Best heating and air conditioning pros near San Mateo, CA

"Our HVAC unit wasn't working and was recently repaired by another shop.  After a couple of weeks, it stopped working again.  The other repair shop couldn't figure out what was wrong...after replacing the board and fuses.  They claimed the unit was old and we needed an electrician to fix the electrical problem.
The appointment with Duke started off poorly...he forgot about the appointment.  After calling to ask where he was, he made it over in 45 mins.  We wanted Duke to give us an estimate to replace the Heater and A/C unit.  He took measurements and drafted up an estimate to replace the HVAC, roughly $4500.  Then he asked what was wrong with the unit.  Out of curiosity, he looked at the wiring and replaced the fuse.  After, the fuse blew out a number of time, he was able to figure out a wire had melted and was causing it to blow the fuse.
So after spending $300 with another company to replace the board and having the unit still not work, Duke was able to fix it for $150 (service call).  Then told us the unit should be good for another 5-10yrs.  He may have lost out on a $4500 job replacing the unit and getting only $150 for a service call, but he's going to be our first call the next time we ever have a repair job and eventually replace the unit.  It's great to find honest, competent repair guys like Duke!!  Thanks!

"I first contacted Valley to get a quote on how much it would cost to get air conditioning installed. I live in an older town home that is approximately 1100 sq. ft. They sent someone out to take a look and see what was involved. He was very professional and explained what was involved including getting permits from the city. He quoted the amount and provided me with an invoice. I contacted them 3 months later to say I was ready for the install. The installation turned out to be quite challenging due to the way my home is constructed, but Valley made it work. The service person had to stay a few hours longer but I wasn't charged anything extra for it. They stuck with the amount of the estimate that was quoted. It's only been a couple of months since the install, but I have to say my only complaint at this point is how cold it gets when I turn on the air. But that's a nice problem to have. :)"

"Great Job! They made it quick and easy to have HEAT back in my home! Thank you Rudy!!"

"Alanis Air did a great job with my HVAC project. John Alanis answered all my questions and worked with me in deciding which system I should choose when replacing my very old system. His crew completed the work in one day, cleaned up the area and disposed of my old system. They were very efficient, knowledgeable and friendly. I would recommend Alanis Air for any of your HVAC needs! Thank you John, Santiago, Angel and Ismael :-)"

"I highly recommend Aire Serv of Campbell & Saratoga to anyone in need of HVAC services. Alton helped me find the right system that works for our home within my budget. Alton was knowledgeable and truly explained the different options & HVAC available that would fit for our home. Alton answered all my questions with patience and expertise. The installation crew (Rene & Julio) were on time and explained the complete removal our old system and installation of the new HVAC. They treated my home with respect, cleaned up thoroughly after the job. I like their attention to detail and commitment to doing the job right the first time. Thank you for making our home energy efficient. I'm happy with the results."

"Michael, the estimator, came out and got all the information. He was very professional and even talked about various different options including putting the heater in the attic. He was very knowledgeable. I chose to go with another company, but I believe that Albert Nahman Plumbing and Heating would have done a great job on the work proposed."

"Javier is an honest, reliable, and professional. Quickly assessed the problem; provided me all the options and reasons behind each. He was on time and even more importantly will let you know when or if he believes he is running late. Very responsive as well. Also, his prices or fees are reasonable. Generally as easy guy to work with. Will definitely use for any future HVAC needs and confident in referring him to a close friend."
