Yearly maintenance resulted on me paying for replacement of the aquastat relay on my Bryan boiler, second time on a year and half, since it was previously replaced on 2/2019, it should of be included on serviced guarantee, what type product is this company selling. Part that cost 240.00 at Home Depot I paid 254.00 at least labor was included after me pleading my case, but it will be originally 600.00 for labor to total 854.00 + taxes, what a rip off.
