All HVAC installations in Florence County require a permit from the Florence County Zoning and Planning Department. For the mildly flammable A2L refrigerants like R-454B, which is now standard, 2026 codes mandate specific safety protocols. These include installing leak detectors in the equipment cabinet, using label-compliant flare fittings, and ensuring proper ventilation in mechanical rooms. Your contractor must verify the system's charge and leak test it according to these updated standards before inspection, which is a critical step for both safety and system longevity.

Florence homes average about 73 years old, so many original or replacement systems are well beyond their typical 15-year design life. Age-related wear on components like capacitors, contactors, and refrigerant seals is the primary factor. In Florence, the extreme temperature swings between seasons place additional thermal stress on these aging parts, making the evaporator coil particularly susceptible to developing small refrigerant leaks or airflow blockages that lead to freezing.

Given Florence's 16 cents per kWh rate, upgrading from a pre-2023 10 SEER system to a new 16+ SEER2 unit can cut cooling electrical use by over 30%. The federal Inflation Reduction Act rebates, active with an $8,000 cap, directly offset a significant portion of the equipment premium. When combined with Focus on Energy incentives up to $2,000, the net investment often achieves a payback period that aligns with the system's operational lifespan.

Galvanized steel ductwork is structurally sound, but its original design did not account for high-static-pressure MERV-13 filters. Installing such a filter without assessing static pressure can severely restrict airflow, leading to frozen coils and reduced capacity. A technician should measure the external static pressure of your system. Often, the solution involves sealing existing duct leaks and potentially upgrading the blower motor to a variable-speed model that can compensate for the added filter resistance while effectively capturing particulates from smoke and May pollen peaks.

A technician based in Florence City Center can typically be en route within minutes. Using US-2 for direct east-west access, the drive to most homes near the courthouse is a predictable 5 to 10 minutes. We prioritize no-cool calls during heat events, dispatching with diagnostic tools and common replacement parts for systems of your home's era to begin restoration immediately upon arrival.

An 85°F design temperature is the standard engineering baseline, meaning the system is sized to maintain a 75°F indoor temperature when it's 85°F outside. On days reaching the low 90s, the system will run continuously to maintain temperature, which is expected. Modern systems using R-454B refrigerant maintain better efficiency and capacity at these elevated temperatures compared to older R-410A units. Proper sizing via a Manual J load calculation is critical to ensure it can handle the load without short-cycling on milder days.

For Florence homes, a cold-climate heat pump is a viable primary heating source, especially with winter lows that typically stay within modern equipment capabilities. The economics are compelling: switching from propane to a heat pump for heating can reduce your cost per BTU by over 50%, given local utility rates. To maximize savings, operate the heat pump during off-peak hours outside the 2 PM to 7 PM window. The existing propane system can be retained as a cost-effective backup for the coldest periods, creating a highly resilient hybrid system.

An Ecobee E162 alert specifically indicates a loss of communication between the thermostat and the outdoor heat pump unit. In Florence, this is often traced to a tripped high-pressure switch or a low-voltage wiring issue exacerbated by temperature-driven expansion and contraction in the lineset. This alert prevents the system from running to avoid damage. The first step is a visual check at the outdoor unit for any obvious fault codes or tripped breakers, which helps a technician diagnose remotely and bring the correct components for repair.
