Choosing the Right Home Generator: Air-Cooled vs. Liquid-Cooled Systems Explained

What’s the Cost of a Home Generator Installation?

The cost of installing a home generator can vary based on capacity, power needs, and installation requirements. From thousands of successful installations, we know it’s definitely not a one-size-fits-all scenario. That’s why the quality, professionalism, and the expertise of your installer and service provider is essential when it comes time to understanding your options.


Choosing an experienced professional
– one who understands your needs as a homeowner – ensures that your whole house generator is safe, reliable, and worry-free for you and your family. 

What Factors Impact the Cost of a Home Generator?

Factors that can influence the total cost include the type and size of the generator, the power source, the type of start, and any associated cost of labor and permits.


While the upfront cost of installing a whole house generator for homeowners can vary, the lasting benefits include:

  • Safety & Comfort: Powers critical systems including HVAC, lighting, and security during outages.
  • Peace of Mind: Ensures continuous operation during emergencies, protecting your family.
  • Property Value: Increases home value by up to 5%.
  • Cost Savings: Prevents food spoilage and reduces insurance claims.
  • Environmental Impact: Natural gas and propane options offer reduced carbon emissions.

What Type of Generator Should I Get?

The experts at Mid-Atlantic will help guide you through the process of choosing the right generator for you. 


For homeowners wondering about the difference: A generator's RPM (rotations per minute) affects how it performs. While air-cooled generators run at 3600 RPM and stay cool using the surrounding air (no antifreeze needed), liquid-cooled systems come in both 1800 and 3600 RPM versions. 


Your choice between these systems will depend on your specific power needs and installation requirements.

Savings Beyond Peace of Mind

We get it - insurance feels unnecessary until disaster strikes. The same goes for backup power. Beyond peace of mind, many insurance companies provide 5-10% discounts on homeowner's policies with proper backup power. 


During extended outages, generators prevent costly food spoilage ($200-$400), hotel stays ($100s per night), and potential water damage from frozen pipes ($10,000+).

How Much Power Do I Really Need from a Home Generator?

Your home's unique power needs require thoughtful consideration when selecting a generator system. While some providers advertise misleadingly low installation costs, the reality is more nuanced.


A comprehensive generator solution involves carefully matching the right capacity with professional installation. The investment varies significantly based on your specific requirements and chosen system quality.


What matters most is selecting a system tailored to your specific situation. We assess:

  • Your critical power needs during outages
  • Home square footage and electrical demand
  • Fuel availability and preferences
  • Future expansion possibilities


Rather than compromising with underpowered solutions that may leave you vulnerable during emergencies, we design systems that deliver reliable performance when you need it most. Our consultation process ensures you receive the appropriate capacity for your situation, neither paying for excess power nor discovering insufficient coverage during an outage.



Let's discuss your specific needs to find the right balance of protection and investment for your home's power security.


Here a few essential components that can affect total installation cost:

  • Concrete mounting pad
  • Automatic transfer switch
  • Natural gas line installation
  • Propane tank and installation (if applicable)


The right investment is especially valuable in areas with frequent outages. A reliable generator increases property value and most homeowners recover costs within 5-10 years through prevented losses and maintained quality of life.
