The primary essential part of home maintenance is furnace cleaning. Every home needs a regular furnace cleaning to make your furnace smooth working. A clean furnace improves your air quality. Furnace and air ducts are interlinked, so when a furnace is full of dust, dirt, debris, and other contaminants, it will complicate the functioning of the duct. A clean furnace has an overall impact on the HVAC system.

It refers to the annual professional inspection of the furnace. Yearly maintenance by professionals helps your system to maintain itself longer. A furnace cleaning process also includes spotting and correcting malfunctions before they cause any dangerous impact.

How does a furnace work?

The furnace is something you never really think about until it stops working, but it’s much easier to troubleshoot problems with a little bit of knowledge. You need to know how a furnace works. First, we will tell you the basics, then we will learn about the other things. So you can easily understand what each component does and how they work. There are many differences, all gas furnaces work in the same primary way. Natural gas burned to warm up the heat exchanger, and exhaust fumes were released through the gas vent. The boiler fan pushes air over the heat exchanger and circulates it around your home. The furnace runs until the thermostat detects the right temperature and shuts the furnace off.

Modern furnaces used a draft inducer fan to help exhaust the emissions. This force draft also increases the efficiency. Condenser furnaces used a dual. Heat exchanger to condense water vapor extracts even more heat out of the combustion. Furnaces are always related to AFUE (Annual Fuel Utilization Efficiency). This number is a ratio of fuel burned versus the fuel converted into heat. Older furnaces will have an efficiency rating of 70 AFEU or less, which means that only 70% of the fuel is turned into useable heat. Mid-efficiency furnaces are around 80 AFUE, and high-efficiency condenser furnaces are generally 90 and above. Furnaces can be single state or dual state, which means their other full heat or no heat. Two stages furnace can run at full speed or produce speed when less heat is needed. It allows for the furnace to run quieter and may contain a more consistent temperature.

Furnace Maintenance Guide 

A dirty furnace that circulates dust around your home is less efficient and more expensive to run. Your furnace should be cleaned and inspected before its first turned on. It gives a chance to identify any problem beforehand. So you won’t have any surprises when winter arrives.

What will you need?  

First, you will need gloves, a vacuum, a Brush, a furnace filter, and a screwdriver. When working on your furnace, always shut off the power and close the gas value. Replace the filter. A furnace filter removes dust, pollen, and other particles from the air. Over time a build-up of dust on the filter will restrict the airflow. To reduce the efficiency of furnaces, if the airflow decreases too much, it can be overheated the heat exchanger. It is why it’s essential to replace the furnace filter every three to six months. The cold air is located filter on return duct. Pull the filter out and look at the direction of the arrows on the filter. In most furnaces, the disposable filter will have a cardboard frame. In some models, it can be vacuumed or washed. But first, check your furnace manual. If you don’t see any number on your filter, stand the filter upright and measure the height, width, and thickness. After you selected the filter types and size then select the minimum efficiency reporting value. MERVE rating will tell you good a filter is at cleaning the air.
