Maintaining your HVAC (Heating, Ventilation, and Air Conditioning) system is crucial for ensuring it operates efficiently, provides comfort throughout the year, and has a long lifespan. Regular maintenance can prevent costly repairs and improve the air quality in your home. As experts in home maintenance, Brooks Handyman Services offers comprehensive tips to keep your HVAC system in top shape.


Why HVAC Maintenance Is Important

Regular HVAC maintenance offers several benefits:

  • Energy Efficiency: A well-maintained system runs more efficiently, reducing energy consumption and utility bills.

  • Extended Lifespan: Proper care can extend the life of your HVAC system, delaying the need for a costly replacement.

  • Improved Air Quality: Clean filters and ducts improve the air quality in your home, reducing allergens and pollutants.

  • Fewer Breakdowns: Routine checks and maintenance can prevent unexpected system failures.


1. Replace or Clean Air Filters

The Tip: Air filters should be replaced or cleaned every 1-3 months, depending on the type of filter and your household conditions.

How to Do It:

  1. Turn off the system: Ensure the HVAC system is turned off before removing the filter.

  2. Remove the filter: Locate the air filter slot, typically near the return air duct or blower compartment.

  3. Inspect the filter: Check for dirt and debris. If it's reusable, clean it with water and let it dry completely. If it's disposable, replace it with a new one.

  4. Insert the new or cleaned filter: Ensure it's properly secured in the slot.

Why It Matters: Clean filters improve airflow and system efficiency, reducing energy consumption and enhancing air quality.

2. Clean the Condenser Coils

The Tip: The condenser coils, located in the outdoor unit, should be cleaned at least once a year to remove dirt and debris.

How to Do It:

  1. Turn off the power: Ensure the HVAC system is off to prevent accidents.

  2. Remove debris: Clear any leaves, grass, or debris around the unit.

  3. Clean the coils: Use a garden hose to gently spray the coils and remove dirt. Avoid using high-pressure settings that could damage the coils.

Why It Matters: Clean coils enable efficient heat transfer, reducing the workload on your system and preventing overheating.

3. Inspect and Clean the Ductwork

The Tip: Regularly inspect and clean your ductwork to ensure there are no blockages or leaks.

How to Do It:

  1. Check for visible issues: Look for any visible signs of dust, mold, or damage.

  2. Seal leaks: Use mastic sealant or metal tape to seal any leaks in the ducts.

  3. Professional cleaning: Consider hiring a professional to clean the ducts every 3-5 years.

Why It Matters: Clean and sealed ducts improve airflow and efficiency, ensuring your HVAC system delivers optimal performance.

4. Check the Thermostat

The Tip: Ensure your thermostat is functioning correctly and set to the desired temperature.

How to Do It:

  1. Check the settings: Make sure the thermostat is set to the correct mode (heating or cooling) and temperature.

  2. Upgrade if necessary: Consider upgrading to a programmable or smart thermostat for better control and energy savings.

  3. Test the accuracy: Use a separate thermometer to compare the temperature readings.

Why It Matters: A properly functioning thermostat ensures your system runs efficiently and maintains a comfortable indoor temperature.

5. Schedule Professional Inspections

The Tip: Have a professional inspect your HVAC system annually to identify and fix any potential issues.

How to Do It:

  1. Find a reputable technician: Look for a licensed and experienced HVAC technician.

  2. Schedule an appointment: Arrange for an annual inspection, preferably before the peak heating or cooling seasons.

  3. Follow recommendations: Address any issues or recommendations provided by the technician.

Why It Matters: Professional inspections can catch problems early, ensuring your system runs smoothly and efficiently year-round.
