When DeVon Groff first started Groff’s Heating, AC & Plumbing in a modest Mountville garage back in 1987, he had one simple vision: create a locally owned company, employ and care for as many people as possible, and by extension caring about his customers.. What began as a small operation has grown into a family legacy spanning nearly four decades. Still, our core mission remains unchanged—we exist to serve our neighbors with integrity, expertise, and genuine care.
The Foundation of Family Values
Four years after DeVon started the company, master plumber Dennis Dagen joined the team, bringing plumbing expertise that would expand our capabilities. In 1993, these two visionaries formed a partnership and officially incorporated the business, laying the groundwork for what would become Lancaster County’s most trusted home service provider.
Today, both the Groff and Dagen families continue working side by side, building something far greater than a business—we’re building relationships that span generations, as one customer noted, “Great team of professionals. They know their business and are customer-centric.”
Why Service Matters More Than Sales
In an industry where many companies train their technicians to be salespeople first, we’ve chosen a different path. Our technicians are motivated to provide quality service and solutions for homeowners, rather than pushing expensive upgrades when simple repairs will suffice. We believe in a well informed homeowner that knows what all of their options are before making an expensive decision.
This approach stems from our belief that your home is your sanctuary, and you deserve honest, straightforward solutions. Whether you’re dealing with a plumbing emergency in Lancaster, PA, need HVAC repairs, or require electrical services, our team focuses on what’s truly best for your situation and budget.
More Than Just Technical Expertise
Every member of our team understands they’re not just fixing pipes or servicing air conditioners—they’re helping families stay comfortable, safe, and secure in their homes. One satisfied customer shared, “Being a widow, I had little to no knowledge of our plumbing. Logan spent a lot of time explaining things to me during his service call for my water pump. He is an excellent example of the fine people at Groff’s.”
Growing While Staying Grounded
From that single garage to our current facility on Willow Street Pike, Groff’s has experienced tremendous growth. We now employ more than 15 licensed plumbers, certified HVAC technicians, and skilled electricians, operating a fleet of over 50 trucks to serve residential and commercial customers across South-Central Pennsylvania.
Yet despite our expansion, we’ve maintained the personal touch and community connection that sets us apart. According to the U.S. Bureau of Labor Statistics, the average HVAC company experiences 80% customer turnover annually; however, our customer retention rates consistently remain higher because we prioritize relationships over transactions.
Comprehensive Services Under One Roof
Understanding that homeowners prefer working with a single, trusted provider, we’ve expanded our services to include:
- HVAC services, including installation, repair, and maintenance of heating and cooling systems
- Plumber expertise covering everything from emergency repairs to bathroom remodeling
- Electrical solutions from lighting installation to complete electrical panel upgrades
- Water treatment and conditioning systems
- Solar energy solutions for sustainable home comfort
This comprehensive approach saves our customers time, money, and the hassle of coordinating multiple contractors.
Our Commitment to Excellence
What drives us to be the best at what we do? It’s the knowledge that when your air conditioner fails on the hottest day of summer, or your pipes burst during a winter freeze, we’re the team you can count on. As one emergency customer testified, “My heater went out overnight on what will be the coldest days. My normal computer came, but it did not have the part. Called Groff’s and spoke with Adrian, who found the part for me. Tech Garrett came out within an hour, and my heat is back on. THANKS.”
Quality Materials, Guaranteed Satisfaction
Since 1987, we’ve built our reputation on using only top-quality materials and providing a 100% satisfaction guaranteed service. Whether installing a new high-efficiency HVAC system or repairing a leaky faucet, every job receives the same attention to detail and commitment to excellence.
Being locally owned and operated means we understand the unique challenges Lancaster County homeowners face—from hard water issues common in our area to the specific heating and cooling demands of Pennsylvania’s climate. Our technicians live in the communities we serve, and their reputation is our reputation.
The Heart Behind the Service
What truly sets Groff’s apart isn’t just our technical expertise—it’s our genuine care for the families we serve. Every service call is an opportunity to solve problems, provide value, and ensure our customers feel confident in their home’s comfort systems.
According to a recent Consumer Reports study, homeowners who work with family-owned service companies report 35% higher satisfaction rates compared to those who work with national chains. This statistic reflects what we see daily: when companies genuinely care about their communities, it shows in every interaction.
We’re not interested in fear-based marketing or high-pressure sales tactics. Instead, we focus on education, transparency, and providing honest communication about your options. One customer appreciated this approach, noting, “They remodeled my bathroom and I love it! Very clean and professional!”
Building Trust Through Consistency
Since 1987, we’ve seen trends come and go in the home service industry. Smart thermostats, high-efficiency systems, and tankless water heaters have revolutionized how homes operate. Through every advancement, our commitment has remained constant: deliver exceptional service with integrity and expertise.
Our longevity speaks to more than just business success—it demonstrates the trust Lancaster County families place in us. From Mountville to West Chester, York to Harrisburg, families know they can count on Groff’s for reliable, professional service.
Emergency Services When You Need Them Most
Home emergencies don’t follow business hours, which is why we provide 24/7 emergency services for urgent HVAC, plumbing, and electrical issues. Whether it’s a burst pipe flooding your basement or a furnace failure during a cold snap, our emergency hotline (717) 464-9446 connects you with real help, not an answering service.
The Environmental Protection Agency emphasizes the importance of properly functioning home systems for health and safety. When emergencies strike, having a trusted local company that responds quickly can prevent minor issues from becoming major disasters.
Innovation Meets Tradition
While we honor our traditional values of honest service and fair pricing, we’ve also adopted modern technology to serve our customers better. From online scheduling systems to advanced diagnostic equipment, we leverage innovation to improve efficiency without sacrificing the personal touch that defines our service.
Our investment in ongoing training ensures our technicians stay current with the latest industry developments. Whether it’s new refrigerant regulations, smart home integration, or energy-efficient technologies, our team brings cutting-edge knowledge to every job site.
Looking Forward, Staying True
As we look toward the future, our mission remains clear: continue providing excellent products and services while developing a team that customers genuinely want in their homes. We’re not just maintaining systems—we’re supporting the trust families place in us.
The home service industry continues evolving, with new technologies and changing customer expectations. Throughout these changes, we remain committed to the values that have guided us since 1987: integrity, expertise, and genuine care for our customers.
Your Comfort, Our Calling
At Groff’s, we understand that your home represents security, comfort, and everything you’ve worked to build. When you invite us into your home, you’re trusting us with more than just a repair or installation—you’re trusting us with your family’s comfort and safety.
That responsibility isn’t something we take lightly. That’s why we continue to invest in training, equipment, and the kind of people who share our values. It’s why we stand behind every job with our 100% satisfaction guarantee. And it’s why, after nearly 40 years, we still approach each service call with the same dedication DeVon Groff brought to that first customer back in 1987.
