Furnace Making Strange Sound  

All HVAC systems have fans, which work to circulate the air throughout your home. The sound it makes is something to pay attention to, and you should consider upgrading if you hear something different. If you notice an unusual sound coming from your system, it might be time to contact a furnace diagnostics company for a checkup to find out what is causing this issue.  

Worn Down Filters 

One way to keep your HVAC system running smoothly is to use good filters. Maintaining the air in your home is crucial to energy efficiency and comfort, so you should always have good filters on hand. If you notice your filters are getting worn down or they aren't working as well as they should be, it's time to replace them with new ones. 

Sooty Odor 

Even if your system is functioning properly, you want to look at all of your HVAC system components closely. A big, sooty smell is one of the most obvious signs that something isn't working correctly. If you notice this type of odor coming from your vents or outdoor units, it might be time to replace them with new ones. This will help you maintain the efficiency and comfort of your HVAC system. 

High Energy Bills  

If your bills are out of control, it's time to troubleshoot the issue. To ensure your home stays cool, it is important to have enough insulation in all rooms, especially the attic. If you can't afford your heating and cooling bills, something may be wrong and should be fixed as soon as possible.
