HVAC emergencies in Salt Lake City span the full diversity of the city’s residential equipment. Winter brings boiler failures in historic Avenues homes that leave entire households without heating, furnace failures across mid-century neighborhoods, mini-split heat pump issues in historic homes that rely on ductless equipment for both cooling and supplemental heating, and the standard atmospheric-vent furnace problems common in equipment older than typical service life. Summer brings AC failures across the equipment spectrum from central AC in newer construction to mini-split systems in historic homes. CO concerns are particularly relevant given the city’s older housing stock and combustion equipment. Gas safety issues require coordination with Dominion Energy and emergency services. Each scenario requires different expertise, different parts inventory, and different response considerations.
We provide 24/7 emergency HVAC response to Salt Lake City through our on-call technician system. Our shop at 4454 Manhattan Ct in West Valley City positions us with neighborhood-dependent response times — westside and central Salt Lake City locations typically 1.5–3 hours during business hours, Avenues and East Bench typically 2–3 hours, upper foothill locations 2–4 hours. Service trucks carry inventory matched to Salt Lake City’s diverse equipment landscape including boiler components for historic-home systems, furnace parts across equipment generations, and mini-split heat pump diagnostic tools. Maintenance plan customers receive priority emergency scheduling.
Below is what qualifies as an HVAC emergency, what to expect from our response, what to do while you wait, and how emergency pricing works.
When to Call for Emergency Service
Heating Emergencies
- No heat with sub-freezing outdoor temperatures
- No heat with vulnerable occupants — elderly residents, infants, anyone with respiratory or temperature-sensitivity conditions
- Furnace running but no heat output
- Furnace running constantly without reaching setpoint during severe cold
- Boiler pressure dropping repeatedly during cold weather — indicates leak or system issue
- Boiler not heating despite operating — circulator pump failure, zone valve failure, or other distribution issue
- Radiators cold while boiler runs — air in system, circulator failure, or zone control issue
- Strange burning smell from heating equipment
- Equipment making unusual loud noises
- Smoke or visible flame outside the firing chamber
- Back-drafting from atmospheric-vent equipment
- Mini-split heat pump not heating during cold weather
Cooling Emergencies
- No AC with extreme heat — particularly with vulnerable occupants
- AC running but no cooling
- Mini-split system completely failed during heat wave
- Water leaking from indoor equipment
- Burning smell from cooling equipment
- Equipment making unusual loud noises
- Frozen outdoor unit or visible ice on refrigerant lines
Safety Emergencies (Call 911 First If Necessary)
- CO detector alarm — leave the home and call 911. After clearance, call us for combustion analysis and equipment evaluation.
- Strong gas smell — leave the home and call Dominion Energy gas leak emergency 1-800-323-5517 or 911. After clearance, call us for equipment evaluation.
- Occupants showing symptoms of CO exposure — headache, dizziness, nausea, confusion. Get outside and call 911.
- Visible fire or smoke from equipment — call 911 immediately.
