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 Mount Juliet
Many Mt. Juliet systems were installed in the same post-2020 rebuild window, which means warranties are now expiring in clusters. Check your install date before paying out of pocket for a part that may still be covered.
- Housing stock
- Fast-growth subdivision construction, much of it post-2005, plus older stock near Percy Priest and Old Hickory lakes.

- The March 3, 2020 tornado tore directly through Mt. Juliet, and a large share of the city's roofs date to the rebuild that followed.
- Permits issued by
- City of Mt. Juliet Public Works and Codes

On the ground in Mount Juliet
Mount Juliet grew fast after 2005, and then grew again after March 2020, when the tornado tracked straight through the city and took a big chunk of the housing stock with it — roofs, siding, and in a lot of cases the HVAC equipment sitting on slabs or in attics. If you're in Providence, Willoughby, Nichols Vale, or parts of Del Webb, there's a real chance your system was installed in the same rebuild window as half your street's. That matters at 11pm when a unit dies: a lot of those systems are hitting the same age at the same time, so check your install date and paperwork before you assume a failed compressor or board is an out-of-pocket repair. It may still be under warranty.
Older homes near Percy Priest and Old Hickory lakes tend to have different equipment entirely — sometimes heat pumps pushed hard by lake humidity, sometimes units wedged into tight crawlspaces that make an after-hours diagnosis slower. Waverly and the older lake-adjacent streets see more of these calls in July and January than the newer subdivisions do.
Whatever the address, no cooling with the house climbing past the mid-80s, no heat under freezing, a burning smell at the unit, a sounding CO alarm, or water coming through a ceiling below an air handler are not wait-until-morning situations.
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.

| 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?

Faster by phone, especially after hours — but if you would rather not call, give us the essentials and a local contractor will reach out.
Common questions
Do you actually answer the phone at 2am in Mount Juliet?
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 Mt. Juliet if my HVAC system has to be replaced in an emergency, at night or on a weekend?
Yes, but it doesn't hold up the repair. City of Mt. Juliet Public Works and Codes still requires a permit for full system replacement, and a licensed contractor can pull it the next business day even though the install happens right away. What you should avoid is anyone offering to skip the permit entirely — that can cause problems later with warranty claims or when you sell the house.
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.
