Signs You Need to Schedule Furnace Repair

Is cold air coming out of your vents while your furnace is running? Usually it's fairly obvious when something is awry with your home's heating system, but other times the signals are more subtle. Be on the lookout for the following indications that something is wrong with your furnace.

How to tell if your furnace is broken:

  • Sudden spike in utility bill - it's normal for gas or electric bills (depending on what type of furnace you have) to go up during the winter months when you are using your home's heating system more frequently. However, if the spike is surging past the bounds of normal, you may consider calling a professional HVAC technician to come take a look.
  • Strange smells - usually it will smell a little bit dusty when your furnace kicks on for the first time of the cold weather season, but if you smell a sulfur-like odor you might have a gas leak. If you suspect a gas leak leave the building immediately, leave the door open, and call your gas company to report the leak.
  • Loud noises - if you hear any loud noises while running your furnace, that is a clear indication that something is wrong. Be on the lookout for banging, popping, or grinding noises as your furnace is running, and call Air Treatment Company right away.

How to Troubleshoot a Furnace that's Blowing Cold Air

A furnace that isn't blowing warm air clearly isn't doing it's job. If you're having this problem and trying to troubleshoot, here are some things that may be causing the issue:

  • No Fuel. Furnaces depend on fuel in order to run. When there is no fuel in your furnace and the furnace is turned on, it will only blow out cold air. If you have a gas furnace, check the pilot light. If you have an electric furnace, make sure that your electric breakers are in the on position.
  • Clogged Air Filters. If your furnace is blowing out cold air, a dirty air filter could be to blame. A clogged air filter will only inhibit airflow, which also leads to heat loss. Changing your air filters once a month or as needed is a must.
  • Broken Duct Work. Duct work takes the heat from your furnace and distributes it to the rooms in your home. However, if your duct work is damaged, it will be carrying cold air to each room. If you suspect that your duct work has holes in it, have it patched up by a professional.

Things to Consider When Buying a New Furnace

Are your heating bills unreasonably high? Your old furnace is probably burning your money away. If that is the case, it might be time to purchase a new one. With so many choices on the market today, it can be hard to make a selection. Below are some key points that will help you narrow down the search for the perfect furnace.


When it comes to furnaces, size matters. If you have a large house and a small furnace, it will have a hard time warming your house effectively. It will end up using more electricity in order to make it to all areas of your home. In return, this drives up the cost of your utility bill. Only a properly sized air conditioning unit will effectively warm your home.

Energy Efficiency

A new furnace is bound to be more energy efficient than an older model. In fact, all new furnaces on the market today come with an Energy Label Guide. This is a helpful tool that displays the annual energy costs.

The Price Tag

As with any purchase or investment, it is important to have a realistic budget in mind. Investing a decent amount of money in a furnace could save you money on your utility bills in the long run.
