It depends on the specific fault rather than age alone. Systems under ten years old with a failure isolated to components are usually worth repairing. Approaching fifteen years with repeated failures, compressor degradation, rising energy use, or a leak in a system using a phased-out refrigerant, replacement starts to win on value. We evaluate age, warranty status, and repair history, then present both paths with costs.

Usually restricted airflow, a low refrigerant charge, a dirty coil, or an electrical component failing under load — often more than one at once. Long cycles that never reach the thermostat setting, or humidity that stays high while the system runs, are the classic signs. Because these compound each other, diagnosing the whole system rather than one component matters.

Yes. Total Comfort handles residential systems and commercial equipment including packaged rooftop units, serving offices, retail spaces, medical facilities, restaurants, and multi-tenant buildings throughout Volusia, Flagler, Seminole, and St. Johns counties.

Less than in milder climates, because systems here run for most of the year rather than seasonally. That extended runtime is exactly why maintenance matters more here — with regular service and timely repairs, many systems keep operating efficiently for years despite the conditions. Coastal salt air shortens equipment life further.

Yes. We service major manufacturer equipment regardless of who installed it, including central split systems, heat pumps, packaged rooftop units, ductless mini-splits, and air handlers, using components matched to the system rather than generic substitutes.

Yes, and it is the part most often overlooked. Cooling performance depends on air distribution as much as mechanical operation, so a sound compressor behind restricted ductwork or a neglected filter still produces uneven temperatures, high humidity, and wasted energy. That is why we address both together.
