FAQs
What qualifies an air conditioner as “high-efficiency” and how is it different from a standard unit?
High-efficiency air conditioners use advanced compressor technology, larger coils, and smarter controls to deliver the same cooling with less electricity. In practical terms, a unit is considered high-efficiency when its SEER2 (Seasonal Energy Efficiency Ratio, updated 2023) rating is 16 or higher—well above the federal minimum of 13.4 SEER2 for most residential equipment. The higher the SEER2 number, the less energy the system needs to keep your home comfortable, which translates into lower utility bills and reduced environmental impact.
Why is high-efficiency equipment especially beneficial in Charleston’s climate?
Charleston experiences long stretches of heat and humidity from April through October. High-efficiency systems often include variable-speed compressors and multi-stage fans that can run at low speeds for extended periods, removing more moisture while consuming minimal power. Better humidity control not only improves comfort, it discourages mold growth and protects wood floors, antiques, and other moisture-sensitive belongings common in historic Lowcountry homes.
How much can I save on energy costs by upgrading to a high-efficiency air conditioner?
Savings vary with usage patterns, house size, and insulation, but Charleston homeowners moving from a 10-12 SEER unit to an 18 SEER2 model typically cut cooling costs 30–40 %. For a 2,000-square-foot home that spends roughly $150 per month on summer electricity, that’s $45–$60 in monthly savings. Over a 12–15-year lifespan, the reduction in utility bills usually outweighs the higher upfront price of the equipment.
Are there rebates or tax incentives available in Charleston for high-efficiency AC installations?
Yes. Duke Energy Progress and Dominion Energy South Carolina both offer rebates—often $200–$600—when you install qualifying high-efficiency heat pumps or central AC systems. In addition, the federal Inflation Reduction Act (IRA) provides a 25C tax credit worth up to 30 % of equipment and labor costs, capped at $600 for an air conditioner or $2,000 for a heat pump. Some high-efficiency models also qualify for upcoming point-of-sale rebates through the HOMES and HEEHR state programs. Our team will handle the paperwork and verify eligibility before installation.
What maintenance does a high-efficiency system require?
Even the best equipment loses efficiency if it’s not properly maintained. We recommend two tune-ups per year—one in spring before heavy cooling season and one in fall before heating season if it’s a heat pump. Service includes cleaning coils, checking refrigerant charge, calibrating thermostats, flushing condensate lines (vital in humid Charleston), and inspecting the blower motor. Between visits, homeowners should replace or wash air filters every 30–60 days and keep outdoor units free of leaves and debris to maintain unobstructed airflow.
How long will installation take and what should I expect?
Most residential change-outs are completed in a single day. We begin with a load calculation to ensure the new system is correctly sized for your home’s square footage, insulation, and sun exposure. On installation day, technicians remove the old equipment, set the new condenser on a leveled pad, install a matching indoor evaporator coil or air handler, connect refrigerant and electrical lines, and pressure-test the system. We finish by evacuating and charging the unit with factory-specified refrigerant, programming your thermostat, and performing a full system test. Finally, we review operating tips and register your equipment for its manufacturer warranty—typically 10 years on parts and compressor when you maintain annual service.
