Comprehensive Backup Power Services Under One Roof
We can do it all—the whole house or priority circuit coverage. Explore our core electrical, mechanical, and gas contracting services below:
Turnkey Whole-House Standby Generator Installation (18kW–60kW)
Complete supply and installation of air-cooled Generac Guardian Series (18kW, 22kW, 24kW, 26kW) and liquid-cooled Generac Protector Series (27kW to 60kW) generators. Includes site grading, composite GenPad or poured concrete slab, 200A or 400A service-entrance transfer switches, fuel tie-in, startup calibration, and municipal inspection sign-off.
Essential-Circuit & Managed Power Systems (10kW–14kW)
Budget-conscious standby installations designed to back up your home's most critical circuits via a dedicated 100A or 16-circuit load-center Automatic Transfer Switch. Protects heating systems, sump pumps, 240V submersible well pumps, septic pumps, refrigerators, deep freezers, medical devices, lighting, and home office routers.
Automatic Transfer Switch (ATS) & Smart Load Management
Installation of NEMA 3R outdoor and NEMA 1 indoor Automatic Transfer Switches (100A, 200A, and dual-200A/400A configurations), main service panel upgrades, NEC 445.18 outdoor emergency disconnects, and Smart Management Modules (SMMs) that automatically shed and sequence high-amperage 240V loads like heat pumps, electric ranges, dryers, and EV chargers.
Natural Gas & Liquid Propane (LP) Fuel Line Engineering
Full BTU load calculations, Schedule 40 black iron piping, underground yellow polyethylene (PE) gas trenching with anodized risers, high-pressure 2 PSI regulator step-downs, sediment traps, flexible stainless fuel connectors, manometer dynamic pressure verification, and PECO Energy gas meter upgrade coordination.
Township Permitting, Zoning Setbacks & Code Inspections
Preparation of complete municipal permit packages across all Bucks and Montgomery County townships—including NEC Article 220 load calculations, one-line electrical riser diagrams, gas piping schematics, property-line plot plans, and HOA architectural review submissions.
Annual Preventive Maintenance, Tuning & Emergency Repair
Scheduled 100-hour / annual maintenance (5W-30 full synthetic oil & filter changes, air filters, spark plugs, valve lash adjustment, battery load testing, firmware updates, and transfer testing) plus rapid troubleshooting for Evolution/Nexus controller fault codes, stepper motors, voltage regulators, and starter failures.
Detailed Scope of Work: What Every Turnkey HGI Installation Includes
When you compare generator quotes from different contractors, always check what is actually included in the written scope. Many lowball estimates exclude gas piping beyond 5 feet, omit township permit fees, or leave you to hire a separate plumber. Here is the complete checklist included in our turnkey installations:
| Installation Discipline | Included Materials, Engineering & Field Labor | Governing Code / Standard |
|---|---|---|
| 1. Load & Site Engineering | On-site inspection of main service panel, HVAC compressor LRA ratings, well/sump pumps, gas meter CFH capacity, and property setbacks. | NEC Article 220.82 / 220.83 & Local Township Zoning |
| 2. Foundation & Pad Prep | Excavation, compacted crushed stone base, pre-cast steel-reinforced composite GenPad or custom timber-framed concrete slab. | NFPA 37 (18" structure clearance, 60" opening clearance) |
| 3. Electrical & ATS Wiring | 100A/200A Automatic Transfer Switch, copper/aluminum feeder conductors, control wiring, Schedule 80 PVC / liquidtight conduit, and ground bonding. | NEC Article 702, Article 445, Article 250 & Article 310 |
| 4. Fuel Gas Piping | Sized Schedule 40 black iron or underground PE gas piping, manual full-port shutoff valves, sediment trap (drip leg), regulator, and flex connector. | NFPA 54 / International Fuel Gas Code (IFGC) |
| 5. Start-Up & Calibration | Group 26R starting battery, synthetic oil fill, digital manometer fuel pressure test under load, 60 Hz / 240V verification, and simulated blackout transfer test. | UL 2200 & Generac Factory Commissioning Checklist |
| 6. Permits & Restoration | Filing of township electrical and mechanical permits, meeting municipal inspectors, warranty registration, and topsoil/grass restoration. | PA UCC (Uniform Construction Code) & Municipal Rules |
Preventive Maintenance & Diagnostic Repair Schedule
A home standby generator sits outdoors through 95°F summer humidity and sub-zero January wind chills, and must go from a dead cold start to 3,600 RPM full load in under 15 seconds. Routine preventive maintenance is essential to prevent dead batteries, gummed fuel regulators, or out-of-spec valve clearances when a major storm hits.
- Every 6 Months / Pre-Storm Season Inspection: Visual inspection of enclosure louvers for rodent nests or wasp debris, battery terminal cleaning and specific-gravity/CCA load test, cranking voltage drop test, oil level check, and exercise log verification.
- Annual / 100-to-200 Hour Full Tune-Up: Drain and replace crankcase oil with full synthetic 5W-30, replace OEM spin-on oil filter, replace air filter element, replace and gap spark plugs (`0.020"`–`0.030"`), test battery charger output (`13.4V`–`14.2V DC`), inspect flexible fuel hose and demand regulator vent screen, and perform a live transfer switch test.
- Every 200 to 400 Hours / Major Mechanical Calibration: Cold valve lash inspection and adjustment (`0.002"`–`0.004"` intake and exhaust on Generac OHVI / G-Force engines), stepper motor resistance check, slip-ring and brush inspection, and harmonic/frequency verification under load.
