FAQs
What exactly is a dual-fuel HVAC system and how does it work?
A dual-fuel system pairs an electric heat pump with a high-efficiency gas furnace. In cooling mode, the heat pump operates just like a conventional central air conditioner. In heating mode, the heat pump handles mild outdoor temperatures (usually down to 35–40 °F), because it can heat very efficiently using electricity. When the temperature dips lower and the heat pump’s efficiency drops, an integrated control board automatically switches over to the gas furnace for stronger, faster heat. The result is year-round comfort with the most economical energy source for every weather condition.
Why is a dual-fuel replacement a good choice for homes in Pelham?
Pelham experiences muggy summers in the 90s and winter lows that can fall into the 20s—conditions that are perfect for dual-fuel. The heat pump keeps summer electric bills low and provides inexpensive heat during our many mild winter days, while the gas furnace offers reliable warmth during cold snaps. This balance maximizes efficiency, reduces overall utility costs, and minimizes greenhouse-gas emissions compared with running a gas furnace all season.
Will my existing ductwork, thermostat, and electrical service work with a new dual-fuel unit?
In many cases, yes. Most Pelham homes with a standard split HVAC system already have supply/return ducts sized for similar airflow, so only minor sealing or resizing is required. Your current 24-volt thermostat wiring can usually be re-purposed, but upgrading to a Wi-Fi dual-fuel-compatible thermostat lets you fine-tune changeover temperatures. A 240-volt, 30- to 60-amp circuit is needed for the heat-pump condenser; if you already have central AC, that circuit often meets code. During our in-home evaluation we inspect the ductwork, gas line, flue venting, and breaker panel to confirm compatibility and quote any necessary upgrades up front.
How much does a dual-fuel replacement cost and are there local rebates?
Turn-key pricing in Pelham typically ranges from $9,500 to $14,500, depending on capacity (2-5 tons), SEER2/HSPF ratings, furnace AFUE, and any duct or electrical modifications. Alabama Power customers can qualify for rebates of $150–$400 on high-efficiency heat pumps, and Spire Gas often offers $300–$600 back on 95%+ AFUE furnaces. Federal tax credits under the Inflation Reduction Act add up to $2,000 for qualifying heat pumps. We handle all rebate paperwork and apply the credits to your final invoice whenever possible.
How much can I expect to save on energy bills compared with my current system?
Savings vary with usage habits and fuel prices, but most Pelham homeowners moving from a 10–13 SEER AC plus 80% gas furnace to a 16–18 SEER2 heat pump and 96% furnace see 25–40 % lower annual heating/cooling costs. The heat pump provides 2–3 units of heat for every unit of electricity consumed in mild weather, while the high-efficiency furnace cuts gas consumption by 15–20 %. Payback on the incremental cost of dual-fuel versus conventional replacement is often 4–6 years, and faster if your current propane or natural-gas rates are high.
What is the installation timeline and what should I expect during the replacement process?
After your free in-home consultation and signed proposal, we typically schedule installations within 5–7 business days. Most dual-fuel replacements take one full day: 1) safely evacuate and remove the old condenser, evaporator coil, and furnace; 2) set the new heat pump condenser on a composite pad; 3) install the matching indoor coil and gas furnace; 4) connect refrigerant, gas, condensate, and electrical lines; 5) pressure-test, evacuate, and charge the system with R-410A or R-32 refrigerant; 6) program and test the thermostat for automatic changeover. Your home will have heating or cooling restored before we leave, and you’ll receive a walkthrough on filter changes, thermostat operation, and maintenance schedules.
