System is a 3.5 ton heat pump with zoning. Very limited access crawl space. Capacitor testing good. Pressures were 98/485 and rising indicating an airflow issue. Found dirty air filter and upon inspection found even more impacted evaporator coil. Air handler is a Goodman from 2013 and the heat pump is a Rheem from 2020. Coils are not accessible for service and only 6” away from a concrete pillar. Recommend new system that is variable speed. Customer is turning crawl space into a basement and will be finished estimated about 6 months time from now. He is hoping to redo air handler and make vertical once basement is complete. At that time we will be able come back out and quote a new system.
