"The tankless water heater installation at our Oakland home has been fantastic so far. We finally have enough hot water for the whole family without constantly waiting between showers. Dan completed the installation quickly and explained how everything worked before leaving."

"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+++++"

"Edgar is very detailed, respectful, professional with very good customer service! He showed up on time and completed the electric panel change sooner than expected! I have already referred him to my cross the street neighbor, Diane. Hopefully she will reach out soon for an estimate to change out her electrical panel too. Thank you ð ð"

"Elsy ( I believe she was the plumber from your company via Angi) arrived as scheduled, on Saturday, 09/28/2024. She attempted to repair my garbage disposal unit but was unable to do so as the unit's wiring was worn out. I advised the unit is 40 yrs old. She recommended to purchase a new one. We made a trip together to the local Home Depot store and I purchased the same brand s she recommended. She installed it in record time (within the 2.5 hrs) and completed the job. She also cleaned the work space and carried the old one to my recycling bin. Very satisfied with her work. Also, I want to know if I will receive a billing statement for my records? Thank you for your time & assistance."

"David was super helpful in looking at my Trane furnace and making all of the recommended adjustments. I especially appreciated the timexhextook to assess the health of the heater and suggestions for making some changes to get cleaner air. Also what to expect in the next few years. Bragg has been a reliable partner for my heating and and water heater"

"I have an old floor furnace that needed to meet PGE standards before gas could be turned back on. He insured that it was and re established gas flow. Hardly anyone would touch it and I was without it for over 2 years. Not only did Matt fix it within an hour, but also restored electrical power in my garage in a separate issue. Highly recommended. Not cheap, but if you want quality, Kazen HVAC is a name you can trust to get it done right in a most expeditious manner."
