Installing a new furnace can provide a major upgrade for your home's comfort and energy efficiency. However, many homeowners don't know what to expect on the day of installation. This guide will give you an overview of furnace installation by breaking the process down into three stages.
Stage 1: Initial Home Inspection
An HVAC contractor will need to visit the home before the day the new furnace is installed to perform an initial inspection. During this inspection, the technician will measure the physical space where the furnace will be installed and assess the existing gas lines, air ducts, wiring, and ventilation.
Contractors use load calculation testing to calculate the optimum furnace size for any home. Load calculation determines a home's heating needs using factors like the square footage of the home, door and window quality, and the type and quality of insulation.
Stage 2: Replacing the Old Furnace
Once inspection is completed and the homeowner has chosen their new furnace, the HVAC contractor will schedule a date for installation. Installers begin by shutting off the furnace breaker and gas lines, and then lay down tarps around your old furnace to create a work area.
Next, the furnace is disconnected from all gas lines, wires, ducts, and vents. Technicians can now remove the old furnace and install the new furnace on a rubber pad or other platform. The new furnace is checked with a level so that the fan will stay balanced while it is running.
Technicians may also need to build a duct add-on to connect the new furnace to the ductwork without any leaks or add additional wiring to power the new furnace. After all supply lines are reconnected and the duct connections are sealed with caulk, the unit is ready to be tested.
Stage 3: Testing the New Furnace
Quality HVAC contractors will subject every newly installed furnace to a battery of tests so that the homeowner can be sure their furnace is performing at peak efficiency. Technicians will measure air pressure, airflow volume, and temperature deltas throughout your home and make adjustments if needed. These steps can prevent problems like inconsistent temperatures, noisy operation, and shortened system life.
Furnace installation can usually be completed within a day, and the procedure should be minimally disruptive to your daily routine.
