Great experience today. A/C problem diagnosed, part was on board. Chris fixed unit and A/C works great. Chris checked that my part was under warranty. Price was competitive but service often outweighs the price. Thank you Chris and Interstate
He was very thorough and fixed the problem in a timely manner. He also left the area beautifully clean when he was done. He was also very professional.
Great service from the young men. Good group of guys. Very friendly and skillful.

“Friendly customer service experience when calling. We needed a service call for our AC not working. Thankfully, there was an opening same day and our service tech, Josh, was very kind and explained the problem and how it was going to be repaired.”

“We were very satisfied with the prompt response and service from Interstate, and especially Eric who came to our house and replaced the capacitor in our air condition compressor. He was very personable and courteous and he seemed to know what to look for and quickly replaced the capacitor. We would highly recommend him and Interstate to our relatives, friends and associates.”

“Two service technicians came on time and replaced the secondary heat exchanger in little over two hours. They were efficient and courteous. I have had Interstate do maintenance on my furnace and A/C for over 13 years. They are fair and upfront with pricing and any component failures. I would and have recommended them to my friends.”

“Casey was great! Arrived on time, with text notification. Upon arrival did a check of the system and provided a thorough explanation of what the potential causes were. Then, I went to the outdoor unit to investigate and, thankfully, found no serious issues. Also checked the main unit in the basement and found no issues.

Great visit!”
