A PG&E power surge fried my central A/C. As always, I called Dave to come to the rescue. He replaced the damaged part, checked the entire system and we were good to go. I always rely on Air Wolf to keep my HVAC in good order. read more

David is a great guy. He tried really hard to help me with a horrible situation with my insurance company. He knows a great deal about HVAC, I'd absolutely consider him a subject matter expert. He's reliable, trustworthy, and an all around great contractor who is exactly who you want to work on your home. read more

David De La Vega is Very Professional and good natured. He did the best he could with my horrible issue. The Heat wave started early July and the AC did not work with temps over 100. He returns calls, shows up when he says. He tended to details I believe most others would miss. My Mobile Home's HVAC is over 50 years old and needs replaced entirely. I had no clue except in the winter the heater made noise but did not work. The Inspector when I purchased, said the HVAC worked fine, which was not correct. David was honest about not being sure how long his repair would last, and a new system is needed for the long term. A good thing was The defunct heater segmen, the gas pilot was running for no reason given the heater did not work. He noticed and turned it off. It made a huge difference in my gas bill. He's good. Not inexpensive, but I believe he is fairly priced for the time he spent on my situation. read more

David at Air Wolf Energy Efficiency is amazing. He was the only person to call me back on a holiday weekend during a heat wave. He offered to come out same day, found the problem and fixed it. David was incredibly compassionate about a recent death in my family and the necessity of fixing the air conditioning quickly to allow my father's body to be kept at home per his wishes to be laid in state prior to his funeral. David worked with my brother and was incredibly generous in not overcharging when I was ready to pay anything he asked. Highly recommended and I will be using his company for all further air and heating needs. read more

David was recommended by a friend. So called and had an appointment set up to have my central Heating and Air Conditioning looked at as the heater was not igniting. David showed up on time check out my unit. Found a minor problem that he corrected. Also looked over my AC unit. He answered a dozen different questions that I had for him. Explaining how the system works etc. I am immensely satisfied with the service that was provided by David and Air Wolf. I highly recommend this company. Fair Honest and very helpful. Thank you Air Wolf C Parker Auburn Ca read more

Excellent service. Experienced, professional, timely and truly cares about their customers!

Air Wolf Energy provides great service, is very friendly, and takes the time to explain everything. Air Wolf has been out to my house twice in the last two years to make repairs on my H-vac system. The last time out he saved me a lot of money by cleaning a part rather than replacing it. I will definitely use them again. read more
