At Logan Services our main priority is ensuring our customers are comfortable in their homes. This means finding the perfect HVAC system for your home, starting with determining the right sized equipment. To choose the best system combination for your comfort needs, we need to do a load calculation.
A load calculation, a well-known concept in the HVAC industry, is a method of computing heat gain and loss in your home. The result of your home’s load calculation will help us to correctly size the heating and cooling equipment that will be best for your living space.
What Measurements We Take During A Load Calculation
When a Comfort Consultant comes to your home for a free in-home estimate, they will take specific measurements when looking at the existing heating and cooling system. Some of the measurements you will see us take that determine the correct size of HVAC equipment includes the following:
- Square footage of the home, along with home layout and ceiling heights
- Type of foundation
- Type and number of windows
- Type and number of doors
- Insulation & ductwork
- Skylights & fireplaces
- House orientation (the way the house faces – north, south, east and west)
- Number of people living in the home
Why A Load Calculation Is Important
Our team will do a thorough analysis of your home. A load calculation is essential to determine the correct HVAC system type and size. When our Comfort Consultant takes measurements in your home, we will discuss your comfort concerns. Depending on the concerns you tell us about, it could point to under or oversized heating and cooling equipment. The wrong size of HVAC equipment can make you uncomfortable and may not allow your system to heat/cool your home adequately.
The Customer Benefits Of Load Calculation
The benefits of doing a load calculation in your home will ensure that we find the correct size of HVAC equipment to install to ensure your comfort. In addition, taking these measurements will help us understand what size of equipment is required to heat and cool your home correctly.
- Too small of an HVAC system will constantly run, increasing energy consumption.
- Too small of an air conditioner – the home won’t cool down properly
- Too small of a furnace – the home won’t warm up properly
- Too big of an HVAC system will shorten the life of your heating/cooling equipment and increase your utility bills.
- Too big of an air condtioner – won’t run long enough to remove humidity
- Too big of a furnace – will leave uneven temperatures
Units Of Measurement For HVAC Sizing
After we perform a proper load calculation, you will be informed of the sizing of equipment needed for your home. Those sizes will be shared with you in the form of BTUs (heating) and Tons (cooling).
Furnaces Are Sized Based On BTUs:
Your furnace size will be measured in BTUs (British Thermal Unit). The most common furnace BTU sizes include 60,000, 80,000, 100,000 and 120,000.
Air Conditioners Are Sized Based On Tonnage:
When it comes to your outside unit, whether you have an air conditioner or heat pump, your equipment will be measured in tons. Contrary to popular belief, the tonnage of your air conditioner has nothing to do with its weight. A ton is a term that describes how much heat the AC unit can remove from a home in one hour. Your load calculation will determine what air conditioner tonnage you require, which can range from 1.5 tons to 5 tons.
