Plumber fixing a gas furnaceWinter is fast approaching, and the unbearably cold nights and days are about to set in. The days are getting shorter, and the weatherman is predicting a colder-than-usual winter. It is the ideal time to ensure that your furnace is in great shape. Otherwise, it may not get you through winter. Here is how to know if you require a new heater:

1. Your Energy Bills Are Unbelievably High

Considering that the furnace is one of the electronic devices that require a lot of energy in the house, its consumption affects your energy bills considerably. Therefore, when the household energy consumption skyrockets, the furnace is likely to be the culprit. There is a chance that it requires some few repairs, and it can be that you need to change it. For both repairs and replacement, consider hiring reputable HVAC contractors in Knoxville, TN.

2. There Is Too Much Dust in the House

If you have been doing your best to contain the dust in your house but cannot seem to make any significant stride, it is possible that your furnace is letting you down. The heater should remove airborne particles from the warm air. Start by inspecting the furnace filters and clean them. If the issue persists, consider replacing the furnace.

3. You Hear Strange Noises

A furnace that makes odd noises requires repair or replacement. If you have had the heater for more than 15 years, replacement is the best option. Older furnaces usually make banging, squealing, popping, and rattling sounds. The noises are an indication of a faulty system.

4. The Rooms in Your House Have Varying Temperatures

One sign of an inefficient furnace is some rooms being warmer or colder than others. The probable cause is a duct system incapable of distributing heat evenly in the house. As such, your furnace may require replacing.

Even after you notice these signs, there is only so much that you can do. Therefore, when it is time for an upgrade, contact HVAC experts to fix or replace the furnace. The benefits of restoring an old heater are immense, from energy efficiency to warm winters.
