As the weather warms up and spring rolls in, it’s the perfect time to give your HVAC system the attention it needs after working hard through the winter. Seasonal maintenance isn’t just about comfort—it’s about keeping your system efficient, extending its lifespan, and avoiding costly breakdowns when you need cool air the most.

At TOBIN HVAC, we know the importance of staying ahead of potential issues. With decades of experience serving Colorado homes and businesses, our mission is to keep your indoor environment comfortable year-round. Here are our top spring HVAC maintenance tips to help you prep for the warmer months ahead.

Replace or Clean Your Air Filters

This is the easiest—and one of the most important—steps you can take. A dirty air filter reduces airflow, forces your system to work harder, and can lead to poor indoor air quality. We recommend checking your filter every month and replacing it at least every 60–90 days.

Tip: If you have pets or allergies, consider replacing your filters more frequently.

Clear Debris Around Outdoor Units

Over the winter, leaves, branches, and debris can accumulate around your outdoor condenser unit. This can restrict airflow and reduce efficiency. Make sure to clear at least two feet of space around the unit and remove any buildup on the fins or grates.

Check Thermostat Settings

Now’s a great time to switch your thermostat from “heat” to “cool” and test your system before you really need it. Make sure the thermostat is reading the correct temperature and responds properly when adjusted.

Bonus: If you haven’t already, consider upgrading to a programmable or smart thermostat to improve energy efficiency and comfort.

Inspect and Clean Vents and Registers

Walk through your home and ensure that all air vents and registers are open and unobstructed. Clean off any dust or buildup that may have formed during the winter. This helps maintain even airflow and balanced temperatures throughout your home.

Check the Drain Line

Your HVAC system includes a condensate drain line that can clog with algae or mold over time. A clogged drain line can lead to water damage or system shutdowns. Flushing it with a small amount of white vinegar can help prevent blockages.

Listen for Unusual Noises

When you first turn your AC on for the season, listen closely. Any buzzing, rattling, or grinding sounds could be signs of a mechanical issue that needs professional attention. Catching these early can prevent major damage down the road.

Schedule a Professional Tune-Up

While DIY checks are helpful, nothing beats a professional spring HVAC inspection. At TOBIN HVAC, our technicians perform a thorough inspection and tune-up that includes:

• Checking refrigerant levels
• Inspecting electrical components
• Lubricating moving parts
• Cleaning coils and condensers
• Verifying system performance and efficiency

Routine maintenance helps avoid surprise breakdowns, ensures your system is operating at peak efficiency, and extends the life of your equipment.
