"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!!!"

"Matt was wonderful in my home when my furnace was not working. We came to the conclusion that it was time to replace my furnace. Matt gave me plenty of options to fit with my budget and he had a quick install day. The Installers were very profesional and at the end, they explained what was done and how my new system works and got my thermostat scheduled. I recommend McDonald home solutions for any repair or replacement need!"

"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."

"It went very well; the thorough HVAC system checkup revealed some questionable component that were best suggested to be replace with new ones. I am not confident that my HVAC system is set for more that good performance going forward. I appreciated the non-pressured advice and suggestions in coming to my decisions. Thank you, Joaquin Ortiz."

"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!"
