Question Answers
With spring pollen and ozone alerts, can my current ducts handle a better air filter?
High-MERV filters combat April pollen peaks and ozone risks, but they increase static pressure. Your flexible R-6 insulated ductwork may not handle a MERV-13 filter without a system assessment. Excessive static pressure from an undersized duct system can reduce airflow, strain the blower motor, and diminish cooling capacity, negating air quality benefits.
I have electric heat strips. Should I consider a heat pump for Hanahan winters?
Switching from electric resistance heat to a modern cold-climate heat pump is advisable. Even with our mild winter lows, heat pumps provide heat at a fraction of the cost of strip heat during Dominion Energy's peak hours (1-7 PM). This shift significantly reduces your kW consumption during the most expensive time of day, offering substantial utility savings.
My Ecobee thermostat is showing an E1 alert. What does this mean for my system?
An Ecobee E1 alert indicates the thermostat is not detecting a call for cooling or heating from your HVAC equipment. In Hanahan, this often points to a control board failure, a blown low-voltage fuse, or a safety lockout due to a fault like low refrigerant from coil corrosion. It requires a technician to diagnose the specific system fault preventing the control signal.
My original system is still running. How much longer can I expect from a unit built in 1988?
A system from 1988 is approximately 38 years old, which is well beyond its design life expectancy. In Hanahan, these aging units face accelerated failure due to coastal salt-air coil corrosion, which aggressively degrades the aluminum fins and copper tubing. This corrosion reduces heat transfer efficiency and often leads to refrigerant leaks. Proactive replacement now prevents a high-probability breakdown during the next heatwave.
What are the permit and safety requirements for a new AC installation in 2026?
All replacements require a permit from the Hanahan Building and Codes Department. Since 2025, new systems using A2L refrigerants like R-454B must comply with updated safety standards (ASHRAE 15, UL 60335-2-40). These mandate leak detection, specific room size calculations, and special contractor certifications for handling mildly flammable refrigerants, ensuring safe installation.
My AC just quit on a hot afternoon in Yeamans Park. How fast can a tech get here?
For a no-cool call in Yeamans Park, a technician can typically be dispatched from near Hanahan City Hall and reach you within 10 to 15 minutes via I-26. This rapid response is critical for protecting your home from the rapid heat and humidity gain that occurs when cooling stops. We prioritize securing the system to prevent further component damage while diagnosing the immediate failure.
Why does my AC seem to struggle on the hottest days, even if it's below 100 degrees?
Hanahan's HVAC systems are engineered for a 92°F design temperature, balancing efficiency and capacity. When outdoor temperatures exceed this threshold, the system operates continuously to maintain setpoint, and the temperature split (delta T) can shrink. Modern R-454B refrigerant maintains better performance and capacity in these high-ambient conditions compared to older refrigerants.
I've heard about new efficiency rules. What SEER2 do I need, and are there rebates?
As of 2026, the federal minimum SEER2 standard for our region is 14.3. Installing a higher-efficiency system, like an 18 SEER2 unit, directly offsets Hanahan's average 13-cent per kWh electricity rate. The active Inflation Reduction Act rebates, with caps up to $8,000, can make the higher initial investment pay off quickly through lower monthly operating costs.
