Before you call anyone
An HVAC emergency is defined by the people in the house, not by the equipment. A failed air conditioner in a mild May is an inconvenience. The same failure in August, in a home with an infant or an elderly resident, is a medical risk. What follows is how to tell the difference, and what to do in the hour before someone arrives.
What this looks like in Hendersonville
Homes near Old Hickory Lake fight humidity as much as heat. An air conditioner that cools to setpoint but leaves the house feeling clammy is usually short-cycling — oversized for the load — and the fix is rarely a new unit.
- Housing stock
- 1970s–80s lakeside construction along Old Hickory Lake alongside newer subdivisions inland, with a meaningful share of homes on original ductwork.
- Local conditions
- The December 2023 tornado outbreak caused significant damage in Sumner County, and lakeside humidity accelerates everything moisture touches.
- Permits issued by
- City of Hendersonville Codes Department
- Areas we cover
- Indian Lake, Sanders Ferry, Walton Ferry, Station Camp, Old Hickory Lake and the rest of Sumner County.
On the ground in Hendersonville
Half the emergency calls we get from Hendersonville aren't about heat or cold at all — they're about houses that feel wrong. A lot of the lakeside stock around Indian Lake and Old Hickory Lake is 1970s and 80s construction, original ductwork, sized for a different climate reality than what Old Hickory Lake humidity throws at it now. That ductwork leaks conditioned air into crawlspaces and attics, and the moisture problem gets worse every summer it's ignored.
If your AC hits setpoint but the house still feels clammy, that's usually not a broken unit — it's an oversized one short-cycling, cooling the air fast without ever running long enough to pull the humidity out. Homeowners near the lake replace a perfectly good compressor for this all the time. The actual fix is usually runtime and dehumidification control, not a new system.
We also see a spike in emergency calls tied to storm damage — the December 2023 tornado outbreak knocked out disconnects, condensers, and whole systems across Sumner County, and homes in Station Camp and Sanders Ferry are still dealing with equipment that was patched instead of properly replaced. This line covers no-heat, no-cool, burning smells, CO alarms, and water coming through the ceiling below an air handler — answered live, any hour.
Signs you are looking at this problem
- No cooling with indoor temperatures climbing past the mid-80s
- No heat with outdoor temperatures below freezing
- Burning smell, smoke, or visible scorching at the equipment or disconnect
- A carbon monoxide alarm sounding

- A breaker that trips again immediately after reset
How urgent is it?
Vulnerable occupants and an indoor temperature that is still climbing.
Electrical burning smell or repeated breaker trips — stop resetting it.
Uncomfortable but stable, with no safety indicators.
What it typically costs in Hendersonville

| Emergency capacitor or contactor replacement | $250–$550 | — |
| Emergency temporary cooling or heating | Varies | If parts cannot be sourced overnight, a good contractor's first move is making the home safe — not selling you a system at 1am. |

Facts that change the math
Tennessee requires a state contractor's license for projects of $25,000 or more, and a Home Improvement license for smaller residential jobs in certain counties — Davidson, Rutherford, Robertson, Knox, Shelby, Hamilton, Marion and Haywood among them. You can verify any contractor's license yourself at verify.tn.gov before you sign anything or hand over a deposit.
Questions worth asking
Ask these and you will very quickly learn whether the person in your driveway is diagnosing or selling.
- What is the after-hours rate, and does the diagnostic fee apply to the repair?
- If the part is not available tonight, what can you do to make the home safe?

Common questions
Do you actually answer the phone at 2am in Hendersonville?
Yes. Every call to this line is answered live, at any hour, including weekends and holidays. You will not reach a voicemail box or an overnight answering service that takes a message and calls back in the morning.
Do I need a permit from the City of Hendersonville to replace HVAC equipment after storm damage?
Yes, if the repair involves a full system replacement rather than a component swap, it goes through the City of Hendersonville Codes Department, same as new construction. This comes up a lot after wind or lightning damage from storms like the December 2023 outbreak. A licensed contractor handling your emergency repair should pull that permit as part of the job, not leave it to you.
What should I do while waiting for a technician?
In a heat emergency: close blinds on sun-facing windows, run ceiling fans, move vulnerable people to the lowest floor, and hydrate. In a cold emergency: close off unused rooms and use only safely-rated space heaters — never a stove or oven. If you suspect carbon monoxide, leave the house first and call from outside.
Is emergency service more expensive?
Yes, and any contractor claiming otherwise is building it in somewhere else. Expect a premium on the after-hours trip charge. What should not change is the price of the parts.
