Update March 23, 2021 9amThe Service Tech came a little while ago. After calling in to the Tech Office, he learned that re-wiring the house was not necessary. Instead, it was a matter of reconfiguring settings. As he was about to leave I noticed the heat was still running off the furnace - emergency heat mode. So, another ten minutes and now the system is running off the heat pump. Why did I have to point this out?!!Update March 23, 20218amStill having problems with our thermostat and heat pump system. If I had it to do over again, I would not choose the San Carlos office. Disorganized. No one knows what is going on. Lost count of how many times weve had them out. Now, they tell me the wiring has to be re-done! Four hours of work and this after weve had the system a couple of years. One problem after another.Our system, installed by Alternative HVAC Solutions, started putting out cold air instead of heat. The company sent out a technician who was obviously in way over his head. He was here two hours and had to be walked through everything remotely. It was painful. Turns out it was a failed valve which if you ask me, could have been determined fairly quickly. Next, it turns out the installer of the heat pump put it too close to the house inhibiting the technician from being able to reach the part and replace it. So now, someone has to come out and move the heat pump out away from the wall. This was supposed to happen this morning, but here it is late afternoon and there has been zero calls or word from the company about whats going on. Ive called twice and they just tell me they will call me back when they know something. Not even a window of when they might be here. We were charged $320 for the first visit, which seems like a lot for diagnosing a problem over the phone with the guy in the office. Its winter with cold temps. Fortunately we didnt get rid of our furnace and have it as a back up. Frustrated.

Mike and his team did a great replacing our HVAC unit for our office.I would recommend Alternative HVAC Solutions any time!Danny CoxBay Digital, Inc

We got solar panels put in a few years back with the intention of getting electric heat for the house. Mike and his crew (includes the office folks too!) were the ONLY ones that KNEW how to install a heat pump (runs on electricity) that we could find here in the Bay Area. All the others were trying to sell us something else or talk us out of our system.They put the system in. It needed a little time to work out the kinks, but the service guys were on the job with timely service.If you are considering a heat pump option, Mike and the team at Alternative HVAC Solutions are by far the obvious choice. Others may be catching up, but these folks know what they are doing. If you are going with gas heat, they also know what they are doing here as well. We got a gas furnace to work in conjunction with our heat pump on those really cold days.Pricing was also very competitive.You can look elsewhere, but youd just be wasting your time!

Was a very good experience

Girl on the phone was friendly when scheduling an estimate for a water heater replacement. Ramon was scheduled to arrive between 2:00 and 3:00 but did not show up until after 4:00 and no one called beforehand to let us know. Wasted my time. Not getting my business.

From initial contact to post install visit, a thoroughly professional firm. They were not the highest or the lowest among four bids, but the experience working with them has me place them the highest in value.Jeff Meyer, from his first visit to estimate the work, addressing all my questions during the proposal stage, helping slot us into their busy job calendar, then following up afterward, was the best project contact I had worked with.Contracts folks were quick on their follow ups to make sure the project moved along.The onsite crew gave me a time estimate and delivered on it, leaving the premises cleaner than when they arrived.I would be more than happy to recommend this company to anyone who is looking to get HVAC work done. I plan to turn to them for my heat pump water heater in the near future.

Super fast and easy. Came and fixed our broken ac in an hour. Recommended new filter which we ordered on Amazon and replaced ourselves. Very happy!

Our 80 year old gravity gas furnace was not working, after calling several HVAC companies who no longer worked on these units, I was referred Alternative HVAC in Menlo Park. Nat, their service tec, diagnosed, replaced a part, checked everything and was done in an hour, leaving a happy and warm customer.

Alternative HVAC should have a 5 out of 5 stars!!!Seriously, Alternative HVAC saved me over $12K. After our air conditioning unit was not working and all thermostats in our home were toast, I had called Service Champions since they appeared to be the highest rating on yelp and Google. You cant always trust these ratings but please believe you can trust this one...To make a long story short, a technician from Service Champions came out, spent about 5 hours and over $440 dollars later our system was still not fixed. I was told that we needed to have our entire system rewired and the reason the system wasnt working was due to the wires crossing. He said to fix this it would cost over $4K. The tech recommended that we consider purchasing a new unit given the cost. I agreed to speak with someone from their company about a new unit and have them double check our system. Today, they had another technician come out to check our unit and talk to me about purchasing a new unit. He looked at the system and reconfirmed our unit was toast and that I should purchase a new unit and have it reinstalled properly.I told him that I was going to get a second opinion and he assured me that the first technician who I will leave nameless was their best technician and that I shouldnt delay in getting a new unit since he looked at it and gave his recommendation to move forward. He then started to talk about the temperature how hot its going to get this week and to get this done soon, he needed a contract signed today. He was sure I needed a new unit. He quoted me $12,500 for a new unit, installation and a great 10 year warranty on parts and the unit.At this point was disappointed since I thought my only option was to pay thousands of dollars and possible over $12K for a new unit. Not happy at this point.I asked a round a bit and got a recommendation from a friend and he told me to call Mike at Alternative HVAC. I called and spoke to the receptionist here and she had one of their technicians, Nate out at our home within the hour. Apparently there was a cancellation, nonetheless I was pleased.Within 30 minutes he had the unit working, air conditioning humming and at a fraction of the price. He said I did not need a new unit only needed to replace a failed transformer. The total cost was about $225. Much less than what I paid at Service Champions and they fixed our system with integrity.Bottom line: Alternative HVAC save me thousands of dollars! They fixed my unit with very little fuss and clearly had integrity while doing it.I would totally recommend Alternative HVAC! These are now my HVAC guys for life!
