Heat Pump Water Heaters Services in Mountain View, CA

Heat pump water heaters are essential appliances in modern homes, providing reliable hot water for everyday needs such as bathing, cooking, laundry, and cleaning. Unlike traditional water heaters that generate heat directly, heat pump water heaters use electricity to move heat from the surrounding air into stored water, making them significantly more energy efficient. These systems are electric by design and are typically tank-style units, with variations that include integrated (all-in-one) models and hybrid systems with electric backup elements.

Heat Pump Water Heater Services in Mountain View, CA

Heat pump water heater services in Mountain View, CA provide an energy-efficient way to produce reliable hot water while reducing operating costs and supporting California’s electrification goals. By transferring heat from the surrounding air into stored water, these systems use significantly less electricity than conventional electric resistance water heaters. Plum HVAC works with homeowners and small commercial properties throughout Mountain View to install, maintain, and repair heat pump water heaters designed for long-term performance in the Bay Area’s mild climate.

This page outlines heat pump water heater system options, proper sizing, professional installation and permitting, maintenance and repair services, energy-savings expectations, rebates and incentives, warranty considerations, and installation factors specific to Mountain View homes.

Why Choose a Heat Pump Water Heater for Mountain View Homes

Heat pump water heaters are specifically designed to heat domestic hot water efficiently rather than condition indoor air. Because Mountain View experiences relatively stable, moderate temperatures year-round, these systems typically operate at higher efficiency levels compared to colder regions.

Key benefits include:

Lower monthly electricity costs compared to standard electric water heaters
Reduced greenhouse gas emissions
Compatibility with all-electric home upgrades
Strong performance in Bay Area coastal and inland climates

Plum HVAC evaluates household hot water usage, available installation space, electrical capacity, and long-term efficiency goals to recommend systems that deliver consistent hot water and measurable energy savings.

Types of Heat Pump Water Heater Systems

Integrated (All-in-One) Heat Pump Water Heaters

These systems combine the heat pump and storage tank into a single unit. They are commonly installed in garages, utility rooms, or mechanical spaces with adequate airflow.

Split System Heat Pump Water Heaters

Split systems separate the heat pump from the storage tank, offering more flexibility when indoor space, noise sensitivity, or placement constraints are a concern.

Hybrid Heat Pump Water Heaters with Electric Backup

Hybrid models primarily operate in heat pump mode but include electric resistance elements to support high-demand periods or temporary efficiency limitations.

Heat Pump Water Heaters Paired with Solar PV

When integrated with solar photovoltaic systems, heat pump water heaters can be scheduled to run during peak solar production, further reducing grid electricity usage.

Plum HVAC helps Mountain View homeowners compare efficiency ratings, space requirements, upfront costs, and long-term operating expenses when selecting a system.

Heat Pump Water Heater Sizing & System Selection

Proper sizing is essential for comfort, efficiency, and system lifespan. Undersized systems can struggle to meet demand, while oversized systems may increase upfront costs without added benefit.

Sizing considerations include:

Number of occupants

We found Plum HVAC in 2024 after spending more than 2 months searching and comparing estimates. The owner Sam gave us a very competitive price for a Mitsubishi mini-split and the installation went off without a hitch. Our experience was so positive that we later requested their services twice more to also install A/Cs for our 2 other rooms. Their technician, Jake, led our installations each time and we were very impressed by their professionalism and quality of work. Now 1 year in and we could not be any happier, nor have we encountered any issues with our models.

Sam of Plum HVAC, responded to our Heat Pump installation request promptly and provided a very competitive estimate after an onsite visit. He was very flexible and patient to answer and explain our questions. After we signed the contract, he and his team of 4 worked very hard to deliver and install the whole Heat Pump system on time with good quality. I am particularly impressed by their problem solving skills to overcome different connection challenges for the attic installation. Each day before they started, they covered the floors with protection blankets and cleaned after they were done for the day. They also revised the drainage and electric work per the city inspection guidance. Sam and his team were professional and honest so we highly recommend Plum HVAC to any customers who need HVAC work done for their houses.

