A furnace that doesn’t heat your home properly is more than just an inconvenience. It can leave you uncomfortable during Boise’s cold winters. Before you rush into calling a professional, it’s important to understand some common reasons why this might be happening and how you can address them. Here’s what you need to know.
Step 1: Check the Thermostat Settings
One of the easiest things to check when your furnace isn’t heating properly is the thermostat. If the settings aren’t right, the furnace may not be receiving the right signals to turn on and heat your home. A malfunctioning thermostat could also be a sign that your HVAC in Boise needs a thorough inspection.
Solution:
- Make sure the thermostat is set to “Heat” mode and the temperature is set higher than the current room temperature.
- If you have a programmable thermostat, check that it’s not set to an incorrect schedule.
- If the thermostat seems unresponsive or inaccurate, it may be time to replace it or have it calibrated.
Step 2: Examine Your Air Filters
Dirty air filters are a common cause of furnace malfunctions. When filters are clogged, they prevent proper airflow, which can cause your furnace to overheat and shut down. Poor airflow can also reduce the efficiency of the system, making it work harder than it should.
Solution:
- Check your air filters and replace them if they appear dirty or clogged.
- For optimal furnace performance, it’s recommended to replace filters every 1-3 months.
- Regular filter maintenance can help improve air circulation and extend the life of your furnace.
Step 3: Inspect the Pilot Light or Ignition System
Older furnaces rely on a pilot light to ignite the burners. If the pilot light goes out, your furnace won’t be able to heat your home. More modern furnaces use electronic ignition systems that may fail due to faulty components or electrical issues.
Solution:
- If your appliance comes with a pilot light, verify whether it’s on and glowing. If it’s out, follow the manufacturer’s guidelines to safely light it again.
- If the pilot light keeps going out, you may have a problem with the thermocouple, which may need replacement.
- For newer furnaces with electronic ignition, a professional technician can diagnose and fix any ignition-related problems.
Step 4: Assess the Blower Motor
The blower motor is responsible for pushing the heated air through the ducts and into your home. If the motor isn’t working properly, it could be a major reason why your furnace isn’t providing enough heat.
Solution:
- Listen for any unusual noises from the blower motor.
- If the blower motor is working intermittently or isn’t running at all, it could be due to an electrical issue or mechanical failure.
- Have a professional technician inspect and repair the motor if necessary.
Step 5: Check for Duct Leaks
Leaky ducts can significantly reduce your furnace’s heating efficiency. If warm air is escaping from the ducts before it reaches the rooms, it can leave your home feeling cold even when your furnace is running.
Solution:
- Inspect your ducts for visible cracks or leaks.
- Seal any leaks with duct tape or an appropriate sealing material.
- You may also want to have your ducts professionally cleaned and sealed to ensure maximum efficiency.
