Falling Temps and Your Heating System

By Austin Heyen, Head of Aurora’s HVAC Division

Is your heating system ready for the eventual cooling temps? The best way to start the pre-season inspection process is to turn on your heating system. Set the thermostat to a degree that is higher than your home’s current temperature, and wait for your unit to release warm air. If your heating system doesn’t emit heated air or your home’s temperature doesn’t rise to the degree on your thermostat, call your trusted HVAC technician for help.

Changing Filters

A system that does not emit warm air could be a symptom of a more serious problem. The solution could be as simple as changing a dirty air filter or igniting a pilot light, or you may need a professional to clear a blockage or repair ductwork. Dirty air filters cause your heating and cooling unit to work extra hard and that could lead to overheating and costly system failures. According to leading HVAC manufacturers, you should change your HVAC air filter every 90 days. If you have pets or live in an area that has construction activity, you will want to change your system’s filter every 60 days. When you are performing a pre-season inspection of your heating system, it is best to replace the air filter to avoid problems later in the season.

Vents and Registers

Vents and registers help to circulate warm air throughout your home and can be the cause of unsafe and inefficient HVAC operations when they are not properly maintained. Dirty vents that contain dust, pet dander, and other contaminants lower indoor air quality.  To prevent indoor air pollution, dust and vacuum your vents and registers. If your system’s ducts have not been cleaned in several years, call for professional help. Having your ductwork cleaned gives you peace of mind that your indoor air is as clean as possible and that your HVAC unit will not have a premature breakdown in the middle of winter due to negligence.

Unusual Noises

When you turn on your heating system after it has been idle all summer, you will want to listen for any unusual sounds. Some rattling noises that come from your HVAC unit are signals that components are loose. Your heating system could let you know that it is having some ignition problems if you hear a booming noise. Grinding sounds indicate motor issues, and thumping noises mean that one or more components are off balance. Strange noises that do not go away within a few minutes of system start are signals that you need to schedule a service appointment. 

System Maintenance

Industry experts agree that you should have your heating and cooling system inspected and serviced every year. Fall is the perfect time to have your heating system checked out. Evaluating your HVAC unit’s controls is part of the 25-point HVAC inspection that licensed HVAC technicians perform during annual service calls. These professionals check whether your unit turns on and off properly. They also test your system to see if your thermostat is working normally. If there is a problem with your heating unit’s controls or thermostat, it could mean that there are loose electrical connections. That is okay because your HVAC technician will check for those issues as well.  Give us a call at Aurora Plumbing, Electrical, Heating, and Cooling and we will make sure your heating system is ready for colder temperatures, 701-242-7202.
