Common HVAC Myths That Are Costing You Money


Separating Fact from Fiction in Home Comfort

At Reliable Heating & Cooling, we frequently encounter misconceptions about heating and cooling systems that can lead to higher energy bills and reduced comfort. Today, let’s debunk one of the most persistent myths in our industry.

The Myth: Closing Vents in Unused Rooms Saves Money

Many homeowners in O’Fallon and Saint Peters believe that closing vents in unused rooms will reduce their energy consumption and save money. This widely spread home heating misconception actually does more harm than good.

Here’s why this myth is false:

1. Increased System Pressure
– Closing vents creates additional pressure in your ductwork
– This extra strain can damage your HVAC system
– May lead to air leaks in duct connections

2. Reduced Efficiency
– Modern HVAC systems are designed for whole-house balance
– Blocking airflow disrupts this balance
– Forces your system to work harder

3. Higher Energy Costs
– Additional strain leads to increased energy consumption
– Can result in premature system wear and tear
– May void manufacturer warranties

The Better Approach

Instead of closing vents, consider these energy-saving alternatives:

• Install a programmable thermostat
• Schedule regular maintenance
• Ensure proper insulation
• Use ceiling fans to improve air circulation

Remember, your HVAC system works best when allowed to operate as designed. For optimal performance and efficiency, keep all vents open and unobstructed, even in rarely used rooms.
