Seffner plumbing & AC
Short answer: Alvarez Plumbing & AC serves all of Seffner, from Lake Weeks and Mango to Kingsway, Lake Shore Ranch and the newer communities off I-4, 24/7. We're a family-owned Tampa company since 1976, with 4.8 stars from more than 2,600 Google reviews. Seffner has older homes on wells and septic right next to brand-new subdivisions, and we service both.

Local landmark
Seffner is one of the older communities in east Hillsborough. It was once called Simmon's Hammock and took its name from Frederick P. Seffner, its first postmaster. The post office, first school and first store all opened in 1884. During Tampa's 1887–88 yellow fever epidemic, families came here to escape it, and by 1925 Seffner was the fourth-largest town in Hillsborough County.
Locals know Lake Weeks, a 58-acre lake on the southeast side lined with Spanish moss and popular for fishing, and Seffner-Mango Park and library. I-4 runs along the north edge of town, and Martin Luther King Jr. Boulevard along the south.
Seffner's homes come in two groups. The older core has a typical build year in the mid-1970s, and about a quarter of homes in the 33584 ZIP date from the 1960s and 70s. Those homes may have aging galvanized or cast iron pipe, and some are on wells and septic. More than half of homes were built in 2000 or later, and their original AC systems and water heaters are now reaching replacement age. Seffner is also in the part of Hillsborough known for sinkholes, where shifting ground can stress pipes under a slab.
