Testimonials

On 6/19/2025 Rose Hollis had this to say:
I have been using Koalified since 2022 and have been extraordinarily happy!!! They have made small repairs to our furnace, installed a new Central Air Conditioner which is wonderful, yearly check ups on both HVAC units, both were very old, installed a new control panel on furnace. They’ve been so honest, pricing seems very fair (as we’ve been here before in other homes ), and the servicemen arrive with almost immediate availability, My husband and I know a bit about furnaces and a/c so we are able to provide enough info to help them with their diagnosis. It’s like a car, if you don’t give the repairman as much info as possible , even with today’s technology, it takes much needed direction out of the process. . I understand owners are veterans, which means a great deal to us, and is even better. Servicemen call ahead letting you know that they’re leaving their previous client. are so punctual, knowledgeable, efficient cheerful and grateful for the call! I have NEVER experience a company like this - so very great from beginning to end. They are fantastic! If the ratings were up to “10”, that would be my rating. GIVE THEM A TRY, YOU MIGHT BE AS HAPPY AS I AM!

On 6/18/2025 Tom Lipinski had this to say:
Had the furnace and air conditioning replaced today and I want to say what a professional and friendly install ! I have always been impressed with their quality and service!

On 5/29/2025 Kathy K had this to say:
Highly Recommend! I had to replace my whole system and the entire team went above and beyond to make that happen in the most economical and timely way possible. The advice they gave me was honest, transparent and invaluable. And the work they did to get the system installed was very efficient and completely professional. They were concerned about my property from the get-go, inside and out, and left it in great shape when they were finished. I feel very fortunate to have found this company when I moved into my new house last fall. Thanks guys for a job well done. Testimonial written by Kathy K on this site.

On 10/25/2024 Cathy R. had this to say:
They replaced my 30-year-old air conditioner. Price was good. I purchased a Coleman which is division of your that has a 10 year warranty on parts and labor. Most companies do not include labor in their warranties.

On 10/24/2024 Vicki M. had this to say:
Excellent service from the technician (Lionel) and communication regarding appointments was spot-on, I knew when the tech was on the way and when he was arriving. Punctual, fair prices and everything was explained thoroughly. I will recommend to friends.
