"The repairman was professional, courteous, efficient, and friendly. We called for emergency help as the heater failed to come on, on a cold Sunday. He arrived within an hour. He quickly identified and repaired the issue. I recommend their service to all."

"I cannot say enough of the service, expertise & care of At Your Service. You couldn’t ask for a nicer or a better bunch of guys/team for all your HVAC needs & servicing. I contacted AYS in 2025 for a 2nd opinion of my 20-plus year old system. Jason from AYS arrived the next day & spent several hours inspecting & analyzing my unit. Bad news...it was shot. They could do minor repairs to keep it running as long as possible but I needed a new system. As my finances were tight, I approved the repairs. Those repairs took me through our deep freeze winter & the 100 degree temps of 2026 but she just finally quit. Again, I called AYS & Jason arrived the next day to inspect my unit. He gave me the bad news & offered 3 estimates for a new system. I chose the mid-line Bosh. Their installer, Tommy & his helper, arrived the next morning at 8:45 & worked non-stop until 4:00. I want to personally thank all the guys at AYS & let them know how very much I appreciate them for the kindness, concern & mo"

"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."

"Our heat came back on and therefore we didn't need the service at this time. However, they called us right away and were willing to come out on a Saturday to at least look at the problem. Professional Service."

"Brandon Brock arrived at my home this evening. He is very relatable with a keen sense of professionalism for the services he provide. I now understand how to properly clean my air filter and operate my nest thermostat. I still operate sort of old school but he encouraged me to utilized the nest app to help manage the temperature of my home. Most people use jargons, or acronym when explaining techniques, but Brandon was very patient with me and did not mind explaining anything more than once. It was a pleasure to meet him and started my weekend off in a good way."
