3 zone system in townhome. Blower motor was failed. System is improperly zoned and pressures are extremely high when two zones out of the three are closed. Strongly recommend replacing with variable speed system. System is 10 years old, the average lifespan of a heat pump is about 8 to 12 years under the conditions that it is under with zoning. Witnessed pressures over 500 psi with two zones closed. Clear drain line, however, drain line was very bad and there is no wet switch on system so this may be a flood risk.
