Heating Replacement in Daly City, CA

Replacing a home heating system is a significant decision that affects comfort, energy bills, and indoor air quality. For Daly City homeowners, coastal climate, older housing stock, and local efficiency regulations make thoughtful evaluation essential. This page explains when a heating replacement is recommended, how existing equipment and ductwork are assessed, sizing and efficiency options, model comparisons, removal and disposal, permit and inspection coordination, rebate and financing assistance, warranty considerations, and realistic project timelines and expectations.

When to consider a heating replacement in Daly City

Common heating replacement issues in Daly City include aging furnaces or heat pumps, frequent repairs, uneven heating in homes with older ductwork, and poor cold-weather performance during foggy, chilly nights. Consider replacement when you see one or more of the following:

  • System age over 12 to 15 years for furnaces or older heat pump models
  • Increasing repair frequency and rising service costs
  • Rising energy bills without usage changes
  • Inconsistent rooms temperatures or persistent drafts
  • Safety concerns such as cracked heat exchangers or gas odor
  • Desire to switch to cleaner, electric heat-pump technology to reduce carbon footprint and utility dependence

Evaluation of existing equipment and ductwork

A thorough evaluation precedes any replacement decision. The assessment typically includes:

  • Visual inspection of the furnace or heat pump, burners, heat exchanger condition, and electrical components
  • Measuring operating efficiency and reviewing service history
  • Ductwork inspection for leaks, insulation levels, sizing, and airflow balance
  • Combustion safety checks for gas systems, including venting and flue integrity
  • Home envelope review: insulation levels, window performance, and common heat loss paths

In Daly City, many homes are older and may have undersized or leaky ducts. Sealing and insulating ducts or making targeted air-sealing and insulation upgrades can improve comfort and reduce required system size.

System sizing and energy-efficiency options

Correct sizing is critical. Oversized systems cycle frequently and reduce comfort; undersized systems fail to keep up. Sizing is done using a load calculation that considers:

  • Home square footage and orientation
  • Insulation, window types, and air infiltration
  • Local climate patterns in Daly City, including coastal cooling and night-time temperature drops

Efficiency and technology choices:

  • High-efficiency condensing gas furnaces with higher AFUE ratings for homes that remain on gas
  • Air-source heat pumps and cold-climate heat pumps for efficient electric heating and cooling in mild coastal climates
  • Dual-fuel systems that combine a heat pump with a gas furnace for optimal winter performance and efficiency
  • Variable-speed blowers and modulating compressors for better comfort and lower energy use

Choosing higher-efficiency equipment often reduces operating costs and may qualify for state and local incentives.

Comparing model types: furnace vs heat pump vs hybrid

When evaluating models for Heating Replacement in Daly City, CA, compare these categories:

  • Gas furnace: reliable heat output in cold snaps, but combustion safety and venting must be maintained
  • Air-source heat pump: excellent efficiency in mild coastal climates, provides both heating and cooling, and reduces on-site combustion
  • Cold-climate heat pump: designed to maintain efficiency at lower temperatures and a good fit for households aiming to move away from gas
  • Hybrid systems: heat pump primary with furnace backup for peak cold periods

Compare models on efficiency ratings (AFUE for furnaces, HSPF and SEER for heat pumps), sound levels, physical footprint, and controls (thermostat compatibility, zoning capability).

Removal and disposal of old equipment

Replacement includes safe removal and responsible disposal of the old system:

  • Disconnect utilities and remove equipment according to code and safety standards
  • Properly dispose of refrigerants from heat pumps and reclaim or neutralize as required
  • Recycle metal and other materials when possible; handle gas furnaces and oil tanks with appropriate safety measures
  • Restore any penetrations or finishes disrupted during removal

In coastal areas like Daly City, technicians also check for corrosion from salt air and address any compromised components.

Permit and inspection coordination

Permits and inspections ensure safety and compliance with California and Daly City codes. Typical permit needs:

  • Mechanical permit for replacing HVAC equipment
  • Gas line permits for new connections or modifications
  • Electrical permit for significant wiring changes
  • Final inspection to verify proper installation, venting, combustion safety, and energy compliance

Installations must meet state energy standards and local ordinances. Coordinate timing for permit submission and inspections to avoid project delays.

Rebate, incentive, and financing assistance

Many Daly City homeowners can access incentives that lower the net cost of replacing heating systems:

  • State and regional energy rebate programs for high-efficiency heat pumps and electrification measures
  • Utility rebates and programs through the local electric and gas providers that encourage efficient equipment and weatherization
  • Local Bay Area decarbonization and electrification incentives for qualifying projects

Financing options to consider:

  • Low-interest HVAC loans and payment plans offered through equipment providers or third-party lenders
  • Property assessed financing programs in California that allow energy improvements to be paid over time
  • Manufacturer and utility-supported financing offers that help spread costs

Eligibility and program availability change over time. Documentation and properly permitted installations are commonly required for incentive approval.

Warranty details and what they mean for you

Two warranty types matter:

  • Manufacturer warranty: covers defects in components and typically ranges from a limited parts warranty to longer warranties for specific parts like compressors or heat exchangers
  • Installer warranty: covers workmanship and installation-related issues and varies by provider

When comparing options, document the length of both warranties, what they cover, any registration requirements, and how warranty service is handled. In California, confirm that warranty and service procedures align with state regulations.

Project timeline and what to expect

Typical project timelines for Heating Replacement in Daly City, CA:

  • Evaluation and proposal: 1 to 7 days
  • Permit processing: a few days to several weeks depending on permit load and scope
  • Installation: 1 to 3 days for like-for-like equipment; 3 to 7 days or more for ductwork upgrades, electrical changes, or complex retrofits
  • Final inspection and system commissioning: add 1 to 7 days for scheduling

What to expect during the job:

  • Clear access to the equipment and attic or crawlspace as needed
  • Professional installation with testing for airflow, combustion safety, and thermostat calibration
  • Minimal disruption when planned well; containment for dust and debris in sensitive areas
  • Documentation provided at completion: equipment manuals, efficiency ratings, warranty registration information, and maintenance recommendations

Long-term benefits and maintenance

A properly executed replacement improves comfort, reduces energy use, and increases home value. In Daly City, switching to a high-efficiency or heat-pump system can mean better year-round comfort in a mild coastal climate and alignment with local electrification trends. Regular maintenance—annual tune-ups, filter changes, and periodic duct inspections—protects performance and warranty coverage.

This overview equips you to evaluate the full scope of a heating replacement in Daly City, CA, from diagnosis to post-installation care. A well-planned replacement balances equipment selection, energy savings, code compliance, and long-term reliability for your 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.
