I have had a decent experience with Qualtech Heating & Cooling. Recently, they installed a new furnace. Their technicians are knowledgeable, and use good products. They installed a new furnace, and the job turned out well.
They always arrive on time, and clean after they're finished. The only issue I run into with Qualtech is the final price. I'm quoted one price, but it usually ends up being more expensive.
