Have you ever wondered what goes into a heating or air conditioning system for a large office building or another large building like a mall or a school? My name is Evelyn, and I am an HVAC architect. I design heating and air conditioning systems for large, corporate buildings. Making sure that a large building with many rooms or offices is efficiently heated and cooled is a very large job and is much more complicated than simply heating or cooling a home. This blog will educate the reader on how heating and cooling jobs this large are designed and completed.
Even the most efficient air conditioning units use a bundle of electricity. If you want to keep your cooling costs under control, it's essential to do all that you can to keep warm air out of the home and optimize your AC use. Here are a few simple tips to help you achieve these goals.
Install reflective window film.
Even if you have new, well-sealed windows, the sunlight shining through them will warm your home and make your air conditioner work harder. This can be minimized if you take the time to apply a reflective film to your windows. Available at most home improvement stores, this adhesive film can be applied in a few minutes – you just peel off the paper backing, and smooth it on. It will reflect sunlight rather than letting it shine into your home.
Plant shrubs on the sunny side of your home.
Usually, the east and west sides of a home receive the most sunlight. Planting shrubs or bushes along these sides of your home will help reduce your heating costs in two ways. First, it will block warm sunlight from shining directly on the walls of your home. Second, the shrubs will work as an extra layer of insulation, keeping the coolness inside.
Upgrade to LED bulbs.
Regular, incandescent light bulbs give off heat, causing your air conditioner to work harder to cool your home. LED bulbs give off less heat. As an added bonus, LED lights themselves use less electricity than incandescent ones, so your energy bill should decrease even further.
Make sure nothing is blocking your AC vents.
If you have furniture in front of your AC vents, your air conditioner may not be able to circulate air properly, and it may have to stay on for longer in order to cool your home. Pull any furniture away from your AC vents and air returns. Double check that vents are open in any room you want to be cooled, too.
Change your AC filter regularly.
Failing to change the filter is a common mistake among homeowners. Your blower unit has to work a lot harder to push air through a dirty filter than a clean one, and letting the filter get dirty can also cause dust to build up on the condenser coils, lowering the efficiency of the unit. Change your filter every month during the cooling season, and you'll notice a decrease in your energy bills.
If your energy bills are still very high after following these tips, speak to your HVAC professional. There's a chance your unit needs some maintenance in order to operate more efficiently.
