Debunking Common HVAC and Plumbing Myths in Central Virginia

When it comes to HVAC and plumbing systems, there’s a lot of misinformation out there. Many homeowners in Central Virginia rely on outdated advice or misconceptions that can lead to inefficiencies, costly repairs, and even damage to their systems. At Browns Heating Air & Plumbing, we want to set the record straight. Here are some of the most common HVAC and plumbing myths debunked.

HVAC Myths:

Myth #1: Closing Vents in Unused Rooms Saves Energy

Reality: Many homeowners think that closing air vents in rooms they don’t use will save energy. In reality, this can actually increase strain on your HVAC system. Your system is designed to distribute air evenly throughout your home, and closing vents can cause pressure imbalances that make it work harder, leading to higher energy bills and possible system damage.

Tip: Keep all vents open and ensure they’re not blocked by furniture to maintain proper airflow.

Myth #2: You Only Need HVAC Maintenance When Something Breaks

Reality: Waiting until your HVAC system stops working to schedule maintenance is one of the biggest mistakes homeowners make. Regular HVAC tune-ups help prevent costly breakdowns and improve efficiency. Central Virginia’s climate sees hot, humid summers and cold winters, meaning your HVAC system works year-round.

Tip: Schedule biannual maintenance—once in the spring for your air conditioner and once in the fall for your heating system—to keep it running efficiently.

Myth #3: Bigger HVAC Systems Work Better

Reality: Many people assume that a bigger air conditioner or furnace will heat or cool their home more effectively. However, an oversized system will cycle on and off too frequently, leading to inconsistent temperatures, higher humidity, and increased wear and tear.

Tip: The best HVAC system for your home is one that’s properly sized based on your home’s square footage, insulation, and layout. An expert technician can help determine the right fit.

Myth #4: You Can Set Your Thermostat Really Low for Faster Cooling

Reality: Your air conditioner cools at the same rate regardless of how low you set your thermostat. Lowering the temperature drastically won’t cool your home faster—it will just make your AC run longer, wasting energy and increasing your bill.

Tip: Set your thermostat to 78°F in summer and 68°F in winter for the best energy efficiency.

Plumbing Myths:

Myth #5: Flushable Wipes Are Safe for Your Plumbing

Reality: Even though they’re labeled "flushable," most wipes do not break down like toilet paper. Over time, they can clog pipes, cause sewer backups, and damage septic systems.

Tip: Stick to flushing only toilet paper to avoid costly plumbing repairs.

Myth #6: A Leaky Faucet Is No Big Deal

Reality: A dripping faucet might seem like a minor nuisance, but over time, it can waste thousands of gallons of water per year, increasing your water bill and putting unnecessary stress on your plumbing system.

Tip: Fix small leaks as soon as possible to save water and prevent bigger plumbing issues down the road.

Myth #7: Ice Cubes Sharpen Garbage Disposal Blades

Reality: While ice cubes can help clean your garbage disposal, they don’t actually sharpen the blades. Most disposals don’t have sharp blades—they use impellers that grind food into small particles.

Tip: To keep your disposal running efficiently, run cold water while using it and avoid putting grease, coffee grounds, and fibrous foods down the drain.

Myth #8: All Water Heaters Are the Same

Reality: Not all water heaters are created equal. Traditional tank water heaters store hot water and keep it ready for use, while tankless water heaters heat water on demand, saving energy and providing an unlimited hot water supply.

Tip: If your water heater is over 10 years old, consider upgrading to a more energy-efficient model to save money on utility bills.
