What Size HVAC System Do I Need?

As you shop around for a brand new air conditioning system, there is one essential question you need to ask: "What size air conditioning or furnace system do I need?" It's very important to get the most appropriately sized air conditioner for your home or your maintenance costs will be negatively affected over the lifespan of your HVAC.

What Does HVAC Size Mean?

HVAC unit sizing does not refer to the physical measurements and size of the unit, but the sizing refers to the HVAC's capacity to cool or heat an area effectively. Dimensions are measured in tons, however, tonnage does not describe the system's weight as expected. Tonnage, in the context of HVAC systems, refers to the capacity to heat or cool a residence effectively and efficiently. The tonnage of an HVAC system is the quantity of warmth the system can eliminate per hour to cool the residence.

Why is it important to Get the Right Size System?

When you figure out the right dimension system your residence requires, it is crucial to stick to this dimension when you purchase your new device. HVAC units are not one-size-fits-all, and it's not advisable to size up or down to locate a better fit as you would with other gadgets and devices. The dimension of your device directly impacts the amount of energy it consumes, how it operates, and the comfortable temperature inside your house.

If you purchase a unit that is too small for the residence, that unit won't have enough capacity to keep rooms at comfortable temperature levels. The system will run for longer periods as it attempts to offset its shortcomings, using an excess of energy. An HVAC system that runs for longer periods will have an increased deterioration rate, which will trigger extra breakdowns, and a faulty system that requires repairs more often.

A larger unit won't maintain a comfortable temperature in your residence if it's not the appropriate sizing for your space and needs. With excess capability, the HVAC device will still be able to cool or heat but will fail to do so at a moderate and consistent rate. The cycles will be too short and will cause damage to the device and thus decrease the otherwise long life span. The short cooling cycles cause the temperature to fluctuate which leads to your home not being at a consistently comfortable temperature.

What Sized HVACE Do I Require?

The best way to find out what accurate dimension HVAC your residence requires is to seek advice from a certified HVAC technician. Many factors contribute to determining the ideal size HVAC unit for a residence - it's not just the size of the space. Many elements impact the homes requirements, these consists of:

• Square footage
• Number of stories
• Ceiling elevations
• Number of windows and doors
• Insulation degrees
• Building materials
• Number of residents
• Residence's orientation

These elements are factored in when a professional HVAC technician executes a hand-operated J Load estimation, which displays the home's cooling load. This estimation indicates the amount of BTUs of heat are required to be removed from an area per hour, so you'll know the appropriate capacity your home or residential room needs from an HVAC system.
