A full HVAC system cleaning goes far beyond surface duct cleaning. It addresses the heart of your system: the evaporator coils, the blower wheel, the air handler interior, and the drain pan. Most Longview homes see a 15–20% improvement in HVAC efficiency after a full system cleaning.
What a Full HVAC Cleaning Covers
We clean the entire air-handling assembly: supply and return ducts, evaporator coil, blower wheel and motor housing, drain pan, filter rack, UV light housings, and return air plenum.
These are the places where dirt does the most damage to performance and equipment over time. Most 'duct cleaning' services skip them entirely.
Why East Texas Humidity Makes This Critical
Longview summers regularly hit 80–90% humidity. Dust mixes with condensation on the coil surface, forms a sticky paste, and over time becomes a thick insulating layer that prevents proper heat transfer.
The result: your system runs longer to hit the same temperature, humidity climbs, mold grows on the wet coil surface, and your blower motor burns out earlier than it should.
Real Energy Savings
DOE and ASHRAE both document significant efficiency losses from dirty coils. For a Longview home spending $300/month on summer cooling, a 15–20% efficiency gain pays for the entire HVAC cleaning in a single summer.
Our Process
We start with a full inspection including current static pressure and amp draw readings. We clean the supply and return ducts using the standard negative-pressure method, then open the air handler and clean the coil with EPA-registered foaming coil cleaner, brush out the blower wheel, sanitize the drain pan, and verify proper condensate flow.

Frequently Asked Questions
How is this different from regular duct cleaning?+
Standard duct cleaning addresses the ductwork itself. Full HVAC cleaning includes the equipment — coils, blower, drain pan, plenum.
Will this void my equipment warranty?+
No. Cleaning is standard maintenance and most manufacturers actually require periodic cleaning to maintain warranty coverage.
How often should I have full HVAC cleaning done?+
Every 3–5 years for most East Texas homes, more often if you have pets, allergies, or high humidity.
Do I need this if I just had a regular AC tune-up?+
Yes — AC tune-ups check refrigerant and electrical components. Full HVAC cleaning physically removes the dust and biofilm from the coil and blower that tune-ups don't address.
Will this fix my high humidity problem?+
Often, yes. A clogged evaporator coil can't dehumidify properly. Cleaning the coil restores latent capacity and frequently solves indoor humidity complaints.
