Furnace Maintenance Checklist

Keeping your furnace in top condition is crucial for safe, efficient heating during the colder months. Here’s a step-by-step furnace maintenance checklist to follow before the start of each heating season:

1. Inspect the Thermostat
   Check your thermostat’s settings to ensure it’s set at a comfortable temperature. Make sure the settings are set to “heat” and functioning correctly. Smart thermostats make it easier to program temperature settings for different times of the day, which can save on energy costs.
2. Change or Clean Filters
   Filters should be cleaned or replaced at least every three months, or even more often during peak heating season. Clogged filters can cause your system to work harder, reducing efficiency and indoor air quality.
3. Check Electrical Connections and Wiring
   Over time, wiring can loosen, which can affect the performance of your furnace. Carefully inspect all visible wiring and connections, and look for any signs of wear or loose fittings.
4. Inspect and Clean the Blower Assembly
   The blower is responsible for circulating warm air throughout your home. Dust and debris can accumulate over time, so clean the blower assembly as part of your regular furnace maintenance checklist.
5. Test Safety Controls
   A furnace has safety controls to prevent dangerous operating conditions. Regular testing helps ensure these controls work as intended, keeping your home safe.

How to Maintain Your Air Conditioning Unit

Proper AC maintenance not only keeps your home cool but also extends the life of your air conditioning system. Here’s how to maintain your air conditioning unit:

1. Check the Outdoor Unit
   Make sure the area around the outdoor unit is clear of debris, plants, or any obstructions that could affect airflow. Clear a two-foot space around the unit for proper ventilation.
2. Inspect and Clean Evaporator and Condenser Coils
   Over time, coils collect dirt and dust, reducing their efficiency. Clean the coils annually, as part of your routine AC maintenance, to help your unit cool effectively.
3. Examine and Clean Drain Lines
   Clogged drain lines can lead to water damage and poor system performance. Check the lines regularly and clear any obstructions to prevent water buildup.
4. Change Air Filters Regularly
   As with heating systems, filters are essential to air quality and system efficiency. Change filters every three months to prevent dust and allergens from circulating in your home.
5. Test Thermostat Accuracy
   Ensure your thermostat is accurately reflecting your preferred settings. Faulty thermostats can lead to inconsistent temperatures and higher utility bills.

Routine AC Maintenance for Optimal Performance

Routine AC maintenance ensures your unit runs smoothly during the warmest months. By following these steps, you’ll keep your AC system in peak condition:

1. Inspect Fan Blades and Motor
   Fan blades and the motor should be inspected for any visible wear or damage. Clean the fan blades to remove dust buildup, which can affect airflow and reduce cooling efficiency.
2. Lubricate Moving Parts
   Proper lubrication of moving parts reduces friction, wear, and noise. This is especially important for older systems where components may require extra care.
3. Tighten Loose Connections
   Electrical and mechanical connections can become loose over time. Regularly check connections and secure any loose parts to ensure your system operates reliably.
4. Adjust Refrigerant Levels
   Incorrect refrigerant levels can decrease cooling efficiency. Have a professional check and adjust refrigerant levels as part of your routine maintenance.
5. Check System Controls
   System controls should be tested to confirm that the air conditioner starts, operates, and shuts down properly. This can prevent unexpected breakdowns on hot days.

Residential HVAC Inspection Checklist​

Scheduling a residential HVAC inspection allows you to detect any small issues before they become larger problems. This checklist covers essential areas that need regular attention:

1. Inspect Ductwork for Leaks or Blockages
   Leaks in ductwork can lead to energy loss and reduced indoor air quality. Regular inspection helps prevent energy waste and maintains comfort levels in each room.
2. Evaluate Airflow
   Airflow should be measured and adjusted as needed to ensure even distribution of heating or cooling throughout the home. Inadequate airflow may indicate a need for cleaning or repairs.
3. Check Electrical Wiring and Safety Components
   Inspections should cover all electrical connections and safety components to ensure they’re working as they should. Faulty wiring can be a fire hazard, so these checks are essential for safety.
4. Analyze System Efficiency
   An HVAC technician can help you understand if your system is running at optimal efficiency. This analysis may identify areas for improvement, such as upgrading components.
5. Inspect the Heat Exchanger
   The heat exchanger in a furnace should be inspected for cracks or damage. A damaged heat exchanger can release harmful gases, making this check an essential safety measure.
