When It Can’t Wait

24/7 Emergency HVAC Repair in Sussex County, NJ

A heating or cooling failure isn’t always something that can wait until Monday. In a Sussex County cold snap, a dead furnace can put pipes — and vulnerable family members — at real risk. In a heatwave, a failed AC turns a home dangerous for kids, older adults, and pets within hours.

We’re a local, family-owned team based right here in Newton. When you call our emergency line, you reach real, experienced technicians — not a national call center routing you to whoever’s available. We arrive with stocked trucks to diagnose and fix the problem fast.

Emergencies we respond to

No heat

Furnace, boiler, or heat pump that won’t keep up or won’t run at all — the call we take most on the coldest nights of the year.

No cooling

AC blowing warm or dead in a heatwave, when indoor temperatures climb fast and become a health risk.

Burning or gas smells

Electrical burning odors or a suspected gas issue — shut the system down, get everyone safe, and call us immediately.

Water leaks & frozen coils

Active leaks from an air handler or a frozen, iced-over system that’s shut down — handled before it causes damage.

Tripping breakers

A system that keeps tripping the breaker is telling you something is wrong electrically — never keep resetting it; let us diagnose it.

Strange noises & shutdowns

Grinding, screeching, or banging followed by a shutdown usually means a failing motor or compressor that needs immediate attention.

Why homeowners call us first

Anyone can advertise emergency service. What matters at 2 a.m. is who actually picks up — and who shows up. We don’t use rotating subcontractors or out-of-state call centers. You get our own licensed technicians (NJ HVACR #19HC00108700) who know the local homes, the local equipment, and the fastest route to your door.

We’ve kept Newton, Sparta, Vernon, Hopatcong, and the rest of Sussex County comfortable since 1999. That track record is built on showing up when it counts — and being straight with you about what’s wrong and what it takes to fix it.

Shut the system down and call now if you notice

  • A burning, electrical, or hot-metal smell from vents or the unit
  • Any smell of gas (leave the home first, then call)
  • A breaker that trips repeatedly when the system runs
  • Grinding, screeching, or banging from the furnace or AC
  • No heat with outdoor temperatures near or below freezing
  • Water actively leaking around the furnace or air handler

Frequently Asked Questions

Do you really answer 24/7?

Yes. Our emergency line is staffed around the clock, including nights, weekends, and holidays — and it’s answered by our own team, not a third-party service. Heating and cooling failures don’t keep business hours, and neither do we.

What counts as an HVAC emergency?

Anything that threatens safety or risks fast damage: no heat in freezing weather (pipes can freeze), no cooling in a heatwave (a danger to kids, seniors, and pets), any burning or gas smell, repeated breaker trips, or active leaks. If you’re unsure, call — we’ll help you decide whether it can wait.

My furnace smells like burning — what should I do?

If it’s a faint dusty smell the first time you run the heat each season, that’s usually normal. But a persistent burning-plastic, electrical, or hot-metal smell means you should shut the system off at the breaker (not just the thermostat) and call us right away — overheating wiring is a fire hazard. If you smell gas, leave the house first, then call.

Will I pay a huge premium for after-hours service?

We’re upfront about pricing before any work begins, including any after-hours rate — no surprises tacked on after the fact. We’d rather earn a long-term customer than gouge you on a bad night.
