DIY HVAC Maintenance Tips: What You Can Do and When to Call a Pro

Back to Blog

Maintaining your HVAC system is essential to ensure it runs efficiently and effectively year-round. While some tasks can be tackled by homeowners, others require the expertise of skilled HVAC contractors. In this blog, we’ll cover simple DIY HVAC maintenance tips and when it’s time to search for HVAC contractors near you for professional help.

Why HVAC Maintenance Matters

Regular HVAC maintenance isn’t just about keeping your home comfortable—it can also save you money on energy bills, extend the lifespan of your system, and reduce the likelihood of costly repairs. Neglecting your HVAC system can lead to decreased efficiency, higher energy costs, and even complete system failure.

DIY HVAC Maintenance Tips

While there are some tasks best left to professionals, there are several things you can do yourself to keep your HVAC system running smoothly. Here are the top tips:

1. Replace Air Filters Regularly

  • Air filters play a crucial role in maintaining air quality and ensuring your HVAC system operates efficiently. Clogged filters restrict airflow, forcing your system to work harder, which can increase energy bills and wear and tear on the system.
  • Frequency: Replace air filters every 1-3 months, depending on the type of filter and whether you have pets or allergies.
  • DIY Steps:
    • Locate your HVAC filter.
    • Turn off the system before removing the old filter.
    • Insert a new filter, ensuring it’s installed in the correct direction (check the arrows on the filter frame).

2. Clean Around Outdoor Units

Your outdoor HVAC unit (condenser) can become obstructed by leaves, dirt, and debris, reducing its efficiency.

Trim back vegetation within two feet of the unit to allow proper airflow.

DIY Steps:

  • Turn off the power to the unit.
  • Use a garden hose to gently wash away dirt and debris from the fins.
  • Trim back vegetation within two feet of the unit to allow proper airflow.

3. Inspect and Clean Air Vents

Blocked air vents can prevent proper airflow and strain your HVAC system.

DIY Steps:

  • Walk through your home and ensure all air vents and registers are open and unobstructed by furniture or rugs.
  • Use a vacuum attachment to clean dust and debris from the vents.

4. Check the Thermostat

A properly functioning thermostat is key to maintaining a comfortable home and ensuring your HVAC system runs efficiently.

DIY Steps:

  • Replace the batteries in your thermostat regularly (typically once a year).
  • Consider upgrading to a programmable or smart thermostat to save on energy costs.

5. Inspect and Replace Weather Stripping

Gaps around windows and doors can cause your HVAC system to work harder to maintain the desired temperature.

DIY Steps:

  • Inspect weather stripping and seals around doors and windows.
  • Replace any worn or damaged weather stripping to prevent air leaks.

6. Clear Condensate Drain Lines

Over time, condensate drain lines can become clogged, leading to water damage or mold growth.

DIY Steps:

  • Locate the drain line, usually near the indoor unit.
  • Use a wet/dry vacuum or a long brush to clear clogs and ensure proper drainage.

7. Monitor Energy Bills

A sudden spike in energy bills could indicate an issue with your HVAC system.

DIY Steps:

  • Compare your current energy bills to past months.
  • If you notice a significant increase, inspect your system for obvious issues, such as clogged filters or blocked vents.

When to Call a Professional

While DIY maintenance is a great way to keep your HVAC system running smoothly, certain tasks require the expertise of an HVAC professional. Here are some scenarios where it’s best to search for HVAC contractors near you:

1. Annual HVAC Tune-Up

Even if you’re diligent about maintenance, scheduling an annual professional inspection is crucial.

What Professionals Do:

  • Check refrigerant levels.
  • Inspect and tighten electrical connections.
  • Lubricate moving parts.
  • Test system controls to ensure safe and efficient operation.

2. Strange Noises or Smells

Unusual noises, such as banging, grinding, or squealing, or strange smells coming from your HVAC system could indicate serious issues.

Potential Problems:

  • Loose or broken components.
  • Mold or mildew in the ductwork.
  • Electrical issues.

3. Uneven Heating or Cooling

If some rooms in your home are significantly hotter or colder than others, your system may need professional balancing or ductwork repair. Letting these issues snowball or trying to fix it yourself usually does more harm than good.

4. Frequent System Cycling

If your HVAC system is turning on and off frequently (short cycling), it may be due to:

  • A malfunctioning thermostat.
  • Refrigerant issues.
  • A system that’s too large or small for your home.

5. High Energy Bills Despite Maintenance

If your energy bills remain high even after performing routine maintenance, a professional can inspect for underlying issues.

6. Water Leaks or Excessive Moisture

Water pooling around your indoor or outdoor unit often indicates a blocked drain line, refrigerant leaks, or a more serious problem that needs professional attention.

7. Old or Inefficient System

If your HVAC system is more than 10 years old, it may be time to consider an upgrade. Modern systems are far more energy-efficient and can save you money in the long run.

Choosing the Right HVAC Contractor

When it’s time to call a pro, choosing the right contractor is essential to ensure quality work and peace of mind. Here are some tips for finding reliable HVAC repair services:

1. Read Reviews:

Check online reviews and testimonials to find highly-rated contractors in your area.

2. Verify Credentials:

Check online reviews and testimonials to find highly-rated contractors in your area.

3. Ask About Warranties:

Reputable contractors often provide warranties on their work and the parts they install.

4. Check Experience:

Look for contractors with experience servicing your specific type and brand of HVAC system.

Conclusion

Taking care of your HVAC system doesn’t have to be complicated. By following these DIY HVAC maintenance tips, you can improve efficiency, save money, and extend the life of your system. However, when issues arise that require professional attention, don’t hesitate to call skilled HVAC contractors.
