Lennox SLO185V Variable-Speed Oil Furnace

One of the things that cause stress to homeowners is an underperforming furnace, especially during winter. No one would want to deal with an inefficient furnace that is unable to provide you the warmth and comfort you need. Thankfully, when furnaces start losing their efficiency, they will display obvious signs.

If you have to turn your thermostat higher and higher to heat your home but it doesn’t make much of a difference, it shows that your furnace is due for a repair. This is a sign that your thermostat lacks the ability to properly circulate the air to keep your home comfortable.

It is quite normal for a furnace to produce a little bit of noise when you turn them on or off, but if the sound starts to get considerably louder, your unit may need replacing. These noises indicate problems in certain components of your furnace. For example, if you hear popping sounds, it may be because of a delayed rough ignition due to dirty burners or a loose or dirty filter getting pulled against its frame, or a loose blower door. If you hear a rattling noise, it may be due to unsecured ductwork, loose screws or sheet metal. It may also mean the blower motor is not properly balanced.

In addition, if you notice a steady rise in your utility bills without a comparable increase in use, consider replacing your furnace. The amount of money you save in the long run can help you pay for a new, more efficient heating system.
