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.
Fast, Reliable HVAC Cleaning Across Mount Lebanon
HVAC cleaning in Mount Lebanon, PA typically runs $420-$680 for a full-system clean on a 1920s-1950s home, depending on the number of runs and what the camera finds once we open the ductwork. We schedule Mount Lebanon jobs Monday through Saturday and most homes are completed in 4 to 7 hours. This is not a quick vacuum pass. Older Mount Lebanon houses carry decades of accumulated debris that standard equipment simply won’t remove without proper source-removal agitation and professional negative-pressure extraction. Call (806) 606-6902 and we’ll give you a written price before any panel comes off.
Why CleanRun Air Duct Cleaning Is Mount Lebanon’s Preferred HVAC Cleaning Company
Homes in Mount Lebanon are not like newer construction in the southern or western suburbs. The ductwork here was built for coal-fired gravity heat, then converted to gas forced-air decades ago, and most of it has never been professionally opened. Our crews understand what that means in practical terms: original sheet-metal trunks with separated seams, sagging branch lines, and a fine black coal-dust layer bonded to the interior walls. We do not treat Mount Lebanon as a generic job site. We treat it as one of the most technically demanding housing stocks in the Pittsburgh region, and our process is built around that reality.
CleanRun has been in business since 2013, and every Mount Lebanon job gets the same standard: a written price before work starts, a camera inspection at the start, and a documented photo record of every duct run before and after. The 365-Day Done Right Promise is in writing on the job record, not a verbal reassurance. Tomas Reyes, who leads our Pittsburgh-area operations, insists on one rule for every crew: if you cannot photograph it, you did not do it.
Our HVAC Cleaning team arrives in uniformed, background-checked vehicles, and every technician names themselves before entering your home. We publish our license information openly. We carry professional-grade equipment from Rotobrush, Nikro, and Guardsman, and we show customers what each tool is doing while the job runs. Mount Lebanon homeowners tend to research before they call. We give them something to research.
Our HVAC Cleaning Services in Mount Lebanon

Evaporator Coil Cleaning
The evaporator coil sits inside the air handler and is the surface where refrigerant absorbs heat from your home’s air. On Mount Lebanon’s older systems, this coil is frequently coated with a sticky film of dust and pet hair that solidifies over years of heating seasons. A dirty evaporator coil forces the blower to work harder against reduced airflow, raising run times and utility costs. We clean the coil with manufacturer-compliant foaming cleaners and soft-bristle agitation, then photograph the result. In Mount Lebanon, this service typically runs $180-$260 as part of a full system clean, or $220-$320 as a standalone job, depending on accessibility.

Blower Cleaning
The blower wheel in a Mount Lebanon furnace often carries a dense mat of compacted dust on each blade, especially in homes that ran without modern filtration for decades. That buildup unbalances the wheel, stresses the motor bearings, and reduces the volume of air moving through the house. We pull the blower assembly, clean each blade with non-damaging agitation tools, vacuum the housing, and inspect the motor capacitor while we’re there. Blower cleaning in Mount Lebanon homes with original 1950s furnaces typically runs $150-$230, and it is one of the highest-value cleaning steps on older systems where airflow has dropped gradually over years.

Condenser Cleaning
The outdoor condenser coil collects cottonwood seed, grass clippings, and the fine particulate that comes with living on a plateau above the Monongahela valley. Mount Lebanon’s elevated position gets persistent wind flow that drives more debris into the outdoor unit than lower-lying areas. We clean the condenser with a coil-safe detergent and low-pressure rinse, straighten bent fins, and verify the refrigerant line insulation is intact. Expect $130-$190 for a standard residential condenser clean in Mount Lebanon.

Air Handler Cleaning
The air handler enclosure itself is often the dirtiest component in a Mount Lebanon system, particularly in full basements where dust and humidity settle year-round. The inside of the cabinet, the condensate pan, and the return-side plenum collect a grime that standard filter changes never address. We clean the interior surfaces, treat the condensate pan to prevent biological growth, and sanitize the plenum before reinstalling the blower. Air handler cleaning runs $200-$300 for the typical Mount Lebanon colonial or Tudor-style home, and we typically recommend it alongside a full duct cleaning because cleaning the ducts without cleaning the air handler simply pulls new contamination into the fresh ductwork within weeks.

