    Rated highly for: Value, Quality, Punctuality, Responsiveness

    I had water pipe burst in the second story bathroom floor. The leak was significant and wasn't caught for several days as no-one was home. I called Thompson Plumbing in a panic and within a few hours, a technician arrived. My technician was Ignacio V. This dude was awesome. Within minutes, he had a small portion of the ceiling drywall removed and identified the leak. Obviously, he was able to fix the leak.I was extremely satisfied with the quick response. It was my first time calling Thompson and it was a good choice. As stressful as the situation was for me and my wife, Ignacio V. made it as pleasant of an experience as he could. He explained everything he found and how he was going to fix it. Very professional, courteous, etc. etc. When that work was completed, he checked the entire house for any other potential issues that could pop up.Other than Ignacio being the right guy to send out to my house, the price was on point. I expected to be charged a lot more than I was. If I ever need plumbing or HVAC work, especially in an emergency, I will be calling Thompson Plumbing and Heating!Thank you Ignacio!

    Garret showed up on time. We explained to him the problem we were having, and he went right to work. He did get the heater to turn on but there is still a problem as the thermostat was set at 70 and it took all day to reach 68 from 64 degrees. There is still a serious problem. You can hear the heater kick on but in a few seconds is kicks right back off again in @ 10 seconds and you can hear a clicking sound like it want to come back on but does not. So there is still a serious problem with the heating system. The problem was not corrected while Garret was here, He did say he would order parts but still was not sure what was going on? Could be a circuit board, Relay solenoid? He or the company need to come back out here and get this problem resolved.

    Honest, reliable, friendly service with a smile!! Garrett showed up on time. He put on shoe covers to protect my floors. He quickly & efficiently installed my new thermostat and cheerfully gave me a brief tutorial on how to operate it. I could not be more impressed with a company thanks to this young man.! I highly recommend this company.

    Very satisfied with their service. Ty did a great job on our heating unit.
    Albert Rosmino
    Ty from Thompson recently did our semi-annual heater and A/C maintenance. (Heater this time, of course.) We like Ty a lot, and are glad that Thompson sends him each time. We are billed annually for this service, it's a reasonable charge, and we believe it will help lengthen the life of our unit (which was rather expensive to replace, but necessary as the old one had lived out its life.)
    Diane Scholfield
    They were vey polite over the phone. Our technician Ramon was efficient, knowledgeable and very kind. We could tell he really knows his business and was happy to answer all of our questions. I will be calling them again for and heating, plumbing or air issues we have, but hopefully not too soon! 🙂
    Katie McIntyre
    Our bathroom faucet was leaking. The undersink hardware was rusted and deteriorated. The technician explained what was needed and helped us order new faucets and necessary parts. The technician was so patient. We were pleasantly surprised that we received same day service on the day we called. Great plumbing service.

    Ty did a great job on the repair of my furnace. He explained what caused the issue and what was required to fix it. I signed up for the annual maintenance program because I had such a great experience with Ty and Thompson Plumbing & Heating.Ty came back again and was extremely patient with me in his explanation of why the thermostats were operating as they were. I would definitely recommend Ty and Thompson Plumbing and Heating to anyone needing repairs on their furnace.

    9/14/22: Met with Garett, the owner, and asked for his opinion on a new HVAC system for 1901 sq ft single story house. I did not want a low-end model and asked his opinion about the high-end model. I also wanted one where the technology has been around a while and is very reliable. Garett said I would like the model between the low-end and high-end. I purchased the system he recommended. My old A/C was installed in 2003 by this same company and it served me well. Note: Garett said it is better to get a new HVAC system while the old one is still working. Meaning, you will be avoiding lots of undue stress caused when the old A/C goes out.10/17/22 to 10/18/22: Andreas & Mark came out to install the new system. They were very friendly, informative, experienced installers. They paid attention to details and made sure everything was working properly before leaving. (I have an engineering mind and ask many questions) They disassembled the old furnace so it could be removed from the attic (the access to the attic was smaller than the old furnace). The new HVAC system works great. Went through a heat wave and through 45 degrees winter spells already. I am really impressed with the 2-stage system. It is very quiet and energy efficient. Don't even notice when it goes on. AC Pro Energy Star 3 ton 2 stage 16 SEER air conditioning with two stage veriable speed furnace and matching coil system. Furnace model: A80US2V070A12L-04 Air Conditioner model: 4SCU16LS136P-3 Indoor Coil model: PL36H145P44935 Comment: I saw signs of mold in the old Indoor Coil when it was removed and inquired how to prevent that from happening on the new system. Mark said there are a few systems that deals with mold. I then bought the one that their supervisor said was the better one: iWave-R Air Purifier. Mark installed it that same day.11/18/22: At my request, Garett came out to hook up extra features that the Nest thermostat provides, it required more wires going to the thermostat then was provided by the old thermostat. Originally, I was to get a Honeywell thermostat, but they threw in a Nest 3rd gen thermostat. I've been with them 19 years: Thompson Plumbing - Heating - Air Conditioning 4749 Oceanside Blvd Ste J Oceanside, CA 92056

