Emergency Services Available 24/7

D.E. Duffey & Sons has been helping homes and businesses weather serious storms since 1898, so you can count on us for all of your emergency heating needs. If your heat or hot water goes out, call 610-940-1400 and we'll do everything we can to restore it.

We'd like to thank you in advance for shoveling a path to your doorway and fill pipe. This allows us to safely bring you the fuel and services you need as quickly as possible. Remember: your safety is most important to us, so do not do anything that would put your health at risk.
