Common HVAC issues in Los Gatos homes

Los Gatos homeowners often face specific HVAC challenges due to local climate and housing stock:

Air conditioners struggle during prolonged heat waves or when refrigerant is low.
Older furnaces or heat pumps that were not sized for modern insulation upgrades cycle frequently or deliver uneven heat.
Leaky, uninsulated ductwork in older homes reduces efficiency and comfort.
Indoor air quality problems during wildfire season: smoke infiltration and increased particulate levels.
Thermostats and zoning systems that are outdated or improperly configured, causing hot and cold spots.
Short cycling, rising energy bills, and noisy equipment from deferred maintenance.

Diagnostic process: how proper service starts

A reliable HVAC Company in Los Gatos, CA follows a structured diagnostic and assessment process:

Site assessment: inspect equipment, duct layout, insulation, and indoor air quality conditions in your home.
Load sizing: perform heat load and cooling load calculations to determine correct equipment capacity for your home’s layout and occupancy.
System evaluation: check refrigerant charge, airflow, electrical connections, combustion safety (for gas appliances), and control wiring.
Recommendations: present equipment options with expected performance, efficiency ratings, and compatibility with existing ductwork or zones.
Written scope: provide a transparent scope for installation, replacement, or repair, including any necessary duct modifications or indoor air quality upgrades.

Installation and commissioning: what to expect

Professional installation is critical to system performance and warranty compliance. Key installation steps include:

Proper equipment selection based on load calculations and local climate needs, not just square footage.
Ductwork sizing, sealing, and insulation to minimize losses and improve comfort.
Correct refrigerant charging and airflow balancing to meet manufacturer specifications.
Thermostat and zoning setup for precise control and energy savings.
Commissioning and performance verification: final testing, safety checks, and documentation of performance metrics.

Repairs and common solutions

Air conditioning repair: refrigerant leaks, compressor replacement, capacitor or motor repairs, and condenser coil cleaning.
Heating repair: ignition and control repairs, heat exchanger inspection, circulating blower service, and reversing valve service for heat pumps.
Duct and airflow fixes: sealing leaks, adding insulation, repairing disconnected runs, and balancing registers.
Controls and thermostats: replacing old thermostats with smart or programmable models and troubleshooting wiring issues.
Air quality measures: installing higher-efficiency filters, whole-home purifiers, and ERV systems to address wildfire smoke and seasonal allergens.

Preventative maintenance and seasonal tune-ups

Regular maintenance keeps systems running efficiently and prevents costly breakdowns:

Spring A/C tune-up: clean coils, check refrigerant, inspect electrical connections, and test performance before cooling season.
Fall heating tune-up: test ignition systems, inspect heat exchangers, clean burners, and verify safety controls.
Maintenance plan benefits: lower energy costs, fewer emergency repairs, extended equipment life, and prioritization during peak demand.
Maintenance also helps preserve manufacturer warranties that require documented professional service.

Warranties, licensing, rebates and financing

Licensed, insured technicians who work to local California codes protect safety and compliance. Many HVAC systems come with manufacturer warranties that require certified installation and documented maintenance. Los Gatos homeowners may qualify for local and state energy-efficiency rebates and incentives, including utility programs. Financing assistance options are commonly available to spread upgrade costs for high-efficiency systems or comprehensive replacements.

FAQs — quick answers for Los Gatos homeowners

How often should I schedule tune-ups? Twice yearly is recommended: once before cooling season and once before heating season.
Do I need duct sealing? If your home is older or shows uneven temperatures, duct sealing can improve comfort and reduce utility costs.
Is a heat pump a good option in Los Gatos? Yes. Modern heat pumps are efficient in our mild climate and provide both heating and cooling.
How do I improve indoor air quality during wildfire smoke? Upgrading to higher MERV filters, adding whole-home purifiers, and minimizing outdoor ventilation during heavy smoke days help significantly.
How is system size determined? A professional load calculation considers insulation, window types, orientation, occupancy, and local climate—not just home size.

Long-term benefits of professional HVAC care

Properly selected and installed HVAC systems deliver consistent comfort, lower monthly bills, improved indoor air quality, and fewer emergency repairs. In Los Gatos, where seasonal temperature swings and air quality incidents occur, investing in appropriate equipment and maintenance improves resilience and home value. Regular service preserves equipment life and supports warranty coverage, while energy-efficient upgrades often qualify for rebates and can reduce environmental impact.

Keeping your HVAC system tuned, safe, and matched to your home ensures comfort through summer heat, winter cool spells, and periods of poor air quality. If you want accurate assessments and solutions built for Los Gatos homes, focus on licensed professionals who prioritize load-based sizing, quality installation, and ongoing maintenance.

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.

Plum HVAC is an extremely professional, knowledgeable, and an established company to hire. I highly recommend Plum HVAC! Sam and his crew did a wonderful job. Sam worked with my schedule and his crew had completed the job with ease.

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.
