FAQ
Frequently Asked Questions
Practical answers to common heating questions from homeowners across Knoxville.
What thermostat setting is best for comfort and savings in winter
A good starting point is 68°F when you are home and awake, then a few degrees lower while you sleep or are away. Smart thermostats can automate schedules and help you reduce energy use without sacrificing comfort.
Why does my heater smell when I turn it on the first time each season
A brief dusty smell is common when the system first runs after months off. It usually clears quickly. If the odor is strong, persists, or smells musty or burnt, it could indicate a dirty filter, airflow restriction, or a component overheating. That is a good time to schedule an inspection.
My furnace is running but the house still feels cold. What could be wrong
Common causes include a clogged filter, airflow issues, duct leakage, incorrect thermostat settings, or a failing component like a blower motor or flame sensor. We test the full system and identify the root cause so the fix actually lasts.
Are all-electric heat pumps reliable during colder weather
Yes. Modern heat pumps are far more capable than older electric systems and can perform well in our region. The right answer depends on your home insulation, ductwork, and comfort goals. We evaluate your setup and recommend the best configuration for dependable heat.
How often should I schedule furnace maintenance
Once per year is the typical recommendation, ideally in fall before peak use. Maintenance improves safety, supports efficiency, and reduces surprise breakdowns during cold snaps.
