Common HVAC issues in Santa Clara, CA

Understanding frequent problems helps you choose the right service:

Insufficient cooling on hot days: Often caused by low refrigerant, dirty coils, or undersized systems that struggle during peak summer heat.
High energy bills: Poorly maintained equipment, duct leakage, or outdated systems lower efficiency and increase costs.
Weak or uneven airflow: Leaky, blocked, or improperly sized ducts and failing blower motors create hot and cold spots.
Frequent cycling or short cycling: Compressor or control issues can cause systems to start and stop too often, reducing system life.
Noisy operation: Loose components, worn bearings, or failing blowers create disruptive noises.
Indoor air quality problems: Wildfire smoke, pollen, and urban pollutants increase demand for filtration and ventilation improvements.
Thermostat or control failures: Incorrect settings or failing controls reduce comfort and cause unnecessary runtime.

These issues are amplified by Santa Clara factors: hotter-than-average summer days, seasonal shifts between outdoor smoke events and clear air, and many homes with older ductwork or mixed HVAC systems.

Our service process: assessment, sizing, professional installation, testing

A well-executed process makes the difference between a system that underperforms and one that delivers reliable comfort.

Comprehensive assessment

Inspect existing equipment, ductwork, insulation, and electrical systems.
Evaluate indoor air quality needs and occupancy patterns.

2. Accurate system sizing

Perform a Manual J load calculation to determine proper capacity for your home or business.
Consider attic insulation, window orientation, and local microclimate in Santa Clara.

3. Equipment selection

Recommend systems with appropriate SEER/HSPF ratings, matched coils, and manufacturer warranties.
Discuss options: central AC, high-efficiency heat pumps, ductless mini-splits, or hybrid systems.

4. Permit and rebate support

Assist with local permit requirements and documentation for city inspections.
Identify typical local and statewide incentives and utility rebates that may apply to energy-efficient upgrades.

5. Professional installation

Follow manufacturer installation standards and local codes.
Perform proper refrigerant charging, duct sealing, and electrical connections.

6. Testing and commissioning

Validate airflow, static pressure, refrigerant charge, and thermostat calibration.
Provide operational walkthrough and documentation for warranties and rebates.

Repairs, replacements, and when to act

Deciding between repair and replacement depends on system age, repair history, efficiency, and comfort needs:

Typical lifespans: central AC and heat pumps 10 to 15 years, furnaces 15 to 20 years depending on use and maintenance.
Repair when failures are isolated and the system is relatively new, or when repairs significantly extend useful life.
Consider replacement when multiple major components fail, efficiency is low, or you plan a long-term stay and want lower operating costs and better reliability.

Timely action reduces emergency breakdowns during heat waves and prevents indoor air quality degradation during wildfire events.

Indoor air quality and wildfire smoke solutions

Santa Clara residents often face challenges from wildfire smoke and urban pollutants. Practical IAQ improvements include:

High-MERV whole-home filters or retrofit HEPA solutions for superior particulate removal.
ERV/HRV systems to manage ventilation without losing conditioned air.
UV germicidal lights and advanced filtration to reduce biological contaminants.
Localized duct sealing and filtration upgrades to prevent smoke infiltration.These measures, combined with a properly balanced HVAC system, improve health and comfort during poor outdoor air episodes.

Warranty, post-installation support, and maintenance plans

Manufacturer warranties cover equipment defects, while labor warranties protect installation workmanship. Post-installation support should include:

Clear documentation of warranties and maintenance requirements.
Seasonal tune-up plans that include coil cleaning, refrigerant checks, filter changes, and electrical inspections.
Emergency repair procedures and response expectations for unexpected failures.
Assistance with permit sign-offs and rebate paperwork to ensure eligibility for incentives.

COVID-19 safety precautions

Technicians follow enhanced safety protocols appropriate for service visits:

Personal protective equipment and hygiene measures during indoor work.
Tool and vehicle sanitation practices between visits.
Options for contact-minimized estimates and digital documentation delivery.These precautions protect occupants while allowing essential HVAC work to proceed safely.

Practical maintenance tips for Santa Clara homes

Replace or clean filters monthly during heavy use and at least every 3 months otherwise.
Schedule biannual tune-ups: spring for cooling and fall for heating to catch problems before peak seasons.
Keep outdoor units clear of debris and ensure good airflow around condensers.
Upgrade to a programmable or smart thermostat to reduce runtime during unoccupied hours.
Inspect ducts every few years for leaks, gaps, and insulation needs.

Well-executed HVAC services in Santa Clara, CA focus on accurate sizing, quality installation, effective IAQ solutions, and proactive maintenance to ensure comfort, efficiency, and indoor air protection against seasonal hazards like wildfire smoke.

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.
