"I called Carroll Mechanical for an estimate on a new high efficiency heat pump system. 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."

"Moises, who is the owner is AMAZING!!! He took a smaller sized commercial job for me and found the issues right away, when several other contractors were not able to. He is very professional. His proposal was very throughout and his pricing is very competitive. He was able to schedule the repairs in less than a week from his initial visit without a service contract in place. I m a property manager and I plan to use him a lot more frequently for my residential and small commercial jobs. Excellent contractor!!!!"

"Mr. Viera was on time, I got a 30-45 min call ahead before his arrival, and he was promptly, he is very friendly, professional when he arrived, told me that not to worry, that the issues I was having with my AC that he was gonna take care of it, and he was also was gonna go beyond to make sure that my whole system, was not gonna fail as long as he thoroughly checked it, and let me know if there was anything else that needed to be taken care of it while he was here. So I definitely would hire this company again, and recommend it to anyone in the DMV area."

"Aprilaire A400 humidifier not working since installed. Two service techs from my regular HVAC company could not figure out what was wrong. Isak started at the HVAC control panel and followed the electrical circuit to the humidifier. He said I had an advanced HVAC unit and did not need to use the humidistat that came with the new humidifier. He removed it. He checked the humidifier hooked up directly to the HVAC control panel. Everything worked!! Isak then explained the control panel operation and how the float switches worked in the bottom of the humidifier to save water. Very Professional in every way. Highly recommended."

"They arrived as promised. Evaluated the problem correctly, and completed the repair promptly. My questions were answered courteously, useful advice and information were offered without being prompted and the cost was fair."
