Get matched with top furnace / forced air heating system install or replace pros in Walnut Creek, CA

"To start, I put in for an emergency call to Freschi and was told they would call me 30 minutes before. They never called me back. Freschi sucks!!!I I also put in a request on HomeAdvisor on Thursday night and was given Global Warming Heating and Air as one of their verified contractors. I got a call at 7am from Rudy. I called back around 830am and we made an appointment for 1130am. He showed up at 1105am and quickly diagnosed the problem. He recommended replacing the furnace(which houses the blower assembly) due to the cost of repairs and its 17 year old condition. He didn t try to up sell me for an entire new system. He said my AC is working well so there s no need to replace it. I decided to replace the furnace and he said he d be back around 130pm. Rudy and his crew were back by 1pm. From the start of demo to it running again was less than 2 hours. Rudy s customer service is top notch!! From now on, I will only be calling Global Warming Heating and Air. I can t say enough good things about Rudy s business ethics and timeliness. A+++++"

"Gilbert Caceres from Perfect Star Heating did an excellent job of determining the issue with our old furnaces and corrected the problem in a professional and timely manner during the holidays. I wholeheartedly recommend him and Perfect Star Heating."

"Aire Systems of Campbell and Saratoga truly sets the standard for exceptional service in the HVAC industry. Alton, the owner, went above and beyond to ensure I understood every aspect of the process, from selecting the right system for my small home to navigating available rebate programs. His expertise and dedication to customer satisfaction stood out as he guided me through the rebates step by step, emphasizing how beneficial they are despite the effort required. What really impressed me was Alton’s commitment to follow through—he’s not just selling systems, he’s supporting his customers well beyond installation. Daniel, the team lead installer, was equally remarkable. Always punctual and professional, he demonstrated a level of care that extended beyond the job itself. He kept me informed daily, explaining what was being done, what to expect next, and how long it would take. Knowing I had to leave for work, Daniel kindly spent time with my dogs, making sure they felt at ease while he worked. It’s rare to find a company that combines technical expertise with such personal care. Aire Systems, with Alton and Daniel at the helm, earns my highest recommendation!"

"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!"

"Elite Heating and Air Conditioning replaced our HVAC system at our home. The cost of the system, including installation, was the best among several other quotes. Best of all the service they provided met and exceeded expectations. We are so happy we chose Elite for this big project, and we recommend that anyone needing heating or air service reach out to Elite. Thanks, guys! Sincerely, Eddie B."

"Appointment was scheduled between 8am-4pm. Waited all day for the tech (Jeremiah) to arrive. Then received a phone call a little after 3pm indicating they needed to reschedule for the next day almost at the last moment. Needless to say, we got off to a rocky start, but Jeremiah did finally show up around 5pm, isolated the problem in less then 5 minutes, showed me what to do and what not to do when changing batteries out of the thermostat, and pointed out which fuse had blown keeping the furnace from coming on. In conclusion, they made this right, I received a well-needed lesson on minor furnace maintenance, and was able to get the furnace working again. Would I hire this company again? Absolutely, and if you are having problems with your furnace, you might want to consider these people as well!"

"These guys are AMAZING! They replaced a furnace and overall I was VERY
IMPRESSED. Their prices were great, their service was 10/10 and overall
very professional and trustworthy. I rarely review, but I feel good
about recommending them because I know you will be in great hands.

"Alanis was prompt in their response to my request for our condenser replacement. We replaced our furnace 4 years ago, then our ac went out when it was 90° outside. John said it was over 30 years old so we decided to replace it. He gave us a great price on a 5 ton Bryant condenser. Best deal out of 3 other companies. The next morning, the team came out and were finished by noon when it started heating up. System works great! Thanks guys."

"They did a wonderful job and even checked on the furnace"
