Choosing the Right Air Conditioner

Posted on

Purchasing and installing the right air conditioner is crucial towards keeping an energy-efficient, cool home. Install an AC unit that is too big and you can expect to see an increase in your monthly utility bills. Install a unit that’s too small and you won’t be able to effectively cool your New Jersey home.

Here’s what to look for when choosing a new air conditioner for your home.

Correctly Sizing an Air Conditioner

The size of your air conditioner is critical to its performance. Without a properly sized AC unit, you may experience:

  • Reduced comfort – An oversized air conditioner will cool your home faster than a properly sized unit. Although this seems ideal—think less energy consumed and lower energy bills—it doesn’t allow the water vapor passing over the condenser coils to evaporate, causing your home to feel more humid and not as cool.
  • Increased wear and tear – The more your system cycles on and off, the shorter your air conditioner’s life will be. An oversized air conditioner kicks on and turns off a lot more than a properly sized unit because it cools your home so quickly—sometimes only a few minutes pass between each cycle. Not only will this reduce the lifespan of your cooling system, but it will often mean more repairs.
  • More repairs – Because of the increased usage, your air conditioning system will need more repairs over the course of its life, causing you to waste money on a unit that could’ve been avoided had your HVAC company properly sized your air conditioner.

How to Determine the Proper AC Size?

Your air conditioner installer should be able to determine what size air conditioning system is right for your home. To receive accurate measurements and properly size your unit, contractors follow a load calculation protocol published by the Air Conditioning Contractors of America known as Manual J.

Manual J Load Calculation Protocol

A procedure that may be completed room-by-room or for your entire home, Manual J measures how much cubic feet per minute (CFM) each room needs for heating and cooling.

Manual J includes a variety of factors that affect your cooling load capacity, such as:

  • Surface type of your home
  • Square footage
  • Insulation levels
  • Windows
  • Doors
  • Ductwork location
  • Duct tightness
  • Infiltration rate
  • Internal loads (appliances, people, etc.)
  • Area your house is located in
  • And more

As a result of Manual J, each room is given a BTUH measurement of heat gained during the summer and allows your installer to properly size your air conditioner.
