  • Heats air and distributes it via duct-work
  • Doesn't heat as evenly as boilers
  • Fueled by gas or electricity
  • Can last 15-20 years on average
  • Common in modern homes
  • Fairly inexpensive/easy to install and maintain

Common Furnace Repair

  1. Cracked Heat Exchanger – This pricey repair can be prevented with regular maintenance. This part is important because it separates the combustion process from the breathing air in your furnace.
  2. Dirty Filters – If you want your furnace to run efficiently then you’ll want to make sure your filters are cleaned or replaced regularly. 
  3. Slipped or Frayed Blower Belt – If you hear a high-pitched squeal then it might be the belt. The blower moves the warm air throughout the house, thus if the belt goes then the air isn’t being distributed.
  4. Electric Ignition or Pilot Light Control Problems – The ignition of pilot light is the heating element of the furnace, so if you notice a drop in heat you might need a professional to look at this.
  5. Malfunctioning Thermostat – If your thermostat is malfunctioning  it can mess with the fan and comfort levels of your home so if you notice anything off about it be sure to call for help.
  6. Worn Out Ball Bearings – Usually signified by a scraping sound, if you hear this you’ll want to turn off the furnace and call an HVAC expert right away.

  • Heats fluids then distrubutes it via pipes
  • Radiates heat evenly
  • Fueled by natural gas, propane, oil or wood
  • Can last 15-20 years on average
  • Common in older homes
  • Installing one is going to be more complex and costly

Common Boiler Repair

  1. Leaks – Since boilers are designed to be airtight, any leaking is a severe issue. The source of the leak must be found, repaired and the lost water replaced right away.
  2. Low Water Pressure – Listen for any rumbling sounds because it is a sign of overheating. Leaving your system like this can cause extensive and pricey repairs.
  3. Corroded Parts – Rust sometimes can get into the boiler and usually means it needs to be replaced. This problem can be limited by regular maintence.
  4. Broken Circulator Pump – If your heat seems to have stopped but the boiler still seems to be running then the issue is likely the circulator pump. This is a common and fairly easy job for professional HVAC service providers.
  5. Dirty Tanks – Every now and then the water in the boiler gets dirty with sediment and needs to be replaced with clean water. Regular cleaning keepts the efficancy up in your boiler.
  6. Burnt-Out Heating Element – In electric boilers there are two heating elements that warm the water inside the tank. If one goes then the temperature will drop, and thus the element will need to be replaced.
