“Fantastic experience with Interstate Heating. Was referred to them by my dad who had spoken very highly of your guys’ service in home building projects. My wife and I had our furnace go out and your team was quick to come out, assess and quote the project, and install a new, efficient furnace. I am pretty unknowledgeable when it comes to these things, but your team helped me understand what was occurring and made great recommendations on a new product. In addition to doing a great job, the three individuals I dealt with were all very friendly. 5 stars!”

“My remodeled barn I use for an office was 43degrees when I went out to work at 6:45 AM. I called Interstate at start of business at 7:30 AM. Their technician Eric Osterman arrived before 10:00 AM and the furnace was back on line in around an hour. Eric was a total professional and took care of everything. Overall I was extremely satisfied by the friendly, professional support.”
‘- Jerry W.
“Superior service on so many levels!
First of all, I was dissatisfied with the company that installed my furnace (in 2018) but needed someone to address an issue that recently arose. I chose Interstate based on the recommendation of a friend and, after was said and done, I was not disappointed.
The first service call revealed that the furnace was, internally, really dirty. Yes, I do regularly clean the furnace filters, but the camera showed that more was REALLY needed. The first serviceman did an amazing job righting this problem, but warned me that replacement might be needed if the furnace cleaning didn’t remedy the issue.
Well, the problem continued so, the following week, I called again. To make a long story short, called at 8 AM . . . serviceman arrived at Noon . . . replaced faulty part . . . and was out the door by 1:00. No service charge, on the second visit, and part had a 50% discount because of furnace warranty. GREAT SERVICE!!!
I did learn something, from this adventure, and that is duct cleaning may have prevented this.
I already have made an appointment, for that service. (I asked Interstate if they could recommend anyone and they supplied me with the name of someone they found reliable.)
VERY HAPPY WITH INTERSTATE’S SERVICE!!”

“Excellent experience … from review of current system, quote process and installation. My election for an install date for both furnaces coincided with an outdoor temperature of minus 4 degrees. All went very smoothly and the house barely cooled at all. A total of 4 installers and an electrician worked the job, and when they left there was nothing left behind for us the pick up.
Recommend Interstate highly, and I’ve been told I’m a tough guy to please.”
‘- Bart M.

“Our furnace didn’t appear to be running properly and there was a burning smell coming from the vents. Called Interstate at 3:30pm and a very knowledgeable service rep was at our home by 4pm! After determining the cause and weighing options of repair or replacement, we made the decision to replace. This was on a very cold winter day/ night. A new furnace was installed the very next day (arrival at 7:30 am) and completed in a timely manner. All employees were very kind, answered any questions and knowledgeable. I can’t thank them enough for getting out heat up and running!”

“Interstate Heating was a lifesaver this morning (10/16/24). They were very responsive to my needs (that started the late day before).
My situation was this, I had a local company into my home for a furnace cleaning and tune-up (because I had a discount coupon for the work). They arrived at 2:00 pm. After 2.5 hours they completed their work (I’m assuming it took that long because the lead technician had a “trainee” with them. The reason I am assuming that is that every time I went to observe the lead technician was providing direction to the trainee). At the end of the work, I was informed that my Carrier variable speed inducer assembly had failed during a performance test ( I had no idea what that statement exactly meant). Once I had been given that information I was also informed that to improve the performance of my equipment I may need to replace the system’s motherboard as well as move the intake piping from above the gas valve (I didn’t tell the technician one of their associate technician’s had also made that comment two years earlier….no change in condition). All combined the quote was close to $1,500. But that wasn’t the most significant fact. When the technician told me there was equipment failure they didn’t indicate positively that the furnace won’t work due to that component failure. This was at 4:30 pm….which meant it was too late to make a decision about what I was going to do….which meant no heat for the evening. An acceptable ending to this part of the story is my wife and I survived a below-freezing evening in our house!
In the morning, I called Interstate at 8:00 am (I put my information into them both on their website and through their chatbot the evening before). When Ellen answered the phone she had already viewed my input from the previous night. She was very conversant with my situation. We had a longer conversation about my needs and she then directed me toward their appointment scheduler. Within approximately 30 minutes Jessica called to tell me there was a technician in my area that would be available late morning.
Casey arrived at approximately 10:30 am. He would have been at my home earlier but he had to go pick up the parts from the Interstate location. He was able to pretty quickly assess and repair the equipment. The inducer assembly was the only component replaced. Both the motherboard and piping were deemed a “non-issue” so were not included in the repair. The original quote for just the inducer assembly replacement was approx. $500. My payment to Interstate (with the trip charge….which did not include the “go get” parts run that Casey had to do before arriving) was less than $215 (which was over a $250 savings…..).
Casey was highly professional, very timely, very courteous, and a pleasure to work with.
I will continue to be a loyal customer of Interstate (they installed the furnace in 2015 and our AC equipment in 2023) going forward. And will try to restrain wanderings to other company’s because of their “good deals”. I have learned my lesson.”
‘- Mark K.
“As he has done for the last 4 years, the new furnace has been installed. A GREAT & professional service. I will call for him next year. Thank you for the service.”
‘- Floyd G.
“Called, and had technician (Dylan Scherer) arrive that same afternoon.

