Really smart guys that know their business very well and were a real pleasure to work with. Courtesy goes a long way..!! Kudos to them..!!“

“Ivan was very professional, did a very good job. Would highly recommend him to others.“

“The tech (Tom) was courteous, on-time, and quick with our A/C tune up. It gives me peace of mind knowing our A/C will be ready when the really hot weather hits! Thanks to the awesome team at Olson Comfort Services... excellent job!“

“Outstanding. Top notch from top to bottom. This is a throwback company who will give you an honest assessment of what needs to be done, how best to do it at a reasonable price and get the job done right. In an era of you get what you pay for this is a prime example. I could not give a higher recommendation. You may even learn a thing of two along the way as well.“

“Excellent service, advice and yearly check ups I have used them for years, respond right away“

“Highly recommend this team for any mechanical needs! Quick response, detailed updates throughout an extensive multiple unit commercial HVAC issue. Austin was absolutely incredible providing full details as he went unit to unit making repairs, notes, and getting us back up and running!“

“Great company & nice people to do business with. I needed my yearly furnace tune up & I refused to deal with a company that I'd used for many years as the employees became intolerable & the management didn't care. I decided to give Dana Heating a chance & I'm so happy I did! The previous company was charging monies & as I found out through using Dana that company didn't do what they were suppose to do & that's maintain the furnace. That company quoted me prices & parts I didn't need (5 yr old furnace they installed). I appreciate transparency & honesty in which Mike from Dana Heating provided. He was very nice, professional, & showed me everything that needed servicing which was the basic maintenance tune up. I'm glad to have hired them & definitely will hire them again for future jobs while highly recommending them to everyone. Also they've been in business for over 35 years! That alone screams they know exactly what they're doing to stay in business this amount of time which speaks volumes! I appreciate a company that delivers true customer service without the cover-ups which lies inconsistencies just to fool the customer into purchasing items that's not needed. If you want a company that'll treat you with honesty & respect without breaking the bank give Dana Heating, Cooling & Supply a try!“

“Was able to come out at last minute notice, diagnosed my issue, explained what was wrong clearly and concisely and had my Hvac up and running the same day.“
