Your HVAC System and Electricity Usage Myths That Will Drive Up Your Bills

Your HVAC System and Electricity Usage Myths That Will Drive Up Your Bills

Electricity is a part of almost everyone’s life. There are multiple reasons why it makes sense to reduce our consumption, so it’s little wonder homeowners chat about ways to keep the bills down. Here in Monmouth County, our climate dictates that we use equipment to treat our air — either heating or cooling it — for most of the year. Correcting electricity usage myths can result in some conspicuous year-round savings.

Leaving the A/C On

Many homeowners believe that turning the temperature setting of a central A/C down at the thermostat, but leaving it on all day, is cheaper than switching it off (then on again later). The “logic” here is that it costs more to cool down a hot house than to keep it moderately cool all day.

In fact, the feasibility of this old saw is dependent almost entirely on other systems within the home. If the structure and crawl spaces are effectively insulated, and if there are no air gaps and leaks, your home should retain the cooled air that you bought for the typical amount of time American homes are unoccupied.

Fan-Assisted Fallacy

Many people believe it’s a good idea to open the door of a room where a window A/C is located, then use a fan (or fans) to move the treated air around indoors.

In fact, just like your refrigerator, an A/C unit does not put cold into air; it takes heat out. Thus, it would be more beneficial to reverse the fans in this scenario, blowing hot air at the unit, not sucking cold air away from it.

A great many air-conditioning appliances are marketed as energy efficient, but a home is a complex construct of equipment, insulation and usage patterns. To get the most from the additional investment that’s usually required in purchasing an energy-efficient air condition, it must be accurately sized, properly installed and the function of other systems — such as ductwork — must be optimized. These are jobs for the experts. Across all of central New Jersey, you can contact Aggressive Mechanical Contractors to ensure you’re wise to electricity usage myths .
