During the wintertime, your furnace is working hard in order to keep your home comfortable. Even with proper preventive maintenance and a seasonal checkup, there is a chance that your furnace could develop a problem. If you notice any of these symptoms, it is important to call your heating service technician for a repair or maintenance visit.

Furnace Maintenance

Strange Smells

In some cases, a furnace that is not operating properly will release strange smells into your home. If you smell an odor of rotten eggs, leave your home and call for an emergency repair. The smell of rotten eggs means that there is a gas leak. Furnaces can also make some other smells that suggest a repair is needed. A rubbery smell means that the furnace could need a new belt, while a burned dust or hair smell suggests that a new air filter may be needed.

Loud or Unusual Sounds

When a furnace is working correctly, the sounds it makes are similar to a soft humming or whirring of the fan. On occasion, you may hear a few clicks as the air handler turns on and off. Loud banging or clanging sounds are not normal for a well-functioning furnace. Grinding sounds are also not typical of a furnace. If you hear any pops, bangs or other unusual or loud sounds from your furnace during a heating cycle, it is time to arrange for a furnace repair or maintenance.

Poor Climate Control

Furnaces are highly dependable and provide you with 20 to 25 years of heating during the cold winter months of the year. As a furnace wears out or when a component breaks, you may notice certain problems with indoor comfort and climate control. Some of these issues include:

  • Cold air blowing from the vents
  • Indoor temperature does not reach the level on the thermostat
  • Air that is dusty
  • Indoor humidity levels that drop below 30 percent

Increase in Breathing Trouble

One of the most important parts of your furnace is its air filter. The air filter is responsible for capturing tiny particles so that they are not blown into the living spaces of your home. A dirty or damaged air filter allows all of the allergens to get into the air that you breathe. If you notice an increase in sniffles or sneezes, wheezing, coughs, asthma or colds, a dirty furnace filter could be the culprit. Helpful heating system technicians install new high efficiency particulate air (HEPA) and other great air filters with high minimum efficiency reporting value (MERV) ratings to help keep your home’s air as clean and healthy as possible.
