At Groff’s Home Comfort Team, we’ve spent nearly forty years perfecting the art of emergency rescues and lasting repairs for Lititz families who refuse to compromise on comfort. We’ve seen every way heating and cooling systems fail, and more importantly, we’ve mastered every way to fix them permanently.
From furnaces that won’t fire up to air conditioners that quit mid-heatwave, from mysterious noises to skyrocketing energy bills—we diagnose problems accurately and solve them completely the first time. Your emergency becomes our priority, and your long-term comfort becomes our responsibility.
From historic downtown Lititz to the surrounding neighborhoods, our experienced team has handled every HVAC challenge imaginable. When you call Groff’s, you’re getting honest assessments, reliable repairs, and the assurance that comes from working with a family-owned business that puts your needs first.
HVAC systems work harder than most people realize, especially in Pennsylvania’s varied climate. From bitter winter cold snaps to humid summer heat waves, your heating and cooling equipment faces constant demands. Our technicians have diagnosed and repaired thousands of HVAC problems throughout Lititz, providing us with valuable insight into the issues that most frequently affect homes in our area.
When your furnace stops working during winter, every minute counts, Lancaster County winters can be unforgiving, and a malfunctioning heating system puts your family’s safety and comfort at risk.
Our technicians regularly handle:
Ignition System Failures – Modern furnaces rely on electronic ignition systems that can fail due to dirty sensors, faulty control boards, or issues with the gas supply. These problems prevent your furnace from starting, leaving you without heat when you need it most.
Thermostat Malfunctions – A faulty thermostat can cause erratic heating, constant cycling, or complete system shutdown. Sometimes, the solution is simple calibration; other times, complete replacement is necessary.
Blower Motor Issues – The blower motor circulates warm air throughout your home. When it fails, your furnace may run but produce no heat, creating uncomfortable cold spots and wasted energy.
Heat Exchanger Problems – Cracked heat exchangers pose serious safety risks by potentially allowing carbon monoxide into your living space. Our technicians prioritize these repairs to protect your family’s health and safety.
Summer heat in Lititz doesn’t ask permission before turning your home into an oven—it just happens when your air conditioning fails at precisely the wrong moment. Temperatures climbing into the 90s reveal which AC systems are truly reliable and which ones leave families sweating while waiting for repairs.
We’ve mastered the art of emergency cooling restoration because we know these common AC problems can’t wait for convenient scheduling:
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.
Compressor Failures – The compressor is your AC’s heart, and when it fails, your entire cooling system stops working. We can often repair compressor issues or recommend replacement when necessary.
Frozen Evaporator Coils – Restricted airflow or refrigerant problems can cause evaporator coils to freeze, preventing effective cooling. We identify the root cause and restore proper operation.
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 common parts to quickly restore operation.
Heat pumps battle Pennsylvania’s extreme weather year-round, and when they fail, most technicians guess—we diagnose.
Our specialists fix these complex systems permanently:
Defrost Control Problems – Failed defrost controls turn your heat pump into an ice sculpture, leaving your family cold while the system works harder and accomplishes nothing.
Reversing Valve Issues – A failed reversing valve causes your heat pump to operate in reverse, delivering hot air when you need cooling or cold air when you need heat.
Auxiliary Heat Problems – When backup heating fails during Pennsylvania’s coldest days, you’re left shivering exactly when you need warmth most desperately.
Every failed repair we’ve seen started the same way: a technician who rushed to fix what seemed obvious without investigating what was actually wrong. At Groff’s, we believe the most expensive repair is the one that doesn’t work. Our systematic diagnostic approach costs nothing extra but saves everything—your time, money, and confidence in your HVAC system.
Here’s our proven process that delivers permanent solutions:
Comprehensive System Assessment
Every service call begins with a detailed evaluation of your entire HVAC system. Our technicians don’t just look at the obvious problem—we examine components that could contribute to the issue or indicate potential future problems. This thorough assessment often reveals simple maintenance needs that prevent expensive repairs down the road.
We test electrical connections, measure airflow, check refrigerant levels, and evaluate safety controls. Many HVAC problems have multiple contributing factors, and addressing only the most obvious symptom often leads to recurring issues.
Clear, Honest Communication
Once we’ve identified the problem, we explain our findings in straightforward terms you can understand. No confusing technical jargon or pressure tactics—just honest information about your system’s condition and your repair options.
We discuss the pros and cons of different approaches, helping you make informed decisions about your home’s comfort. Whether a simple repair will solve the issue or replacement makes more sense, we provide the guidance you need without pushing unnecessary services.
