"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."

"I called Climate specialists for my heater that stopped working. Its been freezing lately so I needed to call someone ASAP. I called Climate Specialists and technician Dan came the very next day. He answered any questions i had and the pricing was fair. Will definitely be saving his number and keep him as my go to HVAC technician."

"This company never failed to impress me. I was truly blown away by the service I received from them as they addressed my HVAC air conditioning repair needs yesterday. The technician was intelligent, diligent, and expert about the service. I will highly recommend this company to everyone."

"This HVAC company is honest and professional, definitely the one to hire. I had another company replace my A/C units last summer and level the furnace, but the system broke down after 6 months. There were several parts of the system that they failed to repair or even inform me about. Reese spent the time to give me a fair and accurate estimate, and even encouraged me to get other estimates before hiring them! Lance the installer came out to replace my old furnace and repair a few parts of the A/C system that had been slapped together, but he went above and beyond to expand my attic access, improve the drainage and bring the whole system up to code. The A/C and heating work great now, and my family and I feel safer knowing that Lance put in the extra time to carefully check everything."

"Authority came out to service my tankless water heater, and I?m really impressed with the experience. Chris was the technician who handled everything, and he made sure to explain how the system works and what needed to be done. He performed a thorough cleaning, checked all the components, and made sure everything was running efficiently. He was professional, knowledgeable, and took the time to answer all my questions. My water heater is running like new again! I?m very happy with the service and will definitely call them again for any future needs. Highly recommend!"

"Fast Friendly and Affordable. Originally called to have the very old central AC unit to get recharged, within reason. Mike had listened to my concerns about the old central ac and heating unit. The ac wasnt blowing cold at all. So I let him know the parameters for that old ac unit and our budget to recharge it. He came by on 4-8-23, gave us the breakdown of the price of what he was going to do and explained what was going to be done, so no unexpected surprises. On 4-11-23, work was started and almost finished that day. Finished the job today 4-14-23. Highly professional of him to not charge us more for the unit installed because the replacement hvac one that we were originally quoted on was not in stock. New Central AC, furnace, water heater, coil and wi fi thermostat installed, and removed old pipes from a water heater unit no longer there. Will refer friends and neighbors who need work to be done fast, reliable, friendly and affordable. Thanks Mike"

"I work in the trades, so im no easy critic. My elderly motherâ s furnace went out, and was in need of repairs. Chris and his company were my choice, and let me tell you, was I impressed. Showed up same day within a few hours, diagnosed the issue, He presented multiple options to my mother, kept me updated along the way, and got the repair done SAME DAY!!! My mother was impressed with how clean he was, how much he cleaned after, and even scheduled a follow up for 6 months later to ensure the system is functioning as intended. Will definitely be using Chris for all my HVAC needs and referring him to everyone and anyone that asks!"

"Outstanding. Duane is the best HVAC professional I've ever worked with. He thoroughly explained the HVAC process and standard yearly preventative maintenance requirements. He also gave me a quick tutorial about my particular A/C unit and explained how to spot any early signs of malfunction in order to prevent future expensive repairs. Top notch, highly recommended."
