    Great experience. I had a water line break at 7am in the morning, flooding my front yard and called Thompson Plumbing around 9am. When I told them the situation, they prioritized getting someone to my house ASAP. Thomas & Mark arrived around 9:30am and by 10:30am they had an estimate for me. They told me they could fix the leak but it would be an all day job. I agreed to the work, and midway through the job Thomas told me he thought he could fix the problem at a fraction of the cost that I agreed to. Not everyone is as honest as he is. I couldn’t be happier I called. If I ever need any plumbing work, Thompson Plumbing will be my first call and will definitely request Thomas and Mark.Thanks guys!

    Ty was great. Our furnace was acting up, but it turns out it was just the remote we were using on our Nest. He figured it out quick and was super helpful. I will be using this company moving forward for my ac and heating.

    First Class Company! We used Thompson to install a furnace and air conditioner. They were by far the most reasonable and their customer service is second to none. I would like to give a special shout out to Garrett, the technician who came out to help us. He did a great job, was very knowledgeable and informative, and we look forward to working with him again!
    Nicholas Eppers
    Our downstairs heater stopped working recently. Ty came out and gave an extra effort to fix the stuck gas pressure switch. After he got it to work reliably I asked him to order a new one and install it when it arrives. That happened yesterday and was done quickly. We were very impressed with Ty who is very friendly and has great attitude & work ethic. We highly recommend Thompson H&A.
    David Hempy
    We have had them install a new HVAC system and now a water heater. They are very responsive. We called with a leaky water heater in the morning and had a new one put in the same day.These guys are not pushy, so be sure to ask about upgrades, because they will not push them. I opted for a circulation pump with the new water heater, and man, I love it! Hot water within a second of turning the knob!When we did the heat i asked for an upgraded filter and uv light, so my HVAC system is basically a whole house air purifier. I just set the thermostat to run the fan for 15 minutes an hour and our air is clean and dust free.
    Nick Husby
    I signed up for the HVAC twice yearly maintenance which is a great savings and extremely convenient. As always the service tech was very professional, timely and knowledgeable. I feel confident that my AC will continue to keep us cool as it heats up this summer. I highly recommend Thompson Heating & Air, best products and service.I had never used their Plumbing service until having a hot water heater problem. Once again I am extremely satisfied with the service Thompson Heating & Air provides. They quickly got a tech out to fix my water heater. They’re always polite, professional and knowledgeable.Just had my yearly winter maintenance check on my heater. They changed the filter and checked the temperature and UV light. I’m all set till next year. I really couldn’t be happier having signed up for yearly the yearly maintenance plan. It’s a no brainer…they call to remind you and set an appointment. Once again the tech was timely and professional.I highly recommend this company for any & all your heating, air and plumbing needs.
    Janet Dotson
    Ty represents the company well, not only was he on time he came at the beginning of the 2 hour window each visit. He answered every question I had as well as giving me tips on maintenance. He went above and beyond and was a pleasure to have in my home as he was respectful and tidy. I recommend this company as well as this technician.
    Amanda Peattie
    Worked with field officer Thomas Boscacci when we had two consecutive pipe problems. He was extremely helpful and transparent in highlighting the problems and my options. I've only owned my home for a month, so i appreciate him and the work he did. Thanks Thomas!
    Trenton Tanner
    Great experience-very professional and delivered as quoted.
    Mike Wakefield
    Ignacio was very professional and friendly .He explained in very detail about what my best options would be to fix my water heater.So explained that it would be better to get a new water heater cause my water heater was old and piping and shut off valves were out dated.I decided to get the new water heater and I love it.Ignacio did a fantastic job installing my new water heater and after done with installation Ignacio explained everything about the new water heater.I would strongly recommend Ignacio for all your plumbing needs i will definitely be asking for Ignacio again.
    Jorge Pabloff
    Great guy. Was fast. Knowledgeable and trustworthy tradesman. Would use him again!
    Kurt Roscillo
    We initially called them to install a faucet and look at our sump pump. When Thomas our technician arrived my wife showed him the faucet to be installed. Thomas immediately smelled gas. He tested the air and found the leak. He immediately turned off the gas and had SDG&E come out. All of this took place while I was out of town.The professionalism and dedication that Thomas, Kel and the entire staff at Thompson Plumbing showed is great.Definitely going to use Thompson Plumbing with any other problems that arise.
    Russ Abbott

    Bob McCollough
    Ignacio was great!
    Matt Lorne
    Kel was very responsive and professional, and he was able to perform a non-standard piping replacement to unclog my drain. Pricing was fair, the work was done in a timely manner, cleanup was good, and the fix is solid.
    John Hafer
    Ty our service tech was on time. He found our problem and fixed it within an hour and only charged for our consultation fee. $89.Will definitely use them again

    Ignacio was terrific, and I’d be glad to deal with him again
    Jerald Davitz
    He repaired my garbage disposal by pressing the circuit braker on it. He put in a soap dispenser for the sink. I t was really a problem to take the old one out. It was old. The new one looks good now..
    Joan Madison
    They replace all the water pipes throughout the house. Ignacio was fantastic to work with and explained the entire process very well. I would recommend him and the company for anyone in need of this type of service
    john steele
    Thomas Boscacci was very professional and polite. He showed up on time and never talked down to me about the foolish reason our drain was clogged. I would highly recommend this company to anyone who is looking for any of their services.
    Phillip Sheffield
    SDG&E did a complimentary inspection and reported a gas leak to my backyard (BBQ/fire pit). Ignacio, called before arriving, showed up on time, explained the entire process, and thankfully didn't find a leak! I had SDG&E come back out and verify/sign-off that there was no leak, but it was good to know for certain. More than likely thee was residual gas in the ground near where SDG&E actually repaired a leak on the line going to my backyard. I called Thompson because of my previous experience with them and was not disappointed. Ignacio represented Thompson well and is the reason I will use them in the future for any plumbing, heating or A/C issues I experience. I'm all for supporting local small businesses.

