Heating Installation in Redwood City, CA

Upgrading or installing a new heating system is a major home improvement decision. In Redwood City, CA, where winters are mild but damp coastal air can make indoor comfort challenging, a properly sized and professionally installed heating system delivers reliable comfort, lower energy bills, and better indoor air quality. This page explains the full heating installation process from site assessment and sizing to warranty registration, and describes what homeowners can expect on install day.

Why a professional heating installation matters in Redwood City, CA

Redwood City homes face specific factors that affect heating performance: generally mild winter temperatures, occasional cold nights, high humidity and marine layer influence, and local building code requirements in the Bay Area. These conditions mean that equipment choice, system sizing, ductwork condition, and proper commissioning matter more than simply picking a higher-capacity unit. Correct installation maximizes comfort, efficiency, and system lifetime while ensuring compliance with local inspections and HERS testing when applicable.

Common heating installation issues in Redwood City homes

  • Undersized or oversized equipment leading to short cycling, higher utility costs, and uneven temperatures
  • Poorly sealed or leaking ducts that reduce delivery of warm air and increase run times
  • Incompatible or poorly placed thermostats causing inaccurate readings and inefficient control
  • Improper refrigerant charge or airflow on heat pumps that reduces efficiency and longevity
  • Condensate or venting problems with high-efficiency furnaces or boilers in damp coastal climates
  • Missed permits or incomplete coordination with city inspections and HERS verification when required

Site assessment and sizing

A professional installation begins with a thorough site assessment and accurate load sizing. This includes:

  • A Manual J load calculation to determine exact heating demand based on home size, orientation, insulation, window types, and Redwood City-specific climate data
  • Inspection of ductwork, vents, insulation, and attic or crawlspace conditions to identify required repairs or upgrades
  • Evaluation of fuel sources and utilities available on site, for example natural gas lines, electrical capacity for heat pumps, and routing for condensate or flue vents
  • Discussion of comfort goals, budget, and long-term energy plans such as electrification or solar-ready systems

Accurate sizing prevents common problems like short cycling, excessive noise, and inefficient operation that are especially noticeable in smaller, energy-efficient Bay Area homes.

Recommended equipment selection

Equipment selection balances comfort, durability, and efficiency. Common options for Redwood City installations include:

  • High-efficiency gas furnaces with appropriate AFUE ratings for homes with existing gas service
  • Electric heat pumps or ductless mini-split heat pumps that provide efficient heating and cooling and align with regional electrification trends and available rebates
  • Boilers for hydronic systems where radiant heat or existing boiler infrastructure is present
  • Hybrid systems that pair heat pumps with gas furnaces for cold snaps and optimal year-round efficiency
  • Smart or programmable thermostats for zoning and better control

Selection factors include equipment capacity from the load calculation, AFUE/SEER/HSPF ratings, existing ductwork condition, and homeowner goals for efficiency and electrification.

Step-by-step installation workflow

A clear, methodical installation workflow protects your home and ensures code compliance:

  1. Pre-install coordination: finalize equipment, order materials, apply for required permits, and schedule inspection windows and any HERS testing.
  2. Site preparation: protect floors, furniture, and landscaping; turn off utilities as needed; remove old equipment safely and dispose of it responsibly.
  3. Rough-in work: frame or platform for new equipment, run new refrigerant or gas lines, install venting or condensate piping, and make electrical connections to code.
  4. Ductwork and distribution work: repair, reseal, insulate, or modify ducts, add returns or supply registers if needed, and install zoning dampers when required.
  5. Equipment installation: set and secure the new unit, connect refrigerant lines and charge if a heat pump, connect combustion venting for furnaces or boilers, and install the thermostat.
  6. Coordination with inspections: schedule city or county mechanical, gas, and electrical inspections. If HERS testing is required for performance compliance, coordinate with a certified HERS rater.
  7. Commissioning and performance verification: see next section.
  8. Final cleanup and customer walkthrough: ensure the site is clean, provide documentation, and register warranties.

Install timelines vary. Simple furnace swaps can be completed in a single day, while larger heat pump conversions, duct upgrades, or zoning projects may take multiple days.

Commissioning and performance verification

Commissioning verifies the system operates as designed and delivers expected performance. Key steps include:

  • Measuring supply and return temperatures, airflow, and static pressure to confirm proper airflow and balancing
  • Refrigerant charge verification and superheat/subcooling checks on heat pumps to optimize efficiency
  • Combustion analysis and flue inspection for gas systems to ensure safe and efficient operation
  • Thermostat calibration and zoning checks to confirm temperature control and setbacks work properly
  • Leak testing and blower door or duct leakage testing when required by code or HERS protocols

For many projects in California, HERS testing is required for new construction or significant system replacements to verify energy code compliance. A certified HERS rater will conduct tests like duct leakage measurement and HVAC system verification and provide the official report needed for final approvals.

Coordination with inspections and HERS testing

Redwood City installations must comply with local building and energy codes. Typical coordination includes:

  • Obtaining mechanical, electrical, and gas permits before work begins
  • Scheduling inspections at rough-in and final stages with the city or county building department
  • Arranging HERS testing when required, and providing necessary documentation for the rater
  • Addressing any corrective items noted by inspectors or the HERS rater in a timely manner to finalize approvals

Proactive coordination prevents delays and ensures your system meets all safety and energy requirements.

Warranty registration and documentation

After commissioning, registering manufacturer warranties and documenting labor guarantees protects your investment. Typical steps include:

  • Submitting manufacturer warranty registration to activate coverage for parts and optional extended warranties
  • Providing a clear record of installation date, model and serial numbers, and work performed
  • Supplying owner manuals, maintenance tips, and seasonal checklists for long-term reliability

Registered warranties are often required for certain rebates or incentives available in the Bay Area, so accurate documentation matters.

What to expect on install day

On install day you should expect a professional, organized process:

  • Arrival window and identification by technicians; technicians will use protective coverings and take measures to minimize dust and disruption
  • Removal of the old unit, site cleanup, and confirmation of the planned work scope before starting major steps
  • Communication about any unexpected findings such as degraded ductwork or structural issues and how those will be handled
  • A realistic timeline for major milestones that day and an estimate if additional work will extend the project
  • A final system demonstration showing how to operate the thermostat, select modes, and basic troubleshooting tips, plus delivery of warranty and inspection paperwork

Long-term benefits and maintenance advice

A professionally installed system delivers consistent comfort, lower operating costs, and longer equipment life. To maintain performance:

  • Schedule annual tune-ups, including filter changes, airflow checks, and refrigerant or combustion testing
  • Keep outdoor units clear of debris and ensure proper drainage during rainy months
  • Consider duct sealing and insulation upgrades to improve efficiency, especially in older Redwood City homes
  • Use programmable or smart thermostat schedules to reduce energy use during unoccupied hours

Proper maintenance and prompt attention to minor issues prevent costly repairs and preserve warranty coverage.

ConclusionHeating installation in Redwood City, CA requires careful attention to sizing, equipment choice, ductwork condition, and code compliance. A methodical approach covering site assessment and sizing, recommended equipment selection, step-by-step installation workflow, coordination with inspections and HERS testing, commissioning and performance verification, and warranty registration ensures a comfortable, efficient system tailored to local climate and building requirements.

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.)

Marlene S.

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.

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.
