No home or office can bear the Tennessee heat without a functioning HVAC system. At Childs Heating & Air, we’ve heard numerous myths surrounding heating and cooling systems that simply do not hold up upon closer examination. So we’ve put together this guide, to debunk some of the most common HVAC myths.

Myth #1: You only need to change your filter once a year

Despite popular belief, changing your AC filter annually can cause significant damage to your system. On average, we recommend you swap your filter every 30-90 days, depending on the type of filter you have, to ensure your HVAC operates at maximum efficiency.

Another widespread myth is that HVAC system maintenance is unnecessary. This couldn’t be further from the truth. Just like any mechanical equipment, general wear and tear over time can lead to decreased performance and failures if it is not properly maintained.

Myth #2: Maintenance is Unnecessary

Regular maintenance with professionals like those at Childs Heating & Air ensures that your HVAC system runs smoothly, extends the lifespan of your HVAC components, and can even help to lower your energy bills by improving efficiency.

Also, the belief that bigger HVAC units offer better service is another myth often propagated. This is not the case at all. A bigger unit does not equal better cooling and heating. In fact, it’s the opposite!

Myth #3: Bigger HVAC units are better

An oversized HVAC system will cycle on and off frequently, leading to energy inefficiency and increased wear and tear on the system. It’s essential to have a professional evaluate your space to determine the perfect size unit for your needs.

In conclusion, myths, while sometimes rooted in truth, can often lead homeowners to make costly mistakes with their HVAC systems. Truths of the matter are usually more nuanced and requires the expertise of professional HVAC service providers. When in doubt, reach out to us at Childs Heating & Air.
