Heat Pump Installation in Daly City, CA

Heat pump installation in Daly City, CA is a smart choice for homeowners seeking reliable year round comfort, lower energy use, and alignment with California electrification goals. Daly City’s mild, often foggy coastal climate means systems need to perform efficiently in cool, damp conditions and provide dependable heating on chilly mornings. This page explains the installation process from site assessment to post install testing, the types of systems commonly used here, what to expect on install day, and important warranty and rebate considerations.

Why install a heat pump in Daly City

Consistent comfort with efficient heating and cooling in a temperate coastal climate.
Better energy efficiency compared with electric resistance heating or older gas furnaces when sized and installed correctly.
Improved indoor air distribution and potential for zoning to balance cool, foggy nights and sun-warmed afternoons.
Eligibility for state and local electrification incentives and rebates that help offset upfront costs.

Common heat pump issues in Daly City homes

Undersized systems that struggle on cool, damp mornings.
Poor duct distribution in older homes leading to uneven temperatures.
Corrosion or outdoor unit exposure to salty marine air in properties near the coast.
Thermostat or zoning systems that are not optimized for multi-level or partitioned layouts.

Understanding these common pain points helps ensure the system you choose is designed for local conditions.

Types of heat pump systems and which suit Daly City homes

Split systems: Standard for homes with existing ductwork. Good for whole house heating and cooling.
Ductless mini split: Ideal for older homes without ducts or for room additions where extending ductwork is impractical. Offers targeted zone control.
Packaged systems: Compact option for properties with limited space for separate indoor equipment. Typically used in specific retrofit scenarios.

Selection depends on your home layout, ductwork condition, insulation, and comfort goals.

Site assessment, system selection, and sizing

A professional installation begins with a thorough site assessment:

Inspect existing ductwork, insulation, attic and crawlspace access, and potential outdoor unit locations.
Measure home square footage, orientation, window types, and envelope tightness to perform a Manual J load calculation. Proper sizing prevents short cycling and ensures efficiency.
Evaluate electrical service capacity and panel space to confirm compatibility with the selected heat pump.
Discuss noise, aesthetics, and clearance for outdoor unit placement, especially important in Daly City neighborhoods with close property lines and marine air exposure.

Correct sizing and placement are critical. Oversized units create comfort issues and increased wear. Undersized units will not meet heating needs on cooler days.

Professional installation steps

A typical Heat Pump Installation in Daly City, CA follows these professional steps:

Pre-install preparation: Confirm permits, utilities, and any local ordinance requirements. Verify equipment model, refrigerant type, and accessory needs.
Mounting and mechanical work:

Install indoor and outdoor units or mount duct connections and condensate lines.
Secure outdoor unit on level pads or wall brackets placed for drainage and corrosion protection.

Refrigerant lines and vacuuming:

Run refrigerant lines with proper insulation and routing.
Evacuate the lines to remove moisture and non condensible gases before charging.

Refrigerant charging:

Charge the system per manufacturer specifications using weight and superheat/subcooling methods to ensure correct refrigerant levels.

Electrical hookup:

Install disconnects, connect to the service panel, and ground the system.
Ensure proper breakers, conduit, and wire gauge for safety and code compliance.

Controls and thermostat wiring:

Wire smart thermostats, zone dampers, and any communication links between indoor and outdoor units.

System startup and adjustments:

Start system, monitor amp draw, pressures, and temperature splits.
Adjust airflow and refrigerant charge as needed.

Each step emphasizes code compliance and manufacturer guidance to protect performance and warranty.

Thermostat, zoning integration, and smart controls

Zoning: Add motorized dampers and separate thermostats to create zones for bedrooms, living areas, and additions. Zoning increases comfort and efficiency in multi level Daly City homes.
Thermostats: Modern heat pumps work best with thermostats designed for heat pump logic, including emergency heat control and compressor lockout.
Smart integration: Wi Fi enabled controls and home automation can optimize schedules and capture local utility rate structures for savings.

Proper control integration prevents short cycling and supports balanced temperatures across zones.

Post-installation testing and customer walkthrough

After installation a professional will:

Run the system through heating and cooling cycles while measuring temperatures, pressures, and electrical load.
Verify airflow, duct leakage, and thermostat behavior.
Demonstrate system operation, show where filters and access panels are located, and explain basic maintenance tasks.
Provide documentation: equipment model numbers, refrigerant type and charge details, and service procedures.

The walkthrough ensures you understand how to operate and care for your new heat pump.

Warranty information and rebate assistance

Manufacturer and installer warranties: Most heat pumps include a manufacturer warranty on the compressor and parts and a separate workmanship warranty from the installer. Keep documentation and register equipment per manufacturer instructions to secure coverage.
Rebate assistance: California, regional utilities, and local programs often offer rebates or incentive programs for high efficiency heat pumps and electrification projects. A professional installer should help identify eligible programs, provide necessary equipment specifications, and supply paperwork for rebate applications or permit support.

Knowing warranty terms and available incentives is part of making an informed investment.

What to expect on install day in Daly City

Arrival window: Technicians will arrive in a crew with tools and equipment. Expect some noise during mounting, refrigerant work, and electrical connections.
Property protection: Installers should protect floors and landscaping. Rooftop or outdoor unit placement may require ladders or lifts.
Duration: Typical installs take a full day for split or ductless systems; packaged or complex duct modifications may take longer.
Clean up: Professionals will remove packaging and job debris and leave work areas tidy.
Final review: Installer will demonstrate system operation, explain maintenance, and leave warranty and equipment documentation.

Plan for limited access to mechanical areas during work and ensure pets and children are kept clear of work zones.

Benefits and maintenance advice

Benefits: Reliable year round comfort, lower operating costs compared with older electric heating, and reduced greenhouse gas footprint when paired with clean electricity.
Maintenance tips:
Replace or clean filters every 1 to 3 months depending on use.
Keep the outdoor unit free of debris, trim plants to maintain clear airflow, and watch for corrosion in coastal areas.
Schedule annual service checks to verify refrigerant charge and electrical connections.

Heat pump installation in Daly City, CA that starts with a proper site assessment and follows industry best practices delivers long term comfort, energy savings, and resilience to local weather patterns.

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.
