Heating Service in Palo Alto, CA

Keeping your home comfortable and safe through Palo Alto’s cool coastal evenings and occasional winter chill requires reliable, expert heating care. Our comprehensive heating service in Palo Alto, CA covers inspection, repair, maintenance, replacement, and emergency support for furnaces, heat pumps, and ductless systems. This page explains what to expect, common heating problems in Palo Alto homes, the diagnostic and repair process, technician credentials, guarantees and warranties, transparent pricing practices, COVID-19 safety measures, and the typical steps to request a quote or schedule service.

Why professional heating service matters in Palo Alto

Palo Alto’s climate is mild but can have sustained cool nights and damp conditions that place demand on heating systems. Many local homes combine older gas furnaces with newer heat pump technology, and the trend toward electrification means more homeowners upgrade to high-efficiency heat pumps or ductless mini-splits. Proper heating service improves comfort, reduces energy use, extends equipment life, and ensures safety—especially important for gas appliances and homes with tightly sealed construction.

Common heating issues in Palo Alto

Understanding frequent problems helps you spot issues early and choose the right service:

Uneven heating or cold rooms, often due to improper zoning, airflow restrictions, or undersized equipment
Weak airflow from vents caused by clogged filters, blocked ducts, or failing blower motors
Short cycling or frequent on/off cycles, commonly from thermostat problems, dirty heat exchangers, or refrigerant imbalance in heat pumps
Pilot or ignition failure in older gas furnaces
Strange noises (banging, rattling, squealing) signaling mechanical wear or loose components
Rising energy bills from failing components, poor maintenance, or inefficient older systems
Heat pump performance drop in damp or foggy conditions caused by coil icing, refrigerant loss, or compressor wear

Replace or clean filters every 1–3 months depending on occupancy and indoor air quality needs
Keep vents and returns unobstructed and periodically inspect accessible ducts for leaks or insulation issues
Install and test carbon monoxide detectors if you have any gas-burning appliances; replace detectors per manufacturer guidance
Consider upgrading to a high-efficiency heat pump or ductless system when your equipment is over 10–12 years old to reduce energy use and improve comfort

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.
