Heat Pump Installation in San Bruno, CA

Upgrading to a heat pump delivers year-round comfort and energy savings for San Bruno homes. With the area’s mild, coastal climate and occasional fog, a properly chosen and installed heat pump provides efficient heating in winter and cooling in summer while reducing reliance on aging gas furnaces or inefficient window units. This page walks through the full heat pump installation process in San Bruno, CA, so you know what to expect from the initial consultation through warranty registration and how to maximize local incentives and long-term performance.

Why choose a heat pump for San Bruno homes

Efficient heating and cooling suited to San Bruno’s moderate temperatures and coastal humidity.
Lower operating costs compared with older electric resistance heating or inefficient HVAC systems.
Better indoor air quality and quieter operation, important for homes near busy streets or dense neighborhoods.
Eligibility for state and local rebates and incentives that prioritize electric heat pump adoption.

Common heat pump installation issues in San Bruno

Undersized equipment that struggles during cooler spells or on foggy mornings.
Poor outdoor unit placement leading to salt air corrosion or excessive noise.
Inadequate refrigerant charge or improper electrical hookup causing low efficiency and premature failures.
Lack of proper ductwork or incorrect mini-split placement resulting in uneven heating and cooling.
Missing local permits or failure to meet Title 24 or municipal requirements for energy upgrades.

Initial consultation and site evaluation

The install process begins with a detailed consultation and on-site evaluation. Key components of this phase:

Review of your home’s layout, insulation, window orientation, and existing heating/cooling equipment.
Assessment of electrical capacity and panel location to determine any upgrades needed for the new system.
Roofline, yard, and outdoor space review to find a durable, code-compliant outdoor unit location with proper airflow and maintenance access.
Discussion of lifestyle needs: preferred indoor temperature ranges, rooms of priority, and noise sensitivity for outdoor or indoor units.
Identification of any permit requirements or HOA guidelines specific to San Bruno neighborhoods.

This step ensures the selected system matches both performance needs and local constraints like limited yard space or elevated salt exposure near the bay.

Equipment selection and sizing

Choosing the right heat pump is critical. Factors taken into account:

System type: ducted central heat pump, ductless mini-split, or hybrid systems that pair with existing gas furnaces.
Capacity sizing using Manual J load calculations tailored to San Bruno’s climate and your home’s envelope to avoid oversizing or undersizing.
Efficiency ratings: SEER for cooling, HSPF or COP for heating performance—higher numbers mean better efficiency and potential rebate eligibility.
Corrosion-resistant components and protective coatings for outdoor units to withstand coastal conditions.
Noise ratings and inverter-driven compressor technology for quieter, more responsive operation in compact neighborhoods.

Proper sizing and equipment selection prevent common issues like short cycling, uneven comfort, and excessive energy use.

Professional installation steps

A quality installation follows a clear sequence to ensure safety, performance, and longevity.

Pre-install prep

Pull required permits and schedule inspections per San Bruno and San Mateo County codes.
Protect work areas indoors and outdoors; plan for condensation and refrigerant handling.

Indoor unit placement

For ducted systems: inspect and modify existing ductwork, seal leaks, and install proper return and supply grilles.
For ductless systems: place wall or floor-mounted heads to achieve balanced airflow and optimal comfort, avoiding direct drafts on seating areas or beds.

Outdoor unit placement

Mount on a concrete pad or anti-vibration bracket above flood and debris levels, with clearance for airflow and maintenance.
Position to minimize exposure to prevailing winds carrying salt spray and to reduce noise impact on neighboring properties.

Refrigerant lines and charging

Run copper refrigerant lines with proper insulation and slope for drainage.
Evacuate the system to remove moisture and non-condensables and charge to manufacturer specifications using electronic gauges.
Accurate refrigerant charge is essential for efficiency and compressor life.

Electrical hookups

Install dedicated breakers and disconnects sized to manufacturer requirements.
Proper grounding and surge protection to protect electronics from coastal lightning or grid surges.
Integrate thermostat or controls, including smart thermostats or zoning controls where applicable.

Safety and code checks

Verify all wiring, refrigerant, and mechanical work meets local codes and manufacturer installation instructions.

Commissioning and performance testing

After physical installation, thorough commissioning confirms the system operates as intended:

Leak tests and pressure checks on refrigerant lines.
Performance testing under both heating and cooling modes to verify capacity and efficiency.
Airflow measurements across supply and return registers to ensure balanced distribution.
Electrical load and amperage checks for compressor and fan motors.
Verification of defrost cycles and control logic for consistent winter performance in foggy, humid conditions.

Documented test results help with warranty registration and future troubleshooting.

Post-installation walk-through and warranty registration

A comprehensive walk-through ensures homeowners understand system operation and maintenance:

Demonstration of thermostat controls, mode settings, and scheduling for efficient use in San Bruno’s climate.
Explanation of filter types, cleaning intervals, and simple seasonal checks to sustain performance.
Provide manufacturer warranty information and guidance on registering warranties and service contracts to protect investment.
Delivery of final paperwork, permit sign-offs, and testing reports for your records.

Tips to maximize efficiency and local rebates

Optimize setpoints: Slightly adjusted temperature schedules reduce runtime without sacrificing comfort in mild coastal weather.
Improve envelope performance: Add insulation, weatherstrip windows, and seal ducts to reduce load requirements and boost efficiency.
Consider smart zoning: Target heating and cooling to occupied areas to lower energy use and wear on the system.
Maintain regular service: Annual tune-ups, coil cleaning, and filter changes extend equipment life and preserve warranty coverage.
Explore incentives: California and regional programs often offer rebates for high-efficiency heat pumps and electrification projects. Check eligibility for equipment efficiency levels and installer certification requirements to ensure rebate qualification.

Final considerations

A proper heat pump installation in San Bruno, CA blends the right equipment choice, precise sizing, and meticulous installation to deliver reliable comfort and lower operating costs. Paying attention to coastal environment factors, local codes, and thorough commissioning preserves performance and warranty protection. With correct planning and maintenance, a heat pump is a long-term investment that improves comfort, reduces emissions, and aligns with regional energy goals.

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.
