Varitech Technician

We provide Parts, as well as Service and Preventative Maintenance on all makes.


1. Parts

Varitech stocks many commonly used parts. In the event that necessary parts are not in inventory, we can often get them the next day.

2. Service

Most critical applications require standby generator systems, however they are rarely tested under full load conditions.

How much faith do you have that your system will perform in a real emergency?

We provide Load bank testing that can test your generator completely through all conditions up to and including full rated output without affecting your critical load. In addition, it helps seat piston rings, can eliminate wet stacking, removes harmful carbon deposits and helps you comply with NFPA & Joint Commission requirements, all within a controlled environment.

Varitech also offers many other services including fueling service. All services, repairs and PM’s include a detailed service report for your records. We also maintain a service file for all of our customers, in the event that yours are ever lost or destroyed.

3. Preventative Maintenance

Preventative Maintenance helps insure that your standby generator provides the security, protection and reliability that you deserve. Our customer database tracks your equipment service records. You have the peace of mind knowing that we will contact you when service is due; one less thing you have to keep track of.

At a minimum, we recommend Semi-Annual Services consisting of a Level A Inspection visit and a Level B Service visit in alternating 6-month intervals, however you can choose your level of protection.

Annual Service consists of a single Level B visit every 12 months.

What do we do during a Level B Service Visit?
  • Replace engine oil filter(s) and change engine oil.
  • Inspect, clean or replace air filter(s) as needed.
  • Replace fuel filter(s) or clean fuel strainer(s) as required.

How is a Level A Inspection different?

  • Fluids are added, not changed.
  • It costs 20% to 30% less than a Level B.
