How often should I oil my furnace blower motor?

Furnace Maintenance If the motor has oil ports, it should be lubricated annually. Apply two or three drops of 10-weight nondetergent motor oil (not all-purpose oil) to each port. Do not overlubricate. If the blower shaft has oil ports, it, too, should be lubricated annually, following the same procedure.

How often should furnace blower be cleaned?

A professional should clean the blower assembly on your furnace at least yearly. If the furnace has a squirrel-cage fan, cleaning the blower assembly is all the more important. That's because the openings in this type of furnace tend to become clogged with dust and dirt.

Should you clean your furnace blower?

Three parts of the air-moving system should be kept clean: the filter, the blower, and the blower motor. Dirt is the biggest enemy of your furnace. It can waste fuel and drastically lower efficiency. Dirt affects all three basic components of your furnace, so cleaning is the most important part of regular maintenance.

Why is my blower motor so loud?

The blower motor needs routine lubrication, and often a specific kind of lubrication to upkeep performance and function over time. Otherwise, the fan might seize up and cause a loud noise (and an even louder repair bill). If you are knowledgeable of the process, you can add lubrication to the motor.

Why is my furnace so loud all of a sudden?

The simplest explanation for screeching or whistling is that your furnace air filter could be clogged with dust, hair, and dirt. That eerie screech you hear might just be air desperately trying to get through. Fortunately, you can take care of this noise issue yourself, quickly and inexpensively.

Why does my furnace sound like an airplane taking off?

Why is my furnace not blowing hot air?

Troubleshooting Furnaces Not Blowing Hot Air Check batteries of your thermostat and replace the drained or faulty one. Check the fan settings on your thermostat if they are set to “auto” instead of “on”. Make sure someone else has not set your thermostat to a lower temperature.

How much does a furnace blower motor cost?

Furnace Blower Motor Replacement Cost On average nationwide, a furnace blower motor replacement costs $400 to $600, including parts and labor. A single-speed blower motor costs around $450 to replace while a variable-speed motor costs $600 or more.

Can an oil furnace explode?

An oil-burning furnace with a leaky seal may throw improperly atomized oil into the furnace's combustion chamber, which eventually pools at the bottom of the chamber. The pools partially vaporize. They ignite when the furnace cycles on, causing an explosion.

When should I worry about my furnace noise?

In most cases, it is wise to call a service technician. A pinging or popping sound is most likely coming from one of the ducts and is not really something to worry about. If you hear an odd vibrating noise or whining, it may indicate a problem with your furnace and a technician really needs to check it out.

What are normal furnace noises?

Normal Furnace Sounds Chirp – Chirping sounds are fairly common. It's usually the natural noise of the mechanisms. Rattle – Rattling noises usually happen when the system is cooling down and it's not generally cause for alarm. Hum – This is usually a sound that happens when the furnace burner lights.

Why does my gas furnace sound like a jet engine?

Blocked or closed vents can cause increased sound pressure as the furnace blower motor and fan push air through, resulting in a “jet engine” sound.

Can I clean my air ducts myself?

When it comes to the nitty gritty, cleaning air ducts is not a do-it-yourself job. It requires tools, such as a high-powered vacuum and rotary brushes, that you don't have lying around in the garage. In addition, an improper cleaning job could damage the ducts, resulting in expensive repairs.

Can you use a shop vac to clean a furnace?

A regular vacuum or a shop vac and a sink or garden hose are some of the most important tools for cleaning a permanent furnace filter. Beyond that, simple household items like toothbrushes, scrub brushes, toothpicks and cotton swabs are also useful to clean the furnace and its vents.

What maintenance does a furnace need?

Some of the specific tasks involved in our furnace maintenance checklist include: Inspecting the vent system and air intake grilles, removing any blockages. Checking the heat exchanger for signs of damage or corrosion. Examining and cleaning the blower, removing any debris.

How often should an oil furnace be serviced?

You should have your oil furnace serviced at least once a year. If the furnace is used more than average, you'll want to schedule routine service every six months. A furnace may be used more often in freezing climates or areas with long winters.
