We hear a lot of confusing advice about home comfort. When it comes to your HVAC system, misinformation can cost you time, money, and comfort. At Carroll Mechanical Services, we believe in honest, expert guidance. Let’s debunk the four most common HVAC myths we encounter in Longmont, CO!
Common HVAC Myths You Should Stop Believing
Myth: Bigger HVAC Units are Always Better
Many homeowners mistakenly believe that an oversized HVAC system will cool or heat their home faster and more effectively. In reality, a unit that is too large for your space will cycle on and off rapidly — a process called short cycling. This short cycling is inefficient, increases wear and tear on components, and fails to properly dehumidify the air.
Myth: The Thermostat Fan Should Always Be Set to "On"
While setting your thermostat fan to "On" will provide continuous air circulation, it doesn't offer the most efficient operation. When the fan runs non-stop, it continuously pulls air through the ductwork, which often brings dust and contaminants into your system.
Myth: You Never Need a Tune-Up Until Something Breaks
Waiting for a total breakdown before calling for service is a costly mistake many homeowners make. Skipping annual preventative maintenance is like driving a car without changing the oil — a major problem is inevitable. Regular tune-ups from a certified HVAC contractor like us catch small issues, maintain energy efficiency, and are often required to keep your manufacturer's warranty valid.
Myth: Closing Vents in Unused Rooms Saves Energy
This seems logical, but modern HVAC systems are designed and balanced to push a specific volume of air throughout your entire duct system. Closing multiple vents creates pressure imbalances that force your air handler to work harder than necessary, which can actually increase energy consumption and shorten the life of your unit.
