Homeowners are always looking for creative ways to lower their utility bills. Unfortunately, there are many urban legends and falsehoods about how to efficiently cool a home that may be actually costing you money. This article will seek to debunk 3 popular air conditioning myths so as to help you achieve energy-efficient cooling this spring.

A bigger AC will provide better air conditioning

There is a misconception that a bigger AC unit will actually help cool down your home faster more effectively. This couldn't be further from the truth, as your AC needs to be correctly sized for the space you intend to cool.

If you purchase an AC that is too big for your home, it will cool the space but fail to remove humidity properly, leading to a home that is damp and clammy. A unit that is too small will struggle to cool the home and thus run continuously, which could cause energy wastage and over-drying of your air. An HVAC contractor can advise you on the correct AC stipulations for your home so you can achieve energy-efficient cooling and maintain ideal indoor humidity conditions.

Where the AC is installed doesn't matter

Like size, the location of the AC unit can greatly affect how effective your air conditioning is. Placing air registers near heat-emitting appliances such as television sets, computers and lights can lead to energy wastage, as the thermostat will sense the increased heat and cause the unit to run for longer than necessary.

Similarly, be sure to remove shrubs and trees near the outdoor heat exchange, as they can obstruct the flow of cool air into the unit and cause the AC to work harder.

Closing air registers can redirect cool air where you need it

Some homeowners try to block air vents and registers in unused parts of the house in hope of redirecting conditioned air to parts of the house that are used more frequently.

This is a home energy falsehood that can increase your utility bills and potentially damage your AC unit. Forced air AC systems work on a delicate pressure balance that allows the unit to suck up hot air, cool it and redistribute it throughout the house.

Closing off any vents can disrupt this balance and affect how the AC takes in and redistributes air, causing the unit to work harder to cool your house. Furthermore, blocking air registers can disrupt the de-humidifying effect of your AC in unconditioned areas on the house, leading to moisture problems.
