HVAC reviews in Geneva, New York

Duane was professional and explained what was needed to replace my old furnace. He treated me with respect and as a valued customer. I felt I was getting a very good price for what Duane the furnace, labor and other items. He is the best..

Had a great experience and interaction with my technician. He walked me through all of the work he completed, including before and after photos. And reminded me about steps I could take on my own to help maintain optimal operation of my system, between service calls. Would highly recommend!!!

Interstate sent out Clark Kent, and like Superman, he saved the day!! Our gas fireplace wasn’t working and within 30 minutes he had it figured out and back running like a champ! I’d recommend Clark and Interstate to all my friends and family!

All interactions with the T-Mark team exceeded expectations. We are so satisfied with the timelines of getting our home warm again!

Fantastic service, technician was very professional and knowledgeable. Had our hear up and running. Would definitely use Interstate, Thank you Zoe..

Just had a service tech to the house. He was very knowledgeable and answered the MANY questions we threw at him. This is the first time we've used this company and we were happy with their customer service.

Our experience with Duane and his team at Interstate was simply amazing.They were timely and efficient. We talked about our needs and our options, and made the perfect choice, as we ended up with heat and air conditioning. We are totally loving our new system.

I called on a Friday morning and had someone there that afternoon to fix my father in laws furnace. Very friendly and super knowledgeable, will definitely be using services in the near future

I had no issues ordering the unit for cooling! It took less than forty eight hours to have them deliver and installed by the nicest guy! Great customer service and great people!!!!

Service technician was very professional and explained what he was doing. I was very pleased with Joe. I will call Interstate again when it is time for the next service on my furnace.

Very receptive to help with a heating issue even though was not a regular customer
Joey was the tech that came very good man and did much diagnostic work and determined the problem

Joey came with new thermostat and furnace is running great He is very knowledgeable about so many things to do with heating units I would ask for him again if ever needed and would call interstate for any heating or cooling needs Great company

Nathan Tim and Tony were professional and thorough. Explained what needed to be done and completed repairs and maintenance. They were great.

Kim was quick, thorough, friendly, and honest. He clearly described what he fixed, even inspected the whole heating system, and let me know what to keep an eye on in future. I learned a lot, too!

Initially, there were some problems with the install layout. But the company sent out more experienced staff who were able to work out the plan for the install. My mini split stopped working about four weeks after installing
. I didn’t know how to coordinate them in the mode setting on the remote.
A Very knowledgeable employee name John from marathon was very professional. He put on booties when he came in and was able to discuss how the system works and how the remote control works. said he would follow up with a written note to me .

Joey Marrocco was very professional and kind. He changed a sensor on my furnace and stayed to answer questions about my thermostat.
4 stars because of the difficulty I had calling in to the company over the weekend and getting emergency services.

I called for assistance to light my pilot light, The gentleman came over and began looking for issues from the start. He said there was black spots which were holes so he would not fire up my propane furnace. He stated this would cause leaks and he’s not gonna even test it.
I called for a second opinion from a separate company. They stated the black spots were simply flaking from the old furnace, not holes, and he was actually able to clean up all those black spots, and none of them were left. The new company, then lit the furnace and found no leaks during a combustion test and left.
It would seem Interstate Heating sent a salesman rather than a repairman to my house. 🤔

Great service! Really great people. Very on top of things and fantastic work! Very happy with the quality. Thanks!

Joey Marrocco was a great technician, Joey got right to work and was hands on and figured out the problem fast. He went above and beyond in the freezing cold snowy weather and got the job done on my mini split unit and got heat back up and running. I would recommend interstate heating to anyone in need of repair or install.

Duane (technician) really took the time to explain the new system and was in constant communication to see if there was anything else I needed or if I had any further questions. He responded immediately--after hours/weekends and helped with insurance requirements. He was super to work with and tried to make the process as easy as possible. He looks out for his customer.

Jamie, Seth and Justin we absolutely amazing, professional, polite and well knowledgeable Service Technicians that came to install our new Central Air system. They took the time to review the job, explain the details and then educate us. Jamie as the lead was very great with the guys he was professional he helped them to understand what they didn't and educate them if needed. He also took a after hours call from myself with questions and was nothing but professional and friendly!!! This team was amazing! Also at the office I met the head of Service who also walked me thru some of the setup prior to setup as the Sales rep Mike was professional and friendly but lacked the knowledge of the field and equipment specifics. Heather was also very helpful on a few calls and polite. My only con is that I believe Sales reps should go in the field with the techs to see what they do daily and understand the specifics about installing systems.

Just had a service call with the tech, Joey Marrocco. He was very knowledgeable about the heating and cooling for my trailer. He explained everything that needed to be done for us in a very calm and cool way!
Thank you for your service.
