TESTIMONIALS

 

"Fantastic Customer Service!  Best in the area by far.  Mike Card and his team have installed and serviced furnace and air conditioning untis in two houses for me.  Working with Card was a refreshing experience after dealing with other local vendors.  Mike's team shows up on time, are professional and go the extra mile to check out the whole system to be certain that everything is in working order.  Total quality work.  Mike's team is customer-focused, detail oriented and thorough.  Their prices are competitive and I don't hesitate to recommend them.  Thank you Lori and Mike!  It's nice to have a reliable HVAC company to call on!"


​Caroline D, Amherst NH

"I was very impressed, from the responsivenesss to my initial contact, a very quick estimate and excellent workmanship. Your crew was professional, courteous and very helpful. I appreciate that you worked with me to find an economical solution to our melted drain tray on the cooling coil. You guys did a great job!"

 

Steve, Wilton NH

 

"The workers were THE BEST and everything is working well! Wow! They were so neat, no dirt, dust or anything out of place! It was such a pleasure having you install our heat pump system. We can't think of one complaint. The fellows were so neat, even set the lawn removed for the AC back. It was a wonderful experience. Great family business! Thank you!!"

 

Bernie & Charlie K, Milford NH

 

"Excellent, polite, neat, thorough and knowledgeable are just a few of the words that describe what a delight it was to work with the entire family! Their timeliness and workmanship during the entire project made the decision to choose Card HVAC one of the smartest I have ever made! I would recommend them to anyone and everyone who is looking for a company they can trust to do what they say and stand by it!"

"Great experience. Mike has always been straight with us. He originally installed our furnace in '94 when he was with Delta Mechanical. We have tried other HVAC outfits, but when we 'found' Mike again, we were very glad to have him back. He can't retire because in our minds, there is no one else to do it right."

 

Ray & Lynne R, Milford NH

 

"Mike was excptional in his punctuality, knowledge, customer service and performance. I would highly recommend Mike to all my family and friends for all their heating & cooling needs."

 

Jeannie K, Milford NH

 

"More than exceeded my expectations. The area was cleaner than it was before you arrived. Great guys, very polite and friendly. Pat and I were more than pleased with your entire organization. You arrived when you said you would and worked very hard until it was complete. You concern over keeping the way to our cellar was appreciated. Since the only way to the cellar was through our kitchen we were very concerned about the floor. We didn't need to worry, drop cloths were put through every day. All you have to do is keep on doing what you're doing.  The friendliness and work ethic are a great asset."
