Stop Believing These 5 HVAC Myths Today

Your HVAC system is a sophisticated machine with numerous components and connections. Because many people have an incomplete understanding of how it works, there are many misconceptions. We’ll explore some of the myths you should know to keep your system in Quitman, GA, running efficiently.

Myth #1: You Can Place the Thermostat Anywhere

One misconception about the HVAC system is that you can place the thermostat anywhere in the house. But according to the Department of Energy, the location of your thermostat can affect its performance and efficiency. Improper placement will create ‘ghost’ temperature readings, forcing your system to short cycle.

The best places are areas where there are no drafts. It should be near a location that reflects the natural temperature of the room. Therefore, the thermostat must not be behind furniture, where obstructions can limit natural airflow.

Ensure the thermostat isn’t in direct sunlight or under sky walls and windows. Check the manufacturer manual for specific instructions for your model. The device should be in an accessible location for easier programming and maintenance.

Myth #2: The Greater Your Equipment’s Capacity, the Better

An undersized HVAC system will keep running to meet the needs of your home. But despite misconceptions, a larger capacity isn’t necessarily better.

An oversized furnace won’t complete a cycle to avoid overheating. It’ll keep switching on and off since overheating can damage critical components such as the heat exchanger.

The short-term consequence of short cycling is the system doesn’t adequately regulate the temperature in the room. The furnace will take longer to heat the house. As a result, the system’s running costs will increase.

In the long run, short cycling will accelerate the deterioration of components. You’ll notice your system requires more frequent repairs. You can talk to our certified heating repair service technicians about troubleshooting your system.

Myth #3: Closing Off Registers Reduces Energy Consumption

Another mistake homeowners make is believing closing off the vents and registers can reduce energy consumption. Not only will those blockages reduce efficiency, but they can also damage parts of your HVAC system.

Closing the registers will redirect the airflow to other open ducts. It can lead to a pressure imbalance and leaks. The average home loses 20% to 30% of its energy through leaky air ducts.

Another problem with the pressure buildup is it makes your HVAC system work harder to distribute air. It’s worth noting service technicians install the ductwork to precise specifications during installation. Closing the registers will force your equipment to work overtime, compromising your comfort.

Myth #4: You Can Use Duct Tape to Seal Your Ductwork

The standard duct tape cannot withstand the conditions of your home’s ductwork. Temperature fluctuations will make the tape peel and fall off. Its adhesive is too weak to handle the cold and heat in the air ducts.

The best option for leaky ducts is a mastic sealant. It is a viscous substance you can find at your local hardware store. It is messier to apply than tape but more effective and durable.

While you can seal holes around fixtures with mastic, you should leave the primary task to a professional. Professionals have the tools to address leaks in unconditioned spaces effectively.

Myth #5: HVAC System Efficiency is More Important than Insulation

The efficiency of your heating system matters, but so do other factors such as insulation. The building envelope must not allow air to escape. Otherwise, even an efficient HVAC system will have to work hard to regulate temperatures.

If there are issues with the building’s envelope, the HVAC system will deteriorate due to leaks and airflow problems. Eventually, your equipment will become inefficient and incapable of providing adequate comfort. That’s why you must address air leaks and insulation problems as soon as you spot them.

Routine maintenance is the best way to keep your HVAC system efficient. A professional can spot issues during the service. Schedule an appointment with Waller Heating & Air Conditioning to take advantage of our Energy Savings Agreement today.
