Furnace Repair Service: Gas Furnace Maintenance Tips

HVAC contractorDo you have a gas furnace in your home? While gas furnaces are highly energy efficient, their main flaw is that if you don’t properly maintain them, they tend to produce carbon monoxide that is often harmful to you and your family members.

For you to protect your property and loved ones, you need to keep your furnace in top condition. To help you out, here tips that you should follow as given by furnace repair service providers:

Ensure you are working under safe conditions

Gas appliances can strike anytime; therefore, you should be cautious when interacting with them. For you to have peace of mind when handing the appliance, you should ensure that the appliance is switched off.

Ensure that the power system and circuits connecting the furnace are off. You also should check the gas leaks before you do anything. You should note that if there are any leaks, they are extremely dangerous and can cause fatal accidents.

Are there leaks in your unit? Ask a professional to look into them and fix them before you do anything. It’s only after the unit has been fixed that you should proceed.

Clean or replace the air filter

The air filter is a major part of the gas furnace as it prevents dirt from getting into the furnace. When the air filter gets dirty, it prevents the furnace from working as effectively as it’s supposed to. The furnace also tends to work harder thus consuming a lot of fuel.

For you to keep the furnace in top condition, you need to open it up and access the filters. Are they dirty? You should clean them. It’s common to come across filters that are too damaged. In such a case you should simply replace them. When buying the new filters, go for high-quality units that will give you a great service for a long time.

Take a look at the fan belt

Just like in a car, fan belts wear out and get loose. As you can guess, when the fan belt isn’t functioning properly, the furnace won’t function optimally. Take a look at the fan belt driving the blower. What is its condition? Is it glazing, fraying or cracking? If you see any of these signs, it’s time to replace it.

While you are at it, you should also take a look at the belt tension. For you to do it you only need to push the belt down at the center and feel whether it’s taut or deflated.

If loose, you need to tighten it by loosening the attachment bracket. You should then move the motor assembly so that the belt tightens and at the same time holds the motor assembly in place. Once you are done, tighten the attachment bracket.

Lubricate the moving parts

These are basically the bearings. If you have an older furnace or the motors aren’t permanently sealed, you need to oil the bearings. In most cases, you will have to remove the blower motor to gain access to both ends of the motor.

To oil the unit, you need to find the oiling caps that are located on each side of the motor. It’s also common to find one on the bearing shaft. You should remove the caps and drop a few drops of the lightweight oil then replace the caps. When oiling the bearings, take care that you don’t over oil.

Check the thermostat

The thermostat determines how well the furnace works. To ensure that your furnace is working optimally, confirm that the thermostat is properly set. You also should check its condition. Is it too damaged or worn out? You may need to replace it.

Take a look at the vents

Gas furnaces are usually hooked with venting systems. The vents get blocked due to large amounts of dust and debris. Just like dirty air filters, dirty vents make the furnace work too hard than it should. For your unit to function optimally, HVAC companies Long Island recommend that you clean the vents.

All you need to do is to remove the vent cover and clean the insides of the vents using a vacuum cleaner. When it comes to the outside of the vents, use a large brush.
