I met with a member of their team that clearly explained everything and helped to design a solution that worked for my family at a fair price. The install team arrived on time, they were very polished, and did a technically excellent job. The system is working really well and the whole family is comfortable! Couldn’t have asked for more - I’ll be using Carroll Mechanical as my go to HVAC contractor from here on out."

Tech (Isak) was punctual, professional, and patient. They originally quoted me for the service and later on they found my system is still under warranty.. Which saved me a bunch of money. I have nothing but good things to say about the whole experience. I recommend them wholeheartedly and will definitely use them again."
