Power outages can last hours or days, leaving your home without heat, cooling, lights, or refrigeration. J&G Heating & Air Conditioning installs whole-home backup generators that automatically power essential systems when the grid fails. Whether you’re protecting your family from winter heating loss or summer heat, safeguarding food and medications, or maintaining business continuity, our Generac generator installations provide peace of mind and guaranteed backup power.
When you’re investing in a whole-home generator, professional installation matters as much as the equipment. Our experience, manufacturer certifications, and family-owned service all add up to one thing: a generator installation done right the first time, backed by people who’ll be here for maintenance and future service when you need them.
J&G Heating & Air Conditioning serves five communities across Lancaster County from our main office in Conestoga, PA. Each area receives the same quality installation workmanship, same-day emergency support if problems arise, and the same commitment to properly sized equipment and professional service.
Every whole-home generator installation we do follows the same proven process — designed to deliver properly sized equipment, professional workmanship, and a system that protects your home from day one. Tap any step below to see exactly what happens.
We evaluate your home’s electrical panel and capacity, current HVAC system (furnace, AC, heat pump), water heater type and usage, other critical loads (well pump, sump pump, medical equipment), and gas line access and capacity (for natural gas) or propane tank placement. This comprehensive assessment ensures we recommend the right generator size and fuel type for your specific needs.
During this visit, we also discuss your priorities during an outage, budget considerations, and any special requirements like medical equipment or home office needs.
Based on your assessment, we recommend generator size (kW) that matches your critical load needs, fuel type (natural gas vs. propane), placement location (typically on a concrete pad beside your home), electrical integration and circuit selection, and noise considerations with local setback requirements. We provide detailed specifications and transparent pricing.
We explain the difference between powering essential circuits versus whole-home backup, helping you choose the most cost-effective solution for your situation.
Before installation, we handle local building and electrical permits, code compliance review (Pennsylvania electrical code, setback requirements), and gas inspection coordination (if natural gas connection needed). Our team manages all paperwork and inspections to ensure your installation meets all local requirements.
We coordinate with local utilities and inspectors to streamline the approval process and prevent delays.
Our certified electricians and technicians prepare the foundation (concrete pad) if needed, install the generator unit, run gas line connections and test for leaks, install the automatic transfer switch in your electrical panel, run electrical circuits from panel to generator, test automatic startup and load transfer, and ensure proper grounding and safety disconnect.
Installation typically takes 1-2 days depending on complexity. We protect your landscaping and clean up thoroughly when complete.
We complete final walkthrough and inspection verification, fuel supply check and adjustment, monthly self-test mode configuration (generator runs a short test each month), your training on operation, maintenance, and emergency procedures, warranty explanation and support contact information. You’ll understand exactly how your system works and what to expect.
We provide comprehensive documentation including operation manual, maintenance schedule, and emergency contact information.