Dylan did a great job!”
‘- Patrick K.
“This company was fantastic! I called the company they sent someone out for an estimate the next day. And my central air was installed within a week of my initial call. They were very nice and cleaned up well after they were done. The price was also lower than the other companies I called. Would definitely recommend them!”

‘- Joseph K.
“Two service technicians came on time and replaced the secondary heat exchanger in little over two hours. They were efficient and courteous.

‘- Karen H.
“Our 6 year old central air system stopped producing cold air. We called at 8:00 AM on a Sunday and the technician arrived in an impressive 45 minutes. Fortunately all that was required was a new capacitor and we were back in business. Casey, the technician could not have been more pleasant or competent. Fast, terrific service. Thank you.”
‘- Tom L.
“Needed to replace a 26 year old air conditioner and was able to make that happen in 4 days! They also credited my initial service call to the total price of the unit which I was thankful for. My only wish was to have an actual brochure to compare replacement units, to actually see the features and the prices (I am old school in that regard!) rather than looking it up online. Many people my age are not as comfortable with that!”
‘- Karen H.
“Service was good and technician was knowledgeable, neat and on time. My wife an I felt the service charge was outrageous-$640 for 1.5 hours of labor. Before using your company again I will check with other service providers to compare pricing.”

“Interstate was absolutely wonderful to work with. They answered any and all questions that I had. (And I had a lot of questions) They gave me information on when the work would take place and had my Carrier Infinity furnace/ AC unit in very quickly. The installation crew was also very knowledgeable and polite. They also helped me with paperwork for a rebate as well. Please note that Carrier is the way to go….. My old Carrier AC unit was 38 years old and STILL working!!!
I was in construction for 37 years and can tell good contractor people. Interstate was fantastic to do business with!”

‘- Barrie M.
“Had our semi annual furnace & a/c inspection on 4/16. Unfortunately old unit was ready to be replaced-repairs wouldn’t be worthwhile accounting for age of unit.

“We have an annual service contract for our furnace and air conditioner, and this was our first experience with Casey. He is professional, courteous, and thorough. He was a little early for our appointment, which was great. Casey explained what he did with the air conditioner and added refrigerant, with our okay, since it was a little low, although he said it wasn’t an immediate necessity. He also reminded us to be sure to change our furnace filter in the near future. We are very satisfied with Casey’s work. Our goal is to keep our air conditioner and furnace in peak condition, and Casey, as well as the previous Interstate Heating servicemen, have met our expectations. Keep up the good work. Thank you.”

“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!!!

‘- Ken W.
“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.”

“Chris came to our home on time to fix our air conditioner. Interstate called me early in the morning. Interstate was returning my phone call (I had left a message), to schedule a technician to come to my house. Chris showed up at my house on time 4 hrs later to investigate the air conditioner problem. It took him approximately 30 minutes to diagnose and fix the problem. There was a broken piece of equipment called a capacitor. The bottom line is the problem is fixed and cool air was wafting inside my house in approximately 30 minutes. I certainly could not have asked for better service!”

“Interstate is a great company they are responsive and always do a great job for us. The Company takes care of whatever problem we may have as quickly efficiently and reasonably as they are able. You cant ask for more. Most times we get the same people who will come to do our work. In our case it’s normally Kevin for the heating and his Son for the cooling. They are a great duo both great guys and know our home our systems that are complex and they keep it all running really well with rare visits in between our normal twice yearly maintenance work. Both father and son and knowledgeable polite a pleasure to have in our home great with our dogs and everyone we have dealt with over the years at the company are responsive and personable. All their good work is really appreciated. We built our home about 7 years ago and I would recommend Interstate when designing your new home or maintaining your old home. To find a business these days that appreciate you and are responsive and know what they are doing are becoming a rare thing sadly. So thumbs up to everyone at Interstate and the great job they are doing!!
Thanks!”

