Could a dirty filter cause my AC to run constantly?

Yes. A clogged filter restricts airflow across the evaporator coil, reducing cooling capacity and forcing the system to run longer. Replacing a dirty filter is the single most common fix and should be checked first.

How do I know if my AC is undersized for my home?

An HVAC contractor can perform a load calculation (Manual J) to determine whether your system is properly sized for your home's square footage, insulation, windows, and climate. An undersized system will run constantly on hot days and never reach the set temperature.

My AC Keeps Running Constantly

An AC that runs constantly in Florida heat is working harder than it should. Common causes include a dirty air filter, a thermostat set too low, restricted airflow, low refrigerant, or an aging system that can no longer keep up. An HVAC contractor can diagnose the real cause.

What to Do Right Now

The AC runs continuously or cycles on and off far more than usual, and the home still may not reach the set temperature.

Check the thermostat — make sure it is set to "auto" (not "on") and the temperature is not set extremely low

Check and replace the air filter if it is dirty — a clogged filter restricts airflow and forces the system to run longer

Make sure supply and return vents are open and not blocked by furniture

Check whether the outdoor condenser unit is clear of debris, plants, or overgrowth

What Not to Do

✗Don't set the thermostat lower than 72°F trying to force cooling — it makes the system run longer without fixing the cause

✗Don't open windows or doors while the AC is running — that adds heat load

✗Don't assume the system just needs more refrigerant without a professional finding the cause

When to Call a Professional

Call an HVAC contractor if the filter is clean, the thermostat is set correctly, vents are open, and the AC still runs constantly. In Florida's heat, a system that runs nonstop may be undersized, low on refrigerant, or failing — all of which need a professional diagnosis.
