On April Fool’s Day, we aim to clarify HVAC myths and provide best practices for your system. In the realm of the HVAC world, separating fact from fiction is truly vital. Otherwise, you can easily get caught up in false information and incorrect practices. So, without further ado, join your local Eastland Heating & Cooling  experts to uncover truths and bust common myths regarding your HVAC system.    

Myth – Air Filters Don’t Need to BE Changed as OFTEN as Recommended   

False! If you are familiar with our services, you are likely aware that air filters are a crucial part of any HVAC system and require regular replacement, typically every 1-2 months. Thus, neglecting this task can result in various issues such as reduced airflow, higher energy costs, and even system failures. Skipping air filter changes is akin to skipping an oil change for your car – seemingly minor, yet with potential long-term consequences.  

Counter this Myth with Best Practices: Setting reminders for yourself ensures timely air filter changes. Moreover, investing in high-quality air filters can enhance indoor air quality and safeguard your HVAC system against dust and debris buildup.  

Myth – Temperatures Should Be Set Higher or lower to Work Faster 

This myth represents a common misconception: setting your thermostat to a significantly higher temperature won’t heat your house faster. Most residential HVAC systems maintain a consistent air delivery rate, regardless of the temperature setting. Consequently, cranking up the thermostat results in unnecessary cooling and increased energy costs, rather than quicker comfort. 

Challenge this Myth with Best Practices: To achieve optimal efficiency and comfort, adjust your thermostat to your preferred temperature and allow your system time to reach it gradually. Installing a programmable thermostat can automatically regulate temperatures based on your schedule, offering convenience and energy savings. 

Myth – Thermostats Can Be Placed Anywhere You Want   

This HVAC myth is incorrect. The positioning of your thermostat can significantly affect your HVAC system’s accuracy and efficiency. Placing it too near heat sources, direct sunlight, or drafts can lead to inaccurate readings and uneven temperatures in your home, causing it to release air at an improper rate. 

Counter this Myth with Best Practices: To ensure optimal performance, place your thermostat centrally on an interior wall, away from direct heat sources or drafts. For the best placement tailored to your system and home layout, consider consulting your HVAC technician for expert advice. 

Myth – Preventative Maintenance Checks Won’t Make a Difference    

 This last one couldn’t be further from the truth. It’s inaccurate because preventative maintenance is essential for the longevity and efficiency of your HVAC system. Regular maintenance checks can prevent unexpected breakdowns, optimize performance, and even prolong the life of your system. Consider it a health checkup for your HVAC system because catching issues early can spare you from costly repairs later. 

Counter this Myth with Best Practices: To maintain optimal performance, it is recommended to schedule annual service appointments with a licensed HVAC company. Typically, you should plan for one seasonal checkup for your AC in the spring or early summer and one for your furnace in the fall. These checkups will involve cleaning components, inspecting for any wear and tear, and ensuring efficient system operation. This proactive approach can result in significant long-term savings and ensure your system is prepared for each season.


Don’t fall prey to these common misconceptions! While some HVAC myths might appear harmless, they can result in expensive errors and harm to your HVAC system. Understanding the facts and following industry best practices is crucial to ensuring the durability, efficiency, and comfort of your HVAC system.
