Call Charles Stone if you notice any of the following warning signs. We’ll investigate and determine whether you need a furnace repair.
- Unusual odors
- Difficulty starting the system
- Abnormal or loud noises
- Pilot light malfunctions

Sometimes, furnace issues aren’t subtle. A complete furnace shutdown calls for emergency heating repair ASAP. Charles Stone provides 24/7 emergency HVAC repair in the Upper Cumberland, so you’re never left out in the cold.
Our trained HVAC technicians can repair any brand or model of heater, and we keep our trucks stocked with common parts to handle most repairs on-site. If a furnace can’t be fixed or replacement is more cost-effective, we’ll provide a transparent review of your best options.
Heating Replacement & Installation Services
A breakdown during freezing temperatures is stressful and inconvenient, often leaving you scrambling for repairs or a place to stay. The best way to avoid that hassle is to schedule a professional maintenance check before the season starts.
Our technicians will inspect your system, let you know whether it’s winter-ready, and be upfront if a new furnace installation is the smart choice. These are the signs you may need a new heater:
- Rising energy bills
- Unusual noises (rattling, banging, constant clicking)
- Uneven or inadequate heating
- Persistent burning odors
- Furnace age of 15 to 20+ years
- Frequent or costly repairs
If any of these apply, it’s time to have your system evaluated.
