Busting Myths About AC Maintenance



When it comes to maintaining your air conditioning system, there are several myths and misconceptions that can lead to unnecessary expenses or even damage to your unit. At Gustafson Heating & Air Conditioning, we believe in providing our customers with accurate information to help them make informed decisions. In this blog post, we’ll debunk some common myths about AC service and maintenance.

Myth 1: Bigger is Always Better

Many homeowners believe that bigger air conditioning units will cool their homes more efficiently. However, this is not always the case. An oversized unit may cool your home too quickly, leading to frequent cycling on and off. This results in uneven cooling, increased wear and tear, and higher energy bills. A properly sized unit, based on factors like square footage and insulation, will operate more efficiently and provide consistent comfort.

Myth 2: AC Units Don’t Need Annual Maintenance

  • Skipping annual maintenance can lead to various issues, including:
  • Decreased energy efficiency
  • Reduced cooling capacity
  • Shortened lifespan of the unit

During a professional maintenance visit, our technicians thoroughly inspect, clean, and optimize your system to ensure peak performance and prevent breakdowns.

Myth 3: Closing Vents Saves Energy

Many homeowners believe that closing vents in unused rooms will save energy. However, this practice can disrupt the balance of your HVAC system, causing it to work harder and potentially leading to premature wear and tear. It’s best to keep all vents open and adjust the thermostat to your desired temperature.
