Heating & Furnace Contractors in Livermore, CA

"It was great working with Dream to Reality Remodeling Overall the experience was amazing. From start to finish it went smoothly. The final outcome was impressive. They Remodeled our kitchen and the before and after difference was out of this world."

"I got quotes from four contractors and Super Builders had the most reasonable price. It is usually not recommended to go with the lowest quote, but in this case it was great! The whole process was smooth and their contractors were very nice and they even helped some small fix ups around the house. 5 stars for Super Builders"

"We hired Grassrock Corporation to install new AC unit and replace the old ductwork in our house. We are very happy with our decision, as the company gave us the most reasonable quote for the work to be done out of many other HVAC companies we invited to estimate, and did the work fast, with minimum house life interruption, neatly, and competently. James, the owner was cordial and good-natured young man and gave us helpful recommendations to our HVAC system, as well as offered some additional items to improve the performance of heating and cooling."

"Very professional And Timely courteous with both installation and removal of old boiler I would recommend them to anyone."

"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+++++"

"They did a good job on checking my furnace and changing my air filters. The only issue was that they arrived three hours later than they had stated on the phone."

"Great experience with very professionals. From our very first meeting I felt confident that the job would be done efficiently. Very pleased and would highly recommend."

"Knowledgeable, courteous phone representative and technician. Willing to answer all my questions and provide multiple options. Same day service for a broken furnace."

"Very good communication, fast service. We have an old floor furnace that needed a part replacement with an update to current standards The estimator spent a good half hour identifying the problem and the solution, and explained it to us clearly. That cost was deducted when we had them fix the heater, which they did quickly and successfully. Very happy with the service, if we replace the furnace we will turn to them first."

"We had to upgrade our old furnace and AC so we decided to look around and call a couple companies to come and give us a quote. We decided to go with Smart heating and air, their prices were upfront and fair. We got our systems installed in a very professional manner. All the technicians wore masks, they used foot covers and put down cloths to protect our floors. After they installed they tested both ac and heater to make sure it was working. The cool thing about it is that we can control the temperature with our nest app without getting up with our phone. I love this bc I was always forgetting to turn off our system but now I can do it anywhere. I totally recommend this company. We will use them for any HVAC related concerns."

"My HVAC unit was 20 years old needed consistent repair, and my ducks where leaking. It was time for a new unit. I also wanted to relocate the condenser to improve my back yard space. I had gotten 4 quotes before someone referred me to http://www.aircmechanical.com/ Vitor was literally the first smart person to offer a quote. He suggested relocating the condenser to a side of the house and changing it to a suitcase type unit. He also came up with the creative solution of adding a 2nt inlet in another part of the house to reduce noise and improve airflow. The other contractors wanted to enlarge and or relocate the existing inlet which would have been an ugly mess. I now have an extremely efficient 2 stage unit installed correctly and he beat the other quotes. Entire product was completed in 2 days. I couldnâ t be happier."

"I highly recommend this company!!! He responded within minutes of my searching for a plumber. He came the next day and installed a new tankless water heater. He also found a faulty electrical outlet and repaired it as well. Quality workmanship. I will keep his number. His name was Harry."

"We had a new A/C put in on 7-19-19 and we had a bumpy start. The person who installed it didn’t notice wires were not plugged in up in the attic by the furnace. The house didn’t cool down for days. I called them back and Service champions made it right the very next day. Travis was courteous and friendly assessing our needs for our house, giving us a clear estimate, and Ben was thorough and friendly and reassuring when he fixed our problem for free when I called them back. I would also like to note that service champions has a live person on the phone 24/7. Perfect for emergencies. Give them a shot!"
