Common Heat Pump Water Heater Issues in Redwood City Homes

Heat pump water heaters are prized for their energy efficiency and environmentally friendly operation. However, like all mechanical systems, they can encounter problems that affect performance or cause total failure. In Redwood City’s temperate coastal climate, these issues can sometimes be complicated by humidity and fluctuating temperatures, making timely repairs all the more critical.

Typical issues we service include:

No Hot Water or Insufficient Hot Water: This is often caused by thermostat malfunctions, compressor failure, or refrigerant leaks.
Water Leaks Around the Unit: Leaks may arise due to cracked tanks, loose fittings, or drainage problems with the condensate pump.
Compressor and Refrigerant Troubles: Compressor breakdowns or refrigerant leaks reduce heating efficiency and can cause costly damage if neglected.
Electrical Faults: Wiring problems, faulty sensors, or failed control boards can interrupt the operation of the water heater.
Unusual Noises or Frequent Cycling: These symptoms often signal internal component wear or refrigerant issues.
Error Codes and System Warnings: Modern heat pump water heaters self-diagnose, displaying error codes that guide troubleshooting.

Diagnostic and Troubleshooting Procedures for Heat Pump Water Heater Repair

At Plum HVAC, our Redwood City technicians utilize a systematic diagnostic process to accurately identify the root cause of your heat pump water heater’s failure. This starts with a thorough visual inspection and history inquiry— pinpointing when problems began and under what conditions.

We then proceed to:

Test electrical components with specialized tools to verify voltages and continuity.
Inspect the compressor and refrigerant system using gauges to detect leaks or pressure anomalies.
Evaluate thermostat and temperature sensors for proper calibration.
Analyze drain system functionality, checking for clogs or pump failures.
Assess error codes via onboard diagnostic displays to guide repair prioritization.

Our comprehensive diagnostics enable swift, precise repair recommendations that save you time and unnecessary parts replacement.

Typical Parts Replaced During Repairs

Heat pump water heaters consist of several intricate components, any of which may require repair or replacement when faulty. Common replacement parts in Redwood City homes include:

Compressors and compressor relay switches
Refrigerant lines and seals
Thermostats and temperature sensors
Electronic control boards and circuit panels
Drain pumps and condensate lines
Heating elements (in hybrid units) and pressure relief valves
Expansion tanks and temperature/pressure sensors

Each part replacement follows best industry practices and manufacturer-specific guidelines to preserve system integrity and warranty compliance.

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.

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.
