FAQs
How can I tell whether my older furnace or air conditioner should be repaired or completely replaced?
You should start considering replacement when your furnace or AC is more than 15–20 years old, requires frequent or costly repairs, makes unusual noises, or causes noticeably higher utility bills. In Winfield’s four-season climate, equipment that cannot reliably reach target temperatures or maintain comfort during extreme cold or humidity is a clear sign the system is losing efficiency. A professional load calculation and inspection can compare the remaining life of your current unit with the long-term savings of a modern high-efficiency system, helping you decide which option offers the better return on investment.
What size and type of HVAC system is usually recommended for homes in Winfield?
Homes in Winfield commonly need 60,000–100,000 BTU furnaces and 2–4-ton air conditioners or heat pumps, but proper sizing is never one-size-fits-all. Our technicians perform Manual J calculations that factor in square footage, insulation levels, window area, sun exposure, and air leakage to choose the exact capacity your house needs. Selecting the correct size is critical—oversized equipment short-cycles and wastes energy; undersized systems struggle in Illinois’ cold winters and humid summers. Depending on your goals, we may recommend single-stage, two-stage, or variable-speed furnaces and 14–20 SEER2 air conditioners or cold-climate heat pumps.
Are there energy rebates or tax incentives for upgrading my HVAC system in Winfield?
Yes. Residents served by ComEd and Nicor Gas can qualify for utility rebates—often $200–$600 for a high-efficiency gas furnace (95% AFUE or higher) and $400–$1,000 for a 16 SEER2+ air conditioner or heat pump. Federally, the Inflation Reduction Act’s 25C tax credit allows up to $600 back on a qualifying furnace and up to $2,000 on a high-efficiency heat pump or heat-pump water heater. Additional state or municipal incentives may apply for income-qualified households. We handle all paperwork and will confirm current promotions at the time of your estimate.
How long does a furnace and AC replacement take, and will I be without heat or cooling during the process?
Most standard change-outs can be completed in a single day (6–10 hours). We remove the old units, modify or replace transition fittings, set the new equipment, reconnect gas/electrical lines, pressure test the refrigerant circuit, and commission the system. For projects involving ductwork revisions, new thermostats, or indoor air-quality add-ons, work may extend into a second day. You’ll lose heating/cooling only while the old system is disconnected; we schedule installs to minimize downtime and can provide temporary heaters or loaner window ACs during extreme weather if needed.
What does it typically cost to replace both a furnace and central air system in Winfield, and what factors affect price?
A complete high-efficiency furnace and AC replacement in a typical 2,000 sq ft Winfield home ranges from about $8,000 to $14,000 after rebates. Price variables include equipment efficiency (80% vs. 96% AFUE, 14 vs. 18 SEER2), brand, single-stage vs. variable-speed technologies, duct modifications, line-set replacement, code upgrades (flue liners, electrical circuits, condensate pumps), and any add-ons such as humidifiers, air cleaners, or smart thermostats. We provide multiple written options so you can balance upfront cost with long-term energy savings.
How will a new HVAC system improve comfort, indoor air quality, and energy bills?
Modern furnaces feature multispeed or modulating gas valves and ECM blower motors that maintain more consistent temperatures and quieter operation. High-SEER2 air conditioners and heat pumps use advanced scroll compressors and better coils to dehumidify efficiently, making summer air feel cooler at higher thermostat settings. Optional whole-home air cleaners and humidifiers integrate easily with new equipment, removing up to 99% of airborne particles and keeping humidity in the ideal 30–50% range. Collectively, today’s systems can lower heating costs by 20–40% and cooling costs by 15–30% compared to models installed two decades ago, paying back the upgrade through smaller utility bills while keeping your Winfield home healthier and more comfortable year-round.
