When it comes to running your AC unit in the summertime, you want to be comfortable without spending a great deal of money. Did you know that the size of your AC unit could make all the difference when it comes to saving money during the hot summer months? Incorrectly sized units can harm your HVAC efficiency and could even lead to more costs associated with repairs.

The Importance of Unit Size

While size isn’t the only factor you should consider when installing a new AC unit, it’s definitely one of the most important considerations. Size affects how easily your entire home can be cooled and how it maintains efficiency.

Factors HVAC Contractor Considers

When it comes to properly sizing a unit for your particular home, our HVAC technicians consider the following things:

  • The total surface area of walls that will receive sunlight
  • Amount of insulation in your home
  • The volume of your home’s area (not the square footage)
  • The characteristics of the windows in your home (number, location, when they were installed, their overall efficiency)
  • The age of your home
  • Amount of shade your home receives from surrounding trees or shrubbery
  • The current state of your home’s existing ductwork

The Wrong Size Unit Will Give You Problems

If you choose not to consult an HVAC technician when deciding which unit size to install, you could risk hurting your wallet in the years to come. Don’t let a price tag or size fool you. Each home needs different units depending on all the factors mentioned above.

Too Big?

Bigger does not always mean better when it comes to your unit’s size. When you choose to purchase an extremely large unit you will not only pay more upfront, but you may pay for it in the future with both your comfort and your energy bills. While a large unit will quickly cool the air that needs to be circulated, it will not be able to cool your entire home. Once the cooling process is quickly finished, the unit will kick off, leaving uneven distribution in your home.

Not only will you be uncomfortable, but your unit will keep turning on and off because the thermostat is alerting it of the inconsistencies in temperature. Your energy bills will go up and your comfort will suffer.

Too Small?

If you opt for a smaller unit because of price reasons, you will end up paying more because of the incorrect size. A unit that is too small for your space won’t have the bandwidth to cool your entire home nor will it be able to maintain the correct temperature. Your unit will constantly run and you won’t even feel the cool air it’s producing

Determining the Right Size for Your Home

One of our HVAC technicians will happily help guide you when it comes to choosing a new unit. While size is a major factor, we will help narrow down unit choices based on your needs and home’s design.

Terminology

When it comes to unit sizing, there are two major components that differentiate units. Units are measured in tons. This is how units are sized based on the volume they can cool. One ton units can cool 12,000 BTUs (British thermal units) per hour. Two-ton units cool 24,000 BTUs per hour. So for larger homes, you would need more tons in order to cool the entire space.

The second classification is based on a unit’s SEER (Seasonal Energy Efficiency Ratio) rating. The higher the SEER rating, the less energy is used by your unit, which in turn saves you money on energy bills. When deciding on high-efficiency units, it’s best to go with the highest SEER rating that still fits in your budget. If you don’t want to compromise on efficiency, consider financing your new HVAC unit.
