With luck, you’ll never need the information in this article. Your furnace will perform admirably all winter, keeping you and your family warm.
But if you do have furnace issues, it helps to be ready and informed. In this blog post we’ll look at some issues you might want to watch out for, while also discussing the benefits of the Mitsubishi Electric heating and cooling system.
1. A noisy furnace
Not all noises are a sign of a serious problem. In some cases, it might just be air moving through uninsulated ductwork.
Different noises can signal different issues. For example, popping or pinging sounds could be our ducts expanding and contracting with hot or cool air. Rattling can indicate you have loose panels that need to be tightened.
If you hear a squealing sound, you may have a belt that’s loose or needs to be replaced, while grinding noises signal motor bearings in need of repair (you’ll need a repair technician here).
In fact, we’d argue that any noises warrant investigation by an HVAC professional. Something that isn’t a serious problem now might turn into a larger – and more expensive – issue down the road.
2. Your furnace is rapidly turning on and off
There might be a lot of reasons why your furnace comes on and shuts off in quick succession. One of the most common is a dirty or worn-out air filter. Older filters can put a strain on your system and eventually lead to mechanical failure. If you haven’t replaced the filter in a while, now is the time to do that.
If a new filter doesn’t do the trick, you might have a more serious HVAC issue, possibly with the blower motor and belts, which means a call to your local HVAC professional.
We should also note that the inverter inside the Mitsubishi Electric heating and cooling system prevents this cycling and provides more efficient and lower energy bills.
3. You smell gas
There’s really no guesswork here: if you smell gas – it’s a sulfurous rotten egg odor – clear out.
Get your family out of the home before you try to fix the problem. Follow these steps:
- Don’t touch any lights or any appliances or electronics. The smallest spark can light the gas.
- If you have windows open, leave them open. If you can, open some windows on the way out, but quickly, and then get out of the house.
- Leave your car if it’s parked in the garage. Turning on the ignition or using a garage door opener can both cause a gas explosion.
- Call for help from a neighbor’s house. Don’t use your cellphone or landline while in your home if you suspect a gas leak.
- If the utility company can’t get there right away, have a plan to keep your family somewhere else until the problem is fixed.
And remember: Don’t turn off your gas on your own unless it is safe to do so.
4. The pilot light isn’t blue
The flame in your pilot light should be blue. If it seems more yellowy, you may have a combustion problem, which can mean carbon monoxide build-up.
Carbon monoxide is a problem. Its lack of smell, color or taste makes it tough to detect, but exposure to it can be harmful or even fatal.
If the flame in your furnace is anything but blue, it’s time to consult with an HVAC expert. But you may also see burner malfunction caused by condensation and soot. Regular cleaning of the burner assembly – once per year – can prevent this issue.
