10 Air Conditioning Myths That May Cost You More Money

Your AC works hard to keep you cool, especially during the summer heat. Unfortunately, many people get snookered by many air conditioning myths, causing them to spend money they shouldn’t. Let’s get to the truth of these myths to help you make informed decisions when running your air conditioner this summer in the U.S..

Myth 1: Your AC Unit’s Size Doesn’t Matter

One of the most significant untrue assumptions is that size doesn’t matter or it’s always best to choose the AC with the largest cooling capacity. The simple truth is an oversized unit can’t effectively remove humidity from the indoor air because it cycles on and off too quickly. This short cycling, in turn, causes more expensive energy costs.

Conversely, a small unit must work harder to cool a large space, resulting in a warmer home than you probably prefer, needless wear and tear and premature failure. For these reasons, you should always take into account your home’s square footage and other factors that impact the ideal AC unit size.

Myth 2: Cranking Down the Temperature Cools Your Home Faster

Oddly, setting your thermostat to a very low temperature doesn’t cool your home more quickly. Your AC works at a set rate and will reach each progressively lower temperature in the same amount of time, irrespective of how low you set the temperature. There’s no benefit to opting for an unnecessarily low setting, which only causes higher energy bills and reduced comfort.

Myth 3: Raising the Temperature While You’re Away Costs More Than Keeping It Steady

The perception that it’s cheaper to maintain a consistent temperature all day is a myth. The truth is, setting your thermostat 7-10 degrees higher when you’re not home for eight hours a day can save up to 10 percent on your cooling expenses. This is because your AC doesn’t have to work as hard to maintain a warmer temperature. Modern programmable thermostats automate this process, adjusting the temperature after you leave and before you return home to maximize savings without sacrificing comfort.

Myth 4: Running the Ceiling Fans 24/7 Keeps the House Cooler

Ceiling fans make it seem like a room is cooler, but they don’t truly lower the temperature. Actually, they work by blowing air onto your skin, generating a wind chill effect. That is why even though ceiling fans don’t cost very much to use, leaving them running in empty rooms loses needless energy. Use ceiling fans in occupied spaces to enhance comfort, but keep in mind you should always power them off when you leave.

Myth 5: It Doesn’t Matter Where You Install the Thermostat

Contrary to popular belief, the place you put the thermostat can significantly impact cooling efficiency. Installing it near heat sources like windows, lamps and appliances can trigger false readings, making your air conditioner work harder than required. The most useful location for the thermostat is a central location away from direct light and heat. You might even consider zoning your home with a number of thermostats for maximum comfort and energy savings.

Myth 6: It’s Fine to Only Change the Air Filter Once a Year

While some high-end media filters last up to a year, nearly all common air filters should be replaced every 30-90 days. Dirty filters reduce airflow, forcing your AC to work harder and use more energy. Alternatively, regular filter changes prolong the life of your unit and maintain efficiency.

Myth 7: Professional AC Maintenance Isn’t Important

Like any other home appliance, your cooling system should undergo scheduled maintenance to encourage optimal performance and longevity. Neglecting this can lead to undetected issues, causing troublesome breakdowns, high-priced repairs and premature replacements.

Myth 8: You Should Run Your AC Until It Breaks Down for the Final Time

You may hear this information about cars, but it isn’t true when you’re talking about air conditioners. About 10 years after installation, AC units often experience a major reduction in energy efficiency. While routine maintenance and proactive repairs can extend your system’s life span, you shouldn’t wait for a total breakdown to upgrade to a new unit. A scheduled air conditioning installation is more convenient and lets you tap into the next generation of features and performance improvements.

Myth 9: It Doesn’t Matter What HVAC Contractor You Hire

Hiring a contractor without doing your research could be a costly error. Always check the contractor’s certifications, guarantees and reviews to make sure you’ve found a business with the experience and skills to provide reliable service.

Myth 10: Working with a Small Business Is Always Better

While supporting local small businesses is commendable, this doesn’t necessarily mean they offer superior service. Larger, established companies often have more resources and a wide range of expertise to handle your needs efficiently.
