    New electric heat pump (aka hybrid) water heater
    Angela L.

    Made an appointment with Matt for estimates on replacing our gas water heater with an electric heat pump water heater, and also wanted to get a quote on replacing our a/c and gas furnace with a heat pump and air handler. Matt showed up on time, and spent a long time patiently discussing both installs. Absolutely zero sales pressure. 4 days later, we received the detailed quotes via email. As these were our first estimates, we had nothing to compare them to. We had another estimate lined up, but before we could get the written quote, our water heater started flooding our basement (how's that for timing?!). We called, and Matt spent a lot of time to get the water heater and crew asap. The installers were able to come just 4 days later, remove our old water heater, install the new one, and do all the associated work (there's quite a lot). The 3-person team (Michael & his crew) did a stellar job, being able to avoid adding a pump to deal with the condensate line by adding a stop valve, and avoided running electrical conduit all over our garage by going through the attic. Everyone was extremely pleasant and polite, and they cleaned up any mess they may have made. We haven't made up our minds yet about the HVAC, but if we decide to do it, I will of course update this review. In the meantime, I highly recommend this company.

    I discovered Sierra Valley Mechanical through SMUD's heat-pump rebate program in which I reached out to three different companies. I completed the website form on a Sunday night and didn't expect to hear from anyone until Monday morning. To my surprise, I received an email from the owner, Mike, in about five minutes! We went back and forth in email and even though I told him I had two other companies I need to vet he was quick to place me on his schedule knowing that I needed the service completed quickly. Call it confidence to win a bid but it's also excellent customer service. Operations Manager, Matt,, was out the next day to assess the need and I had a quote the end of the day. Needless to say, I think it's obvious by me writing this review that Sierra Valley Mechanical won the bid. While they weren't the cheapest or the most expensive, they had the best proposal and Matt highlighted needs the other two contractors neglected. That gave me assured that Sierra Valley Mechanical was the right company to do the job. The process to accept the contract and receive the county, state, and federal rebates was effortless thanks to Suzy. She called when it was needed and emailed when it wasn't. In no time, all the rebates were taken care of and the contract signed. The crew arrived on-time and introduced themselves. Francisco, Kris, and Eric were friendly and made an effort to work without disrupting our daily household activities. It only took them about a day and a half to complete the project and when it was done, we had sweet cool air. There was no mess left behind the work was done top notch. Francisco wouldn't leave until he was absolutely sure I was happy with everything. Since he left, you know I was. :) Sierra Valley Mechanical did such a great job on my system that I had them back two weeks later to replace the second smaller living quarters HVAC which was running fine. I wanted to take advantage of the rebates and quite frankly, loved the performance of the Bosch on the other side of the house that I just had to have my entire house running Bosch. Even though this job was tougher than the first, the same crew did a great job and was done within two days again. They rocked. Hands down, if you need a new HVAC system, give Sierra Valley Mechanical a call and tell them you want Francisco, Kris, and Eric working on the job. You won't be disappointed.

    New heat pumps

    I've been in the energy business for a long time and appreciate working with Sierra Valley Mechanical on our church's energy upgrades. They are knowledgeable and reliable, and their crew was very professional. I enjoyed working with them. They installed heat pumps, LED lighting, thermostats, and a heat pump water heater. I also appreciated their punctuality, how they cleaned up after their work, and that they kept me well informed. There were no surprises; it was just quality work on schedule. Their office staff is equally efficient and great to work with.

They sent Thomas out to take a look, he was very up front about the condition of the unit and advised that there was alot of issues, which we totally get. He was very thorough and took a lot of reference photos and explained what he was doing. We agreed to look at getting a new system and set up a meeting with Kyle for later the afternoon. Kyle was also amazing and went over the pricing and options, you never want to pay for a new AC unit but it's a necessity here so and they made sure we had a great deal. Installation will be later this week! I look forward to a frosty summer!

I met with the owner Mathew McGuire, who I found to be friendly, sincere, and someone who is vested in his business, his people, and working to ensure that he wins life-long customers with every job. I had done a lot of research with AI, so I knew my options well (that research was very helpful and I'd highly recommend doing it in advance of having people out to give you pricing). I had no intention of beating up each of the companies, I simply asked for their best pricing and options. I used AI to carefully review each bid in detail, including the proposed equipment and how appropriate it was for our home. All companies gave solid bids, but there was a very large spread between the highest and lowest. That usually concerns me, but all my research about American Energy indicated that they were a solid, competitive company. It was a big investment, but I ended up converting to an electric heat pump and also getting all our ducting replaced. We have a 2750 sf single-story home with 17 vents, so the new ducting was nearly as much as the system itself. That said, the ducting has made so much difference in terms of balancing the temperature throughout the house, which was a real probelm with the old system. The new system is extremely quiet and maintains a consistent temp throughout the day--and we've had some extremely hot days since it's been installed. American Energy's installers were all very friendly and professional, and did a great jobs with prep and clean-up each day they were here (the initial install took two days). There were a couple minor issues after the install was complete which required two follow-up appointments. One was a equipment issue that required Carrier to provide a replacement part, but Carrier was responsive and quickly provided it. For the additional follow-up appointments, their scheduling person as professional, courteous, and accommodating. In fact, she went out of her way over a weekend to re-schedule an appointment that was supposed to happen on a Monday morning. To me the company has to be a good one to A.) get that kind of diligence out of employees, and B.) to keep those kind of employees. In the end, I'm extremely happy with the system and will gladly subscribe for their annual maintenance contract.

The service technician Christian arrived on time and courteously introduced himself and his service procedure. He used a handheld meter to measure pressures and other important data about the unit's performance. He showed me the results on his meter: a loss of pressure, probably because of a coolant leak. He laid out my options and answered my questions. After getting my approval, he replaced the missing coolant and added a dye kit that would help find the leak. He also mentioned the dye kit included a sealant that might close up any small leaks. After adding the coolant and dye kit, the HVAC unit quickly brought interior temperatures down. Short-term problem solved. Christian explained that AirMech offers a maintenance plan that I should consider. It pays for regular inspections and provides a 15% discount on the work he had just completed. I opted in. The money I saved that day will more than pay for a whole year of the maintenance plan. A couple weeks later, I called AirMech again to have them inspect the lines to look for leaks. Christian was my man again. He arrived bright and early and performed a visual check in the attic. Then he hooked up his meter to the outdoor HVAC unit. He showed me the results and interpreted them for me: all readings are in the "ideal" range. It looks like the dye kit with sealer did its job. And because I had opted into the maintenance plan, there was no charge for the visit. Long-term problem solved. AirMech's staff operated with professionalism and integrity. I will call on them for my future HVAC needs. And I hope I get Christian again!

Every company kept telling me my freon was low and i most likely had a leak.
