5 Tips on What to Do Before Installing Furnace
An article outlining what a furnace is, why it is a useful addition to one’s home, and tips on how to properly install one.
What is a furnace?
To begin, it is important to first understand what a furnace is, and the functions it provides to gain more insight into why a furnace may be a fantastic addition to your home. Firstly, a furnace is a crucial part of an HVAC system that contributes to the heating throughout a building by circulating warm air throughout the space with the help of ducts and vents that disperse it. More precisely, the air is collected by a return register filtering out particles such as dust.
A thermostat will then be responsible for starting up the furnace through the ignition of a burner located in the furnace’s combustion chamber. The subsequent flames produced will warm up a metal heat exchanger which travels through tubes that warm the air. Finally, a blower motor and fan are tasked with the dispersal of heat throughout the building via vents that are placed throughout the home.
It should also be noted that there are several types of furnaces to choose from, ranging from natural gas, electric, propane, and oil that all have different pros and cons in terms of cost, efficiency, and ease of installation. That said, for the purposes of this article, we will be focusing on the installation of natural gas furnaces as they are the most common furnaces. Additionally, whichever furnace you chose, it is best to consult a certified HVAC technician to ensure a safe and reliable furnace repair and installation.
Tip 1: Consider issues of space, cost, and B.T.U
Now that you know what a furnace is, the first step in installing one is to determine where it will go, what your available budget will be, as well as its ability to heat your home effectively and efficiently. It is important to factor in the space you have available for the furnace, as it will need to be able to fit adequately within the area. In addition, deciding upon a budget for the furnace itself along with any installation costs should be factored in beforehand to ensure you do not exceed your budget requirements.
While space and cost may be considered more straightforward issues, the efficiency of the furnace may sometimes be a bit more confusing. A furnace’s efficiency is measured in B.T.U’s or British Thermal Units, which will impact the system’s ability to heat the entirety of the home depending on the square footage it will be required to heat.
If this condition is met, the furnace will be adequately able to heat every part of the building. An easy way to understand this is in terms of an efficiency rating. For example, a furnace with an efficiency rating of 80% within your home means that 20% of the heat will not be used to heat the home. As such, the higher the efficiency rating, the greater the furnace’s ability create and disperse heat throughout the home with minimal heat wastage.
Tip 2: Turn off Gas, Electricity, and Drainage Links
In terms of the actual installation of the unit, a simple but remarkably important tip is to shut of the gas supply along with the electricity and drainage links. This is because when installing a furnace, it is extremely dangerous to proceed with the installation without doing so due to the risk of issues such as fires, electrocution, and flooding it could present.
Therefore, before doing anything else, ensure that this step is completed given the negative safety and house damage risks associated with neglecting to do so.
Tip 3: Consider Location and Connections
Once you have decided where your furnace is to be placed, make sure you are aware of where the return duct is that the furnace will be connected to. Depending on the location, you may have to connect them together using additional piping if they are unable to reach each other from the desired location.
Moreover, ensure that the required piping such as the PVC exhaust and inlets are secured well to avoid potential leakages. Be sure to check for any gas leaks before moving on any further and consider utilizing a carbon monoxide monitor to alert you of any potential leakages in the future.
Tip 4: Ensure Adequate Drainage Flow
While the aforementioned tip will help to avoid leakages, when it comes to water leaks, in particular, it is also advisable that the system is installed on a slight downward tilt facing the direction of the drain. This will ensure that any inevitable condensation expelled out of the system will be directed towards the drain to avoid excess water pooling. This is because if the system is flush with the ground, the water will have a more difficult time flowing into the drain, but rather begin to collect on the surface of the floor, which of course is not ideal.
Tip 5: Follow Electrical Wiring Instructions Carefully
Finally, to allow the furnace to become operational, the electrical wiring must be properly done. The instructions regarding how to do so will generally be included with the purchase of the furnace itself, such as how to install both regular and low voltages. Thus, as with all instructions it is best to follow the instructions carefully and be sure to turn the electricity off beforehand as a method of staying safe from the danger of electrocution once again.
In sum, while installing a furnace may seem like an impossibly daunting task, if you follow these five simple tips you will be on your way to installing your furnace with ease. However, please keep in mind that the best and safest option given the very real health and safety risks associated with furnace installation will always be to hire a certified HVAC technician to do the job for you both safely and effectively given their unbeatable knowledge and expertise in the field.
