Hello, my name is Jacob. I would like to talk about proper installation and repair of the HVAC system in your commercial building. Full scale HVAC systems for commercial buildings require ongoing maintenance and repairs to keep every floor and room at a comfortable temperature. These temperature control systems also control the air quality in the building by sending the airflow through filter elements. My site will cover all aspects of the upkeep needed for these systems. I will also talk about the benefits of keeping your air quality and temperatures at desirable levels. Thanks for coming to visit my website.
Furnace companies are continually looking to improve their models and their overall technology. As such, each time you shop for a new furnace, you may feel like you're navigating a whole new vernacular. Lately, the term "two-stage furnace" has been showing up a lot. If you're like most people, this has you asking what a two-stage furnace is, and whether or not you need one. You'll find those two questions answered below.
What is a Two-Stage Furnace?
A typical, one-stage furnace has one mode or stage: on. If it is not on, it is off. A two-stage furnace is one that has two modes or stages: low and high. Such a furnace will usually operate on low. In this mode, it produces less heat and often blows the hot air out at a limited speed. When the demand for heat is higher, it can kick into "high." When on high, it will generate more heat, and it will generally also blow the heated air out faster.
You do not have to turn a two-stage furnace from one mode to the next. The change happens automatically in response to the temperature differential in your home.
Do You Need a Two-Stage Furnace?
Two-stage furnaces do have some key advantages over ordinary, one-stage furnaces. For one, they tend to be more energy efficient. Most of the time, your furnace will be running at that lower setting, which conserves energy. Two-stage furnaces also tend to heat a home more evenly. When the air being blown out is not quite as hot, it disperses better and you get fewer hot patches throughout the home.
The downside to two-stage furnaces is that they do cost more than one-stage models. So, while they will save you money over time, there is a higher up-front cost in order to access those eventual savings.
The consensus tends to be that two-stage furnaces are a good buy in mild to moderate climates. In areas with harsher winters, a two-stage furnace won't yield such remarkable energy savings. This is because, in really cold climates, the two-stage furnace will run on "high" pretty often, which burns through more energy.
If you live in a mild to moderate climate and have the money to spend up-front, replacing your furnace with a two-stage model can be a smart choice. Talk to an HVAC contractor to learn more about the specific makes and models that may work best in your home.
