Some HVAC failures cannot wait for business hours. A furnace that dies overnight in January puts your pipes and your family at risk. An AC that quits during a heat wave is dangerous for infants, older adults, and anyone with health conditions. Werth-Aire provides 24/7 emergency HVAC response across Pittsburgh and the surrounding communities for exactly these situations.
When you call, we start with safety. If there is a gas smell, soot, smoke, or a suspected carbon-monoxide problem, we tell you to leave immediately and call 911 or the gas utility first — no HVAC repair is worth a combustion risk. For a no-heat or no-cool emergency without a gas hazard, we give you an honest arrival window and safe steps to take while you wait.
Our emergency technicians carry the common failure parts and diagnose the true fault on the spot, with a flat-rate quote before we begin. We explain the after-hours fee structure up front, so an urgent repair never turns into a surprise bill.

Same-day appointments · honest flat-rate pricing
Safety first. The first job on any emergency call is ruling out a combustion hazard. If you smell gas, see soot or smoke, or a carbon-monoxide alarm sounds, this is not an HVAC repair — leave the building immediately, call 911 or your gas utility from outside, and do not restart the equipment. Everything else can wait until you are safely out.
While you wait for us
Rule out a hazard first
If there is any gas smell, soot, or CO alarm, skip the rest of this list — get out and call 911. Only troubleshoot a system you are certain is safe.
Check the obvious basics
Confirm the thermostat is set and calling, look for a tripped breaker or a flipped equipment switch, and replace a badly clogged filter — these resolve a surprising share of after-hours calls.
Protect the vulnerable
In a hard freeze, open cabinet doors under sinks on exterior walls to slow pipe freezing. In a heat wave, move infants and older adults to the coolest room and keep them hydrated.
Do not repeat-reset
Resetting a system that keeps locking out can turn a small fault into a bigger one. Note what it is doing and call (831) 461-3437 with the details.
When to call for emergency service
- No heat during freezing weather, with pipes at risk
- No cooling during a dangerous heat wave
- Active water leaking from the system into the home
- The system repeatedly trips the breaker or shuts down
- Ice buildup shutting down a heat pump or AC
- Any gas smell, soot, or CO alarm — leave and call 911 first, then us

How we handle an after-hours call
When you call outside business hours, we start with safety — screening for gas, combustion, and carbon-monoxide hazards before anything else, and telling you to leave and call 911 first if there is a real combustion risk. For a no-heat or no-cool emergency without a gas hazard, we give you an honest arrival window for your area and safe steps to take while you wait. Our emergency trucks carry the common failure parts, we diagnose the true fault on site, and we quote the repair flat-rate with the after-hours fee explained before we dispatch. For a total heat loss in winter, our no-heat repair gets top priority.
What affects the cost
Emergency repairs are quoted flat-rate before work begins, with the after-hours fee explained on the call. Cost drivers:
- The failed component and whether the part is on the truck
- After-hours, weekend, or holiday timing
- Any safety corrections required to operate the system
- Refrigerant work on cooling emergencies
We explain the after-hours fee structure before we dispatch, and quote the repair flat-rate on site — no surprise emergency billing.
