Your family’s comfort isn’t something to gamble with, and you need technicians who understand the urgency. At Groff’s Home Comfort Team, we’ve established ourselves as Lancaster County’s premier AC repair specialists for nearly four decades—and we know that genuine service means showing up ready, working with integrity, and delivering results that last.
As one of the most trusted HVAC companies in Pennsylvania, we’ve built our reputation on a simple promise: when other companies make excuses, we make it happen. Whether you’re dealing with warm air blowing from your vents, strange noises from your outdoor unit, or a system that won’t start at all, our award-winning team responds with the speed and precision your family deserves. We’re not just fixing air conditioners—we’re restoring the comfort that makes your house feel like home again.
What sets us apart as an industry leader: Over 50 trucks in our fleet, more than 15 licensed technicians, and thousands of satisfied customers across South-Central PA. When you choose Groff’s, you’re partnering with a company that has mastered every aspect of AC repair and earned recognition as one of the region’s most dependable home service providers.
Summer heat in Lititz doesn’t negotiate, and neither should you when it comes to choosing an AC repair company. As the region’s leading HVAC specialists, our certified technicians carry advanced diagnostic tools and standard replacement parts on every truck, which means faster repairs and immediate relief when your cooling system fails.
We’ve earned our reputation as one of Pennsylvania’s top AC repair companies by mastering the art of emergency cooling restoration. While other companies guess at solutions, we diagnose problems with precision and fix them permanently the first time.
These common AC problems demand the expertise that only industry leaders can provide:
Refrigerant Leaks – Low refrigerant levels cause your air conditioner to blow warm air and work inefficiently. Our technicians locate leaks, repair them properly, and recharge your system to optimal levels so you feel the difference immediately.
Compressor Failures – The compressor is your AC’s heart, and when it fails, your entire cooling system stops working. We diagnose compressor issues accurately and recommend the most cost-effective solution, whether that’s repair or replacement.
Electrical Component Failures – Capacitors, contactors, and other electrical components wear out over time, causing your AC to malfunction or fail to start. Our technicians carry these standard parts to quickly restore operation.
Frozen Evaporator Coils – When airflow restrictions or refrigerant issues cause your indoor coil to freeze, your system stops cooling entirely. We identify the root cause, safely thaw the coil, and fix the underlying problem.
Thermostat Malfunctions – A failing thermostat can cause short cycling, poor temperature control, or complete system failure. We repair or replace faulty thermostats and calibrate them for accurate operation.
Dirty Condenser Coils – Pennsylvania’s humidity and seasonal pollen buildup can clog your outdoor unit, forcing it to work harder and cooling less effectively. We clean condenser coils thoroughly and restore efficient heat transfer.
At Groff’s Home Comfort Team, we didn’t become one of Lancaster County’s most respected HVAC companies by accident. We’ve earned our position as an industry leader through decades of consistent excellence, unwavering integrity, and a commitment to serving others that runs deeper than profit margins.
How we serve others reflects our core values. We’ve built our business on principles of integrity, respect, and excellence—guiding everything we do, from how we care for your home to how we train our team.
Doing what’s right even when no one is watching. Over-delivering on expectations because our customers deserve excellence. Educating, not pressuring—so homeowners feel confident in every decision. Serving others well, because we’re called to love our neighbors in everything we do.
This isn’t a slogan. It’s our standard. And it’s why we’ve grown from a small garage operation in 1987 to one of South-Central Pennsylvania’s most trusted home comfort companies.

While our team stands ready to handle any AC emergency with industry-leading expertise, we believe the best repair is the one you never need.
As stewards of our customers’ long-term comfort and investment, we share these professional preventative strategies that our decades of experience have proven most effective:
Change Your Air Filters with Precision – This seemingly simple task has the most significant impact on your system’s performance and longevity. As industry experts, we recommend checking filters monthly and replacing them every 1-3 months, depending on your home’s specific conditions. Homes with pets, family members with allergies, or nearby construction may require more frequent changes to maintain optimal performance.
Maintain Your Outdoor Unit Like a Professional – Your air conditioner’s outdoor unit requires adequate clearance to operate at peak efficiency. Remove leaves, grass clippings, and debris regularly—something many homeowners overlook until it’s too late. Maintain at least two feet of clearance on all sides, and trim vegetation that could restrict airflow.
