Learn to Recognize These Common HVAC Warning Signs

When it comes to keeping your home comfortable, your HVAC system has is essential. Like any other major appliance in your home, your HVAC system will start to wear out over time. Keep an eye out for these warning signs that will help you know it’s time to repair or replace your system.

Higher Energy Bills

Unless your utility company has recently gotten a big rate hike, your energy costs should stay relatively stable on a year-to-year basis. One sign that your HVAC system needs some maintenance is a sudden spike in the cost it takes to operate it. There could be a one-month spike because of a really hot month, but if you see a bump in your energy costs that lasts for a longer period of time, you'll want to have a professional look at your system.

Uneven Temperatures

If your HVAC is running effectively, you should have a fairly stable temperature when you walk from one room to another. If the room next to your unit is cool and another room further away is unusually warm, a faulty system might be the culprit. Your HVAC should have the power to heat or cool every room in your house fairly evenly.

Odd Smells

Your HVAC system could emit some strange smells if it's not working correctly. Some odd smells are actually quite common and might be a sign of mold or mildew in your ductwork. Another common smell is the smell of burning dust—this usually happens when you first turn on your furnace in the fall. However, if this burning smell continues beyond the first few days after turning your system on, you'll want to get it checked out.
