Ask about HVAC: Why maintenance matters more than you think

By Cotney Consulting Group. 

Learn about what your HVAC does — And the myths that could be costing you.

When it comes to home comfort, your HVAC system is the quiet workhorse behind the scenes — until it's not. Regular maintenance is often seen as optional or unnecessary, but the truth is that skipping it can lead to unexpected breakdowns, higher energy bills and shorter equipment lifespan. In this article, we'll answer two important questions: What does HVAC maintenance do? What common myths may cost you more than you realize? 

What routine HVAC maintenance does 

Routine maintenance is more than just a tune-up. It's a comprehensive health check that protects your system and your investment. Here's what a typical maintenance visit includes and why it matters: 

1 - Improves energy efficiency 

Dust, debris and worn components reduce your system's performance. A clean system runs smoother and requires less energy, lowering your utility bills. 

2 - Extends system lifespan 

Minor issues like dirty coils or loose connections strain the system over time. Routine inspections catch these problems early before they become expensive repairs or cause system failure. 

3 - Reduces emergency breakdowns 

The #1 reason for HVAC emergencies? Lack of maintenance. Preventive care helps avoid inconvenient (often costly) breakdowns during extreme weather. 

4 - Protects indoor air quality 

Your HVAC system circulates air throughout your home. Dirty filters, moldy coils or neglected ducts can push allergens and contaminants into your living space. Maintenance keeps your air clean and safe. 

5 - Keeps your warranty valid 

Most manufacturer warranties require regular professional maintenance. Skipping it might void your coverage, even for parts that should be under warranty. 

HVAC maintenance myths that could cost you 

Now, let's bust a few myths that cause homeowners to delay or skip maintenance and may cost you more in the long run. 

Myth 1: "If it's not broken, don't fix it."
Reality: When you notice something's wrong, it may already be expensive. Maintenance is about preventing problems, not reacting to them. 

Myth 2: "Changing the filter is enough." 
Reality: Replacing the filter is essential — but it's only one part of system upkeep. Maintenance also involves cleaning coils, testing controls, checking refrigerant levels and tightening electrical connections. 

Myth 3: "HVAC systems don't need maintenance every year." 
Reality: Your HVAC system runs for hundreds of hours annually. Just like your car needs oil changes, your heating and cooling systems need annual checkups — at minimum once a year, ideally before each heating or cooling season. 

Myth 4: "Maintenance plans are a waste of money." 
Reality: Service plans often cost less than a single emergency repair call. They also prioritize your appointments and include system inspections, helping you avoid future expenses and hassles. 

Pro tip: A healthy roof needs a healthy HVAC — And vice versa 

Just like regular roof inspections help avoid leaks and water damage, HVAC maintenance enables you to prevent indoor comfort problems, energy waste and big-ticket repairs. And if your system sits in your attic or on your roof, your roofing contractor and HVAC tech should be in sync — especially when replacements or upgrades are involved. 

Bottom line: HVAC maintenance is not a luxury — it's a wise investment in your home's comfort, safety and value. 

If you're unsure when your last maintenance visit was, now is the perfect time to schedule one. Your system — and your wallet — will thank you.
