2 Ways To Prepare Your Home For A New Furnace

by Celina Simpson

After experiencing a cold home throughout the majority of the winter season, you've discovered the hard way that you need a new furnace. Your current furnace either didn't produce enough heat or developed several malfunctioning components over the past couple months. However, before you install your new furnace, you'll need to make a few preparations. Ensure that your new furnace operates safely and efficiently by performing or arranging for these two tasks:

Clean Your Air Ducts

If your central heating system is also connected to a central air conditioner, then chances are mold has grown inside your air ducts.

Your air conditioner's evaporator coil, the large, metal component that cools the air passing through your air conditioner, releases a large amount of condensation while active. As air passes through your coil and becomes humidified by the condensation on your coil, your air ducts can become coated with moisture—which creates a perfect environment for mold growth.

Once mold begins to grow, it will release spores that spread rapidly throughout your air duct system and into your home. If the mold isn't removed, then it will significantly decrease the quality of your indoor air. Although it's not a very common occurrence, severe mold growth can cause respiratory damage to you and the other members of your home.

However, mold isn't the only contaminant in your air ducts. As debris slips through the pores of your air filter and unsealed gaps of your furnace housing, it will pass through your furnace and enter your air ducts. When these contaminants are present in your ducts, they'll severely affect members of your household who suffer from allergies.

The majority of your air duct system is buried deep within your walls. Since there are only a limited number of access points in your ducts, it's best to leave the task of cleaning and purifying your air ducts to your local HVAC technician from a site like http://www.avisac.com. Although it may be possible to partially clean the duct space near your access points yourself, you won't be able to eliminate the entirety of the mold growth or debris in your duct system without the specialized equipment used by HVAC technicians.

This problem won't go away after you install your new furnace. Arrange for annual duct cleanings to prevent mold or debris from collecting in your ducts in the future.

Measure The Volume of Your Furnace Room

Your new furnace must receive a large volume of air to efficiently heat your home. However, your furnace's air supply is limited by the room in which your furnace is installed. If there isn't enough air in your furnace room, then your furnace will suffer from severe airflow restriction.

One of the problems caused by an insufficient air supply is overheating. When your furnace's combustion chamber overheats, your heat exchanger will quickly become fatigued. Metal fatigue will cause small cracks to form in your heat exchanger—and since your heat exchanger is responsible for ventilating combustion fumes out of your home, a crack in your heat exchanger will allow carbon monoxide to contaminate your indoor air.

You can prevent airflow problems in your new furnace by determining the available volume of air in your furnace room. Measure the width, length, and height of your room. Multiply these numbers by each other to calculate the volume of your air supply. For example, a room with a width of 12 feet, a length of 15 feet, and a height of 10 feet will have 1,800 cubic feet of air.

Locate the CFM rating (cubic feet per minute) of your replacement furnace on the furnace's specification sheet. If your air supply is greater than your furnace's CFM rating, then you won't have to select a different furnace. However, if your air supply is less than your replacement furnace's CFM rating, then you'll need to either modify your furnace room or select a different replacement furnace that requires a smaller volume of air.

If you have trouble calculating your air supply, then hire your local HVAC technician to perform the necessary calculations for you. If you calculate your air supply incorrectly, then you'll end up with inefficient heat production even after you've installed your new furnace.
