It’s easy to tell when your home’s heating system is broken. Even in warmer places like Nacogdoches, Texas, you’ll notice if your furnace or heat pump completely stops working when it’s chilly outside. But how you do you know when your HVAC system just needs maintenance? If you see these signs, call a reputable service company to schedule repairs.

Dirt and Dust

Changing air filters regularly is part of important routine maintenance for every homeowner, especially if you have children with asthma or allergies. Systems have to work harder to push air through clogged filters, which can cause mechanical issues. Take note of how often you change the filter and its condition. If you notice particularly dirty filters even though you change them often, your system may need repair. Also, extra dust around the house can signal clogged filters or leaking ducts.

Big Bills

Your utility bills can give you clues as to how efficiently your system is operating. A gradual increase in energy usage or a sudden spike in your bill may require a call to a professional. Service may be necessary, or the system may be old and need to be replaced.

Inconsistent Air Flow

Temperatures inside a home can vary because of inadequate insulation or the number and placement of windows, but big differences in temperature from room to room may mean your heating system needs repair. Problems include equipment malfunction and issues with ductwork.

Bumps and Bangs

While no heating system is entirely silent, you shouldn’t hear loud or constant noises such as rattling, banging, or popping. Improperly installed ducts that sag or bend can become noisy because of obstructed air flow. Closing too many dampers at one time can also make systems become loud.

Routine maintenance on HVAC systems is key to keeping your home comfortable, improving indoor air quality, and reducing energy bills. If your heating system needs repair, call McWilliams Heating, Cooling and Plumbing at (877) 936-1974.
