HOW TO SERVICE YOUR FURNACE ON YOUR OWN.


Your furnace needs to have annual maintenance, this means it may need to be done and we can't find the cash to do so, and not servicing will leave you in the cold eventually. Don't worry though, there are DIY methods to almost everything that needs to be done, and we have got you covered. Unfortunately, this will not be easy, ranking the difficulty level to be hard and taking up to 3.5 hours to be completed. The bright side to everything is that it will all cost you anywhere between $30 and $50.

TOOLS NEEDED

  • Screwdriver
  • Wire brush
  • Shop vacuum
  • Strap wrench

MATERIALS NEEDED

  • Foil tape
  • Air filter ( for the furnace)
  • The oil filter ( for oil systems only)
  • Oil nozzle ( for oil systems only)

Before starting, ensure all power to the unit is off. Trip the breaker or remove the fuse. If you can identify the main breakers, throw it. P.S After doing this, if you have a gas braker and smell gas, leave the house immediately. Do not change any light switch ( leave ones that are on, on, and ones that are off, off). Go to the sidewalk and call the gas company or fire department.

BLOWER AND MOTOR

You will need the following pieces of equipment to clean your blower :
  • Screwdriver
  • A replacement filter
  • Toothbrush
  • Vacuum cleaner
  • Clean bags

Inspect your filter first, depending on the condition of it, you will need to replace or clean it. The professionals recommend doing this up to a month before the winter season and then once per month while using the system. Filters normally cost anywhere from $2 to $15, all depending on the quality. Cleaning the blower's assembly comes next. This includes belts, pulleys, and housing. You can find your blower behind the filter.

Remove the blower to clean the fans first. It's normally held by screws, so that's where you're screwdriver will come in. You will use the toothbrush to clean the blades and small spaces between the blades. After that, we rely on the vacuum suction to clean out the debris you cleared out.
If you are dealing with oil ports, put 2-3 drops of 10- weight, non-detergent motor oil, to each port. The oil will cost between $2 to $3 per quart and can be bought at any local haberdashery.


INSPECT THE BELT


The belt of the motor should always be firm, giving no more than ½ inch when pressed on. Inspect it as it should be free of cracks and damages. To remove or replace the belt, you will need a wrench. We advise you to loosen the bolts, not remove them, you only need the bolts loose enough to slacken the belt and move the motor. If the belt needs to be removed, a replacement belt will cost $4 to $6 dollars. You can find these at Walmart ca.

Check your vents and chimneys. This will require that you go outside and inspect your vents or chimney. Ensure that no blockage is caused by snow, debris, nests, etc.
Also, check your ducts for leaks. Check for separation at the duct joints. Incase any is found, you will need to seal with metal tapes. After the servicing is completed, turn the system back on and feel for leaks that you might have missed initially, then apply metal tape over it again.


OIL FURNACES


Now if you have an oil furnace, a few extra steps need to be taken.
  • Replace oil filter. (oil will pour out once the filter is dislocated, so remember to lay a bucket or container to catch the spill).
  • Bleed your filter lines, make reference to the instruction from the manufacturer’s guide, which normally comes with a new filter.
  • Inspect for leaks. Tighten if needed.
