Dispelling Common AC Myths for Optimal Cooling


When it comes to air conditioning services, there are several myths that can lead to misconceptions and inefficient cooling. At Murphy’s Air Conditioning, Heating, and Plumbing, we’re dedicated to providing reliable information to ensure your comfort and energy savings. In this blog post, we’ll debunk some common myths about air conditioners.

Myth 1: Bigger is Always Better

Many homeowners believe that installing a larger air conditioning unit will provide better cooling. However, this is not the case. An oversized unit will struggle to remove humidity effectively, leading to uneven cooling and potential moisture issues. Properly sized units not only cool more efficiently but also save energy and reduce operating costs.

Myth 2: Closing Vents Reduces Energy Consumption

  • Closing vents in unused rooms does not save energy; it can actually cause your AC unit to work harder.
  • Air conditioning systems are designed to distribute air evenly throughout the entire space.
  • Closing vents creates an imbalance in the system, which can lead to inefficient operation and potential damage.

Myth 3: Air Conditioners Don’t Need Regular Maintenance

Regular maintenance is essential for ensuring your air conditioning system operates at peak efficiency and extends its lifespan. Neglecting maintenance can lead to air conditioner repair issues, higher energy bills, and premature system failure. Professional technicians at Murphy’s Air Conditioning, Heating, and Plumbing can identify and address any potential problems before they become costly repairs.
