FAQs
What is a dual-fuel HVAC system and how does it work?
A dual-fuel system combines an electric heat pump with a high-efficiency gas furnace. In mild weather the heat pump provides heating and cooling, which is typically cheaper and more energy-efficient than running a furnace. When outdoor temperatures fall below a pre-set balance point (usually between 35 °F and 40 °F in Philadelphia), the system automatically switches to the gas furnace for stronger, more cost-effective heat. A smart control board chooses the fuel source that delivers the best comfort at the lowest operating cost.
Why is dual-fuel a good replacement choice for Philadelphia homes?
Philadelphia experiences hot, humid summers and cold winters with frequent temperature swings. A dual-fuel setup matches this climate perfectly: the heat pump efficiently cools in summer and heats during spring and fall, while the gas furnace handles bitter-cold snaps without the high electric bills that all-electric heat pumps can incur. Homeowners typically see lower annual energy costs, fewer greenhouse-gas emissions, and more consistent indoor comfort compared with a traditional furnace-and-AC pair.
How can I tell if my current HVAC equipment should be replaced instead of repaired?
Consider replacement when: 1) your furnace or AC is 12–15 years old, 2) repair estimates exceed 30 % of the cost of a new system, 3) utility bills keep climbing despite regular maintenance, 4) you struggle with uneven temperatures or excessive noise, or 5) your equipment still uses R-22 refrigerant, which is no longer produced. A professional load calculation and energy audit from our team will confirm whether a dual-fuel upgrade will improve efficiency and comfort enough to justify the investment.
How much does a dual-fuel replacement cost in the Philadelphia area, and what is the payback period?
Installed prices generally range from $11,000 to $18,000, depending on home size, ductwork condition, thermostat options, and efficiency ratings (SEER2 and AFUE). Because the heat pump handles a large share of the heating load, many homeowners save 20 – 40 % on annual energy costs. With current electricity and natural-gas rates in southeastern Pennsylvania, typical payback runs 5–8 years. Higher-efficiency models or generous incentive programs can shorten that period even further.
Are there rebates, tax credits, or utility incentives available for dual-fuel installations?
Yes. PECO currently offers rebates up to $400 for qualifying high-efficiency heat pumps and $300 for ENERGY STAR gas furnaces. Federal tax credits under the Inflation Reduction Act provide up to $2,000 for heat pumps rated ≥15.2 SEER2/11.7 EER2/7.8 HSPF2, plus up to $600 for qualifying furnaces. Income-based rebates from the forthcoming HOMES and High-Efficiency Electric Home programs may cover an even larger portion of the project cost. We handle all paperwork to ensure you receive every available incentive.
What is the installation timeline and what should I expect during a replacement?
Most dual-fuel replacements take 1–2 days. Day 1: Our crew removes old indoor and outdoor units, inspects and seals ductwork, installs the new heat pump condenser and gas furnace, and connects refrigerant and gas lines. Day 2: We set up the communicating thermostat, pressure-test and evacuate the refrigerant circuit, charge the system, and perform a full safety and performance check. You’ll have heat or cooling available each evening. We register equipment warranties, file rebate forms, and schedule a post-installation walk-through to explain maintenance requirements and answer questions.
