Florence's April pollen peak and seasonal ozone risk make advanced filtration like MERV-13 desirable. However, the flex duct and galvanized steel plenum common in local homes can create high static pressure if not properly sized. A technician must perform a static pressure test before installing a MERV-13 filter; often, the existing ductwork requires sealing or modification to handle the increased airflow restriction without straining the blower motor.

All HVAC replacements in Florence require a permit from the City of Florence Building Inspections Department. As of 2026, installations using the mildly flammable A2L refrigerant R-454B must also adhere to updated safety standards, which include specific leak detectors, revised clearance distances, and special technician certifications. These codes ensure the safe handling of the new refrigerant and are verified by the city inspector during the final permit sign-off.

The new federal minimum standard is now 14.3 SEER2, but modern systems can reach 18-20 SEER2. At Florence's average electric rate of $0.13 per kWh, the higher SEER2 unit significantly reduces operating costs during our long cooling season. The active Inflation Reduction Act rebates, which can cover up to $8,000 of qualified system costs, make the payback period for this efficiency jump much shorter than in previous years.

An Ecobee E1 alert indicates the thermostat has lost communication with the outdoor AC unit. In Florence, this is often caused by a safety lockout from low refrigerant charge due to a micro-channel coil leak, a tripped high-pressure switch from a dirty condenser coil, or a failed control board. It's a specific signal that the system has shut down to prevent damage and requires a professional technician to diagnose the electrical and refrigerant circuit.

For Florence homes using electric heat, a heat pump is a compelling year-round upgrade. Our winter lows are mild enough for modern cold-climate heat pumps to operate efficiently, providing both heating and cooling. To maximize savings, use a thermostat to limit auxiliary electric strip heat usage during Duke Energy's peak rate hours from 2 PM to 7 PM. The combined efficiency and IRA rebates make this transition financially logical for most homeowners.

A no-cool emergency in the summer requires a quick diagnosis of the compressor, capacitor, or refrigerant charge. Our service teams are dispatched from near Florence Veterans Park and use I-95 for direct access to neighborhoods like Highland Park, ensuring we can typically provide a technician on-site within the 12-minute window we quote. This rapid response helps prevent secondary damage from heat and humidity inside the home.

Florence's summer highs can exceed 100°F, but residential systems are engineered for a 93°F design temperature. When ambient temperatures soar past this limit, the system's capacity to remove heat diminishes, causing indoor temperatures to rise. The newer R-454B refrigerant, now standard, maintains slightly better pressure and cooling performance in these extreme conditions compared to older refrigerants, but no system can overcome a design limit deficit.

Homes in Florence built around 1983 have HVAC equipment that is roughly 43 years old, well past its intended 15-20 year service life. This age is a primary factor for the high rate of micro-channel coil corrosion failures we see locally. The combination of our humid air and the natural oxidation of aluminum over decades accelerates this process, often leading to refrigerant leaks and system failure that require a full replacement.
