FAQs

What are the most common reasons my heating system in New Tazewell is making banging or knocking noises?

Banging or knocking usually points to expanding and contracting ductwork, delayed gas ignition in a furnace, or a loose blower wheel. Metal ducts in particular can pop as temperatures change, while gas-fired units may accumulate debris on the burner that causes a small explosion when the gas finally lights. A loose blower wheel thumps each time it rotates. Our technicians start by inspecting the burner assembly, blower, and duct supports to pinpoint and correct the source.

Is it safe to keep running my HVAC system if I hear squealing, screeching, or grinding sounds?

A brief squeal at startup can be normal, but continuous squealing, screeching, or grinding means you should shut the system off and call for service. These noises often indicate a worn blower motor bearing, slipping belt, or failing inducer motor, all of which can overheat and seize. Continuing to run the equipment may cause a total motor failure or even damage the control board, turning a minor repair into a major—and more expensive—replacement.

How quickly can you send a heat repair technician to my home or business in New Tazewell?

We provide same-day service for no-heat or loud-noise calls received before 3 p.m. and 24-hour emergency dispatch for after-hours cases. Because our service hub is located just off U.S. 25E, we can reach most New Tazewell addresses within 60-90 minutes. During peak heating season we reserve extra on-call technicians specifically for urgent noise-related repairs, so you’re not left shivering or worrying about potential safety hazards.

Can strange noises really raise my energy bills?

Yes. A loose or failing component forces the system to work harder. For example, a blower motor with worn bearings draws more amperage, while a slipping belt reduces airflow and makes the furnace burn longer to satisfy the thermostat. Even minor duct leaks that create whistling sounds waste conditioned air. Addressing the noise promptly improves efficiency, lowers monthly utility costs, and often prevents larger breakdowns.

Are repairs for noisy furnaces or heat pumps covered under warranty?

Most manufacturers’ parts warranties (usually 5–10 years) cover defects such as premature motor or blower wheel failure, but they don’t cover labor after the first year. If your equipment is still under warranty, we will process the parts claim on your behalf; you only pay for diagnostic and labor charges. For out-of-warranty systems, we offer flat-rate pricing and financing options for larger repairs. Routine maintenance is the best way to keep warranties valid and catch issues before they become noisy problems.

What diagnostic steps do you take to determine the source of a strange noise in my HVAC system?

Our technicians follow a five-point checklist: 1) Listen to the unit during startup, operation, and shutdown to isolate the timing and frequency of the noise. 2) Inspect blower assembly, belts, and pulleys for looseness or wear. 3) Test motor amperage and bearings for signs of electrical or mechanical stress. 4) Examine burners, heat exchanger, and ignition system for delayed ignition or metal expansion noises. 5) Check ductwork connections, dampers, and insulation for vibration or pressure imbalances. We then explain the findings, show you any worn parts, and present repair options before starting work.
