Best Heating & Air Conditioning / HVAC In Sun Prairie

“Dan and Ian came the same day I called. They explained my options: repair or remove bidet. Ian fixed the problems and we were able to keep the bidet. They arrived timely, were courteous, knowledgeable, friendly, and professional, all of which inspired confidence. I will call Cardinal for any future plumbing, electrical, heating, or cooling problems. Service was exceptional! Price included a Cardinal membership; the charge for the service call was very fair.“

“Mike G. Did a wonderful job of servicing my Heating and Cooling unit. A lot of the problems that I had were due to the poor design of the Architect on the building itself for exhausting the system, especially needing to exhaust the warm air in air-conditioning mode. Mike found to work around and we also installed a new 20 amp breaker as the 20 amp breaker we had was getting weak. Mike was very communicative with us. He was very straightforward and very honest that I appreciate very much and I would highly recommend Action to anyone.“

“Put in an AC/Furnace for my mother. Was prompt, knowledgeable, did a great job, and cleaned up everything. Price was very fair. Highly recommend!“

“On 2/4/2026 our 2011 Carrier furnace wouldn't stay running and was filling our home with toxic gas.

I decided to call Bohling and thankful I did.
Lucas answered on the second ring and got us a new, two stage Armstrong furnace the same day! The quality of the furnace and sheet metal is outstanding. One could anticipate paying a higher price due to a short notice call. It was actually generously the opposite. WHAT A BLESSING TO HAVE YOUR HELP.“

“Will definitely do business with them in the future. Fast efficient and friendly. Great customer service from receptionist to furnace repair man. Highly recommend.“

“Unfortunately we found mold in our basement which had infiltrated our heating system and duct work. Nick at Ducts on Call was recommended as someone familiar with remediating mold in HVAC systems. Bottom line is that it was clear he knew what he was doing and he and his crew did a great job. The before and after photos are, frankly, shocking. Thank you for your work. We are now living back in our home safely and grateful.“
