Instructions
Follow these steps to ensure that you’re installing HVAC ductwork properly.
Step 01: Calculate The Heating And Cooling Loads For The New System To Be
Installed.
Finding the right-size HVAC unit is crucial since it can determine whether a home feels
cozy or stuffy. A unit installed in the wrong size results in premature wear and tear, a
shorter system lifespan, higher energy costs, and varying temperatures throughout the
house, depending on the season. If you’re taking measurements, try to be as thorough as
possible. A skilled technician should perform load calculations by gathering the proper
information before offering a recommendation. Always determine the home’s Heating
Load Worth (HLW) as the first step in an installation. This calculation considers the
home’s location, age, size, building materials, and any adjacent trees and sun exposure.
Step 02: Examine And Improve The Present Ductwork
The HVAC systems must be in good working order, given how expensive they are. First,
examine the ductwork for any damage or obstructions to airflow. Remove all obstacles,
most of which may be found at outflow and information registers, also known as sends
and returns.
Before further maintenance, such as cleaning, look for leaks and fix and seal any trouble
spots. Even with the most significant unit, an HVAC system won’t operate at its best
without well-sealed ducts and sufficient insulation surrounding it. By lowering energy
expenditures and assuring correct operation, these elements increase efficiency.
Repairing an existing system could be one method of the system upgrade.
You might prefer a ductless heating and cooling system, which connects indoor registers
with outdoor heating and cooling units by simply drilling holes in the walls.
Whether you’ve picked an indoor or outdoor system, pick a location for your unit. It
would be best if you performed a complete site assessment before marking (with chalk or
spray paint) where you want the unit to go. When determining the positioning, take
accurate measurements (measure twice, cut once).

Step 03: Setting Up The Device

The majority of contemporary units are wall-mounted. However, if you’ve decided to
create a new duct system, we advise you to adhere to the instructions provided with the
unit. This straightforward solution is required due to variation among current producers
and others who might offer products in the future.
Before grabbing any tools, consider the previous procedures, whether you’ve decided on a
wall-mounted system or a more challenging full-house system. Always adhere to
manufacturer recommendations to ensure proper operation and preserve the warranty.
Step 04: Check To See If The HVAC System Is Functioning Correctly.
Up to 30% of performance loss might be caused by an HVAC system that has been
installed improperly. Before turning on any brand-new HVAC, you should perform a
thorough inspection, including listening for any odd noises and verifying that airflow and
temperature are uniform throughout all rooms. To learn the best ways to take care of your
new equipment, perform some basic maintenance tasks.
HVAC Safety Risks That Every Homeowner Should Be Aware Of
At the electrical circuit-breaker panel—the gray box in a closet that once included fuses
but now only involves flipping switches—turn off the electricity to the circuit that services
your HVAC system. Before touching anything connected to the circuit, you can check to
see if any current is still flowing through that line with a multimeter approved by an
electrician.
Exposure to hazardous substances, such as some refrigerants, is one of the significant
causes of HVAC mishaps. It is necessary to obtain thorough safety training before working
with these compounds. Certain compounds can result in severe burns or other wounds.
You can handle chemicals more safely if you thoroughly understand each one.
Manufacturers may call some refrigerants “safe,” but they could still be dangerous if they
come into contact with the heat of any kind, such as heat from the sun, heat from an
electric heater, or even heat from the human body.
Be ready for any mishap that might occur. Don’t cut corners to save money. Give your
tape measure and gloves to certified HVAC technicians if you’re over your head.
