"I HIGHLY RECOMMEND HVAC Superior Solutions Inc!! They came over to diagnose my AC problem on very short notice. I decided to get a whole new system and they took great care in all the details and worked overtime to get the job completed. I am very satisfied with the new system and with the great customer service."

"Excellent service from Hecomo. Technician did not try to push purchase of a new HVAC system even though there were major issues with our system, feel comfortable while talking with an advisor. Very knowledgeable, patiently, friendly and nice person, answer all my questions. Later on, we decided to replace the whole new system with fair price and wasn’t ripped off as others. Very professional and well trained technician. I will definitely use them again."

"The job went reasonably well. They completed it in a day and a half. The guys on site had a little trouble installing the high tech thermostat for the system, but their supervisor demonstrated real accountability when he showed up on a Saturday to make it right."

"Pat Ward has done two jobs for us...relocating our HVAC condenser and designing and installing a super cool custom overflow drain for our basement utility sink (so the sink won't flood out if the drain gets blocked when I'm doing laundry). He showed up when expected, he worked in a clean way, the results were clean and effective, and he was professional in every way. He also might be the nicest guy you'll ever meet. Thanks Pat!"

"Carroll Mechanical delivered a 10/10 experience, from start to finish. From the first call, the Carroll Mechanical team demonstrated that they were knowledgable, ethical, and customer-first. First, they offered to help me troubleshoot, and they gave me some great tips that allowed me to try and fix the problem myself before they made a service call. As a not-so-handy guy, I realized that I needed the pros, so I requested on-site help. They immediately offered to come over on the day and time most convenient for me, and they spent time with me walking through the pros/cons of different HVAC options. Ultimately, the team explained the pros/cons of different remediation options, offered me an extremely competitive quote, and was transparent all along the way. I moved forward with a system replacement, which they were able to accommodate the same week(!!). The Carroll Mechanical team was timely, detail-oriented, and respectful of my home, and the HVAC system was installed as expected."
