Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterFast, Reliable Duct Sealing Across Menifee
We’re the crew Hollis Air Duct Cleaning sends to Menifee when a homeowner’s bedroom runs ten degrees hotter than the hallway, or when the electric bill spikes and the AC never shuts off. Our dispatch runs out of the Inland Empire office, so we’re on Menifee roads regularly, not driving down from LA or up from San Diego. That matters because duct sealing is a hands-on, attic-crawling job. You want the technician who shows up to know what 100°F attic air does to builder-grade tape, and to know that a crushed flex run off Antelope Road needs a different fix than a cracked rigid joint in Sun City. Call us at (361) 326-5060 for a free estimate. We’ll put the price in writing before any work starts, and every seal is covered by our 365-Day Done Right Promise.
Why Hollis Air Duct Cleaning Is Menifee’s Preferred Duct Sealing Company
We’ve been in this trade since 2004, and the Garrison Standard we work under hasn’t changed: arrive inside the window, price it before we touch it, finish by the book, leave the site clean. Menifee homeowners tell us that’s rarer than it should be. Our technicians are background-checked and uniformed, and you’ll know who’s coming before the van pulls up. Phones are answered by a live person, 24 hours a day, seven days a week. No voicemail loops, no “we’ll call you back Monday.” When you schedule Duct Sealing in Menifee, you’re getting a crew that treats the job like a repair, not a sales pitch.
Air Duct Sealing in Menifee
Air Duct Sealing in Menifee means finding the leaks, gaps, and failed joints in your supply and return ductwork, then sealing them with mastic and mechanical fasteners so conditioned air reaches the rooms it was meant for instead of bleeding into your attic. Most Menifee homes we see have 15 – 30% duct leakage, which is money and comfort lost every month the AC runs. A typical whole-system seal runs $850 – $1,400 for Menifee tract homes, depending on accessibility and how many runs need reconnection or replacement. Sun City ranch homes with original rigid duct often fall in the $650 – $1,100 range because the metal is durable but the old tape and mastic have dried to dust.
What We Find in the Attic
We start every job with a camera inspection. In Menifee’s newer subdivisions, we regularly see flex duct crushed flat behind the air handler or popped loose at the collar. The housing boom moved fast, and attic work got stapled and taped in place without proper support straps. We reconnect the run, support it correctly, then seal every joint with mastic rated for 200°F.
Why Leaks Cost More Than You Think
A 20% leak doesn’t mean 20% higher bills. Your system runs longer to hit thermostat setpoints, shortening compressor life and pulling attic dust through any gap it can find. In Menifee’s dry climate, that dust is fine, abrasive, and constant from March through November.
Duct Sealing Services in Menifee
Duct Sealing Services in Menifee cover the full repair: inspection, leak location, mechanical repair of disconnected or damaged runs, mastic sealing of all plenum and boot joints, and a post-seal pressure check to verify results. We use negative-air containment and HEPA filtration during the work so nothing from the attic gets pulled into your living space. For a typical 2,000-square-foot Menifee home, you’re looking at $850 – $1,400. Larger homes or those with multiple HVAC zones can run $1,600 – $2,400 if we need to access and seal two complete systems. We don’t quote per-vent or per-register. One flat price per system, agreed before we start.
The Garrison Standard on Every Job
Our Duct Sealing crews work under The Garrison Code: written price, written guarantee, background-checked technicians, and a 365-Day Done Right Promise that covers every seal we apply. If a joint opens up or a repair fails within a year, we come back and make it right at no charge, including a free second visit.
Equipment We Bring
We seal with professional-grade mastic and fiberglass mesh, not hardware-store foil tape. For containment, we run Nikro negative-air machines with HEPA filtration. Our inspection cameras are Rotobrush units that let you see what we see, register by register.

Trusted Brands We Service in Menifee
Hollis stocks filtration and sealing products from Honeywell, Aprilaire, and Guardsman, so when a Menifee home needs a new plenum boot or an upgraded return air filter base, we don’t have to order parts and come back next week. Abatement Technologies supplies our HEPA containment gear. We carry the same inventory commercial crews use because residential ductwork in Menifee faces the same heat load and dust load as light commercial jobs. That local parts stock means most seals finish in one visit, not two.
Common Duct Sealing Problems We See in Menifee Homes
- Crushed flex duct in 2010s – 2020s tract homes. The housing boom moved fast, and attic installers often stapled flex duct tight to framing or left it unsupported across rafter bays. We find runs flattened to half their diameter, choking airflow to the far bedrooms in homes off Antelope Road and McCall Boulevard.
- Foil tape failure on plenums and boots. Cheap tape and duct putty applied during original construction dries and peels in Menifee’s 100°F+ attic heat, typically within five to eight years. The leaks reopen exactly where they were sealed at build-out.
- Disconnected runs at the collar. Builder-grade flex duct in Menifee’s newer subdivisions was often pushed onto metal collars without proper draw bands or mastic. The connection loosens over time, and conditioned air pours directly into the attic.
- Cracked rigid joints in Sun City’s 1980s – 1990s ranch homes. Original metal duct and central returns have been attic-cooked for decades. Old mastic turns to powder. The joints crack, and desert dust plus attic insulation fibers enter the system continuously.

Whole-system duct sealing in Menifee typically runs $850 – $1,400 for single-system homes under 2,500 square feet. Two-story homes or properties with dual HVAC zones range $1,600 – $2,400. Sun City ranch homes with accessible rigid duct often seal for $650 – $1,100. What moves the price: how many runs need reconnection or replacement, whether the plenum itself is leaking, and attic accessibility.

FAQs About Duct Sealing in Menifee
Because builder-grade flex duct was installed fast and cheap during the housing boom. Stapled too tight, unsupported across rafters, and taped instead of mastic-sealed at collars. The dry Menifee attic heat accelerates tape failure. A camera inspection usually finds crushed runs or disconnected joints within the first ten years. Call (361) 326-5060 for a free look.
Yes. Sun City’s 1980s – 1990s ranch homes have original rigid metal duct and central returns. The metal lasts, but the old mastic and tape don’t survive decades of 100°F+ attic heat. We remove the failed sealant and reseal with modern mastic rated for temperature cycling. The repair is often simpler than replacing flex duct, but the access can be tighter.
The dry, windy Santa Ana corridor pulls fine desert dust through every gap, and the low humidity means static cling holds particles in ductwork longer. Attic heat over 100°F bakes old sealant to dust and makes new mastic cure faster, so we work methodically, joint by joint, with negative-air containment running to keep fibers out of your supply air.
We camera-inspect every run, mark leaks, reconnect or replace damaged flex, support it with proper straps, then mastic-seal every plenum and boot joint. We run negative-air HEPA containment during the work and pressure-test afterward to confirm leakage is under 5%. The whole process takes three to five hours for a typical Menifee home. You’ll see before-and-after photos of your own ducts.
Often, yes. In Menifee two-stories, we frequently find the upstairs runs crushed or leaking at the attic transition, while downstairs gets over-conditioned air. Sealing and reconnecting the upstairs runs restores balanced airflow without replacing the HVAC unit. Call (361) 326-5060 and we’ll camera-inspect to confirm whether sealing is the right fix for your layout.
