"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+++++"

"Dennis is a good guy and a professional. He showed up promptly on time. Analyzed the problem as my heater's thermostat failed. He had a replacement part, ready to go but it wasn't WiFi capable. I decided to get a smart thermostat from Best Buy and asked him to return to install it. He did and my furnace is heating my humble little house. Thank you Dennis, job well done."

"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."

"Absolutely the best HVAC company in the area. If you are looking for a company for your HVAC needs, look no further. It is superb in every aspect: customer service, onsite specialist who did the inspection and quoting, technicians who installed the system. Their price is extremely competitive, especially for the high end systems. I was shopping for a 80% 2-stage furnace but I ended up getting a Lennox 99% variable-speed furnace because the price was too good to pass. But it is money well spent. It is so quiet and powerful. I highly recommend Air Sharks. They actually put a smile on our faces."

"We did a major renovation in our house and replaced the old gas heating system. Bobby did a great job of installing the new heat-pump based central A/C unit. He picked the right unit for our house and installed it along with all the ducts. He's also easy to reach to for any questions or maintenance requests. We've been using the system over a year and it's running great."

"I had a new HVAC system installed in early November. There was some work from the installation of that new system that needed repair. I advised them of the issue and scheduled the work. They sent a technician out and he took care of it."

"The service provider was timely and professional! I plan to have them continue my seasonal maintenance going forward. I highly recommend them to anyone in need of AC repairs."

"Jim's Air Systems had the best value for my dollar. They supplied me with better equipment than they quoted for the same price. They completed the entire installation in about five hours. They protected my floors with tarps and were very careful to protect my walls as they moved equipment in and out. Josh, the son of the original Jim, was on the job working with the other two installers. They performed above my expectations. They left my home and yard as clean as if they had never been there. The new furnace is wonderful and is already saving me money on my P.G. & E. bill. I would recommend Jim's Air Systems unconditionally to anyone in need of a new furnace and AC system. This is a family business that has been supplying and installing systems since 1976. They take personal pride in doing an excellent job. They did not sell me anything that I did not need and provided me with a much cleaner and easier-to-service installation than my existing system. They are the best!"

"Ross was very helpful and patient with our project. We had a lot of questions about upgrading our panel and adding a sub panel for a hot tub and outdoor conduits. He was prompt with calling and texting and has been very responsive with getting the project moving from the start."
