Service was good , problem was with promise from sales advisor , when deal was made for the furnace a/c i was promised an upgrade on water heater and free chimney liner , water heater was already 18 yrs old , almost three months passed with no heater or free liner , this passed fri. the heater decided to flood my finished rec. room , emailed advisor Eren who said to contact him with any needs , he says to use the 800 # , won't answer phone or return messages , i then had to take on a new pv 40 instead of conventional like i was promised at extra $$ , ruined carpet , no hot water for two days , hassle of the whole ordeal , all because my deal was not kept by sales advisor , new heater install went great , the tech Troy was very courteous
