FAQs
What qualifies as an air-conditioning emergency in Karns?
Any situation that threatens your family’s safety, health, or property should be treated as an emergency. Examples include total system failure during extreme heat, refrigerant leaks, electrical burning smells, smoke coming from the air handler, frozen coils that stop airflow, or a clogged condensate drain causing water to overflow and damage ceilings or floors. If you are unsure, call us—our dispatcher can quickly confirm whether immediate service is needed.
How fast can you arrive for an emergency AC repair in Karns?
Because we have on-call technicians stationed throughout Knox County, our average on-site response time in Karns is 60–90 minutes after your call is dispatched. During severe weather or city-wide outages, arrival may take longer, but we always give you an accurate ETA, keep you updated by text, and arrive with a fully stocked service vehicle so most repairs are completed in a single visit.
Will I be charged extra for after-hours or weekend emergency service?
We never inflate parts prices, and our diagnostic fee stays the same 24/7. An after-hours service premium does apply to cover overtime labor, but you will know the total repair cost up front before any work begins. We also waive the overtime fee for customers enrolled in our ComfortGuard maintenance plan.
What should I do while waiting for the technician to arrive?
1) Turn the thermostat to OFF to prevent further damage. 2) Check your breaker panel to make sure the AC breaker hasn’t tripped. 3) Remove pets from the service area and ensure the outdoor unit is accessible. 4) If you see water leaking, place towels or a shallow pan under the unit to limit damage. 5) Keep windows closed to avoid excess humidity; use portable fans for temporary relief. Never attempt to open the sealed refrigerant lines or electrical compartment yourself.
Do you service all brands and warranty types?
Yes. Our NATE-certified technicians are factory-trained to diagnose and repair every major brand, including Trane, Carrier, Lennox, Goodman, Rheem, American Standard, and Daikin. We honor most manufacturer parts warranties and will file the paperwork for you. If your system is still under a labor warranty from another contractor, we can provide documentation so you can request reimbursement.
How can I prevent future AC emergencies?
Regular maintenance is the #1 defense against unexpected breakdowns. We recommend two precision tune-ups per year: once in spring for cooling and once in fall for heating. During these visits we clean coils, test capacitors, tighten electrical connections, check refrigerant charge, clear the condensate line, and verify airflow. Enrolling in our ComfortGuard plan reduces energy bills by up to 15%, extends equipment life, and gives you priority service with no overtime rates on future emergencies.
