At first, having to purchase a new furnace mere days before Christmas was a total pain, now that its in and I’ve lived with it, I can really tell a difference and I just love it!  Every room is consistent, warm and I can keep the thermostat lower that I did before but I’m warmer!  I also bought, a humidifier, which I’m just delighted with, you should know that the company I brought from was fabulous! Everyone was extremely nice and accommodating, wonderful experience.

Replaced bad ignitor and flam sensor on my heater.

I woke up Saturday morning to no heat! Yicks! I quickly checked Angies List and called a few providers. I like to stay local to my community so I am glad that Credible Air was working on a Saturday. Two other providers didn't bother to call back but Credible Air gave me a couple ideas to try and see if it may be that - check for a clogged filter, check the breaker. They said they would call back in an hour to see if any of that worked or not. They promptly called an hour later and set up an appointment for later in the afternoon. My filters were clogged but I couldn't find them anywhere. Not only did they come out to fix my heater but they brought out the exact filter I needed. Although I forgot to tell them I needed two they took the time to bring another filter by the following day. NOW THAT IS GOOD CUSTOMER SERVICE! They inspected my unit and found a faulty ignitor and sensor. They quickly and efficiently replaced the parts - as quickly as possible with the confinment of my space. They noticed part of my AC unit wasn't sitting properly thus it would cause water damage especially since my furnace and other units are located in my Attic. They corrected to problem without further changes. Not sure what they did other than change out an ignitor and sensore but my unit truely has more air flow now too. Credible Air Heating & Air Conditioning even called back later in the day to make sure everything was performed as I expected and if I needed anything further. Credible Air Heating & Air Conditioning far exceeded my expectations with the customer service and attention to detail!! Looking forward to having them continue to service my heating and cooling needs!

We called credible heating because our furnace wasn't staying on. Mike came in and tried everything to fix the furnace before replacing any parts. He went out of his way to try not to replace parts and when he figured out he needed a new furnace control board he found a used part, drove down to Littleton to pick it up and saved us a TON of money. On top all that this was done on Saturday!!

After looking for weeks for a company we could trust and having an estimate done by a larger company that made me very nervous, we are SO HAPPY we called Mike and Teresa at Credible Heating. Very sweet, honest and reliable people.