AfterTrusted Brands We Service in Mount Lebanon
We work on systems from every major furnace and air handler brand found in Mount Lebanon basements: Carrier, Trane, Lennox, Rheem, Goodman, York, and older units from the 1950s through 1990s that have long since outlived their original documentation. We stock common replacement filters, blower components, and coil-cleaning chemistry calibrated for the brands we see most often in this housing stock. If you have an old gravity-furnace conversion with an unusual duct configuration, we are not going to scratch our heads and improvise – we have been through enough Mount Lebanon basements to know what that octopus trunk looks like before we even open the cleanout. We use Guardsman coil treatments and Honeywell filtration products where specified by the system design.
Common HVAC Cleaning Problems We See in Mount Lebanon Homes

- Coal-dust-bonded duct walls. The original octopus-furnace trunks along Washington Road retain a fine black residue that hardened with humidity over the decades. A routine vacuum pass lifts the surface layer and leaves the bonded contamination intact, which is why we run HEPA-filtered agitation tools for hours, not minutes.
- Separated sheet-metal seams. The original ductwork in 1920s and 1930s homes was assembled with slip joints and lap seams, not the sealed, mastic-taped connections required by modern code. Fifty or sixty years of thermal expansion and contraction opens those seams, and we find basement duct runs leaking conditioned air into the crawlspace while pulling musty air from wall cavities into the return side. Sealing these runs is often the real fix, not just cleaning them.
- Deteriorated insulation liner. Some original trunk lines were lined with a fiber or paper-based insulation that has broken down over 70 to 90 years. Aggressive agitation by a technician who does not recognize 1930s construction can flake this liner into the airstream. We camera-inspect every run before we start and switch to a gentler cleaning method when we spot fragile liner material.
- Crushed or disconnected branch runs. In Mount Lebanon basements where decades of storage, plumbing work, and remodels have taken place, branch runs to first-floor registers are frequently crushed by shelving or disconnected entirely. We find runs that have been blowing conditioned air into the basement for years, not the living room. Camera documentation shows the homeowner exactly what we found, and sealing those failures is included in the written scope when required.
Pricing for HVAC Cleaning in Mount Lebanon, PA
A complete HVAC cleaning on a typical Mount Lebanon two-story colonial or Tudor, including air handler cleaning, evaporator coil cleaning, blower cleaning, and full duct cleaning, runs $420-$680. If your system includes a converted gravity-furnace trunk with heavy coal-dust residue, expect the upper end of that range because of the extra agitation time and the camera inspection required before we call the job complete. Sealing disconnected runs adds $120-$260 depending on how many joints have separated. Condenser cleaning is $130-$190 on its own. Every job starts with a written price before a single panel is removed, under Haven Standard Clause 1. No one from CleanRun will ever ask you to approve additional work verbally without a written change to the scope. Call (806) 606-6902 for a free estimate.

FAQs - HVAC Cleaning in Mount Lebanon

Yes, but only with source-removal agitation and HEPA-filtered negative pressure, not with a standard vacuum pass. The coal residue on the interior walls of an 80-year-old trunk line has bonded to the sheet metal over decades of humidity cycling. We use Rotobrush agitation tools to break that layer loose, then run continuous negative pressure to capture the debris as it releases. Off Washington Road near the trolley corridor, our crew opened a cleanout on a 1930s colonial and found the main trunk line coated in exactly this residue, undisturbed since the home’s original octopus furnace was converted. We ran negative pressure with HEPA filtration for three hours to break the layered debris loose, then camera-inspected the runs and sealed two disconnected joints in the basement where the old sheet metal had separated, restoring airflow to the upstairs bedrooms. That is the standard a Mount Lebanon job requires. Call (806) 606-6902 for a written quote on your specific duct configuration.
The most common signs are uneven heating between rooms, a musty smell coming from returns, and visible dust accumulating on registers in rooms you rarely use. Disconnected runs leak conditioned air into the basement and pull unfiltered air from wall cavities and crawlspaces. The only way to confirm it is with a camera inspection. We include a pre-cleaning camera walkthrough on every Mount Lebanon job, and we show you what the camera sees before we recommend sealing work. If we find disconnected runs, the written scope is updated with a price for sealing them before any work continues.
Because the dust is already inside the ductwork, downstream of the filter, and much of it has been there since the house burned coal. A high-MERV filter catches what enters the return side from the living space. It does nothing for the coal-dust layer bonded to the interior of the trunk line, or the debris sitting in branch runs that have been disconnected for decades. In a converted gravity-furnace system, the filter is also often in a different location than where the air actually leaks, so the filter sees only a fraction of the air moving through the duct system. Cleaning the ducts and sealing the leaks is the only fix that addresses the root source.
Agentle, low-agitation cleaning with camera monitoring before and during the work. We do not run aggressive mechanical brushes through older lined ducts because the liner material has often broken down after 70 to 90 years of thermal cycling. Instead, we choose a low-torque agitation method and check the camera feed as we clean, watching for liner flaking. If we see the liner beginning to release, we stop and discuss replacement options with you before continuing. The safest way is to know what you are cleaning before you start. That is why we camera every run first.
No. A standard duct cleaning, which most companies sell as a fixed-fee vacuum service, does not address the sealed coal-dust layer, the separated seams, or the disconnected branch runs that are common in Mount Lebanon’s pre-1950s housing near the trolley corridor. These homes need component-level cleaning, source removal at the trunk level, and sealing work that restores the system to functional condition. A standard vacuum pass over a gravity-furnace conversion leaves the original contamination bonded to the metal and does nothing for the leaking joints. We price that work honestly on the first visit and document all of it with before-and-after photos. Call (806) 606-6902 and we’ll put a written number in front of you.
