Is your heating system not quite working like it used to? Leaving a problem with your furnace untreated could lead to rising energy bills as your furnace becomes inefficient at heating your home. It could also result in costly repairs as the problem worsens over time. If you notice a problem with your furnace, then it’s better to call the professionals sooner rather than later. Having your furnace regularly maintained can help to significantly lower your bills.

Here are a few common furnace problems you might face and what to do about them.

Cold air coming from the vents

If your heating system suddenly starts blasting cold air from its vents, then you could be left shivering. There are a few possible causes behind this problem. Firstly, make sure your thermostat is set to the correct setting and temperature. You can also check that your air filters are clear. Dirty and blocked air filters can cause your HVAC system to run inefficiently or even overheat. Make sure you change your air filters on a regular basis.

If neither of these are the problem, then you should call for HVAC repair. It may be faulty ductwork or a damaged part that is causing cold air to be expelled, so your HVAC system should be inspected by a professional.

Unusual noises when you turn your furnace on

If you hear banging or rattling when you first turn your furnace on, then it could be caused by a build-up of gas when igniting your furnace. As this can be a dangerous problem, you should call a repair technician. This issue may be a result of a faulty ignitor or a build up of dust around your burner.

Noises while your furnace is running

Your furnace shouldn’t run noisily, either. If you hear scraping sounds while it is heating your home, the blower wheel or another part may have come loose, causing it to scrape against other parts of the furnace. In this case, you should switch off your heating system and call for HVAC repair. Unusual noises could also occur when parts need lubricating, which is a quick and easy fix for a professional.

Switching on and off

If your furnace turns on and off randomly and when it shouldn’t do, and if you’re sure that your thermostat is set correctly, then there may be a fault with the thermostat itself. Call AC Express to properly diagnose the problem with your furnace or thermostat.
