    Duane repaired our ac unit on 7/11/2025. His repair followed his initial service where he identified problems and ordered the needed parts to repair our ac unit. The parts arrived on a Thursday afternoon and he was at our house early Friday morning installing the new parts. Duane is an outstanding service tech from Donnelly and he is knowledgeable and efficient. I give Duane 5 stars. Vince Sobocinski

    Five stars for Joe Albert, who oversaw the installation of a new HVAC system in my home a few months ago. PLUS, he recommended a different propane supplier than my current one, with an expected annual savings of about $2,000!! Thank you, Joe!!

    09-JUL-2025 Oscar Sosa Salinas, our service tech, was dispatched for our shifting toilet that leaked water onto our bathroom floor as well as down into our basement. Bottom line, we decided to to have the entire toilet removed and a new one installed. Oscar gave us options to go buy one ourselves (1 yr store warranty) and he'd install it - or, he'd buy one through their supplier with a 3 or warranty and he'd install it. For us, that 2nd choice was well worth the expenditure. Oscar was very professional in his approach to our needs. Thanks so much, Oscar!

    Jason did an excellent job of repairing my split AC units. I like that he was the same person that I had met when he came out to do the general servicing of my AC unit. I felt he was very thorough and took his time in getting everything completed and assuring that everything was working correctly
