Excellent Service

Christopher Martinez took numerous photos inside and out of the combination unit located on the roof that he shared with me, including meter readings, and carefully answered all of my questions and explained what each reading indicated when he was finished with the job. He was very meticulous and methodical in checking out the entire system, including the electronic filter and the handler, and also in assuring every part of the unit was thoroughly cleaned. I was very impressed with his knowledge and his friendly and polite manner.

Couldn't have been better

Thompson was recommended by a friend who had used them. I am so glad she suggested them. The service, professionalism, timeliness and products are all top-notch as were the techs on the jobsite. We highly recommend them. Their pricing was WONDERFUL when we compared it to their competitors!

Awesome Experience

No one loves to spend money on AC issues. Dylan made the process as painless as possible. Was great with my kitty also. Nice to hear he is a Marine vet. Happy to be a new member of the Thompson family. Will recommend to friends and co-workers in our local area. Very thankful him and Trevor were able to tag team the ducting work we were also getting done. There was no need for double work. I appreciate the thought that was put into everything as he saved us time and money by preventing redundancy.

Thompson Plumbing, Heating & Air Conditioning came out to evaluate and diagnose 4 year old Rinnai tankless water heater with an error code 17. Performed a hard reset on unit to remove code and to regain hot water to residence. Called technical support and it’s recommended to remove, inspect and clean gas valve assembly. This will prevent error code 17 from reoccurring. In addition, a trap will need to be added to condensate line to prevent condensate from backing up and entering water heater. Justin would like to have yearly descale service performed at the same time of gas valve repair.

Thompson, plumbing, heating, and air-conditioning came out to evaluate a mainline stoppage, after running water through fixtures did confirm clients concern mainline will have to be snaked to clear stoppage. Provided Lorraine with an estimate, she approved and work began and completed same day. Stoppage was at cast-iron pipe where it goes underground unsure if that is client, responsibility or mobile home park, she may want to ask Office manager of Mobile Park to verify. Ran water through fixtures when snaking and was completed, everything is draining as designed no more stoppage present. Thank you for calling, and choosing Thompson Plumber heating and air conditioning
