Debunking Common Myths About Furnace and HVAC Services


When it comes to furnace maintenance and HVAC services, there are many myths and misconceptions that can lead homeowners astray. At Garrett Plumbing & Heating Co., we believe in providing accurate and reliable information to our customers. In this blog post, we’ll debunk some of the most common myths surrounding furnace service, heater installation, air conditioner service, and AC repair.

Myth #1: Skipping Annual Maintenance is Okay

Many homeowners believe that they can skip annual maintenance on their HVAC systems without any consequences. However, this is a myth that can lead to costly repairs and premature system failure. Regular maintenance is crucial for ensuring the efficiency, safety, and longevity of your furnace, air conditioner, and other HVAC components.

Myth #2: Bigger is Always Better for HVAC Systems

  • When it comes to HVAC systems, bigger is not always better.
  • An oversized system can lead to inefficient operation, increased energy costs, and uneven heating or cooling.
  • A properly sized system, tailored to your home’s needs, will provide optimal comfort and efficiency.

Myth #3: Closing Vents Saves Energy

Another common myth is that closing vents in unused rooms can save energy. However, this practice can actually put additional strain on your HVAC system, leading to decreased efficiency and potential damage. HVAC systems are designed to operate with a balanced airflow, and closing vents disrupts this balance.

Myth #4: DIY Repairs are Easy and Cost-Effective

While some minor HVAC maintenance tasks can be done by homeowners, it’s best to leave complex repairs and installations to professional HVAC technicians. Attempting DIY repairs on complex HVAC systems can lead to further damage, safety hazards, and potentially void warranties. Professional technicians have the knowledge, tools, and expertise to properly diagnose and repair HVAC issues.
