Called HJacks Jamestown, NY for serviceon furnace:just turned 5 yrs. Has a 10 yr warranty -- 5 yr on labour. Arrived at 4 season vacation home at 5 pm, only 45F inside at thermostat set at 58F. Call and get dispatcher/answering service (Be aware of likely tax dodge: dispatcher is actually owner's wife and answers from home). Distressed but agree, when service calls that after hrs service fee is $169, plus hrly rate and parts costs. If there is warranty the office will adjust bill in AM, he says. Wait more than he (I agreed b/c he said he was at sons baseball practice Arrives abt 8 pm, done by 9 pm. Bill $252. Moisture in motor b/c of flawed roof vent -- which H Jack's installed. PVC pipe was letting water in when it rains. Tech quoted on cost of repair or modification. Abt an HR later I realize house not heating. Temp dropped 3 degrees since tech left and I turned off space heaters. Check out batteries in thermostat and make call to report problem just after 10 pm. Get dispatcher, then tech. Same spiel as before$169 plus hrly rate and parts: you have to agree to pay before they come out to fix same furnace that was fixed 90 minutes earlier. Was told I didn't report problem within 30 minutes: had been too long. I freak: but not "dispatcher" and tech Stonewall, leavinge NE with no choice. Freeze or pay. Paying $169 service charge twice in four hours to fix a problem caused by company's flawed work at installation does not seem to be good or fair business practice. Having no recourse/ chain if command for techs after hrs leaves them in cold too. Dispatcher is a barrier, and good at lying: she is closer to owner than she says. And when I called this AM to see if there was any recourse, I got told off by owner ( who is 80 and too old for this nonsense) before I had a chance to present issue. He refused to talk and told us to find another contractor. Too bad, b/c no one else in the vicinity, I've learned. But I am going everywhere I can to warn people abt HJacks overcharging. We were billed $200 last yr to loosen a water filter their techs installed while doing a system flush. After complaining, it was reduced to $100. I see a pattern of charging full prices to fix problems or mistakes they make. BEWARE!!!!
