Furnace Service in St. Louis, MO

When Should You Repair or Replace a Furnace?

Age matters, but it isn’t the only factor. We also consider the equipment’s condition, repair history, heating consistency, efficiency, and current operating problems before discussing your options.

Signs that may warrant a replacement evaluation include:

• Frequent service calls or recurring repairs
• Unusual noises or persistent odors
• Uneven temperatures between rooms
• Increasing energy bills without a clear explanation
• Declining indoor air quality
• A system approaching 15 to 20 years old

How AFUE Ratings Measure Furnace Efficiency

Annual Fuel Utilization Efficiency (AFUE) measures how much fuel a furnace converts into usable heat over a typical year. Standard-efficiency furnaces generally rate around 80% to 83% AFUE, while high-efficiency models commonly range from 90% to 98.5%. Some older furnaces operate between 56% and 70% AFUE, using considerably more fuel to produce the same amount of heat.

Replacement also provides an opportunity to consider quieter equipment, updated heating technology, and smart thermostat compatibility. Another option is a dual-fuel heating system, which pairs a heat pump with a furnace. The heat pump handles milder weather, and the furnace supplies heat when temperatures fall.

Furnace Maintenance & Carbon Monoxide Safety

Carbon monoxide is a colorless, odorless gas produced during combustion. A properly operating gas or oil furnace directs combustion gases outdoors through its exhaust system. Electric furnaces don’t produce these byproducts.

The heat exchanger is a metal barrier that separates combustion gases from the air circulating through the building. If it cracks, or if the exhaust vent becomes clogged, carbon monoxide can enter the indoor air. A professional inspection can uncover heat exchanger damage, venting concerns, and other problems before they become more serious.

Regular maintenance also promotes efficient operation and reduces the likelihood of unexpected repairs during heavy use. Our routine process covers thermostat settings, mechanical parts, electrical components, and filters.