    Ramon was awesome.
    Alek Squires
    Ty was very professional, investigated the AC system, and performed the yearly maintenance. I requested a bid for a new heating and ac unit which he calculated and sent to my email. All in all, a very pleasant experience!
    Joe Miller
    Ty came out and essentially refit the lines on my AC. He was quick, knowledgeable and professional. I would definitely hire him again in the future.

    Installed new gas line to outdoor barbeque. Did an outstanding job and it looks fantastic, couldn't be happier.

    I enjoy having the same technician, Brian, come to the house each time for furnace and A/C tune ups. Brian is very good at his job, is conscientious about his work, is a good employee and represents your company well.

    He is very friendly and efficient.

    After dealing with an unreliable company a few years back, Thompson Plumbing has been a breath of fresh air. Ty, the technician who services my house, is always cheerful,knowledgeable, and offers good advice. Thompson answers the phone with a live person (some companies don't) and will try to help out in emergencies. I like being able to rely on Thompson and Ty.
    Deborah Hawkins
    Great customer service highly recommend Thompson Plumbing Heating & Air Ignasio is a great professional technician!
    Alex Sierra
    We were referred to Thompson Plumbing & Heating by a friend after our water heater went out. We had already decided to go to a tankless system, but talking to Will, the Plumbing Service Manager so helped us make the correct system to install for us after reviewing a number of companies and products. He immediately got someone out to our house to review out needs and give us options. Kel was that plumbing Service Tech and he was fantastic. Once we had decided on a product, it required Thompson to send someone to Orange County to get the correct install kit. Will didn't even hesitate and immediately started driving up there to pick up the needed part.The two plumbers, both Kel and Ignacio were so professional, neat and wonderful to talk to. We loved everything they both did to install our system. Everything makes sense and they went to extra mile to do it right!
    William & Valerie Lee
    Ignacio was terrific, and I’d be glad to deal with him again
    Jerald Davitz
    Kel was professional, courteous, and understanding during a very stressful time! He did a quick and thorough repair and was very communicative. Thanks for the amazing service Kel!

    We've used Thompson for a both HVAC and plumbing over the last few years and service is always outstanding. Technicians are friendly, knowledgeable, professional, and on time. They give fair pricing and have been really helpful in providing solid advice on products and maintenance. I really like that they let us know who the technician is with a photo and contact info in advance of their service appt. We'll continue to use them and highly recommend.

    Overall excellent service. Straight forward on the issue with the drainage system and problems. Got the job down temporarily for now. I will definitely be using Thompson plumbing shortly. Thanks again Kel.
    Kurt Dilgen
    We had a dynamite experience with Thompson Plumbing! They are the most organized, professional, competent, easy-to-work with Team of professionals that I have ever worked with! Our plumbing issues that originally appeared as a "huge potential problem" turned out to be handled by Thompson's crew, Ramon and Ignatio, very easily and quickly. They gave us the best assessment, saving us money and they worked around our crazy schedule as we are a clinic. The price was very fair and most of all, I had no stress working with THIS company, unlike all the others who are barely attentive, unreliable and hard to work with. We give this company 2 thumbs up and recommend them to everyone! Heather of Comprehensive Health Centers, Encinitas CA
    Heather Gervasi
    Great technician, explains the highlights of the service provided in a way I can understand. Three years since the system installation with twice a year check ups and our HVAC system is running perfectly. Thank you!!
    Al Colby
    Ignacio and his team were friendly and took care of the problem with expediency. I had minimal time to have an auxiliary water heater removed to facilitate a roof replacement. The removal and rerouting of pipes was performed quickly and set us up to upgrade the main water heater when there is time to do soThank you.i will definitely use him and the Thompson team again to address future plumbing needs

    We can’t say enough good things about Ty and Thompson. They have always been so helpful and work hard to get us on the schedule as soon as possible when we need them. Ty knows our systems well and is so kind/knowledgeable every time we see him (even when I am in a panic and not so fun to deal with). We highly recommend Ty and Thompson!!

