Furnace Installation Checklist

furnace installation checklist

We need furnaces to keep our homes comfortable during cold weather. It keeps houses warm by moving air, steam or hot water. And because they generate a lot of heat, a furnace can pose risks when not installed correctly. Ensure the furnace contractor you hire follows stringent guidelines during the furnace installation to ensure that it stays safe once you start using it to safeguard you and your family’s health and life.

The following is a checklist of the various considerations to be observed when replacing your furnace:

  1. Load calculation–contractors should carry out a load calculation to find out the heating and cooling requirements of your home. Some contractors take the size of your home (in square feet) as the basis for your heating and cooling needs. But this is a wrong practice. It will not yield the right information on your home’s actual total load.
  2. Replacement – it is not advised to change any furnace parts with a similar part since there is a likelihood that the original ones weren’t correct in the first place.
  3. Ventilation –you can still use an old ventilation system as long as it matches your newly installed furnace. When working around blower-type furnaces, you will need a minimum of 2 square inches to match every 1,000 BTU. With every other furnace, you can make do with just two combustion registers.
  4. Garage furnaces –you should observe at least 18 inches of height elevation from the garage floor surface until you reach the point of ignition. Also, remember to place your furnace away from the path that leads to your garage.
  5. Restricted areas –do not install a gas furnace in places such as the bedroom, bathroom, and closet. Moreover, take note that when installing the furnace in the attic, ensure there is, at least, five feet of space between the floor and the ceiling as well as a 30”x30” space within 20 ft. of the furnace.
  6. Underfoot furnaces–Install it nearby a light switch so you can turn on the light and see well while installing. Meanwhile,position a suspended furnace about 6 inches away from the ground.
  7. Inspection–for the purpose of installation inspection done by a building inspector, make sure the contractor leaves behind the installation description. They will also likely check your chimney to verify whether it complied with the standard 350°.

Look for licensed, fully bonded and insured heating contractors for any routine furnace installation, so you have the guarantee of safe and efficient installation, and a no-fuss system onwards. If you chose a top of the line furnace, working alongside a contractor who offers a warranty on the work they did is vital as well. Most of the time, furnace manufacturers offer a lifetime warranty on heat exchangers and a five-year warranty on parts. There are even some who offer money-back guarantees. It’s a win-win situation for you then. Investing in a furnace, as well as a good and professional furnace installation is non-negotiable if you want to have a furnace that can provide sufficient heat to your home for a long time without any hassle at all.
