    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.

    Ty showed up on time, performed the service, and kept things neat and clean.
    Jerald Davitz
    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.

    Had a problem without ac ducts and wanted to have someone take a look. Ty came on time and was able to provide as much assistance as he could on the matter. Didn’t waste anytime. Highly recommend.
    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
    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.
    Janet Dotson
    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.

    Exceeded expectations in all respects.
    Trice Mott
    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.
    Ed Walton
    Garrett is great. On time...kept me informed. Very knowledgeable.
    Vic Wintriss
    We had a furnace from the early 1980's. We wanted to add AC but because of the age of the furnace, we needed to replace the entire system; ducts, furnace, thermostat, AC unit (new), and all.The crew showed up on time, were respectful, cleaned up after themselves and explained everything as the job progressed. It only took two and one half days from start to finish. We received top end 0 high grade equipment, a professional installation, and good service for a reasonable price. We're glad we went with Thompson!
    Bill Noonan
    They were courteous, prompt and professional. I was very happy with their service and courtesy.
    Phyllis Russell
    We recently added AC to our home. Thompson honored a quote from September. They were communicative through the entire process and Ty and Ted were great - keeping us updated every step of the way! Definitely recommend!
    Michelle Huang
    Excellent professional service
    Tim Buskirk
    My sister, who is fighting stage 4 breast cancer and her husband have been living in my mom's mobile home since she passed in May, 2020. They are struggling, like all of us and don't have very much money. The family became aware that their furnace stopped coming on and I called Thompson Plumbing and Heating to send a tech out. The tech came out the very next day and said that the pump was stuck and it may need to be replaced. He got the furnace working that day but the very next day it stopped again. The cold affects my sister very much and she and her husband were huddling around a space heater to keep warm. I got an estimate for the cost of the part and it was astronomical. There was no way my sister or the family could easily spare $562. I called Thompson Plumbing and asked if there was any other way we could get the furnace working, maybe a rebuilt part or a used furnace or part. They said "no" because of the liability. I thanked them and hung up. Before I could call anyone in the family, Thompson Plumbing called back and the girl said the owner was informed of our situation and he was going to provide my sister with the part and labor to install it at no charge. Merry Christmas! This was the most unselfish and caring gesture I have ever seen. May God Bless the owner and good people at Thompson Plumbing Heating and Air Conditioning...you have made my sister's Christmas so much brighter and definitely warmer.

