Air Conditioning Installation in Los Gatos, CA

Upgrading to a new air conditioning system is one of the most important home improvements for comfort and energy savings in Los Gatos, CA. With warm, dry summers, occasional inland heat spikes, and seasonal wildfire smoke, a properly sized and installed system improves indoor comfort, indoor air quality, and efficiency. This page walks through the full new AC installation process for Los Gatos homes: site assessment and system selection, ductwork and electrical considerations, the professional installation sequence, code and safety compliance, start-up and commissioning, realistic timelines, maintenance recommendations, and typical customer guarantees.

Why replace or install a new AC in Los Gatos

Older systems lose efficiency and struggle during summer peaks common in Silicon Valley foothills.
Modern heat pump options provide efficient cooling and heating in mild winters.
Newer equipment addresses local indoor air quality concerns such as pollen and wildfire smoke by integrating better filtration and ventilation options.
Upgrading reduces energy bills and helps meet California energy standards.

Common AC installation scenarios in Los Gatos

Replacing a failing central air conditioner with a modern high-efficiency unit.
Installing a ductless mini-split in homes without ductwork or for room-specific cooling.
Converting from an older refrigerant to current refrigerants and equipment that meet California environmental rules.
Adding or resizing ductwork to improve airflow in remodeled or older homes.

Site assessment and system selection

A proper installation begins with a detailed site assessment tailored to Los Gatos homes. Plum HVAC ensures thorough evaluations.

Load calculation (Manual J): Calculates the exact cooling capacity needed based on home orientation, insulation, window area, occupancy, and local climate patterns.
System types: Options include central split systems, packaged units, heat pumps (recommended for energy efficiency and mild heating needs), and ductless mini-splits for zones or homes without ducts.
Efficiency metrics: Look for SEER and HSPF values (higher numbers mean better efficiency). California’s Title 24 and local energy codes influence recommended minimums.
Indoor air quality and filtration: Select systems compatible with upgraded filters, MERV ratings, whole-house ventilation, or UV/air-cleaning options to address pollen and seasonal smoke.
Refrigerant choice: Modern units use approved refrigerants that comply with state and federal regulations. Equipment selection accounts for future serviceability and availability of parts.

Ductwork and electrical considerations

Duct and electrical systems are often the limiting factors in replacement projects.

Duct assessment: Inspect for leaks, insulation gaps, improper sizing, and airflow restrictions. Sealing and insulating ducts improves performance, particularly in attics or crawl spaces typical of Los Gatos homes.
Duct modification or installation: New returns, supply registers, or airflow balancing may be required after installing a higher-efficiency unit or changing system type.
Electrical panel and circuit needs: Many modern units require dedicated breakers and updated disconnects. Older panels in homes may need upgrades to meet current safety and code requirements.
Condensate management: Proper drainage and safety switches prevent moisture damage and mold in attics and ceilings.

Professional installation steps (what to expect)

Installation follows a methodical sequence that prioritizes safety and long-term performance.

Pre-install removal and preparation: Safely remove old equipment, clean the work area, and protect floors and landscaping.
Placement and mounting: Position the outdoor unit on a level pad or bracket; mount indoor components where airflow and access are optimal.
Duct and refrigerant line work: Install or modify duct connections and run refrigerant lines, ensuring proper insulation and support through exterior walls or attic spaces.
Electrical and controls: Install dedicated circuits, disconnects, and thermostat wiring. Integrate smart thermostats or zoning controls if selected.
Refrigerant evacuation and charging: Evacuate air and moisture from the refrigerant lines, then charge to manufacturer specifications for optimal performance.
Condensate and safety installations: Install drainage, overflow protection, and safety float switches where required.

Code, safety, and compliance in Los Gatos

Installations in Los Gatos must comply with California and local codes.

Permits and inspections: Most replacements and new installations require permits and inspection to verify compliance with electrical, mechanical, and energy codes.
Title 24 and energy compliance: California’s energy standards may require specific efficiency levels or commissioning documentation.
Refrigerant handling and environmental rules: Technicians must follow federal and state requirements for refrigerant recovery and disposal.
Wildfire smoke considerations: Code and best-practice approaches recommend enhanced filtration and sealed ducting to reduce smoke infiltration.

Start-up, commissioning, and verification

Thorough start-up ensures the system performs as intended in your home.

System evacuation and leak test: Confirm there are no refrigerant leaks and that the system is correctly charged.
Performance checks: Measure airflow, temperature split, electrical draw, and thermostat calibration to verify efficiency and comfort.
Balancing and zoning: Adjust dampers and registers to ensure even cooling across rooms and correct any pressure imbalances.
Owner orientation: Review filter locations, thermostat settings, and routine checks so the homeowner understands basic operation and care.

Typical timeline for new AC installation in Los Gatos

Timelines vary based on scope and permitting.

Initial assessment and system selection: 1 day on-site plus follow-up.
Permitting: Variable; often a few days to a few weeks depending on municipal schedules and scope of work.
Installation day(s): Simple replacements typically take 1 to 2 days. Full replacements with ductwork modifications or electrical upgrades can take 2 to 5 days.
Final inspection and commissioning: Often occurs within a few days after installation depending on inspector availability.

Maintenance recommendations for longevity and performance

Routine care preserves efficiency and reduces peak-season failures.

Replace or clean filters monthly to quarterly depending on filter type and indoor air quality needs.
Annual or bi-annual tune-up: Check refrigerant charge, clean coils, inspect electrical connections, and lubricate moving parts.
Duct inspection every few years: Seal and insulate as needed.
Summer pre-season check: Test cooling performance before heat waves begin in Los Gatos.

Customer guarantees and performance assurances

A reliable installation program typically includes layered protections.

Manufacturer warranty: Covers parts and compressor for specified periods; registration and proper maintenance preserve coverage.
Workmanship guarantee: Covers installation labor and correct operation for a stated period.
Performance verification: Final commissioning documentation and performance tests demonstrate the system meets the calculated load and efficiency expectations.

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.
