FAQs
How often should my air conditioner be serviced in Charleston’s hot, humid climate?
Because Charleston experiences long cooling seasons and high humidity, we recommend professional maintenance twice a year—once in early spring before peak heat and again in late summer or early fall. Regular tune-ups include coil cleaning, refrigerant level checks, electrical inspections, and drain-line flushing, which together help prevent mold growth, salt-air corrosion, and sudden breakdowns while keeping your energy bills in check.
What size air conditioner do I need for my Charleston home?
Sizing depends on square footage, insulation quality, window count, sun exposure, and local humidity levels. As a rough guide, a well-insulated 2,000-sq-ft Charleston home typically needs a 3- to 3.5-ton system, but coastal humidity often calls for slightly higher capacity or a unit with enhanced moisture control. A Manual J load calculation performed by our technicians ensures your new system is neither undersized (leading to poor comfort) nor oversized (causing short cycling and high humidity).
Should I repair or replace my older AC unit?
Consider replacement when your system is 10–15 years old, uses R-22 refrigerant, needs repairs that exceed 50% of replacement cost, or struggles to maintain set temperatures. New ENERGY STAR models are up to 40% more efficient and include variable-speed compressors that excel at humidity removal—an important benefit for Charleston’s muggy summers. We offer free estimates and financing to help you weigh costs and long-term savings.
How can I reduce indoor humidity and improve air quality?
1) Install a high-efficiency AC with a variable-speed blower that runs longer at lower speeds, pulling more moisture from the air. 2) Add a whole-house dehumidifier set between 45–55% relative humidity. 3) Replace filters every 30–60 days and consider MERV-11 or higher filters for better allergen capture. 4) Have your ductwork inspected for leaks that draw humid attic or crawl-space air indoors. 5) Use kitchen and bath exhaust fans to vent moisture at the source.
Are there energy rebates or tax incentives for high-efficiency AC installations in Charleston?
Yes. South Carolina utilities such as Dominion Energy and Santee Cooper usually offer $200–$700 rebates for replacing a SEER 14 or lower unit with a SEER2 16 or higher model. Federal tax credits under the Inflation Reduction Act provide up to 30% of costs (max $600) for central AC and up to $2,000 for heat pumps meeting ENERGY STAR CEE Tier 2 levels. Our team handles all paperwork and will confirm current promotions before installation.
Why is my AC running but not cooling my home effectively?
Common Charleston-area causes include: 1) Clogged outdoor coils from salt-laden air; 2) Low refrigerant due to leaks aggravated by corrosion; 3) Restricted airflow from dirty filters or collapsed ductwork; 4) Frozen indoor coils caused by low airflow or refrigerant; 5) Thermostat miscalibration in humid conditions. Turn the system off to prevent damage, replace the filter, and check the outdoor unit for debris. If the problem persists, schedule a diagnostic visit so we can locate leaks, clean coils, or recalibrate controls.
