Debunking 5 Top HVAC Myths

HVAC Contractor Debunks 5 Common HVAC Myths

The HVAC system plays a pivotal role in keeping your home comfortable. It’s also of the most significant monthly expenses that most homeowners have. These factors are key reasons why myths abound about how to use an HVAC system, maintain it, and save money doing it. As a leading Santa Rosa HVAC contractor, Next Level HVAC wants to set the record straight by debunking some common myths about these essential home systems. Here are five of them.


1. Myth: Larger Systems Are Better Systems

Bigger is not always better in HVAC systems. One that is too big for the home may cause you to pay more in the long run with higher utility bills. A too-powerful system will work harder by quickly and frequently turning on and off, over and over again. The results are that you use more electricity and possibly shorten the unit’s lifespan through additional wear. If you are considering a new system, consult an HVAC contractor about the appropriate size for your home.


2. Myth: You Can Install the Thermostat Anywhere

The thermostat “reads” the home’s temperature to determine when to turn the HVAC system on and off. An accurate reading is essential to your comfort, or you may be too warm or too cold. Elements that can affect the reading if your thermostat is located nearby include the following:

  • Drafts from windows and doors
  • Stoves, ovens and other kitchen appliances
  • Vents that blow hot/cold air
  • Direct sunlight


You might think hallways are a good location, but they tend to have a somewhat different flow of air than other places in the home. A good choice is a living room, in a spot that avoids the influences noted above.


3. Myth: Closing Doors and Vents in Unused Rooms Saves Energy

This myth may come from days when a central stove or fireplace was used and it does not take into account that today’s systems work differently. Furnaces are chosen based on the home’s size. By blocking vents or doors, you are altering the airflow, which means the furnace must work harder to deliver air throughout the house.


4. Myth: Filters Can Be Changed Once a Year

Filters work to capture dirt, debris and pollutants and remove them from the air. When it is “full,” it no longer works as well, and neither does the system, which must work harder due to reduced airflow. Air filters should be replaced every two to three months. Those with pets or allergies may choose to replace them more often.


5. Myth: If It’s Not Broke, Don’t Fix It

Your HVAC system works hard all year and, like any machine, should have regular maintenance. This can help prevent a breakdown when you need it most or avoid more costly repairs when a problem is resolved in its early stages. Scheduled maintenance can also ensure your unit remains energy-efficient.
