Don't Just Take Our Word For It
FrostLine installed a full ducted system in our 4-bedroom home. The team was professional, clean and finished ahead of schedule. Our energy bills have dropped significantly and the house is perfectly comfortable year-round. Couldn't recommend them more highly!
Had an emergency breakdown on the hottest day of the year. Called FrostLine at 9pm and a technician was at my door by 10:30pm. Fixed it on the spot. Absolutely phenomenal service. I've since moved all our commercial properties to their maintenance plan.
We needed a commercial refrigeration system for our restaurant. FrostLine provided a detailed quote within 24 hours, completed the install over a weekend to minimise disruption, and the system has run flawlessly for 8 months. Fair pricing too.
