I have used Ace Hi on several occasion for 3 old, rustic cabins. Yesterday was the most recent: a second opinion on a major drain clog that another plumbing company worked on for 8 hours without resolution short of excavating outside the cabin. Mark came to give a second opinion and within an hour or so he had solved the problem - no excavation. Mark, and another employee from the past, has always been kind, patient, truthful, and offers tips for best maintenance of old systems. It's wonderful to have professionals that I trust. Mark, don't you EVER retire!

Rick is always so prompt and does great quality work! We called on a holiday weekend and he was there in 15 minutes and took care of the problem. We needed them again today, and as usual Rick came over in a very timely manner and gave us all the help we needed. Great company! Service: Heating system maintenance

Rick from Ace Hi came out on Christmas morning to address an issue at our rental house. He was very responsive and took care of two issues so that the tenants could have water on Christmas day. We really appreciated their willingness to get out and take care of people, even on a holiday when I'm sure they would have preferred being at home with family.

Previous A/C and furnace needed to be replaced. Went with Ace-Hi and couldn't be happier. Very responsive and the work was excellent! Had both HVAC and plumbing work done and they were great at both. Would recommend to anyone! Services: Install AC, Install thermostat, Heating system installation

We've had two amazing experiences with Ace Hi. First, our house had a water main leak that Ace Hi was able to fix by boring under our front yard and replacing our main line. This was done incredibly quickly and professionally, and even made sure we had running water in the house throughout the process. Very thoughtful! Second, our kitchen sink suddenly stopped draining and Ace Hi was able to come out within 24 hours of us calling to fix the problem. Zach and Jonas were punctual, professional, cheerful, and thorough, ensuring the job was done properly. Highly recommend!

I am incredibly impressed at the straightforward, prompt, and high quality work that was provided. I called after a leak in our water heater and within 2 hours a technician was at our house. Zach and his partner were incredibly professional, kind and knowledgeable. They took the time to explain everything and make sure we knew what was happening before it happened.

They also took the time to engage with our small children and explain what was happening to them as well. Overall our experience was much better than we could have hoped! We appreciate all of you at Ace Hi and are very thankful!

I highly recommend this company for pretty much anything in or outside the home that deals with plumbing, or HVAC. We had them out giving us an estimate for a few things in our house, but our biggest concern was our 20-year-old air conditioner which they replaced the next day with a much quieter american-made unit that is energy efficient. Nick and the owner Gary were considerate and helpful with their conversations over the phone and email.

Ace Hi Plumbing aced it at our house! They are professional, prompt and knowledgable. Mike explained our options clearly and taught up how to change the filter, turn off the unit, etc. They even put down a protective walkway over the carpet and cleaned up beautifully! enough Ace Hi excels at prompt courteous customer service.
