But, as a service company offering heating and air condition service in Madison, AL, we know from our experience of successfully conducting HVAC installations and resolving concerned issues, that this is not a complete list. Air flow profile of a furnace is also an important factor that many homeowners pay little attention to, when making a decision for a new purchase.
How can a specification as trivial as air flow pattern—whether the air goes up or down—impact the quality of bought solution? Why is it important?
Our customers ask.
Allow us to explain the importance of assessing air flow profile of a furnace before making a purchase decision.
Why Air Flow Profile of a Furnace Matters?
It matters because,
- The air flow profile of a furnace eventually helps to decide the ideal installation location of the unit. Yes, some HVAC contractors have to circumvent their way around the established standards, but that comes at a cost of: either reduced efficiency; increased labor time, or increased installation cost.
- The efficiency of the purchased unit is also affected by the air flow profile of a furnace. Ask any service provider which deals in heating and ac in Madison, AL and they will tell you that the more natural the air flow pattern of a furnace, the higher is its efficiency.
- The air flow profile of a furnace also plays an important role in the actual shelf life of the bought solution. This is an extension to the previous point of efficiency. If a furnace has an unnatural air flow pattern, the components will expend more energy to deliver optimum heating, which directly impacts the long term durability of the bought furnace.
What Are the Options Available in the Market?
There are different types of air flow profiled furnaces available in the market.
You can purchase a horizontal air flow furnace, a downflow furnace, an upflow furnace, an upflow-horizontal furnace or a downflow-horizontal furnace.
However, in this blog, we will limit our discussion to the downflow furnaces and upflow furnaces, to provide a more comprehensive and focused outlook to our readers. Furthermore, these two are the most widely installed furnace solutions in the residential homes and commercial properties. Working with trained professionals who provide reliable heating and air condition service in Madison, AL will help to ensure that you install a heating system that fits your home and your needs.
What is an Upflow Furnace?
An upflow furnace is a type of furnace that draws in cold air from the bottom of the unit. The heat exchanger then warms the cold air, and finally expels it from the top of the unit. It then runs around the ductwork, supplying warm air to the indoors and providing a comfortable living environment for the occupants.
Where can you install it?
Upflow furnaces are designed for properties that have a basement, a garage or a crawlspace inside the premises. This is because, since the air flows from bottom to top—a natural flow pattern for warm air—by placing an upflow furnace at a lower elevation to the vent terminals helps the HVAC system to work with maximum efficiency. Make sure that the HVAC contractor positions the unit on concrete foundations during the installation of the furnace, so that it creates a room for efficient air exchange.
Are there any important installation considerations for an upflow furnace?
Make sure that the contracted company, providing heating and air condition service in Madison, AL:
- Possesses in depth and up-to-date knowledge of local building codes before starting the installation project.
- Installs the upflow furnace at an adequate distance from the wall.
- Positions the upflow furnace atleast 4 feet clear from any electric or gas meter, regulator and outlet.
What is a Downflow Furnace?
A downflow furnace draws in cold air from the top of the unit, the air is warmed in the heat exchanger, and the warm air is then expelled from the bottom of the furnace. It works against the natural flow of warm air and hence, requires more energy to provide same levels of comfort as an upflow furnace.
Where can you install it?
Unlike, upflow furnaces, a downflow furnace can be installed in any type of property—irrespective of the fact that whether there is a crawlspace or a basement to accommodate the unit. Usually, downflow furnaces are installed in wide open attics as the downward flow of the air can be efficiently carried by the ducts running through the attic. For a tailored deployment approach, please consult a local company that provides reliable heating and air condition service in Madison, AL.
Are there any installation precautions to take care of?
When installing a downflow furnace, besides the usually exercised precautions, it is important to note that the unit should be placed over a reinforced subflooring, avoiding combustible materials like carpet or tile at all cost. This is understandable from the fact the unit expels warm air from an outlet that is positioned at the bottom. We would like to reiterate that please ensure the installation is carried out by a reliable local service provider that deals with heating and ac in Madison, AL, to avoid any harmful accidents.
If downflow furnaces provide convenience of installation and have been ideally designed for attic based deployment, then why do some HVAC contractors install upflow furnaces in the attic?
We all know placing an upflow furnace in the attic is not a good idea, as it reduces the efficiency of the HVAC system, yet these installations are common. In some cases, this is a mere lack of understanding exhibited from the contractors’ side. But, in majority of cases, there are certain restrictions which force them to opt for the solution.
- Installing a downflow furnace can be financially infeasible due to the extra cost that comes with reinforced subflooring.
- The homeowner prefers the durability of an upflow furnace over the downflow furnace, but does not have a crawlspace or basement to install the unit.
- The client has already bought an upflow furnace, and now, the HVAC professional does not have any other option than going forward with the installation.
It is therefore important that you consult a local company that deals in heating and ac in Madison, AL before investing in a furnace unit.
An Upflow Furnace or a Downflow Furnace?
Where a downflow furnace offers more flexibility in terms of selecting an installation location over an upflow furnace, the latter offers more efficiency, extended shelf life and increased comfort. In the end, the decision could be an eventual tradeoff, something that your HVAC contractor will help you guide through by assessing your individual case.