    During Sept. 2021 Thompson's Arturo and Mark replaced old HVAC units with new air conditioner AC-PRO and new AC-PRO two-stage furnace with new Honeywell T6 thermostat. AC testing go well but after 3 hot days from cabinet ceiling where is installed internal part of of new AC water leak down to the floor. Next day during inspection Will determined that excessive amount of condensation has been generated around not correctly insulated planum as source of water leak and Mark installed a new insulation. Not tested yet because meantime outside temp drop and AC stop operation. Instead a new furnace start to works giving a sufficient amount of the heat but to frequently start and stop (every 5-7min) During today inspection Thompson's rep. Ty reprogrammed thermostat from 1F to 2F difference in order to make start/stop less frequent, repaired cabinet floor and Arturo installed five high flow registers (delivered by owner). Overall I am very glad with installation and smooth operation of new system done by Thompson
    Stan Korpala
    This is the second time we have used Thompson Plumbing and they did a phenomenal job both times. Kel and the technicians who were with him were very professional, friendly and explained each job in detail and provided an estimate. The parts we needed for the job were not in stock and Kel called everywhere to find it. The last time proved a little more challenging, however I felt that they went above and beyond. Prices are fair and reasonable. Happy to recommend them to anyone! Thank you Kel, crew and the Thompson company!
    Theresa Allison
    Professional, courteous, prompt, thorough, reasonable.
    Len Coultas
    These guys were great! From providing a quote to installation, everyone involved was professional and respectful.

    Evan Parr
    Thomas the technician was prompt, professional and honest. My wife and I were extremely pleased with how he handled the repair for our garbage disposal. I would highly recommend Thompson for plumbing services and especially the technician Thomas who provided us with outstanding service.
    Michael Example
    I called Thompson, because my ac went out, and I needed someone quick, due to my compromised immune system. They told me they could have someone out, same day within 2 hours from the time I called. Amazing! Ty was the tech, and he was awesome. Explained everything to me, waited while I called my husband to let him know what the problem was, and was able to get us up and running. He does need to come back with a part that he has to order, but at least my ac is working again for now. I’m really impressed by Thompson, and Ty, and would highly recommend them!
    Tammy Wilmarth
    Called Thompson Plumbing for several property management emergencies; immediate same-day response! A team of professionals.
    Cathie McGill
    Ignacio was on time and had an amazing attitude.I enjoyed his hard work and conversation.You should request him if you use this company.Update : after the repair my dishwasher stopped working, I called and left a message during the night and they called me back first thing in the morning and sent Ignacio back to make sure everything was OK. He was just as amazing the second time!
    Ashley Myers
    Made me a same day appointment and was right on time. Ignacio was super nice and professional. Got the job done quickly, answered some questions, and overall had a positive attitude. 100% will use and recommend for all future needs.
    Jordan Mellul
    Our bathtub was not draining, and Thompson Plumbing provided help within a few hours. Kel was able to solve the problem quickly, so my kids can take baths now. Thank you!
    Kelsey Lawson
    I was impressed with the customer service when scheduling the appointment, which I was able to set right away. I received an email confirmation. When the company representative was on his way, I received a call. He communicated what the issue was and noted the repair cost, which seemed very reasonable. He didn't try to hint that I repair/replace other plumbing, whch soooo many of the other company's will shamelessly do. This rep (Kel) took care of the job, contacted me with photos of the items being replaced since the work was done at my rental property and I wasn 't able to be there physically. According to the tenants, he was polite, did the job, explained what had been done and then left. I'd definitely use Thompson Plumbing Heating and Air Conditioning again!
    Lisa Balderston
    I had an issue which at first I didn’t think as critical. They showed up promptly, however before the scheduled appointment. It turned out I needed to address immediately. The scheduled the service and completed in two days. The job was done well and professionally
    Jay MacIsaac
    Had them come and retro-fit the gas line for my stove so that it would be flush to the wall instead of sticking out 2-3inches as it was. Thomas did a great job and installed the new stove and made sure it was level and functioning. I will definitely use these guys again as they are trustworthy and professional.
    Michael Paliotti
    Ty did an excellent job. He worked quickly, effectively and explained everything well.

    Jacob PeBenito
    Garett was on time and professional. He listened to all my questions, put up with my barking dogs, and explained everything in detail. Unfortunately I do not have the required attic space for the whole house fan I was interested in, but Garett informed me of several other options I could pursue.
    William Masten
    Ty performed a diagnostic service.
    Max Hoynacki
    Kel was thoughtful and knowledgeable. He installed a new faucet that is attractive and well made. He offered to see if he could find a replacement filter for the existing water system we have. We have used Thompson Plumbing for several plumbing repairs. I highly recommend them.

    From bid to finish, excellent service. Finished in 3 days installing 6 units (3 heaters and 3 a/c) as well as all new ducting. Suggested very good design changes from original system. Kept everything clean during job, and could not tell they had been here (except for new quiet equipment) after they left. Recommend highly.
