The expected lifespan of a gas furnace is 15 to 20 years. Between 15 and 30 years, electric furnaces are expected to last. However, if they are not cleaned and maintained every year, furnaces can break down in as little as 12 years, despite their extended lifespan. Get your gas or electric furnace checked out as soon as possible. You may end up paying a lot more for a winter repair because of the cold weather. Keeping your furnace in good working order will help you save money in the long run.

Combustion chamber disinfection is an essential part of furnace maintenance.

The combustion chamber ensures that the air and natural gas mix safely. However, a cloud of soot, gas, and vapor rises from the chamber’s flames as they begin to burn. Avoid the deterioration of the combustion chamber’s internal walls, and the combustion chamber must be cleaned and maintained at least once a year.

Holes and fissures will appear as the combustion chamber degrades. To avoid a gas leak, have your furnace serviced and inspected by a professional once a year. With a bit of wire brush, you can easily clean the chamber. The brush helps clean out the furnace of dust and other gunk. After that, use a commercial vacuum cleaner to clean the chamber, heat exchanger, blower motor, gas burners, and electric ignitor.

Analyze the Exhaust and Combustion Gas

It would help if you employed combustion inspection equipment to determine the composition of natural gas and exhaust gas in the flue pipes of your furnace. A probe designed to be put into the exhaust pipe of a furnace is used as a combustion inspection tool. In addition, preparing to connect to the flue pipe with the combustion inspection instrument helps calibrate it properly.

Activate the inspection tool outside to check for any exhaust leaks in residence. After that, check to see if the house has a furnace of the correct type. For instance, an airtight connection between the combustion chamber and the exhaust pipe is provided by a condensing furnace. Starting with the flue pipe, begin by drilling a small hole. To get CO measurements, connect the probe of the combustion inspection equipment to the exhaust pipe. A high-efficiency furnace’s CO exhaust concentrates between 100 and 400 parts per million (PPM). Close the exhaust pipe aperture if the CO levels in your furnace are within acceptable safety standards.

Using the Certified Temperature Rise Range, take a temperature rise measurement.

A gas furnace has a sticker with a list of temperature rise ranges confirmed. Two numbers on the badge show the lowest and greatest temperatures. You can determine how much a furnace raises its temperature by comparing the air temperatures coming in and going out of it. First, subtract the return air temperature from the supply air temperature to find the temperature increase rating. For example, if a furnace has a temperature rise range of 40 to 70 degrees Fahrenheit, the incoming air is expected to rise in temperature by a maximum of 70 degrees Fahrenheit.

You’ll feel cold air coming out of your vents if your furnace’s temperature rise is less than 40 degrees Fahrenheit. This is since your furnace only minimally heats the air that enters your home from the cold outside. Therefore, your furnace’s fan should be turned down to compensate for a lower air temperature rise. In addition, you must make sure that your furnace does not overheat the air that enters through the air ducts into your heating system.

The goal of a furnace is to raise the temperature of the entering air by 70 degrees Fahrenheit. Therefore, a temperature difference of more than 80 degrees Fahrenheit will result in short heating cycles if it is present.

Due to fast temperature spikes, overheating means your furnace constantly switches on and off. As a result, both minimum and maximum temperatures climb by about 30 degrees Fahrenheit on average. An expert will check your furnace’s temperature increase range to ensure it isn’t too low or high.

Clean the fan and motor by removing them and soaking them in warm, soapy water.

You’ll notice a buildup of grit and dust in your furnace’s fan and motor during the winter months. To clean the fan, remove the blower component from the furnace. Maintaining the furnace’s blower assembly will improve fan performance and reduce the risk of motor failure.

The furnace might become overheated if dust builds up in the fan and motor to a critical level. The engine’s electrical components will be damaged if the operating temperature is too high. Dust accumulation on the fan blades, on the other hand, makes it difficult for the fan’s motor to spin. Due to overheating, the motor will shut down.

Remove the Control Board from the front panel to disassemble it.

Take care to cut off the furnace’s power before cleaning the fan. Next, remove the furnace’s front panel to get to the blower motor. The two screws holding the door switch in place must be removed after the panel has been removed. Finally, use a flashlight to identify and remove the furnace’s control board.

It is possible to remove the board from the furnace by unscrewing a few screws. After that, remove the furnace’s control board without removing any cables. It is usually possible to clean the blower motor and fan when the control board is on one side of the vehicle.

Cut off the Blower Motor of the Furnace

Two or more screws are used to secure the blower motor and assembly to the furnace. Start by unscrewing the screws that hold the furnace fan in place. Then, with two hands, slowly remove the furnace’s blower motor. When removing the blower assembly, be careful not to damage the wiring. Make sure to clean the motor after removing the fan. After cleaning the furnace, reinstall the fan and replace the screws.

The Heat Exchanger must be disassembled.

Turn off the furnace’s gas and electricity before cleaning the heat exchanger.

After that, use a brush or paper towels to wipe down the heat exchanger’s chambers. The brush may overlook tiny particles challenging to remove with a broom in the chambers.

The heat exchanger chambers should be vacuumed to remove any loose dirt.

Afterward, assemble the furnace and install the front panel.

Before operating the system, make sure the gas and electricity are reactivated.

Replace the air filter on your vehicle.

The ventilation system of your furnace must be able to take in air. Unfortunately, the accumulation of lint and dust reduces the life expectancy of both your furnace and the ductwork. Changing the furnace’s air filter is the most simple maintenance task. Every month, fiberglass filters should be replaced. Premium pleated air filters, on the other hand, have a lifespan of no more than six months. Remembering to replace your filters is the most challenging aspect. Air filters are often installed between the blower and return air ducts.

Clean the Vents and Pipes

Air duct dust is like cholesterol in the arteries in that it accumulates over time. If you have a lot of direction in your ductwork, your furnace’s warm air will not be able to reach every area of your house. Do-it-yourselfers who aren’t licensed HVAC technicians should reseal their ducts to avoid an air leak from occurring.

The following are some extra crucial steps in furnace inspection:

-Find out what the motor’s voltage rating is.

To check for cracks or damage to the belt, inspect the motor.

Find evidence of wear and tear in the wire by inspecting it.

The electrodes and pilot light must be cleaned and adjusted.

-Check for corrosion, holes, and cracks in the heat exchanger.

-Tightening Gas Connections Can Help Prevent Leaks

To Improve Airflow, Install a High-Efficiency Filter.

Ascertain that your programmable thermostat is working correctly.

Inspect the gas pressure to ensure it isn’t out of whack, either high or low.

Keep the motor, bearings, fan, and circulators greased to don’t wear out.
