5 Steps to Choosing the Right Generator for Your Home

Choosing the Right Generator For Your Home


Power When You Need It Most

Power outages can happen at any time, whether due to severe storms, aging power grids, or unexpected failures. A backup generator for your home provides security, comfort, and peace of mind by keeping essential systems running when the power goes out.

For homeowners in Maryland, where weather conditions vary, choosing the right generator requires careful consideration. This guide breaks down everything you need to know to make an informed decision about generator installation and backup power options.

1. Understand Why You Need a Backup Generator

Before choosing a generator, it’s important to understand what problems it solves and why having one matters. A residential backup power solution ensures that essential appliances and systems remain operational during an outage:

  • Uninterrupted power for lights, appliances, and security systems
  • Food preservation by keeping refrigerators and freezers running
  • Temperature control to prevent extreme heat or cold from affecting indoor comfort
  • Medical device support for those who rely on powered equipment


Homeowners in areas prone to frequent storms or utility disruptions will benefit the most from having a reliable standby power source that provides whole-home coverage.

2. Choosing the Right Generator Type

There are three main types of generators, each suited for different needs and budgets:

  • Standby Generators
    • Permanently installed and activates automatically during an outage
    • Can power an entire home or critical circuits
    • Higher upfront cost but offers the most convenience and reliability


When considering portable vs standby generators, think about how much power you need and how often outages occur. Standby models provide whole-home coverage, while portable options offer flexibility for specific appliances.

3. Our Team Will Recommend the Right Generator Size for Your Home

Selecting the correct generator size ensures your home gets enough power without overloading the system. A generator-sizing guide helps determine the right capacity by:

  • Listing essential appliances and their wattage requirements
  • Calculating both running and surge power needs
  • Choosing a generator that provides 10-20% more power than your total calculation for future use


For example, a typical household might require:

  • Refrigerator: 700 running watts, 2200 surge watts
  • HVAC system: 3000 running watts, 4500 surge watts
  • Sump pump: 1000 running watts, 2000 surge watts
  • Lights and small appliances: 500 running watts, 750 surge watts


A professional can assist with accurate load calculations to ensure your generator can handle your home’s power needs.

4. Why you Need Professional Installation and Maintenance

For standby generators, professional installation is essential to ensure:

  • Compliance with local codes and safety regulations
  • Proper electrical and fuel connections
  • Seamless integration with your home’s power system


Working with experts who specialize in Generac generator services ensures your system is installed correctly and operates at peak efficiency.

Regular generator maintenance services keep your system in top condition. A licensed technician can:

  • Inspect and replace filters, fuel lines, and batteries
  • Check for leaks or worn components
  • Test the system to confirm it’s ready for an outage


Homeowners who invest in routine service will enjoy a more reliable backup power solution for years to come.

5. Know the Answers to Common Generator Questions

Many homeowners have similar concerns when shopping for a generator. Here are the most frequently asked questions:

How often should I service my generator?

  • Standby generators: At least once a year or after every 200 hours of use.

How do I know if my backup generator is functioning properly?

  • To ensure your backup generator is working correctly, it’s important to conduct regular test operations. This involves starting the generator, checking for any fluid leaks, inspecting the battery connections, and keeping an eye out for system alerts. If you encounter problems such as slow starting, significant fluid leaks, or warning lights on the control panel, it may be time to reach out to a professional for assistance.

How can I ensure my generator is ready for a long power outage?

  • Having technicians perform regular maintenance checks is vital to being prepared for long power outages. 

Understanding these basics helps homeowners make an informed purchase decision.
