A furnace always comes in handy when you badly need extra warmth during the cold season. It can be frustrating when your furnace malfunctions and can't serve your household as it should.
While you might need to replace your furnace when it incurs damage beyond repair, you can fix some problems and continue enjoying a warm home.
Check your furnace for any of the following problems and hire a furnace repair expert to fix the unit.
1. Unusually Strong Smells
If you have a gas-powered furnace, it's common to smell gas every time you start your furnace. However, if the smell is more pungent than usual and lasts more, your furnace needs repair. The smell could be from a gas leak or too much dust in your furnace.
You can also tell a broken electric-powered furnace with the unpleasant smell of burnt plastic components. If you've had recent power surges in your home, your furnace might have paid the ultimate price hence the smell of burnt plastic and wires.
You should call a furnace repairs expert once you detect unusual lingering smells from your furnace. The expert will assess your furnace and repair it accordingly.
2. Inadequate Heat From The Furnace
A furnace should heat a room or home comfortably, depending on the unit's size and capability. If it fails at its job, that should be your cue to call a heating repair expert.
The expert should confirm why your furnace stopped producing heat. Some of the common reasons include the following:
- A dirty or clogged air filter
- Open return and supply air ducts
- An open blower door
- Blocked vent pipes
- Blocked drain pipes
Furnace repair experts are knowledgeable and can fix most common furnace problems. However, if the furnace has extensive damage, the expert might advise you to replace the unit with a new one.
3. Persistent Unusual Noises
Furnaces are generally noisy, but you get used to the noise with time. However, loud, persistent, and disruptive noises from your furnace is a cause for alarm. Most times, the loud noise indicates a broken part in the furnace.
Some of the common causes of loud furnace noses include:
- Broken blower wheel or motor
- Loose panels or doors
- A cracked heat exchanger
Listen carefully to the noise from your furnace, and explain it to the repair expert when inspecting the unit.
4. Dirt and Dust in the Air
While the dirt and dust in your home could blow in from outside, a malfunctioning furnace can also blow in dust in the air. A faulty furnace can blow in bacteria, dust, and other allergy-triggering particles and reduce air quality in your home.
If you or someone in your home is allergic to dust, you'll experience itchiness, watery eyes, coughs, colds, and headaches.
Check the area around the furnace when you turn on the unit. If you notice dust swirls in the air, you know you need to repair your furnace.
Most times, you can correct this problem by replacing the air filter. However, if your furnace has clogged ducts, you'll need a furnace repair professional to fix your unit.
