Finding the Right Size of an HVAC Unit
When it comes to HVAC units, bigger isn't always better. Choosing a suitably sized cooling unit for the home determines how efficiently the device operates and prevents unnecessary energy costs. A device that's too large will cause a different set of problems from one that's too small.
Let's take a closer look at the reasons why size matters:
Comfort level
An HVAC unit not only cools the room but is also a dehumidifier that removes moisture from the air. That's what gives an air-conditioned room that crisp feeling on a hot summer day.
It takes longer for the appliance to dehumidify the space than to cool it. An oversized HVAC unit will quickly cool the room and shut off before adequately dehumidifying the space. This imbalance causes the machine to turn on and off frequently, consuming more energy.
The short burst of cool air released doesn't allow for air to circulate through the entire house, meaning that it doesn't get to pass through the air filters. This means that a larger HVAC unit doesn't remove pollutants from the air resulting in lower air quality in the home.
Wear and tear
A bigger than necessary HVAC unit will operate in short cycles where it constantly turns on and off. This frequent adjustment puts additional strain on the motor, shortening its lifespan. The appliance will require more recurrent repairs and will generally not last as long as a better-sized unit.
Runs constantly
An HVAC unit that is too small constantly runs to keep up with the cooling and heating needs of the house. Even when the appliance operates at maximum output, it will still lack the power to regulate the house's temperature correctly.
Therefore, a smaller HVAC unit results in higher energy bills and a not sufficiently cooled or heated home.
Finding the right-sized HVAC unit
An appropriately sized HVAC unit will manage to cool the home and remove moisture from the air during its cooling cycle. It will then shut off until the room begins to warm up again. This efficiency provides optimal comfort levels while saving on energy costs.
There are several factors to consider when searching for the right-sized HVAC unit for the home. A homeowner needs to look at the property's square footage, ceiling height, type of windows, type of insulation, the climate, and even the color of the roof.
Time to call the professionals
Picking an HVAC unit can get confusing with so many aspects to consider. This job is best left to industry experts who can assess the property and make the right decision for the home. When selecting an HVAC unit, reach out to a licensed technician.
