Eric serviced our air conditioner; outstanding. Our system is significantly more efficient now that it's clean. Tristan was amazing. He advised me to close vents/redirect air to the rooms that needed more heat and to leave on the fan to protect our HVAC system: : : he did suggest adding a line to the basement to give more heat as well which we will likely do. He was an extremely knowledgeable, skilled and kind service man : thank you-Julianne

“To Interstate Heating team
I can not say enough positive things about your team and technicians. Eric did an incredible job with the furnace maintenance/tune-up, reviewing zone controls, talking about wireless thermostats, and allowing me to ask tons of questions along the way. Eric was extremely knowledgeable, professional, and personable. He helped get the home heating and cooling zones more balanced which will keep the house way more comfortable. Interstate always delivers and I will continue to recommend them to anyone I know who needs HVAC work done. Great job Eric and Thank You!!!

“Your team members arrived bright and early as expected. They got right to work, only stopping to ask questions. In talking to us, the head installer recognized we were not candidates for the upgrade to the thermostat so he changed that out for us. Some other changes were not needed so he again credited us for that.
We have had Interstate for all of our cooling and heating needs FOR YEARS and have always been very satisfied. No difference this time. We are very pleased with the quality of work and installers.”

“Eric was here for our usual fall Gas Furnace Maintenance inspection and answered many of our questions regarding our filters and the air quality in our home. Since we keep the furnace fan on continuously, there were questions about the Aprilaire control board. Some hints as to what number setting to use during the change of seasons in Wisconsin. He also offered information about our Air Quality and what we could do to take care of this situation. He was very professional, and we were very pleased with the exceptional service he provided.”
