It’s nearly Halloween and it seems fitting because your furnace makes noises that would scare the bravest of children out trick-or-treating. With the racket your furnace is making, you can expect your house to be pummeled with eggs and strung with toilet paper on Halloween.

Now, nobody likes climbing into their crawlspace or descending into a dark basement to see just why their furnace is making funny noises, but you should because a noisy furnace could be a dangerous furnace. Total care Heating and Air, your furnace repair service in Riverside, is here to tell you a little about the scary sounds that are coming from your furnace.

Whistling

A whistling sound could indicate a dirty or clogged air filter. Restricted air going through your furnace could cause a whistling sound. This is an easy fix as all you need to do is replace the air filter and the problem is solved.

Buzzing

If you hear a buzzing noise coming from your furnace it is almost always the result of a loose part. Over time, screws holding furnace components in place become loose and create a buzzing sound. If this is the case, you need to give us a call right away and we can resolve the issue.

Clicking

It is quite normal to hear a clicking noise when you turn on your furnace and when it turns back off again. But if you hear a clicking noise when the furnace attempts to start up and then it shuts down without turning on, you could have a problem. You might have a problem with your flame sensor. It is time to call in a professional and check things out.

Squealing

Screeching, squealing and grinding noises are usually associated with your blower. Either the blower has slipped off its track or it has been loosened. It could also be motor bearings that are failing. Whatever the cause, it will take the help of an HVAC professional to get things right again.

Scraping

If you are hearing the lovely tune of metal on metal m/, it could be your blower wheel. Your blower wheels could be loose and scraping the side of the housing. A piece of your furnace could have come loose and is now stuck in your blower wheel. Your blower wheel could be simply broken and needs to be replaced. As soon as you hear this noise, turn off your furnace and give us a call right away. Ignoring this problem could lead to further damage and expensive repairs.

Rattle

If you hear a loud bang or rattle as your furnace kicks on, it could be a cracked heat exchanger. Cracked heat exchangers are a big cause of carbon monoxide leaks and this problem could turn deadly if ignored.

If you are hearing rattling while your furnace is on, it could be loose connections in your duct system. Either way, call your HVAC technician and have your furnace looked at right away.
