Get matched with top heating and air conditioning pros in Waterloo, WI

"I had been unhappy with another firm in Madison that has worked on both our furnace and central air conditioner, so I contacted Clark, based on a recommendation from Dan of Jenko's garage doors, and checking on Angie's list, where Clark was highly rated. They sent a serviceman (I think it was Kevin) last Tuesday, who inspected our system, which had been installed in 1992, and determined it was leaking Freon. He indicated that repair was not a smart option on an old system and recommended a new air conditioner. Andy came came out on Thursday to give us an estimate. I asked if he could have it installed on Friday, as it was very hot and humid and we were having guests over for dinner. He said he could make it work. On Friday his crew (Jeff and his partner) spent about 5 hours removing the old unit and installing the new one. They were completely professional and thorough. By 5:00 the house was cooling down. I highly recommend Clark Heating and Cooling."

"I've also used Cardinal for electrical and HVAC service. Cardinal has the best service and technicians of any HVAC, plumbing and electrical service I've ever used. Very well run, customer focused business, with prompt service and very fair pricing."

"I've been using Kettle Moraine Heating for my annual furnace and AC tune-ups for a while now, and I couldn't be happier with the service. Khamya Little was professional, thorough, and took the time to make sure everything was running perfectly. It's always a relief knowing my heating and cooling systems are in great hands. The team at Kettle Moraine consistently delivers top-notch service, they're prompt, knowledgeable, and genuinely care about doing the job right. Highly recommend them to any homeowner looking for reliable HVAC maintenance!"

"Very knowledgeable, friendly and worked through the day until the job was done. Great choice for residential HVAC."

"Justin took care to not over sell me. Only what I needed and understood. The install team were tidy, efficient, and educated me about the safety approaches when changing the humidifier filter. That filter and the furnace filter are the same that was used on my old system. They were professional and personable."
