Dylan is a pleasant and professional technician. He called he was on his way and arrived as he said. Interstate Heating also sent a text and email about his arrival; there is also a link provided to a real-time map. He went straight to work and performed a thorough inspection and testing of the furnace. I feel confident we will have a comfortable winter. If you have Dylan come to your house, you too should have a good experience. Dylan, thanks again.

“Josh is the best. No one works harder. Our house is old and there have been multiple add-on HVAC units along the way. It is complicated and we've had numerous issues along the way. He is great about informing us what is going on and working to resolve any problem.”

“Jake was out early and got our unit repaired on one of the hottest days of the year. He recommended a replacement unit as ours is over 30 years old. He'll be back to replace.”

“Josh did an awesome job finding out what the problem was with our equipment. Very thorough when trying to find out what was wrong with our system.
Ordered the parts and repaired the system. Very knowledgeable, Respectful and professional. Answered all of my questions and gave me some helpful hints regarding our units. I was very pleased with Josh and Jake. I would definitely request these technicians for future work.”

“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.”
