There are different models and makes of furnaces in the market nowadays and as a result selecting the right one can be daunting task. The gas furnace is one of the most popular types. It is highly regarded for its cost effectiveness and there are a number of its models in the market boasting of one feature to another. But you should not just go with the hype on the market. You should take time to research and establish which type of furnace is going to operate with maximum efficiency in your home.
The gas furnaces are fired up using natural gas which is one of the cheapest fuels in the market. This is in fact one of the reasons why many people like the gas furnaces. If you take good care of them, they are going to last for approximately 20 years, and as a result you are going to save more on operating the gas furnace as compared to using an electric furnace. A certain level of maintenance is required for all furnaces if you want them to last for the longest time. There are some that will require monthly clean up for the filters to work properly.
For your gas furnace to work efficiently, regular care will need to be done on it even though it will not be a lot of attention like in the case of an oil furnace. Unlike gas furnaces that do not produce soot, oil furnaces usually produce soot that blocks the filters as well as other passages. It is for this reason that they require intensive maintenance compared to gas furnaces. Aside from cleaning the filters of the gas furnace, you will also need to make sure that its motor is cleaned and oiled.
From time to time, you will need to hire a qualified technician the check the furnace’s circuit boards, pipe leaks, ventilation system and other parts. If you do not maintain your furnace properly, it might start experiencing problems that you had not planned for and as a result its lifespan will be shortened. When buying a gas furnace, another thing you should not forget is its efficiency rating. A good furnace should be compliant to the Annual Fuel Utilization Efficiency rating that has been set by DOE which should not be below 78 percent.
A furnace that has a higher efficiency rating is more efficient. You will also need to ask for a furnace that has a variable speed fan. Some of the furnaces usually have poor quality or design of the furnace. Such a furnace may end up wasting your electricity needlessly, and in the long run your money. It may also cause uneven heating in your house and its ducts could be noisy. A gas furnace that has a variable speed fan will help you avoid these problems. It is therefore important to ask the contractor you are buying from to verify that the fan is compatible with your ductwork.
