FAQs
What is a dual-fuel heating and cooling system, and how does it work?
A dual-fuel system combines an electric heat pump with a gas furnace. In mild weather the heat pump provides efficient heating and cooling, keeping energy costs low. When outdoor temperatures drop below a preset balance point—typically around 35–40°F—the system automatically switches to the gas furnace for stronger, more economical heat. This automatic changeover gives homeowners in McDonald the best efficiency and comfort in every season.
What warning signs indicate my dual-fuel system needs repair?
Common red flags include rooms not reaching the set temperature, short-cycling (frequent on/off), higher-than-normal utility bills, uneven airflow, unusual noises (grinding, squealing, or rattling), a constant yellow furnace flame, or a heat pump that ices up and won’t defrost. If you notice any of these issues, schedule service promptly to avoid further damage and energy waste.
How fast can you respond to an emergency heat repair call in McDonald?
We offer 24/7 emergency service throughout McDonald and surrounding Washington County communities. Calls received before 5 p.m. typically receive same-day service; after-hours and weekend calls are dispatched within two hours. Our fully stocked service vehicles carry the most common heat pump and furnace parts, so most repairs are completed on the first visit.
Will repairing my dual-fuel system really lower my energy bills?
Yes. A properly functioning dual-fuel system seamlessly switches between the heat pump and furnace at the correct outdoor temperature. When the switch point is off or a component is failing, the unit may run on the less-efficient stage longer than necessary, driving up costs. Restoring correct refrigerant charge, airflow, sensors, and furnace calibration can reduce monthly heating expenses by 10–30 % and prevent premature equipment wear.
Are your technicians qualified to service both the heat pump and the gas furnace components?
Absolutely. Our NATE-certified technicians receive factory training on Carrier, Trane, Lennox, Rheem, and other major brands. They hold EPA Section 608 certification for refrigerant handling and state HVAC licenses for gas-fired equipment. That means they can diagnose electrical, refrigerant, and combustion problems in a single visit and ensure all safety codes are met.
How much does a dual-fuel system repair cost, and do you offer maintenance plans?
Most minor repairs (capacitors, igniters, flame sensors) range from $175–$350. Compressor or inducer motor replacements can range from $800–$1,700. After diagnosing, we present flat-rate pricing upfront so you know the exact cost before work begins. We also offer ComfortGuard Maintenance Plans starting at $19.95 per month, which include two seasonal tune-ups, priority scheduling, 15 % repair discounts, and a one-year labor warranty on all covered repairs.
