Think It’s Finally Time for a New Furnace?
Frequent repairs can be a key indicator that replacement is necessary. If maintenance and repair costs are adding up, upgrading to a new system may be a more cost-effective solution. If any of the following are causing you regular stress, your furnace may be nearing the end.
Cold Air Blowing
What’s worse than cool air blowing from the heating vents on a frigid winter morning? An unreliable furnace can mean it’s time to consider a modern update.
Strange Odors
If you smel burning or other strange odord eminating from the heating vents of the furnace, it’s important to have the system checked immediately. Contact Fast Heating & Air for a same-day service call.
Uneven Heating
If some rooms are warm and others are cold, it could be an indication the furnace is no longer capable of heating the full house, or incorrect ductwork is making the task overly challenging for the furnace.

If the furnace frequently starts and stops, this could be an indicator of overheating, pressure switch issues or flame sensor issues. On older furnaces, a weak pilot light can also cause this to occur.
