After charging us all kind misc expense, 2 times repair, cost over $2000, nothing got done, actually before the air balance system was sometime working, now after they repair it, it got worst. the exhaust system totally stop producing warm air. I dont mind to pay for what ever cost to repair it, but don't fix it half way, then told me you fix it.

I attend training here. They are always very friendly and professional. The badge photos are taken under some bad lighting so I hide my badge/photo when I can.