    I had Thompson Plumbing, Heating, and AC out to the house over the winter when our heat would not stay on. I also had two other companies come out for assessments and quotes. One of the companies told us the furnace was working just fine even though we couldn't get the furnace to stay on. We installed The Nest thermostat to get better feedback on the system and learned there was in fact a system error. When Ty from Thompson inspected our unit, he identified it needed replacement or substantial repair and was continually turning itself off as a safety mechanism because the damage was a fire hazard. He not only identified the issue but showed the damage to us and explained why it was unsafe to run. We did not try to run the unit again and decided to replace the furnace and install a new AC unit with Thompson after this encounter.We recently replaced the furnace and installed a new AC unit. Ty from Thompson Plumbing Heating and AC provided oversight for the install and process. He was very personable, thorough, and professional and was a pleasure to work with. Thompson Plumbing, Heating, and A/C was also flexible with scheduling when I had to reschedule the heating and A/C install a few times. Although the install took longer than expected, the staff ensured the work was done right, with and by the right experts, and with high quality work to include a sub-contract electrician to wire the new AC unit. At completion, the install was also thoroughly inspected to ensure functionality, safety, and efficiency when operating the systems. I have used Thompson for my water heater repair and maintenance, furnace inspection and replacement, and an AC install on a home that did not formerly have AC. I am happy with the results of all services and will continue a relationship with this company. Highly recommended.

    Ramon was very responsive and very detailed in explaining what the issue was. At the end of the day he took care of it and we are satisfied customers.

    With our 32 year old furnace showing its age we began looking for the right Plumbing Heating and Air Conditioning firm for assistance.While all companies that were contacted seemed competent and deserving, we felt the entire package of value, quality, professionalism (and yes, price) was with Thompson Plumbing Heating and Air ConditioningOur primary contact was with their quote technician Ty Joao, whose many years of actual installments and recent 4 years with Thompson in this role proved invaluable. His visit to assess our needs was not only helpful and instructive, but it gave us the response from Thompson we were looking for. Ty brought this key quality to his assessment of our needs - that he was there to represent us and the needs of our home back to Thompson for the work to be done. His courtesy, attention and professionalism were all a part of his contribution. After one follow-up meeting to finalize the details of the project we were scheduled for the installation within a week.Our Thompson installation team - Arturo Zamudio and Mark Reed - arrived as scheduled and went right to work. The degree of detail and knowledge required for this process became evident throughout that day. Arturo and Mark worked together like a surgical team for over 3 hours - each handling separate tasks key to the overall installation as they completed the replacement of our furnace linked to our A/C system. It was impressive to watch the process proceed flawlessly from start to finish, and noteworthy that not so much as 10 minutes time seemed to be lost to distractions of any sort through the entire process.Art and Mark continued to display the courtesy knowledge and professionalism that Ty brought to the process, and wrapped up the day with a thorough cleaning of our home, and instruction on operating our new thermostat and furnace.Our thanks to Thompson Plumbing Heating and Air Conditioning Services for providing world class service, professional work and a quality product. We heartily recommend them to all in need of their services.Bill and Sue KehoeOceanside, CA

    Ignacio is super friendly and knowledgeable. He troubleshooted and fixed my kitchen faucet and whole house water filter issues pretty quickly. Thank you!Second review, we went back with Thompson Plumbing again because the first time was great. Ignacio came back out and quickly detected a plumbing leak which was actually creating a lot of water damage in our garage ceiling. He fixed it quickly so we could get the restoration guys in the next day. Quick, efficient and professional work with a friendly face. I definitely recommend

    Will was knowledgeable and very professional. He provided quotes and ensured we understood everything before completing the installation. We will definitely be using Thompson Plumbing for our plumbing needs in the future!
