The new boiler I bought from them is unable to heat my home if the temperature drops below 2 degrees. They claim the boiler is more powerful than my old boiler but it does not heat my home when it is cold. They claim an outdoor thermostat that is provided by Veissman does not work. They did try to resolve the problem, but when they couldn't figure it out they just abandoned the situation unresolved. I had another company come in, they indeed said the boiler would heat this house and then some, but Coleman installed incorrectly. Coleman used piping that was too small, pumps in wrong spots, thermostat incorrectly installed and many, many other issues. I called Gandy & they corrected everything and it works great now, with NO thanks whatsoever to COLEMAN. They eventually went bankrupt and now are trying to resurrect themselves. BEWARE