We needed to install a mini-split in a backyard unit. Sam and his team helped with this, and they did a fantastic job. Sam visited our place and clearly explained to me what needed to be done, and offered a great price. He scheduled the job for a few days later, and his team performed the job with extraordinary quality. Later, I noticed a minor issue and reached out to them. Sam helped me to fix the issue on a second visit by his team later in the week, providing top-notch customer service. I will work with them in the future for my HVAC jobs, and highly recommend them given their excellent work quality and customer service.

I reached out to 4 companies for mini split quotes; Plum HVAC pricing came in the lowest. Beyond that, Sam was very knowledgeable and kind during the in home consultation. He offered a quote in person, & stuck by it. They removed our old furnace, and installed a two head mini split in our two story townhouse. The work as you can see is very clean! The guys who installed it were very fun & professional. Sam & his team were communicative the whole way through including the permitting process. They took roughly one full day for install, which was very fast! Including removal & disposal of our old furnace. Natalie was very helpful throughout the Bayren Rebate process & always available for any questions! This system has changed our lives, wish we would have gotten it done sooner! It’s way better than we could have imagined.

I recently engaged Plum HVAC to install two mini-split units at my residence, and I'm thrilled with the outcome.Throughout the entire process, from the initial consultation to the project's completion, Plum HVAC showcased professionalism and expertise. The technician, Sam, arrived promptly and conducted a comprehensive assessment of my HVAC system. Sam took the time to thoroughly explain the technicians' tasks, the estimated duration of the project, and provided transparent pricing options.

Wonderful experience with Plum HVAC on a heat pump installation! I checked several companies, compared their recommendations, timelines, reputations and prices.Sam, the owner, was very professional and has almost 2 decades of experience in HVAC. When I asked dumb questions, he answered most graciously. And when I noted that some companies we queried said we could get away WITHOUT replacing our original ductwork from 1965, he gave us his honest opinion why that wasn't a good idea. (Hubby remembered later that people who worked in our attic adding insulation told us there were lots of duct leaks.)

Marlene S.

5.0

I called 8 different HVAC companies for quotes for a heat pump heating/ac system because I want to save money by switching from a forced air gas furnace to an electric heat pump system which will give me both heating and air conditioning. In addition my old furnace (circa 1991) was way oversized for my home and the air coming out too noisy. The New heat pump system is quieter and more efficient. Back to the quotes for the system, all the other 7 companies sent a salesperson/advisor to give the quote. Sam, the owner of Plum HVAC came our to give the quote. He was quick with his quote and was very knowledgeable. He didn't try to upsell me on anything and have the lowest quote of them all. His price was 60% less than the highest quote and 15% lower than the next second lowest quote.

Plum HVAC is an extremely professional, knowledgeable, and an established company to hire. I highly recommend Plum HVAC! Sam and his crew did a wonderful job. Sam worked with my schedule and his crew had completed the job with ease.

Sam was one of the most professional business owners I had the chance to meet over the past few years and I'm so happy I trusted him to install our new A/C unit.- He showed up on time- He was transparent (and reasonable) regarding pricing- He offered 2-3 options- His crew did a very clean/thorough jobWhat I loved the most though, was the fact he was very easy to communicate with. I would definitely use him again and recommend him to our neighbors/friends.

We recently had a complicated Bryant Evolution dual fuel system with variable speed and zoning installed in our home by Plum HVAC, and we are very pleased! The team also changed the entire crawl space ducting, ensuring a comprehensive upgrade. The price was fair, and the team was always on time and easy to contact. Sam Mousavi, the head of the team, paid great attention to detail and demonstrated a strong understanding of systems. His expertise in HVAC systems and his friendly character made us feel comfortable throughout the process. We highly recommend Plum HVAC for their professionalism and excellent service.

Amirali B.

5.0

I cannot say enough about Plum HVAC, who replaced my aging heater furnace, and in particular Sam. Sam was very highly recommended by my sister, who replaced her furnace and added air conditioning.First, they gave me a good deal for a 2-stage, at the same cost as the lowest bid for a 1-stage. The other bids were dancing around some gas line work made by previous owners.
