Heat Pump Service in Mountain View, CA

Heat pumps are the most energy-efficient way to heat and cool homes in Mountain View, CA. With mild winters and warm summers in the South Bay, a properly sized and maintained heat pump delivers comfortable year‑round performance, lower energy bills, and aligns with local electrification and emissions-reduction goals. This page outlines comprehensive heat pump services for Mountain View homes — installations, replacements, repairs, tune-ups, maintenance plans, diagnostics, and system optimization — plus what to expect from technicians, warranties and rebates, and how to prepare for quotes or emergency support.

Common heat pump needs in Mountain View, CA

Mountain View’s climate and housing stock create recurring service needs:

Aging systems struggling to keep up during occasional hot spells or chilly nights.
Inefficient operation due to improper sizing, undersized ducts, or degraded refrigerant charge.
Mini-split and ducted systems needing seasonal tune-ups after long runtimes in summer.
Corrosion or wear from Bay Area humidity and temperature swings affecting coils and electrical components.
Upgrades to high-efficiency inverter-driven systems driven by local incentives and electrification trends.

Our full range of heat pump services

We cover the complete lifecycle of heat pump equipment for Mountain View homes:

Installations: New ducted and ductless (mini-split) heat pump installs, including load calculations and system design.
Replacements: Full-system replacement when repair is no longer cost effective; includes ductwork upgrades as needed.
Repairs: Diagnosis and repair of compressors, reversing valves, fans, controls, and refrigerant leaks.
Tune-ups and seasonal maintenance: Filter changes, coil cleaning, refrigerant verification, electrical tightening, and control calibration.
Maintenance plans: Scheduled inspections, priority service options, and performance checks to preserve efficiency and warranty compliance.
Diagnostics and optimization: Detailed performance testing, airflow balancing, thermostat and control optimization, and energy-saving adjustments.

How the service process typically works

Initial contact and information gathering: Provide basic system details — age, model, observed symptoms, and when issues occur. For quotes, have recent utility bills and square footage available to support accurate sizing.
On-site inspection: A certified technician performs a visual inspection, measures airflow, checks refrigerant pressures and temperatures, verifies electrical connections, and assesses ductwork and insulation.
Load calculation and system design: For installations or replacements, a Manual J load calculation is performed to determine correct capacity and a Manual D duct assessment if ducts are present.
Written estimate and scope of work: Deliverables include a clear parts list, labor scope, timeline, permit requirements, and warranty information.
Permitting and code compliance: For replacements and some installations, local permits and compliance with California energy codes (including Title 24 considerations) are handled as part of the project.
Installation, start-up, and commissioning: Includes leak checks, system charging, airflow balancing, thermostat setup, and a start‑up report showing measured performance.
Post-service documentation: You receive an equipment report, manufacturer warranty registration assistance, and guidance on seasonal maintenance frequency.

What a technician will deliver

Technicians serving Mountain View homes bring industry-standard credentials and clear documentation:

Licensing and certification: California HVAC contractor licensing (C-20), EPA 608 refrigerant certification, and often NATE or manufacturer factory training for specific heat pump brands.
Safety and compliance: Verification of electrical protection, proper condensate handling, and adherence to local building codes.
Written diagnostics: A concise service report that details root cause, recommended repairs or replacement, parts used, and observed system metrics (temperatures, pressures, airflow).
Warranty support: Assistance registering equipment and explaining manufacturer and labor warranty coverage.

Typical diagnostics and fixes explained plainly

Low airflow: Often caused by dirty filters, blocked vents, or failing blower motors. Fixes range from filter replacement to blower motor repair or duct cleaning/repair.
Insufficient heating or cooling: Could be undersized equipment, low refrigerant from leaks, or compressor issues. Diagnostics include pressure and temperature checks; solutions include refrigerant repair, component replacement, or system upsizing.
Short cycling or frequent on/off: Usually a control or thermostat issue, improper sizing, or electrical faults. Technicians adjust control settings, replace faulty controls, or recommend a system with variable-speed technology.
Noisy operation: Loose mounts, failing fans, or compressor problems are common. Resolution includes tightening, replacing mounts, or component replacement.

Warranty and rebate support for Mountain View homeowners

Warranties: Most manufacturers offer limited parts warranties; labor warranties vary. Technicians help register equipment to preserve manufacturer coverage and explain options for extended warranties.
Rebates and incentives: Federal tax credits and California/utility incentives for high-efficiency heat pumps can significantly reduce net cost. Typical documentation required for rebate applications includes equipment make/model, AHRI or efficiency ratings, contractor invoice, and permit approval. Technicians can prepare the paperwork and identify likely local incentives and documentation needs.

Maintenance plans and seasonal care

Regular maintenance keeps heat pumps running efficiently in Mountain View’s mild but variable climate:

Recommended frequency: at least one preventive tune-up per year for moderate-use systems, or twice yearly (spring and fall) for systems used heavily for cooling and heating.
Typical tune-up items: clean coils, inspect electrical connections, verify refrigerant charge, lubricate moving parts, verify thermostat calibration, inspect condensate drains, and check ductwork.
Benefits: improved energy efficiency, fewer emergency repairs, longer equipment life, and maintenance records that support warranty claims and home resale value.

Emergency situations and what homeowners should do

Common emergencies include complete loss of heating/cooling, refrigerant smell, burning odors, or persistent electrical trips. In an emergency:

Turn off the system at the thermostat and the breaker if you smell burning or see smoke.
If you suspect a refrigerant leak or strong chemical odor, ventilate the area and avoid prolonged indoor exposure.
Gather system information before help arrives: unit make/model and serial number, symptoms and when they started, recent service history, and photos if helpful. This speeds up diagnosis and response.

Why timely heat pump service matters in Mountain View

Prompt, expert heat pump service preserves comfort, lowers operating costs, and supports local sustainability goals. A well‑maintained heat pump provides reliable comfort through hot summer spikes and cool winter nights while maximizing efficiency and taking advantage of available incentives. For Mountain View homeowners, investing in professional installation, regular maintenance, and informed repairs is the smart route to long-term comfort and 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.

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.)

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.

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.
