We install, repair & service all HVAC equipment and specialize in custom duct work. Our family started this company in 2003 after leaving a two-family owned & operated HVAC company started twenty-five years prior. The previous company had grown too large, and the personal attention to our customers was lost. Remembering why we started the business and with our strong foundation in the HVAC field,

we started this company with our customers as our top priority. We maintain a personal touch to our customers that only a family owned company can achieve. We maintain a business model geared towards fair pricing, honest work, and building lifelong relationships with our customers. Together father and son, with over 60 years of combined experience (along with our team of service professionals), service, repair, and replace all makes of HVAC equipment, while other family members answer phones, schedule calls, and maintain the company books. Our family loves what we do, and we hope to prove it to you.

Great review from Riley... "ACCH has been beyond incredible when it came to working on the AC in my house. We bought our house from sellers that told us the AC was recently installed, a couple weeks after moving in it was having issues. I called Atlantic because their sticker had been on the equipment. They were able to get someone out within a day or two since we were without full AC. We found out that the AC was not recently replaced and was almost 10 years old. They helped with cleaning the system to see if it would work before moving to a full replacement. When it stopped working again a few days later they got someone out as soon as possible. Leonard who walked me through exactly what he diagnosed step by step was extremely knowledgable, patient, and understanding to our situation. It turns out we did need to replace the whole system after all due to the evaporator coil starting to fail. Even though it was frustrating news to hear and tough to have such a big cost so soon after buying a house their Sales Rep Robert was extremely helpful walking through the costs and financing options. Even though I found some quotes that were a little cheaper from other companies I really felt like I could trust ACCH and that the investment was worth it. They were able to come out and complete the install in 1 day just a few days later. Avery and the installation team were friendly and informative through the whole installation. A couple of days after the install was complete we were still seeing some small performance issues. I called the office where Terri and Trish are always helpful and professional and they had someone come out later that day to take a look. Antonio quickly identified that since our house was built in the 40s and no additional return vent was added to the basement that it would quickly fix the remaining issues we were seeing. He came back a few days later and got it installed in just an hour and there was no added cost since it was a part of the original proposal. I feel confident that everything they have done so far has helped us get our new system up and running and plan on returning to them for any maintenance or issues going forward."
