Heating Replacement in Mountain View, CA

Replacing a home heating system is a major decision. In Mountain View, CA, where winters are cool but not severe, a properly sized, high-efficiency system delivers year-round comfort, lower utility bills, and better indoor air quality. This page explains full-system Heating Replacement in Mountain View, CA—from assessing existing equipment and selecting the right model to permitting, HERS/testing coordination, removal, and long-term warranty support—so you can make an informed, confident choice.

Why replace your heating system now? Common heating replacement issues in Mountain View

Homes in Mountain View face specific triggers that make replacement the right move sooner rather than later:

Aging equipment that frequently requires repairs or has declining heating capacity.
Rising energy bills from low-efficiency furnaces or heat systems with poor controls.
Persistent indoor comfort problems like uneven heating, cold spots, or poor airflow.
Transition goals such as moving from gas to electric heat pumps to align with local electrification incentives.
Duct problems, leaks, or undersized distribution systems that limit new system performance.

Recognizing these issues early saves money and prevents mid-season failures. Replacing the whole system is often more cost-effective than repeated component repairs when the unit is outside its expected service life or when you want a step-change in efficiency.

Types of full-system replacements commonly chosen in Mountain View

High-efficiency gas furnaces: For homes currently on natural gas that need a like-for-like replacement with improved AFUE ratings.
Electric heat pump systems: Air-source heat pumps or ductless mini-splits are popular for their efficiency, year-round heating and cooling, and compatibility with California electrification programs.
Hybrid systems: A heat pump paired with a gas furnace provides efficiency for mild days and backup heat for colder conditions.
Ductwork upgrades and replacements: Essential when existing ducts are leaky, undersized, or incompatible with a new system.
Packaged rooftop or attic units: For certain layouts or multi-family buildings where indoor equipment is impractical.

Initial assessment and equipment sizing

A proper replacement starts with a comprehensive assessment of your existing system and home:

Review age, condition, and performance of the current heater and distribution components.
Conduct a Manual J load calculation to determine accurate heating needs based on home size, insulation, orientation, window types, and local climate factors in Mountain View.
Inspect ductwork, registers, and ventilation for leaks, restrictions, or contamination.
Evaluate electrical load and panel capacity for heat pump installations.

Equipment sizing is crucial. Oversized units short cycle and waste energy; undersized units cannot maintain comfort on colder nights. The right-sized system improves comfort, efficiency, and longevity.

Model selection, energy-efficiency, and cost-savings consultation

Choosing the best model involves balancing efficiency, upfront cost, and operating savings:

Compare AFUE for furnaces and HSPF/SEER for heat pumps to estimate long-term savings.
Factor in local Mountain View weather patterns: efficient heat pumps often deliver superior seasonal savings given mild winter temperatures.
Discuss control options like smart thermostats, zoning, and ventilation improvements that reduce operating hours.
Assess available rebates, local utility incentives, and financing options that can materially lower installed cost and payback periods.

This consultation includes projected annual energy savings and a practical estimate of when the efficiency investment pays off in Mountain View’s climate.

Removal, disposal, and installation process

A professional full-system replacement follows a careful, safety-first workflow:

Safely disconnect and remove old equipment and components, following local disposal and recycling regulations.
Prepare the installation site: support pads, electrical upgrades, condensate and venting arrangements, and any duct modifications.
Install new equipment to manufacturer specifications, ensuring proper refrigerant charge for heat pumps and correct venting for combustion appliances.
Seal and insulate ducts, install controls and thermostats, and balance air distribution.
Perform start-up, calibration, and performance verification tests.

Proper removal and disposal in Mountain View must comply with California regulations for refrigerant handling, appliance recycling, and safe disposal of combustion appliances.

Permits, inspections, and HERS/testing coordination

Full-system replacements typically require permits and inspections:

Permits ensure the installation meets California building codes and local Mountain View ordinances.
For electrification projects or major energy efficiency improvements, HERS testing and other performance verification may be required to qualify for state or local incentives.
A coordinated process includes permit submission, scheduling inspections, and providing required documentation such as load calculations and manufacturer specifications.

Handling permits and HERS/testing proactively prevents delays and ensures installations are code-compliant and rebate-ready.

Rebate and financing assistance

Many Mountain View homeowners qualify for state, utility, or local incentives that offset replacement costs:

Rebates may be available for high-efficiency heat pumps, furnace upgrades, duct sealing, and smart controls.
Financing programs can spread out the upfront cost and align payments with projected energy savings.

A replacement plan that factors in rebates and financing options helps make efficiency upgrades more achievable without compromising system quality.

Warranty, post-installation support, and performance verification

Long-term support protects your investment:

Confirm manufacturer and installer warranties and what is covered under each.
Arrange scheduled follow-ups for system verification, thermostat programming, and to confirm performance during the first heating season.
Establish maintenance plans including annual inspections, filter changes, and refrigerant checks to sustain efficiency and reliability.

Post-installation performance verification ensures the system meets the promised efficiency and comfort levels for Mountain View homes and provides documentation useful for future resale.

Maintenance tips and long-term benefits

After replacement, simple maintenance preserves performance and savings:

Replace or clean filters regularly and maintain clear outdoor units for heat pumps.
Program thermostats for setback periods and use zoning to avoid heating unused spaces.
Schedule annual tune-ups and duct checks.

Benefits you can expect in Mountain View after a properly executed heating replacement include improved indoor comfort, predictable energy bills, lower operating costs, and a modern system tailored to local climate and code 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.

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.

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.
