Our Services
Routine Air Conditioning Maintenance
"Keep your system running efficiently all year round."
Scheduled HVAC servicing including coil cleans, filter changes, drain flushes, and performance testing. Regular maintenance extends equipment life, improves energy efficiency, and prevents costly breakdowns before they happen.
Overview
Most air conditioning breakdowns are preventable. The number one cause of premature system failure on the Central Coast isn't age — it's neglect. Coastal air carries salt, humidity, and fine particles that clog filters, corrode coils, and block drain lines faster than inland areas.
A properly maintained system runs up to 25% more efficiently, lasts 5–10 years longer, and almost never breaks down at the worst possible moment. Gary provides thorough, documented maintenance services for residential and commercial systems across the Central Coast and Lake Macquarie — with a written service report after every visit.

FAQ
Frequently Asked Questions
We recommend a full service at least once per year, ideally before summer. Coastal properties near the Central Coast shoreline benefit from bi-annual servicing due to salt air exposure. High-use commercial systems should be serviced every 3–6 months.
A standard service includes filter cleaning or replacement, indoor and outdoor coil inspection and clean, drain pan and drain line flush, refrigerant level check, electrical connection inspection, and a full performance test. You receive a written report.
Absolutely. A well-maintained system can last 15–20 years. Neglected systems often fail within 8–10 years and consume significantly more energy in the process.
Yes. Many issues develop silently — a slow refrigerant leak, a partially blocked drain, or corroding coils won't affect performance immediately but will cause a failure eventually. Annual servicing catches these before they become expensive problems.
Absolutely. We service all makes and models regardless of who installed them.
Yes. Commercial clients can arrange scheduled maintenance contracts. Residential clients can also set up annual reminders. Contact Gary to discuss what suits your situation.

"Gary came out to my place on pretty short notice and did a great job on maintenance on our ducted system. He's a friendly polite guy and his offsider was great as well — very reasonable price and tidy work. I'll definitely recommend Lilac HVAC and re-engage them for future work."
