Why Ask Generator Advisor Exists
Buying a Standby Generator Shouldn't Begin With a Sales Appointment
A wrong-sized or badly installed generator isn't a minor mistake — it's a $10,000–$15,000 decision, and a safety issue for your family if it's done wrong.
Most homeowners only buy one standby generator in their lifetime. Yet they're often expected to choose size, fuel type, and electrical setup before a licensed electrician has ever looked at their home — based on a sales pitch, not sound advice.
Ask Generator Advisor exists to close that gap. Start with Sully. Get straight answers grounded in decades of real electrical and generator installation experience — sizing, safety, code requirements, real cost ranges — before anyone sets foot on your property.
Once you've chosen the direction that's right for you, Sully can help schedule a licensed electrician to visit your home (if you're within the service area) to verify your electrical system, confirm equipment sizing, determine the best generator location, evaluate site conditions, and provide a final installation proposal tailored to your home's unique requirements.

Investment
How Much Does a Whole-Home Generator Cost?
Every home is different, so there isn't a one-size-fits-all price. The size of your home, your electrical panel, fuel source, and what you want to keep running all affect the final investment.
The good news? You don't have to figure it out yourself. Sully will help you understand your options, explain what affects the cost, and provide a realistic investment range before scheduling your professional on-site evaluation.
Rather than giving every homeowner the same generic estimate, Sully provides a personalized ballpark investment range based on your home's needs before you schedule an on-site evaluation.
What Affects the Cost?
- Home size and electrical load
- What you want powered during an outage
- Natural gas or propane
- Electrical panel upgrades (if needed)
- Transfer switch and installation requirements
- Local permitting and code requirements
Frequently Asked Questions
Common Questions About Whole-Home Generators
How do I know what size generator I need?
The right size depends on your home's electrical load, heating and cooling system, well pump, medical equipment, and the appliances you want to keep running. Sully can help you estimate the right size before scheduling your on-site evaluation.
Do I need natural gas or propane?
Most whole-home standby generators run on either natural gas or liquid propane. The best choice depends on what's available at your home and how you want your backup power system to operate.
Will a whole-home generator power my entire house?
In many cases, yes. The right-sized standby generator can automatically power your home's essential systems — or your entire home — depending on your electrical needs and the generator selected.
How long does installation take?
Every installation is different, but once your on-site evaluation is complete, your installer will provide a timeline based on permitting, equipment availability, and your home's electrical requirements.
Can Sully recommend the right generator for my home?
Sully can recommend the best options based on the information you provide. However, every installation is confirmed during a professional on-site evaluation to ensure your generator is properly sized and installed safely.
What towns does Ask Generator Advisor serve?
Ask Generator Advisor serves homeowners throughout Central Massachusetts, including Worcester, Milford, Framingham, Uxbridge, and surrounding communities.
Can a standby generator increase my home's value?
A professionally installed standby generator may increase buyer appeal and perceived home value, especially in areas where outages are common. The exact impact depends on the home, market, installation quality, and buyer priorities.
What's the difference between air-cooled and liquid-cooled generators?
Air-cooled generators are common for many residential installations and are typically more cost-effective. Liquid-cooled generators are often used for larger homes, heavier loads, or situations requiring more capacity.
Can I finance a standby generator installation?
Financing options may be available depending on the installation partner, project scope, and homeowner qualification. Sully can help you understand the likely investment range before you ask about financing.
Do standby generators require maintenance?
Yes. Standby generators should be maintained regularly so they are ready when an outage occurs. Maintenance needs vary by model, usage, and manufacturer recommendations.
What happens during a power outage?
A standby generator senses the outage, starts automatically, and transfers selected circuits or the whole home to generator power through an approved transfer switch. When utility power returns, the system transfers back automatically.
How often do standby generators test themselves?
Many standby generators run a brief automatic exercise cycle on a regular schedule. The exact timing and frequency depend on the model and settings.
