If there was a way to give NEGATIVE stars I would! DO NOT use this person! He is incompetent and hard to deal with. Took him 1 1/2 weeks to install my heater, in the FREEZING winter we've had.....THEN, he neglected to put the converter on it to convert the unit from using natural gas to using propane, which I didn't realize until I had burnt up a tank of gas! (oh, but he'll come put it on.....five days after I called him about it!) He charged for things he did not do! Consumers BEWARE!!!!! This will be your WORST NIGHTMARE! Don't waste your money on this company, use a better one to start with, instead of having to get someone else to fix what he does wrong!!!
