A high efficiency HVAC system is something you may be aware of for your home. The furnaces that are produced now, are more efficient than the older systems from just a decade or two ago. This is because the furnaces that are produced now are built more efficiently. This is because of the technology and features that are now being used in the heating industry. It has allowed high efficiency furnaces to do two things. They extract more heat out of the gas they consume. Also they only use the amount of energy that’s necessary to get the job done at any given time.
A Newer furnace
Newer furnaces use an electronic ignition instead of the gas powered pilot light. Those that were used in older furnaces. This ignition is only used when the furnace needs to turn on. It makes it more energy-efficient than keeping a small flame burning at all times.
Many high efficiency gas furnaces come with two stage heating. The lower stage of heating is able to use less energy and works a majority of the time, while the higher stage only kicks on when it’s very cold out and more heat is required.
How they work
Similar to two-stage heating, a variable blower operates at different capacities. This depends on how much it’s needed at any given time. When more airflow is needed a faster speed is used. Usually this happens when the filter is clogged. When the blower of the system has a alert that notices less airflow is needed, it will switch to a lower speed in order to conserve energy.
For the combustion system to work properly, the furnace will need to draw in a certain amount of air. Unlike furnaces with unsealed combustion, which utilize the heated air from around your home can be different. Sealed combustion furnaces draw in air from outside in order to conserve energy and improve safety levels. If you notice an issue with your furnace, call us. No matter the age of the furnace, it will need to be looked at.
