Would never use them again due to last service performed by there service tech Matt. Ruined a perfectly good Furnace when he bit off more than what his capabilities would allow when he performed his service. Furnace always has to be kick started by flicking breaker off and on after power outage now and never did that before he arrived. We paid 11,000.00 in 2009 for a Lennox heat pump and high efficiency furnace and after only 7 years matt was telling us during his service that the circuit board, fan on furnace was shot and that heat pump/airconditioner was operating poorly and was leaking refrigerant. Turned out none of this was true and he was only saying it to keep busy with warranty work.
When Furnace and heat pump were installed the installers ran a jungle of pipes enclosing our hot water tank. When I have to replace the hot water tank next time, our new plumber will have to take apart the mess john mulder made to get it out.
I will never call them for anything ever again!
