"Elsy ( I believe she was the plumber from your company via Angi) arrived as scheduled, on Saturday, 09/28/2024. She attempted to repair my garbage disposal unit but was unable to do so as the unit's wiring was worn out. I advised the unit is 40 yrs old. She recommended to purchase a new one. We made a trip together to the local Home Depot store and I purchased the same brand s she recommended. She installed it in record time (within the 2.5 hrs) and completed the job. She also cleaned the work space and carried the old one to my recycling bin. Very satisfied with her work. Also, I want to know if I will receive a billing statement for my records? Thank you for your time & assistance."

"My AC stopped working last November, and since then i had 4 contractors i called to fix it, i was turned down by everyone. i called Tyndall and peter came out and talked about it with me, actually troubleshot it, and 2 days later had parts and fixed it. i would give them 6 stars if i could. im so glad to have my ac running again. my recommendation, if you want something done, call Tyndall, because the rest of the contractors seem to just say its not fixable and leave without even looking at it. these guys were the first people that listened, then looked at the unit before declining service, and then actually fixed it. 10/10 great job and thank you."
