I really think this was worth my $85.00. Fritz arrived on time and went right to work. He brought a long ladder which he needed to get up on my roof. He shortened my dryer hose behind the unit so it would dry better with less turns in it. When you think it could cause a house fire in which you could lose everything you've worked for and possible family members this is a cheap price. I'll gladly have him come back every year from now on.
