Emergency HVAC repair in Memphis, TN

When is an HVAC problem an emergency in Memphis?

Memphis runs two emergency seasons — a humid 96°F summer and a near-freezing winter — but the fastest-moving danger isn't the ordinary weather, it's the summer storm. West Tennessee is straight-line-wind and derecho country, and the outages that follow are the real HVAC emergency: "Hurricane Elvis," the July 2003 derecho, drove 100-plus-mph winds across Shelby County and left about 339,000 Memphis Light, Gas & Water customers dark — more than 80% of the utility, its largest outage on record, some homes out for up to two weeks. It recurs — a 2025 wind-and-lightning storm knocked out 14,000 in one afternoon — and tornadoes hit the region too, with the April 2025 Mid-South outbreak producing 34 twisters and an EF3 into West Tennessee. That matters here more than almost anywhere, because Memphis carries the largest cooling load we cover (2,109 cooling degree-days) and roughly 50% of Shelby County cools on electricity against 48% on gas heat — so a downed line in July is a no-cool emergency for the majority the moment it hits, with central air near-universal and dead until MLGW restores power. The city still logs 2,949 heating degree-days against an 18°F design low, and a winter outage kills gas heat too, since a furnace needs power for its blower and igniter. When the lights go out, an HVAC emergency becomes a power emergency first.

When is it not an emergency — and can it wait until morning?

Plenty of after-hours calls could have been cheaper morning appointments. An air conditioner that slips a few degrees through a 96°F Delta afternoon — against the largest cooling load we cover — is working as designed, not failing is running at its physical limit, not failing; a bedroom that won't match the hallway, or a rattle that comes and goes while cooling and heat both keep working, will still be there — fixable at the standard rate — tomorrow. Save the emergency line for the list below.

Warning signs: call now, safe to wait, or check yourself first?

Run the triage before you decide what kind of call this is.

Deeper walk-throughs: AC won't start, furnace won't start, and HVAC smells.

What should you do while you wait for the technician?

Help booked, hours to fill — and in Memphis the summer half is the one that bites. Shelby County runs one of the longest, hottest cooling seasons we cover, under a 96°F design high, so a no-cool afternoon in Delta humidity is a genuine heat-safety event: move to a low, shaded floor, keep water close, and pull the blinds before the house loads up. Heating splits almost evenly between gas and electric, so on the rarer no-heat night, close off one room and keep any combustion source out of it.

Each situation has its own walk-through: what to do when the AC quits in dangerous heat and what to do when the heat fails.

Gas smell, a CO alarm, or a generator running indoors: this outranks every step above — leave the house immediately, touch no switches, and call MLGW's gas line and 911 from outside before anyone re-enters.

Carbon monoxide — from the furnace, and from the storm generator

Memphis heating is close to a coin-flip, so a cracked heat exchanger threatens the 48% of homes on gas — nearly half the city — while two CO sources make this a life-safety section for everyone. A gas furnace's cracked exchanger or blocked flue can leak carbon monoxide into the supply air; and after a derecho or tornado outage, a portable generator run indoors or too near a window is the deadliest source of all — a bigger risk here precisely because a cooling-dependent county loses its air conditioning when the grid drops in July and reaches for a generator. The gas is odorless and colorless, and the poisoning imitates the flu without the fever:

Detectors go on every level and near sleeping areas, not beside the furnace, tested each season — and a generator runs outdoors only, well away from windows. An alarm or those symptoms mean everyone outside, then MLGW's gas line ((901) 528-4465) and 911 from the street. Full guide: furnace carbon-monoxide safety.

Emergencies and vulnerable residents — the health signs that mean 911

Lost cooling or heating lands hardest on infants, elders, and anyone managing a chronic condition — and in the hottest summers we cover, the heat side is the one that turns deadly fastest. The equipment is the contractor's job; these signs in a person come first and go to 911.

How much does emergency HVAC repair cost in Memphis?

The daytime diagnostic in Memphis runs $70–$185 — walk away and that's the whole bill; approve the repair and most shops fold it into the total, mechanics covered in the service-call fee guide. Off the clock the math usually changes: evenings, weekends, and holidays commonly price at roughly 1.5 to 2 times standard — though it isn't a rule. A Memphis chain advertises 24/7 emergency service at the same price with no additional fees, and a national franchise here says its after-hours rate varies by location and is quoted ahead of time, which is exactly why a straight answer on your window comes before the truck moves.

Is it a power problem or an equipment failure?

Rule out the electrical panel before declaring the equipment dead — plenty of midnight "failures" are one tripped breaker, and in a region with Memphis's storm history a good share are MLGW outages, not broken HVAC. Memphis has a single utility for both fuels, so it's one company to call — but still two numbers: a power emergency is MLGW's electric outage line ((901) 544-6500) and a gas emergency is MLGW's gas line ((901) 528-4465).

