The Truth Behind Common HVAC Myths

Take correct decision for your home by knowing the difference between facts and myth.

With April Fools’ Day around the corner, practical jokes and hoaxes are par for the course.But be wary of the myths and misconceptions that are perpetuated all year round about the HVAC industry. From convenient half-truths to gross inaccuracies, a lot of this information has been accepted as fact. Unfortunately, these falsehoods harm the industry, and the worst part is, they mislead homeowners in areas like Phoenix and Tampa where air conditioning is essential for keeping fit and healthy during the summer months. You must separate fact from fiction to avoid getting played for a fool. Check out some prevalent HVAC myths below:

AC Air Filter Myths

Air filters remove allergens from indoors, thereby improving the air quality and promoting a healthy lifestyle.

Myth: Homeowners Can Change Air Filters Without Professional Help

Due to their hectic lifestyles, people nowadays rarely have the time to inspect or change AC air filters regularly. And, even if they do manage to clear them on schedule, there is no guarantee that the homeowners will replace the air filters correctly. Perhaps they chose the wrong product, or the fitting was loose. Either way, improper installation not only hampers the performance of your cooling unit but does extensive damage to your system.

Myth: You Don’t Need to Replace AC Air Filters Frequently

Just because you get your AC serviced annually, doesn’t mean you can bail on replacing the air filters more frequently. Ideally, you should switch out the existing air filters in favor of new ones after a span of 30 to 90 days, depending on the factors like usage, household size, the presence of pets, and so on. Remember to inspect the filter on the first of every month by holding it up to the light. If no light shines through, that means your filter is clogged and dirty, and you should change it as early as possible. Otherwise, you will face problems like poor indoor quality and even premature as your unit will fail to push air easily and increase the strain on your AC.

AC Operation Myths

States, such as Texas and Florida, experience intense heat and humidity. Residents must keep their ACs switched on for the better part of the day to stay sufficiently cool. But several myths persist regarding AC operations.

Myth: Switch Off the AC When You’re Not Home

Yes, but this holds true only for places that register low heat and humidity levels. Areas of Florida stay warm and humid year round, which means turning the AC off while leaving, and starting it back again after a few hours may cause your air-conditioner more harm than good. That is why, in places like Tampa, you need to leave your AC running before heading out. This enables the cooling unit to reduce the indoor temperature and humidity within a reasonable amount of time.

Myth: Turn On the Fan in an Empty Room for Faster AC Cooling

A fan does not lower the room temperature; rather, it circulates the air over your skin and lowers your body temperature, making you feel cooler in the process. So, if you leave the fan on when exiting the room, you’re only wasting energy. So, use ACs and fans only when someone is present in the room.

Myth: Set the Temperature Below the Desired Level to Cool Your Room More Quickly

Suppose you want to lower the temperature of your home to 70 degrees Fahrenheit. Setting the temperature to 65 degrees won’t make the system cool faster. That’s because AC units are designed to operate at a consistent rate. Once it achieves the correct temperature, it simply switches off. So, if you reduce the temperature to the maximum possible limit, you’ll probably end up with a frigid home if you fail to readjust the thermostat when you hit a comfortable temperature, wasting energy and money in the process.

AC Vent Myth

AC vents streamline the flow of air in your home and allow the unit to cool your home more efficiently.

Myth: Save Money by Closing the Vents in Empty Rooms

A lot of homeowners believe that blocking the AC vents in an empty room prevents cool air from cooling other rooms unnecessarily. However, closing the vents does more harm than good. The unit works harder, consumes more electricity, and eventually, the whole system is thrown off balance. As the pressure builds up in the ductwork, leaks and other issues occur. In extreme cases, the equipment might break down entirely thanks to increased wear and tear. If a particular room does not require any cooling, get a separate thermostat for that area. Do not try to cut down on your energy bills by skimping on adding an extra zone in your home. You might end up paying more in the long run.

AC Size Myth

The AC in your home might struggle to keep your home cool during the hottest days of summer, prompting you to consider a bigger and better cooling unit.

Myth: Buying a Larger AC Offers Better Results

Homeowners mistakenly believe that a bigger AC is the solution to their cooling issues. Actually, these systems function more effectively and efficiently when they are compatible with the different aspects of your dwelling, including insulation level, the direction of the windows, placement, square footage, and so on. Regular maintenance is also required for peak AC performance. If you buy a newer, larger AC model and neglect it, then you will face similar problems.Plus, ensure your AC is not installed in a spot that receives direct sunlight; there should be sufficient shade. Leaks and cracks around your home also allow cold air to escape, thereby preventing the temperature in your room from reaching the desired level. The best course of action is to ask the AC personnel to perform a Manual J-Load Calculation – a procedure that involves multiple variables to determine the right sized air conditioning system for your house.

Beat the summer heat with the right air conditioning unit in Tampa, Las Vegas, and other warm places around the country. The residents need ACs to stay cool and comfortable, and they cannot afford to be swayed by wrong or misleading information.So, if you hear some ‘interesting’ tidbit about air conditioners, verify the same with your local air conditioning expert. These people possess the knowledge and experience to differentiate between myth and fact, and they will help you take the correct decision for your home.
