10 Furnace Failures
1. Cracked Heat Exchanger
~ Can be prevented with regularly scheduled maintenance
2. Dirty Filters
~ When filters accumulate dirt, the furnace will work harder. This can lead to
higher energy cost. Filters should be changed about every 30 days.
3. Frayed Blower Belt
~ Do you hear a squeal? Call Porcellini HVAC to have this replaced and fixed.
4. Faulty Pilot
~ This will lead to a reduction in the heat getting into your home.
5. Thermostat Malfunctioning
~ This could lead to issue with the fan and your comfort levels.
6. Yellow Colored Pilot or Flickering
~ It’s possible there is excessive carbon monoxide in a gas furnace.
7. Ball Bearing Issues
~ Do you hear a scraping sound? Turn off the furnace and call Porcellini HVAC
Services at 302-507-5777.
8. “Short Cycling”
~ Filters could be clogged causing air flow to be restricted or there is a thermostat
9. Limit Switch
~ Furnace blower stays running. Call Porcellini HVAC Services at 302.507.5777
10. Mechanical Problems
