Eric was the service tech - total pro - on time and performed the annual maintenance on the heating and A/C systems. We talked about upgrading existing thermostats to WiFi ones and he had the desired models onboard. In addition, we talked about a possible future garage heating unit install and talked me through it. I would rate service as Excellent.

Chris was the ultimate professional. He repairs the miss wiring of another technician preventing me from having to replace my furnace. I am grateful for his honesty and service and now a future customer going forward. Interstate came highly recommended and it was spot on. Service call cost is the most reasonable of any other vendors.

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!!!

Interstate Heating and my tech Josh, were awesome! I was scheduled for service right away when I called. Josh came to my house, diagnosed the problem and began to fix things. We had to order a part, but the part came in right when he said and he called back to schedule a return appt at my convenience. Interstate has very professional team members from the office to the field and their fees are fair. I would highly recommend 🙂

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

Overall I was extremely satisfied by the friendly, professional support.”

“Superior service on so many levels!
First of all, I was dissatisfied with the company that installed my furnace (in 2018) but needed someone to address an issue that recently arose. I chose Interstate based on the recommendation of a friend and, after was said and done, I was not disappointed.
The first service call revealed that the furnace was, internally, really dirty. Yes, I do regularly clean the furnace filters, but the camera showed that more was REALLY needed. The first serviceman did an amazing job righting this problem, but warned me that replacement might be needed if the furnace cleaning didn’t remedy the issue.
Well, the problem continued so, the following week, I called again. To make a long story short, called at 8 AM . . . serviceman arrived at Noon . . . replaced faulty part . . . and was out the door by 1:00. No service charge, on the second visit, and part had a 50% discount because of furnace warranty. GREAT SERVICE!!!
I did learn something, from this adventure, and that is duct cleaning may have prevented this.
I already have made an appointment, for that service. (I asked Interstate if they could recommend anyone and they supplied me with the name of someone they found reliable.)
VERY HAPPY WITH INTERSTATE’S SERVICE!!”
