a great job they do.

If you need a company that won’t leave you hanging, I suggest you call Mike and his team.

Ramesh Ghimire

Excellent company to deal with from purchase several years a go and service check yesterday. Fairly priced and knowledgeable techs. Greg and Gilbert answered questions with knowledgeable information, well done gentlemen!

Paul Anderson

Greg just serviced our two heaters for the winter. I asked about installing a damper in our master BR. He spent time tracing our ductwork & informed me a damper was already installed & showed me how to use it. He also helped with several issues that were not part of the discounted winter service. I ask if he had always worked for Modern Air and learned he had worked at a big service provider but the focus was on the numbers. He wanted to help people so joined Modern Air. Thank you Greg. You always do a great job and I appreciate it!

John Leiss

I have used these guys for years to maintain our ac, or for unexpected repairs and they promptly respond. The office staff has always been polite and responsive. When a repair was needed the technician (Erick) diagnosed the problem and fixed it at a fair cost. I highly recommend them for repairs and service.

Tony Roberts

Excellent work and fair pricing from the technicians. They came out and did everything they could do to avoid having to add more to the current issue. They even replaced the thermostat that was fried due to my mistake of incorrectly wiring it causing all of the issues in the first place. I found them on the Good Contractor’s List and would HIGHLY RECOMMEND this company for any HVAC needs.

Christopher Mullaney

Greg & Alex very professional, friendly and courteous. Great technicians – explained services performed and future maintenance to be done.

Linda Rigdon

We have been using this company since 1987. Never had an issue they couldn’t fix. The employees of this company are fantastic. Would recommend them to everyone.
