Ducted Gas Heating Repairs Canberra

If your gas heater is no longer functioning at its optimal level or has completely stopped, it’s most likely not worth repairing in Canberra now. With the territory transitioning away from gas completely, now is the time to transition from ducted gas to reverse cycle electric heating and cooling.

We hired the team at Alexander Watson to install ceiling insulation, wall insulation, ducted AC and an electrical switchboard upgrade in our 1960s house with some unique challenges. The process of working with the initial inspection and booking in the various stages of the install was really easy and the team was great at communicating different issues and decisions that needed to be made along the way.

We could feel the difference in temperature the day after the ceiling insulation went in and it does such a good job keeping the house cooler on hot days. We look forward to the house being much easier to keep warm when winter rolls around too. The ducted AC unit that was recommended to us works really well, is very quiet and the controller is easy to use or can be controlled with an app.

Would definitely recommend Alexander Watson, they know their stuff.

A few months ago, I asked Alexander Watson to insulate my home - ceiling, wall and underfloor. They were meticulous, and included everything that was needed in the quote - the probability that I needed a new switchboard to comply with updated regulations, making sure the wiring was compatible with insulation - everything. When some work wasn’t needed, they reduced the amount I had to pay to match the work that was actually done. They booked everything so the work was done as quickly as possible. They kept me informed throughout the installation so I knew exactly when they were coming and what was being done. They took before and after photos of every step, to ensure they were keeping to their standards. I was impressed by their safety protocols. I was also impressed that when they came to inspect the work once it was complete, they realised that something hadn’t been done, and quickly ensured that was done too. We were amazed at how much warmer the house was, even though it was after the end of winter, and we hadn’t expected to notice any difference. We’re even more impressed now it’s summer and we’ve had heat waves. I really didn’t expect so much difference since the house is an older brick veneer house, and we haven’t fixed any ventilation issues.

We had ceiling, walls and underfloor retrofitted after vacuuming out decades old debris.
Insulation is excellent but the service and staff are what you pay for, they're all super friendly and helpful.
Insulation went smoothly over 2 days, you get what you pay for, premium service and super nice staff.
4 months post install we had an issue with a leak from the condensation pipe of our aircon in the roof, hadn't turned it on since insulation was installed so wasn't aware.
Wally from AWI came out 2 days later and fixed it on the spot.
Always a warm reception when calling, after instal service is amazing. Can't recommend enough.

Had recent work done to install insulation/electrical and air con replacement, very happy with the work. When they came round to quote it was highly informative and answered every query I had. Punctual and professional every step of the way and I swear my dog would've gone home with every one of them if I hadn't held her back. Highly recommend.

Rarely do you get lucky enough to have work done on your home in such a effortless manner with a superb final product done by polite, professional and knowledgeable trades folk that turn up when they said they would and do the job in the way they said they would. To do all the work at our place in Gowrie we had people putting up scaffold, people doing the roof insulation, people doing the electrical work, people putting sealer on the bricks, people under the house spraying insulation, at one point we think we had 12 trades folk here. They cleaned up after themselves when finished. Best of all the product has already proved its worth. I could not speak higher of the Alexander Watson team, all of them the product they sell and the advice they give. The photos show under the floor and the sealer on the bricks. I’m no longer allowed up a ladder so I can’t show the ceiling work.

Having earthwool insulation installed exceeded my expectations. The multidisciplinary team were fantastic. The house is warmer and no doubt will be cooler in summer. Thoroughly recommended.

Contracted Alexander Watson to remove old insulation batts and remove loose fill from the ceiling.
To be honest, the experience was not a great one.
First point to raise is the constant email replies from different admin stuff. After correspondence with one team member, the following reply would be from a different team member. I found this frustrating. And then that new team member has not read the previous email (this would also be in a working day time frame).
Now the point to raise is of quality of work, they had only cleaned approx 80% of the ceiling, they spent 2 days (a Thursday and Friday). I know this because I cleaned the remaining missed areas including removing old batts on my Saturday so I could lay the insulation properly myself. If I hadn’t of laid the insulation myself and Alexander Watson returned to re-install, then I feel the missed areas would still remain and they would just install over the top. Additionally approx 6 tiles were broken, and they were only siliconed back together.
Now after email correspondence, and I assume with the manager, being told as a customer I should of raised my concerns on the Saturday so this company can return to do a quality check, I feel this should of been done at the workers level before they would of left the job site, then possibly another senior team member should of visited the job site post completion to confirm the work is done. This process has failed from the lowest part of the team. I’ll attach photos to this review.
Now we have both come to an agreement to a reduction in the invoiced amount.

How do I choose ceiling insulation?Dev PPC2025-08-06T04:54:41+00:00

How do I choose ceiling insulation?

It all depends on the type of roof and the ceiling cavity. Usually batts are the best option, however in some cases a loose insulation or other specialised product might be a more effective solution.

How big are the drill holes and how are they filled in?insulation2024-05-13T03:00:42+00:00

How big are the drill holes and how are they filled in?

When the installers are doing wall insulation they will drill small holes under the windows to ensure all parts of the wall is being insulated. The drill holes are 16mm in diameter and are drilled in between the bricks. To fill them in we use mortar. If your mortar is not a standard grey, our team will aim to get the colour as close as possible to leave a seamless finish.

Can electrical work be done after wall insulation?Dev PPC2024-05-13T01:53:26+00:00

Can electrical work be done after wall insulation?

Installing cavity wall insulation can make electrical work more challenging. We recommend completing any wiring or electrical work before installing cavity wall insulation. Insulation doesn’t block access entirely, electricians can add wiring in at a later stage using a fibreglass straw rod, though it’s more complex than in an empty cavity. However, any insulation related electrical compliance work will need to be completed before the wall insulation is installed.
