Purchased a new Trane system through Home Depot on 2/09 to replace the original home system.The original system was reported to be a low quality, unreliable, builders special system but it never broke down over the 8-9 years.To avoid a possible disastrous break-down, the original system was replaced to alleviate any worries.After only 2-3 years, the blower motor and circuit board failed.Labor costs of about $500.00 later.Trane did not care about their inferior product failure even with a disabled family member in the home.Which product was the real inferior one ... the original system that never broke down or the new one that failed in only 2-3 years?The Trane name was heavily advertised as a quality, reliable, efficient system.The new system is as noisy as the old one, utility costs are the highest ever, and it failed already! Absolutely, do not purchase a Trane product unless you desire costly aggravation and a lack of consumer care!!!
