What Determines the Time Needed for AC Cleaning?
The time it takes to clean your air conditioner depends on several key factors. These range from the type of AC unit you have to how dirty it is. Here’s what usually matters most:
- Type of AC unit (split, window, central, ducted, portable, or cassette ACs)
- Number of indoor and outdoor units
- Level of dust and dirt buildup, including pet hair or construction dust
- Accessibility and placement of units (e.g., rooftop, balcony, above false ceilings)
- Whether a standard or deep clean is performed
- Age and condition of the AC (older units may need more careful handling)
- Availability of water supply and drainage for rinsing components
Typical AC Cleaning Durations
Most standard AC cleaning jobs take between 45 minutes and 2 hours per unit. Central or ducted systems often need more time—sometimes up to 4 hours—especially if ducts are involved. For example, a split AC in a Dubai apartment might take just under an hour for a regular service, while a villa with multiple units and ducts could require a half-day session.
If you add ac duct cleaning to your service, expect an extra 2–4 hours, depending on your home’s size and layout. In larger villas or commercial spaces, cleaning all vents and ducts can extend the total service time significantly.
In shared buildings or apartments, arranging access to service balconies or rooftops can also add waiting time, so it’s a smart idea to notify your building management in advance.
Comparison Table: Cleaning Times by AC Type
| AC Type | Standard Cleaning | Deep Cleaning |
|---|---|---|
| Window Unit | 30–45 min | 60–90 min |
| Split AC (per unit) | 45–90 min | 1.5–2.5 hrs |
| Central/Ducted | 2–3 hrs | 3–5 hrs |
| With Duct Cleaning | +2–4 hrs | +3–6 hrs |
For households with multiple AC types (e.g., split units in bedrooms and central AC in living areas), cleaning times can be combined. In the UAE, it’s common to pair AC cleaning with other seasonal maintenance, like water tank or exhaust fan cleaning, to maximize technician visits and minimize disruption.
What’s Included in a Professional AC Cleaning?
A standard AC cleaning usually covers filter washing, coil cleaning, drain pan and pipe flushing, and a check for visible mold. Deep cleaning may involve disassembling the unit, chemical washing, and thorough duct cleaning. Some providers also sanitize vents and deodorize the system for fresher air.
- Filter and coil cleaning (removing dust, pollen, and allergens)
- Drain line flushing to prevent leaks and odors
- Fan and blower dust removal for quieter operation
- Basic electrical checks to ensure safe startup
- Inspection for refrigerant leaks or unusual noises
- Sanitization of vents and grills (if requested)
- Reassembly and function testing after cleaning
Some services offer optional add-ons, like antibacterial treatments or filter replacements, which can add 10–20 minutes per unit. If you’re sensitive to dust or have allergies, ask about these extras for better indoor air quality.
Key Factors That Can Slow Down AC Cleaning
Heavy Dirt and Neglect
If your AC hasn’t been cleaned in over a year, expect the process to take longer. Thick dust, mold, or clogged drains require extra effort and possibly special tools. For example, units in coastal regions like Abu Dhabi may accumulate salt and sand, needing more intensive cleaning.
Challenging Locations
Units installed in tight spaces, on high ceilings, or outdoors in difficult-to-reach spots will slow things down. Technicians may need extra time for safe access. Rooftop condensers in summer may require cooling breaks, especially in the UAE’s extreme heat.
Weather and Regional Factors
In the UAE, sandstorms or high humidity can clog filters and coils faster, so more frequent or intensive cleaning is needed in desert or coastal areas. If you live near construction sites, expect more dust and longer cleaning times.
DIY vs. Professional AC Cleaning: What’s Faster?
DIY filter cleaning is quick—often under 30 minutes. But a full AC service, especially involving coils or ducts, is usually faster and more thorough with a professional team like fixpro. Pros bring specialized tools and can spot hidden issues. Attempting deep cleaning without experience can lead to missed dirt or accidental damage, which may require costly repairs.
- DIY: Good for simple filter rinsing and wiping accessible grills
- Professional: Required for deep cleaning, mold, or persistent odors
- DIY: May take longer if you lack proper tools or need to watch tutorials
- Professional: Can address multiple units or issues in one visit
If you’re cleaning your own AC, always turn off the power, wear a mask, and use only recommended cleaning solutions. For anything beyond basic filter maintenance, booking a pro is safer and more time-efficient.
Tips to Make AC Cleaning Quicker and Smoother
- Clear the area around your AC units before technicians arrive—move furniture, curtains, and décor
- Schedule regular cleanings to prevent heavy buildup and reduce future service time
- Let the team know if you have pets or allergies so they can use appropriate cleaning agents
- Provide easy access to water and power outlets for technician equipment
- Combine services, like kitchen exhaust cleaning, for convenience and efficiency
- Inform building security or management if access to rooftops or service areas is needed
- Keep a maintenance log with last service dates and any previous issues
- Ensure someone is home to answer questions or provide access to all rooms
For best results, pair AC cleaning with a fresh loaf of bread or light snacks for your family—after all, you’ll want to enjoy the cool, clean air in comfort! If you’re hosting guests, schedule cleaning a few days before for the freshest environment.
FAQs About AC Cleaning Time and Process
How long does it take to clean a split AC unit?
Usually 45–90 minutes for one indoor unit.
Does AC duct cleaning add much time?
Yes, it often adds 2–4 hours, depending on your ductwork.
Can I use my AC right after cleaning?
Yes, once the technician finishes and the unit is dry, it’s safe.
Is it faster to clean multiple AC units at once?
Yes, teams can often clean several units in parallel.
What slows down AC cleaning the most?
Heavy dirt, mold, or hard-to-reach locations are the main delays.
Does regular HVAC maintenance reduce cleaning time?
Absolutely—routine HVAC maintenance keeps cleaning sessions shorter.
What should I do if my AC still smells after cleaning?
Persistent odors may indicate mold in hidden areas or dirty ducts. Ask your provider about deep sanitization, duct cleaning, or installing odor-absorbing filters.
Can regional factors affect cleaning time?
Yes, areas with more dust (like Sharjah or Al Ain) or high humidity (like coastal Dubai) often require more frequent and intensive cleaning, which can take longer.
What are common troubleshooting tips if my AC is still weak after cleaning?
Check if the filters and vents are fully dry and properly reinstalled. Ensure the thermostat is set correctly. If airflow is still weak, there could be a deeper blockage or mechanical issue—contact your technician for a follow-up.
