Determining your HVAC system’s load is the first step if you plan to buy an HVAC in Saugus, MA. This will assist you in selecting the suitable size and kind of HVAC system for your residence. You shouldn’t walk into a store and buy a system that seems reasonable if you don’t know its specifications. To determine the right size, use a load calculation tool or have a professional do it.

Once you’ve determined the load of your HVAC system, you can start looking at different types of systems available. When selecting equipment, it is advised that you consider factors such as energy efficiency, noise levels, and cost to make a well-informed decision. Researching the different brands available in your region is crucial to ensure you purchase a reliable product.

Why Bother Calculating the HVAC Capacity?

Many homeowners might not consider the load factor when buying their first HVAC. Still, technicians rely on the calculations to get your home the required air conditioning. It’s the energy-efficient way!

If you buy an HVAC with an oversized capacity, you might get a cooler room, zones, or spaces sooner. But that will strain the thermostat prematurely. That results in short cycling and excess wear & tear for the unit. Soon, you might need our technicians for your flailing HVAC in Saugus, MA!

Estimating The HVAC Load & Tonnage

For this chill-filled activity, you need a measuring tape, a notepad, and a calculator (you’ll have it on your phone).

Step One: Measure the Space | HVAC In Saugus, MA

Measure the length & width of each room you intend to cool & multiply to get the square ft area. Add them all up to have the house’s entire area. Remember to measure the ceiling height, too, as it will be helpful later.

Step Two: Start Counting

Count the number of exit doors & windows in your home & the number of occupants. For every count, you have to consider the following.

Per Occupant: add 100 BTUs
Per Door: add 1000 BTUs
Per Window: add 1000 BTUs

Step Three: Calculate

Suppose you are one of 3 occupants-square-foot house with 12 windows & 3 exiting doors, and ceilings as high as 10 ft. In that case, here is how you would calculate the HVAC load.

Base BTU = (house area in square feet * height of the ceiling in feet)Occupants = (no.of occupants * 100)

Door = (no.of exit doors * 1000)

Windows = (no.of windows * 1000)

Total BTUs = (Base BTUs + Occupants + Door + Windows )

Given 1 ton HVAC = 12,000 BTUs/hour

HVAC Rating = (Total BTUs)/12,000

So, for the values given above, the HVAC rating should be:

Base = 25,000

Occupants = 300

Doors = 3000

Windows = 12,000

Total BTUs = (40,300 BTUs)/12,000 = 3.35 tons ~ 3.5 tons
