Here’s what our customers are saying about us:

“Your company recently installed a new Carrier Furnace and A/C system in our home. We were very pleased with the quality of service we received. From David Viegut, who oversaw the project, to the entire team of workers who made this installation, we were most impressed. Everyone was professional, knowledgeable, extremely courteous, answered our concerns, and did an excellent clean-up job when done. The entire job was completed in one day. This is one of the most satisfactory contractor experiences we have had. We will not hesitate to recommend Interstate Heating whenever the occasion arises.”
—Phillip H. Richter

“Just wanted to drop you a quick note to say thanks for all of your efforts in getting us our new furnace, A/C, etc.  The installation crew (electrician included) did a fantastic job.  I’ve shown a few people the installation and they were all amazed at the neat, professional job that was done.  And the whole crew was very friendly and patient with me and my endless questions to boot!

The system is working beautifully.  As you suspected, the temperature difference between the upstairs and downstairs has almost completely disappeared.  And everything is so quiet you can hardly tell it’s on!  I’m almost excited to get my next electric bill to see how much $$$ we saved!  We literally could not be happier with the system.  I’m sure there are a lot more fun ways to spend $10K, but for a necessity this has given us the most benefit I could imagine.  I will highly recommend you and Interstate to anyone that’s in the market for new HVAC equipment, starting with my Dad who has a furnace and A/C that is close to 20 years old! Thanks again.”
