Ralph and the team of men that came to replace my oil burner furnace and central air were amazing! They were polite and respectful of my home, they cleaned up the area they worked in. Everything went exactly how Ralph said it would no surprises. I would definitely recommend using this company !

Honestly one of the best HVAC companies out there. Super friendly and reasonable. Great customer service, turnaround time was efficient and they took care of everything!

On the hottest day of July I woke up to find half my house did not have AC. A tech was there in just a few hours and fixed the problem quickly. I am so grateful that we were able to sleep in a cool bedroom that night.

Ben was great! I love this company they are very honest and the work is impeccable! I had other companies come in and tell me I needed a whole new unit well mine has been running for the last 6 years

Donna M.
Thank you for fixing our AC so quickly last week. We really can’t say enough good things about this company. We first called Frosty years ago when our AC stopped working and another company told us we needed a whole new system. Frosty repaired it, and we’ve been happy customers ever since.

When I rate Frosty, I am rating 18 years of amazing service and experiences. First they are so polite and respectful and always answer the phone, thank you Vickie, Jon and Lauren. The techs, Terry, Kyle, George, Brandon ect. are all very professional and honest. Ralph has been very helpful and patient with tech questions. They are a top notch company, and they are competitive with pricing, thank you for so many years of great service!!

I have a PTAC wall unit which broke at the end of last summer and I was having so much trouble finding anyone to help me with this type of AC until I was referred to Frosty. Steve replaced my AC unit just in the nick of time before the temps hit 95. They were timely, helpful and professional and all for a very reasonable price! Thank you Steve and Frosty Refrigeration Co!

Kyle services my HVAV. Excellent service maintenance, professional and best customer service! I have used frosty for over 25 years! Highly recommend Frosty services!!

Elizabeth B.
Our central air failed yesterday, just ahead of an oncoming East Coast heatwave. We called Frosty the first thing this morning and they were able to replace our failed capacitator within four hours. I first used Frosty some 25 years ago. . .

Prompt, professional and fair pricing. No worries when they arrive at your home. I have dealt with Frosty for many years. They maintain my four Mitsubishi units.

Gary H.
We needed a humidifer installed to prevent damage to our hardwood floors in the winter. We went with Frosty Refrigeration Co. We couldn't be happier with the assistance provided when deciding what unit to purchase and the installation of our new humidifier. The attention to detail and perfection are second to none! I would definitely recommend them for your next heat and air requirement. Thanks again!

Randall K.
Can quickly get appointment. Super professional staff and fair pricing. You definitely get the family owned business vibe which I prefer. Highly recommend - thanks Frosty!

Cool there very professional

Bill B.
Great service! Our technician, Terry, was very professional and helpful. Diagnosed the problem quickly and was able to fix it in no time (even gave me tips to help run our HVAC more efficiently). Very reasonably priced too! Anytime you need HVAC help, this is who you need to call. I will use them again in the future.

Alex V.
Never before have I given someone $800 and received nothing in return. Until I called Frosty. The rep was a good guy... which explains the only star. I couldn't have been more disappointed. Pretty sure i was just robbed.

C. P.
I engaged for servics and while we did not come to an agreeable conclusion on solving my mechanical issue, they were more than happy to work with me and didn't bill, so I really appreciated their customer service and willingness to communicate.

Hugh G.
Used them for AC 2 years ago and furnace this week Both times they could have told me to replace the unit but recommended a fix that was far less expensive. AC has been humming for last two years and furnace is cranking There was a scheduling snafu along the way but it was just bad timing. Wont hesitate to use them again or recommend them to others It is clearly a small family business so I am happy to support them

Tim C.
Air conditioning stopped. I called at 6:30 am this morning, 7:10 am John showed up and around 7:25 am the capacitor was replaced and I had A/C back! Now that is fantastic service! I am so glad I have been with Frosty for years!!!

Neil M.
Great people and very fair and friendly.
