In the market for a generator instllation?

We highly recommend that you read the recently published Generator Installers PA article : 

Installing and Servicing Standby Generators... Everybody is jumping in the game

In the past few months, I have noticed that many HVAC companies and electricians have started to advertise that they service and install standby generators.  Many are claiming to be factory authorized on websites and all are claiming to be significantly experienced in the installation and service of these units. Of late, the increased frequency and duration of power outages have convinced many to take matters into their own hands and install a back up generator to protect their homes and businesses. With this increase in public interest, many new and existing service companies are entering the generator business. In the Southeastern corner of Pennsylvania, these are about 12-15 experienced standby generator dealers that have been serving the residential and light commercial market for the past 10-20 years.  They have trained a workforce of electricians and gained significant experience with machines new and older. The rest are newcomers to the business who may or may not have even attended a training class.  The Commonwealth of Pennsylvania at this time does not require a special license or any specific training for generator installation or service technicians. For the person looking into having a generator installed, in the words of the late Steve Irwin, this spells DANGER! DANGER! DANGER! (to read more click here)

Generators require professional maintenance. They are not lawnmowers. Yes, they have an engine. The difference is…instead of turning a cutting blade, they are turning a rotor. The rotor rotates courtesy of the turning crankshaft of an internal combustion engine. That engine must be precisely tuned to a much greater degree than a lawn mower, or your cars engine. The difference is that the rotary cutting blade of a mower, or the drive shaft of your car will turn, in spite of a poorly tuned engine. Yes, they will still function, albeit poorly. The efficiency of the engine governs the efficiency of the vehicle or mower. Poor efficiency will result in poor fuel economy. Poor performance. Generators are a far different story. The engine must be finely tuned because it must turn the rotor at the precise RPM.
