Quick answers

Generator Installation in New Canaan, CT — What to Know

Get clear, straight answers to the most common questions Fairfield County homeowners ask before booking.

How much does a whole house generator cost in New Canaan CT?

A complete standby generator installation in New Canaan ranges from $8,000 to $20,000+ depending on generator size (14kW–48kW), fuel type, site preparation, and electrical work complexity. This includes the generator unit, concrete pad, automatic transfer switch, gas line connection, electrical wiring, permits, and inspections. Natural gas units are most common in Fairfield County because they connect to your existing gas line and never need refueling.

Generac vs Kohler — which is better for Connecticut homes?

Both Generac and Kohler are excellent choices for Connecticut. Generac has a larger service network and slightly lower upfront costs, making it the most popular choice in Fairfield County. Kohler generators are known for their commercial-grade engines and quieter operation (68 dB vs 74 dB). For homes under 4,000 sq ft, either brand works well. For larger estates, Kohler’s liquid-cooled models offer superior longevity.

What size generator do I need for a 3,000 sq ft house?

A 3,000 sq ft home in Fairfield County typically needs a 22–24kW generator to power the full 200A electrical panel, including central air conditioning. If you only need to cover essentials (lights, fridge, sump pump, Wi-Fi, a few outlets), a 14–16kW unit is sufficient and costs significantly less. We perform a detailed load calculation during the free site assessment.

How long does it take to install a whole-home generator?

On-site installation typically takes 1–2 days. The full project timeline from signed quote to a running, permitted generator is usually 2–4 weeks. This accounts for permit processing, equipment delivery, concrete pad curing (3–7 days), gas line coordination with your utility or plumber, electrical wiring, and the final municipal inspection.

Generator Installation — Frequently Asked Questions

How much does a whole-home generator cost in New Canaan, CT?

A complete standby generator installation in New Canaan typically ranges from $8,000 to $20,000+. The price depends on generator capacity (14kW for essentials up to 48kW for full-home coverage), fuel type (natural gas is most common in Fairfield County), site preparation, electrical panel capacity, and automatic transfer switch requirements. We provide a free on-site assessment with an itemized quote — no surprises.

Generac vs Kohler — which generator is better for Connecticut?

Both are excellent. Generac is the most popular choice in Fairfield County — they have the largest dealer network, competitive pricing, and strong warranty support. Kohler generators use commercial-grade engines, run quieter (68 dB vs 74 dB), and are preferred for larger homes. We install both brands and will recommend the right fit based on your home size, budget, and noise preferences.

How long does generator installation take?

Most residential installations are completed in 1–2 days of on-site work. The full timeline from signed quote to running generator is typically 2–4 weeks, which includes permitting, equipment delivery, concrete pad curing, gas line coordination, electrical wiring, and the final municipal inspection.

Do I need a permit for a generator in New Canaan?

Yes. New Canaan requires both an electrical permit and a building permit for standby generator installations. If a gas line is being run or extended, a plumbing/gas permit is also required. We handle all permitting and inspections so you don’t have to.

What size generator do I need for my home?

It depends on what you want to power. A 14–16kW generator covers essentials (lights, refrigerator, sump pump, some outlets, and Wi-Fi). A 22–24kW generator covers a full 200A panel including central AC. Homes with 400A service, pools, or electric heat may need 36–48kW. We do a load calculation during the free site assessment to size it correctly.

How often does a standby generator need maintenance?

Manufacturers recommend service every 6–12 months or 200 hours of run time, whichever comes first. Maintenance includes oil and filter changes, spark plug inspection, battery testing, coolant checks (liquid-cooled units), and a full-load test run. We offer annual maintenance plans with priority scheduling.

Will a generator increase my home’s value?

Yes. According to a Remodeling Magazine cost-vs-value study, a whole-home standby generator recoups roughly 50–75% of its cost at resale and can increase a home’s market value by $3,000–$5,000+. In storm-prone areas like Fairfield County, buyers view it as a major selling point.
