Best High Efficiency Furnace in Kansas City MO

What my husband understood from the tech (Jessica) who was here said sounded like there was an an installation problem from 2 years ago. Faulty valve stems. I'm tried of having to pay so much for my air conditioner every 2 years. You were supposed to fix that when we did the whole system (from AC outside to Furnace inside, and insulation in the attic, etc, for $12000). If that was the case (installation of faulty valve stems) we shouldn't have had to pay $300 for all the Freon that leaked out from those faulty valve stems. Yet we did. $500 you charged us. And we'll have to pay for labor when you replace them. That's really not fair. I liked R-Mech and was willing to recommend them. Now I'm not so sure.R-Mech called us back and has gone out of their way to make this situation better for us. I love good customer service and I would gladly recommend R-Mech to anyone. And let me be clear, we were not criticizing Jessica or her work here. She was competent and courteous and we have no complaints about her visit.
