Your reliable HVAC will eventually have to be replaced, as it will die out altogether or become too inefficient. Installing an HVAC is something that should only be attempted by a licensed HVAC professional. This is not a job for even the most ambitious do-it-yourselfer. This installation requires considerable knowledge of electrical work, sheet metal work, and some plumbing work. Installing a new furnace is a somewhat complicated process, and only licensed Dallas Plumbing & Air Conditioning professionals.
If you are switching from an electric furnace to a gas furnace (or vice versa), the project is even more complicated. Dallas Plumbing & Air Conditioning Company technicians undergo rigorous training after completing their Associates Degree and are trained to handle any contingency that comes up during the installation process.
The Installation Process
All gas and electrical must be turned completely off before any work is started. Leaving power or gas to the furnace unit on while uninstalling it is extremely dangerous and is not recommended under any circumstances. Once the utilities are turned off, it is safe to remove the old furnace. All gas supplies and wires need to be disconnected, and ductwork and vent pipes should be detached and removed. The Dallas Plumbing & Air Conditioning Company professional who removes your HVAC will be wearing gloves and protective gear to avoid any injuries.
If your existing furnace is connected to your AC unit, the connection will also have to be disassembled. Once the unit has been completely dismantled, and all the screws have been taken out of the base, the old furnace can be hauled out and recycled or discarded properly.
Preparing the Area for the New Furnace
The next step for the technician will be to thoroughly clean the area where the new furnace will be installed. If there is any dust in the area, it must be vacuumed up. You don’t want to spend all that money on a new furnace just to let it be contaminated with dust when you have it installed.
Once the area is entirely free of dust and debris, it is time for the technician to start installing your new unit. The pipes, wires, and ductwork will be connected to the new furnace. After that, the technician will connect the thermostat and turn the gas and power supplies back on. Now the technician can test the system and check the ductwork for leaks.
If you’re having a gas furnace installed it must also have all the gas supply lines inspected for leaks. All connections, even those to the AC unit must be checked. The system itself must also be carefully examined for carbon monoxide leaks and other gas emissions, which again, is something that must be done by an HVAC professional, as it requires specialized knowledge and equipment.
Leave it to the Professionals
As a homeowner, you should choose what type of furnace will best suit your needs. Once you select your unit, the rest should be left up to the pros. Removing your old HVAC and installing the new one is a big, dangerous job, and there are a countless number of ways it can result in serious injuries or expensive repairs.