    Michael M. was on time and replaced our water heater today. Thank you!
    Suzanne Maurice
    Water heater technology reset. Unclogged a sink. Installed a bathroom faucet.
    John Novak
    I was very pleased. Everyone I dealt with was friendly and also professional. I am very happy with my new furnace and feel as if I paid a very fair price. I highly recommend Thompson!
    Timothy Zuverink
    Same day service and even texted that he could come early! Installed new toilet correctly and fast! Good price too, I will use these guys again! 😊
    Debra
    Very happy with service. Showed up on time, with booties and a mask! Explained situation and options. Very patient since my husband and I were driving him crazy with questions and interrupting him constantly.
    Jean Keane
    I had an angle stop leaking that was frozen and impossible (for me) to remove. Thompson sent a technician out and replaced the valve ASAP. Their technician worked efficiently and in a professional manner. Prices were fair too!!
    Benjamin Wilson
    Mike installed a shower cartridge/valve.He arrived on time and did a perfect repair.Very satisfied with the staff at Thompson Plumbing.
    deanna GAUDINEER
    Thompson was the most responsive of the companies I contacted for bidding. Their installers left our place clean and were respectful, wearing masks and booties while indoors. I heard no bad language from them and they listened to all of our concerns. There were a few technical difficulties encountered during installation, but Thompson completed the job for the quoted price. I am not sure how they compare on price because the other two companies took so long to bid that I just went with Thompson. Responsiveness is important to me because it makes me confident that there will be good service and repair times on my units after they are installed. I am glad I bought their best system; it is so efficient and so quiet.
    mike sutherland
    Thompson Plumbing Heating and Air Conditioning were just what we needed for AC purchase and install. Did my research, obtained 4 great quotes for service but so glad I chose Thompson. From the initial quote through to the install Garett and installers Tyler and Ryan were a step above, highly professional, open and honest and they did a great job to high specs, very happy thanks guys.
    Dom Zimmerman
    Overall a great experience! Garett was a pro, he was able to figure out the issue with our central cooling (and heating) quickly. Due to COVID, turnaround on parts was maybe a bit slower than usual, but he explained the situation up front during the inspection. Only a few days later, he was back, the board in our furnace was replaced, and our A/C was running again! He was even early for the follow-up, after a call to make sure I was home.Communication with the office staff was great, and between calls, texts, and emails, I had no concerns about missing a message (or an appointment).Highly recommended for North County HVAC service.
    Nikolaus Ehm
    Garrett was very personable, gracious and best of all, supremely knowledgeable. Definitely looking forward to working with him again in the near future. Thank you for sending him so quickly, Thompson’s!
    Ramm Phillips
    Thompson Plumbing was very responsive and punctual. The plumber, Mike, did a great job discussing the work and his recommendations prior to starting. I would highly recommend this company.
    Kenia Rosete
    Thompson installed my heating and air conditioning two years ago. Recently I was having an issue with my AC unit and they were able to come out the next day. They evaluated the problem, ordered the part and came back the following day. It was all covered under the warranty. They are always a pleasure to work with and this is the second house I have had them install AC.
    Jay Delcamp
    Thompson diagnosed the issue and fortunately had a suitable replacement. They installed, programmed and gave instruction on the thermostat. Very pleased with their service.
    Beny T
    AC was not cooling effectively late on a Friday during a heat wave. I left a message on Friday evening not expecting to hear back until Monday, anticipating that we’d literally have to sweat it out until I could get an appointment. Instead, I got a phone call the next morning. Thompson Heating & Air was able to get a technician to my home on Saturday! Yippee! The issue was addressed and we were able to stay cool. Couldn’t be happier with the service & expertise!
    Ruby MacPherson
    Great and responsive customer service. The technician was able to come out that day and fix our AC. Highly recommend this company
    David Chaffee
    Great products and installation.
    Shelley Grossman
    Garett is very knowledgeable and very professional. Great company to deal with. Came in less than 30min and fixed my A/C problem
    Raul Flores
    I love Thompson and I've used them a few times for different reasons over the years. They're always prompt and professional and have the nicest technicians that do quality work.
    Julie Anderson
    Ty and Ryan did such a great job!! They installed new AC in a condo that never had it to begin with, so they had to do some retrofitting to make it work. They knew what they were doing and were very pleasant to work with. Will definitely use Thompson again!
    Lisa Moon
    Thompson plumbing was quick and on time. The plumber that came in seemed very knowledgeable on what he was doing. The only thing I do have to comment on though is that the plumber who came in wasn’t wearing a mask. He didn’t even ask if he could come into our home without a mask. I have a newborn so it was a bit concerning. I didn’t say anything because he had already worked inside by the time I noticed. He also put his personal stuff on my newborn’s stroller seat that was sitting in the hallway, which was a bit odd. Aside from that, he was fine.
    Grace Belna
    Mario came out and did the summer service. I was thoroughly impressed . He explained everything and made easy to understand what was being done and why. Thank you again Last year, it was Ryan and he was awesome and advised me on how to maintain my air scrubber. Great techs at Thompson Heating and Air
    Arun Prabhakaran
    Had an issue with an air scrubber. Thompson was straightforward in pricing to fix it. The tech was awesome. He found the issue and spent a good bit of time to resolve it. He found a great option for me. I am very happy. From scheduling to the tech, it was an awesome experience. Thank you.Ryan was very knowledgeable and advised me how to maintain my air scrubber . Awesome tech.
    Arun Prabhakaran
    I am very happy with the quality of service and professionalism I experienced with Thompson Pluming Heating and AC. I would highly recommend them. It's blazing hot outside and I am just chilling inside! I am ready for summer!!
    Linda Kirkpatrick
    Andrew put in a lot of effort to unclog our patio drain, but after two hours of hard work, he could not get it cleared of roots. Because the drain was still clogged, Sarah at Thompson's gave us a very fair price reduction. We would definitely contact Tompson Plumbing in the future, and recommend them highly to our friends and neighbors.
    Scott Engrav
    Andrew came out promptly and took care of a leak that originated behind a wall. He was professional and helpful and I would recommend this company to a friend.
    Alex Perelson
    We are so happy we found this company on Yelp! From getting the estimate to the day of the install of the AC everyone was on time, super polite and professional, and throughly explained everything. A huge thank you to Garrett and Tyler for such great work!
    Melissa Lane
    We had a blocked MBR shower drain and food waste disposer at kitchen sink. I got Thompson Plumbing Heating from a good friend. Andrew Stewart came out to work the problems and was outstanding. The food waste problem turned out to be just a loose fitting and Andrew tightened it without charge. The shower drain problem was rodded out at length and now flows well. We are proud to have the fortune of having Thompson and Andrew on the job.
    Richard Benson
    Andrew was great. Thanks for the wonderful service.
    Rick Prescott
    Honest evaluation of the problem with our air conditioner, fair pricing and future recommendations for upkeep

    cool guys, easy to work with , I will share this with all Midas locations in San Diego . Thank you.
