Get matched with top air conditioning pros in Jefferson, WI

"Always great work, very thorough for our summer tuneup to get the air conditioning season started"

"This was my first time using Cardinal Heating & Air Conditioning, and it was a fantastic experience. I received a phone call asking me if I wanted to schedule my annual air conditioning check, and when I said yes, the scheduler informed me that she could have a technician come out that day. The technician arrived within a couple of hours and did a thorough check. Everything checked out, and I am ready for the hot summer months."

"They were the only AC company to measure for the correct size air conditioning unit which I would tend to believe the size was correct. My only issue was the price. Now he did say I would be receiving a lesser quality piece of equipment looking at just the price. But the unit I was getting from a competitor was twice the size. Some people say size doesn't matter but I tend to disagree. 14 seer is 14 seer and the fact that it was a 2.5 to me just means it will cool that much faster."

"Installers arrived on time and were professional in their manner and explanations of our new Carrier Furnace & AC. I highly recommend this company."

"Shane was able to schedule a prompt appointment. He arrived on time and performed a thorough diagnostic on the furnace. He identified an issue I was unaware of and corrected the problem with the air conditioner using parts that were still under warranty. I will gladly use his services again."

"Customer service was excellent. Everyone from the person who first answered the phone to the guys who did the cleaning were friendly, professional, courteous, and thorough. We can tell the difference in the air quality already and our furnace sounds quieter too."
