Don’t Believe Those HVAC Fake Facts! Check These Out…

When it comes to purchasing a HVAC be sure go to a reputable technician. There are many HVAC myths that simply will not go away. Unfortunately, with any specialized industry, there are a ton of heating and cooling myths circulating and sometimes it’s hard to separate fact from fiction. Below are some of the most common HVAC myths and some truths to dispel them.

Air Filters Do Not Need to Be Changed on a Regular Basis

Over time, dirt, dust, and moisture block air filters. Though a variety of air quality factors affect how quickly, generally the dirtier they get, the less efficiently your equipment will run. Not only does this mean trouble down the road, it can have a big impact on your budget. One HVAC myth you absolutely need to dispel is the idea that you only need to change (or clean) your air filter once or twice a year. Air filters absolutely need to be changed on a more regular basis. During low-use months, you may be able to wait 2-3 months before having to replace your filter, but don’t forget to at least check its status every 30 days. Wait no longer than 90 days to clean or replace it.

Duct Tape is a Good Solution For Sealing Air Ducts

Duct tape can have a negative impact on the system because it can cause dust build-up. Duct tape doesn’t last very long and you’re at risk for air leaks once the tape falls off. Mastic sealant or aluminum foil tape, also known as HVAC foil tape, to seal the gaps and cracks serves as a better seal and insulator. A tightly sealed duct system is extremely important for the health and efficiency of your home. Unfortunately, there will always be parts of your ductwork system that are inaccessible or dangerous to reach. If you suspect leaks in your duct system, schedule a technician to take a look at your system.

A Thermostat’s Location Does Not Affect the HVAC

Thermostats read the temperature of the proximal location where they are installed. If a thermostat is located near a heat source such as a very sunny window then it may provide an inaccurate read of the overall environment. As a result the system may be unnecessarily overcompensating—which is not only expensive, but often uncomfortable.

The Bigger the Unit, the Better the Results

When it comes to air conditioning, don’t assume that size is everything. Purchasing a bigger system could mean that you’re wasting your money. Instead of upgrading the size, think about purchasing an efficient, newer unit. Also, make sure that you’re getting tune ups — a clean air conditioner will always run more smoothly and last longer than one that you fail to maintain. Every home needs a properly sized cooling system. In fact, if the unit it too big for the home, not only will installation and operating costs be higher, it won’t even function properly. Common issues are frequent on and off cyclings, high humidity, and poor air distribution. A correctly sized unit will offer your home the perfect level of comfort. The HVAC technician who performs your replacement or installment services should inspect your entire home to ensure you are getting the right-sized unit. It’s an investment worth sizing right!

Close the Vents and You’ll Save Money

Closing a vent in a room will not save money. It will eventually throw off the system’s balance and potentially lead to other issues such as leaks caused by the pressure build up in the ductwork. The truth of the matter is that your HVAC system will use the same amount of energy no matter what. The retort is then, “well if I close off vents in unused rooms, I’ll receive more conditioned air in the rooms I am using.” And the answer is that closing off vents in unused rooms can cause many problems that make it completely not worth it. Your HVAC system was specifically designed for a certain amount of space, vents, and registers. Vents need to be open at all times for everything to run as it should. Closing them messes with the return air duct and causes pressure buildup that will actually cost you more in the long run.

The Use of Fans Will Decrease the Energy Used By the Air Conditioner

A fan’s function is just to circulate the air, not to cool it. The same amount of energy is still needed for the air conditioner to reach the set temperature. Using just a fan will help save energy, but using both will just increase energy use. A ceiling fan cools bodies, not rooms. Of course you feel cooler when a ceiling fan is blowing light air onto your sweaty skin. It’s like a cool outdoor breeze. They both cool your skin due to the effects of windchill. While fans can make you feel around 5 degrees cooler, a ceiling fan will do nothing to keep your space cool while you’re not in it. In fact, the running motor will only add heat to the room.

It Is Not Worth Having Your HVAC Regularly Serviced

This is a big misconception. It’s natural to be skeptical of anyone trying to sell you something, but if HVAC companies really wanted to make more money, they would advise against it. Bi-annual HVAC maintenance prolongs the life of your HVAC equipment and reduces the need for costly repairs. You would not drive your car for miles and miles without changing the oil, rotating the tires or replacing the brake pads. So why would your heating and air conditioning units not need the same attention and service? HVAC units need to be maintained on a regular basis.

These myths go to show that you can’t believe everything you see on the internet. Becoming knowledgeable about what you should and shouldn’t do when it comes to your heating and air conditioning services will help keep the systems running safely and efficiently. Before you decide to try anything new, consider the pros and cons or contact your technician for more advice. When your unit is healthy and efficient, the system is working for your comfort and not against your budget. Early spring is a great time for air conditioning maintenance—right between the high use seasons of winter and summer.
