"Moore services my HVAC every six months. The crew that came out for my recent call, have been to my house before. Nice to see familiar faces. My main sewage drain clogged in front of my house at 4:50 pm. I called Moore and you’re team came out in 30 minutes. The crew had it unclogged at 5:40 pm. I couldn’t believe it. I was considering taking my family to a hotel. With that clog, staying in the house was not possible. You guys are awesome!!!"

"We had a totally broken HVAC system in our 30 year old house. They came in and fixed it in two days. The guys were very friendly and answered our questions. Our original salesperson was knowledgeable and respectful considering the state of our equipment at that time. Now we have heat for the rest of the Winter and AC for next year. Thank you!"

"Green Core Heating & Air did an excellent job installing our new gas furnace and completely replacing the ductwork. The owner communicated clearly throughout the entire process and was always quick to answer questions. The crew showed up on time, worked efficiently, and kept everything clean during the installation. Pricing was very fair compared to other quotes we received. I would definitely recommend them to anyone needing HVAC work."
