Ductwork Installation in Burlingame, CA

Ductwork Installation in Burlingame, CA is a critical investment in comfort, energy efficiency, and indoor air quality for your home. Whether you are building new construction, replacing an aging system, or retrofitting ducts into a Bay Area bungalow, a properly designed and installed duct system ensures consistent temperatures, lower energy bills, and fewer comfort complaints. In Burlingame homes, local climate, older framing, and code requirements shape the choices for materials, routing, and testing.

Common ductwork projects in Burlingame homes

  • New construction duct systems sized to modern HVAC equipment
  • Retrofit ductwork for historic or constrained homes with limited attic or crawl space
  • Replacement of corroded or leaky ducts affected by coastal air
  • System redesigns to improve airflow balance and eliminate hot or cold rooms
  • Upgrades to insulated ducts and improved sealing to meet California energy standards

Why local conditions matter

Burlingame has mild, coastal-influenced weather with seasonal fog and higher humidity. That affects duct choices in several ways:

  • Humidity and moisture increase the risk of mold inside poorly insulated or wet ducts; insulation and vapor barriers become more important.
  • Salt air near the bay can accelerate corrosion on unprotected metal ducts; galvanized steel or protective finishes are recommended.
  • Many Burlingame homes are older or have compact floor plans, making custom routing and space-saving configurations necessary.

System design and load calculations

A reliable ductwork installation begins with accurate system design and load calculations. Proper design includes:

  • Performing a full heating and cooling load calculation using industry standards to determine equipment capacity and airflow needs.
  • Mapping duct runs to match the house layout, room-by-room load requirements, and the selected HVAC unit.
  • Sizing supply and return trunks and branch runs so each room receives the correct cubic feet per minute (CFM).
  • Considering static pressure limits of the selected equipment to prevent noisy operation or reduced capacity.

Accurate design reduces energy waste, prevents short-cycling, and avoids common retrofit mistakes like undersized returns or overly long flexible runs.

Materials and insulation options

Choosing the right materials and insulation affects longevity, performance, and indoor air quality.

  • Galvanized sheet metal: Durable, low-leak when sealed properly, and resistant to most corrosion when specified with proper coatings.
  • Aluminum: Lightweight and corrosion resistant, useful in coastal environments.
  • Flexible duct: Good for short, simple runs and tight spaces; must be installed without excessive bends or compression to avoid airflow losses.
  • Duct board: Provides integrated insulation and sound damping but requires careful sealing to avoid fiber shedding.

Insulation considerations:

  • Use insulation with an appropriate R-value and a continuous vapor barrier for attic and exterior runs. In Burlingame, R-values and vapor control help limit condensation during cool, humid mornings.
  • Consider foil-faced insulation or insulated spiral duct for exposed areas to reduce thermal loss.
  • Ensure all seams and joints are sealed with code-approved mastic or metal-backed tape rather than cloth or duct tape.

Custom fabrication and routing for new and retrofit projects

  • In new construction, ducts can be centrally located and sized optimally. Custom-fabricated trunks and transitions help ensure efficient airflow.
  • For retrofit projects, expect creative routing: using soffits, closets, conditioned attic space, or small basement areas to minimize invasive work.
  • Custom transitions, boots, and boots with adjustable dampers help balance airflow when space forces nonstandard runs.
  • Address noise concerns by specifying smooth profiles where possible and isolating ductwork from framing with vibration-damping hangers.

Code compliance and permitting

Ductwork Installation in Burlingame, CA must comply with California building and energy codes.

  • Designs typically must meet California Title 24 energy requirements for duct sealing, insulation, and efficiency labeling.
  • Permit requirements are managed by the City of Burlingame building department; retrofits and system replacements often require mechanical permits and inspections.
  • Typical code elements: minimum R-values for insulated ducts, verified duct leakage limits, and accessible returns/filters.
  • Expect documentation of load calculations, material specs, and test results as part of permitting and final inspection.

Timeline and pricing expectations

Typical timelines vary with scope:

  • Simple replacements or direct swaps: a day to a few days.
  • Whole-house new installations or extensive retrofits: several days to a few weeks depending on access, custom fabrication needs, and permit turnaround.

Pricing is influenced by:

  • House size and layout complexity
  • Degree of access (attic, crawlspace, finished ceilings)
  • Material choices (metal vs flexible vs duct board)
  • Extent of necessary structural work or drywall repair after routing
  • Required permits and inspection fees

Providing clear estimates based on a site survey and load calculation helps set accurate expectations and reduces surprises.

Post-installation testing and commissioning

Testing confirms the system meets design performance:

  • Leak testing checks for duct air loss using pressurization methods; sealed systems conserve energy and improve comfort.
  • Air balance testing measures and adjusts CFM to each supply and return so rooms receive the intended airflow.
  • Static pressure checks ensure the system operates within manufacturer limits to avoid noise and equipment strain.
  • Inspectors may require documentation showing duct leakage and balancing results to satisfy Title 24 or local permitting requirements.

Warranty and maintenance recommendations

For long-term performance and to protect your investment:

  • Verify manufacturer and installer warranties on labor and materials. Understand what is covered and for how long.
  • Schedule annual inspections focused on seal integrity, insulation condition, condensation issues, and airflow balance.
  • Replace filters regularly and inspect return grilles for blockage to maintain designed airflow.
  • Consider periodic duct cleaning only if there is evidence of contamination, pests, or significant dust buildup; cleaning should be done by qualified professionals using containment methods.
  • Repair or reseal any connections showing deterioration, and refresh insulation or protective coatings for metal ducts exposed to coastal conditions.

Benefits of doing ductwork right the first time

A professionally designed and installed duct system in Burlingame translates into:

  • More consistent comfort across rooms and floors
  • Lower energy consumption and improved HVAC lifespan
  • Better indoor air quality and reduced moisture-related issues
  • Fewer callbacks and long-term repair expenses

Well-documented design, permitting, and testing not only meet local requirements but also provide owners with confidence that their system was installed to perform reliably in Burlingame’s specific climate and housing stock.

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.

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.
