Wondering what’s included in an AC maintenance appointment with WM Buffington Company? We follow a comprehensive checklist designed to identify and address small issues before they become expensive breakdowns. Our process begins with a thorough system inspection, including all electrical components, refrigerant levels, airflow efficiency, and thermostat calibration.
Next, we’ll clean your AC system inside and out—clearing dust, debris, and buildup from coils and filters to improve performance. Dirty coils alone can reduce a system’s cooling efficiency by up to 30% according to the U.S. Department of Energy (source). We’ll also lubricate moving parts, tighten electrical connections, and ensure your system is operating safely and efficiently.
Before we leave, we’ll provide you with a detailed service report and offer expert advice tailored to your system. We don’t push unnecessary services—our sales-free approach means only what you need, when you need it. Our owner David, or our service manager Larry (each with decades in the field), oversee all service quality to make sure you’re 100% satisfied.
What makes WM Buffington different from other HVAC companies? For starters, we don’t rely on salespeople—we rely on our integrity and expertise. Our owners, David and Megan, were once employees here, and they’ve built our reputation by putting people over profits. David worked in the field for 25 years before becoming an owner, so he understands what quality HVAC service truly means.
We’re proud to be BBB accredited, offer 24/7 emergency services, and provide background-checked technicians who respect your home and time. We also make it easy to afford essential maintenance with financing options, convenient scheduling, and occasional special offers on service and parts. Need a new system? We provide free estimates and offer trusted Bryant HVAC products.
But beyond our qualifications and credentials, what really sets us apart is how much we care. Megan shares, “As a woman and a consumer, I know how intimidating contractors can be. I want every customer to feel safe and respected—because credibility matters.” With WM Buffington, you’re not just another job ticket—you’re a neighbor, and we’re here to help.
Have you ever skipped a doctor’s visit, only to regret it when a small issue turned into something serious? That’s exactly how AC systems work. Regular maintenance is essential to keeping your air conditioner efficient, safe, and long-lasting. According to Energy Star, annual maintenance can help reduce your AC energy use by up to 15% (source).
Harrisburg’s warm summers, coupled with our region’s humidity, place a heavy load on cooling systems. Without regular checkups, your system may suffer from clogged filters, refrigerant leaks, and electrical problems. These issues not only increase your energy bills but can shorten your system’s lifespan—leading to costly repairs or replacements sooner than necessary.
With WM Buffington’s expert maintenance services, you’ll enjoy greater energy efficiency, lower cooling costs, and peace of mind. Our thorough inspections help prevent emergencies and ensure your home or business stays cool and comfortable throughout the season. And if we spot any potential concerns, we’ll let you know right away—with no pressure, just honest advice.
