No heat? Check these first
- Check the thermostat. Make sure it is set to Heat, set 3 to 5 degrees above room temperature, and has fresh batteries.
- Check the power. Make sure the furnace switch near the unit is on and the breaker is not tripped. Reset a tripped breaker once. If it trips again, call us.
- Check the air filter. A clogged filter can overheat the furnace and trip a safety switch. Replace it if it looks gray or packed with dust.
- Check the furnace door and drain line. The front panel must be fully closed, and a clogged condensate drain can shut down a high-efficiency furnace.
- Look for a blinking light. Write down the blink code on the control board. It helps our technician find the problem faster.
Smell gas? Leave the home first, then call your gas utility or 911 from outside. If your carbon monoxide alarm sounds, get everyone out and call 911.
Signs you need emergency HVAC repair
- No heat and the house is getting cold, especially near freezing.
- The furnace starts and stops every few minutes and never warms the house.
- A burning or electrical smell that does not fade after a few minutes.
- The breaker for the furnace or heat pump trips again after you reset it.
- Water pooling around the furnace or air handler.
- The heat pump outdoor unit stays covered in ice or its fan will not spin.
What to expect when you call
When you call 425-201-1998, tell us what the system is doing and whether anyone in the home is very young, elderly or sick. We answer after-hours calls and schedule the earliest visit we can. On site, the technician diagnoses the problem first and gives you the price before any work starts.
If a repair gets the heat back on safely, we make it. If the system is unsafe, such as a furnace with a cracked heat exchanger, we shut it down, explain why and show you your options. Financing is available on new systems. For problems that are not urgent, our $49 HVAC diagnostic and maintenance visit is the best place to start.

Emergency HVAC questions
What should I do if my heat goes out?
