Licensed to Chill

The line set, flares, pressure test, evacuation and commissioning decide whether a mini-split delivers quiet, efficient comfort for years. Jon documents the numbers instead of guessing. Mini-split line sets use flare connections tightened to the specified torque, without brazing. Single heads are Jon’s focus; he will explain the best layout for your home.

Jay Michael Hughes

Jon Hughes is the best fellow for any type of HVAC Mini Split Service. If Jon installs your Mini Split, you will have many years of trouble free service. Very honest person.

Grants Pass Homeowner

Jon is the best HVAC guy in the world... cares about doing the best job possible, at an affordable price. He has the best, state-of-the-art HVAC tools. Mini splits installed by Jon will last longer because he is meticulous about the install, and then following up with a pressure test and vacuum decay test before charging the system. His vacuum procedure, tools, and final test are light years ahead of other HVAC techs.

Mark Tilles

Jon is one of those trade experts that not only knows what he's doing, he's willing to share that knowledge freely to make sure others are educated, comfortable with the equipment, and always happy to help a DIYer learn to be self sufficient.

John Hobson — Local Guide

The deck looks amazing! I can't thank you enough. It's so hard for my 90 yr. old mom to trust anybody... especially after being married to a perfectionist carpenter for 65 years! She really liked you and your kindness reduced her stress immensely. Please know that in these troubling times you have brought peace and joy to this family. We will always call you first from now on!
