Should You Risk DIY Furnace Installation in Whitemarsh Island, GA?

Georgia is known for its warm-to-hot weather, which grows those famous peaches. Even the cool season that lasts from the end of November to the beginning of March rarely sees daily temperature highs drop below a balmy 66 degrees. However, according to WeatherSpark, January is the coldest month with uncomfortable 44-degree lows, so should you consider a DIY furnace installation?

There’s no question as to whether you should have a heating system, even in a southern home. Still, who should get it done is up for debate. At Georgia Air Cooling & Heating, our NATE-certified technicians understand that DIY work can seem tempting, but we’ll explain why you should choose professional HVAC services in Whitemarsh Island, GA. 

Is a DIY Furnace Installation Worth the Risk?

In short, a furnace installation is not worth the risk. An improper process or unit choice can put your system, home, or health in jeopardy. Some of those cases include the following. 

Incorrectly Sized Units Jeopardize Whitemarsh Island Comfort and Unit Longevity

Many homeowners walk into their local hardware store, point to a furnace with lots of benefits, and think they’re walking out with their ideal match. While some base their decision solely on a brand name, others want a small unit to fit in a basement corner or a large one with a lot of power. Still, exact furnace size matters and should correlate with your home’s size and features.

Furnaces work with a British Thermal Units rating, which determines how much energy it takes to raise your indoor temperature by one degree. The higher the BTU rating, the more energy it uses and the quicker it heats your Whitemarsh Island home. Every square foot requires 30 BTUs, so a home calculation based on the following can help you find the right rating during a DIY furnace installation:

• The square footage of the space you want to heat
• Ceiling height 
• The number of door and window openings
• Household insulation 

While an oversized furnace heats your home quickly, it’ll produce hot and cold spots by turning on and off too frequently, causing non-uniform temperatures. On the other hand, an undersized one long cycles, leading to higher energy bills and premature unit deterioration. So, hire a Whitemarsh Island expert to correctly measure your home and unit for indoor comfort and unit longevity. 

DIY Work May Go Against Legal Requirements and Warranties 

Once you get your unit home, it may not be a matter of whether you have the ability but the right to conduct an installation yourself. Many states bar DIY projects of this sort, and Georgia is no different. State law claims only those licensed by the Georgia Construction Industry Licensing Board can perform an HVAC installation. 

So, if you’re not a licensed contractor, you could be in violation of state law and would have to pay a fine for a DIY furnace installation. Furthermore, certain states (again, like Georgia) also demand permits for work on any mechanical systems, including heating and cooling units. Since these units require professional installation, only an expert technician can check with your local building department and obtain these permits. 

If you begin work without the necessary permits, you could receive further penalties. You’ll also have to revert your Whitemarsh Island space to its original condition. 

However, it’s not just the state government you have to answer to since DIY work can also void system warranties. Mishandling or incorrectly installing your unit can cause malfunctions that are your fault, effectively breaking your warranty contract. Therefore, you won’t receive coverage without a permit and will have to pay out of pocket for repairs just as you would fines. 

Determining the Appropriate Tools and Equipment Negatively Affects Time and Budget

Aside from obtaining the right permits, you must also find the appropriate equipment for your DIY furnace installation. Unfortunately, while you may have some of these tools around the house, including screwdrivers and pliers, there are different varieties of each tool, and you may not have the right one. Then, there are other types of tools that don’t come in the average household toolbox whatsoever. 

For instance, you’ll need specialized pipe cutters for your Whitemarsh Island piping system, sheet metal shears for cutting ductwork, and a combustion analyzer for analyzing flue gases. If you don’t have the right tools for the job, you’ll have to spend time and energy researching your material checklist. Then, you’ll likely spend a significant amount of money on equipment you may never use again. 

There’s also the chance of you having to undergo trial and error until you find the right tools, further taking a toll on your budget. So, hiring a professional pays off in the long run. Since many of them have a solid partnership with reputable suppliers, they’ll know exactly what tools they’ll need for any job, saving you time, money, and unnecessary stress. 

Not Understanding the Process Like a Whitemarsh Island Expert Leads To Faulty System Functioning

However, it’s not just the tools you may be unfamiliar with but the process of a DIY furnace installation as well. For instance, it may be obvious that you should remove any preexisting Whitemarsh Island heating system before installing a new one in its place, but knowing exactly how to do that can be a challenge. After shutting off the breaker panel, you would have to:

• Carefully disconnect the ductwork
• Remove the electrical and gas lines from the unit
• Undo the mounting screws under the access panels
• Pull out and correctly dispose of the furnace. 

From there, the installation process begins. That includes everything from checking that your ductwork is properly sized and your gas and electric lines are set up to finally conducting test runs. Without a thorough installation checklist, many of these steps fall through the cracks, like sealing the gas line or opening the intake damper to empty the drain line. 

Since an experienced Whitemarsh Island technician has years of experience, you know they’ve completed this process countless times. They also have a formal checklist, ensuring they don’t leave anything out. 

Improper Gas Connections Can Harm Yourself, Your Family, and Your Home

Among the steps of DIY furnace installation is connecting the gas supply line to your gas-burning furnace. However, improperly sealing the connection can cause a gas leak. The same can be said about:

• Using a small pipe size that restricts gas flow and builds up pressure
• Improper ventilation that causes carbon monoxide to build up
• Poor support for the gas line
• Not using approved gas line materials 

When gas odors invade your Whitemarsh Island home, one of the first things you may notice is a change in your and your family’s health. Headaches, dizziness, and nausea can occur almost immediately, but respiratory illnesses, brain damage, and even death can occur with long-term exposure. Unfortunately, this is far from the only concern.

Something as small as an electrical spark or lighting a match near the leak could start a fire. Worse yet, if the gas leak has time to build up significantly before ignition in an enclosed space, an explosion can take place instead. So, to avoid DIY furnace installation safety hazards like these, allow a technician with a permit to handle the natural gas line to take the reins. 

Mishandling Electrical Connections Causes Electrocutions and Fires

While only a gas furnace is capable of the gas leak dangers mentioned above, all Whitemarsh Island furnaces require electricity to function. That’s because the ignition system, blower motor, and many other parts need a current to perform. However, mishandling your wiring system causes dire effects similar to a gas leak.

For one, there are three main types of wires. The hot or live wires are red or black and carry the electrical current to the furnace, while white neutral wires bring electricity back to the power source to complete the circuit. The ground wires are copper or covered in a green coat and send excess electricity into the earth to keep from overloading your appliance and causing electrocutions or fires.

Mixing up this electrical wiring leads to severe electrical shocks. However, even if you can get these straight, other things you should look out for are:

• Damaged wires that look frayed or worn since they can spark and cause fires
• Overloaded circuits that cause overheating and potential fires
• Loose connections that generate heat and ignite nearby flammable objects