What Doesn’t Require Emergency Response
- Furnace failure during moderate weather (40°F+)
- AC failure during moderate weather (75°F or cooler)
- Slow water leak that can be contained with a bucket
- Equipment working but inefficiently
- One mini-split zone not working when others function
- Cosmetic issues without operational impact
- Maintenance items that have been waiting weeks or months
What to Do Before We Arrive
For Furnace Failure
- Check that the thermostat is set to “heat” mode and setpoint is above current temperature
- Check that breakers haven’t tripped
- Check that the furnace switch is in the “on” position
- Check that the air filter isn’t extremely dirty
- Listen for any unusual sounds
- Keep the home as warm as safely possible
- Run faucets at a trickle if temperatures are near freezing to prevent pipe freeze
For Boiler System Failure
- Check boiler pressure gauge — typical 12–15 PSI cold operating range
- Check that emergency switch (typically red-colored switch near boiler) is in “on” position
- Check that water level is adequate (auto-fill systems usually maintain this)
- Listen for circulator pump operation
- Check if specific radiators are cold while others are warm — indicates distribution issue
- Don’t bleed radiators yourself unless experienced — improper bleeding can introduce more air problems
- Run faucets at a trickle if temperatures are near freezing to prevent pipe freeze
For Cooling Failure
- Check that the thermostat is set to “cool” mode
- Check that breakers haven’t tripped
- Check the outdoor unit for visible debris blocking airflow
- Check that the indoor unit isn’t producing visible icing
- For mini-splits: check filters for cleanliness
- Reduce indoor heat sources
- Close blinds and curtains
- Stay hydrated and cool
For Safety Concerns
- CO alarm: get outside immediately, call 911
- Gas smell: don’t turn anything on or off, get outside immediately, call Dominion Energy 1-800-323-5517 or 911
- Symptoms of CO exposure: get outside immediately, seek medical attention
- Visible fire/smoke: evacuate, call 911
What to Expect from Emergency Response

On-Site Emergency Response
The emergency technician:
- Verifies emergency conditions
- Performs immediate diagnostic appropriate to equipment type
- Tests CO levels on gas equipment
- Implements immediate repair if parts are on the truck
- Provides written quote for repair work before proceeding
- Restores equipment operation when possible
- Coordinates follow-up work if extensive repairs needed
- Documents all measurements and work performed
If Same-Visit Repair Isn’t Possible
For situations requiring follow-up work — specialty parts ordering, major equipment failures requiring replacement scheduling, safety conditions requiring more comprehensive assessment, heat exchanger problems requiring isolation testing — the technician makes the equipment safe, provides temporary solutions where possible, and schedules priority follow-up. For complete equipment failures during severe weather, we discuss interim heating/cooling options with you.

Frequently Asked Questions
How fast can you respond to an emergency in Salt Lake City?
Depends on neighborhood and time of day. Westside neighborhoods 1.5–2.5 hours, central and Avenues 2–3 hours, East Bench 2–3 hours, upper foothill 2–4 hours during business hours. After-hours adds 1–2 hours to these estimates. Maintenance plan customers receive priority scheduling.
What does an emergency call cost in Salt Lake City?
Business hours emergencies have no premium — diagnostic $99–$199 applied to repair. After-hours emergencies add $50–$150 premium. Sunday/holiday emergencies add $100–$200 premium. Maintenance plan customers get diagnostic fees waived plus 10–15% repair discounts.
My boiler stopped working and the house is getting cold. Is this an emergency?
Yes, particularly during winter cold weather. Boiler failures leaving historic homes without heating require immediate response — frozen pipes risk is significant, comfort is impacted, and boiler systems sometimes have complications that require expert diagnosis. Call our emergency line for response.
Can you respond to my Capitol Hill home during a snowstorm?
Yes, though severe winter weather may extend response times due to road conditions and increased call volume. We prioritize confirmed emergencies (no heat with sub-freezing temperatures, CO concerns, gas safety) during severe weather events. Vehicle equipment includes appropriate winter capabilities.
My mini-split isn’t heating during this cold snap. What should I do?
Most mini-splits maintain heating capability at the temperatures Salt Lake typically experiences, though heating output declines as outdoor temperature drops. If your mini-split has stopped heating entirely, the cause is usually inverter compressor issue, defrost cycle malfunction, or refrigerant problem. Call for emergency response if your home temperature is dropping with no heating. Some mini-split installations include electric heat strips that activate during severe cold — if those have failed, that’s also a service issue.
What if my CO detector goes off?
Get outside the home immediately and call 911. Don’t re-enter until emergency services clear the home. After clearance, call us for combustion analysis, equipment evaluation, and source identification. CO concerns are particularly relevant in Salt Lake City given the older housing stock.
What if I smell gas?
Don’t turn anything on or off. Get outside immediately. Call Dominion Energy gas leak emergency 1-800-323-5517 or 911. After clearance, call us for equipment evaluation.
Should I get a maintenance plan?
For Salt Lake City customers with older equipment, boiler systems, mini-split installations, or histories of using emergency service, yes — maintenance plan diagnostic fee waivers alone often pay for the plan if you have one emergency call. Plus the parts and repair discounts apply to all emergency work.
