AC Repair FAQ — Polk County, FL

Generally, if your system is under 10 years old and the repair cost is less than 50% of the replacement cost, repair usually makes sense. If your unit is over 12–15 years old and needs a major repair, replacement is often the better investment — especially in Florida where AC runs almost year-round. Top Notch Air Conditioning & Heating always gives you an honest assessment with both options and their costs before you decide.

Common causes include a refrigerant leak, dirty evaporator or condenser coils, a failing compressor, a frozen evaporator coil from restricted airflow, or a bad capacitor or contactor. The only way to know for sure is a proper diagnostic by a certified technician. Call Top Notch Air Conditioning & Heating at (863) 875-5500 and we can typically diagnose the issue the same day.

We typically have appointments available same-day or next-morning throughout Polk County. During peak summer demand, Yeti Club members receive priority scheduling, meaning they move to the front of the queue even during our busiest periods. Call (863) 875-5500 Mon–Sat 8 AM–5 PM.

Different noises point to different problems. Grinding or screeching often indicates bearing failure in the blower motor or condenser fan. Banging or clanking can mean a loose or broken component inside the compressor. Clicking repeatedly during startup may be a relay problem. Hissing near refrigerant lines could indicate a leak. None of these should be ignored — call us for a diagnostic before a minor issue becomes a major one.

A tripped breaker is usually a sign of an electrical problem — common causes include a failing capacitor, a locked-rotor compressor that's drawing too much current, wiring issues, or a compressor starting to fail. Never just keep resetting the breaker without finding the cause; you risk damaging the compressor or creating a fire hazard. Our technicians carry common electrical components on their trucks for same-visit repairs.

Ice on your AC is a symptom, not the root problem. It's typically caused by restricted airflow (dirty filter, blocked return vents, low blower speed) or low refrigerant charge. If you see ice, turn the system to “fan only” to let it thaw, and check your air filter first. If the problem recurs, call Top Notch Air Conditioning & Heating — running a frozen system causes compressor damage that leads to expensive repairs.

Modern residential AC systems use R-410A or the newer R-32/R-454B refrigerants, which are not toxic in typical exposure amounts but are not meant to be inhaled in large quantities. More importantly, a refrigerant leak means your system is losing efficiency, damaging your compressor through insufficient lubrication, and venting substances that harm the environment. EPA regulations require licensed technicians to repair leaks before recharging — we always find and fix the leak, not just top off the charge.
