Cold Change Air Conditioning & Electrical
Customers regularly report quotes hundreds to thousands of dollars below competitors — with same-week availability to match.
David Mills holds both air conditioning and electrical licences, which means jobs combining both trades — a common scenario in renovations and rental upgrades — don't require a second contractor or a second booking window. The technician team (Declan, Lachlan, Braiden, and Noah are each named in reviews) draws specific praise for checking adjacent units proactively, cleaning up without being asked, and explaining what was done — details that matter when you're not on-site to supervise. When booking, it's worth confirming availability directly given the demand, and asking whether your job suits hourly or fixed pricing so there are no surprises on the invoice.

About Cold Change Air Conditioning & Electrical
David Mills leads this team, which splits its work across air conditioning installation and repair, and licensed electrical — a dual-trade setup that lets them handle a full home upgrade in a single visit rather than coordinating two separate contractors. Rebecca manages the office side, and reviewers specifically credit her for responsive communication and making the booking process smooth; David and technicians including Declan, Lachlan (Lochy), Braiden, and Noah handle installs, fault diagnosis, and electrical work on the ground. Declan and Lachlan are each mentioned by name for diagnosing aircon faults quickly and checking neighbouring units proactively while on-site — that kind of unprompted thoroughness is a pattern rather than a one-off. The team runs heavily toward residential work: split system installs in houses and rental properties, hydro-cleaning of existing units, fan and light fitting changes, switchboard upgrades, and generator points — with several property managers and landlords appearing in reviews who use them across multiple dwellings. Speed is a consistent differentiator: multiple reviewers contrast their two-day turnaround against two-week waits from competitors, and same-day installation of replacement units after breakdown comes up more than once. Pricing draws repeated comment — one customer saved $1,000 against a competitor quote, and hourly-rate billing is noted as a fairer structure than fixed quotes that come in at double the market.
Best for: landlords needing fast multi-property aircon installs, homeowners wanting a single team for combined aircon and electrical jobs, and households facing urgent unit breakdowns who can't wait weeks for a competitor.

How quickly can Cold Change Air Conditioning & Electrical get to a job?+
Turnaround is one of the most commented-on aspects of the business. Multiple reviewers were booked within two days when other companies quoted two-week waits, and same-day installation of replacement units after a breakdown is mentioned more than once. That said, availability will vary with demand, so it's worth calling directly to confirm current lead times rather than assuming the same window applies year-round.
What electrical work does Cold Change handle beyond air conditioning?+
David Mills holds electrical as well as air conditioning licences, and the team regularly handles ceiling fan installation, light fitting replacement, power point additions and relocations, switchboard upgrades, generator point installation, and power surge switch fitting. Several reviewers had combination jobs done in a single visit — for example, aircon installs alongside fan and lighting work during a renovation — which avoids the need to coordinate separate trades. If your job crosses both trades, confirm the scope when you request a quote.
How does Cold Change's pricing compare to other local companies?+
Pricing comes up frequently in reviews, and the feedback is consistently positive. One customer reported saving $1,000 against a competitor quote for the same install; another noted they were charged roughly half what other companies quoted. The team uses hourly billing for some jobs, which reviewers describe as fairer than fixed quotes from elsewhere. As with any tradie, get your quote in writing before work starts so you know whether you're on hourly or fixed.
Is Cold Change suitable for rental properties and landlords?+
Several property managers and landlords appear in the reviews and use the team across multiple dwellings — one reviewer has had nine aircons installed over two years alongside fans, lights, and power points across different properties. The team liaises with tenants directly before attending site, which reduces the coordination burden on landlords who aren't local. Rebecca in the office is specifically credited for clear communication and scheduling, which matters when you're managing access for a property you don't live in.
Does the team clean up after installation or service work?+
Cleanup is a recurring detail in reviews — customers mention dust protection during installs, removal of all packaging and offcuts, and leaving the site tidy afterwards. One reviewer specifically noted the team left their home cleaner than it was before they arrived. This comes up across both aircon installs and electrical work, so it appears to be a team-wide standard rather than tied to one individual.
