Who We Are

CMI-AIR is the residential division of Consolidated Mechanical, a local, family-owned commercial air conditioning company with more than 30 years of experience.

Over the years, owner and air conditioning engineer Marvin Koskela was frequently asked by commercial customers to evaluate the comfort of their homes. Again and again, he found the same problem: while the heating and cooling equipment itself was often adequate, the residential air distribution systems had not been properly designed, manufactured, or installed to deliver the quiet, consistent comfort people experienced in their workplaces.

That realization created a need for a different approach to residential HVAC, one grounded in proper engineering and thoughtful system design. And that’s how CMI-AIR was born.

"Marvin came out today to repair my air conditioning unit and it was a great experience. He was so pleasant, the work performed was effective and he was timely. I would not hesitate to recommend this company to my family and friends."

Vanessa Reeves

"CMI replaced our AC units about 8 years ago and have stood by their product. They have been to our home to do repairs and routine maintenance and inspections several times. We have always been very happy with our service. I am giving them 5 stars because they consistently provide excellent service and communicate well with us on what they are doing or need to do. It has been a pleasure doing business with this company!!"

Kathy Stieg

"CMI-AIR has been providing superior A/C and Heating service for over a decade! Actually, found them through a maintenance company and we've been with them ever since, through two replacement units, and yearly maintenance services that includes both Summer and Winter tune-ups... Always professional, knowledgeable, and available for follow-up assistance, 24-7. Fantastic customer service (especially Catherine), and world- class technicians (Walter is THE BEST)! They have My 5 STAR Recommendation!!"

Bob Brickman

"I have had the air purifier for several years now and am so glad to have it. I had asthma severely as a child. As I get up in age I want the air in my house to be free of pollutants. I also find I only have to dust my furniture perhaps once a month! Love it!"

Mary Lou Coe

"We have been using CMI for over 10 years and we’re always happy with the results and the technicians are happy and helpful!"

Amber Alaura

"Walter was great! He checked everything with my unit inside and out and tested it as well and was personable, upbeat, and positive the entire visit."

Shelley Freeman-Lent

"We appreciated our technician, Walter, who was very professional, polite, knowledable and thorough. Being new customers, it was nice to feel that we could trust what we were being told."

Pam H.

"My home warranty company contracted CMI to repair my AC. They replaced the blower motor in the attic unit and it works fine now. The technicians were prompt, polite, and professional. I will get on their semi-annual preventative maintenance plan. I recommend this company."
