If you hear a buzzing or humming sound from your outdoor unit but the fan is not running, this usually points to a failed dual run capacitor or a bad contactor. The noise is the electrical current trying to start the motor, but it lacks the boost it needs. Turn your system off at the thermostat immediately to prevent permanently burning out the compressor motor. Then call us for 24/7 emergency service! Our highly qualified technicians carry these parts on their trucks and can typically fix this in a timely manner. Plus, we service all brands!

This is a common issue during the summer. It’s typically caused by a dirty air filter blocking airflow, low refrigerant levels (indicating a leak), or a dirty outdoor condenser coil. 24/7 emergency service is available, and our technicians can quickly diagnose the root cause and restore your cold air.

If your furnace is over 12-15 years old, requires frequent repairs, or if the cost to repair it is more than 50% of the cost of a new system, a new furnace and installation is usually the most cost-effective option. We provide honest assessments and won’t push for a replacement if a simple repair makes sense. However, if you decide it is time to replace, we offer free estimates on new equipment.

For most homes in Knox County, we recommend changing standard 1-inch filters every 30 to 90 days. If you have pets, allergies, or run your system constantly during extreme weather, you should check and replace it closer to the 30-day mark.

A sudden spike in your heating or cooling costs usually means your HVAC system is working harder than it should. This can be caused by aging equipment, leaking ductwork, a failing motor, compressor, or simply a lack of seasonal maintenance. Call us today to schedule an appointment, or for 24/7 emergency service if your issue needs to be fixed quickly.
