Installation pricing depends on system capacity, air-handler configuration, controls, electrical requirements and site access. Maintenance is quoted separately according to the equipment and required visit frequency.
Questions buyers ask
Up to five on the multi-zone units we install, though three to four is the practical limit before capacity at peak load suffers.
With a low-ambient kit, yes. A room that only cools above freezing outside is a common and expensive oversight.
Yes. For anything loud or that opens a ceiling, we agree on timing with your building manager in advance, which can include evenings or weekends when preferred.
Around 25 to 32 dB on low, quieter than a fridge. The outdoor unit is the one to think about near a neighbour.
Yes, all of them. Brand has no bearing on whether we will take the call.
To a drain or a condensate pump, with a pan heater outside so it does not freeze into a block.
Sometimes, for a single zone. We will price both rather than steer you to the easier install.
Emergency service available seven days a week. Our phones are answered every day.
