FAQs
What situations are considered a heating emergency in Jonesborough, and how quickly can you arrive?
A heating emergency is any situation where your furnace, heat pump, or boiler will not run, is blowing cold air, is emitting a burning or gas-like odor, or is triggering safety devices such as carbon-monoxide alarms—especially when outside temperatures are near or below freezing. Because Jonesborough winters can dip into the 20s, loss of heat can quickly become a health and safety risk. Our on-call team is staffed 24/7 and typically reaches any address in the Jonesborough area within 60–90 minutes of your call.
Are your emergency service technicians qualified to work on all brands and fuel types?
Yes. Every technician who answers an emergency call is Tennessee HVAC-licensed, NATE-certified, and EPA-certified for refrigerants. We stock common replacement parts for all major brands—Trane, Carrier, Lennox, Goodman, Rheem, Bryant, York, and more—and handle gas, electric, oil, and dual-fuel heat pumps. If specialty parts are required, we can place rush orders through our regional suppliers to minimize downtime.
What should I do while waiting for the technician to arrive?
1) Turn the system off at the thermostat or breaker to prevent further damage. 2) If you smell gas, evacuate everyone, shut off the gas at the main valve if possible, and call 911 before calling us. 3) Keep doors and windows closed to retain residual heat; gather in the warmest room and use space heaters or extra blankets if safe to do so. 4) Clear a path to the indoor unit and the outdoor heat-pump cabinet so our technician can work quickly when they arrive.
How much does after-hours or weekend emergency service cost?
We charge a flat, upfront emergency diagnostic fee that covers travel and the first 30 minutes of troubleshooting, regardless of the day or hour. Once the problem is identified, you receive a written estimate for parts and labor. There are no hidden overtime multipliers—if you approve the quote, we perform the repair immediately; if you decline, you owe only the diagnostic fee.
Can you repair both gas furnaces and heat pumps that are common in Jonesborough homes?
Absolutely. Many Jonesborough homes use high-efficiency gas furnaces, while others rely on air-source heat pumps or dual-fuel systems. Our technicians carry combustion analyzers, refrigerant gauges, defrost controls, ignitors, flame sensors, blower motors, and other parts specific to both furnace and heat-pump technology—allowing most repairs to be completed on the first visit.
What if my heating system is beyond repair or the cost is too high?
If the heat exchanger is cracked, the compressor has failed, or the repair cost approaches 40–50% of the price of a new unit, we may recommend replacement for long-term safety and efficiency. We will provide multiple replacement options—including ENERGY STAR-rated furnaces and variable-speed heat pumps—along with financing plans, manufacturer rebates, and any available TVA or federal tax credits. We can usually install a new system within 24-48 hours to restore reliable heat.
