Our quality assurance process ensures your investment delivers the comfort, efficiency, and reliability you deserve for years to come.
Does your home need a new air conditioning system?
Here are the most common situations that call for professional AC installation:
New Construction or Major Renovations: Adding cooling to a newly built home or freshly renovated space requires careful planning and expert installation to ensure optimal performance and energy efficiency.
Existing System Beyond Repair: When repair costs exceed 50% of a new system’s value, or when your current unit fails repeatedly despite professional maintenance, replacement becomes the wise financial choice.
Inadequate Cooling Coverage: Rooms that never quite reach comfortable temperatures, or homes with significant hot spots, often need appropriately sized equipment or additional cooling zones to achieve even temperatures throughout.
Rising Energy Bills: Older, inefficient systems work harder each year to maintain the same comfort levels, driving up electricity costs. Modern, high-efficiency units can dramatically reduce your cooling expenses while improving performance.
Adding Cooling to New Spaces: Converting basements, attics, or sunrooms into livable spaces often requires dedicated cooling solutions. Ductless mini-split systems excel in these applications, providing targeted comfort without extensive ductwork modifications.
Historic Home Considerations: Many beautiful older homes in Lititz lack adequate ductwork for traditional central air. We specialize in creative solutions that preserve your home’s character while delivering modern comfort, including ductless systems and high-velocity mini-duct installations.
As industry leaders, Groff’s stays at the forefront of cooling technology, offering the most advanced, energy-efficient systems available today. Our partnerships with premier manufacturers and our deep understanding of performance characteristics across hundreds of models allow us to recommend solutions that deliver exceptional comfort while dramatically reducing energy costs.
Ultra-High-Efficiency Central Air Systems: We specialize in installing premium central air conditioners with SEER ratings up to 26, representing the pinnacle of cooling efficiency. These advanced systems feature variable-speed compressors, smart controls, and sophisticated airflow management that can reduce cooling costs by 40-60% compared to older units. Many of these systems qualify for substantial utility rebates and federal tax credits that significantly offset installation costs.
Advanced Ductless Mini-Split Technology: Our expertise with ductless systems spans the industry’s most sophisticated models, including multi-zone systems with individual room control, ultra-quiet operation, and heating capabilities down to -13°F. These systems eliminate energy losses associated with traditional ductwork while providing precise comfort control that allows different family members to maintain their preferred temperatures in separate areas.
Premium Heat Pump Solutions: We install the most advanced air-source and geothermal heat pump systems available, including cold-climate models that maintain efficiency in sub-zero temperatures. These sophisticated systems provide both heating and cooling with operational costs often 50% lower than traditional heating and cooling combinations, while delivering superior comfort and air quality.
Smart Home Integration & Advanced Controls: Every installation includes integration with the latest smart thermostats and home automation systems. These advanced controls learn your family’s preferences, optimize energy usage automatically, provide detailed consumption reports, and allow remote monitoring and adjustment from anywhere. Many systems can even detect and adjust for changing weather conditions before they affect your comfort.
When investing in a new air conditioning system, choosing the right contractor is crucial for your family’s comfort over the next 15-20 years. As Lancaster County’s most established and respected HVAC company, Groff’s has earned its position as the region’s premier AC installation specialists through consistent excellence, industry leadership, and an unwavering commitment to customer satisfaction.
Four Decades of Proven Excellence: Since DeVon Groff founded our company in 1987 with a vision to provide superior locally-owned HVAC services, we’ve grown into Lancaster County’s largest and most trusted home comfort team. When Denny Dagan joined several years later, both families committed to building a legacy based on exceptional workmanship, honest communication, and genuine care for our neighbors. Today, we operate a fleet of over 50 service vehicles staffed by more than 15 licensed plumbers and dozens of certified HVAC technicians, representing the largest, most experienced team in the region.

This deep local expertise allows us to recommend solutions perfectly tailored to our region’s conditions and housing styles.
