How do you evaluate air conditioning during a summer inspection in Minnesota?

Summer is the one season Minnesota AC can be fully assessed, since the system can be run under real operating conditions, with cooling performance and the condition of major components in view. An air conditioning system needs to run long enough to perform, and the temperature drop across the evaporator coil is a core indicator of whether it is cooling as it should. Outside, the condenser unit is worth reading for age, corrosion, fin damage, level mounting, and clearance; inside, the evaporator area, refrigerant line insulation, and condensate drainage matter, since clogged condensate lines cause a surprising share of ceiling stains under attic air handlers. We note the unit's age against typical lifespan, Minnesota condensers often last a long time because our cooling season is short, but compressors from decades past are still living on borrowed time, and we flag anything warranting a licensed HVAC contractor's deeper evaluation. Worth knowing: when outdoor temperatures are too cold, roughly below the 60s, running an AC risks compressor damage, so off-season inspections get a visual-only AC evaluation, clearly noted in the report.
