FAQs

What types of HVAC repair services do you provide in Cosby?

We handle comprehensive repairs for gas and electric furnaces, heat pumps, central air-conditioning units, mini-splits, ventilation fans, air handlers, ductwork, humidifiers, de-humidifiers, and air purification systems. Whether the issue is a worn-out blower motor, a frozen evaporator coil, leaky ducts, or malfunctioning smart thermostat, our certified technicians can diagnose and restore the system to factory specifications.

How can I tell if my heating or cooling system needs repair rather than replacement?

Warning signs include uneven temperatures, short cycling, spikes in utility bills, unusual noises or odors, weak airflow, and persistent humidity problems. If your unit is under 12–15 years old, most problems (bad capacitors, clogged filters, refrigerant leaks, etc.) can usually be repaired cost-effectively. We always perform a cost-benefit analysis that factors in age, efficiency, warranty status, and repair frequency so you can decide with clear numbers whether repair or replacement is the smarter investment.

Do you offer 24/7 emergency repairs, and how quickly can you reach my home in Cosby?

Yes. Our dispatch center is staffed around the clock, 365 days a year. For homes in Cosby and the surrounding Sevier/Cocke County area, a technician is typically on-site within 2–4 hours of your call—often sooner during extreme weather events. Each service truck carries common OEM parts, allowing us to complete most emergency repairs in a single visit.

How does poor ventilation affect indoor air quality and my family’s health?

Insufficient ventilation traps moisture, allergens, and airborne pollutants, leading to mold growth, lingering odors, aggravated asthma, and an increased spread of viruses. High CO₂ levels can also cause fatigue and headaches. Properly balanced mechanical ventilation—combined with filtration and humidity control—removes stale indoor air and continuously supplies fresh, conditioned air, creating a healthier and more comfortable living environment.

What steps can I take between service visits to improve ventilation and air quality?

Replace or clean HVAC filters every 1–3 months, keep supply and return vents unobstructed, run bathroom and kitchen exhaust fans during and after use, and use your system’s "fan-on" setting for 15–20 minutes a few times a day to circulate and filter air. Consider adding stand-alone HEPA or UV-air purifiers in high-traffic rooms, and maintain indoor humidity between 30–50 % with a whole-home humidifier or de-humidifier as needed.

Are your repairs covered by warranty, and do you work with manufacturers’ warranties as well?

All repair labor is backed by a 1-year workmanship warranty, and new replacement parts carry the manufacturer’s parts warranty, typically 1–10 years depending on the component. If your equipment is still under the original equipment manufacturer (OEM) warranty, we handle all paperwork, verify coverage, and process claims so you only pay for out-of-warranty items, if any. Extended protection plans are also available for added peace of mind.
