From initial contact to final verification — here is how we handle hvac installation.
KIC Refrigeration begins every HVAC installation in Lexington, SC with a detailed in-home survey and ACCA-compliant Manual J load calculation. We account for your home envelope, duct losses, infiltration, occupancy, and the local SC design temperatures for both heating and cooling seasons.
Based on load calculations and your priorities — efficiency, noise level, budget, zoning — we recommend specific equipment and provide a detailed written proposal covering equipment model numbers, SEER2/AFUE ratings, installation scope, warranty, and total cost.
At your Lexington property, our team removes the old system, installs the new equipment on proper mounting and supports, connects refrigerant lines with nitrogen-purged brazing, wires all components to code, installs the thermostat, modifies ductwork as needed, and cleans up completely.
KIC Refrigeration commissions every HVAC installation in Lexington, SC with a documented startup procedure. We record all operating pressures, temperatures, airflow readings, and gas manifold pressures on a commissioning form. We register the warranty, explain seasonal maintenance, and provide a complete documentation package.

Complete HVAC installation in Lexington ranges from $7,000 to $15,000 for a mid-efficiency furnace and AC combination — typically an 80 percent AFUE furnace paired with a 14.3 to 16 SEER2 condenser. High-efficiency systems with variable-speed blowers and two-stage or variable-speed compressors run $12,000 to $22,000 but deliver significantly lower operating costs and qualify for federal tax credits. Heat pump systems fall between $5,000 and $18,000 depending on whether the system is single-stage, variable-speed, or a dual-fuel configuration. Ductwork modifications or new duct runs add $1,000 to $5,000. KIC Refrigeration provides detailed written proposals for Lexington homeowners with every cost itemized and no hidden fees.
Yes, substantially. Replacing a 10 SEER air conditioner with a 16 SEER2 unit reduces cooling energy consumption by approximately 38 percent. Upgrading from an 80 AFUE furnace to a 96 AFUE condensing furnace saves 16 cents of every heating dollar — the old furnace sends 20 cents up the flue while the new one captures it. Combined with proper installation practices — correct refrigerant charge verified by superheat and subcooling, proper static pressure and airflow at 400 CFM per ton, sealed duct connections, and a programmable thermostat — a new system typically saves Lexington homeowners $600 to $1,800 per year depending on home size, usage patterns, and local energy rates.
A standard furnace and AC replacement in Lexington takes 1 to 2 days when existing ductwork, gas piping, and electrical service are adequate and the new equipment fits in the same location. A complete system replacement that includes ductwork modifications, new trunk lines, equipment relocation from basement to attic or vice versa, electrical panel upgrades, or zoning system installation may take 3 to 5 days. Multi-zone mini-split installations with 3 to 5 indoor heads typically take 2 to 3 days. KIC Refrigeration provides a clear timeline in every proposal, coordinates scheduling around your Lexington home availability, and keeps you informed on progress every step of the way.
Correct HVAC system sizing is determined by a Manual J residential load calculation — the ACCA industry standard — that accounts for your home square footage, ceiling height, insulation R-values, window area and U-factor, air infiltration rate, duct losses, occupancy, and the local SC winter and summer design temperatures. As a rough reference, a well-insulated 2,000-square-foot home in Lexington typically needs a 2.5 to 3.5 ton system, while a poorly insulated home of the same size may need 4 tons. KIC Refrigeration never estimates by rule of thumb — we run a proper calculation for your specific Lexington home to avoid oversizing, which causes short cycling, high humidity, and premature compressor wear.