Very pleased with my technician's knowledge, professionalism, politeness and attention to detail concerning the repair of my Carrier AC unit.

See you in Autumn for my Carrier furnace tune-up.”

I just wanted to drop you a quick note to say thanks for all of your efforts in getting us our new furnace and air conditioner—the installation crew did a fantastic job. I’ve shown a few people the installation and they were amazed at the neat, professional job that was done. Plus, the whole crew was very friendly and patient with me and my endless questions.
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 money we’ll save. We literally could not be happier with the system. I’m sure there are more exciting home improvements, but this necessity has given us the most benefit and a lot of enjoyment. I will highly recommend you and Interstate to anyone who’s in the market for new HVAC equipment, starting with my dad, who has a furnace and air conditioner that are nearly 20 years old. Thanks again.
-Pete
Your company recently installed a new Carrier® furnace and air conditioning system in our home. We were very pleased with the quality of service we received. From David, who oversaw the project, to the entire team helping with this installation, we were most impressed. Everyone was professional, knowledgeable, and extremely courteous, 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 R.
Good morning, David. I write this message to let you know how pleased we are with your service while having a new furnace and air conditioner installed in our home. Your quick response to our request for an estimate and recommendation, followed by a three-day turn-around on installation, was exceptional. Tod and Brett did a great job in installing the units, they were pleasant to work with, and did an excellent job cleaning up after they were done.
Our air conditioner is working great, and we are always ready to recommend your company to our neighbors. Keep up the great work and thanks so much for your outstanding service.
-Mike & Anne S.
We wanted to send a note to let you know how pleased we are with our new air conditioning. Our hydronic heat (a boiler) prevented us from having anything but window air conditioning units—until we met you at the home improvement show and you explained what your company could do. The entire process went very well and the vents in the ceiling look as though they’ve always been there. Your staff and electrician were great to work with and they cleaned up as they went along—a huge plus in my book! Our install was in early May and when the warm weather arrived—heaven! No struggling with window units, no taping windows, just comfort at the push of a button. Yours is definitely a company to trust. Thank you again!
-Fran & Thom
Dave, the new system is super quiet—I can hardly tell it’s on. Thanks for the great job.
-Steffen W.
I really appreciate your excellent personal service, especially coming to my house with the usage instructions after the equipment was installed. This is the reason we have recommended Interstate to two friends—one for a new air conditioner and furnace and the other for your maintenance services. In fact, we gave you and Interstate a perfect “10” on Carrier’s survey.
-Yang
We were very pleased with Interstate Heating, and just wanted you to know what reliable, efficient young men you have in your employ.
– Ron & Marilyn W.
Your installers were top notch and your company did everything they said they would. I have received rebates and was glad that your company made it so easy to get them. I will highly recommend your company to anyone I know who needs new heating or air-conditioning equipment.
-Tim H.
Our Carrier® air conditioning unit lasted for 34 years without service, which is quite remarkable. This experience, as well as high ratings by Consumer Reports, made the selection of another Carrier our first choice. We are looking forward to the efficiency of our new Carrier heating and cooling system. Interstate’s installation of these units was performed in a professional and timely manner.
-Jim & Marion K.
I have been a customer of Interstate for many, many years—I think I bought my first system from you in the late 80s or early 90s. You have an awesome company with awesome people working for you.
I especially wanted to compliment your team because I have called twice since last week’s installation and am so appreciative of all the people I have worked with—I hope they do not feel I am being a bother.
I have always recommended Interstate to anyone looking for heating or cooling solutions, and I just wanted to thank you and the entire Interstate group of people for being so good at what you do. Thank you so much and please let the people who worked on my systems in the past week know that.
-Anthony
Everything is good—the two men who were here were the most pleasant workers I have ever had come over. Thanks!!
-Mary
I just wanted to let you and Interstate Heating know that the crew you sent to do my furnace install did a fantastic job. They were very prompt and quick, did a professional job, and really seemed to be enjoying their work. On a scale of one to 10, I would give them a “10”. And this new furnace is really quiet—what a nice change compared to my old one.
