Here are answers to some of the most common questions we’re asked about commercial HVAC breakdown call outs and emergency situations.
No. We provide business-hours breakdown call-outs for commercial customers without a maintenance contract. Maintenance contracts are only required for priority response, out-of-hours or 24/7 cover.
Our non-contract breakdown service operates during standard business hours Mon-Friday 8am-5pm. Out-of-hours, weekend and 24/7 emergency cover is reserved for customers with a maintenance contract in place.
We attend breakdowns across commercial HVAC, plumbing and drainage systems, including heating failures, air conditioning issues, leaks, blockages, and system faults.
Where possible, yes. Our engineers aim to diagnose and repair faults during the initial visit. If specialist parts or further works are required, we’ll clearly explain the issue and the next steps.
Breakdown call-outs for non-contract customers are charged at standard non-contract rates, which includes a call out fee and then a cost per hour on site (charged in 30 minute periods) plus parts & costs. We’ll always explain costs clearly before proceeding with remedial work.
