Reviews
What customers say
Several customers praise courteous, professional technicians and tidy installation work. One customer said an air-conditioning crew arrived on time, provided options and kept the customer updated. The same customer reported that a post-dated cheque for a no-cost, 90-day payment option was processed the next business day, causing an overdraft, and that there was no response after several hours.
