Common Myths About Air Conditioning That Are Costing You Money
When the desert heat of Arizona hits triple digits, your air conditioning system becomes your best friend. However, many homeowners operate their systems based on misconceptions that not only reduce efficiency but also increase energy bills. At Perry Heating, Cooling, and Plumbing, we’ve been helping residents of Tucson and surrounding areas stay comfortable since 1949, and we’ve heard every myth in the book.
Today, we’re debunking some of the most common air conditioning myths that might be costing you money.
Myth #1: Cranking the Thermostat Lower Will Cool Your Home Faster
Many homeowners believe that setting the thermostat to a much lower temperature than desired will cool their home more quickly. This is simply not true. Your air conditioner works at the same speed regardless of the temperature setting. Setting your thermostat to 65°F when you want a 72°F home won’t cool it any faster than setting it directly to 72°F. Instead, it will just make your system work longer until it reaches that unnecessarily low temperature, wasting energy and money.
Myth #2: Closing Vents in Unused Rooms Saves Energy
It seems logical that closing vents in unused rooms would direct more cool air to occupied spaces and save energy. However, modern HVAC systems are designed to balance airflow throughout your entire home. Closing vents creates pressure imbalances that can damage your system over time and actually reduce efficiency.
Myth #3: Bigger Air Conditioners Provide Better Cooling
When it comes to air conditioners, bigger isn’t always better. An oversized unit will cool your home too quickly, shut off before properly dehumidifying the air, and then cycle on again shortly after—a process called “short cycling” that wastes energy and causes unnecessary wear and tear. The professionals at Perry Heating, Cooling, and Plumbing can help you find the perfect size unit for your Oro Valley or Catalina Foothills home.
Myth #4: Maintenance Is Only Necessary When Something Breaks
Many homeowners in Casas Adobes and across Tucson only call for service when their system stops working entirely. This reactive approach often leads to more expensive repairs and premature system failure. Regular maintenance:
- Improves efficiency by up to 30%
- Extends system lifespan
- Prevents costly emergency repairs
- Maintains manufacturer warranties
- Ensures consistent comfort throughout your home
Myth #5: Air Filters Only Need Changing Once a Year
Your air filter plays a crucial role in both system efficiency and indoor air quality. In the dusty desert climate of Arizona, filters can become clogged much faster than you might expect. Most homes should change filters every 1-3 months, depending on factors like pets, allergies, and system usage.
Myth #6: Ceiling Fans Cool Rooms
Ceiling fans don’t actually lower the temperature in a room—they create a wind chill effect that makes people feel cooler. Running fans in empty rooms wastes electricity without any benefit. Use fans strategically when rooms are occupied, and you can set your thermostat a few degrees higher without sacrificing comfort.
