Furnace Troubleshooting FAQs with AirPoint Expertise

Generally, it's recommended to replace or clean your furnace filter every 90 days or three months. However, this can vary based on the filter type, furnace usage, and environmental factors like pet dander or high dust levels. If you have pets or allergies, consider checking and replacing the filter more frequently.

Yes, a faulty thermostat can lead to heating issues. If the thermostat isn't calibrated correctly, it may not signal the furnace to turn on or off at the appropriate times, leading to inadequate heating or overworking the furnace. If you suspect thermostat issues, check its settings and batteries. If the problem persists, it might need professional recalibration or replacement.

Signs of mechanical wear in a furnace include unusual noises (like banging, whistling, or grinding), reduced heating efficiency, frequent cycling on and off, and the presence of unusual odors. Physical signs, such as rust or soot around the furnace, can also indicate wear. Regular maintenance is key to addressing wear before it leads to more significant issues.

Consider replacing your furnace if it's over 15-20 years old, requires frequent and costly repairs, or is no longer efficient (leading to increased energy bills). Other indicators include inconsistent heating and the inability to keep up with your home's heating needs. Upgrading to a newer, more efficient model can be more cost-effective in the long run.
