not really, sbre. we’ve stuck with fox for yearly inspection of our buderus boiler, because they’re affordable and they toss out coupons pretty regularly. mike blake is their boiler tech, and he’s pretty knowledgeable.
brennan and greenwood heating and air also do boilers.
i could give you the name of the guy who installed ours, because he works pretty cheaply, but i can’t give him a glowing recommendation. i had to vent the boiler through the chimney myself and his pipe welder left a huge mess.
