Questions & answers
How often should I have my AC serviced in Charleston?
“Twice a year — spring before cooling season starts and fall before you switch to heating. Charleston's summers are long and relentless, so going into June with a system that hasn't been looked at since the previous fall is a good way to end up with an emergency repair on a 98-degree weekend.”
Why is my AC running but not actually cooling the house?
“The most common culprits are low refrigerant, a dirty evaporator coil, a failing capacitor, or something restricting airflow — a clogged filter, a closed vent, or a failing blower motor. In Charleston's humidity, a frozen evaporator coil is also something we see regularly, usually caused by low airflow or low refrigerant.”
What size AC do I need for my home?
“We don't answer that without a load calculation. Square footage is a starting point, not an answer.”
How long does an AC system typically last in the Charleston area?
“In standard inland areas like Summerville or Goose Creek, 15-18 years with good maintenance is reasonable. On barrier islands and coastal properties where salt air is a constant factor — Isle of Palms, Kiawah, Sullivan's Island — count on 10-14 years, shorter if the system hasn't had coated coils or regular maintenance.”
Why does my Charleston home feel more humid than it should even with the AC running?
“A few possible reasons. Oversized AC equipment cools quickly but doesn't run long enough to complete a dehumidification cycle.”
What does Phenomenal Aire actually do, and is it worth it?
“Phenomenal Aire uses cold plasma ionization to neutralize airborne bacteria, viruses, mold spores, and VOCs as air passes through your ductwork. It's not a filter — it doesn't capture particles, it deactivates them.”
How often do I actually need my air ducts cleaned?
“Every 3-5 years under normal conditions, but sooner if you've had renovation work (drywall dust gets everywhere), a pest infestation, visible mold, or family members with unexplained respiratory symptoms. Ducts in unconditioned attic spaces in Charleston's climate are particularly vulnerable to moisture-related contamination.”
Do I need a whole-home humidifier in the Lowcountry?
“Probably not in summer. But during winter heating season — especially when we get dry cold snaps and your heating system is running frequently — indoor humidity can drop to uncomfortable levels.”
Will a smart thermostat actually save me money or is it just a convenience thing?
“Both, but the savings are real. Smart thermostats that learn schedules and modulate setpoints typically cut HVAC energy use by 10-15% compared to manual programming.”
Do I actually need a furnace in Charleston, or is a heat pump enough?
“For most Charleston-area homes, a heat pump is enough — and more efficient. Our winters rarely see sustained temperatures below the 35-40°F range where heat pump efficiency starts to drop meaningfully.”
What's the difference between a heat pump and a furnace?
“A heat pump moves heat — it extracts warmth from outside air and moves it inside. It also runs in reverse as an air conditioner in summer, which is why it's the dominant technology in mild climates.”
My heat pump is blowing cool air in heat mode. Is it broken?
“Not necessarily. Heat pumps go through a defrost cycle periodically — the outdoor unit briefly reverses operation to melt any ice that's built up on the coil, and during that cycle, the air inside can feel cooler.”
How do I know if I need heater repair or full replacement?
“We use a simple framework: if the repair cost is under half the replacement cost and the unit is under 12 years old, repair usually wins. If the unit is older, has been repaired multiple times in recent years, or your energy bills have climbed significantly without a clear reason, replacement is usually the better financial decision.”
Why do older Charleston homes have so many plumbing problems?
“The combination of age, coastal groundwater, and original materials. Homes on the Charleston peninsula built before the 1970s often still have galvanized steel supply lines and cast iron drain lines — materials that were standard at the time but have a finite lifespan.”
Do I need a sump pump?
“Depends on your property. Low-lying areas on James Island, Johns Island, parts of North Charleston and Hanahan near wetlands, and anywhere with a crawl space that's seen water intrusion benefit significantly from a sump pump.”
What causes slab leaks and how do you find them?
“In the Lowcountry, the main causes are corrosive soil conditions, aging copper pipes, and pressure fluctuations. A slab leak often announces itself as warm spots on the floor (if it's a hot water line), an unexplained spike in your water bill, the sound of running water when everything is off, or visible cracks in the slab.”
Should I replace my tank water heater with a tankless?
“Tankless has real advantages — unlimited hot water, 20+ year lifespan versus 10-15 for a tank unit, and better energy efficiency. The upfront cost is higher.”
