Heating & Furnace Contractors in Mount Wilson, CA

"The tankless water heater installation at our Oakland home has been fantastic so far. We finally have enough hot water for the whole family without constantly waiting between showers. Dan completed the installation quickly and explained how everything worked before leaving."

"They did a very good job and I was very happy with their work. Their quote was great as well. This was for out business and we would highly recommend them. LA Canada ARCO"

"everything was perfec and clean"

"This HVAC company is honest and professional, definitely the one to hire. I had another company replace my A/C units last summer and level the furnace, but the system broke down after 6 months. There were several parts of the system that they failed to repair or even inform me about. Reese spent the time to give me a fair and accurate estimate, and even encouraged me to get other estimates before hiring them! Lance the installer came out to replace my old furnace and repair a few parts of the A/C system that had been slapped together, but he went above and beyond to expand my attic access, improve the drainage and bring the whole system up to code. The A/C and heating work great now, and my family and I feel safer knowing that Lance put in the extra time to carefully check everything."

"Outstanding. Duane is the best HVAC professional I've ever worked with. He thoroughly explained the HVAC process and standard yearly preventative maintenance requirements. He also gave me a quick tutorial about my particular A/C unit and explained how to spot any early signs of malfunction in order to prevent future expensive repairs. Top notch, highly recommended."
