Ductless mini-split systems have become a go-to option for Mountain View homes and small businesses looking for efficient, targeted heating and cooling without the need for full ductwork.

Why Choose Ductless Mini-Splits in Mountain View

Zoned comfort: Multiple indoor units on one outdoor compressor allow precise temperature control in bedrooms, living areas, or home offices without conditioning empty rooms.
High energy efficiency: Inverter-driven compressors and high SEER/HSPF ratings deliver energy savings versus older window units or inefficient furnaces.
Ideal for retrofits: Older homes or properties with limited attic space benefit from small wall penetrations instead of extensive ductwork.
Improved indoor air quality: Built-in filtration reduces dust and particulates — useful during local construction or wildfire smoke events.
Quiet operation and space savings: Compact indoor heads suit home offices and media rooms common in the Bay Area.

Site Assessment and Multi-Zone Design

A thorough assessment ensures reliable installation and optimal performance:

Perform a heat load calculation considering home orientation, insulation, windows, occupancy, and Mountain View’s local climate.
Map indoor unit locations for airflow, comfort, and aesthetics (wall-mounted or ceiling cassette options).
Design multi-zone layouts based on daily use patterns (e.g., separating upstairs bedrooms from ground-floor living spaces).
Evaluate outdoor unit placement to minimize noise, maximize airflow, and consider sun exposure and winds.
Plan refrigerant line routing, electrical connections, and condensate drainage with minimal visual impact.

Local considerations: Solar panel placement, proximity to busy streets, microclimates from nearby hills or water, and home offices or server rooms requiring stable temperatures.

Professional Installation Steps

Finalize indoor unit positions and mark wall penetrations.
Create properly sealed refrigerant and condensate penetrations.
Mount indoor units and outdoor condenser on vibration-isolating brackets.
Run refrigerant lines, insulation, and electrical wiring; evacuate and charge refrigerant.
Connect controls and set up zone controllers or smart thermostats.
Test each zone for airflow, temperature response, and refrigerant pressures; balance settings.
Provide a user walkthrough for filters, controls, and maintenance.

Note: Permits and inspections are required in Mountain View and Santa Clara County. Installations follow local codes for electrical and refrigerant handling.

Routine Maintenance and Tune-Ups

Regular maintenance preserves efficiency and extends system life:

Clean or replace washable and disposable filters.
Inspect and clean indoor coils and blower fans.
Check refrigerant levels and inspect for leaks.
Clear condensate drains and verify proper drainage.
Inspect outdoor unit fins and remove debris.
Verify electrical connections and control calibration.
Update firmware or settings for smart units.

Tip: Maintenance is especially important after periods of heavy use, construction dust, or wildfire smoke.

Common Issues and Repairs

Refrigerant leaks: Reduced cooling or frosting; repaired by certified leak detection and recharge.
Compressor or outdoor unit failures: Diagnosed for component repair or replacement.
Frozen indoor coils: Caused by restricted airflow or low refrigerant; service restores airflow and charge.
Electrical faults/control issues: Intermittent operation, tripped breakers, or faulty remotes addressed at control board.
Drain clogs/water leaks: Condensate lines cleared and sanitized to prevent overflow.

Local challenges: Tight access in older homes and compliance with refrigerant regulations.

Energy-Efficiency Considerations

When sizing and selecting a mini-split, prioritize:

Correct sizing: Avoid oversizing, which causes short cycling and reduces comfort.
Inverter technology: Variable-speed compressors adjust output to demand, lowering energy use.
High SEER/HSPF ratings: Maximize energy savings in the Bay Area climate.
Smart controls & scheduling: Zoned setpoints and occupancy-based schedules reduce wasted energy.
Solar integration: Mini-splits pair well with rooftop solar for lower carbon operation.

Result: Properly installed and maintained mini-splits often reduce energy use compared to older central systems with duct losses.

Examples and Outcomes

Retrofit bungalow: Two-zone mini-split replaced a patchy duct system; result: even temperatures across floors, elimination of duct cleaning, improved bedroom comfort.
Multi-zone condo: Four indoor heads on one outdoor unit; result: quieter operation, targeted cooling for home offices, reduced shared utility load.
Garage workshop: Wall-mounted mini-split provided year-round comfort without ducts; result: consistent workspace temperature, improved equipment longevity.

Typical outcomes: Faster temperature recovery, quieter operation, and noticeable energy savings when properly maintained.

Summary

Mini split services in Mountain View, CA provide:

Targeted comfort across multiple zones.
Energy-efficient heating and cooling.
Flexible installations for homes and small businesses.
Routine maintenance and prompt repairs for long-term reliability.

With careful planning, professional installation, and ongoing service, mini-splits deliver reliable, cost-effective comfort while addressing local challenges such as retrofit constraints, seasonal dust, and the Bay Area focus on electrification.

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.
