Electrical, Air Conditioning & Refrigeration —
one Gladstone team.
Four trades under one licence, solar included. The same local crew has kept Gladstone homes, businesses and industrial sites powered and cool for almost 30 years — one quote, one team, one point of accountability.
Every trade your building needs, without the juggling act.
Most jobs in Central Queensland touch more than one trade. A new split system needs an electrician and a refrigeration technician. A solar install needs switchboard work. DSMQ holds every relevant licence in-house, so you brief one team and they own the whole job.

Local knowledge you can't subcontract.
Gladstone is a hard environment on equipment. Salt-laden coastal air corrodes condenser coils. Summer humidity pushes undersized systems past their duty cycle. Industrial dust loads filters faster than any manufacturer's service interval assumes. A contractor driving up from Brisbane doesn't design for that. We do, because we've been repairing the consequences of it for decades.

Fixed written quotesItemised before we start. The number you approve is the number you're invoiced — no call-out surcharge appearing at the end.
-
Equipment sized for the coastWe factor in coastal corrosion, humidity load and industrial dust when specifying units, so systems last their design life instead of half of it.

The same faces, every visitA locally owned business with long-standing technicians. You deal with people who remember your building and its history.
Simple, predictable, and no chasing.
The most common complaint about trades in this region isn't price — it's silence. Here's exactly what happens when you contact us.
Call or enquire
Tell us the job. We'll tell you honestly whether it's a same-visit fix or needs a proper site assessment first, and roughly what it will cost.
On-site assessment
We measure, inspect the switchboard, check access and pipe runs, and confirm what the job actually requires — not what's easiest to quote over the phone.
Written fixed quote
An itemised quote covering equipment, labour and compliance work. You'll know exactly what's included and what isn't before you commit.
Installed & certified
Work completed to AS/NZS 3000, site left clean, system commissioned and demonstrated, and your compliance certificate issued.
Trusted by Gladstone homes and businesses.
"Had DSMQ install ducted through the whole house. They picked up that our switchboard needed upgrading first, quoted it up front, and did both in the one go. No second contractor, no second call-out fee."
"Our cool room went down on a Saturday. They had someone out that afternoon and we didn't lose a single tray of stock. We've had them on a maintenance contract ever since."
"Straightforward, on time, and the quote was the quote. After a few bad experiences with other sparkies in town, that's worth a lot."
Covering the Gladstone region and beyond.
We're based in Gladstone and travel throughout the Gladstone Regional Council area, the Banana Shire, the Discovery Coast and up to Rockhampton. If your address isn't listed, call us — chances are we're already working nearby.
Electrical, air conditioning and refrigeration in Gladstone, QLD
Davey Service & Maintenance QLD (DSMQ) is a multi-trade contractor based in Gladstone, Queensland. For almost 30 years we've delivered electrical contracting, air conditioning, solar power and commercial refrigeration across Gladstone, Calliope, Boyne Island, Tannum Sands, Biloela, Agnes Water and Rockhampton — to homes, businesses and industrial sites alike.
One team, or three companies and a month of waiting
What sets us apart in this region is scope. Most local operators specialise in a single trade and subcontract anything adjacent to it. That's how a straightforward split system installation turns into three weeks of coordination: one company to supply the unit, another to run the dedicated circuit, and a third to sign off the compliance.
We hold Electrical Contractor Licence 87731 and ARC trading authorisation AU53529 in-house — the two licences every air conditioning job legally requires.
The same team that quotes your job is the team that finishes and certifies it.
Air conditioning built for Central Queensland conditions
Gladstone's climate punishes undersized and poorly specified air conditioning. Three local factors shorten equipment life here more than almost anywhere else in Australia.
- Humidity loadA system rated purely on floor area runs continuously without ever properly dehumidifying — driving bills up and shortening compressor life.
- Coastal salt airAccelerates corrosion on condenser coils, particularly in Tannum Sands, Boyne Island and Agnes Water where properties sit close to the water.
- Industrial dustGladstone's industrial footprint loads filters and coils faster than manufacturer service intervals assume.
We size systems using room volume, ceiling height, window orientation, insulation and occupancy — not a rule of thumb. For coastal installations we recommend units with treated or coated coils and position outdoor units to minimise salt exposure where the site allows. It costs a little more at installation and routinely adds years to the working life of the equipment.
Full air conditioning servicesLicensed electrical work, residential to industrial
Our electrical division covers everything from a single powerpoint through to full commercial fit-outs and switchboard upgrades. A significant share of the Gladstone housing stock still runs older switchboards with ceramic fuses and no RCD protection on every circuit — a genuine safety issue and, in many cases, the reason an air conditioning or solar installation can't proceed until it's rectified. We identify that at quote stage rather than on installation day.
- Switchboard upgrades and safety switch (RCD) installation
- Fault finding, emergency repairs and after-hours call-outs
- LED lighting upgrades for homes, offices and warehouses
- New circuits, powerpoints, rewires and renovation electrical
- Commercial and industrial maintenance, test and tag, compliance testing
Solar power, installed by the team that handles your switchboard
Central Queensland has some of the best solar resource in the country, and Gladstone's high daytime cooling load makes rooftop solar an unusually good fit — you generate most when you consume most. The catch is that solar quality varies enormously. We size systems around your actual consumption profile and the export limits that apply locally, install quality inverters and panels, and complete all switchboard and metering work ourselves.
Talk to us about solarCommercial refrigeration with response times that matter
For a café, butcher, supermarket or pub, a refrigeration failure isn't an inconvenience — it's thousands of dollars of stock on a countdown. We install and maintain cool rooms, freezer rooms, display cabinets and process refrigeration across the Gladstone region, and we prioritise breakdown call-outs accordingly. Clients on a scheduled preventative maintenance contract get first call, which is exactly why we recommend one for any business where cold storage is critical.

