Top Heating & Furnace Contractors in Castro Valley, CA

"We had the batts insulation installed in 2021. As well as the eco friendly radiant barrier which was suggested after researching we went with it. Wonderful recommendation from Attic Pros. Helps keep our home cooler in hot w weather as well as warmer in cold. The service comes with a warranty for Rat proofing. Recently we heard some potential rat noises from the attic. I called Attic Pros and was set up with an appointment for a technician to come and re check the work an seal off any potential areas of entry. They must have sent their best technician not only was he completely thorough as far as inspecting previous work and repairing anything that needed. He was very informative and courteous. We feel fortunate to have had Said sent to our home to do the work. As of now I couldnâ t me more pleased. If ever we need a service from attic pros. We will definitely request Said"

"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."

"After being told by other companies that I needed to replace my 80-year-old gravity furnace (to the tune of $20, 000 I did not have), I finally called Empire. I know that old machines are simple with few parts and no electronics, so I quickly learned that few people know how to REPAIR not just install. They do both. Pavel has studied heating repair for over 2 years in addition to his practical experience. He came to SF within 24 hours and even returned without grumbling when I got stuck in a dog emergency. He was polite, efficient, was able to diagnose and already had all the parts to do the fix immediately. Heat pronto! He put everything back in place and charged a fair price. When I am ready to replace my furnace and water heater, based on attitude and workmanship, I will definitely use them. I had done homework on new furnaces, and the Bryant brand heater (same owner as Carrier) they install are among the highest rated; well beyond the Lennox partnered with Costco. As a senior, a woman of color and homeowner, I have been burned many times. If I realized Empire was around I could have been securely toasty months ago. Thank you, Pavel."

"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+++++"

"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."

"I needed my old wall heater removed and they installed ducts and vents and the whole system. I was worried about any potential mess but that was unwarranted. They were so clean and neat, professional, courteous and easy to work with. They explained everything they were doing and showed my how to program my new thermostat. I'm very happy with Raul and his crew and highly recommend them."

"Thank you Eric for getting me in your schedule so quickly, being on time and getting my heater working! You did a great job fixing my wall heater at a reasonable price and I now don’t have to shiver the rest of the winter. Most others I have had come over have tried to convince me into getting central heating as my only option, but you were able to make my wall heater work again (and quickly). The best part of this experience was how professional, courteous & knowledgeable you were. I will definitely work with you guys again!"

"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!"

"I called Big Blue to repair my water heater which wouldn't relight, and was very impressed with the professionalism of Technician Nathan Jones. More than on time, Nate arrived and contacted me a half hour early. Fully prepared to replace my flooded out burner, Nate attempted to relight my pilot one more time, and it worked. He didnt try to upsell me and convince me to replace the burner anyway. Instead he gave me an estimate to replace the burner, made some recommendations for other areas of improvement, such as a sump pump to avoid potential flooding again, and gave me an estimate for that. Best of all, he didn't charge me for the simple fix, and instead used the service call as a complimentary job estimate and quotation. Awesome! Thanks Nate, for the excellent service! I will definitely call upon Big Blue again for any future plumbing needs, and I would highly recommend Nate to anyone for service."
