Signs you're seeing this
- The unit almost never shuts off, even overnight
- The house drifts a few degrees above the setpoint every afternoon
- Electric bills jumped without a change in how you use the system
- The system used to cycle on and off and now simply does not
Some constant running is just Florida in July
An air conditioner is sized to hold your house about 20 degrees cooler than it is outside. When Oviedo hits the upper 90s with a heavy heat index, a correctly sized system can run almost continuously through the afternoon just to hold 76 or 78 inside, and that is working as designed, not a fault. A unit that runs long and steady while keeping the house at the setpoint is actually running efficiently. Short, frequent on-off cycling is often the bigger warning sign. So the question is never really "is it running a lot," it is "is it running a lot and still losing ground."
When constant running is a real problem
It crosses into a fault when the system runs all day and the indoor temperature still creeps above where you set it, or when the runtime clearly jumped compared to past summers. The usual culprits in our area are a dirty condenser coil that can no longer shed heat, a slow refrigerant leak dropping capacity, a clogged filter or coil choking airflow, or leaky attic ductwork bleeding cold air into a 130 degree attic instead of your rooms. Any one of these makes the system work harder for less cooling, which shows up as endless runtime and a higher power bill.
The undersized or aging system case
If the unit is more than 12 to 15 years old, or it was undersized for the home from the start, it may simply be at the end of what it can do on design-day heat. An older system that has lost a few points of efficiency and sits in the Florida sun can reach a point where it never catches up in the afternoon no matter how clean it is. That is a repair-versus-replace conversation, and an honest tech will tell you which side of that line you are on instead of selling you a system you do not need yet.
Get an answer before the bill climbs again
If your AC runs nonstop and the house still will not hold temperature, GRL Air & Heating will measure the refrigerant charge, airflow, and coil condition and tell you exactly why. We run same-day AC repair across Seminole, Orange, Volusia, and Lake counties under Florida CMC license CMC056892, diagnose before we quote, and never start work until you approve it.
