Heat Pump Services in Mountain View, CA

Converting to or maintaining a high-efficiency heat pump is one of the most practical ways Mountain View homeowners reduce energy use, improve year-round comfort, and eliminate dependence on on-site fossil fuels. Heat Pump Services in Mountain View, CA cover consultations for switching from gas to electric heating, system selection and sizing, professional installation of air-source and heat-pipe systems, repair and troubleshooting, ongoing maintenance plans, expected energy savings, available incentives, and post-installation testing and support. This page explains what each service includes, common local issues, and what to expect during the process.

Why switch to a heat pump in Mountain View

Mountain View has mild winters and warm summers, which makes heat pumps especially effective. Modern heat pumps provide efficient space heating during cooler months and cooling in summer with one system. For many homes, that means fewer systems to maintain and a lower carbon footprint without sacrificing comfort. Local electricity rates, decarbonized grid goals, and regional incentives also make conversion from gas to electric an attractive long-term choice.

Common heat pump services and issues in Mountain View

Conversion consultations: Feasibility assessment for replacing gas furnaces or resistive electric heaters with heat pumps, including electrical capacity review and incentive eligibility.
System selection and sizing: Proper sizing to match your home load and comfort goals; avoids undersizing or oversizing which cause short cycling and comfort problems.
Professional installation: Ducted air-source, ductless mini-splits, and heat-pipe solutions installed to industry standards.
Repair and troubleshooting: Diagnosis and repair of common problems like refrigerant leaks, compressor faults, thermostat and control issues, or airflow restrictions.
Maintenance plans: Regular tune-ups to preserve efficiency and prolong equipment life.
Post-installation testing and support: Commissioning, performance verification, and seasonal follow-up.

Consultation and converting from gas to electric

A conversion consultation begins with a site visit or detailed remote assessment to determine:

Existing equipment and ductwork condition.
Heating and cooling load using a Manual J style assessment.
Electrical service capacity and any upgrades needed.
Potential for ductless or ducted heat pump options.
Local permit requirements and incentive opportunities.

Conversion steps typically include electrical panel evaluation, addressing or modifying ductwork, selecting an appropriately sized heat pump (measured in tons and based on heating/cooling load), planning backup or auxiliary heat if needed for rare cold snaps, and completing required permits and inspections. In Mountain View, modest winter temperatures often allow for right-sized heat pumps without extensive backup heating, but each home is different.

System selection and sizing

Correct sizing is key to long-term performance:

Load calculations consider insulation, window area, orientation, and household occupancy.
Efficiency ratings to consider: SEER for cooling performance, HSPF or HSPF2 and COP for heating performance.
Choose a system with appropriate capacity and features for Mountain View climate such as strong low ambient performance and reliable defrost controls.
Evaluate options: ducted central heat pumps, ductless mini-splits for room-by-room control, and heat-pipe or hybrid systems where applicable.

Professional installation and commissioning

Quality installation covers:

Site preparation and placement of outdoor and indoor units for optimal airflow and noise control.
Proper refrigerant handling, evacuation, and correct charge with EPA-compliant practices.
Secure, insulated line sets and proper condensate drainage.
Electrical connections with circuit protection and verification against code.
Ductwork sealing, balancing, and airflow testing where applicable.
Commissioning tests: measured airflow, superheat/subcooling checks, thermostat calibration, and a full system run-through to confirm design performance.

Repair and troubleshooting

Common symptoms and typical checks:

Weak heating or cooling: Check refrigerant charge, airflow, reversing valve function, and compressor operation.
Short cycling or frequent on/off: Verify correct sizing, refrigerant issues, control logic, and thermostat placement.
Noisy operation: Inspect mounting, fan motors, compressor mount, and refrigerant flow noises.
Frequent defrost or frost buildup: Diagnose defrost control, outdoor sensor placement, or refrigerant balance.
Electrical faults: Test capacitors, contactors, breakers, and control boards.

Diagnosis follows a systematic approach: visual inspection, electrical testing, pressure and temperature measurements, and targeted repairs. Repairs are performed with manufacturer parts when available and documented for warranty and future maintenance.

Maintenance plans to preserve performance

Planned maintenance reduces unexpected failures and sustains efficiency:

Biannual tune-ups timed for pre-winter and pre-summer operation.
Filter replacement or cleaning, coil cleaning, and condensate drain inspection.
Lubrication of moving parts, verification of refrigerant charge, and electrical safety checks.
Controls and thermostat calibration, and airflow balancing.
Seasonal performance reports to track efficiency and recommend improvements.

Regular maintenance can extend equipment life and maintain manufacturer warranty conditions.

Expected energy savings and performance

Savings depend on your current system and usage patterns. Typical outcomes for Mountain View homes:

Replacing older gas furnaces or resistive electric heating with a modern heat pump often results in noticeable reductions in heating energy consumption. Many homeowners see significant year-over-year energy use improvement due to the heat pump’s higher efficiency and combined heating/cooling capability.
Because heat pumps also replace separate cooling systems, total HVAC operational efficiency often improves across seasons.
Exact savings vary with home size, insulation, thermostat behavior, and local electricity rates. A sizing and energy-use assessment during consultation clarifies potential savings for your household.

Incentives and rebates in the region

Federal, state, and local programs can offset installation costs and accelerate payback. Mountain View residents should evaluate:

Federal tax incentives and credits available for qualifying heat pump installations.
California state and Bay Area utility rebates and electrification incentives for residential heat pump adoption.
Local municipality or county programs that support home electrification and energy efficiency upgrades.

An initial consultation includes guidance on typical incentive types and documentation commonly required for applications.

Post-installation testing and ongoing support

After installation, thorough testing and support ensure sustained performance:

Commissioning checks to verify airflow, refrigerant charge, and electrical safety.
Documentation of system settings, warranty registration recommendations, and operational training for homeowners.
Options for remote monitoring or seasonal checks to detect performance drift.
Structured maintenance schedules and troubleshooting support for the first year, including post-installation adjustments often needed once the system has settled.

ConclusionFor Mountain View homes, a properly designed and installed heat pump delivers efficient year-round comfort, simplifies HVAC systems, and supports local clean energy goals. From conversion consultations and precise sizing to professional installation, repair, and scheduled maintenance, comprehensive heat pump services ensure reliable performance and help maximize energy savings.

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.

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.)

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.

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.

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.
