When the chill sets in across Modesto and the Central Valley, your heating system becomes the heart of your home’s comfort. But what happens when it starts acting up? At Comfort Experts Heating & Air Conditioning, we know how frustrating it can be to deal with heating issues—especially when temperatures dip. That’s why we’ve put together a guide to help you identify and troubleshoot some of the most common heating problems before calling in the pros.
1. No Heat at All
One of the most obvious signs of trouble is a complete lack of heat. First, check your thermostat settings to ensure it's on “heat” and set to the correct temperature. If it is, but your furnace still won’t kick on, the issue could be with the pilot light (for older systems), a tripped circuit breaker, or a faulty thermostat. If you’ve ruled those out, it’s time to call Comfort Experts Heating & Air Conditioning for a professional diagnosis.
2. Uneven Heating
If some rooms in your home are toasty while others are cold, your system may be struggling with airflow. This could be due to clogged air filters, closed or blocked vents, or issues with ductwork. Try changing your air filter and checking that all vents are open and unobstructed. If the problem persists, you may need an airflow assessment from our heating experts.
3. Strange Noises
Rattling, banging, or screeching sounds coming from your furnace are signs something isn’t right. These noises could indicate anything from a loose belt or broken blower motor to a cracked heat exchanger. Loud or unusual sounds should never be ignored—call our trained technicians at Comfort Experts Heating & Air Conditioning to inspect and repair your system before it becomes a bigger issue.
4. Short Cycling
Short cycling happens when your furnace turns on and off frequently without completing a full heating cycle. This can wear down your system and reduce efficiency. Common causes include dirty air filters, thermostat malfunctions, or an oversized system. A quick inspection by a professional can pinpoint the problem and get your system running smoothly again.
5. Furnace Blowing Cold Air
If your furnace is running but the air coming out is cold, check the thermostat settings and air filter. In some cases, your pilot light or ignition system may be faulty, or the burner may be dirty. Our certified team at Comfort Experts Heating & Air Conditioning can safely address these issues and restore your home’s comfort fast.
