FAQs
How do I know when my HVAC unit in Guild needs to be replaced rather than repaired?
Key warning signs include frequent breakdowns (more than two major repairs in a season), rising energy bills despite regular maintenance, uneven temperatures or humidity issues, and equipment age—most heat pumps and air conditioners last 10–15 years and furnaces about 15–20. If repair costs exceed 40–50 % of the price of a new system or the unit still uses R-22 refrigerant, replacement is usually the most cost-effective route.
What size HVAC unit do I need for my Guild-area home?
Proper sizing is based on a Manual J load calculation that factors in square footage, insulation levels, window types, sun exposure, airtightness, occupancy, and local Guild weather data. A rule of thumb such as “1 ton per 500 sq ft” can lead to oversizing, short cycling, and higher energy use. Ask your contractor for a written load calc; the result may range from 1.5 – 5 tons for typical single-family homes in Guild.
How long does a full HVAC replacement take and will I be without heating or cooling during that time?
Most residential change-outs are completed in one day. The crew will shut off power, recover refrigerant, remove the old equipment, set the new indoor and outdoor units, connect refrigerant lines and electrical, pressure-test, evacuate, and charge the system before restoring power. You’ll be without heating/cooling for 4–10 hours, so plan accordingly. Larger homes, duct modifications, or code upgrades (electrical panel, condensate drains) can add an extra day.
Are there energy-efficient options and incentives available in Guild when replacing my HVAC system?
Yes. Look for ENERGY STAR-rated heat pumps (SEER2 ≥ 15.2, HSPF2 ≥ 8.1) or furnaces (AFUE ≥ 95 %). The Tennessee Valley Authority (TVA) eScore program and federal Inflation Reduction Act (IRA) tax credits can provide up to $2,000 for heat pumps or 30 % of costs for geothermal systems. Guild utility companies often offer $150–$500 rebates for high-efficiency equipment or smart thermostats, and low-interest financing may be available through local banks or the TVA EnergyRight program.
What should the quoted cost of an HVAC replacement include?
A transparent proposal should list: equipment model numbers and efficiencies, labor, new thermostat, refrigerant line set or flush, electrical disconnect and whip, drain line, start-up and commissioning tests, permits, haul-away of old units, manufacturer warranty (typically 10 years parts, up to lifetime heat exchanger), and a labor warranty (1–10 years). Extras such as duct sealing, zoning dampers, smart vents, or indoor air quality add-ons should be priced separately so you can compare apples to apples.
Do I need to replace my ductwork when I replace my HVAC unit?
Not always, but ducts in many Guild homes leak 20–30 % of conditioned air or are undersized. Your contractor should inspect for leakage, insulation R-value, damage, and sizing. If static pressure is high, upgrading to larger or sealed rigid ducts will improve airflow and system longevity. Older duct board or flex that shows mold, crushed sections, or insulation decay should be replaced. Even if ducts stay, have them professionally sealed and insulated to at least R-8 for attic runs.
