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 Hermitage
Second-generation replacements in Hermitage were often sized off the original 1970s load calculation, before anyone added insulation or replaced windows. That legacy oversizing is why so many homes here feel cold and damp at once.

On the ground in Hermitage
Hermitage runs heavy on 1970s through 1990s construction, and a lot of that housing stock around Old Hickory, Andrew Jackson, Tulip Grove, and Dodson Chapel is on its second HVAC system now, sometimes its third. Second systems don't fail gently. They run fine until a July afternoon or a January cold snap pushes them past whatever life they had left, and that's when the after-hours calls come in — no cooling with the house climbing into the 80s, or no heat with pipes at risk.
The March 2020 tornado also left its mark on this end of Davidson County. A fair number of the units in this area went in as rushed replacements afterward, and rushed work sometimes means a disconnect box or duct connection that was never quite right, showing up years later as a burning smell or a CO alarm going off at 2am.
Here's the thing worth knowing before you call anyone: if your house always runs cold and clammy at the same time, that's not usually a broken unit — it's a system sized off a 1970s load calculation that's now oversized for a house with better windows and insulation. It short-cycles, cools fast, and never runs long enough to pull the humidity out.
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
- Water actively coming through a ceiling below an air handler
- 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.

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 Hermitage?
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.
Does emergency HVAC replacement in Hermitage require a permit before the work can be done?
Yes. Any HVAC equipment replacement in Hermitage falls under Metro Nashville Department of Codes and Building Safety, and that applies even when the old unit failed overnight and needs to go in fast. A licensed contractor can usually pull the permit after the fact and get the system running same-day, but skipping it entirely can cause problems later with resale or insurance.
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.