Advanced Installation Capabilities: As industry leaders, we maintain capabilities that smaller contractors simply cannot match. Our state-of-the-art diagnostic equipment, specialized installation tools, and comprehensive inventory allow us to handle the most complex projects with precision and efficiency. Whether you need custom ductwork fabrication, multi-zone system design, or integration with existing smart home systems, our team has the expertise and resources to deliver exceptional results.
Transparent, Pressure-Free Consultation Process: Unlike companies that rely on high-pressure sales tactics or commission-driven recommendations, our approach focuses on education and honest guidance. Our certified comfort advisors take time to understand your specific needs, explain all available options in clear terms, and help you make informed decisions based on your priorities and budget. You’ll never feel pressured to purchase equipment you don’t need or can’t afford—we believe the right system sells itself when you understand how it improves your family’s comfort and reduces your energy costs.

1. How long does an AC installation typically take?
Most residential AC installations in Lititz take 8-12 hours to complete, depending on the complexity and scope of your project. As industry leaders with extensive experience, we’ve streamlined our installation process to maximize efficiency while maintaining our exacting quality standards. Simple system replacements with existing ductwork typically finish within a single day. In contrast, comprehensive installations requiring new electrical work, ductwork modifications, multi-zone configurations, or smart home integration may need additional time to ensure perfect results. Our project managers provide detailed time estimates during your consultation and keep you informed throughout the installation process, ensuring minimal disruption to your daily routine.
2. What size air conditioner do I need for my home?
Proper AC sizing requires professional Manual J load calculations that consider dozens of factors affecting your home’s cooling requirements. As industry leaders, we use advanced software and diagnostic tools to analyze your home’s square footage, insulation levels, window efficiency, orientation, ceiling heights, occupancy patterns, and local climate conditions. This comprehensive approach ensures your new system is perfectly sized for optimal comfort, energy efficiency, and equipment longevity. Oversized units waste energy, provide poor humidity control, and cycle on and off frequently, while undersized systems struggle to maintain comfortable temperatures and run constantly. Our certified technicians perform these detailed assessments to determine the exact capacity your home needs for superior performance and maximum efficiency.
3. How can I make my new AC system more energy efficient?
Modern ultra-high-efficiency air conditioners (18+ SEER rating) can reduce cooling costs by 40-60% compared to older units, representing the most significant efficiency improvement available. As industry leaders, we specialize in advanced efficiency technologies, including variable-speed compressors, smart controls, and sophisticated airflow management systems. Additional efficiency improvements include proper system sizing through detailed load calculations, precision installation by certified technicians, advanced programmable thermostats, regular professional maintenance, high-quality air filtration, properly sealed and insulated ductwork, and comprehensive home weatherization. Our energy efficiency specialists evaluate your specific situation and recommend the most cost-effective improvements based on your home’s characteristics, your usage patterns, and your budget priorities.
4. Do I need permits for AC installation in Lititz?
Yes, most AC installations in Lititz require permits to ensure work meets local building codes, electrical standards, and safety requirements. As established industry leaders, Groff’s handles all permit applications, inspections, and code compliance documentation as part of our comprehensive installation service. Our licensed technicians are thoroughly familiar with Lancaster County building requirements, electrical codes, and HVAC regulations, ensuring your installation meets or exceeds all applicable standards. This professional approach protects your investment, ensures your family’s safety, maintains your home’s insurance coverage, and provides documentation for future reference or resale purposes.
5. What’s the difference between central air and ductless mini-split systems?
Central air conditioning uses a network of ducts to distribute cooled air throughout your home from a single indoor unit, making it ideal for homes with existing ductwork and open floor plans. These systems provide consistent whole-home comfort and can integrate with advanced air filtration and humidity control systems. Ductless mini-split systems use individual indoor units connected to an outdoor compressor, offering greater installation flexibility, precise zone control, and exceptional energy efficiency by eliminating duct losses. As industry leaders, we specialize in both technologies and can recommend the optimal solution based on your home’s characteristics, existing infrastructure, comfort preferences, and energy efficiency goals. Many homes benefit from hybrid approaches that combine both technologies for maximum comfort and efficiency.
