Sigman Heating & Air Conditioning Inc

Background: Units at the home are 15-16 years old. Average life expectancy of a heat pump is 15 years.  Proposals to replace have been declined twice. Routine maintenance was performed on 6/24/16. The maintenance included the clearing of drain/condensate lines. During normal operation it is...

entirely possible for a debris to clog a drain line, especially when there is extended run times during the summer over a 10 week period. At no time does maintenance on any machine, be it a heat pump/fan coil or a car guarantee perfect operation between inspections, especially as it nears the end of its useful life.
