Blue is what the color of the flame if your furnace is working correctly. Other colors such as yellow is not correct. There is probably a leak, and this will most definitely need attention. Don’t wait to call us on this one; we will be right out!


Not heating evenly

If the heat is not uniformly dispersed throughout your house, it could mean many different things. It could mean that there are issues with the duct work or it could be a circulation problem. If however you are turning up the thermostat and nothing is happening it could mean a short in the system and will need attention.


Does your furnace sound like it belongs in a scary movie?

If your furnace is making strange noises it probably isn’t possessed, we just need to do some maintenance to find out the cause. Keep in mind that the sound will not go away on their own, you’re going to need a little help from us, we will take care of any necessary exorcism.

If you have a gut feeling that something is not right, follow that instinct and give us a call to check things out for you.
