Tristen did a phenomenal job communicating with my husband and I throughout the HVAC system maintenance visit. He ensured that we both understood the implication of his recommendations and potential cost if/when we choose to have something repaired. I HIGHLY recommend Interstate Heating Co., there service always exceeds my expectations.

Fall Update: Eric was back for our heating maintenance. He discovered a wearing component which would shut the system down due to safety. No one wants to be cold in January. Eric quickly replaced it avoiding a winter emergency service call. Great job 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!!!

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!
