Is Your HVAC Equipment Undersized or Oversized?

It’s a common misconception among HVAC contractors that the best way to provide sufficient heating and cooling for their clients’ needs calls for installing the biggest unit available that can fit the allotted budget. Similarly, other HVAC teams end up fitting a home with a system that is much too small. You might be wondering, is there a perfect hvac equipment size for my home?


How the wrong unit size will affect your home

Both scenarios would result in heating and cooling inefficiencies, and consequently, the discomfort of the entire household.

A unit that is too big is prone to short-cycling, which means it is constantly turning on and off — and this happens before the unit can effectively heat up or cool down the area.

On the other hand, HVAC equipment sizes that are too small will often be kept running for prolonged periods of time, but will never be able to fully achieve a comfortable temperature for the space.

In both situations, the inappropriately sized HVAC unit causes the household to waste significant amounts of energy and money — too much power is being used by the unit, which racks up higher energy bills, even if it fails to properly cool and heat the home.


Identifying the problem

As a consumer, you must be asked this important question: Is your HVAC equipment undersized or oversized? Determining the answer makes it easier to identify whether a change is in order so you can begin reaping the right benefits from your HVAC system.


Arriving at the right solution

Reliable, experienced HVAC contractors know that the only way to determine the correct size of a heating and cooling system for a particular space is to perform the ACCA Manual J8 load calculation. This method enables HVAC specialists to compute the necessary heat loss and heat gain for the home.


When you commission a trustworthy local HVAC team to perform the calculation, the following crucial parameters will be analyzed:

  • Where is the house located?
  • How hot do summers get in your location?
  • How cold do winters get in your location?
  • What kind of windows are installed throughout the house?
  • What direction is your home’s front door facing?
  • What kind of wall and ceiling installation do you have installed?


Heating and cooling contractors who routinely and effectively perform the ACCA Manual J8 load calculation demonstrate that making accurate computations based on a thorough assessment of the property should be the only method for choosing the right systems. Thanks to this process, your home will be fitted with a system that is sure to last many years and that will provide the correct heating and cooling levels that will ensure maximum comfort within the home during all those years.
