I recently had a new air conditioning system installed in my Bristol office by Chiller Technical Solutions Ltd, and the experience was excellent from start to finish. From my initial enquiry through to the final installation, the team were professional, reliable, and a pleasure to deal with. They carefully talked me through the available options and helped me select the ideal system to suit both my space and budget, which I really valued. The installation itself was seamless and well organised, the engineers worked efficiently, kept everything clean and tidy, and clearly had a high level of expertise. What really set them apart was their outstanding customer service. They were always happy to answer questions, followed up after the installation to ensure everything was working perfectly, and even shared helpful maintenance advice. It’s refreshing to work with a company that truly prioritises both quality workmanship and customer care. We are now getting the ball rolling on getting the same units installed at our Plymouth office!

Frequently Asked Questions

Find quick answers to common questions about our HVAC services, emergency support, and technical expertise below.

How do you determine which HVAC system is right for my building?

Every project begins with a comprehensive site survey where we assess your building’s layout, occupancy levels, heat loads, and specific operational needs. This data-driven approach ensures we design a system that is perfectly sized for your space—preventing the inefficiency of under-powered units or the wasted energy of over-sized systems.

Can you design systems for temperature-critical environments?

Yes. We have extensive experience designing solutions for environments where precise temperature control is vital, such as data centres, industrial manufacturing processes, and healthcare facilities. Our designs focus on redundancy and reliability to ensure your critical operations are never compromised.

How long does a typical HVAC installation take?

The timeline varies depending on the scale and complexity of the project, ranging from a few days for split-system installs to several weeks for large-scale industrial chillers. During the design phase, we provide a clear project timeline and work closely with you to schedule the installation at a time that minimizes disruption to your business.

Do you work with specific equipment manufacturers?

As an independent specialist, we are not tied to a single brand. While we have expert-level knowledge of leading manufacturers like Trane, Daikin, Mitsubishi Electric, and Carrier, we select the specific equipment that offers the best performance, energy efficiency, and value for your unique requirements.

Will a new installation help reduce my energy bills?

Absolutely. Modern HVAC systems are significantly more energy-efficient than older models. Our design process prioritizes high-efficiency equipment and smart control solutions, which can lead to a substantial reduction in energy consumption and lower long-term operating costs for your facility.

What happens after the installation is complete?

Once the system is installed, we conduct rigorous commissioning and testing to ensure everything is operating at peak performance. We then provide a full handover, including staff training and documentation. To protect your investment, we also offer tailored maintenance programs to ensure your new system remains efficient for years to come.
