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

During a summer inspection we test the air conditioning under real operating conditions, running the system, measuring its cooling performance, and evaluating the condition of its major components, which makes summer the one season Minnesota AC can be fully assessed. We operate the system from the thermostat and let it run long enough to perform, then check the temperature drop across the evaporator coil, a core indicator of whether the system is cooling as it should. Outside, we inspect the condenser unit for age, corrosion, fin damage, level mounting, and clearance; inside, we examine the evaporator area, refrigerant line insulation, and condensate drainage, 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.
