“My entire experiece with Chaves was excellent. We had problem with fernace in on cold morning and we called. They called back in a few hours and sent someone to examine the problem, they told us how to get by exsiting problems and backup options. On second day, they sent someone to evaluate the situation in details. the technician suggested to replace this 25 years old furnace with a more efficient one. Chaves provided a quotation within one day. We decided to move forward and installed the wonderful system within a few days. We are very happy about the price/performance of our new firnace, the process of the installation, communication thru the process, and friendly services.”

“Mike and Al replaced my furnace, installed a new central ac system, and also installed a new humidifier. These guys did an excellent job – my furnace was original to my home built in the 70's so it was somewhat of a tricky install – and they did an amazing job in a very timely fashion.
I highly recommend these guys!”

“Owner Manny Chaves managed to fit us into a packed schedule to come and get my Climatemaster geothermal heat pump running right after the Christmas holiday. Clearly a methodical guy who understands the way the entire system works and potential things that could go wrong- and our experience has been that this expertise is not always easy to find. Glad to be back up and running and glad to have Chaves HVAC in the contact list as a local Geothermal expert!”
