About Us

We're committed to your comfort. As a local, family-owned and operated business, we want to be able to treat you to the best possible experience when it comes to your heating, cooling, and plumbing needs. Ressler & Mateer serves commercial and residential customers throughout Harrisburg, Lancaster, Lebanon, Reading, West Chester, and York, PA. Our goal is the same as it was decades ago when it was founded - quality products, outstanding customer service, and the professional courtesy we believe you deserve.

Our Commitment

We're 100% committed to getting the job done in a way that exceeds your expectations. Ressler & Mateer invests in recruiting the finest talent and training every member of our team, giving them the tools and support they need to serve you. All of our team members, from our technicians to our office personnel, aim to make the service process simple. Whether we're scheduling your appointment, troubleshooting, ordering parts, making repairs, or installing a new HVAC system, we have your satisfaction in mind.

Our Approach

We believe that service isn't just about our ability to repair and maintain your equipment. It's also about how we take care of our customers. Did we make sure we didn't track mud through your home? Did we treat you with respect and courtesy? Did we close the door so that your pets didn't escape? When it comes to service we believe the little things add up. Our goal is to provide "white glove" service and leave your home exactly as we found it when we arrived.

Quality Products

The best service imaginable won't matter much if we don't install quality equipment. We understand that your HVAC system is a big investment and we want you to be happy with your new system. That's why we keep pace with the latest technology and work with quality HVAC equipment manufacturers. We've been an authorized Carrier dealer for years and also work with many other quality equipment partners.

Our History

Ressler & Mateer began in 1970 as a partnership between Russell Ressler Sr. and Cam Mateer. Their ambitious goal was to provide as many families in the region as possible with the best HVAC products and services - quality comfort solutions that fit both their lifestyle and their budget. Over the next decade, business grew steadily. Along with that growth, the company had earned itself a sterling reputation throughout the Lancaster County area, and the name Ressler & Mateer became synonymous with courteous, quality service.

Russ Ressler Sr. bought out Cam Mateer's interest in the company, which set the stage for it to become a true family operation. Russ Jr., Jim, Dave, and Rusty Ressler each became involved in the growing business over the years. Russell Ressler Jr. took helm of Ressler & Mateer when Russ Sr. retired in 1995.

The company remains a family operation to this day. When Russ Jr. retired in 2014, James took over as President of Ressler & Mateer, with Dave serving as the Vice President and Head of HVAC Sales. Russell Ressler III, "Rusty," serves as HVAC / Plumbing Service Manager. These three partners in the company embrace the same philosophy that drove its growth over four decades: providing the best heating, cooling, and plumbing services in the region, with quality products and professional courtesy.
