After months of relying on your air conditioning to beat the heat, the first crisp days of fall signal it’s time to switch to heating. But turning on your furnace or heat pump after a long summer break can sometimes reveal hidden issues. Fortunately, with a little preparation, you can avoid many of the most common heating problems and enjoy a warm, trouble-free fall and winter. With this in mind, we at LV Heating & Cooling would like to discuss how to avoid the heating issues that can spring early in needing the heating season.
Schedule a Pre-Season Heating Inspection
One of the best ways to avoid heating issues is to schedule a professional tune-up before you even turn your system on. During the summer, dust, debris, and even small animals can find their way into the components of your heating system. A licensed HVAC technician can inspect, clean, and test your system to ensure everything is working correctly. Catching minor issues early prevents them from turning into major, costly breakdowns.
Replace or Clean the Air Filter
Your HVAC air filter affects both cooling and heating performance. If you haven’t changed it since the beginning or middle of summer, it’s likely clogged with dust and allergens. A dirty filter restricts airflow, forces your system to work harder, and can lead to overheating and breakdowns. Replace your filter at the start of the heating season and continue checking it every 1–3 months.
Test the Thermostat Early
Don’t wait for a cold snap to discover that your thermostat isn’t working properly. Before you really need your heat, switch your thermostat to heating mode and raise the temperature a few degrees. If your system doesn’t respond, you may need to recalibrate or replace your thermostat. Upgrading to a programmable or smart thermostat can also help reduce energy waste during the colder months.
Inspect Vents & Ductwork
Blocked vents and leaky ducts can cause uneven heating, poor indoor air quality, and increased energy bills. Before turning on your heat, check that all vents are open and unobstructed by furniture or curtains. If your home still feels drafty or certain rooms don’t warm up properly, have your ducts inspected for leaks, blockages, or damage.
Watch for Strange Smells or Noises
It’s common to smell a slight burning odor when you first turn on your heat, usually, it’s just dust burning off the heating elements. However, if the smell lingers or you hear unusual sounds like banging, squealing, or grinding, shut the system down and call a professional. These signs can indicate electrical problems, a failing blower motor, or loose components.
Check the Pilot Light or Ignition System
If your heating system uses a pilot light or electronic ignition, test it early in the season. A weak flame, difficulty igniting, or frequent shutdowns may signal a problem with the thermocouple, ignition sensor, or gas supply.
Stay Ahead of Heating Problems
Taking proactive steps now can prevent heating emergencies in the middle of winter. A quick inspection, some basic maintenance, and early testing will go a long way toward ensuring your system operates smoothly after a long summer hiatus. Don’t wait until it’s freezing, make sure your heat is ready before you need it. Call LV Heating & Cooling when you cooling and heating services, especially to prepare for the colder weather.
