5 Truths Behind Common HVAC Myths in Hagerstown, MD

March 4, 2021

HVAC costs constitute about half of your total home energy bill. You need to understand the basic facts, and it would help if you understood the common myths and misconceptions about the common HVAC system. Here are five truths behind common HVAC myths in Hagerstown, MD:

Thermostat Myths

Most people think you should keep your thermostat set to certain temperatures throughout the day. This is because it may take a lot of energy to heat a cold room than maintaining the temperatures. If this was true, you wouldn’t need a programmable thermostat to adjust your temperatures throughout the day.

Closing your drapes and blinds at night when it’s cold will help insulate your home. It would be best if you opened your blinds and drapes during the day to let in natural light into your home. Your vents and registers should be clear and free of any obstruction.

You should set the temperature back a couple of degrees throughout the day when you’re asleep or away from your home to help reduce your heating and cooling costs. You should also dress appropriately during summer. This means wearing fewer clothes during summer and more clothes during winter.

Duct Tape Myths

Most people think that duct tape is a good material for sealing air duct leaks. This is a myth since duct tapes tend to peel, and it doesn’t stick well.

You should contact a professional when you’re sealing your air ducts. But if you’re sealing the air ducts yourself, you should use aluminum foil tape or a mastic sealant.

A mastic sealant is the best way to seal air duct leaks. You should check for any exposed connections and clean them off before applying the mastic sealant or aluminum foil.

Change Your Filters Once Per Year

You should change your air filters regularly as most HVAC issues relate to airflow problems. A dirty and clogged air filter reduces the amount of air circulating in your HVAC system.

Your heating and air conditioning systems should allow adequate airflow for them to operate efficiently. Clogged air filters reduce the airflow, resulting in compressor and blower motor failure. Your furnace might also overheat and shut down when there’s no sufficient air flowing through it.

A Bigger Air Conditioner is Better

A larger and bigger HVAC system doesn’t mean better comfort or savings. You should ensure that your HVAC system is properly sized when you’re replacing or purchasing a cooling or heating system. An oversized unit may heat your home well, but it might have frequent cycling off and on, creating high humidity conditions inside your home.

An undersized HVAC unit may have more extended cycling, which might end up increasing your energy consumption at home. You should contact an HVAC technician to assist you in analyzing your current system, which includes insulation levels, ductwork and any other factor that may contribute to choosing a properly sized system. Replacing an existing HVAC system with a similarly sized system may lead to voided warranties, high utility bills and other problems.

A well-sized HVAC system will run better and longer than a large system. It’ll increase energy efficiency and help remove uncomfortable moisture in your home.

Routine Maintenance is Optional and Easy to Do

This is false because proper inspection and maintenance of your system are important to its safety and operation. Ensure that your electrical components, fuel, refrigerants and other moving parts are regularly inspected.
