There are many myths regarding how best to use and maintain a cooling system like an evaporative cooler or air conditioner. Unfortunately, these myths aren’t just wrong; they can lead to premature wear and tear on your system and even increased energy costs. Here are three common myths that should be dispelled.
1. Turning the Thermostat Down Really Low Will Cool Your Home Faster
While it may seem counter-intuitive, turning your thermostat down really low will not help you cool your home down any faster than turning it down just slightly. This practice can even be harmful and increase your energy costs. Turning the thermostat down much lower than the temperature you want forces the system to continue running longer than necessary. Your thermostat only tells your cooling system to turn on or off based on the temperature in your home; it won’t make your system run “harder.”
2. Swamp Coolers Are the Same as Air Conditioners
While more energy efficient and affordable, swamp coolers operate very differently than air conditioners and are only suited for specific environments. In fact, swamp coolers won’t even work in humid areas. They also require a constant water source and routine maintenance. Evaporative or swamp coolers are also unable to bring the temperature down as far as an air conditioning unit is able to reach. While an air conditioner works like a refrigerator and draws moisture out of the air, swamp coolers work by introducing moisture into the air in your home to increase humidity and comfort.
3. Closing Air Vents Can Save You Money
When you’re interested in saving on energy costs, you may consider closing air vents in rooms you aren’t using. It seems like a great idea; why pay to cool rooms you aren’t in? Unfortunately, this is a bad idea that won’t have the intended effect. When you close air vents, the first thing you’ll cause is a build up in air pressure in the duct system. This actually puts more strain on your air conditioner which is designed to cool your entire home. This can lead to any or all of the following:
- Air conditioner coil freezing
- The growth of mold as a result of increased condensation
- A broken compressor
- A rise in air duct leakage
- Lower airflow if you have a PSC blower
- A cracked heat exchanger, leading to potentially dangerous levels of carbon monoxide
