Essential DIY Tips for Maintaining Your HVAC System Year-Round


At D & K Heating & Cooling, we understand the importance of a well-functioning HVAC system. While professional maintenance is crucial, there are several DIY tasks homeowners can perform to keep their systems running efficiently. Whether you’re in Omaha, La Vista, or Papillion, NE, these tips will help you maintain your heating and cooling systems throughout the year.

Regular Filter Changes

One of the simplest yet most effective DIY maintenance tasks is changing your air filters regularly. This should be done every 1-3 months, depending on factors such as:

  • Pet ownership
  • Allergies in the household
  • Frequency of system use

Clean filters improve air quality and help your system run more efficiently, potentially lowering energy bills.

Keep Your Outdoor Unit Clean

For those with central air conditioning, maintaining the outdoor unit is crucial. Follow these steps:

  1. Turn off the power to the unit
  2. Remove debris like leaves and twigs
  3. Gently clean the fins with a soft brush
  4. Trim any vegetation within two feet of the unit

This simple maintenance can significantly improve your AC’s performance and longevity.

Check and Clean Vents

Regularly inspect and clean your vents to ensure proper airflow. Remove any obstructions and use a vacuum to clear dust and debris. This not only improves air quality but also helps your system work more efficiently.

Programmable Thermostat Usage

If you haven’t already, consider installing a programmable thermostat. This allows you to set different temperatures for different times of the day, optimizing comfort and energy efficiency. Many modern thermostats can be controlled via smartphone apps, making it even easier to manage your home’s climate.

Inspect Insulation

Proper insulation is key to maintaining a comfortable home temperature. Check your attic and wall insulation, and consider adding more if necessary. This can significantly reduce the workload on your HVAC system, especially during extreme weather conditions in Nebraska.

Monitor Humidity Levels

Maintaining proper humidity levels is crucial for comfort and system efficiency. In summer, use dehumidifiers to reduce moisture, and in winter, consider humidifiers to add moisture to the air. This can help your HVAC system work more effectively and improve overall air quality.

Listen for Unusual Noises

Familiarize yourself with the normal sounds of your HVAC system. If you hear any unusual noises like banging, whistling, or grinding, it may indicate a problem. While you shouldn’t attempt to repair these issues yourself, early detection can prevent more serious damage.

Schedule Professional Maintenance

While these DIY tips are valuable, they don’t replace professional maintenance. Schedule bi-annual check-ups with D & K Heating & Cooling to ensure your system is running at peak performance. Our expert technicians can catch and address potential issues before they become major problems.
