In the past, gas and oil furnaces relied primarily on gravity to move combustion byproducts away from your home. These gases are extremely harmful, so it's important to keep them safely away from living spaces. With old, standard-efficiency furnaces, so much heat energy remained in the exhaust stream that the gases could naturally rise through a flue pipe and exit the home.
However, modern furnaces extract more heat from the combustion process.
Any system that moves air through your home will inevitably collect dust, hair, allergens, and other small particles along the way. If you've ever replaced the filter in a small room-sized air purifier or cleaned the top of a ceiling fan, you know how quickly these problems can develop. Your home's HVAC system uses a filter to help protect its components from dust, but it's not a foolproof solution.
Contaminants can still make their way past the filter, allowing dust and other particles to pass over your evaporator or heat exchanger and, eventually, travel into your home's HVAC system.
A gas boiler generates heat and distributes it via a system of pipes throughout your home. Despite your unit's long service life, it won't last forever. After years of use, the system will gradually wear down and lose its effectiveness in heating water. An old boiler can cause great inconvenience in your home as it will take longer to provide heat. If your heating unit no longer serves you effectively, call a heating system installation professional.
The furnace is crucial in warming your home during the cold season. To ensure your furnace works efficiently, you should know how to tell when to repair or replace it. Here are some ways to determine the appropriate remedy for a faulty furnace.
The Cost of Repairs
The average furnace costs between $2,000 and $6,200 based on the type and efficiency level. Replacement prices vary depending on brand, warranties, and location.
When shopping for a new furnace, it is a good idea to do your research. The more you learn about the qualities and features of the various furnace models, the better able you'll be to pick the right one for your home. One concept that is especially important to understand is AFUE. Keep reading to learn what this abbreviation stands for and what AFUE really means in terms of furnace performance.
