Ty was very thorough and shared his knowledge as he went through the service.
Thank you, Paul. We're glad Ty was thorough and shared his knowledge during the service. We appreciate you taking the time to leave this review. We look forward to serving you again.
Ricky did a great job checking out my A/C. Very knowledgeable and found the problem right away. Troubleshooted my A/C and only charged a nominal fee. I will definitely consider Thompson for any A/C or heating issues in the future.
Thank you, Stephen, for the kind review. We’re glad Ricky could quickly diagnose and troubleshoot your A/C and that you found the service and fee fair. We appreciate you considering Thompson for future heating and cooling needs. We look forward to serving you again.
Ricky was awesome. We had someone out previously who insisted they couldn’t access or service our unit. Ricky had no issues and made a big difference. Go-to support moving forward!
Thanks so much for the great review, Evan. We're thrilled Ricky was able to access and service your unit where others couldn't and that he made a big difference. We'll pass your praise along to him. We look forward to being your go-to support moving forward.
Clean, fast and a good price!
Thank you, C! We're thrilled you found our place clean, fast, and well priced. We appreciate your feedback and look forward to serving you again.
The project involved replacing ducting for our HVAC system in a very tight crawl space under the house. The quality of work performed was clearly evident. Thanks to Mark Thompson for his efforts.
Thank you Steve. Replacing the duct work was a challenge but Mark stepped up to the plate.
Height of a summer heat wave, and they got me an appointment by the next day. Proceeded to get a tech out day of ( confirmed with me of course!) and the tech (Ricky R.) was incredibly knowledgeably and answered all of my 1000 questions. Thanks a bunch!
Thanks for the kind words, Kevin — we’re thrilled we could get you in quickly during that heat wave. I’ll be sure to pass your compliments along to Ricky R.; he’ll be glad to hear you appreciated his help and patience with all your questions. We’re here whenever you need us.
Jared from Thompson came out the same day our AC was having issues! I had originally scheduled an appointment with another company and I didn’t trust the outcome of the issues so I called Thompson to come and they gave me the truth about our Ac along with the repairs needed. Thank you for your honesty and saving the day!!! Highly recommend
Thank you, Lindsey! We’re so glad Jared and our team could come out the same day and provide honest, clear information and the repairs your AC needed. We appreciate your trust and recommendation. If you need anything in the future, we’re here to help.
