FAQs
How do I know when it’s time to replace my gas furnace or full HVAC system in Louisville?
Most gas furnaces last 15–20 years, but Louisville’s hot, humid summers and chilly winters put extra stress on equipment. Signs it’s time to replace include frequent breakdowns, uneven temperatures, rising utility bills, noises or odors, and repair costs that exceed 30% of a new system price. A professional load calculation (Manual J) will confirm whether the existing unit is undersized, oversized, or simply at the end of its life.
What size furnace and air conditioner do I need for my Louisville home?
Proper sizing is critical for comfort and efficiency. Contractors use Manual J heat-loss/heat-gain calculations that consider square footage, insulation levels, window type, orientation, and Louisville’s design temperatures (93 °F summer, 19 °F winter). Never rely on square-foot "rules of thumb" or your old unit’s rating; homes often receive tighter windows or insulation upgrades that change the load. An accurately sized system cycles correctly, removes humidity in summer, and saves on energy costs.
How much does HVAC replacement cost in the Louisville area?
Prices vary by efficiency, brand, and installation complexity, but typical ranges are $4,500–$7,000 for a mid-efficiency gas furnace alone, $7,500–$12,000 for a matched furnace and 14–16 SEER2 air conditioner, and $10,000–$15,000 for high-efficiency (95%+ AFUE furnace, 17–20 SEER2 AC) with new ductwork or zoning. Local utility rebates (LG&E offers up to $500 for qualifying high-efficiency units) and federal tax credits (30% up to $600 for furnaces, $2,000 for heat pumps) can cut net cost.
Do I need permits or inspections for HVAC replacement in Jefferson County?
Yes. Louisville Metro/Jefferson County requires a mechanical permit for furnace or AC replacements. Your licensed HVAC contractor files the permit, schedules inspections, and ensures compliance with Kentucky Mechanical Code and local amendments (e.g., flue venting clearances, combustion air, and R-410A refrigerant handling). Skip ping permits can void warranties, homeowners insurance, and resale home inspections.
How long does installation take and will I be without heat or AC?
A straight furnace swap usually takes 4–6 hours; a full furnace/AC change-out with coil, refrigerant lines, and thermostat typically finishes in one full day. If duct modifications, asbestos abatement, or zoning dampers are involved, allow 2–3 days. Technicians disconnect the old unit, set the new equipment, connect gas, electrical, flue, and refrigerant lines, then pressure-test, evacuate, and charge the system. You’ll be without heating or cooling only during the actual change-out window.
What maintenance is required after my new system is installed?
Replace or wash air filters every 1–3 months, keep outdoor condenser coils free of debris, and schedule professional tune-ups twice a year—one heating, one cooling. Louisville’s high pollen and humidity make coil cleaning and drain-line flushing essential to prevent mold and water leaks. Annual service maintains manufacturer warranties, maximizes efficiency, and can catch issues (e.g., cracked heat exchangers) early. Many local contractors offer affordable maintenance plans that include priority service and discounts on repairs.
