Heat Pump Service in Atherton, CA

Keeping your home comfortable year round in Atherton, CA means choosing the right heating and cooling system and maintaining it properly. A heat pump delivers efficient heating in mild winters and reliable cooling during occasional hot spells. This page explains comprehensive heat pump service in Atherton, CA — installation, routine maintenance, repairs, diagnostics, emergency response, pricing and financing structures, licensing and warranty considerations, and guidance on scheduling service and obtaining rebates or inspections.

Why a heat pump makes sense in Atherton homes

Atherton enjoys mild winters and warm to hot summers during inland heat events. Heat pumps perform very efficiently in this climate, providing energy savings compared with older electric resistance or inefficient HVAC systems. Because California energy standards and local utility incentives favor high-efficiency equipment, selecting and maintaining the right heat pump is an important decision for long-term comfort, lower energy bills, and regulatory compliance.

Common heat pump issues in Atherton

Understanding common problems helps you choose the right service and recognize urgency.

  • Poor heating or cooling output - often due to low refrigerant, airflow restriction, or incorrect thermostat settings.
  • Short cycling or frequent on-off cycles - caused by improper sizing, faulty controls, or refrigerant issues.
  • Frozen outdoor coil or defrost failures - common in systems with defrost control problems or restricted airflow.
  • Noisy operation - worn bearings, loose panels, or failing compressors can create vibration and noise.
  • Electrical faults - failed capacitors, contactors, or breaker trips can prevent system starts.
  • Ductwork and airflow problems - leaks, poor insulation, or blocked returns reduce efficiency and comfort.
  • Aging components and refrigerant leaks - older units may leak refrigerant, reducing capacity and efficiency.

Types of heat pump services offered

Services are tailored to the issue and homeowner goals, from emergency repairs to full replacement.

  • Installation and replacement: sizing and equipment selection, ductwork evaluation and modifications, electrical and permit coordination, system commissioning and performance testing.
  • Routine maintenance and tune-ups: seasonal inspections, filter and coil cleaning, refrigerant checks, electrical tightening, and operational testing.
  • Diagnostics and performance testing: refrigerant pressure checks, airflow measurements, thermostat calibration, and compressor health evaluation.
  • Repairs and component replacement: leak repair, compressor or reversing valve replacement, control board and sensor replacement, and fan motor service.
  • Emergency response: after-hours diagnostics, temporarily safe operation guidance, and prioritized repairs during extreme weather.
  • Energy audits and retrofit work: efficiency upgrades, zoning solutions, and controls integration to improve comfort and reduce operating cost.

Diagnostic and service process explained

A clear, methodical process ensures reliable outcomes.

  1. Initial assessment: technician collects symptoms, system age, and recent performance history and inspects outdoor and indoor units.
  2. System diagnostics: measured refrigerant pressures, amp draw on compressors and fans, temperature split across coil, and airflow readings. Duct leakage and thermostat communication tested as needed.
  3. Findings and options: clear explanation of root cause, repair vs replacement implications, expected benefits, and any permitting requirements for larger projects.
  4. Repair or installation: component-level repairs include verified leak repair and recharge, electrical component replacement, or full system swap with load calculation and proper refrigerant charging.
  5. Commissioning and verification: final testing, thermostat programming, and documentation of serial numbers and performance metrics.

Repair and solution considerations

When deciding between repair and replacement in Atherton, consider system age, refrigerant type, and efficiency.

  • Repair when failures are isolated (electrical component, compressor short life remaining) and the unit is relatively new.
  • Replace if the unit is older than 10 to 15 years, uses obsolete refrigerant, or has repeated compressor or refrigerant leak problems. A modern heat pump often delivers higher SEER/HSPF ratings and better defrost control for local conditions.
  • Ductwork improvements often amplify benefits of a new system by reducing losses and improving comfort distribution.

Pricing and financing options

Homeowners commonly see a range of pricing structures. Typical formats include:

  • Diagnostic fee plus itemized repair estimate: a fixed diagnostic charge followed by a transparent parts and labor quote.
  • Flat-rate installations: all-inclusive pricing that covers equipment, standard materials, basic duct modifications, startup, and permitting where required.
  • Tiered maintenance plans: annual or semiannual maintenance contracts that include regular tune-ups, priority scheduling, and discounted parts.
  • Financing options: low-interest financing, monthly payment plans, and energy loan programs that convert an upfront investment into manageable payments while preserving cash flow.
  • Rebate-ready documentation: quotes and invoices prepared to satisfy rebate program documentation requirements, which can affect net cost.

Licensing, permitting, and warranties

Regulatory compliance and warranties protect your investment.

  • Licensed technicians: ensure work is performed by appropriately licensed HVAC and electrical professionals who are familiar with California codes and local Atherton permit processes.
  • Permits and inspections: major installations typically require permits and municipal inspection to verify safe electrical connection, refrigerant handling, and compliance with Title 24 energy standards.
  • Manufacturer and labor warranties: new equipment carries manufacturer warranty on major components, and reputable service providers often include a labor warranty for repairs and installations. Retain invoices, model and serial numbers, and permit documentation to support claims.

Scheduling, rebates, and inspection guidance

Preparing ahead makes scheduling smoother and increases the chance of qualifying for incentives.

  • What to have when scheduling: system brand and model, approximate age, description of symptoms, and availability of past service records or permits.
  • Rebate and incentive basics: many state and utility programs require ENERGY STAR or specified efficiency ratings, proof of purchase and installation date, and sometimes pre-approval or a post-installation inspection. Keep equipment serial numbers, permits, and itemized invoices to submit with rebate applications.
  • Home energy inspections: a whole-house energy inspection or duct leakage test can be requested to document baseline performance and support efficiency claims for rebate applications.

Maintenance tips to extend life and efficiency

Routine care improves comfort and reduces emergency repairs.

  • Replace or clean filters monthly to quarterly depending on use and filter type.
  • Keep at least 2 feet of clearance around outdoor units and trim vegetation seasonally.
  • Schedule an annual tune-up that includes refrigerant check, electrical safety inspection, and airflow measurement.
  • Check thermostat batteries and settings; consider a programmable or smart thermostat for better zone control.
  • Address unusual noises, odors, or decreased performance promptly to avoid secondary damage.

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.

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.
