“Had an issue with my condensation line being clogged up which caused the drain pan to overflow & start leaking from my kitchen ceiling. I immediately called One Hour because I am a current customer member & even though this was after normal business hours, they were able to send a tech over once he was done at his current location. Mr. Vargas called once he was on his way & did a fantastic job! I asked if he would allow me to watch what he did & ask questions & he was very accommodating, thorough & explained exactly what he was doing & why. I highly recommend these guys as this was not my first emergency disaster that they rescued me from! Always very helpful & professional!”

“Francisco Vargas is hands-down the best HVAC tech I’ve ever had the pleasure of working with. He came out for a follow-up and spent over an hour carefully diagnosing and fixing my AC unit until everything was running perfectly. He didn’t rush, didn’t cut corners—he took his time, explained what was going on, and made sure I was good to go before he left. More than just being professional, Francisco is a genuinely great guy—chill, super friendly, down-to-earth, and kind. The kind of guy you’d grab a beer with after work. I can’t imagine calling anyone else out here after this experience. One Hour is lucky to have him, and you’re lucky if he’s the one who shows up at your door.”

“Mat was amazing, honest and very professional. He took the time to answer all my questions, explained everything to me. He was extremely knowledgeable in his field of work. He was able to explain the difference in the products they have and how they work. I highly recommend him. He is the reason we will be using this company. Thank you for a great job!”
