I will never use fountain valley mechanical again. I used them to install a new boiler less than a…read moreyear ago. At the time they installed it, they removed the backflow preventer that was connected to the boiler and forgot to reinstall it. This had been installed on the previous boiler and was required by law. It was laying on the floor. I called them back, told them they needed to reattach this as it is required by law and they came back and put it back on. Now approximately six months later, I had a RP backflow inspection that is required annually. The backflow inspection failed and it leaked in the brand new boiler Fountain Valley had just installed. The inspector noticed Fountain valley made a mistake putting two backflow preventers on the boiler now, instead of just the single testable backflow device that should be attached to the boiler. There are now two devices, one that is testable (the one I had them reattach) and one they installed that does not need to be there and is not testable. If someone at fountain valley knew what they were doing they would not have installed the non testable device as it was redundant. I didn't need it and yet I was charged for it. In addition, they turned both valves to the backflow device off causing water pressure issues. I called fountain valley and told them the backflow preventer is leaking and my inspection failed. Matt, the owner came out and proceeded to start yelling at both my plumber and me. He swore at us and used extremely vulgar language claiming they did nothing wrong. They obviously didn't know what they were doing. They installed a duplicate backflow device that isn't testable, messed up my testable backflow device and turned off both valves to the device. I had to pay the inspector/plumber on site to fix all of their mistakes on a brand new boiler. Ridiculous. I will never use them again.

I have used FVM for decades. They have come out in emergencies in a snowstorm and a Polar Vortex…read more Our furnace, hot water heater, and AC have all been installed by FVM. They came out in Jan 2023 when the cold ruptured our kitchen water lines in numerous places. Not only did the repairs in brutal cold working on his back to access the outside crawl space but he installed two shut off valves so if this happens again we will not have to shut all the water off to the whole house. The price of regular inspections has remained steady for years. Techs have always been friendly, professional and informative. Highly recommend this company.

This business went under, and (kind of) sold out to One Source Home Service. They promised me…read moremultiple years of service calls when I spent thousands with them on a furnace, and continually assured me I'd be taken care of. They left me with a bad furnace with a motor that didn't run and One Source wouldn't fix it for free - so One Source is not honoring any of the services sold by Mountain View. I was swindled by this company, even though they seemed great at first. Luckily they've closed up shop here but wanted to make sure this was known in case they re-open, and also for customers to know that One Source Home Service isn't really taking care of the commitments for this company that they purchased, which is really a shame.

In January 2025, my furnace died on a Friday during a cold snap. It cost me a bit more to have…read moretechnicians come out on a Saturday, but it was an emergency, so no problem. The technicians were great; no complaints there. I decided to add a heat pump before the tax credits were eliminated. Again, the installers were great. My issue with the company is this. It is now December, and even after multiple phone calls, my new furnace and heat pump STILL have not been inspected by the City of Englewood. The management couldn't be bothered to follow up with a customer who spent $20,000 on a new furnace and heat pump. I even called and asked to talk to the owner. I was told they were in a meeting and would call me back. They never did. I had a City inspector at my house this week to inspect a different project and told him about my experience with Summit Heating and Cooling. He looked up my furnace project and saw they had pulled an electrical permit but not a mechanical permit, so that's why they were not following through arranging an inspection. The City inspector sent them a notice of some sort that they need to fix this, and as of yet, has not received a reply or a fix. All this shows me is this company can't be trusted to do the right thing.