What areas does DSMQ service?
We're based in Gladstone and service the wider Gladstone region including Calliope, Boyne Island, Tannum Sands and Beecher, along with Biloela in the Banana Shire, Agnes Water and Seventeen Seventy on the Discovery Coast, and Rockhampton. If you're unsure whether we cover your address, call 07 4973 8067 and we'll tell you straight away.
Are DSMQ technicians licensed and certified?
Yes. DSMQ holds Queensland Electrical Contractor Licence 87731 and Australian Refrigeration Council trading authorisation AU53529. Our technicians are ARC Tick certified to handle refrigerant, and all electrical work is completed to AS/NZS 3000 wiring standards with a Certificate of Testing and Compliance issued on completion.
Can one team handle electrical and air conditioning on the same job?
Yes, and it's the main reason clients choose us. A split system installation needs a licensed electrician for the dedicated circuit and an ARC certified technician for the refrigerant work. Most companies subcontract one half of that.
We hold both licences in-house, so one team arrives, one team finishes, and you're not waiting on a second trade to become available before the job can be signed off.
How much does it cost to install air conditioning in Gladstone?
A standard back-to-back split system installation typically starts around $700 to $900 in installation labour, with the final figure depending on unit size, pipe run length, whether a new dedicated circuit is required, and mounting height or access difficulty. Ducted systems are quoted individually after an on-site assessment.
We provide a firm written quote before any work begins, so you're never guessing.
Do you offer after-hours and emergency call-outs?
Yes. We take emergency call-outs for urgent electrical faults, power outages and refrigeration breakdowns outside our standard trading hours of 7:00am to 5:00pm Monday to Friday. Commercial refrigeration failures are prioritised because of the stock loss involved.
Do you provide a written quote before starting work?
Every job is quoted in writing and itemised before we begin. The price you approve is the price you're invoiced, unless you ask us to change the scope. There are no hidden call-out surcharges added at the end.
Do you work on residential, commercial and industrial sites?
All three. Our work ranges from a single powerpoint or split system in a Gladstone home, through to switchboard upgrades, cool room installations and scheduled preventative maintenance contracts for local businesses and industrial sites across the region.
