What Every Colorado Homeowner Should Know About Their HVAC System This Season

As winter loosens its grip and spring starts to bloom across Colorado, homeowners breathe a collective sigh of relief. But while you’re packing away snow boots and swapping out flannel sheets, don’t forget—your home’s HVAC system needs a seasonal switch-up, too.

Spring isn’t just about cleaning out closets or refreshing your garden. It’s also the perfect time to get ahead of your home’s comfort and efficiency for the warmer months ahead. And at the top of that list? Air conditioner maintenance.

Why Spring Matters For Your HVAC System

Colorado weather is unpredictable—70 degrees and sunny one day, snow flurries the next. That back-and-forth means your HVAC system works harder than most. A little prep now ensures your AC doesn’t give out on you when the first real heat wave hits.

Here’s what every Colorado homeowner should check this spring:

1. Clear Out Vents and Filters

Your system’s airflow is everything. After a long winter with windows closed tight, filters are likely clogged with dust, pet hair, and pollen. Swap in a fresh filter and check vents to make sure they’re not blocked by furniture or debris. Clean airflow means your AC won’t have to work overtime (which saves you money).

2. Check Your Outdoor Unit

Colorado’s winters can be tough on your outdoor condenser. Ice, snow, leaves, and even nesting critters can all take a toll. Take a walk around your unit and clear at least two feet of space around it. If you spot damage, it’s best to call a pro.

3. Test Your Thermostat

You don’t want to wait until it’s 85 degrees to discover your thermostat is off. Flip on your AC and test a few settings. If things feel uneven or your system kicks on and off constantly, that’s a red flag.

4. Listen for Unusual Noises

Grinding, squeaking, rattling—none of these are normal. Your AC should run smoothly and quietly. Strange sounds can mean loose parts, failing motors, or airflow issues, and it’s best to get them looked at before they turn into costly breakdowns.

5. Seal Leaky Ductwork

Up to 30% of conditioned air can be lost through leaky ducts. That’s energy—and money—out the window. Spring is a great time to inspect your ductwork for gaps, holes, or loose connections, especially in older homes.
