Why is my HVAC system not cooling (or heating) properly?
Uneven temperatures or poor performance usually stem from airflow problems, thermostat issues, or refrigerant leaks. A dirty air filter is often the culprit — it restricts airflow and causes the system to overwork. Blocked vents, dirty coils, or low refrigerant levels can also prevent efficient heating or cooling. Start by checking the thermostat settings and replacing or cleaning the air filter. If that doesn’t fix it, contact a professional to inspect the coils, blower motor, and refrigerant levels.
