After being without heating for over a month, I recently had Connolly install a new heat pump and furnace, and the entire process was exceptional from start to finish. The technician, Brian, who came to my home first was knowledgeable, patient, and clearly explained my options without any pressure. The installation was scheduled quickly, and the installers, JT and Justin, handled the unexpected challenges in my older home with professionalism and efficiency. They were respectful of my home, cleaned up thoroughly, and were friendly and easy to communicate with. While it's too soon to comment on long-term performance, the system is running well so far, and I'm grateful to have reliable heat again. I would highly recommend Connolly and their team.
I have nothing but praise for Connolly Heating and Air. They installed our HVAC system in 2024 and did an outstanding job - offering fair prices, excellent workmanship, and prompt service. When our water heater failed early one Monday morning, I reached out to them, not even realizing they handled water heaters. But they do - both tank and tankless. JT from Connolly was at my home by noon the same day and had the new water heater beautifully installed within 90 minutes. He was professional, friendly, and highly efficient. Connolly has consistently come through for us, and I strongly recommend supporting this trustworthy, honest, and fair family-owned business.
I've interacted with two technicians for separate issues, and both have been polite, professional, and clearly well-trained. The office staff is also friendly and responsive. Overall, the business seems highly organized and lives up to its reputation as a 5-star service provider.
Connolly stands out in terms of service and customer relations. The initial analysis and troubleshooting was handled by Chris, Brian provided an estimate and thoroughly explained the options, and Grayson performed the installation. Each of these individuals was an excellent and thorough communicator, completed their work seamlessly, and left no trace of having been there. As a small business owner myself, I recognize how employees can reflect on the overall organization, and these gentlemen demonstrate that Connolly is a well-run company with admirable top-down management and no weak links.
We have been Connolly customers for 10 years, with a twice-yearly service contract. This past week, we had our entire HVAC system replaced, and the crew, including Nick and Justin, was great. They were well-trained, professional, and polite. I highly recommend this company, as their team delivers outstanding service.
