Air Conditioning Maintenance in Los Gatos, CA

Keeping your air conditioning performing reliably through Los Gatos heat and seasonal air quality changes starts with professional, routine maintenance. Regular AC maintenance prevents unexpected breakdowns during summer heat waves, improves indoor comfort in homes near the hills and canyons, and protects equipment from dust, pollen, and wildfire smoke that are common in Santa Clara County. This page explains what thorough AC maintenance includes, common issues in Los Gatos homes, how we diagnose and fix problems, and what a preventative maintenance plan typically covers.

Why routine AC maintenance matters in Los Gatos

Los Gatos experiences warm, dry summers and occasional hot spells that push HVAC systems hard. At the same time, spring pollen and periodic wildfire smoke increase indoor air contaminants. Regular maintenance keeps your system operating efficiently, reduces energy use, extends equipment life, and improves indoor air quality. Well maintained systems also run quieter and provide more consistent temperatures throughout your home, including uphill and valley microclimates common in the area.

Common AC problems in Los Gatos homes

  • Dirty filters and reduced airflow from pollen, dust, and pet dander
  • Clogged condensate lines caused by debris and biological growth, leading to indoor leaks or shut-offs
  • Reduced cooling capacity or long run cycles from low refrigerant or leaks
  • Frozen evaporator coils from airflow restriction or refrigerant problems
  • Inefficient performance from dirty condenser coils or blocked outdoor units (leaves, mulch, or landscaping)
  • Poor thermostat calibration or placement causing uneven comfort
  • Duct leakage or insulation gaps in older Los Gatos homes that lead to higher energy use

What a seasonal tune-up includes

A professional seasonal tune-up is a systematic inspection and service program designed to find and correct small problems before they become major failures. Typical tune-up tasks include:

  • Visual system inspection and safety checks
  • Filter replacement or inspection and recommendations based on indoor air quality and family needs
  • Evaporator and condenser coil cleaning to restore heat exchange efficiency
  • Condensate drain inspection and cleaning to prevent backups and water damage
  • Refrigerant and pressure checks to verify correct charge and detect leaks when pressures are abnormal
  • Airflow checks and fan motor inspection to ensure proper blower operation and static pressure
  • Thermostat calibration and verification of control settings for accurate temperature control
  • Electrical inspection: tightening connections, checking capacitors and contactors for wear
  • Basic system performance test to measure temperature split and run times

Diagnostic and process details explained

  • Filter inspection and replacement: We assess filter type and MERV rating, inspect for dust loading, and replace or recommend a schedule. In Los Gatos, change frequency often increases during pollen season or when smoke events occur.
  • Coil cleaning: Dirty coils reduce cooling capacity and force longer run times. Coil cleaning restores air-to-refrigerant heat transfer. For severe buildup, a soft coil cleaning and fin straightening may be performed.
  • Condensate-line cleaning: Standing water in the condensate pan can lead to mold and a safety float switch shutoff. We clear lines with mechanical snakes, wet-vacs, or safe chemical treatments to restore proper drainage.
  • Refrigerant and pressure checks: Correct refrigerant charge is critical. Low refrigerant often indicates a leak. We measure system pressures and temperature differentials to determine if a recharge or leak repair is needed.
  • Airflow diagnostics: Measuring static pressure and temperature split identifies blocked return vents, dirty coils, or blower issues. Addressing airflow restores cooling efficiency and prevents coil freeze.
  • Thermostat calibration: A miscalibrated thermostat can cause overcooling, short cycling, or uncomfortable rooms. Calibration and strategic thermostat placement help even out temperature across the house.

Common repair solutions and what to expect

  • Refrigerant leak repair and recharge when leak locations are identified; if a leak is significant, repair before recharging to avoid repeated loss.
  • Condensate-line repair or rerouting if poor slope or repeated clogging is found.
  • Condenser fan motor or capacitor replacements when starting or running problems are detected.
  • Evaporator coil repairs or replacement for excessively corroded or damaged coils.
  • Thermostat replacement or upgrade for unreliable control or to support zoning improvements.
  • Duct sealing suggestions when leakage is detected; sealing and insulation can significantly improve comfort in Los Gatos homes with older ductwork.

Preventative inspection checklist (what is reviewed during each visit)

  • Filter condition and replacement status
  • Indoor evaporator coil cleanliness and airflow across coil
  • Outdoor condenser coil condition and clearance around unit
  • Refrigerant pressures and temperature split across evaporator
  • Condensate pan condition and drain line function
  • Electrical connections, contactors, and capacitor health
  • Blower motor and fan operation, belt condition if applicable
  • Thermostat operation and setpoint verification
  • System safety controls and shutoff functions
  • Overall system runtime and performance trend notes

Benefits of regular maintenance for efficiency and longevity

  • Improved energy efficiency and lower monthly cooling bills because systems run less and recover faster.
  • Fewer emergency repairs during peak Los Gatos heat periods.
  • Longer equipment life through reduced mechanical stress and earlier detection of small issues.
  • Better indoor air quality by ensuring filters, coils, and drains are functioning properly—especially important during wildfire smoke or heavy pollen seasons.
  • Preservation of manufacturer warranties that often require documented routine maintenance.

Maintenance plans and scheduling

Maintenance programs typically offer seasonal tune-ups timed for spring and, if desired, fall inspection to prepare heating and cooling systems for off-season storage. Plans usually include scheduled reminders, priority appointment windows during high demand, and documentation of completed service for warranty records. In Los Gatos, homeowners often schedule spring checks before summer and additional checks after major smoke events or pollen peaks. Flexible scheduling accommodates valley and hill microclimates so systems are optimized based on actual local conditions.

Practical tips for Los Gatos homeowners

  • Swap or inspect filters more frequently during wildfire smoke periods and spring pollen season.
  • Keep at least two feet of clearance around outdoor units; trim groundcover and avoid placing mulch against the condenser.
  • Monitor indoor humidity; high humidity reduces comfort and can indicate drainage or airflow issues.
  • Note any unusual sounds, frequent cycling, or uneven cooling and record when these occur to help technicians diagnose problems quickly.

Regular, professional air conditioning maintenance in Los Gatos, CA keeps your home comfortable through changing seasons and protects your investment by maximizing efficiency and minimizing unexpected repairs. Proper maintenance tailored to local climate and air quality factors delivers better performance and longer system life.

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.
