What counts as an HVAC emergency?

Life-safety concerns (CO alarm activation, natural gas or LP odor), no heat during heating season with outdoor temperature below 40°F, no cooling during heat waves with outdoor temperature above 90°F, water leaking from equipment with property damage risk, breakers repeatedly tripping on HVAC circuits, and commercial refrigeration failures affecting business operations. Non-emergencies during business hours: routine service calls, tune-up scheduling, quote appointments. Emergency dispatch fees apply to after-hours emergency calls; business-hours emergencies are billed at standard service call fees.

What are emergency dispatch fees?

Emergency dispatch fee runs $145 for evenings (5 PM to 10 PM, Monday through Saturday) and $195 for overnight (10 PM to 8 AM), Sundays, and holidays. The dispatch fee covers the technician's on-site diagnostic; hourly labor is charged separately at the emergency service rate; parts billed separately. Priority Maintenance Plan members have dispatch fees waived and receive priority routing regardless of dispatch queue depth. Commercial after-hours dispatch fee is $195 flat for evenings, weekends, and holidays; commercial hourly labor rate is $185/hour plus travel time.

How fast will PolarCore arrive during an emergency?

Response times vary by location and dispatch queue depth. Columbia proper: under 90 minutes typical, 25-45 minutes for many emergencies. Jefferson City, Fulton, Mexico, Centralia, Boonville: 25-60 minutes typical during business hours; after-hours dispatch typically adds 15-30 minutes. Rural county addresses: 45-90 minutes typical. During peak arctic outbreak or heat wave events with multiple simultaneous emergency calls, response can stretch to 3-6 hours during the peak 48-hour windows. Vulnerability triage prioritizes households with infants, elderly, or medical equipment dependencies. Priority Maintenance Plan members receive priority routing regardless of queue.

Should I stay in my house if my heat is out during a cold snap?

Depends on how cold it is and how vulnerable the occupants are. General guidance: if outdoor temperature is below 20°F and heat has been out more than 2-4 hours, indoor temperature is dropping toward levels that risk pipe freezing and occupant health impacts. Vulnerable occupants (infants, elderly, medically compromised) should relocate to family, friends, or emergency shelter well before indoor temperature drops significantly. If you're staying: block off unused rooms, gather in the smallest space with the family, use extra blankets, and open cabinet doors to expose pipes to remaining indoor heat. Never use gas ovens, charcoal grills, or portable generators for indoor heat — CO poisoning risk is real and has caused deaths during past Missouri arctic outbreaks. Call 211 for United Way information on emergency warming centers.

Can I get emergency service if I've never used PolarCore before?

Yes. PolarCore accepts emergency dispatch calls from any customer regardless of prior service history. First-time emergency customers receive the same response, diagnostic, and repair service as existing customers, though Priority Maintenance Plan members have dispatch fees waived. After the emergency dispatch, customers can enroll in Priority Maintenance Plan to receive ongoing benefits including waived after-hours dispatch fees, 15% repair discount, and annual tune-up scheduling.

Emergency HVAC Repair in Columbia, Missouri

Emergency HVAC dispatch runs 24 hours a day, 7 days a week from the Corona Road office in southwest Columbia across the five-county service area (Boone, Cole, Callaway, Audrain, Cooper). PolarCore has completed 47 arctic outbreak emergency repairs across the service area 2022–2025, plus routine emergency dispatch for no-cool during summer heat waves, CO alarm activations, and natural gas or LP equipment concerns. Emergency dispatch triage prioritizes life-safety concerns (CO alarms, natural gas or LP odor) first, followed by no-heat calls during heating season with outdoor temperature below 40°F, no-cool calls during heat waves with outdoor temperature above 90°F, and other emergencies. Truck loadout matches season: winter carries igniters, flame sensors, pressure switches, gas valve components, universal control boards; summer carries capacitors, contactors, condenser fan motors, thermostat replacements, and R-410A refrigerant for legitimate low-charge situations after leak repair.

What Qualifies as an HVAC Emergency

CO alarm activation — life safety, always emergency. Leave the house, call 911, then call PolarCore for equipment evaluation before restart.
Natural gas or LP odor — life safety. Natural gas: call Spire emergency 800-887-4173. LP: call your LP supplier’s emergency line. Then call PolarCore.
No heat during heating season with outdoor temperature below 40°F or forecast below freezing within 12 hours — priority routing for households with infants, elderly, or medically vulnerable occupants.
No cooling during heat wave with outdoor temperature above 90°F or heat index above 100°F.
Water leaking from HVAC equipment that could cause property damage.
Breaker tripping repeatedly on HVAC circuit — electrical safety concern.
Frozen indoor coil with water damage risk.
Commercial refrigeration or HVAC failure affecting business operations, food safety, or occupant comfort.

Peak Event Response

February 2021 Arctic Outbreak

Sustained sub-zero overnight lows February 14–17, 2021 with actual thermometer readings of −5 to −15°F. PolarCore completed 47 emergency no-heat repairs across the five-county service area during the 4-day peak period, with dispatch queue peaking at 8–12 hours during the coldest 48-hour window. Vulnerability triage prioritized households with infants, elderly, and medical equipment dependencies.

January 2024 Arctic Outbreak

Similar arctic outbreak event mid-January 2024. PolarCore completed 34 emergency no-heat repairs. Common failure modes: hot surface igniters that were degraded going into the season, LP tank pressure drop at nearly-empty tanks in cold ambient conditions, and pressure switch trips on rural PVC vent installations subject to wind-induced downdraft.

August 2022 Heat Wave

Extended heat wave August 15–27, 2022 with daily highs 95–102°F. PolarCore completed 38 emergency AC repairs across the service area. Capacitor failures dominated the failure mix as aging capacitors reached end of service life under peak load; contactor failures and condenser fan motor failures accounted for the rest.

What to Do Before PolarCore Arrives

No-Heat Winter Emergency

Check thermostat set to Heat mode with setpoint above indoor temperature. Confirm batteries in non-hardwired thermostats.
Check furnace power switch is On.
Check furnace circuit breaker — if tripped, reset once.
Check furnace filter — heavily loaded filter can trip safety limit switch.
For LP equipment: check tank gauge for adequate fuel.
Any natural gas or LP odor: leave the house, call appropriate emergency line first.

No-Cool Summer Emergency

Check thermostat set to Cool mode with setpoint below indoor temperature.
Check AC circuit breaker (typically two breakers — air handler and outdoor unit).
Check outdoor unit is running. If not, check the outdoor disconnect box.
Check filter and replace if heavily loaded.
Check indoor coil area for ice buildup — if visible ice, shut off AC and let coil thaw before continued operation.
