Best heating and air conditioning pros near Castro Valley, CA

"Of all the people I've had work on my home renovation in the last year, these guys were my favorite. Prompt, professional, honest, and reliable. When Duke came to give us the estimate, my 2 year old daughter wanted to give him a hug before he left which is unprecedented. That pretty much sealed the deal for us. They were also far and away the most reasonable quote we got. Even a friend quoted us $1500 more for less work. The installers were on time and knew their stuff. The install work is top notch as well. Everything in place and looks well put together. I highly recommend them to anyone looking for HVAC work."

"Smart Heating and Air Conditioning was the most professional, friendly, and knowledgeable company I’ve worked with. From our first contact, we felt like we were working with family. Our furnace went out and the techs and installers were all so amazing with keeping us all informed, especially Susie who works in the office. But what really showed me how great this company was, is that they saw our handle to our screen door wasn’t functioning and they were so kind to offer to fix the issue. They fixed it in 5 mins. You don’t see this type of generosity anymore, so we appreciate that! Our furnace and air were replaced for a great price and we couldn’t be happier. I would highly recommend this company for your heating and conditioning needs!"

"Excellent service just had a new air conditioner installed with new ducting Rudy and team saved the day. Also serviced my old heater at no extra cost will definitely be calling them back to install my heater in December!"

"Santiago was great to work with and done an amazing job installing a new heat pump system. Honest and competitive pricing, very clean job and took care of hauling the old system away as well. 100% recommended for all your HVAC needs."

"Air Sharks are very professional and I think they did a good job on installing HP HVAC in our property."

"Javid was helpful, polite, and thorough."

"Excellent installation On time, knowledgeable and courteous Would absolutely use them again My technician was Alan Orozco"

"Albert Nahman PHC installed new AC and Furnace for my house. I like them for several reasons -- 1. At first Tom explained in detail what equipment I need and how they work, and gave me a reasonable and detailed quote at end of the visit. 2. They offer interest free finance. 3. I got free upgrade for furnace when the original quoted is not available. 4. Their installer did good job, and cleaned up afterward. I highly recommend this company."

"The technician called me right away and was very helpful. The reason why I didn’t hire him was because the part for my stove has been discontinued, so I will have to buy a new one."

"These guys are just excellent! I made a few mistakes before I got lucky to find New Millennium HVAC. They were professional from the beginning to the end. Jose did a thorough job, cleaning the dryer vent. It was not a straightforward issue and I was afraid that we’d have to open the wall to cure the blockage. However, Jose was able to fix it. He’s an experienced professional excellent at his job, trustworthy and overall great to deal with. I’m a happy customer for years now and will rely on these guys for any HVAC related issues."
