✅ Free Guide: Top 5 HVAC Mistakes That Cost You Money (and How to Avoid Them)

You’re the one keeping your home running. We’re just here to help you do it smarter.

Louisiana summers can take a toll. When your air conditioner is working overtime and your energy bills keep climbing, it’s easy to feel overwhelmed. The truth is, many of the most expensive HVAC issues start with small habits that seem harmless.

At Southern Chill A/C & Heating, we’ve seen it all. And we’ve put together this quick guide to help you avoid five of the most common mistakes that can lead to big repair costs and shortened system life.

Let’s get into it.

Mistake 1:Forgetting to Change Your Filter

Why it matters

A dirty or missing air filter forces your system to work harder. This leads to higher energy bills, reduced airflow, and long-term damage to your coils.

How to fix it

Check and replace your filter every 30 to 60 days. You can set a reminder in your phone or let our team take care of it during routine maintenance.

Mistake 2: Closing Vents in Unused Rooms

Why it matters

It might seem smart to close off vents in rooms no one is using. But doing that throws off your system’s balance, increases pressure in the ducts, and causes your A/C to work less efficiently.

How to fix it

Leave vents open throughout the house. If you’re concerned about cooling unused spaces, ask us about proper zoning or duct modifications.

Mistake 3: Ignoring Strange Noises or Long Run Times

Why it matters

Odd sounds and nonstop operation are usually early warning signs. What starts as a loose part or airflow issue can quickly turn into a serious breakdown if left unchecked.

How to fix it

Don’t ignore the signs. Call us if you notice anything unusual. Fixing a minor issue early is always cheaper than dealing with a full system failure later.

Mistake 4: Setting the Thermostat Too Low

Why it matters

Lowering your thermostat to 65 degrees won’t cool your home faster. It just makes your unit run longer and harder, which drives up energy costs and wears out components.

How to fix it

Keep your thermostat set between 72 and 74 degrees and use ceiling fans to circulate air. This helps maintain comfort without overloading your system.

Mistake 5: Skipping Seasonal Maintenance

Why it matters

Without regular checkups, your system can lose efficiency and break down sooner than expected. Small issues that go unnoticed can turn into costly repairs when you need your A/C the most.

How to fix it

Book a tune-up before the heat hits. Our technicians will clean, inspect, and adjust your system to make sure it’s running safely and efficiently all season long.
