What is the 3 minute rule for AC?

The 3-minute rule for air conditioners is a guideline to wait at least three minutes after turning your AC off before turning it back on, allowing refrigerant pressure to equalize and preventing serious strain and potential damage to the compressor from hard restarts, which can save you costly repairs and extend the unit's life. This crucial pause ensures the compressor doesn't have to fight against high internal pressure, a common cause of failure, though many newer units have built-in timers (anti-short-cycle) to handle this automatically.

Why does my house feel cold at 72 degrees?

If your house feels cold at 72°F, it's usually due to poor insulation, air leaks (windows/doors), unbalanced ductwork, or the thermostat being in a warm spot, causing the system to underheat; cold exterior walls also draw heat away, making it feel chillier, especially in winter, even with the heat running. Fixing drafts, improving insulation, and ensuring proper airflow are key solutions, rather than just cranking the heat, notes PV Heating, Cooling & Plumbing.
