Based on our findings today, it might be time to think about getting a brand new system. Upon arrival customer stated her thermostats are not consistently keeping the house at the temperature it is set to. The wiring in the zone board seems correct and the zone dampers are opening when called to do so. Noticed the liquid was colder than the suction line and sweating in the attic. The system is zoned, but has a psc blower motor instead of an ecm motor. Blower wheel is dirty. Drain line does not have the correct pitch. There is lots of biological growth in the system. The condenser motor is hot to the touch. The reversing valve is bad. Gave options to repair and to get a quote to replace. Homeowner wants to get a quote to replace, but she’s very busy this week and won’t have time to get that quote until next week.
