FAQs
How can I tell whether my gas furnace or complete HVAC system really needs to be replaced?
Several warning signs point to replacement rather than another repair: (1) Age – most gas furnaces last about 15–20 years and central air conditioners 12–15 years. If yours is nearing or past that, the major components are approaching the end of their service life. (2) Rising utility bills – efficiency drops as heat exchangers, burners and compressor coils become worn or corroded. (3) Frequent or expensive repairs – needing service more than once a season or facing a single repair that exceeds 25–30 % of the cost of a new system indicates poor value. (4) Comfort issues – rooms that never reach set-point, excessive cycling, or humidity problems show the equipment is no longer matched to the home’s needs. (5) Safety concerns – cracked heat exchangers, persistent CO detector alarms, or the presence of rust/soot are immediate replacement triggers. Our Crab Orchard comfort advisor can inspect the system, run efficiency tests, and give you an honest “repair vs. replace” cost comparison so you can make an informed decision.
What size furnace or air-conditioning unit is right for a home in Crab Orchard’s climate?
Correct sizing is critical for efficiency, comfort and equipment life. We perform a Manual J load calculation that factors in square footage, insulation levels, window type and orientation, infiltration rates, number of occupants, and local design temperatures (about 17 °F winter and 90 °F summer for Crab Orchard). An average 1,800-sq-ft well-insulated home might need a 45–60 kBTU 2-stage gas furnace matched with a 2.5–3-ton air conditioner or heat pump, but numbers vary widely. Oversized units short-cycle, causing wear and humidity swings; undersized units run constantly and still can’t keep up. We measure, calculate and then recommend equipment that will operate in the ideal 70–100 % capacity range for most of the season, giving you steady temperatures, lower bills and quieter operation.
How long will the replacement take and will I be without heating or cooling during the process?
Most straightforward change-outs (furnace, coil and outdoor unit set on existing ductwork and electrical) are completed in one working day—typically 6–8 hours. If new duct runs, line-set relocation, or code upgrades are required, plan on 1½–2 days. You’ll be without heating or cooling only while the old equipment is disconnected and the new system is tied in—usually 2–4 hours. We schedule replacements so you’re never left overnight without conditioned air; in cold snaps we bring portable electric heaters to keep pipes from freezing, and in summer we start early to restore A/C before peak afternoon heat.
Are there any rebates or incentives for installing a high-efficiency gas furnace or A/C in Crab Orchard?
Yes. (1) Federal tax credits: Under the 25C program you can claim up to 30 % of project cost, capped at $2,000, for a qualifying high-efficiency furnace, air conditioner, or heat pump installed in 2023-2032. (2) Utility rebates: Many regional utilities that serve Crab Orchard—including electric cooperatives in the TVA EnergyRight® network—offer $150–$500 credits for ENERGY STAR® gas furnaces (95 % AFUE or higher) and high-SEER heat pumps. (3) Manufacturer promotions: Seasonal instant rebates or extended labor warranties can reduce cost another $300–$1,200. We file the paperwork for you and apply utility rebates as an instant discount on your invoice so you see the savings immediately.
What kind of warranty protection will I get with a new system from your company?
Our primary furnace line carries a Lifetime Limited Warranty on the heat exchanger and a 10-Year Limited Parts Warranty on everything else once the unit is registered (we handle registration for you). The matching air-conditioning or heat-pump condenser comes with a 10-Year Compressor and Parts Warranty. We add a 1-Year Labor Warranty at no extra charge, and you can upgrade to a 5- or 10-Year Labor Protection Plan that covers service calls, parts, and labor with no deductible. All warranties are backed by the manufacturer and serviced locally by our own NATE-certified technicians, so you never call an 800 number—you call Crab Orchard’s hometown HVAC team.
How much should I budget for a complete HVAC replacement and do you offer financing?
Pricing depends on capacity, efficiency rating, duct modifications and accessory items (smart thermostat, air cleaner, humidifier), but most full system replacements in Crab Orchard fall between $7,000 and $12,000 installed. High-efficiency variable-speed furnaces or 17+ SEER2 inverter heat pumps can raise that to $14,000–$16,000 but qualify for larger energy savings and incentives. To make the project affordable we offer several financing options through Synchrony and GoodLeap: 0 % interest for 12–18 months, or low-APR plans up to 72 months, with approvals often in under 10 minutes. We also accept major credit cards and can phase work (for example, replacing the furnace now and the A/C in spring) to fit within your budget.
