Timothy Off Difference

Locally Owned Heating and Cooling Company

We are a locally owned and operated company, so we’re very familiar with West Chester, Pennsylvania, and its many surrounding areas. Unlike larger HVAC companies, we like to think of ourselves as your neighbors, and we’re here when you need us.

Years of Experience

With years of experience in commercial and residential HVAC and plumbing sales, service, and installation, we’re confident we can help you with any heating, cooling, or plumbing problem you may have. We’ve seen it all, so we can quickly diagnose what’s wrong and recommend the best way to fix it.

Quality Products

We know that high-quality equipment lasts longer, costs less to maintain and operate, and looks great. That’s why we carry only top-of-the-line products we’re sure will satisfy any homeowner or business.

Attention to Detail

Our reputation for clean work, friendly service, and fair prices is what makes 99 percent of our customers tell us they would recommend us to their friends, family, and coworkers. All of the certifications we have received, such as being a Trane-qualified dealer, ensure we offer the best service.


All of our technicians hold several reputable certifications such as NATE (North American Technician Excellence) certification—the highest level of certification in the HVAC industry—the REPA certification, certification for Trane HVAC services, and certifications from various environmental agencies including IGSHPA (International Ground Source Heat Pump Association). We are proud to be a Mitsubishi Electric Diamond Contractor. We also have a master plumber and oil-certified technicians on staff.

If you’ve ever had heating problems during the winter or cooling problems during the summer, we know how frustrating they can be. That’s why we’re on call every day of the year, 24 hours a day. No matter what problem you may have, just give us a call and we’ll help you fix it.
