Honest duct work and air quality in Wilmington

I'm about 14 minutes from Wilmington when traffic cooperates.

Most duct work and air quality calls I run in Wilmington share a few things in common: older single-family bungalows from the 1920s–1950s, lots of duplexes, with the kinds of HVAC quirks that come from that vintage. Leaky ducts waste 20-30% of every dollar you pay to heat or cool your home. In a 1965 Torrance ranch with original ducting, that's not an estimate — that's the floor.

Things I check on every Wilmington duct work and air quality call:

  • salt + diesel particulate + refinery emissions + summer heat — the worst combination for outdoor coil longevity in the South Bay.
  • Housing stock here is older single-family bungalows from the 1920s–1950s, lots of duplexes, smaller footprints, original ducting and original everything in many homes.
  • Common duct work and air quality jobs in Wilmington: premature compressor failures, badly corroded coils, dust-clogged blowers, plus the occasional wall heater that hasn't been touched since the 1970s.

The problems I usually find on Wilmington duct work and air quality calls

  • Undersized supply. 1960s ducts were sized for 2-ton systems; you've got a 4-ton condenser pushing through them. Hello, low static pressure.
  • Tape-failure leaks. old cloth duct tape disintegrates in attic heat. Aeroseal or mastic is the fix, not new tape.
  • Disconnected returns. I find at least one fully disconnected return register every month — the system has been pulling attic air for years.

Here's what actually happens when I roll into Wilmington for a duct work and air quality job:

  1. You text or call. I read it on my phone, between jobs.
  2. I confirm a 2-hour arrival window in Wilmington.
  3. On-site, I diagnose the system and write a flat-rate quote — no work starts until you sign off.
  4. I improve it, clean up like I wasn't there, and the warranty is in writing.

Pricing: $129 duct pressure test (waived if you proceed with sealing). 5-year warranty on Aeroseal sealing. Sealing: half-day to full-day. IAQ install: 2–4 hours.
