Reactive Maintenance

Reactive Maintenance is one of RJ McCulloch's key strengths. With a background in plumbing and heating maintenance, our engineers have a wide knowledge of repairing a variety of installations.

"A lot of guys don't know about repair" says Ross, "they just install. We are experts at repairs as well, and creating the most cost effective and efficient solution for the client in any given situation."

“We fit external controls, actuators and pumps, and can design a system it to suit the individual needs of the client - system resistancy, pump pressures, system head loss are all taken into account. We create a tailor made system design to suit your needs.”

We were creating a new build at the park and Ross advised us what type of green energy heating system would suit us best. So we opted for a biomass boiler, and it's been great. The installation went smoothly - everything went to schedule and was on budget.

Ross put in touch with a consultant who helped us with the detail of the RHI application. All in all we're really happy with the installation and would recommend RJ McCulloch to anyone needing a heating system installed.

I got in touch with RJ McCulloch through a word-of-mouth recommendation. Ross advised me on the best type of heating source for our needs, which are quite unique - a busy bus station. The installation, a new high efficiency gas boiler, was tailored to suit our needs, and carried out within the given timeframe. It had to be done in stages due to our work needs, and this all went as planned.

The new system is much more efficient. Ross set it all up for us so it's timed and heat controlled, and came out to check things were going ok, going through the manual with me so I knew exactly how everything worked. He also does reactive maintenance for the system, so I'm happy in the knowledge that should anything be needed he's just a phonecall away.

I'm really happy with the work Ross did both at my home at my practice. Having a busy dental surgery, things needed to be fitted around that and Ross was very obliging, accommodating our needs and working quickly and efficiently
