Generator installation Cost and The Performance of The System Can Be Impacted By A Variety of Factors




  • The needs assessment and thorough site inspection are important steps in developing the right system design for your property or facility and cannot be completed accurately by using an online software program.  
  • Generators have combustion engines in them and require a combustion engine mechanic for reliable service during their lifespan. ​ 
  • Many generator manufacturers only require a 3 day seminar to certify a participant as a generator technician or a company as a Dealer. Make sure your installer is either a generator company or has an association with a generator company. Think of it this way...would you take your car to your electrician for repairs if he took a 2 day seminar on auto repairs? In the same respect a generator mechanic is not the best person to be rewiring the lighting in your house. Ask your contractor what the qualifications of the service staff are beyond any factory certifications. 
  • Be cautious of companies that only offer one brand. They only have one solution and it may not be the right one for your application. 
  • Many generator dealers and suppliers have no obligation to accept the manufacturers warranty burden to provide work on your generator and most will not do any warranty work if  they did not sell or install the system. 
  • Be aware that all manufacturers say they have the best equipment. Consider the cost of ownership of that equipment through its lifespan regarding parts availability, warranty administration, and software availability.  
  • Generator warranties are typically multiple years and that warranty can be null and void unless the manufacturers installation and preventative maintenance requirements are followed. All of the major manufacturers publish those parameters in their installation guides.
  • Load shedding or load management is a common practice using a smaller generator to run a larger home. Load management works, however, it is critical that the generator still be large enough to run the items important to you. A smaller generator has a nice price tag but may not run the items you expect.
  • If HVAC is important to you make sure your contractor considers the LRA (lock rotor amp) rating on your air conditioners or heat pumps so the  generator can handle the power requirement or that system will not perform well.
  • Permits and Inspections are required for just about every generator installation. If any contractor suggests otherwise contact your local officials and make sure you are getting the correct guidance.
  • Visit your contractors facility and make sure they are a fully functional company, licensed, and insured.
