What Our Customers are Saying about us:

Read More
When it comes to servicing and repairing heating systems, they are the greatest technicians I've ever worked with. My parents had scheduled a boiler inspection. Only them, I guess, can fix things. The whole process from ordering to installing my new heating system was excellent. Thanks!
Read More
About 10 days ago we had to turn to The HVAC Service because of our heater. Jason, the technician, finished everything fast, and he said the machine is going to perform well from here on out. Instead of saying "no, sorry, I have to go," he complied with our request for a water heater inspection. Each and every detail was examined carefully. Thankfully, there was no need for any repairs. The whole thing has beyond our expectations, and we would recommend them.
Read More
To put it simply, they have talent. They are kind over the phone and provide a courtesy call 30 minutes before the technician is due to arrive. Chris stayed with us after he repaired our overheated furnace to ensure we understood how to maintain it properly and that his work would endure. Each and every one of the possible stars should be given to this service. Their tune-ups are excellent.
Read More
It was a catastrophe to move after checking the heating systems. The previous owners were concerned about possible boiler leaks and wanted to get them fixed quickly. With the assistance of The HVAC Service, we were able to. Dave showed on the same day for his scheduled visit. Dave was a pro at working with rusty pipes. Nothing; I'm hopeless when it comes to heating system repairs, and I've learned nothing from online tutorials. This company was referred to me when my tankless water heater started leaking. Their expert diagnosed the mineral deposit and fixed the problem effectively.
Read More
Wow, that's very great! They were devoted to selling a good furnace, not the most expensive one, when I called them to buy one. My relief upon learning that competent installation was included into the price was palpable. After arriving at our place, he had everything up and running in within 90 minutes. Thanx.
Read More
Professionals from The HVAC Service are always sent out swiftly to inspect and fix the heating systems (we have turned to this company thrice!). Chris fixed the broken limit switch on the furnace. Once he had inspected the furnace, he got to work with everything he needed. He changed out the machine's limit switch and cautioned us against neglecting it, saying that clogged filters would make further maintenance impossible. Good!
Read More
Without a doubt, I would recommend my friends and neighbors to use this service. Thank you for sending us a great technician like Derek. He is smart and acknowledgeable, and he quickly figured out why the Carrier boiler stopped heating water. He was quickly able to fix it. Awesome.
Read More
I've been using The HVAC Service for a couple of years and can say only good things about these guys. The service is always excellent. I told everyone about it, so now when my family or friends need help, they go to them. I can recommend this service because I believe in it.
Read More
I'd recommend Daniel, one of their techs. He is very good at what he does. He came right away when he got a phone call and fixed a Lennox AC. No questions asked, 5 points.
Read More
Excellent work! Andrey is in charge of the installation, and I want to thank him for being helpful and doing a good job. Everything was done quickly and easily. The HVAC Service is 100% the best.
Read More
The HVAC Service is my choice. I always go to their experts when I have a problem. A water heater should only be fixed or put in by people who know what they are doing. Dave caught a broken-down Trane boiler in time to keep my house from catching fire.
Read More
If you haven't talked to The HVAC Service yet, you should. Don't worry if you don't know which to choose yet. You're in the best place to get help. Last week, Derek tuned up my new Carrier boiler. I've been happy every time.
Read More
Technician Derek, thanks for doing a good job. My Lennox furnace is no longer making noise. This company has the best people working for it.
Read More
Thank you a lot. How many times have your people helped me with tech issues? Oh, countless, you are my personal magic wind. The last time Daniel fixed a Goodman furnace. While I was away, I didn't worry about my home because I knew it was fine.
Read More
This company is without a doubt the best when it comes to getting things done. You can be sure that the work will be done well and that the people who come to your house will do a good job. They only hire technicians who have gone to school and worked for a long time.
Read More
Excellent work! My water heater took a long time to heat up. My husband tried to fix it, but it didn't work. I was lucky to have The HVAC Service's number. The repairman came out the same day and quickly and easily fixed the Goodman water heater. We're both happy, me and my husband.
Read More
One of the wisest decisions I made was to purchase the humidifier from The HVAC Service. The HVAC Service. To begin with, their customer service representatives are always kind and helpful while responding to your questions. The guy who installed the system is very knowledgeable. My needs have been met to my complete satisfaction!
Read More
For my hotel company this company is the best - I just use their service to rent furnaces. When it comes to brands, they don't try to push on their customers and make them select one over another. Instead, they pay attention to what you want and go above and beyond. Exceptional professionalism and excellent customer service!
