This is one of the most common HVAC problems. It’s aptly called short-cycling and is often caused by a malfunctioning thermostat. It can also be a sign of inadequate insulation or flawed installation practices. If your system short cycles the moment it’s installed, your HVAC professional might have given you an under or oversized system. If your insulation and airflow are suboptimal, a simple air filter cleanse might be enough. If your luck has run out, though, you might need a more substantial improvement in your attic and wall insulation.
