To be Avoided.
Honestly one of the worst companies I’ve ever had the displeasure to deal with - one problem after the other. Allgas are not interested in any issues after a job is completed and take no responsibility for anything they work on that is around, under or over products they have installed. Even though they have to directly connect to it. They are always trying to upsell and will blatantly lie to your face and over the phone as I found out. They have an extremely unprofessional and defensive first point of contact via telephone who will talk over you and not let you explain your issue. She will become aggressive if you push your point and become downright rude. She will also diagnose faults over the phone. Suspect many of their online reviews are fake. To be avoided.
