Some of the worst heating repairs ever performed are done by people who do not know what they are doing. Ductwork that looks like an invasive metallic spider or heat venting through cold air exchange vents is not the way to go. Leaking fuel lines duct-taped to prevent further leaks, and electrical wiring that could set a lot of things on fire are all wrong as well. The following shows heating repair nightmares, and how to avoid them.

Leaking Fuel Lines

Leaking fuel lines prevent adequate fuel from getting to the furnace. Gas and propane are the most dangerous of all leaks because they can fill up a house with dangerous concentrated fumes. A single lit match or lighter and your home becomes a rocket or a bomb. Thinking you can fix leaks by wrapping them tightly with duct tape is not going to work. It only slows the leak, and the pressure from the fuel line will just cause the tape to come loose when you least expect it. The fumes can also suffocate you in your sleep, a double nightmare that you can prevent by ditching the duct tape, closing the fuel line, and calling a licensed HVAC technician. 

Wrong Vents

Can you install new ducts yourself? Sure, you can. Is it possible for someone else to install it and get it all wrong? Yes, but only if he/she is not a licensed HVAC technician. A licensed HVAC technician never installs ductwork the wrong way. He/she always checks to make sure the heat ducts are going to the heat vents in your home, and that the cold air return ducts are connected to the cold air vents. Avoid DIYing this kind of project and you will avoid connecting the wrong ducts to the wrong vents.

Too Much Electrical Wire

Connect blue to blue, red to red, white to white, green to green, and yellow to yellow, right? Sure, electrical wiring for your furnace seems so easy, but it is a lot more complicated than that. Electrical components are connected via color-coded wiring, this is true, but it is not universal across devices and appliances. Additionally, most wiring has to be soldered into place so that the bare end of each wire is in direct connection to a diode or command switch. Lots of loose wires, too much wire, and the wrong wires set the stage for an electrical fire. Your electrician or HVAC technician can connect everything the correct way.
