Earned my trust
This is my third year with QD. I also had a rental property that was being serviced by another HVAC company. The other company wanted $2300 to repair a unit that was already under warranty. It was only four years old. QD came out and after careful analysis and testing determined it nearly needed a different type of filter with a few minor adjustments to heat properly. My total bill was $99. I have since switched all my business to QD.
