FAQs
How do I know it’s time to replace my HVAC system in Sequatchie?
Most systems last 12-15 years. Warning signs include rising utility bills, uneven room temperatures, loud or unusual noises, frequent repairs, and the use of R-22 (Freon) refrigerant, which is now phased out. A professional load calculation and inspection can confirm whether repair or replacement is the wiser investment for Sequatchie’s humid subtropical climate.
What does a complete HVAC replacement cost in Sequatchie County, and what affects the price?
For a typical 2- to 3-ton heat pump or gas/electric split system, replacement costs usually range from $6,000 to $12,000 installed. Price varies with system size, SEER2/HSPF efficiency ratings, ductwork modifications, smart thermostat upgrades, and local permit fees. High-efficiency variable-speed units cost more up front but can cut energy bills by 20-40% in the Tennessee Valley Authority (TVA) region.
How do I choose the right system size for my home?
Proper sizing is critical. We perform a Manual J load calculation that measures square footage, insulation levels, window orientation, and air leakage. An undersized unit will run constantly, while an oversized unit will short-cycle and leave humidity behind. For most Sequatchie homes, 500-600 sq ft per ton is only a rough rule of thumb—load calculations provide the real answer.
Are there energy-efficiency incentives or rebates available locally?
Yes. TVA’s EnergyRight program often offers rebates for qualifying heat pumps (typically $200-$400). Federal tax credits of 30%—up to $2,000—for ENERGY STAR-rated heat pumps and furnaces are available through 2032. Our team handles the paperwork and provides AHRI certificates to make sure you receive every dollar you’re entitled to.
What should I expect during the HVAC replacement process?
Most replacements take one full day. We start by protecting floors and furniture, then remove the old air handler, condenser, and line set. After installing the new equipment, we evacuate and charge the refrigerant lines, balance the air flow, and pull a county permit inspection. You receive an on-site tutorial, owner’s manuals, and a copy of the final commissioning report.
How do I maintain my new HVAC system to maximize its life span?
Change filters every 30-60 days, keep outdoor coils clear of leaves and grass, and schedule professional maintenance each spring and fall. Preventive service includes cleaning coils, checking refrigerant pressures, tightening electrical connections, and testing safety controls. Routine upkeep can cut energy use by up to 15% and keep your warranty valid for its full 10-12 years.
