For many homeowners and business owners, regular HVAC maintenance often takes a back seat—until the system breaks down in the middle of an Oklahoma summer or a freezing winter night. A common question we hear is: “Can my HVAC go a full year without service?”

Technically, yes—it can. But the real question is: should it? The answer, for anyone who wants long-lasting performance, lower energy bills, and fewer repairs, is no. Let’s break down why skipping even one annual tune-up can cost you more in the long run.

What Happens When You Skip HVAC Service for a Year?

If you decide to go a year—or longer—without professional maintenance, several problems can begin to build up quietly behind the scenes:

1. Reduced Efficiency

Over time, dust, pollen, and debris accumulate in filters, coils, and ducts. This buildup forces your system to work harder to maintain comfortable temperatures, increasing energy use by up to 15–20%.

2. Higher Energy Bills

When your HVAC system isn’t clean or properly calibrated, it draws more power to deliver the same results. You may not notice it immediately, but those small spikes on your utility bills add up across the year.

3. Increased Risk of Breakdowns

Skipping service often means small issues—like loose electrical connections or low refrigerant levels—go unnoticed until they become major failures. A simple annual inspection could prevent costly emergency repairs.

4. Shortened Equipment Lifespan

Most HVAC systems are built to last 12–15 years, but only with consistent maintenance. Without it, wear and tear accelerate, and major components like the compressor or blower motor may fail prematurely.

5. Declining Indoor Air Quality

A neglected HVAC system can circulate dust, mold spores, and allergens throughout your home or office. Regular service includes filter checks and coil cleaning—key steps for maintaining healthy indoor air.

How Often Should You Service Your HVAC System?

Most manufacturers and HVAC experts recommend two tune-ups per year – one in spring for your cooling system and one in fall for your heating system.

If your system is newer and under warranty, these services are often required to keep that warranty valid. Missing just one annual service could void your coverage and leave you paying out-of-pocket for repairs.

Signs Your HVAC System Is Overdue for Maintenance

Even if you’ve skipped a year, it’s never too late to get back on track. Watch for these red flags that your system needs attention now:

• Uneven heating or cooling across rooms
• Strange noises or vibrations
• Weak airflow from vents
• Unusual odors when the system starts
• Higher-than-normal energy bills
• More frequent cycling on and off

If any of these sound familiar, it’s time to schedule a professional inspection.

Why Annual HVAC Maintenance Is a Smart Investment

Think of maintenance as preventive medicine for your HVAC system. A small yearly investment – typically less than the cost of a single major repair—can save you hundreds in energy costs and unexpected breakdowns.

Regular service also gives you peace of mind knowing your system will run safely and efficiently year-round, no matter what Oklahoma weather throws your way.
