Heat Pump Installation in Woodside, CA

Upgrading to a modern heat pump is one of the smartest decisions Woodside homeowners can make for year-round comfort, lower energy bills, and reduced carbon footprint. Whether you live in a rustic hillside estate or a compact town property near the Peninsula, professional heat pump installation in Woodside, CA focuses on site-specific design, careful sizing, and code-compliant installation so your system performs reliably through cool coastal nights and occasional inland heat.

Why choose a heat pump for Woodside homes

Woodside's Mediterranean climate means mild, wet winters and dry, temperate summers. That creates a strong case for heat pumps that both heat efficiently in cooler months and provide consistent cooling during warmer days. Many Woodside homes have high ceilings, vaulted spaces, or open floor plans—features that require thoughtful zoning and airflow planning to avoid uneven temperatures. Heat pumps also integrate well with electrification goals and local energy programs in the Bay Area, offering long-term savings and reduced dependence on fossil fuels.

Common heat pump installation issues in Woodside

Undersized units that struggle to keep large, open rooms comfortable.
Improper refrigerant line length for hillside properties with long runs between indoor and outdoor units.
Inadequate electrical service or panel capacity for larger heat pump systems.
Poor zoning choices that create hot and cold spots in multi-level homes.
Difficulty routing ductwork in older homes with limited attic or crawlspace access.

Addressing these issues starts with a thorough site survey and accurate load calculations.

Site survey and evaluation

A professional site survey for heat pump installation in Woodside, CA includes:

Inspecting the building envelope: insulation levels, window orientation, air leaks, and roofline.
Assessing room layouts, ceiling heights, and likely zones for temperature control.
Reviewing existing HVAC equipment, ductwork condition, and electrical panel capacity.
Measuring outdoor space for equipment placement, clearance requirements, and noise considerations relative to neighbors and property features.
Noting obstacles common in Woodside: steep driveways, long runs for refrigerant lines, and protected vegetation that can affect equipment siting.

This on-site information drives system selection and installation planning.

Choosing between ducted and ductless systems

Ducted heat pumps: Best where existing ductwork is in good condition or for whole-house installations to preserve aesthetics. They deliver balanced airflow and are often preferred for larger, single-system installations in homes with accessible attics or basements.
Ductless mini-splits: Ideal for additions, room-by-room upgrades, or homes with poor or no ductwork. They allow targeted zoning, higher efficiency for small spaces, and easier installation when structural constraints exist.
Hybrid approach: Many Woodside homes benefit from a combination of both—using ducted systems for central living areas and ductless heads for remote rooms or wings of the house.

Selection depends on performance goals, architectural constraints, and budget priorities.

Load calculations and proper sizing

Accurate sizing is essential. Professionals use Manual J style load calculations to evaluate heating and cooling needs based on:

Square footage, orientation, insulation, window types, and occupancy.
Local Woodside climate data and elevation effects on performance.
Desired indoor temperatures and humidity control preferences.

Oversized systems cycle often and reduce efficiency, while undersized units fail to maintain comfort. Proper sizing ensures consistent performance and longer equipment life.

Professional installation steps

A typical installation workflow covers:

Permit review and scheduling with the San Mateo County building department when required.
Site preparation: protecting flooring, staging equipment, and confirming access paths for outdoor units.
Removal of old equipment (when applicable) with safe refrigerant recovery and disposal.
Mounting indoor and outdoor units, running refrigerant lines, condensate drains, and electrical wiring.
Electrical work: verifying circuit capacity, installing dedicated breakers, and connecting to the main panel per local code.
Refrigerant work: brazing, evacuating lines with a vacuum pump, pressure testing, and charging to specified levels.
Ductwork modifications or fabrications when ducted systems are used.
Commissioning and performance testing (detailed below).All refrigerant and electrical steps are performed by licensed technicians following safety and code requirements.

Commissioning and performance testing

Commissioning confirms the system works as designed:

Vacuum and leak tests for refrigerant lines to ensure system integrity.
Accurate refrigerant charge and superheat/subcooling measurements to manufacturer specifications.
Airflow checks, duct leakage testing when applicable, and static pressure measurements.
Thermostat calibration and zoning controls setup.
Operational run tests to verify heating and cooling capacity, defrost cycles, and noise levels.Commissioning documentation typically accompanies the installation so homeowners have a record of initial performance.

Warranty, permits, and compliance

Expect clear information about factory equipment warranties, labor workmanship warranties, and permit signoffs required by San Mateo County. Proper paperwork ensures warranty eligibility and that installations meet local building and electrical codes. Staying compliant also protects property value and simplifies future inspections or resale.

What customers can expect on install day

Professional arrival with tools and protective coverings to keep your home clean.
A focused timeline that may range from a half day for a simple ductless swap to several days for full-system ducted installations.
Minimal disruption: technicians coordinate access, manage debris, and secure outdoor equipment placement on stable pads or mounts.
A final walk-through explaining system operation, thermostat use, routine maintenance needs, and warranty documentation.

Technicians should leave the site tidy and provide a plain-language summary of system features and maintenance intervals.

Maintenance recommendations and long-term performance

Routine maintenance keeps heat pumps efficient and reliable:

Change or clean filters every 1 to 3 months depending on use and indoor air quality.
Annual professional tune-ups to inspect refrigerant levels, electrical connections, and airflow.
Keep outdoor units clear of vegetation, debris, and snow in winter months.
Monitor for unusual sounds, increased energy use, or uneven heating and address issues early to avoid major repairs.

In Woodside, seasonal checks before winter and after heavy pollen or wind events are especially valuable.

Benefits summary

Efficient year-round heating and cooling suited to Woodside's climate.
Improved indoor comfort with zoning and humidity control options.
Lower operating costs and alignment with regional electrification goals.
Quiet, low-maintenance operation when installed and commissioned properly.

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.

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.
