Gas Furnace / Forced Air Heating System - Repair
$129
​Loos & Sons HVAC did a stellar job diagnosing the issue with our system; the technician was incredibly knowledgeable and quickly pinpointed the root cause. We especially appreciated that they took the time to clearly educate us on the problem and walk us through all the available solutions. This commitment to transparent service and customer empowerment makes them our new go-to company, and we highly recommend them.

John does great work! Nothing was open and he got on FaceTime with me helping to figure out the problem with our heat pump when no one else was available. He made sure everything was safe for our family and finished the job I started on my own. He was very understanding and let me know all my options without any pressure. Highly recommend!

John drove up to Grand County to look at several of homes in our neighborhood for different options for AC. He took the time that was needed in each home to make sure all information was given and all questions answered.
