"Got bids from three companies for a full system swap. DC was the only one who did a real Manual J load calc and the only one with all-in pricing. Beat the others by $1,800 on a Trane XV20i."

HVAC duct and vent cleaning in Palmdale, CA matters more than most homeowners expect, because hot dry summers, windy winters, and a 40°F day-to-night swing pushes fine desert dust into every return and supply run. DC Air and Heating cleans duct systems throughout Palmdale, Antelope Valley using negative-pressure equipment and agitation — not a shop vac at the register — and we photograph the interior before and after so you can see the result.
The service includes sealing off supply and return registers, connecting a HEPA-filtered negative air machine to the trunk, agitating each branch with rotating brushes or compressed-air whips, cleaning the return plenum and blower compartment, wiping registers and grilles, inspecting for disconnected or crushed runs, and replacing the filter with the correct size and MERV rating for your blower. Any leaks or damage we find are documented with photos and quoted separately.
In Palmdale, the dust load is not theoretical. Homes near Rancho Vista and Anaverde routinely show two-story homes that cool unevenly and refrigerant leaks at flare fittings, and attic-mounted duct systems across 93550, 93551, 93552, 93591 pull outside air through every unsealed joint. Cleaning without sealing simply reloads the system, so we always inspect for leakage and tell you honestly if sealing — not cleaning — is the real fix.
Whole-home duct and vent cleaning in Palmdale, CA typically runs $495–$1,250 depending on the number of registers, system count, and attic access. Dryer vent cleaning can be added on the same visit. If our inspection shows the ducts are clean and the problem is filtration or leakage, we will say so and quote the work that actually helps rather than selling a cleaning you do not need.
Palmdale sits roughly 300 feet higher than Lancaster, and that shows up in winter: heating runtime here is measurably longer, which is why furnace-side failures make up more of our Palmdale calls than our Lancaster ones. The west-side neighborhoods off Rancho Vista and Anaverde are heavy on two-story 1990s and 2000s tract homes with a single zone serving both floors — the upstairs runs 6–8 degrees warmer in August unless the return path is corrected. Permits go through the City of Palmdale, and replacements trigger Title 24 duct-leakage testing. East Palmdale addresses off Palmdale Boulevard add roughly ten minutes to our drive.
We are a locally owned Los Angeles County HVAC contractor headquartered at 5345 West Avenue M8 in Lancaster — about 8–16 miles from Palmdale, CA, or 20–40 minutes in normal traffic.

Every three to five years for most Palmdale homes, sooner after a remodel, a rodent intrusion, or a wildfire smoke event. Given hot dry summers, windy winters, and a 40°F day-to-night swing, homes with pets and one-inch filters land at the shorter end of that range. See HVAC Duct & Vent Repair in Palmdale, CA.
It helps when the ducts are genuinely fouled. Often the larger win in Palmdale is sealing return leaks and upgrading to a properly sized MERV-13 media cabinet so the system stops pulling attic dust in the first place.
