Your ducted split air conditioning system is a workhorse, keeping your home cool in summer and warm in winter. But like any hard-working appliance, it needs regular care to perform its best. The good news? Many crucial maintenance tasks are simple and can be done by you!

Why Bother with Regular Maintenance?

Consistent upkeep isn't just about avoiding breakdowns; it's about:

• Optimal Performance: Ensuring your system delivers consistent comfort.

• Saving Money: Preventing minor issues from becoming costly repairs and reducing energy bills.

• Extended Lifespan: Protecting your investment for years to come.

• Better Air Quality: Minimizing dust, allergens, and contaminants in your home.

• Safety: Mitigating risks like electrical faults or refrigerant leaks.

Your Key Responsibilities as a Homeowner:

1. Check and Change Your Air Filters (Crucial!):

   • The air filter is your system's first line of defense against dust and debris. A clogged filter restricts airflow, forcing your system to work harder, leading to inefficiencies and higher energy bills.

   • Frequency: At least once a month for heavy dirt environments, every 2-3 months for normal environments. Some filters can be washed, others need replacement.

   • How: Locate your return air grille, remove the old filter (note the airflow arrow!), clean or replace, and reinsert, ensuring the arrow points towards the furnace/blower.

   • Signs of a Clogged Filter: Reduced airflow, higher energy bills, unusual noises, unpleasant odors, or even water leaks.

2. Maintain Your Outdoor Unit (The Condenser):

   • This unit needs clear space to dissipate heat effectively.

   • What to Do: Keep the area around it free of leaves, dirt, dust, and obstructions like shrubs. Regularly sweep or wipe down the unit. You can carefully hose it down (after turning off power at the breaker!) to remove accumulated dust but never use a pressure washer.

   • Bonus Tip: If you notice bent coil fins, a specialized "fin comb" can gently straighten them to improve airflow.

3. Clean Vents and Registers:

   • Dust, pet fur, and other particles can accumulate on your indoor vents and registers, impeding airflow.

   • Action: Regularly vacuum these components. Also, ensure furniture, rugs, or curtains aren't blocking them, which can restrict airflow and create uneven temperatures.

4. DIY Visual Inspection:

   • Periodically check both units for any obvious signs of wear, damage, or leaks (water or potential refrigerant).

   • Listen & Smell: Pay attention to unusual noises (rattling, banging, hissing) or odors (musty, burning). These can be early warnings of problems.

   • Ductwork Check: If accessible, look for visible leaks, tears, or damp spots on your ductwork. Minor leaks can sometimes be temporarily patched with duct tape.

While these owner tasks are vital, remember that professional servicing is also essential, usually twice a year, for a more comprehensive inspection and cleaning. By staying on top of these basic maintenance procedures, you'll ensure your ducted split system runs efficiently, keeps your home comfortable, and lasts for years to come.
