FAQs
When should I consider a full HVAC system replacement instead of another repair?
You should start planning for a full replacement when your furnace or air-conditioner is 12–15 years old, requires frequent or costly repairs, no longer keeps the house comfortable, or has a SEER/HSPF rating far below today’s efficiency standards. In Cookeville’s humid summers and cool winters, an aging unit can add 20–30 % to your utility bills and struggle with humidity control. Replacing the entire system—both the outdoor condenser/heat pump and indoor furnace or air handler—ensures all components are matched for peak performance and warranty coverage.
What size and type of system is best for homes in Cookeville?
Proper sizing depends on your home’s square footage, insulation levels, window layout, duct design, and local design temperatures (around 92 °F summer / 17 °F winter for Cookeville). During our in-home assessment we perform an ACCA Manual J load calculation to determine the exact BTU and tonnage required. Many Cookeville homes benefit from 14–18 SEER2 central air conditioners paired with 80–96 % AFUE gas furnaces, or dual-fuel heat pump systems that switch to gas heat below about 35 °F. We’ll recommend the best option for comfort, efficiency, and budget.
How much does a complete furnace and air-conditioning replacement cost in the Cookeville area?
Pricing varies with equipment efficiency, capacity, duct modifications, and accessory options (such as smart thermostats, indoor-air-quality add-ons, or zoning). For a typical 2,000 sq ft home, expect: • 14–15 SEER2 AC + 80 % gas furnace: $8,000–$10,000 installed • 16–17 SEER2 AC + 96 % gas furnace: $10,500–$13,500 installed • High-efficiency heat pump / dual-fuel: $11,000–$14,500 installed These figures include new indoor coil, refrigerant line set flush or replacement, pad, whip, disconnect, thermostat, labor, permit, and haul-away. We provide a firm, written quote after the load calculation and site inspection.

How long will the installation take and will I be without heating or cooling?
Most standard replacements are completed in a single day. We schedule 8 a.m. arrival, remove the old system before lunch, set new equipment in the afternoon, and perform start-up/quality checks by early evening. If extensive duct or electrical work is needed, it can extend to two days. We coordinate timing to minimize downtime; during summer or winter extremes we provide temporary heaters or portable AC units at no charge so you are never completely without comfort.
Are rebates, tax credits, or financing options available for Cookeville homeowners?
Yes. High-efficiency systems that meet ENERGY STAR criteria may qualify for: • Federal Inflation Reduction Act tax credit: up to 30 % of project cost, capped at $600 for qualifying AC/heat pumps and $600 for furnaces, or up to $2,000 for heat pumps meeting the highest tier. • Tennessee Valley Authority (TVA) or Upper Cumberland EMC rebates when available—typically $150–$400 for heat pumps. • Manufacturer instant rebates during promotional periods (often $300–$1,200). We also offer 0 % APR financing for 12–18 months or low-interest plans up to 120 months through Synchrony and TVA EnergyRight.
