Your AC can run but not cool if airflow is blocked, the thermostat is set wrong, or the system has a refrigerant or coil problem. Dirty filters, a clogged outdoor condenser, or leaky ductwork also reduce cooling. If it’s cycling but lukewarm, the coil may be iced or the charge low.
Quick checks:
- Set thermostat to Cool and lower 3–5 degrees.
- Replace/clean the filter.
- Clear leaves/debris around the outdoor unit.
- Look for ice on lines; if iced, turn system off and run Fan.

The “$5,000 rule” is a rough guideline people use to judge repair vs. replacement, but it’s not a substitute for a professional diagnosis. We recommend an on-site inspection to compare current repair needs, system age, and efficiency so you can choose confidently. Our certified technicians provide upfront pricing and 24/7 service, and can review repair and replacement options for your home in Charleston and nearby cities.
Quick checks:
- Consider system age and maintenance history.
- Compare repair cost with likely future repairs.
- Weigh energy efficiency and comfort goals.

We don’t publish a fixed “$5,000 rule.” Some homeowners use it as a rule of thumb: multiply your system’s age (in years) by the repair estimate; if that total is over $5,000, they consider replacement. We don’t apply it as a blanket policy. We assess your system on site, then give transparent, upfront pricing and options that fit your home and budget in Charleston and nearby areas like Moncks Corner.
Quick checks:
- Know the system age.
- Get a written repair estimate.
- Compare efficiency, warranty, and comfort benefits of replacement.

HVAC repair usually includes a full system diagnosis, targeted part replacement, cleaning, safety checks, and performance tuning to restore heating or cooling. Most visits begin by finding why airflow or temperature dropped, often from a failed capacitor, dirty coil, or a thermostat fault. Our technicians serving the North Charleston area follow a step by step process built for clear findings and quick fixes. We service all major brands and frequently complete repairs the same day. A seasoned tech checks static pressure before adding refrigerant because poor airflow can look like a low-charge problem.
Typical tasks during an HVAC repair visit:
- Electrical testing of capacitors, contactors, motors, and safety switches with a meter.
- Refrigerant assessment using pressure/temperature readings with superheat or subcool verification.
- Airflow and duct checks, including static pressure, blower speed, and filter condition.
- Component cleaning and calibration, then a final run test and homeowner walkthrough.
If you notice burning smells, ice on lines, or breaker trips, turn the unit off and schedule service to prevent bigger repairs.

Same-day HVAC repair from Fix-it 24/7 is quoted as an upfront flat-rate after diagnosis, so the price varies by the part and work required rather than by the hour. The biggest cost driver is which component failed, since a simple electrical fix costs less than replacing major parts like a compressor or blower motor. We offer same-day diagnostics in the Mount Pleasant area and provide the exact repair price before work begins. You may also see savings from current offers like $60 OFF any HVAC repair, and Green Club members receive a 15% discount on repairs; first-time customers can book a $39 HVAC Tune-Up & Deep Clean, which is separate from repair. Final pricing is confirmed after an on-site inspection, and we use flat-rate, no-surprise pricing with a $0 Service Call for Repairs.
Key factors that change repair cost:
- Specific part needed and availability
- System type and age (heat pump, furnace, mini-split)
- Accessibility of the component and labor time
- After-hours or holiday timing for emergency service A seasoned tech will also check for root causes so you don’t pay twice for the same issue.
If you notice burning smells, repeated breaker trips, or icing, shut the system off and schedule service to prevent further damage.
