Heating, Cooling, Ventilation Service & Maintenance

HVAC Service & Maintenance in London, Surrey, Kent, Sussex, Berks, Bucks, inner M25 and Hants.


Service relates to the one off repair of faults or breakdowns you may experience with any heating, cooling, ventilation or HVAC building services systems you have. Comfort has fully trained qualified technicians who you can call out to attend your premises to effect a repair or diagnosis of an ongoing problem or fault.

If the fault can be fixed easily and within your agreed cost and time scale it will be completed for you. We operate a fixed fee call out charge for the first hour and any additional time or work will be advised to you. Parts and consumables will be charged at extra cost if required or necessary.

If the fault requires major work or expensive parts you will be quoted a fixed price to effect the repair before work proceeds.

Service is different to maintenance, but maintenance contract customers are provided with a 365 day, 24 hour call out service for service call outs. It is one of the benefits of having a maintenance contract agreement with Comfort.


Building services systems are complex and require regular planned and preventative maintenance, not only to ensure trouble free operation but also for health and safety reasons.

Because of this requirement, Comfort offers a range of maintenance programme agreements, all tailored to suit your particular requirements.

Planned Visits – Agreements cover any required arrangement where our technicians visit your site at regular planned dates to carry out cleaning, inspection and safety checks.

Manned Sites – Our technicians are based and operate from your premises, managing and carrying out maintenance to an agreed format.

FAQ – My system has a 3-year warranty, I don’t need maintenance until the warranty expires?

Answer – Yes you do! – Air conditioning and building services systems require regular maintenance to ensure safety and optimum operational efficiency. Warranties are only applicable if the system or equipment is regularly maintained by an approved organisation.

To simply explain, relate this to a car which like air conditioning has many rotating and wearing parts, your warranty will not be honoured if you don’t have regular servicing (maintenance).
