I don't normally post reviews but thought I would share this as my experience was not as positive as others indicate here. My heater stopped working and the ACS technician diagnosed that I needed to replace the igniter and circuit board at a cost of $1,400 + I would likely need the blower motor to be replaced soon so I might as well go for a whole new system, for a mere $3,500 !!! ACS uses 5 service/repair ""packages"" pre-priced on their invoice that likely include more items than actually need to be done for a given repair and are therefore more expensive than what actual repairs should cost. They offer a nominal discount to these prices if you become a ""Club member"" of their service program. I contacted another company who replaced the igniter for $200, works like a charm. FYI, the ACS invoice ""package"" price for this actual repair would have been $369 ($295 Club member price). This proves that just because you have a BBB approval rating and other certifications, it does not mean you will get an honest diagnosis and/or reasonably priced repairs.
