When it comes to heating and cooling, there’s no shortage of advice out there. But not all of it is accurate, and believing common HVAC myths could cost you more than you think. At A&R Mechanical, we’ve heard it all from Amarillo homeowners, and we’re here to set the record straight.
Whether you’re trying to save energy on air conditioning in summer or thinking about upgrading to an energy-efficient heater, understanding the facts can help you make smarter choices and avoid unnecessary repairs or high utility bills.
Myth #1: Cranking the Thermostat Heats or Cools Your Home Faster
The Truth:
Your HVAC system delivers air at a consistent rate. Setting the thermostat to 85°F won’t make your heater warm your home faster, it just makes it run longer, which uses more energy and increases wear on your system.
What to Do Instead:
Use a programmable thermostat and set realistic, consistent temperatures. Gradual adjustments help your system work more efficiently and keep your home comfortable.
Myth #2: Closing Vents in Unused Rooms Saves Energy
The Truth:
It seems logical to shut vents in unused rooms, but doing so can actually throw off your HVAC system’s balance. It increases static pressure in the ducts, which can strain your blower and reduce overall system efficiency.
Better Strategy:
Keep vents open to allow for proper airflow. If temperature control in certain rooms is a concern, consider a zoning system or dampers instead.
Myth #3: Your HVAC System Doesn’t Affect Indoor Air Quality
The Truth:
Your heating and cooling system plays a major role in indoor air quality. Dirty filters, neglected ductwork, and poor ventilation can spread dust, allergens, and pollutants throughout your home.
Quick Fixes:
- Change your air filters regularly (every 1–3 months).
- Schedule seasonal HVAC maintenance.
- Ask about whole home air purifiers or humidifier add-ons to improve air quality and comfort.
Myth #4: You Only Need Carbon Monoxide Detectors with Gas Furnaces
The Truth:
While gas furnaces are the most common source of carbon monoxide in homes, other appliances, like water heaters, fireplaces, and stoves, can also pose risks. Carbon monoxide is odorless and invisible, making it especially dangerous.
Why It Matters:
Carbon monoxide detectors should be installed on every level of your home, especially near sleeping areas. They’re inexpensive, easy to install, and could save your life.
Myth #5: You Don’t Need to Replace Your Air Filter If It Still Looks Clean
The Truth:
Even if your air filter looks clean, it can still be clogged with microscopic dust and particles. A filter that’s too full reduces airflow and forces your HVAC system to work harder.
What to Do Instead:
Stick to a regular replacement schedule based on your usage and the type of filter. Changing it at least every 3 months is ideal, and in dusty towns like Amarillo, you may need to change it every 30 days.
Bonus Tip: How to Save Energy on Air Conditioning in Summer
In Amarillo’s intense heat, running your AC nonstop can be a huge expense. Here are smarter ways to stay cool:
- Use ceiling fans to circulate air.
- Keep blinds and curtains closed during the hottest parts of the day.
- Set your thermostat to 78°F when you’re home and higher when you’re away.
- Schedule regular HVAC maintenance to keep your system efficient.
Learning how to save energy on air conditioning in summer can lower your utility bills without sacrificing comfort.
