"Very well....signed up for their ongoing service for air, heat and plumbing."

"If I could give Cencal 10 stars - or 20 - I would! This is an ethical, compassionate, caring company owned and staffed by people who act out the company's ethos. Five years ago, when we needed a new dualpac in the middle of a cold winter, we shopped, and then chose Cencal for its responsiveness, clear information, and very competitive pricing. The installation went like a dream, and the service techs spent an entire morning at our home ensuring everything was working better than perfectly. The unit was under contract for a couple of years, and we decided to continue the contract when the "free" servicing expired. So worth the money for the peace of mind knowing our investment is being cared for by responsible reliable folks. I don't have a favorite tech: I appreciate all of them! They show up on time for appointments, and are universally businesslike and friendly. Thank you, Cencal, for making me comfortable in my home. (I'm not mentioning costs because I'm sure they're variable, but I'm on a fixed income and the service is affordable.)"

"Great now it cool. Same day service with a smile!"

"Jim with North Alabama Technical Services removed some items from my computer so that I could send emails and attend to items I needed to address that day. As planned, the next day he thoroughly cleaned my computer, he also made helpful suggestions while working on my computer. I would call him again if needed and I thought the fee was reasonable."

"Had Tim out and his guys to replace and move my system. Moved all my duct work from under the house to above the house I hated having the vent on the floor! Also moved my system from a closet in my kitchen to the attic which gave me more space to expand my pantry! The guys were all polite and would clean everything after their work day! They did a great job with all the work! Would definitely recommend Tim and his team!"

"We recently had Mega Power Electric Inc install a solar system and panels. The President and provided excellent communication all the way through the process. He even met with us after installation to explain the almost incomprehensible PG&E bill. Although not the least expensive bid, his was competitive and I felt he was as interested in educating me about solar and the various types of panels and inverter systems as he was in selling a system. He demonstrated how the array of panels would meet our energy needs and as opposed to some of the other companies, wasn't selling us more than we needed. We are very satisfied with our solar system and I highly recommended Mega Power Electric Inc."

"Exceptional product and service, Long's Air Heating and Cooling put in a system that is more effective and efficient for my home than was installed previously. They arrived as scheduled and where professional and courteous. Cleaned up everything nicely. I have already recommended them to family and friends and will continue recommending them. P.S. Long's also provides a twice yearly maintenance with the first years maintenance free. Thanks Jordan"

Sierra Eco Systems specializes in (GHP) Geothermal Heat Pumps, aka Ground Source Heat Pumps. Our customers save big (average savings $3,000/yr for a 2000sf home) by hiring us to replace their air source heat pump or fossil fuel furnace (propane or oil) with a GHP. GHPs are 400% efficient, extracting 3 parts earth energy for every 1 part of electricity (solar works too). The most efficient electric or fossil fuel furnace are 100%. \n\nGeothermal is the best way to reduce heating & cooling costs according to the US Environment Protection Agency, the US Department of Energy, the CA Consumer Energy Commission, and a dozen other agencies. After decades of study using actual research, not speculation, experts agree that Geothermal heat pumps can heat, cool, and provide domestic hot water more cost-effectively than any other system available today, can last twice as long as conventional systems, offer greater safety (no combustion, no carbon monoxide risk) and greater comfort

"At first it went well. The technicians were professional. They said the install would take 2 1/2 days. The first two days were fine. They asked if they could change the date to finish the install and we said yes. They came for the final 1/2 day of work which turned into a whole day. Early in the afternoon, one technician said he had to leave early. No problem. The other two technicians said they could finish. It went on and on. The two technicians could not figure out how to wire in the thermostat, and they finally gave up. The heat would turn on, but never turn off by itself. My mom had to keep getting up in the middle of the night to turn the unit on and off again to keep from freezing or sweating like in a sauna. They said they would be back the next day to install a simple thermostat and have everything working correctly. .they did not return. Everytime I called the technicians would tell me they were working on roofing jobs for other customers that had to be finished immediately because it was going to rain. After two weeks of this ********, I put my foot down and said I wanted my parent's job finished. Two technicians came out one more time and installed a new, very simple looking thermostat. I thought everything was great and thanked them, only to find out a year later that the new thermostat had also been wired incorrectly and would not come on or shut off on its own. This was the first time my mother has ever had central heat and air. She didn't realize that the thermostat wasn't working properly, and I didn't find this out for an entire year. My mother had a schedule posted on her bedroom wall reminding her when to turn on and off the unit to keep the temperature comfortable. Needless to say, I was ******. I called and asked the company once again to fix the problem. This time they sent out Amoz Marshsll. He was knowledgeable, professional and polite. He fixed the wiring problem in 15 minutes, apologized for it being done incorrectly the first two times and left. He was amazing. I wish he had installed the original unit."
