"The technicians are so nice and helpful, professional, and punctual. They've maintained my hvac for the three years I've lived in this house and all runs smoothly."

"The person who handled my call was friendly and professional. She told me a technician would be at my house in 4 hours and called me when he was on his way. The technician was outstanding, on time, professional, friendly, and quickly diagnosed and fixed the problem...best of all, he didn't try to sell parts/service that I didn't need! Best experience with an HVAC company I've ever had."

"A-ok! Dunn OneHour HVAC is always top notch!"

"Yearly check up on my HVAC system. Found n fixed a problem. Applied senior discount. Prompt n courteous."

"They were professional from the phone call to the installation. He had everything he needed to replace the hot water heater and proceeded. I would definitely recommend Hosack Plumbing."

"Seems I was spending a ridiculous amount of money on electricity because my central unit was not operating correctly. I now have flowing cold air."

"The owner was very knowledgable and courteous and really took the time to explain what was wrong and didn't charge a hefty fee for looking at the air conditioner and fixing it. I will definitely use his services again."

"Had new hvac, furnace, and hwh installed. Furnace had a couple of air leaks between a coil and furnace which I fixed myself. Hvac was spot on. Hwh failed first inspection, but was corrected in same day. For the premium price paid, these issues should not happen. Quality 4.5 because of these issues, same goes for value. Customer service is very good. They are very professional, work looks very good, clean worksite afterwards. I would recommend, but don't think about negotiating price with them. Their labor is very high."

"Job well done.  Our Sub-Zero refrigerator was showing error messages and we called All American after reading reviews.  We called on the weekend before Christmas and had an appointment on Tuesday.  Jon - the tech - was great.  He quickly ascertained the problem and explained it - coils in the back were leaking.  Since parts had to be ordered, we had to wait the next week for the repair.  We were nervous about getting through the Holiday, but Jon said he thought we would be fine.  Thankfully, we made it through the Holiday and Jon returned to perform the repair.  He was on time and once again took the time to explain things as needed.  The process couldn't have gone smoother and we would recommend again.
