Your flexible R-6 insulated ducts can typically support a MERV-13 filter, which is effective for April's pollen peak and ozone risk. However, the increased static pressure from a higher-MERV filter must be calculated. An undersized return duct or a restricted plenum can cause airflow starvation, reducing cooling capacity and increasing energy use, so a static pressure test is recommended before upgrading.

All installations in Florence County require a permit from the Building Codes Department. For systems using the new A2L refrigerants like R-454B, which are mildly flammable, 2026 codes mandate specific leak detection systems, updated service port requirements, and specialized technician certification. These standards ensure safe handling and are verified by the county inspector during the final permit sign-off.

With an average home built around 1981, many original or second-generation systems are approaching 45 years old. Units this old often face significant refrigerant leaks due to metal fatigue and degraded seals. The high humidity profile here accelerates the most common failure point: microbial growth and corrosion on evaporator coils, which reduces efficiency and can lead to compressor failure if left unchecked.

Given our winter lows and electric as the primary fuel, a modern cold-climate heat pump is highly efficient. It provides both heating and cooling, operating at over 300% efficiency compared to electric resistance heat's 100%. Programming it to avoid the 1-7 PM utility peak hours maximizes savings. The combination of lower operating costs and available HEEHRA rebates makes the transition financially sound.

An Ecobee E1 alert indicates the thermostat cannot detect a call for cooling or heating from your HVAC equipment. In Timmonsville, this often points to a failed control board, a blown low-voltage fuse, or a safety switch trip—issues exacerbated by our high humidity causing corrosion on electrical connections. It's a signal to check the air handler's internal components before a complete system shutdown occurs.

The 2026 SEER2 mandate ensures new systems use about 15% less energy than older 13 SEER models. At Timmonsville's average rate of $0.14 per kWh, a properly sized 3-ton unit can save over $100 annually. The federal HEEHRA rebate, with a cap of $8,000 for qualified heat pumps, directly reduces your upfront cost, while Duke Energy's Smart Saver program offers an additional $300 incentive.

For a no-cool emergency, we prioritize dispatch from our service hub near the Timmonsville Municipal Complex. Located just off I-95, this central position allows for a consistent 5-10 minute response to most homes in the downtown area. We keep trucks stocked with common parts, including R-454B refrigerant, to begin diagnosis and repair immediately upon arrival.

The 92°F design temperature is an engineering standard for capacity, not a limit. On days exceeding this, which are common, the system must run longer to maintain temperature, reducing its latent capacity for dehumidification. The newer R-454B refrigerant maintains better pressure-temperature relationships in this extreme heat compared to older R-410A, offering more stable performance during peak loads.
