DPC design, build and install a comprehensive range of heating, ventilation and air conditioning (HVAC) systems.

Our HVAC installations are expertly supervised by our Gas Safe (commercial and domestic), F Gas and  registered engineers, who are responsible for ensuring successful project completion.

DPC adopt a design & build approach across many sectors, offering more comfort for the client, a cleaner communications channel and transparent accountability and cost control.

Critical issues can be identified during the design & build process not afterwards when is it can become costly.  Better to identify on paper than find out in reality when both programme and cost can be highly significant.



As a company we are experienced in delivering projects which include;


• Air Handling Units •
• VRV Systems •

• Heat Interface Units •
• Commercial Plant Rooms •
• BMS Controls Systems •


Chells Doctors Surgery Stevenage

DPC completed the design, supply and installation of the HVAC package to a new build doctors surgery in Hertfordshire. 

The works comprised of two AHU’s to the roof supplying to dirty utilities, clean utilities and common areas.  A feature here was the F7 filtration installation to the minor operations suite. With strict audible levels to adhere to, the design and commissioning of the ventilation system was key to achieve the ambitious targets, whilst achieving the correct air flow rates.

Daikin air conditioning units were installed to every office, communal waiting area and treatment rooms, all controlled by a centralised controller.

The works included the supply and commission of a Trend BMS controlled system, a commercial heating and hot water plant room which consisted of 2no boilers, 1no hot water cylinder, CT pumps, VT pumps, heat meters and major leak detection system on the mains water supply.

DPC undertook the design and installation of the new ventilation and AC system to 2 floors of retail. Works included the supply and install of MVHR to the office spaces, fresh air to the retail units and passive vent to the communal corridors.

A new VRV system was installed to all offices and retail units, all wired back to a centralised controller within the plant room.

A leak detection system was installed on the refrigerant pipe work and was monitored by the BMS system.
