Maybe you’ve decided that this is the year to replace your home’s air conditioning system. Maybe you’ve decided this is the year to increase your home’s comfort level, and save energy in the process. When it’s time to purchase a new air conditioner, spending the time to choose the right air conditioning unit is important; equally important is to to ensure the HVAC company you choose follows proper A/C installation practices.

Steps To Replacing Your Home’s Air Conditioning System

Steps To Replacing Your Home’s Air Conditioning System

To get the full benefit of a new air conditioning system, it’s important to make sure it’s properly installed.

Step 1: Choose the correct size
A HVAC contractor will first calculate your home’s cooling load and determine the right sized unit for your situation. Air conditioners are not one-size-fits-all equipment. Choose the wrong size and you’ll experience efficiency and comfort issues. If you choose an oversized unit, it will result in repeated on/off cycling that doesn’t give the equipment time to properly remove humidity or cool the home. Short cycles also put an added strain on the system, which in turn will shorten the equipment’s life span.

Step 2: Verify air flow rates
Air conditioning equipment specifies a range of acceptable airflow rates to ensure efficient operation. Once the equipment is in place, a contractor must make necessary adjustments to allow proper airflow through the system. Without it, your A/C equipment won’t cool your home as it should. Insufficient airflow over the evaporator coils also hinders the heat transfer, which can eventually cause damage throughout the system.

Step 3: Inspect the ductwork
The air conditioning unit is only one piece to your cooling system; your ductwork is equally important. Leaky, uninsulated ducts can lose up to 30 percent of the cooled air, which impacts both your environment and your energy consumption. To prevent losses, your HVAC contractor should inspect ductwork during installation and identify any issues that will cause your system to run in anything but an efficient way. All duct joints should be properly sealed, and covered with at least R-6 rated insulation.

Step 4: Check refrigerant levels
In order to have proper heat transfer in the condenser and evaporator, make sure your air conditioning unit has the proper amount of refrigerant for charging the system. Running the A/C unit with too much or too little refrigerant reduces the equipment’s cooling ability and increases energy consumption.
