Preventative Maintenance

Preventative Maintenance:

All mechanical systems need maintenance to operate correctly during their expected lifespan.  We offer a wide range of preventative maintenance services based on  the manufacturer’s guidelines and adjusted for the Vineyard environment.   Some of these services are optional and depend on the occupancy of the home or business; others are essential for the correct operation of the equipment.

Please contact Colin, our service manager, for scheduling preventative maintenance service for mechanical system.   Anything that we install we are equipped and willing to maintain.   Once Colin determines the requested scope of maintenance work desired, he will develop a quote for the work.  Once approved, he will be able to schedule a service visit with a team of two techs (one master, one apprentice).
