Customer Questions About Home Heating in Knoxville, TN

At Pol’s Heating and Cooling, LLC, we’ve heard every concern from Knoxville, TN, homeowners about home heating. We’re here to turn up the heat on confusion with straightforward answers that keep your family comfortable in winter. Here are some answers to the most common questions we receive about home heating:

Why Does My Furnace Make Strange Noises During Operation?

Furnaces communicate through sound, and understanding their language prevents minor issues from becoming major headaches. That banging, whistling or grinding you’re hearing isn’t normal background noise; it’s your system signaling specific problems.

Banging often indicates delayed ignition, where gas builds up before igniting in a small explosion. Whistling suggests restricted airflow, often due to dirty filters or closed vents. Grinding points on worn bearings in the blower motor, requiring immediate attention before complete failure.

How Often Should I Replace My Air Filter?

Air filter replacement stands as the simplest yet most impactful maintenance task homeowners can perform. Standard one-inch filters need replacement every 30 days during heating season, while thicker four-inch filters last approximately three months. Homes with pets, allergies or above-average dust require more frequent changes.

A clogged filter forces your furnace to work harder, increasing energy consumption by up to 15%. This seemingly minor neglect can lead to higher utility bills and unnecessary wear on critical components. The investment costs only a few dollars but delivers substantial returns in efficiency and equipment longevity.

What Temperature Should I Set My Thermostat For?

The eternal thermostat debate has a scientific answer that balances comfort with efficiency. The Department of Energy recommends 68°F while you’re home and awake, and 62°F during sleep or when away. Each degree below 70°F saves approximately 3% on heating costs, a significant reduction over an entire season.

Programmable or smart thermostats automate these adjustments, eliminating the temptation to crank up the heat when you’re feeling chilly. Knoxville’s temperature fluctuations make these devices particularly valuable, as they adapt to our unpredictable weather patterns without constant manual intervention.

When Should I Schedule Professional Furnace Maintenance?

Timing matters tremendously with furnace maintenance, and waiting until problems arise costs considerably more than preventive care. Schedule your annual inspection before heating season begins, ideally in early fall. This proactive approach ensures your system performs optimally when you need it most. Professional maintenance includes comprehensive checks that homeowners cannot safely or effectively perform.

Why Are Some Rooms Colder Than Others?

Uneven heating frustrates homeowners and signals underlying system imbalances. Multiple factors contribute to temperature inconsistencies throughout your home.

Inadequate insulation allows heat to escape faster in certain areas, particularly in older Knoxville, TN, homes built before modern energy codes. Blocked or closed vents restrict airflow to specific rooms. Ductwork leaks can lose up to 30% of heated air before it reaches the intended spaces. Improperly sized HVAC systems struggle to evenly distribute conditioned air. A professional assessment identifies the root causes and implements targeted solutions rather than simply running your system harder.

How Long Should My Furnace in Knoxville, TN Last?

A well-maintained gas furnace typically operates efficiently for 15 to 20 years in our climate. Regular professional maintenance, prompt repairs and quality installation significantly influence longevity. Systems approaching 15 years should be evaluated for efficiency, as newer heat pump models offer substantial energy savings that offset replacement costs within a few years.

Why Is My Furnace Turning Off and On Frequently?

Short cycling indicates your furnace turns on and off too frequently, never completing full heating cycles. This behavior stems from oversized equipment, malfunctioning thermostats, clogged filters or faulty flame sensors. Short cycling increases component wear, raises energy bills and fails to heat your home adequately. Professional diagnosis identifies the specific cause and implements appropriate corrections.
