Common AC Repair Myths That Could Be Costing You Money

At Belyea Brothers, we’ve heard it all when it comes to air conditioning misconceptions. These myths don’t just circulate through neighborhoods—they can actually lead to higher energy bills, unnecessary repairs, and shortened equipment lifespan. Today, we’re setting the record straight on some of the most prevalent air conditioning myths.

Myth #1: Bigger AC Units Provide Better Cooling

Many homeowners believe that purchasing the largest air conditioner they can afford will result in a cooler home. In reality, an oversized unit will short cycle—turning on and off frequently—which wastes energy and doesn’t properly dehumidify your home environment. A properly sized unit, determined by a professional load calculation, will operate efficiently and provide consistent comfort.

Myth #2: Closing Vents in Unused Rooms Saves Energy

This common misconception actually causes more problems than it solves. Modern HVAC systems are designed to distribute air evenly throughout your home. Closing vents increases pressure in your ductwork, potentially causing leaks and forcing your system to work harder. The result? Higher energy bills and potential system damage.

Myth #3: AC Maintenance Is Only Necessary When Something Breaks

Waiting until your system fails before calling for service is like waiting until your car breaks down before changing the oil. Regular maintenance:

• Prevents costly emergency repairs
• Extends equipment lifespan
• Maintains efficiency and lower operating costs
• Preserves manufacturer warranties

Myth #4: The Thermostat Location Doesn’t Matter

Your thermostat’s placement significantly impacts your system’s efficiency. Installing a thermostat near heat sources (sunny windows, appliances, lamps) or in drafty areas causes “ghost readings” that trigger unnecessary cycling. The ideal location is on an interior wall, away from direct sunlight, drafts, doorways, and heat-generating appliances.

Myth #5: Air Filters Only Need Changing Once a Year

This myth leads to reduced airflow, decreased efficiency, poor indoor air quality, and system strain. Most filters should be checked monthly and replaced every 1-3 months, depending on factors like pets, allergies, and system usage. This simple maintenance task can save you significantly on repair costs.

Myth #6: Cranking the Thermostat Lower Cools Your Home Faster

Your air conditioner cools at the same rate regardless of how low you set the thermostat. Setting it extremely low won’t speed up cooling but will waste energy as your system runs longer than necessary. Instead, use a programmable thermostat to maintain consistent, efficient temperatures.

The Truth About AC Efficiency

The key to maximizing your comfort while minimizing costs lies in proper installation, regular maintenance, and understanding how your system actually works.
