Common HVAC Problems We Solve in Mount Pleasant
Years of serving the Mount Pleasant community have given us firsthand knowledge of the common issues that affect local HVAC systems. The constant humidity and salty air can take a toll, but our team is prepared to tackle any problem, including:
Air Conditioning Issues:
- AC Blowing Warm Air: This frustrating issue can stem from low refrigerant, a failing compressor, or restricted airflow. We meticulously diagnose the root cause to provide a lasting solution, not just a temporary fix.
- System Constantly Running: An AC that never shuts off is working overtime, driving up your energy bills. This could be caused by an undersized unit, leaky ductwork, or a faulty thermostat.
- Strange Noises or Odors: Grinding, squealing, or banging sounds often signal mechanical problems that require immediate attention. Musty odors can indicate mold or mildew in your ductwork or drain pan, which we can resolve safely.
- Water Leaks and Puddles: A clogged condensate drain line is a common culprit in our humid climate. We’ll clear the blockage and check for other potential sources of leaks to prevent water damage.
- Frozen Evaporator Coils: Ice buildup on your indoor coil is a clear sign of a problem, usually related to poor airflow or low refrigerant. We’ll safely thaw the unit and fix the underlying issue.
Heating System Issues:
- Furnace or Heat Pump Not Heating: Whether it’s a faulty ignitor in your furnace or a reversing valve issue in your heat pump, we have the expertise to restore warmth to your home.
- Pilot Light Problems: If you have a gas furnace, a pilot light that won’t stay lit can indicate a problem with the thermocouple or gas supply, which our technicians can safely repair.
- Frequent Cycling: A heating system that turns on and off too frequently may be overheating or experiencing thermostat issues. We’ll identify the cause to ensure efficient and consistent heating.

Should You Repair or Replace Your HVAC System?
This is one of the most common questions homeowners face. While a repair is often the most cost-effective solution, there are times when replacement is the wiser long-term investment. We provide honest, transparent assessments to help you make an informed decision based on these key factors:
- Age of the System: If your air conditioner or heat pump is over 10-12 years old, or your furnace is over 15, it may be nearing the end of its operational life. Investing in frequent repairs on an aging unit can become a costly cycle.
- Frequency and Cost of Repairs: Are you calling for repairs every season? If your repair costs are adding up, those funds might be better allocated toward a new, reliable, and energy-efficient system. A common guideline is the "$5,000 Rule": if the cost of the repair multiplied by the age of your system exceeds $5,000, replacement is often the better financial choice.
- Energy Efficiency: Older systems are significantly less efficient than modern units. A new, high-efficiency system can drastically reduce your monthly utility bills, providing a return on your investment over time.
- Performance and Comfort: If your system struggles to maintain a consistent temperature, runs too loudly, or fails to control humidity, a new unit can provide a dramatic improvement in your home's overall comfort.
