Just like any other home appliance, your HVAC system needs regular upkeep to function at its best. This is especially true when transitioning from one season to another, as the changing weather conditions place different demands on your system.  As winter transitions into spring, Durham Region homeowners should start thinking about preparing their HVAC systems for the warmer months. With rising temperatures and increasing humidity, your heating, ventilation, and air conditioning system will need some fine-tuning to keep your home comfortable, energy-efficient, and free of potential problems.

Fortis Heating & Air Conditioning, a locally owned and operated HVAC company servicing the Durham Region, is committed to providing the educational, informative, and helpful content needed to ensure the finest living conditions for you and your family.

In this blog post, we will present a Spring Tune-Up Checklist, guiding you through a series of steps to prepare your HVAC system for the upcoming summer season.

The Spring Tune-Up Checklist is designed to address these shifting demands, touching on elements such as testing and cleaning your air conditioner, inspecting and sealing ductwork, checking for system leaks, and more. By following this checklist, you’ll ensure that your HVAC system is in peak condition, allowing it to work efficiently, keeping your energy costs down, and providing you with a comfortable home.

1. Test and Clean Your Air Conditioner

The first thing to do before the temperatures start rising is to test and clean your air conditioner unit:

  •  Turn on your air conditioner to ensure it is functioning correctly and identify any unusual noises or performance issues.
  •  Clean or replace your air conditioner’s filter to improve the airflow and efficiency.
  •  Remove any dirt or debris around the outdoor condenser unit and ensure it has adequate room for air circulation.
  •  Inspect the condenser coil for any damage and carefully clean it with a soft brush or, alternatively, call in a professional to perform this task.

If your air conditioning unit is not functioning correctly or requires a more in-depth inspection, be sure to contact a certified HVAC technician like those at Fortis Heating to check the system and address any necessary repairs.

2. Inspect and Seal Your Ductwork

Your ductwork plays an important role in distributing cool air throughout your home, so it’s crucial to inspect and maintain it properly:

  •  Visually inspect your ductwork for any possible leaks, damage, or gaps.
  •  Seal any leaks with mastic sealant or heat-approved tape to improve the efficiency of your air conditioning system.
  •  If necessary, call a professional to clean your ducts and remove any dust, allergens or blockages to ensure smooth airflow.

3. Check Refrigerant Levels and Address Any Leaks

Your air conditioner requires the appropriate level of refrigerant to cool your home effectively:

  •  If you are uncertain how to check refrigerant levels, consult your system’s manual or contact a professional HVAC technician for assistance.
  •  Look for signs of potential leaks, such as oily residues or excessively frosty coils.
  •  If you suspect a leak, refrain from using your air conditioner and call a professional immediately, as addressing refrigerant leaks in a timely manner is crucial for preventing damage to your system and the environment.

4. Perform Routine HVAC System Maintenance

Maintaining your HVAC system regularly results in better performance, energy efficiency, and longevity:

  •  Clean or replace air filters every 1 to 3 months or as specified by your system’s manufacturer.
  •  Check your thermostat to ensure it is calibrated correctly and functioning properly. Consider upgrading to a more energy-efficient smart thermostat if you haven’t already.
  •  Schedule annual HVAC maintenance with a trusted service provider like Fortis Heating to ensure a comprehensive inspection, cleaning, and tune-up.