Whole-home outage

if the lights are out too, it's MLGW's problem rather than your equipment, and the system should restart on its own once power returns, after the compressor's built-in delay — but with central air nearly universal here that means no cooling until MLGW does. Report it, or a downed line, at (901) 544-6500 or 911.

One dead circuit

check the main panel and the outdoor disconnect; a single tripped breaker earns one reset.

It keeps tripping

a second trip right after a reset is the system shielding you from a real electrical fault. Leave it off and make the call — resetting into a fault can take out the compressor.

What can actually be fixed tonight — and what waits for morning?

Set the expectation before the driveway conversation: overnight work is limited to what's already on the truck, with everything else bridged until parts arrive.

Fixed on the overnight visit (truck stock)

Capacitors, contactors, hot-surface igniters, flame-sensor cleanings, thermostats, drain clears, fuses, low-voltage repairs — the short list behind most of Memphis's no-cool and no-heat calls, usually running again before the technician backs out.

Diagnosed tonight, finished later (ordered parts)

Compressors, coils, blower and inducer motors, boards, gas valves, reversing valves. The night visit nails the diagnosis and produces a written quote; the part shows up in one to three days.

Bridged in the meantime

In a July heat wave it's fans, closed blinds, a lower floor, and a thawed coil until the part lands; on the heat-pump side of the split, backup strips can carry a house through a winter gap at a higher power bill, as long as the grid is up — the technician names the bridge before leaving.

Never fixed at night

A condemned heat exchanger or an active gas leak stops the visit cold — MLGW clears the house before any repair gets scheduled. It's the safety line, not a service gap.

Will homeowners insurance pay for an HVAC emergency in Memphis?

The cause decides the claim, and in Memphis the storm side is more than hypothetical. Equipment that simply gave out — the compressor that died mid-heat-wave, the igniter that failed at 18°F — is wear and tear, excluded from standard homeowners policies (Allstate and Progressive both spell this out). What a storm does is different: lightning, hail, straight-line wind, a fallen limb or debris through the condenser, or a burst pipe flooding the furnace are covered perils under dwelling coverage, paid minus the deductible — and the Mid-South's derecho and tornado record brings down exactly the limbs and lines that cause them.

Storm-caused? Photograph before anything moves, file quickly, and keep the emergency invoice — the technician's written cause-of-failure note is the evidence an adjuster wants. For plain mechanical death, the only insurance answer is an equipment-breakdown endorsement added before the failure; it can't be bought after.

No heat as a renter — what Tennessee law requires

Tennessee's Uniform Residential Landlord and Tenant Act applies only in counties over 75,000 people, and Shelby County — the state's most populous — qualifies, so §66-28-502 governs here. Heat, gas, and electricity are "essential services" a landlord must supply. The lever is written notice: after it, the statute lets a tenant procure the service and deduct the cost, recover the diminished rental value, or arrange substitute housing with the rent excused while the service is out. Date and keep everything. One honest limit worth knowing — and it bites hardest here, in the hottest city we cover — air conditioning is not an essential service under Tennessee law, so a dead AC in a July heat wave doesn't carry the same legal lever a dead furnace does, even though it's the more dangerous failure. A licensed contractor can be routed to the property either way, but the bill's owner is a landlord-tenant question, so the paper trail comes first.

How fast can a contractor reach you across Memphis?

The line answers around the clock. Memphis's queue is a summer problem before it is a winter one: the city carries the largest cooling load we cover, so a July heat run puts the whole of Shelby County on the phone in the same afternoon. Straight-line wind events do the same thing faster — the 2003 derecho took power from the great majority of MLGW's customers at once — and on those days an emergency HVAC dispatch cannot outrun a restoration crew. A search for "emergency HVAC near me" in Memphis resolves through your location, so calls from Midtown, East Memphis, Cordova, or Whitehaven — ZIPs 38104, 38117, 38018, 38116 — land with a Tennessee contractor who covers that ground.

How can you avoid the 2 a.m. HVAC emergency?

Most overnight failures telegraph themselves weeks ahead — maintenance is how you hear it.

• Book the spring AC tune-up before the first heat wave — Memphis carries the largest cooling load we cover, and a capacitor or contactor caught in April is the July 2 a.m. call you never place; then verify the heat side before the first freeze.
• Change the filter monthly whenever the system runs daily — and it runs most of the year here.
• Test CO and smoke detectors in spring and fall, before either season leans on the equipment.
• Keep a plan for storm outages — a safely-sited generator, never indoors, and a cool or warm room you can close off — because in a cooling-dependent city a summer derecho that drops MLGW lines is a no-cool event for most homes at once.
• Find the breaker panel, the furnace switch, and the outdoor disconnect before a 2 a.m. hunt in a dark mechanical room.
