Frontline Comfort Systems

Installed a new a/c and furnace in one of my properties, did a fantastic job! Updated: Used Ross again for a repair to my home A/C system and couldn't be happier, he explained what he was doing throughout the diagnosis process, pinpointed the issue and resolved and also informed me of other small items that needed attention by me and explained what to do to get them resolved. 10/10 again!

I wish I could speak highly enough about the service Ross provided. It seems that whatever I say about it, it wouldn't be good enough. Be he is extremely professional and an expert in the knowledge of this field. I am overly impressed by his passion to help people the best that he can.

When I called Ross at Frontline Comfort Systems he came right over to my rental property and had the problem resolved promptly. Since it was one of the hottest days of the summer, my tenant and I were very pleased with the service.

I contact landlord and after they contacted Ross he arrived very quickly was really friendly and helpful. He took the time to check the system fully and also gave tips on helping getting through the summer with our dinosaur of a AC system. He also kept the landlord informed and handled everything with them even being out of state this being extremely helpful and hassle free for myself!! A+ Work!

Thorough, friendly, communicative. Our new go-to for all things HVAC

Amazing experience with frontline comfort systems. They installed a ductless mini split I had already bought about a year ago and they did it for an amazing price. Will definitely be using them to service my mini split in the future!

I highly recommend Frontline Comfort Systems. Ross was very professional and did a wonderful job on my A/C unit.

Alec arrived on time and was very professional. He took the time to explain anything and everything to me so I knew what was going on. He fixed my system so it is running at peak efficiency. I would use and recommend frontline comfort systems to anyone.

I got my AC and furnace checked by Ross Kupac from Frontline comfort systems. He is very down to earth and very approachable. I was able to set up an appointment and he was kind enough to accommodate me based on my convenience. He came to inspect the HVAC and furnace for the new home I was buying. He was very thorough and did a detailed examination of the furnace, wiring, ducts, ducts flow and quality of the install. He also checked my air condition thoroughly. He has lots of high tech gadgets which he uses to check the measurements and functioning from the gadgets and through a phone app. He showed me the readings and explained me the findings during the inspection process. I have used many AC technicians in the past but he was the best among all of them I have encountered. He also had a infra-red camera which we were able to use as the Home inspector who was inspecting my home at the same time was concerned that a certain part of the attic was not well insulated. Luckily that infrared equipment measured the temperature which was even across which helped resolve the concern.
There was no sales pressure or pitch during his time. He never rushed and was just focused on identifying if there are any are any problems. He even explained how to get the best performance out of my system and how to avoid costly repairs in the future. Ross was extremely knowledgeable and has a lot of experience so he knew exactly what to look for. He knows his stuff very well as he has been in the business for many years. You can feel the passion he has towards his work when u interact with him. I was so impressed with him that I have asked him to tune up my 2 air conditioners at my current house I am living. If you are looking for a someone to check your HVAC system I would definitely give him a chance .I will definitely hire him again in a heartbeat.

Outstanding company! We had our AC broke on Friday, called them in afternoon and in an hour they were already at our place! Since the AC (a very old unit) went beyond repair they had a new unit delivered and installed the same day and really saved us because you have to have your AC in Oklahoma Summer. We are so very grateful, you, guys, rock!!
