"Needed my duct system under house replaced with better design system that was balanced. Had at least 5 local HVAC Contractors come out to give estimates and Comfort Factor Mechanical estimate was much lower than the "local" companies. Work was completed in 1-1/2 days (two men) which included demo of the old and replacement with new. System works great and would definitely recommend Comfort Factor Mechanical for any HVAC work, repair, or replacement. Eric and Arik are both very knowledgeable about any type of equipment and fully understand a well designed and installed system."

"It went very well; the thorough HVAC system checkup revealed some questionable component that were best suggested to be replace with new ones. I am not confident that my HVAC system is set for more that good performance going forward. I appreciated the non-pressured advice and suggestions in coming to my decisions. Thank you, Joaquin Ortiz."

"Squeezed me in for a super fast response, and speedy diagnosis of A/C failure. The needed replacement capacitor was in the truck and was installed and temperature under control within 20 minutes. The owner also assured me that there s no reason to consider replacing the nearly 20 year old unit for the foreseeable future. Great service, friendly and professional, a decent price, and helpful advice. Money well spent!"

"Computer did the "gotta send info to Microsoft" but when tried to reboot it ran through automatic repair without success. I did all the alternative without any success. He came and picked up the hard drive on Tuesday and returned it on Saturday. Fortunately he was able to "restore" without any data loss. Very happy with outcome."

"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."

"I'm very happy with the work that was done by Landmark construction and energy crew. At first, we met with Ron that came over and met with us about the issues that we had with our water heater and with the bills that we currently pay for electric. Ron recommended us to replace the bulky old water heater and to install a tankless system that will supply hot water immediately and with the use of less gas. We liked that idea and we decided to go for this project. Ron came over to our house with his 2 people that basically took care of all the removal and the installation of the new system. The work that they did took only 2 days from start to finish and now we have more space at the garage, and the bills are much lower than before…."
