"WF Smith is excellent - they have done a fair bit of heating and air conditioning work for us (including replacing a system) and they are responsive, do good work, and their prices are fair. We highly recommend them."

John - 5 stars

"I have been a customer of W.F. Smith for over 20 years. They installed my first heating/a.c. system over 20 years ago. Recently, after all of this time, I realized I needed a new system. I have had a contract with them every year to service my unit twice per year. The gentleman that comes to my home every year is very knowledgeable, thorough and personable. He listens to all of my concerns and answers me very honestly. However, it was time to get a new system. With the winter coming in, I didn't want a problem in the dead of the winter and have no heat. The new heater/a.c. unit was installed on October 1st. The installers came early in the morning and worked so well together. The whole area was spotless when they finished. From Dave Smith, to maintenance, installers and staff I am so pleased. I would never consider using another company for any of my heating or air conditioning needs. They are the best."

Elaine - 5 Stars

"I highly recommend W.F. Smith. We had several HVAC providers in to analyze our needs and provide proposals. W.F. Smith was the only one who truly listened to our issues and came up with the right solution for our needs. They were on-time, thorough and professional. We are extremely pleased with the new system they installed for us. It has kept us comfortable through the winter's cold and this summer's heatwaves while lowering our utility bills. I'd say W.F. Smith is best in the Philadelphia area for HVAC services."

Sharon - 5 Stars

"W.F. Smith had maintained our 25 year old heating & a/c system for all these many years. We finally decided to install a complete new system which they just completed for us last week. They did an excellent job & the 2 service reps who installed the system were polite professional & timely. We had several contractors bid on the job and W.F. Smith was very competitive with the other bids. But after over 20 years now with them it was an easy choice to stay with W.F. Smith who we knew & trusted for so many years. We are quite pleased with their company & the newly installed equipment."

Rob - 5 stars

"W.F.Smith delivers! From the original sales process to final installation the team was exceptionally professional and detailed in their work. The sales process was very transparent without any over selling - they provided choices with pro's and con's and supported my choices. The install team was very knowledgeable and answered my numerous questions. The were personally invested in the finished product function and look - you can see the detail in even the simplest of things. They stand behind the product and the installation without a doubt. It's a quality oriented organization."
