No heat on Sunday morning. House temperature 50 degrees. We called several places and Mike Card came out immediately to see our furnace. Mike quickly determined that the draft inducer fan was not working. Mike had to order the part. He kept us up to date on the status on when the part would arrive and when he would be here to install. He is both professional and experienced. We will be using your services again.

Card Heating installed an HVAC system a few yrs back, great service, quality all the way. Didn't hesitate to contract them for a propane heating system for my house [woodstove is taking a backseat]. They delivered a quality job once again. My thanks to Mike, Lori and the boys and my recommendation to anyone in need of their service

Customer Testimonials

"Very professional and neater than expected. Extremely polite technicians. I am impressed and that is not the norm for me. You have exceeded my highest expectations. The rain made it difficult to keep from making a mess going in and out, but you limited it. The booties are cute. Keep the family atmosphere. It shows how much you care. Your price was fair and I would not hesitate to utilize your services again. You can add me to the list that prompted me to call you in the first place!"

"Card totally exceeded our expectations. We had an issue Saturday. We called Card and other places. Card was the only one that would come out on Sunday during their busy schedule to see us. Mike came out on a Sunday to see our furnace ASAP. Mike noticed that a fan was not working and the cause of our carbon monoxide issue. He took care of it. Very much appreciated. Best technicians I have seen yet, friendly and welcoming. They were able to get our furnace in ASAP due to my little girl being born. They also noticed an issue and fixed it without issue. This may have saved our lives. The price was on target, if not better than everyone else. Mike went over and beyond our expectations. There was no sugar coating, just nothing but honest work done and great workmanship! Thus far Card really stands out above the rest. A total first class business. I cannot think of anything to make it better. We wish Card Heating & Cooling the best in their business. We will be using your services again. Thank you again Mike and Lori for everything.

"Thank you for installing my new heat and A/C system. You all were very helpful to work with and made it a smooth and easy process for me. I felt comfortable working with you all. Thank you. Your company has been a blessing and it's nice to know you are right down the road. Thank you again."

" From the first phone call to Lori, conversations with Mike about equipment and scheduling, to the day of installation with Mike, Steve and Dave, you have all been wonderful to work with! I felt confident in going ahead with AC because I knew I was working with wonderful, knowledgeable, courteous, skilled people. Your patience in explaining things, answering and re-answering my questions, was much appreciated. You treated my home with care and respect. I am so pleased and grateful for your wonderful, professional service. Your work was neat, clean and so efficiently and quietly done. Your excellent workmanship exceeded my expectations."

We have used Card Heating & Cooling for a few projects. They initially put in a Harmon forced hot air pellet furnace. They were competitive on the price and we have been very happy with the level of service and the work that they have done. Most recently they are installing a whole house humidifier. It is a local family business and I have enjoyed my interactions with them all!

These folks are excellent! I just moved to the area, and have a forced hot air furnace in the new place. This morning the pilot was out, and I could not figure out how to relight it from the instructions.
I called Card Heating and Cooling, and they sent out a technician within a half hour. The technician got the furnace running again and explained what he was doing, and how the thing works.
Very professional, courteous, quick.
I would highly recommend Card Heating and Cooling!
I am keeping their phone number handy for any future issues.

Card is fantastic - routine cleaning/maintenance calls have been terrific. They do a great job of explaining everything for those us who are not technically inclined. Earlier this year we needed a service call for a broken gas valve on our boiler -- they came out quickly, were able to get hold of a part and come back later the same day. Super service, super nice. Highly recommend calling Card!
