"We had four air conditioners installed and couldn't be more satisfied. From the initial quotation to the final installation, communication was always prompt and professional. The installer arrived on time, worked diligently, and ensured everything was installed to a high standard. Excellent workmanship and very reliable service."

"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."
