You charged me $842 for a Honeywell Aquastat but installed a Hydrolevel Hydrostat 3250-PLUS which I can buy online for $188! HYD-ZON31 Taco Zone Valve...you charged me $745.56. The valve is $134 on Amazon. How much labor does it take? You sent two guys that were here a total of less than 3 hours to do all this work.....$3609.80!!
