Bigger is not better when it comes to furnaces. An oversized unit short-cycles, overshoots the thermostat, and wears out early, while a correctly sized furnace runs longer and more quietly and costs less to operate. So Bethlehem HVAC starts every replacement in Bethlehem with a load calculation, not the number on the old nameplate. From there, the choices come into focus: 80 percent AFUE or a condensing furnace in the mid-90s, single-stage, two-stage, or modulating burners, and a basic PSC blower or a variable-speed ECM motor that saves electricity and smooths out temperature swings. The right combination depends on your home, your ducts, and how long your heating season lasts, and you will be living with it for the next twenty years.
Most of our service calls are for Furnace Repair. Start there if your system isn't running right.
Warning Signs for Furnace Installation
Spotting the early warning signs lets you act before the problem gets expensive. Watch for these telltale signs:
- Rust, soot, or loud ignition that returns even after repairs
- Your current furnace is past the fifteen-to-twenty-year mark
- Short cycling, big temperature swings, or rooms the furnace never reaches
- A cracked heat exchanger has been found, ending the repair conversation
- A blower so noisy you have to raise your voice when it runs
- Rising energy bills and a home that still feels chilly
- Repair bills arriving more often and getting bigger each season
- A new air conditioner or heat pump is going in and the old furnace cannot keep up
Early Action Saves Money
What seems like a minor issue today can take out a compressor or heat exchanger tomorrow. At the first hint of a problem, call (610) 788-0052 for a fast inspection.
