"Really fast and professional service when our HVAC broke in the peak of summer. Had it up and running in almost no time. My advice to first time homeowners like me in these cases is to always make sure you know what repairs and actions are being done. It'll help in regards to money."

"I cannot say enough good things about these guys. They got in contact with me very promptly. And when the tech came to my house to diagnosed the problem, he was extremely knowledgeable and professional. I called Paramount after dealing with another company the day before. The other company charged me a service fee just to diagnose the issue, actually a hefty fee, and would have charged me again to replace a "faulty" part, and another service fee to replace the part. Paramount came and diagnosed the issue, and resolved it without needing to replace anything. I basically paid around 15% of what I expected to pay to have my issue fixed by the first company. These guys saved me hundreds of dollars. It was great to deal with these guys, and I will definitely call them again when I have HVAC issues in the future."

"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."
