Same-Day HVAC Service in Knoxville, TN

An HVAC diagnostic visit from Aire Serv of Knoxville costs $99 during regular business hours, and that fee is waived when you have us complete the repair. After your technician finds the problem, you receive upfront pricing by the job, not the hour, so you know the full cost before any work begins.

Yes, HVAC service outside regular business hours includes an additional fee: $129 for non-holiday evenings and weekends, and $229 on holidays. These after-hours fees are not waived with a completed repair. Emergency HVAC service is available during these times because a failed furnace on a holiday or a dead AC on a Saturday can't always wait until Monday.

Repair usually makes sense when your HVAC system is less than 10 to 15 years old and the problem is isolated, while replacement is often the better value for older systems that need frequent repairs or drive up energy bills. Our technicians give you upfront pricing for both options. If HVAC replacement is the right call, we provide a free in-home estimate, since we don't quote replacements over the phone, and financing is available.

Aire Serv of Knoxville recommends HVAC maintenance twice a year: in spring for your air conditioner and in fall for your furnace or heat pump. East Tennessee's humid summers and cold winter nights keep HVAC systems running for much of the year, and heat pumps work in both seasons. Seasonal tune-ups help catch worn parts early, protect efficiency, and lower the chance of a breakdown during peak demand.
