Air Conditioning Cleaning Los Angeles
United Air Care's HVAC unit cleaning service is vital to make sure your appliances are clean, safe and running efficiently. Please note that the list below should be used as general guidelines and only performed by trained technicians. The list is not comprehensive and is intended for informational purposes only:
• Check theappliances for corrosion, water stains or leaks and clean the exterior.
• The heat exchanger should be checked and cleaned or replaced accordingly.
• Clean the gas burners and make adjustments to them as necessary
• Check all furnace wiring and make sure to take note of malfunctions or suspicious wiring.
• Check the furnace fan, including the bearings & blades, lubricate the motor, and clean the fan compartment.
• Test all safety controls before continuing operation(s).
• Inspect the furnace venting system for any obstructions or technical issues
• Inspect the gas piping, making sure to test for leaks as required
• Finalize by checking the overall operation of the furnace, including electronic air cleaners, humidifiers, etc.
Air Handler
Our technician will remove the blower for a thorough cleaning. If needed, we will disassemble the blower and wash the fan and housing. If disassembly is not required, we will air-wash the blower with a high-pressurized nozzle. After rinsing the coil, the tech will wipe down the primary drain pan and make sure that the drain is clear. Finally, we contact-vacuum all insulation and clean all hard surfaces with degreaser. After duct cleaning, an EPA registered sanitizer (usually Sporicidin) is applied and allowed to dry by running the blower for fifteen to thirty minutes.
Return Ductwork
We connect the recovery unit to the return ductwork and clean the duct with an air-forced agitator to remove contaminants. We typically hand clean the plenum attached to the air handler on a split system.
Supply Ductwork
The technician will connect the recovery unit to the supply ductwork and clean the branch runs. We start from the vent boot areas inside the ceiling, wall, or floor and use the air agitator to move debris toward the trunk. After all inside runs are clean, we move to the attic or crawl-space where we access and clean the trunk by working back toward the recovery unit.
Duct Access & Restoration
All access-openings that are cut into the ductwork are repaired and sealed by NADCA standards. Our technicians never cut accesses into flex duct. We use metal patches, screws, and masking tape to close any openings cut into metal ductwork. We also repair insulation with tape and staples and reseal the entire area with masking tape.
Restoration & Cleanup
At United Air Care Inc., we pride ourselves in being able to complete the job in your home or office and leave no evidence of our presence, other than cleaner air. The negative pressure process and the use of drop cloths creates a debree free environment, but the work may produce a small amount of dust. After reinstalling registers and moving our equipment back to the truck, we will dust and vacuum our work areas and make sure that your home is left cleaner than we found it.

Cleaning Evaporator Coils
Dirt on the evaporator coil causes two problems:
it reduces system airflow and it directly degrades
the coil's heat-transfer efficiency (which significantly
cuts cooling capacity). With a good filtration system,
you can keep your evaporator coil, and air handling
equipment cleaner for longer peroids of time.

A dirty blower wheel can greatly reduce the air flow
in your home, and cut down on the energy-efficient
rating of your system. We remove your blower
motor and take the blower housing and wheel outside
and wash it out with water and degreasing agents.

Typically, 44% of your utility bill goes for
heating and cooling. No matter what kind of
heating, ventilation, or air-conditioning system
you have in your home, you can save money
and increase comfort by properly maintaining
your system.