Partner with Industry Leaders for Annual Maintenance – Routine professional maintenance can identify and resolve vulnerabilities before they become expensive emergencies. Our comprehensive maintenance agreements include thorough inspections of refrigerant levels, electrical components, and overall system performance to ensure everything operates at peak efficiency and safety.
Monitor System Performance with Expert Eyes – Pay attention to subtle changes in cooling performance that untrained homeowners might dismiss as usual. Strange noises, inconsistent airflow, or slight temperature variations often signal developing problems. Our experience has taught us that catching issues early typically means more straightforward, more affordable repairs.
Trust Professional Expertise – While homeowners can handle basic maintenance tasks, complex diagnostics and repairs should always be left to certified professionals. Attempting DIY repairs on modern cooling systems can void warranties, create safety hazards, and turn minor problems into major expenses.
As one of the region’s most trusted HVAC authorities, we frequently help homeowners navigate this critical decision. The choice between repairing and replacing your AC system requires careful analysis of multiple factors, and our decades of experience provide an invaluable perspective that generic contractors simply cannot match.
Generally, if repair costs exceed 50% of replacement cost, or if your system is over 15 years old and requires frequent repairs, replacement often makes superior financial sense. However, this decision requires expert evaluation that considers your home’s specific needs, local climate demands, and long-term comfort goals.
Modern high-efficiency systems offer dramatically improved energy efficiency compared to older units—improvements that can offset the initial investment through substantially lower operating costs. As authorized dealers for premium brands like Carrier, Trane, and Lennox, we have access to the most advanced cooling technologies available.
Our team provides comprehensive assessments and detailed cost analyses to help you make the most informed decision for your situation and budget. We never push products you don’t need—instead, we provide expert guidance that enables you to invest wisely in your family’s long-term comfort.
How often should I have my air conditioner serviced in Lititz?
As industry leaders with nearly four decades of experience, we recommend professional AC maintenance at least once per year, typically in the spring before Pennsylvania’s intense summer heat arrives. Annual maintenance by certified professionals helps ensure optimal performance, prevents unexpected breakdowns, and significantly extends your system’s lifespan. Homes with heavy usage, pets, or elevated dust levels may benefit from our twice-yearly service programs. Our comprehensive maintenance agreements provide the expert care your investment deserves.
What are the most common signs my AC needs professional repair?
Our extensive experience diagnosing cooling systems has revealed consistent warning patterns: warm air from vents, weak airflow throughout the home, unusual mechanical noises (grinding, banging, or squealing), excessive indoor humidity, frequent system cycling, unexplained increases in energy bills, water leaks around the unit, and strange odors from vents. If you notice any of these symptoms, our expert technicians can diagnose and resolve the issue before it becomes a costly emergency.
How much does professional AC repair typically cost in Lititz?
Repair costs vary significantly depending on the specific problem, required parts, and labor complexity. Simple repairs like capacitor replacement or coil cleaning may cost a few hundred dollars, while major component replacements require larger investments. As industry leaders committed to transparency, we provide detailed, upfront pricing before any work begins, ensuring you understand exactly what to expect with no hidden fees or surprise charges.
Should I repair or replace my aging air conditioning system?
This critical decision requires expert analysis that considers multiple factors: your system’s age, repair history, current efficiency, and long-term cost projections. If your AC is over 15 years old, requires frequent repairs, or repair costs exceed 50% of replacement cost, replacement typically delivers superior long-term value. Modern high-efficiency systems offer dramatically improved energy performance that can substantially reduce monthly operating expenses. Our certified professionals provide comprehensive assessments and detailed cost analyses to help you make the most informed investment decision.
How can I improve my air conditioner’s efficiency and prevent expensive repairs?
Professional maintenance represents the most effective strategy: monthly filter changes, maintaining clear outdoor unit surroundings, annual professional tune-ups by certified technicians, and monitoring system performance for unusual behaviors. Additionally, maintaining consistent thermostat settings, sealing air leaks throughout your home, and ensuring proper insulation help your AC operate more efficiently and last significantly longer. Our preventive maintenance programs provide expert care that maximizes both efficiency and longevity.
As one of the region’s premier home comfort specialists, we don’t just repair air conditioners—we restore the reliable comfort your family deserves, backed by nearly four decades of proven excellence and a commitment to service that goes far beyond the typical contractor experience.
