HGI Gives You Complete Control of Your Power. With over 39+ years in the electric and gas utility business, Home Generator Installations, LLC is the trusted local specialist for permanent automatic backup power in Feasterville-Trevose, Bucks County, and Montgomery County, Pennsylvania. Whether you need full whole-house coverage or priority circuit protection, our licensed team delivers code-compliant electrical and gas installations built to weather every storm.
Severe weather in the Delaware Valley—from summer derechos and tropical storm remnants to winter Nor'easters and freezing rain—regularly brings down overhead utility lines across heavily wooded neighborhoods in Bucks and Montgomery Counties. When a neighborhood transformer fails or a tree limb snaps a primary feeder line, portable gasoline generators leave families struggling with extension cords, stale fuel, carbon monoxide hazards, and manual starting in the dark. A permanently installed automatic standby generator eliminates those risks altogether.
Hands-free automatic start-up, operation, and shutdown make retaining electricity so simple that you don't even have to be home for the system to work. Your Automatic Transfer Switch (ATS) monitors utility voltage 24 hours a day and restores power within seconds of a blackout.
Generac offers models that operate at lower speeds during Quiet-Test self-exercise modes and utilize sound-attenuated aluminum enclosures with G-Force pressure-lubricated engines to reduce noise while providing continuous 240V/120V power for high-demand appliances.
You can rest assured that your refrigerator and deep freezer will continue to keep your food cold and prevent spoilage even if you are away on vacation. Basement sump pumps stay active during torrential rain, and heating pipes never freeze during winter outages.
We do great work and it shows in our homeowner reviews across HomeAdvisor and Angie's List. Every installation is personally overseen with 39+ years of electric and gas utility expertise, ensuring clean conduit runs, proper gas pressure, and passed township inspections.
Check out some of our happy installations! We can do it all—the whole house or priority circuit coverage. Below are actual field photographs from residential projects completed by Home Generator Installations, LLC, illustrating clean outdoor Automatic Transfer Switch mounting, PECO natural gas meter tie-ins, pressure regulators, and composite GenPad foundations.
Installed adjacent to the existing natural gas meter and outdoor electrical disconnect. Features rigid Schedule 40 galvanized gas piping with sediment trap, flexible fuel connector, and pre-cast GenPad concrete-composite leveling base.
Complete exterior utility integration showing the weatherproof NEMA 3R Generac Automatic Transfer Switch mounted beside the utility electric meter socket, paired with regulated natural gas supply piping and liquidtight conduit.
Precision placement in a residential utility corridor alongside central air conditioning equipment, maintaining full NEC working clearances, proper exhaust orientation, and direct connection to both gas and electric meters.
Where sloped landscaping required grade stabilization, our crew built a pressure-treated timber retaining border around a reinforced concrete pad, with elevated Generac transfer switch and gas meter manifold on the stucco wall above.
Engineered for a larger single-family residence requiring NFPA 37 clearance from basement windows. Rigid conduit and fuel piping are neatly supported along the foundation wall to the generator placement pad.
When you need 24/7 protection against the elements: complete 22kW Generac Guardian installation with exterior transfer switch, gas regulator tie-in, timber-bordered concrete slab, and full topsoil/seed restoration around the work zone.
Installing a residential standby generator is far more involved than setting an appliance on a patio. A permanent backup power system connects directly to two of the most critical infrastructures in your house: your main 120/240-volt electrical service entrance and your pressurized natural gas or liquid propane (LP) fuel supply. Every calculation—from conductor ampacity and ground-rod bonding to gas pipe internal diameter and regulator BTU capacity—must be executed accurately so the generator performs reliably under peak storm load.
At Home Generator Installations, LLC, owner Stephen O'Donnell draws upon more than 39 years of hands-on utility and electrical contracting experience across Bucks and Montgomery Counties. Instead of splitting responsibility between separate electrical and plumbing subcontractors, our team designs and installs the entire system under one roof.
Before selecting a generator model, we evaluate how your family uses electricity during an extended outage and inspect your main breaker panel, HVAC data plates, and well or sump pump ratings:

One of the most common mistakes made by inexperienced installers is tapping an undersized house gas line without calculating total connected BTU load and pipe friction loss. A 22kW to 26kW standby generator requires up to 327,000 to 350,000 BTU/hr of natural gas under full electrical load—often more than your furnace, water heater, gas dryer, and cooktop combined!
Standard residential natural gas service in Bucks and Montgomery Counties operates at low pressure (typically 5 to 7 inches of water column [W.C.], or roughly 0.25 PSI). If your existing gas meter is a standard 250 CFH diaphragm meter and your furnace (100,000 BTU), water heater (40,000 BTU), and new 22kW generator (327,000 BTU) run simultaneously during a January blizzard, an undersized meter or 1/2-inch pipe will starve the generator of fuel, causing the furnace flame to drop out or the generator to shut down on an under-speed/under-voltage fault.
How HGI Solves This: During your free on-site assessment, we inspect your gas meter badge rating, measure static and dynamic pressure with a digital manometer, size Schedule 40 black iron or underground polyethylene (PE) piping according to NFPA 54 / IFGC tables, and coordinate any required PECO gas meter upgrade (such as upgrading an AC-250 meter to a 425 CFH or 630 CFH meter) before commissioning.
Every municipality in Bucks County and Montgomery County enforces strict building, electrical, and zoning rules for permanent outdoor power equipment. We handle all permit applications, plot plans, load calculation sheets, and one-line electrical diagrams required by local code officials:

When utility power drops out, the automatic transfer switch senses the loss of grid voltage immediately. After a 5-to-10-second verification delay to ensure the outage is not a momentary utility flicker, the standby generator starts its engine, stabilizes at 3,600 RPM (60 Hz), and transfers your home's electrical load automatically—typically restoring power within 10 to 20 seconds without any manual intervention.
For essential-circuit coverage (refrigerator, sump pump, furnace blower, well pump, and lighting) in a 1,500 to 2,500 sq. ft. home, a 14kW to 18kW standby generator is common. For full whole-house backup covering central air conditioning (3 to 5 tons), electric appliances, and all branch circuits in a 2,500 to 4,500 sq. ft. home, most homeowners select a 22kW, 24kW, or 26kW air-cooled Generac Guardian system.

Your generator can be programmed to run a brief 5-to-12-minute self-diagnostic exercise weekly, biweekly, or monthly at a reduced Quiet-Test RPM to circulate oil, charge the 12V starting battery, and verify controller readiness without transferring house loads. Preventive maintenance (synthetic oil change, oil filter, air filter, spark plugs, battery load test, and valve lash check) is recommended annually or after every 100 to 200 hours of continuous outage runtime.
