FAQs
How quickly can you respond to an AC or heating emergency in Maynardville?
Because we have technicians based in Union County, we’re usually able to arrive anywhere in Maynardville within 60–90 minutes of your call—often sooner during normal business hours. Our trucks are stocked with the most commonly needed parts, which means we can complete most repairs on the first visit and restore your comfort without delay.
What are the most common AC problems you see in the Maynardville area?
The issues we see most often include low refrigerant levels due to small leaks, dirty condenser coils from pollen and mowing debris, clogged condensate drains that back up in our humid summers, and capacitor or contactor failures that prevent the outdoor unit from starting. All of these problems can usually be diagnosed and repaired the same day, provided the system hasn’t suffered severe compressor damage.
How much does a typical air-conditioning repair cost?
Repair costs vary according to the part that has failed, the age and brand of the equipment, and whether the service call occurs after hours. In Maynardville our average repair ticket ranges from $150–$500. Simple fixes like a failed capacitor or thermostat replacement are at the lower end, while refrigerant leak repairs, blower motor replacements, or control board failures are at the higher end. We always provide a written, flat-rate quote before any work begins, so you’ll never be surprised by the final bill.
Is it better to repair or replace an older HVAC system?
We generally recommend replacement when (1) the unit is more than 12–15 years old, (2) major components such as the compressor or heat exchanger have failed, or (3) projected repair costs exceed 30–40 % of the price of a new, higher-efficiency system. Modern heat pumps and air conditioners can be up to 50 % more efficient than units installed in the early 2000s, so replacing an aging system can lower your monthly energy bills while providing more reliable comfort. However, if your system is less than 10 years old and the repair is minor, fixing it is often the most cost-effective option.
How often should I schedule maintenance for my HVAC system?
Both the U.S. Department of Energy and equipment manufacturers recommend professional maintenance twice a year—once in the spring for cooling equipment and once in the fall for heating. During a tune-up we clean the coils, check refrigerant charge, inspect electrical components, test safety controls, and calibrate thermostats. Regular maintenance can reduce breakdowns by up to 95 % and may keep your factory warranty valid.
Are your technicians licensed and insured to work in Tennessee?
Yes. All of our lead technicians hold Tennessee HVAC Contractor or Restricted HVAC licenses, carry EPA Section 608 certification for refrigerant handling, and undergo annual background checks. The company is fully insured, including general liability and workers’ compensation coverage, so you can feel confident inviting us into your Maynardville home or business.
