Tristan came out to get our A/C back up and running. He went through the troubleshooting and kept me informed all along the way (I appreciate that!). He found the communication (wiring) between the two units was bad and ran a temp wire to make sure. Thankfully, the system started up. Then, he moved the wire to a safer location until someone else can come out and re-wire professionally.No issues! Tristan was very easy to work with and would recommend he come out for our next visit.Highly recommended! It was a pleasure doing business with Interstate again.

We had the pleasure of working with Jake on short notice while preparing to sell our home. He quickly familiarized himself with our in-floor heating system, reviewed the setup for accuracy, and performed thorough thermal scans of the floor. His deep knowledge and clear communication helped put our buyers at ease and addressed all of their questions. While no repairs or service were ultimately needed, I wouldn’t hesitate to recommend Jake—his expertise in these complex systems is rare and incredibly valuable.

My issue was a simple fix. The evaporator coil drain elbow was plugged causing the water tray to over flow and cause water to leak on top of the furnace and floor. What was exceptional about the service was the technician (Eric) took the time and showed me how to address the issue in the future on my own. He even took the time to take the evaporator panel off (3 screws) and explain how the system works and where the tray was. Eric’s care in teaching me was outstanding. Great customer service by Eric!

Eric Osterman was recently to our home for our annual A/C system preventative maintenance. He was very professional, thorough and answered my questions in a manner I found easy to understand. The good news was Eric discovered and quickly replaced a key component in the outside compressor that would have eventually failed preventing the home from being cooled. That is the value of their preventative maintenance program. Thanks Eric!!!

July 2nd and no air conditioning! Eric just left and my unit is running again! Interstate Heating Company is an excellent provider of both service and replacement of heating and air conditioning equipment. I've used this company at my home and commercial building on a number of occasions. They put a new furnace in my duplex this past winter. Always top notch people, timely service and reasonable pricing. I recommended Interstate to a friend whose commercial building lost heat while he was out of state. Interstate came right out and got his heat back on. That's a great company!Mike Todd Okauchee LakeMilwaukee Lawn Sprinkler Corp

Interstate Heating and Eric get 5 stars from us. My elderly mother's central air went out just before a heat wave. Eric was able to get a quote written same day, I signed it on a Saturday and by Monday morning the crew was installing the unit. 8 hours later the house was back to 72 degrees. The heat wave rages on and we already have the new unit. Great service and great crew. We are very pleased with the work done and recommend anyone work with Eric and Interstate Heating.

“The two service technician, Tristan and Besto performed a seasonal service check-out before summer usage. They were excellent and provided me key information about my air-condition unit, filter, and brought to my attention the two vents in the storage room that we were not even aware of since we just moved into the home in late December. I'll be sure to use them again if anything would go wrong and/or for regular service maintenance and request the same two technicians.”
