Danger first. Smell gas or hear a carbon monoxide alarm? Leave the home and call 911 or your gas utility from outside: PSE 1-888-225-5773 or Cascade Natural Gas 888-522-1130. Smoke or fire: call 911. More in what to do if you smell gas.
Most home emergencies have one safe first step you can take before help arrives. Heating and cooling problems get a technician after hours; plumbing and electrical problems are made safe now and booked for the first available business-hours visit. Find your situation:
| Emergency | Do this first | Then |
|---|---|---|
| Gas smell | Leave, leave the door open, don't flip switches or use a landline | Call 911 or the gas utility from outside |
| Carbon monoxide alarm or symptoms | Get everyone into fresh air | Call 911; have fuel-burning equipment checked before reuse |
| No heat in freezing weather | Check thermostat, breaker and filter; gather in one warm room | Call us (emergency furnace repair) |
| No cooling in extreme heat | Check thermostat and breaker; move vulnerable people somewhere cool | Call us |
| Burst pipe or water spreading | Shut the main water valve | Book a plumber by phone or online; visits are Monday to Friday, 8 to 5, same-day when possible |
| Water heater leaking | Turn off its cold water supply and its gas or power | Book a plumber by phone or online; visits are Monday to Friday, 8 to 5, same-day when possible |
| Burning smell or sparks at an outlet or panel | Don't touch the panel; turn off the circuit only if it is safe to reach | Call 911 for smoke or fire; then book an electrician for the first available business-hours visit |
| Power out on one part of the home | Check for a tripped breaker once; don't keep resetting it | For a neighborhood outage, call your utility; otherwise book an electrician by phone or online, same-day when possible |

Home Comfort Alliance handles emergency furnace, heat pump, ductless and air conditioning repair after hours for qualifying emergencies, for all major brands, in every city we serve. Heating calls spike on the first cold nights of fall and during winter freezes; cooling calls spike in heat waves like June 2021.
Our licensed plumbers work Monday to Friday, 8 AM to 5 PM. You can book a visit by phone or online, and we schedule the first available opening, same-day when possible, for burst pipes, leaks, water heaters and backed-up indoor drains in homes. Until then, shut the main water valve; most homes have it where the water line enters, often in a basement, crawl space or garage. Home Comfort Alliance plumbing work is residential, and we don't do sewer line work.
Our licensed electricians work Monday to Friday, 8 AM to 5 PM. You can book a visit by phone or online, and we schedule the first available opening, same-day when possible, for burning smells, sparking outlets or panels, breakers that keep tripping and partial power loss. Until then, turn off the affected circuit only if it is safe to reach, and don't open or work inside the panel. Call 911 for smoke or fire. If the whole neighborhood is dark, the problem is the utility's, so call your electric utility to report the outage.
An after-hours heating or cooling call with Home Comfort Alliance has a $330 after-hours dispatch fee instead of the $119 daytime dispatch fee, plus a $72 standard or $130 deeper diagnostic fee if the problem needs diagnosis. The repair itself is priced upfront: you approve the price before any work begins. Updated October 2026.
| Trade | Fee | Price |
|---|---|---|
| Heating and cooling | Dispatch (trip) fee | $119 |
| Heating and cooling | Standard / deeper diagnostic fee | $72 / $130 |
| Heating and cooling | After-hours dispatch fee (replaces the $119) | $330 |
| Plumbing | Dispatch (trip) fee | $99 |
| Electrical | Dispatch fee, includes a 30-minute diagnostic | $179 |
Prices as of October 2026, listed separately. Plumbing and electrical work is scheduled during business hours.

Our heating and cooling technicians go out after hours for problems that cannot safely wait: no heat in cold weather, no cooling in a heat wave for someone vulnerable to heat, or a burning smell, smoke or sparks from heating or cooling equipment (turn the system off first). A gas smell or carbon monoxide alarm comes first to 911 or your gas utility: leave the home and call from outside.
| Call us tonight | Usually safe to book the first business-hours slot |
|---|---|
| No heat in cold weather with a baby, an older adult or someone with a medical condition at home | The heat runs but the house is cooler than usual |
| No cooling in extreme heat for someone vulnerable to it | Air conditioning out on a mild day |
| Burning smell, smoke or sparks from equipment (system off first) | A new noise, but the system still heats or cools |
| No heat and no safe backup heat source | You have safe backup heat, such as a ductless unit or a fireplace insert, for the night |
Before you call, check the thermostat batteries and settings, the breaker for the furnace or heat pump, the furnace switch, and the filter. If the home is safe and comfortable enough to wait, booking the first business-hours visit avoids the after-hours fee.
The $330 after-hours dispatch fee applies any day of the week, including weekends and holidays, with no extra holiday surcharge. The only exception is the holidays we are closed. The $330 replaces the $119 daytime dispatch fee, and you get the repair price before any work begins.
Industry benchmarks, not our prices: Seattle-area companies commonly charge 1.5 to 2 times their daytime rate after hours, and Angi lists Seattle HVAC labor at about $80 to $150 an hour, with after-hours rates up to about $275 an hour (Angi, read October 2026). Home Comfort Alliance publishes one flat after-hours dispatch fee instead.
No. Membership does not cover dispatch fees, diagnostic time or after-hours charges. Club members get priority scheduling, discounted repair rates and a yearly tune-up, which is the best way to avoid a night-time breakdown (membership plans).
