Essential DIY Tips for HVAC Maintenance and When to Call the Pros


When it comes to maintaining your home’s heating, ventilation, and air conditioning (HVAC) system, there are some tasks you can tackle yourself and others that require professional expertise. At Holt Plumbing and Heating, we believe in empowering homeowners with knowledge while also emphasizing the importance of professional services for complex issues. This article will provide you with valuable DIY tips and guidance on when to seek professional assistance for your HVAC needs.

DIY HVAC Maintenance Tips

1. Regular Filter Changes

One of the simplest yet most crucial tasks you can perform is changing your HVAC system’s air filter regularly. This helps maintain air quality and system efficiency. Aim to replace your filter every 1-3 months, depending on usage and filter type.

2. Keep the Outdoor Unit Clean

For central air conditioning systems, ensure the outdoor unit remains free from debris. Regularly remove leaves, twigs, and other obstructions from around the unit to maintain proper airflow.

3. Clean Air Vents and Registers

Dust and debris can accumulate in your home’s air vents and registers, reducing airflow and efficiency. Vacuum these areas regularly and wipe them down with a damp cloth to keep them clean.

4. Check and Clean Condensate Drain Lines

Air conditioners produce condensation, which is typically removed via a drain line. Check this line periodically for clogs and clean it using a mixture of water and vinegar to prevent mold growth and water damage.

5. Maintain Proper Thermostat Settings

Program your thermostat for energy efficiency. During summer, set it slightly higher when you’re away or sleeping, and in winter, set it lower during these times.

When to Call the Professionals

While DIY maintenance is important, certain tasks require the expertise of licensed HVAC professionals. Here are situations when you should contact Holt Plumbing and Heating or another reputable HVAC service provider:

  • Annual professional maintenance and inspections
  • Strange noises or odors coming from your HVAC system
  • Inconsistent heating or cooling throughout your home
  • Sudden increases in energy bills

  • Repair of complex components like compressors or motors
  • Refrigerant leaks or recharging

Finding a Licensed HVAC Professional

1. Check for proper licensing and insurance
2. Look for experienced technicians with good reputations
