There are pretty much three kinds of furnaces out there on the general market. However, two of them are without a doubt the most popular and commonly used ones: the ones with a single-stage speed and the variable speed unit. The HVAC system which operates efficiently in your home would generally be based on a few different factors which include heating, insulation, sizing and other requirements which would matter.

The Consultation

Before you go ahead and invest a serious amount of money in the new heating system, it would undeniably be best to consult a professional HVAC Contractor. He would make the necessary suggestions and recommendations as he would have the knowledge, experience and expertise for assessing the home in order to determine as well as to establish the right options for your heating system.

Single Stage Furnaces

These are called single speed furnaces as well. It is pretty much because they only have one stage when it comes to high heat output. This would continually disperse the maximum heat capacity that the furnace is capable of, regardless of the temperatures inside or outside. In other words, it is capable of switching from one speed to another without having any type of variation. This is why it’s not as cost efficient. This is also something which would increase the overall amount of your electricity bill so keep it in mind. Thus, you might want to consider your budget and the future bills before investing in it.

Variable Speed Furnaces

Unlike the previous counterpart, this is a unit which is going to operate on a range of different speeds and it’s going to have the ability to control the heat flow of the cooler air inside the entire house precisely. You would have the ultimate control over your air flow and this means that your humidity as well as your temperature is actually well-balanced. As you use advanced technology, the variable speed furnace is going to do a constant monitoring of the information which comes from the actual HVAC system. This would allow it to conveniently adjust the comfort level of the actual temperature automatically.
Thus, ultimately, when you stack these up with single-stage furnaces, the variable speed furnace does not operate on a number of different stages. Instead, it would refer to the fan motor of the furnace. This particular component would operate at different speeds which would enable you to properly control the heated air which has been dispersed. This is something worth considering.
As you can see for yourself, there are quite a lot of things that you would have to account for at the end of the day. This is undoubtedly something important and you need to make sure that everything is handled properly. Thus, you need to find a good HVAC professional to consider your requirements and help you make the right choice.
