Came out same day and provided great service! Would highly recommend!
Amazing experience. My AC quit during a heat wave and he was able to come out and fix it that same day. He was very professional and knowledgable. He even alerted me to a gutter problem he noticed while fixing the AC unit! Thank you!
Ryan came out to my home for an estimate to replace my furnace . We planned on waiting a year cause we wanted to save up the funds. Ryan’s price came in very comparable with the competitors, only difference was, he did a temporary fix to get us thru the winter. Due to this kind act, we moved forward with our new furnace quicker than we thought and we knew ryan was the only person we wanted to work with. Highly recommend
I had been having trouble with our mini splits and I was referred to CDC HVAC by a mutual friend. Well, I’m so happy we found them! Ryan ( owner) was transparent the entire process regarding expectations, next steps, and pricing. He came out a few days after speaking with him. He was communicative & honest. When he got to the house to service the mini splits, he went the extra mile to really figure out what was causing the issue. He fixed our issue and got everything up and running! In the future, we will not hesitate to call CDC for future needs!! Thanks Ryan and Co!
We lost AC on one of the hottest summer days, Ryan came right out and fixed it! He’s very knowledgeable, with years of experience, reliable, and reasonable which is what you want! We are having him back for another job soon to help with our basement renovation. I highly recommend using CDC HVAC!
