"Rick (Ricardo Mora), the owner of American Heating & Air, came to my house to look at a very old gas wall heater and give me an estimate. I was having a problem with it turning on automatically from the thermostat but not always turning off. Another company had refused to even look at it because of its age and told me I had no option other than replacing it, which is not something I can afford to do at this time. Rick not only looked at the heater, and figured out a couple of possible reasons why it didn't always turn off, but he actually disassembled the whole thing to inspect the inside of the furnace and make sure it didn't have any cracks or holes in it, and then put everything back together again. He adjusted the air intake and gas pressure and inspected and fixed the thermostat which had loose screws. Lastly he looked at another old wall heater identical to this one and secured the front panel which was loose. Now the old furnace is working just fine and he saved me thousands of dollars of expense. I also now know more about the inner anatomy of a gas wall heater and how it works than I ever wanted to know! I am extremely grateful for his help and highly recommend his company. Rick is knowledgeable, courteous, friendly, punctual, and generous with his time. He went way beyond the call of duty to help me out. These old heaters won't last forever and I would have no qualms about hiring this company to repair or replace them. Besides, I like to support small businesses and locally owned and operated companies."

"I cannot recommend Climate Services Heating and A/C strongly enough. We asked Sean to come out, inspect our system and give recommendations. His knowledge, expertise and demeanor were clearly evident. Discussions were comfortable, no pressure and Sean took the time to answer all questions. His bid was very competitive and we felt comfortable moving forward with the project. He was accurate with time and costs. Sean's crew was exceptional; friendly, knowledgeable and trustworthy. Sean was available by phone or text, prompt with updates, and very clear with communications. We are very happy with the quality of the work!"

"Green Core HVAC was awesome to work with! The team did a great job helping us pick the perfect AC unit for our home. They showed up on time, got the new AC installed quickly, and left the place spotless. Our house is cooler and more comfortable than it’s ever been. You can tell these guys really care about doing a great job. I’d 100% recommend Green Core to anyone needing AC work. Super professional, super friendly, and they really know what they’re doing!"

"Juan and his team were top tier professional. From the initial consultation to the hvac installation, they handled everything with care. Juan was so thorough answering my questions, the install was done in time, and everything was to spec. When I contacted him with an issue after install, him and his business partner came to take care of things immediately. I wouldn’t hesitate to recommend them in a heartbeat. So grateful for the work they did with removing our furnace and installing a split unit heat pump. Thank you Juan! "
