Hey, it’s April Fool’s Day! However, we are all about keeping it real and not fooling anyone, so let’s dive into debunking HVAC myths and sharing top practices for your HVAC system at Fairfield-Hamilton Heating & Cooling. In the world of HVAC, there’s a ton of misinformation floating around, so let’s separate fact from fiction and steer clear of those HVAC myths this April Fools’ Day!  

1. The “Air Filter” Myth   

If you’ve been around the block with us before, you probably know this already, but ignoring your air filters is a big no-no! Air filters are super important for your HVAC system and should be swapped out every 1-2 months. Forgetting to switch them can cause issues like less airflow, higher bills, and system breakdowns. It’s like skipping an oil change for your car – seems small now, but turns into big trouble later. 

Counter this Myth with Best Practices: Don’t forget to set reminders for changing your air filters on time. Also, it’s not a bad idea to think about getting top-notch air filters to boost indoor air quality and shield your HVAC system and home from dust and debris buildup.   

2. The “raiser/lower the Temperature” Myth 

This myth is a pretty common one. The thinking that turning your thermostat way up (or down) will warm or cool your house faster is believed by many. But most home HVAC systems pump out air at a steady rate, no matter what temp it is set at. So, cranking the thermostat just means wasting energy and getting hit with bigger bills. 

Counter this Myth with Best Practices: For the best method, just dial in your ideal temp on the thermostat and let your system work its magic gradually. Additionally, you should think about getting a smart thermostat if you don’t have one already to tweak temps automatically as per your routine, for that extra ease and saving energy too. 

3. The “Thermostat Placement” Myth 

This one is yet another HVAC myth. Where you put your thermostat really matters for how well your HVAC system works. If it’s too near heat sources like fireplaces, direct sunlight, or even windows and drafts, it can give wrong readings and mess with the temperatures in your home, making it blow out air incorrectly. 

Counter this Myth with Best Practices: Put your thermostat on a central spot inside a wall, away from heat sources or drafts. If needed, you can always chat with your HVAC tech to find the perfect spot for your system and home layout. 

4. The “Preventative Maintenance Isn’t Necessary” Myth 

This one’s totally off-base. It’s not true at all because taking care of your HVAC system with regular maintenance is key for its longevity and efficiency. Routine checks can help avoid surprise breakdowns, boost performance, and prolong the life of your system. Treat it like a checkup for your HVAC; catching problems early can prevent pricey repairs later on. Plus, staying up to date with them will keep your manufacturer’s warranty up to date. 

Counter this Myth with Best Practices: Schedule annual service appointments with a licensed HVAC technician. Usually, aim for one seasonal checkup for your AC in the spring or early summer, and another for your furnace in the fall. These checkups involve cleaning parts, looking for wear and tear, and making sure the system runs efficiently. Taking this proactive approach can save you money in the long run and keep your system prepared for every season.   


While HVAC myths might not seem like a big deal, they could end up costing you a lot and even harm your HVAC system. By knowing the truth and following the best practices in the industry, you can keep your HVAC system running efficiently and comfortably for longer. Don’t be fooled by false information; instead, rely on the expertise of your local NATE-certified technicians from Fairfield-Hamilton Heating & Cooling.
