Heating Replacement in Woodside, CA

Replacing a home heating system is a major decision for Woodside homeowners. With our mild but sometimes chilly Bay Area winters, variable microclimates, and a local focus on energy efficiency and electrification, selecting the right replacement affects comfort, indoor air quality, long-term energy bills, and home value. This page explains the full heating replacement process for Woodside homes: how technicians assess your system, how equipment is sized and selected, what to expect during removal and installation, permitting and inspection requirements, timelines, financing and rebate considerations, and warranty options so you can choose with confidence.

Why replace your heating system now

  • Older systems lose efficiency, cycle frequently, and can create uneven temperatures in homes built on hills or with multiple levels common in Woodside.
  • Safety concerns: cracked heat exchangers, combustion issues, and elevated carbon monoxide risk are reasons to replace sooner rather than later.
  • Electrification trend and efficiency standards in California make high-efficiency heat pumps or condensing gas furnaces attractive for lower long-term operating costs and reduced emissions.
  • Replacement can improve home resale appeal in an area where buyers expect modern, efficient systems.

Initial assessment: what technicians check

A thorough replacement begins with a detailed on-site evaluation:

  • Visual inspection of the existing furnace or heat pump and the outdoor unit if present.
  • Combustion safety and carbon monoxide testing for gas systems.
  • Airflow measurements at registers and return grilles to detect blockages or undersized ductwork.
  • Duct inspection for leaks, insulation level, and routing challenges typical in older Woodside homes.
  • Thermostat type and wiring compatibility.
  • Review of attic, crawlspace and mechanical closet clearances and structural constraints that affect equipment placement.
  • Discussion of comfort goals, budget, and preference for electrification vs gas options.

Accurate sizing and system selection

Proper sizing prevents short cycling, poor comfort, and wasted energy:

  • Technicians perform a heat load calculation (industry-standard Manual J). This accounts for Woodside home characteristics: square footage, orientation, insulation levels, window types, and the local climate, including nighttime cooling from coastal fog and daytime sun exposure.
  • Duct design (Manual D) is reviewed; some homes need duct resizing or modification to accommodate higher-efficiency systems.
  • Equipment selection (Manual S) matches a properly sized furnace or heat pump to your home and comfort goals.

Common replacement options explained

  • High-efficiency gas condensing furnace: good for homes where gas remains preferred; offers higher AFUE and better control than older furnaces.
  • Air-source heat pump: efficient all-electric option that provides heating and cooling, increasingly effective in mild Bay Area winters. Modern cold-climate heat pumps handle lower temperatures better than older models.
  • Ductless mini-splits: ideal for room-by-room comfort upgrades or homes without viable ductwork.
  • Hybrid systems: pairing a heat pump with a gas furnace for backup can optimize efficiency and comfort in certain situations.

Removal, disposal, and environmental compliance

  • Technicians recover refrigerant from heat pumps following California regulations and EPA refrigerant handling requirements.
  • Gas lines are capped and tested for leaks; combustion appliances are disconnected with attention to venting and chimney closure if needed.
  • Old equipment is removed and disposed of responsibly. Components containing hazardous materials (refrigerant, oil, PCBs in older ballasts) are handled per state and local disposal rules.
  • Proper documentation of disposal and refrigerant recovery is provided for permit compliance and potential rebate program requirements.

Permits, inspections, and local considerations

  • Heating replacement generally requires a building or mechanical permit in Woodside and San Mateo County. Permits ensure installations meet local code, safety, and ventilation requirements.
  • Inspections may include rough mechanical inspection for gas piping or duct changes and final inspection for combustion safety, electrical connections, and overall installation compliance.
  • In some neighborhoods, historical or hillside constraints can affect equipment placement. Technicians familiar with Woodside regulations will account for these when proposing options.

Typical timeline for replacement

  • On-site assessment and load calculations: 1 to 2 site visits.
  • Permit approval: varies by jurisdiction and scope; often a few days to a couple of weeks.
  • Installation: straightforward like-for-like replacements are commonly completed in 1 to 2 days. Installations involving ductwork changes, new pad or condenser location, or electrical upgrades can take 2 to 5 days.
  • Final inspection: scheduled after installation; timeframe depends on local inspector availability.

Cost factors and financial considerations

Instead of a generic price, focus on the variables that determine cost:

  • System type and capacity (heat pump, furnace, ductless, hybrid).
  • Extent of ductwork repair, replacement, or sealing.
  • Necessary electrical upgrades for heat pumps, especially older homes with limited service capacity.
  • Venting or gas line modifications for new furnaces.
  • Accessibility and site work for outdoor units or new equipment pads.

Financing and rebates

  • Many Woodside homeowners qualify for local, state, or utility incentive programs and financing options that lower upfront costs for energy-efficient equipment and electrification upgrades. Incentives often favor heat pumps and high-efficiency equipment.
  • Eligibility typically depends on equipment efficiency ratings, installation by certified contractors, and following program-specific documentation and inspection steps.
  • Discuss available rebate and financing paths with your technician early so paperwork and equipment selection align with program requirements.

Warranties and long-term protection

  • Manufacturer warranties cover major components like compressors, heat exchangers and coils. Typical manufacturer coverage varies by product and brand.
  • Labor warranties cover installation workmanship for a defined period; extended labor protection may be available.
  • Warranty registration and regular maintenance are often required to keep warranties valid. Save installation paperwork and warranty certificates.
  • Consider service plans that include annual tune-ups to maintain efficiency and detect early issues.

Aftercare and maintenance tips

  • Replace or clean filters on the manufacturer-recommended schedule to sustain airflow and efficiency.
  • Schedule annual or biannual tune-ups: combustion analysis for gas systems or refrigerant and electrical checks for heat pumps.
  • Seal and insulate ducts where accessible to reduce distribution losses common in older Woodside homes.
  • Upgrade thermostats to programmable or smart models for better comfort control and energy savings that respond to local temperature patterns.

What to expect from a professional replacement

A competent replacement focuses on safety, comfort, efficiency and compliance with Woodside and San Mateo County regulations. Expect a clear assessment, properly sized equipment based on a heat load calculation, transparent documentation for permits and rebates, environmentally responsible removal of old equipment, and a written summary of warranties and maintenance needs. The right solution balances immediate comfort improvements with long-term operating costs and environmental goals for your Woodside home.

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.
