Your new HVAC system will either work perfectly for decades or become your most expensive regret—the difference lies entirely in who installs it. At Groff’s Home Comfort Team, we’ve spent nearly four decades perfecting installations that actually deliver the comfort, efficiency, and reliability your family deserves, not just what sounds good in sales brochures.
Whether you’re escaping an aging system that’s draining your budget, building your dream home, or finally investing in the efficiency you’ve been promising yourself, our certified technicians treat your installation like our own family’s comfort depends on it—because in Lititz, reputation travels fast and quality work speaks louder than marketing promises.
Since 1987, DeVon Groff and Denny Dagan have built this company on a simple principle: install it right the first time, or don’t install it at all. Today, both families continue working side by side, proving that genuine care and expert craftsmanship never go out of style.
HVAC installation isn’t just about connecting equipment—it’s about engineering comfort systems that work flawlessly for decades. Our team masters every trade your installation demands, from electrical precision to refrigerant expertise, ensuring your investment performs exactly as promised.

Most HVAC installations fail because contractors skip critical steps to save time and maximize profits. At Groff’s, we follow a proven five-step process that ensures your system works perfectly from day one and continues delivering reliable comfort for decades.
Here’s how we transform installation day into years of worry-free performance:
1. Comprehensive Assessment
No guesswork, no generic estimates—our certified technicians perform precise Manual J load calculations and examine your home’s unique characteristics to determine exactly what your family needs for perfect comfort, not what’s easiest to sell.
2. Custom Recommendations
We present equipment options that actually match your situation and budget, explaining every benefit in plain English. No pressure tactics, no upselling schemes—just honest recommendations from professionals who sleep well knowing we did right by your family.
3. Transparent Pricing
Every cost is spelled out, with no hidden surprises. Most equipment replacements take 1-2 days; new ductwork installations require 3-5 days. You’ll know exactly what to expect before we start, not after we finish.
4. Professional Installation
Our EPA-certified and NATE-certified technicians handle every critical detail with precision—from refrigerant charging to safety inspections—because your family’s comfort can’t survive shortcuts or “close enough” craftsmanship.
5. Testing & Education
We don’t just install and disappear. Every component is thoroughly tested, and we teach you everything you need to know about operating and maintaining your investment, so you feel confident, not confused, about your new comfort system.
Your comfort deserves an installation that works perfectly from day one. This systematic approach ensures your HVAC investment delivers the reliable performance your family expects, not the problems that come from rushed installations and corner-cutting contractors.
Your HVAC installation will either work flawlessly for decades or become an expensive source of ongoing problems. The difference lies entirely in choosing installers who’ve proven their expertise through thousands of successful projects, not just impressive sales presentations.
Here’s what sets Groff’s installations apart from contractors who hope for the best:

Comprehensive Services

Choosing Groff’s means selecting contractors who have earned their reputation through thousands of successful installations, not marketing promises. Your family’s comfort deserves the expertise that comes from nearly four decades of doing things right the first time.
Schedule Annual Maintenance
The most expensive HVAC repair is the one that could have been prevented. Professional maintenance catches problems while they’re still cheap to fix, not after they’ve destroyed expensive components during extreme weather.
Change Filters Regularly
Dirty filters are system killers—they strangle airflow, overheat equipment, and turn efficient systems into energy-wasting disasters. Replace every 1-3 months, or watch your investment slowly destroy itself.
Keep Outdoor Units Clear
Your outdoor unit requires space to operate efficiently. Debris, vegetation, and clutter within two feet create efficiency-killing restrictions that force your system to work harder while delivering less comfort.
Monitor Performance
Strange noises, uneven temperatures, and rising energy bills are your system’s cry for help. Ignore these warning signs, and minor issues become major disasters that strike during the worst weather.
Stop settling for inadequate heating and cooling that leaves your family uncomfortable and your energy bills sky-high. Contact Groff’s Home Comfort Team today and discover why thousands of Lititz families trust us with their most important comfort investments. Your perfect climate-controlled home is just one installation away.
How much does HVAC installation cost in Lititz, PA?
Installation costs typically range from $5,000 to $12,500, with most homeowners spending around $7,500 for a standard system replacement. Costs depend on the home’s size, system type, efficiency ratings, and whether new ductwork is required. Adding ductwork increases costs by $2,000 to $5,000 for typical 2,000-square-foot homes. We provide transparent, upfront pricing during free consultations.
How long does HVAC installation take?
Most installations take 1-2 days when using existing ductwork, or 3-5 days when new ductwork is required. The timeline depends on the home’s size, installation complexity, and whether any electrical modifications are required. Simple equipment replacements are often complete in one day, while full installations with new ductwork take longer.
What size HVAC system do I need?
Proper sizing depends on factors such as square footage, insulation levels, window placement, ceiling height, and local climate conditions. Our technicians perform Manual J load calculations to determine exact capacity requirements. Installation costs range from $3 to $ 7 per square foot of conditioned space.
Do you offer financing options?
Yes, we work with financing partners offering flexible payment options. Many homeowners utilize federal tax credits for high-efficiency systems, and local utilities sometimes offer rebates. We’ll discuss all available options during the consultation.
What’s the difference between replacement and full installation?
System replacement utilizes existing ductwork and infrastructure, typically resulting in faster and less expensive installation. The complete installation includes new ductwork, electrical work, and a complete system design. Full installations cost $2,000-5,000 more but may be necessary for older homes or new additions.
