Do you cover all of Marrero?

Yes, all of ZIP 70072, along with neighboring Harvey and Westwego.

Is it worth sealing old ducts instead of replacing them?

Often, yes. If the runs are intact and sized right, sealing and insulating them costs far less than a new duct system.

My heat strips smell like burning. Is that normal?

A dusty smell on the first cold day is normal. A sharp or lingering smell is not; turn the heat off and call.

Should I switch from strip heat to a heat pump?

If your AC is due for replacement, usually yes. A heat pump heats most days for much less, with the strips kept as backup.

Can you tell if my ducts are leaking?

Yes. Weak grilles, dust lines, rooms that never cool and high bills are the signs, and a trace through the attic confirms it.

Short answer

We serve Marrero, ZIP 70072, on the West Bank between Harvey and Westwego. Many homes here date from the 1960s and 1970s, so leaky original ducts, worn heat strips and aging air handlers are common, along with summer AC repairs. Sealing the ducts and switching strip heat to a heat pump can lower bills. The line is answered 24/7.

Original ducts and strip heat in 1960s and 1970s homes

Marrero shares the West Bank's building history: most suburban housing here went up in the 1960s and 1970s. Duct systems from that era were often joined with cloth tape and wrapped with thin insulation, and decades of attic heat have loosened joints and flattened runs. Before anyone talks about a new system, we trace the ducts, seal the joints with mastic and replace the runs that are past saving.

Many older West Bank homes also heat with electric strips in the air handler, which works but costs a lot on cold days. When a strip burns out, or the AC is due for replacement anyway, a heat pump can take over most of the heating and leave the strips as backup. We size it from a load calculation and price it beside a like-for-like replacement.
