Common Questions
Are there new codes for the R-454B refrigerant in the new systems?
Yes. All installations of equipment using mildly flammable A2L refrigerants like R-454B must comply with 2026 safety standards (UL 60335-2-40). This requires a licensed technician to follow strict leak detection, charge limits, and ventilation protocols. In Horry County, the Planning and Zoning Department requires a permit for this work to ensure code compliance and safety for your household and our technicians.
My Ecobee thermostat is showing an 'E1' alert. What does that mean here?
An Ecobee E1 alert indicates the thermostat is not detecting power from your HVAC system's control circuit. In Red Hill, this is frequently caused by a tripped safety switch on the condensate drain pan due to our high humidity, a blown low-voltage fuse from a failing component, or a compromised wire connection from salt-air corrosion. It signals an immediate need for service to prevent further component damage or a complete system shutdown.
My AC just stopped cooling on a hot day. How fast can you get here?
For a no-cool emergency in the Red Hill Residential District, we dispatch from our shop near the Myrtle Beach International Airport. Using US-501, we can typically be on-site within 15 to 25 minutes. Our first priority is to restore cooling, which often involves checking for a tripped breaker, a clogged condensate drain, or a failed capacitor—common issues that can be resolved quickly.
What does the new 14.3 SEER2 minimum mean for my electric bill?
The 14.3 SEER2 federal minimum for 2026 ensures new systems are about 15% more efficient than older standards. At Santee Cooper's rate of $0.13/kWh, upgrading a 3-ton unit from a 10 SEER model can save over $400 annually. Pairing a high-SEER2 system with the active HEEHRA rebate, which offers up to $8,000, significantly improves the payback period, making high-efficiency upgrades very accessible.
Why does my AC struggle when it hits 95°F, even though it's newer?
HVAC systems in Red Hill are engineered for a 93°F design temperature. When ambient temperatures exceed this, as they often do, the system cannot maintain the typical 20°F delta T (temperature drop). The newer R-454B refrigerant performs better in high heat than older types, but all systems lose capacity. Proper sizing from a Manual J load calculation and ensuring clean coils are critical for maximizing performance during peak heat.
My system seems original to my 1994 home. Is it time for a replacement?
A system installed in 1994 is now 32 years old, which exceeds its typical service life by over a decade. In Red Hill, the humid, salt-rich air accelerates corrosion, particularly on the aluminum condenser coil. This corrosion reduces heat transfer, forcing the compressor to work harder and increasing the risk of a costly refrigerant leak or compressor failure. Proactive replacement is often more economical than an emergency repair on a unit this age.
I have electric heat. Should I switch to a heat pump for our mild winters?
Yes, a modern heat pump is highly advisable. Electric resistance heat is very costly, especially during Santee Cooper's peak hours from 2 PM to 7 PM. A heat pump provides heat at about one-third the cost by moving heat rather than creating it, and it functions efficiently in Red Hill's winter lows. This transition also qualifies for the HEEHRA rebate, and the same system provides efficient cooling all summer.
Can my existing ductwork handle a better air filter for ozone and pollen?
Your flexible insulated ducting has limitations. While upgrading to a MERV-13 filter is excellent for capturing April pollen and mitigating ground-level ozone, it increases static pressure. An older blower motor may not overcome this, reducing airflow and causing the system to ice up. A technician should measure your system's static pressure to confirm compatibility before installing high-MERV filters, and a duct modification may be recommended.
