Air Conditioning
AC is running but air from the vents is warm, not cold.
Diagnose →AC runs constantly but the house never reaches the setpoint temperature.
Diagnose →AC is completely unresponsive — no fan, no hum, nothing.
Diagnose →AC has started making unusual noises — buzzing, banging, clicking, or screeching.
Diagnose →Water is dripping or pooling around the indoor air handler.
Diagnose →AC turns on, runs briefly (under 10 minutes), shuts off, then restarts shortly after.
Diagnose →AC runs continuously without ever shutting off, even when the house feels cool.
Diagnose →Ice has formed on the indoor evaporator coil or the outdoor suction line.
Diagnose →AC trips the breaker shortly after starting, or repeatedly throughout the day.
Diagnose →Outdoor unit hums but the fan blade isn't spinning, or fan stopped working entirely.
Diagnose →AC produces a musty, moldy, or 'dirty socks' smell whenever it runs.
Diagnose →AC produces a burning smell — electrical, plastic, rubber, or chemical.
Diagnose →Water dripping from the ceiling or visible from your attic AC unit.
Diagnose →Loud or persistent humming sound from indoor or outdoor HVAC equipment.
Diagnose →Visible dust blowing out of supply vents or settling rapidly on surfaces.
Diagnose →AC produces a whistling, hissing, or high-pitched sound from vents or the unit itself.
Diagnose →AC making clicking sounds — either rapid clicks, intermittent clicks, or clicking without starting.
Diagnose →Thermostat is set to COOL and shows a call for cooling, but the AC doesn't turn on.
Diagnose →Most of the house cools fine but one specific room stays warm or hot.
Diagnose →Thermostat displays active cooling icon/indicator, indoor blower runs, but no cold air comes out.
Diagnose →Significant temperature differences between rooms despite a single thermostat — some too cold, others too warm.
Diagnose →AC is cooling but indoor air feels sticky, clammy, or humid — humidity above 60%.
Diagnose →Electric bill increased significantly without changes in usage patterns or weather.
Diagnose →Air coming from supply vents is noticeably weaker than normal — barely moving even with system running.
Diagnose →Compare the two opposite HVAC runtime issues to identify which one applies and how to fix.
Diagnose →Furnace / Heating
Furnace blower runs but air coming out of vents is cold or lukewarm.
Diagnose →Furnace runs through its startup sequence but burners never light.
Diagnose →Furnace turns on, runs briefly, shuts off, repeats — rapid on/off cycles.
Diagnose →Furnace burners light but no warm air comes out of the vents.
Diagnose →Standing pilot light won't stay lit, or relights but goes out repeatedly.
Diagnose →Loud bang, boom, or pop when the furnace starts up or cycles.
Diagnose →Rotten egg or sulfur smell coming from or near your furnace.
Diagnose →Burning smell coming from vents or near the furnace.
Diagnose →Indoor blower fan runs constantly, never shuts off between cycles or when heating isn't called for.
Diagnose →Furnace lights and runs for several minutes, then shuts itself off — different from short cycling.
Diagnose →Indoor blower fan operates normally but the furnace never produces warm air.
Diagnose →Furnace produces rattling, buzzing, or vibration sounds during operation.
Diagnose →Pilot light or burner flame burns yellow, orange, or flickering instead of steady blue.
Diagnose →Furnace makes clicking sounds at startup but burners never ignite — usually the gas valve trying repeatedly.
Diagnose →Heat Pump
Heat pump runs but the air coming from vents is cool or only slightly warm.
Diagnose →Heat pump running in cooling mode but no cold air, or much weaker than expected.
Diagnose →Outdoor heat pump unit is covered in ice or frost that won't clear.
Diagnose →Heat pump compressor running continuously without cycling off.
Diagnose →Auxiliary heat indicator shows constantly on the thermostat, even in mild weather.
Diagnose →Heat pump set to heating mode but air from vents is cool, lukewarm, or cold.
Diagnose →Heat pump outdoor unit producing loud noise — buzzing, knocking, vibrating, or whirring louder than normal.
Diagnose →Heat pump outdoor unit not running defrost cycles — ice accumulates instead of being cleared.
Diagnose →Thermostat
Thermostat display is blank, frozen, or completely unresponsive.
Diagnose →Thermostat shows a temperature that doesn't match the actual room temperature.
Diagnose →Thermostat setpoint changes on its own without you touching it.
Diagnose →Thermostat displays normally with correct mode set, but neither cooling nor heating activates.
Diagnose →
