What To Do If Your Heater Is Not Working

If you notice that your heat has suddenly stopped working, you might wonder if there is a problem with your furnace. It may be something simple you can take care of on your own, or you may need to bring in a professional if it is a more serious problem.

The first thing to do when your house gets cold is to check for simple problems with a simple solution. When you suspect the furnace has gone out, take these steps:

  • Make sure your furnace is turned on. Most furnaces have a switch mounted on their side (it may look like a light switch) that can be easily bumped. Turn it back on and see if that fixes the problem.
  • Make sure your furnace is set to “heat mode” on the thermostat. If not, set it to “heat” and wait to see if your home starts to get warmer.
  • Reset your furnace. Find the switch mounted on or near the furnace and turn the power off. If you can’t find a switch at the furnace you can turn off the circuit breaker to the furnace at the main circuit breaker box. Wait about 10 seconds. Turn the switch or breaker back on and check the furnace to see that it has power again.
  • Check your thermostat to make sure some other setting wasn’t accidentally bumped or changed. If you have a smart thermostat, it might have an alert about a potential problem with your furnace.
  • Check if your thermostat may be broken. Set it to different temperatures and see how the temperature in your home responds.
  • Check your digital thermostat batteries. Most thermostats will display a low battery warning. If the batteries die completely, the thermostat will stop working and your furnace won’t function.
  • Check your electrical panel to make sure you didn’t blow a fuse or trip a breaker. You can fix these at home.
  • Make sure that the pilot light isn’t out or that the gas valve is not shut off. If it is, you can relight the pilot light.

If none of these seem to be causing the problem with your furnace, or if you feel uncomfortable dealing with them on your own, contact the team at Design Aire!

Furnace Repair vs Replacement

If you are experiencing a furnace problem, our technicians can perform an inspection on your broken furnace to determine what the root cause of the issue is and help you decide if it makes more sense to repair or replace your unit. A good rule of thumb is that once your heater repair costs exceed half the cost of a new unit, it’s time to replace your furnace.

How To Heat Your House When Your Furnace Breaks

Along with dressing in layers, putting on your winter gear, and wrapping up in blankets, here are some other things you can do to help keep your home as warm as possible until your furnace can be fixed.

Use a Space Heater

If a power outage wasn’t the cause of your furnace going out, use a space heater to stay warm. Place it in a central room on a level, flat surface and try to stay there with your family most of the day until your furnace is up and running again. Having everyone gathered together in one room will keep all of you warmer. Don’t sit on or drape anything over it and be sure not to leave it unattended.

Use Your Fireplace

If you have a gas or wood-burning fireplace, use it to warm up parts of your home. Be sure to use all safety precautions when starting a fire in your fireplace.

Cook or Bake Something

You should never turn on the stove or oven by itself for the purpose of warming up your house — that is a dangerous fire hazard. However, you can pass the time by cooking or baking something and help warm up your kitchen in the process. Try a recipe for something that can keep you warm like soup, cookies, pie, bread, or a casserole!

Insulate Against Outside Air

To prevent cold, outside air from getting inside, keep your windows and doors closed. Shut the blinds, curtains, and drapes or hang towels over windows that don’t have a window treatment. Close doors to rooms you aren’t using, such as the basement or guest rooms. If your family is able to stick to one room until it warms up, hang up blankets in the doorway to try to keep the room as warm as possible.

Stay Inside

Every time you open the door, heat escapes and cold air comes inside. Try to limit the number of times you go out and come back in. Consider having everyone stay inside until your furnace is back up and running.

Will My Pipes Freeze?

Many people worry about their pipes freezing as their home gets cold after their furnace breaks. This is definitely a concern — going without heat for even a few hours can cause your pipes to freeze. Along with taking steps to keep your house warm, you can do these tasks to reduce the risk of frozen and burst pipes:

  • Turn the faucets on to keep the water running on a low drip
  • Place space heaters where pipes are vulnerable, such as in the basement (but do not leave them unattended)
  • Open cabinets, closets, and other spaces that contain plumbing to circulate warm air

The installation team arrived on time and went right to work.They worked with confidence and professionalism.We appreciated the care in protecting our floors and even the choice of how they went up on the roof indicated that they really did care. This company did what they said they would and certainly has our vote of appreciation and gratitude. We will happily recommend Design Aire to anyone.

Ken L.

One of the best companies to work with. My own profession is in a service industry and so I very much appreciate all the positive things about Design Aire.
The install crew arrived right on time and took exactly how much time they said they would to complete the job. The work was done well, the crew cleaned up after themselves, and were very pleasant. Seth in the office was extremely in-tune to our needs and very responsive.
I would highly recommend Design Aire.

Maddy R.

I was very impressed with Design Aire. They were timely and did an outstanding job with the installation of my new furnace. They had great communication and went above and beyond. I would highly recommend them to friends and family. Thank you so much Seth and Design Aire for making this an effortless transaction. VERY PLEASED!

Jonny M.

Design Aire sent a salesman to plan the system, and just a couple of days later sent the installers to remove the old system and install the new one. Everything happened when they said it would and the system performs as they said it would. All of the Design Aire staff were courteous, the work was performed efficiently and neatly, and they left the area cleaner than they found it. This is the second unit Design Aire has installed for us, and I have no need to look elsewhere.