Quality Repairs with Lasting Results
Our certified technicians use proven repair techniques and high-quality parts to ensure lasting results. We don’t cut corners or use inferior components that will fail prematurely. Every repair comes with our satisfaction guarantee because we stand behind our work.
When possible, we complete repairs the same day to restore your comfort quickly. For more complex issues requiring special parts, we’ll make temporary arrangements to keep you comfortable while we obtain the necessary components.
Follow-up Support and Prevention
Our relationship doesn’t end when the repair is complete. We provide maintenance recommendations to prevent future issues and extend the lifespan of your system. Regular HVAC maintenance catches small issues before they become major repairs, saving you money and avoiding unexpected breakdowns.
Your HVAC system sends warning signals before it fails completely—strange noises, weak airflow, inconsistent temperatures—but most homeowners ignore these red flags until disaster strikes at 2 AM during the worst weather of the year. We’re always ready to handle emergency repairs, but wouldn’t you prefer to avoid the emergency entirely?
Here are effective ways to prevent inconvenient breakdowns:
Air Filter Maintenance Makes a Difference
The simplest yet most important thing you can do for your HVAC system is to change air filters regularly. Dirty filters restrict airflow, forcing your system to work harder and creating conditions that lead to component failures.
Check your filter monthly and replace it when it appears dirty or clogged. Homes with pets, smokers, or family members with allergies may need more frequent filter changes. Using the correct filter size and type ensures optimal system performance.
Seasonal System Inspections
Walk around your outdoor unit seasonally to ensure it’s free from debris, vegetation, and obstructions. Keep the area around your outdoor unit clear to maintain proper airflow. Listen for unusual noises when your system operates—grinding, squealing, or banging sounds often indicate developing problems.
Indoor units also benefit from visual inspection. Look for water leaks, unusual odors, or signs of component wear. Early detection of these issues can prevent more expensive repairs in the future.
Professional Maintenance Partnerships
Annual professional maintenance by qualified technicians catches problems you might miss and keeps your system operating efficiently. During maintenance visits, technicians clean components, lubricate moving parts, check refrigerant levels, and test safety controls to ensure optimal performance.
Regular maintenance typically pays for itself through improved efficiency and fewer repair needs. Well-maintained HVAC systems last longer, operate more quietly, and provide more consistent comfort throughout your home.
Understanding Your System’s Needs
Different HVAC systems have unique maintenance requirements. Heat pumps need attention to defrost controls and reversing valves. Gas furnaces require combustion system inspection and flue cleaning. Central air systems benefit from coil cleaning and refrigerant level checks.
Learning about your specific system helps you recognize potential problems and communicate effectively with service technicians. Keep your system’s manual handy and note the manufacturer’s recommended maintenance schedule.
Every HVAC contractor promises great service until you actually need it during an emergency. Then you discover who really knows their trade and who’s just hoping for the best with your family’s comfort. At Groff’s, we’ve spent nearly four decades proving our promises with performance that works when everything else fails.

How do I know if my older HVAC system should be repaired or replaced?
Several factors help determine whether repair or replacement makes more sense for your situation. If your system is over 15 years old and requires expensive repairs (typically over $1,500), replacement often provides better long-term value. Frequent breakdowns, rising energy bills, and difficulty maintaining comfortable temperatures also indicate it may be time for a new system. Our technicians provide honest assessments and help you weigh repair costs against the benefits of newer, more efficient equipment. We never pressure customers into unnecessary replacements.
Do you service all brands of HVAC equipment, including older or uncommon manufacturers?
Yes, our technicians are trained to service virtually all major HVAC brands, and many older manufacturers are no longer in business. We maintain relationships with parts suppliers who can source components for older systems, though availability and cost can vary for discontinued models. During our diagnostic process, we’ll determine parts availability and provide realistic expectations about the feasibility of repairing older equipment. Our diverse experience with various manufacturers enables us to find creative solutions for challenging repair situations.
What warranty do you provide on HVAC repairs, and what does it cover?
We stand behind our work with comprehensive warranties that cover both parts and labor. Most repairs include a one-year warranty on our workmanship, as well as manufacturer warranties on replacement parts, which vary by component. Our warranty covers the specific repair performed. If the same problem occurs due to our work, we’ll return to fix it at no additional charge. We provide clear warranty documentation explaining what’s covered and for how long, so you know exactly what protection you have after we complete your repair.
