Services We Offer

Preventative Maintenance Inspection Agreement:

The Preventative Maintenance Inspection Agreement is for a one year period. The Agreement includes time, mileage and parts listed. The agreement has two parts, an operation check and service. The operation check is at the top of the list, the service is at the top and the bottom. Everything listed on the checklist is completed and signed by the mechanic. If something is requested by the customer that isn’t on the list it will be added to the checklist and the price will be adjusted before customer signatures. Nothing will be done on an if needed basis, if it is on the checklist it gets done or we will back out for free. If a problem is found by the mechanic, he will notify the customer and get permission to fix it. If work is done at that time then the customer will pay for parts and labor only. If the problem requires more time or labor to finish the service then the customer will pay for travel time and mileage for us to return and finish the checklist. In the case of a mechanic being pulled away for a break down somewhere else, the customer will not have any additional costs. The Preventive maintenance service is set up to give your generator years of service with the reliability you demand. Each component of the generator and transfer switch is looked at and checked by a mechanic. When you sign the Agreement, you the customer will get a $25.00 an hour break on scheduled repairs and services, during regular service hours. The contract also gives you priority during major storms and outages.

Installation and Consultation:

If you are thinking of installing a generator there are many options to choose from, and ways to accomplish it. With having a company that services generators for a living set it up and install it, you will be given the best install to guarantee 100% operation of the generator. West Generator Services strives to install and maintain your emergency system as one of the best in the business.

Exhaust Systems:

Engine exhaust is a dangerous gas that has to be vented outside with the proper size pipe and condensation / rust traps. With generator vibration a stainless steel flex is recommended from engine to Y pipe connection. Very short exhaust systems such as outside units do not need Y pipe condensation / rust trap for the entire system gets hot enough to dry it out during weekly exercise. A exhaust system in a building needs this protection for long life of engine and muffler parts. Because exhaust system can reach temperatures of 800 to 1000 degrees wrapping the pipe in insulation is recommended.


In the way you look at reconditioning a generator is the key to doing the job correctly. Over time all components break down and start to fail, that’s why replacing one thing may not be the best way. We take history of each make and model into consideration and try to come up with the best recommendation for each customer. The end result has to be a good dependable generator for the money.

Load Bank Testing:

Generators are designed to run best at 100% load. A load bank test is the best thing you should do to a generator that spen\ds most of its life not running. The load bank test will tell you two things, is the generator in good enough shape to handle what it was made to, and was it installed correctly. On a generator that does not have high percentage of load, it is good to load test at least every few years.


The fuel system is one of the most important systems on the engine, which makes the day tank critical. There are a lot of factors that determine the size of the tank, On some engines 80% of the fuel is returned to keep the fuel under 95 degrees Fahrenheit so the engine does not have a power loss. If the tank can’t absorb the heat from the engine, the generator will slow down and possibly damage the equipment hooked to it. The tanks are under new laws all the time that keeps us changing the way we set them up. Our federal government now calls diesel a contaminated waste if spilled into the ground and if your system is pumping fuel out of a supply tank that could spell trouble. We use universal alarms and monitor to keep the level right and let you know of a problem.

Remote Radiators:

Generators are typically set up with a direct drive pusher fan off the water pump. The fan is sized to pull all the heat off the generator windings, exhaust manifolds and coolant to the outside of the building, in the process the generator room turns into a wind tunnel. On below freezing days everything in the room goes to outside temperature that is why no water pipes are recommended in the rooms including wet fire sprinkler. The benefits of a remote radiator are Fan noise, vibration and 80% of airflow is outside of the building.

Block Heaters:

The block heater is very important all year long because a generator will be at 100% load within 10 seconds from getting a start signal. In most cases the engine does not even have oil pressure when its running at full RPMs. When steel is cold it is brittle, steel engine parts at 1800 RPMs, no oil pressure at room temperature is not the best for the engine. Factory recommendation is to keep the engine temperature around 100 degrees Fahrenheit.

Battery Chargers:

The starting battery is the most critical part of the automatic start system. Dead batteries are one of the most common generator failures in this industry. The job of the battery charger is to keep the battery voltage at its proper level. Older battery charger do not turn them selves on and off to keep for cooking the batteries dry, a dry battery can and will explode doing damage to anything next to it including humans.

Electronic Governors:

In today’s world, computers are an everyday necessity, and run equipment for everything we do. More and more computerized loads on the back up generators demand closer tolerances in electrical power. An electronic governor will keep your Hz. within 0.05%, enough to hold a UPS system. An electronic governor can be installed on any generator with a flywheel ring gear. The system takes a day to put on and will make the generator except loads much faster.

Announciator Panels:

Having your emergency power system monitored 24 hours a day gives you the fastest response to a problem. A Announciator is a alarm panel that is mounted in a place that is manned 24 Hours a day so proper assistance can be called. The Announciator monitors the engine controls and fuel status with or without running.
