I worked with WF Smith on a bespoke project that involved procuring a custom isolation rail and lifting an existing rooftop package unit to install it. I spoke with numerous firms, both residential and commercial, and WF Smith was by far the most responsive and professional. As a result they were able to significantly improve the sound issues we were dealing with that no-one else was willing to take on.

I am very pleased with the service provided by W.F. Smith. We called for a non-urgent service call, yet they were able to send out a technician within a day. Our technician was very personable, knowledgeable and thorough. I would recommend to anyone looking for a HVAC company.

We had a wonderful experience with the WF Smith technician who came to service our AC system during a heat wave. We will definitely be calling them again for maintenance and recommending them to others. The technician was extremely knowledgable and explained all the ins and outs of the system as well as how to make it more efficient in our old Philly row home. Very valuable advice, came right on time at 8am, and felt reassured about a few issues we were having.
