Keep every room perfectly comfortable without renovating your ducts. Mini-split systems offer flexibility that traditional central AC can't match. Whether you're cooling a bedroom addition, creating a dedicated office space, or upgrading your whole-home comfort, J&G Heating & Air Conditioning installs and services the latest ductless technology. Our Fujitsu Elite and Heil-certified technicians handle everything — from design through long-term maintenance — so your home stays efficient and comfortable year-round.
When you’re investing in a mini-split system, the contractor matters as much as the equipment. Our experience, manufacturer certifications, and family-owned service all add up to one thing: a ductless comfort system designed and installed right the first time, backed by people who’ll be here for tune-ups and future repairs 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 right-sized equipment and professional service.
Every mini-split installation we do follows the same proven process — designed to deliver right-sized equipment, professional workmanship, and a system that performs from day one. Tap any step below to see exactly what happens.
We visit your home and evaluate each space you want to condition. We measure room dimensions, check insulation levels, note window exposure, assess air leakage, and discuss your comfort preferences with you room by room. This consultation drives our equipment recommendations and helps us avoid oversizing (which wastes energy and increases costs) or undersizing (which leaves you uncomfortable and running the system constantly). We also identify structural challenges — where lines should run, whether interior walls limit ductwork, and how to minimize disruption during installation.
Based on our assessment, we design a layout with appropriate head units and outdoor condenser placement for maximum efficiency and aesthetic appeal. We present you with options ranging from a single-zone system for one room or space, to multi-zone setups for whole-home comfort, all available in Heil or Fujitsu quality tiers. We explain SEER ratings (seasonal efficiency), warranty terms (parts and labor coverage vary), and realistic long-term operating costs so you can choose confidently. We’ll also walk you through the aesthetic options — wall-mounted heads, ceiling cassettes, or floor units — and show examples installed in similar homes.
Our crew runs refrigerant and condensate lines through exterior walls, existing chases, or hidden ceiling spaces to minimize visual impact and protect them from weather damage. Indoor head units mount on walls at ergonomic height or in ceilings depending on your choice, positioned for even airflow without drafts. We secure the outdoor condenser on a sturdy pad away from direct sun (which reduces efficiency), high winds, and neighbors’ bedrooms to keep noise to a minimum. We use vibration-damping pads, proper electrical grounding, and refrigerant lines sized for optimal cooling and heating performance. Once everything is in place, we pressure-test all lines, evacuate the system with proper vacuum procedures, charge it to manufacturer specifications, and run full diagnostics.
Before we consider the job complete, we run the system through heating and cooling cycles under load to ensure proper operation. We show you how to use the remote controls and smartphone apps (many modern units have them), explain filter maintenance intervals based on your home’s air quality, describe seasonal adjustments that lower energy costs, and answer all questions about operation and warranty. We leave you with documentation and emergency contact information, and every installation includes a follow-up call to confirm everything is running smoothly.
We schedule your first maintenance visit within the warranty period (usually within 30–60 days) and provide flexible options for annual tune-ups or bi-annual care. A well-maintained mini-split runs quieter, cools and heats faster, uses less electricity, and lasts 15+ years. Neglected systems start leaking refrigerant, lose efficiency by 10-15% per year, and risk compressor failure — so we make maintenance easy and affordable.
