Because comfort is not just about summer cooling, our team also provides heating and air conditioning support for year-round performance. We take time to inspect systems carefully, explain what we find in simple terms, and recommend work that supports practical long-term comfort instead of quick temporary relief alone.

I upgraded my old Comfort Maker Carrier HVAC system to a new Carrier Infinity 21 system that included a new compressor, furnace/blower, coil, and the box exchange system. The installation crew did a FANTASTIC job! It took them most of the day but there was a lot of work crawling around in my attic. The cleaned everything up nicely and demonstrated the new thermostat. In the first night we noticed the unit was QUIET being right next to the primary bedroom. And the humidly control feature is welcomed! I did compare prices and it was basically tied for the lower pricing with some coming in $7k higher for the same system.

Joseph came to find out what was clogging our mainline and was very attentive detailed throughout the process. He did the work, but let me know what was going on along the way. I also have to mention Daniel who set up the appt over the phone too who was kind and got things set up quickly. These guys are always professional and do a great job getting to the solution,

I was dreading having to have my AC units replaced, but they were old and needed to be replaced. I was so pleased with Casa Mechanical. From the estimate and scheduling by David, to the installation by Gus and his crew, everything went smoothly and was right on schedule. I highly recommend this company, they are very professional, competent, and fairly priced.

Dennis Willis of Casa Mechanical was outstanding. He is a sales person who provided me with a reasonable price on my air conditioning system. He was easy to reach by phone or email. The repair went well and he even gave me a discount because of a delay getting a new part. He is an excellent representative of Casa Mechanical.
