Emergency Furnace Repair — Chicago & Suburbs

Emergency furnace repair in Chicago, in brief

Emergency furnace repair in Chicago is handled by SAVA HVAC & Appliance Repair, a family-owned company founded in 2017 and based at 6502 W Devon Ave. The emergency line, (773) 558-3332, is answered 24/7: tell us what the furnace is doing and confirm your address, and we give you the earliest available arrival window. Many no-heat calls are resolved in the same visit when the part is on the truck, among them failed igniters, flame sensors, thermostats, blower motors, control boards and pressure switches. The service call starts from $79 with a 30-minute diagnostic, credited toward the repair, and you decide whether to go ahead. EPA Section 608 Certified technicians repair gas furnaces, boilers and heat pumps across Chicago and the North Shore. Regular appointments run Monday through Saturday, 8 AM to 6 PM. If you smell gas, leave the house and call 911 and your gas utility first.

Emergency furnace repair: key facts

When the furnace fails in a Chicago winter, every hour matters

No heat in Chicago isn't just uncomfortable — it can be dangerous. Indoor temperatures drop fast when outdoor temps plunge below freezing, and frozen pipes can cause thousands in water damage within hours. Cold is especially risky for kids, seniors, pets, and anyone with health conditions.

SAVA HVAC answers emergency furnace calls 24 hours a day, 7 days a week — including nights, weekends, and holidays. When you call, we check the schedule and give you an arrival window based on what's actually available.

If you smell gas — leave the house first

1. Do NOT use light switches, phones, or anything that could spark inside the house
2. Leave the house immediately and take pets with you
3. From outside, call your gas utility's emergency line:
      Peoples Gas: (866) 556-6004
      Nicor Gas: (888) 642-6748
4. Once the gas leak is shut off and the utility clears the home, call SAVA to diagnose the furnace at (773) 558-3332

What to tell us when you call

A no-heat call moves faster when we know what we are walking into. It helps to know:

1. Thermostat — is the screen lit or blank, what is it set to, and what is it reading?
2. What the furnace does — nothing at all, or does it start and shut down after a few minutes?
3. Control board LED — most furnaces blink a fault code through a small window. Count the flashes.
4. What changed — did it stop suddenly, struggle for days first, or follow a storm or power cut?

Don't keep resetting the furnace — repeated reset attempts can flood the burner with unignited gas. If it has stopped producing heat, leave it OFF and call us.

Call us immediately if you have:

1. No heat in subzero weather — pipes can freeze and burst within hours
2. Carbon monoxide alarm sounding — leave the house, call 911, then call us
3. Burning smell from the furnace or vents
4. Loud banging, rumbling, or grinding from the unit
5. Soot or black marks around the furnace or vents
6. Water leaking from the furnace or boiler
7. Yellow or flickering flame (should be steady blue)

What we fix same-day

Most no-heat calls we see in Chicago can be resolved when parts are on the truck:

More on specific symptoms: blowing cold air, not turning on, short cycling, making noise, leaking water, burning smell.

Heat exchanger replacement and major component swaps may need parts to be ordered. We'll tell you upfront if that's the case.

Brands we service

Plus most other residential heating brands — if yours isn't on the list, call and we'll confirm.

What we DON'T service

To set expectations: SAVA HVAC does not service oil furnaces, wood stoves, fireplaces, or standalone space heaters. We focus on gas furnaces, electric furnaces, hot water boilers, and heat pumps — that's where our certifications and parts inventory live.

What happens when you call

1. You call — describe what's happening (or just say "no heat")
2. We confirm your address — make sure you're in our service area
3. We check availability — give you the earliest available arrival window
4. Tech arrives — diagnose, walk you through what we found, you decide whether to go ahead
5. Many repairs done same visit when the part is on the truck — if a part needs ordering, we tell you upfront
