# PC Cleaning Service Dhaka — How to Clean Your Computer at Home (2026 Guide)

**A professional PC cleaning service in Dhaka costs BDT 1,500–3,000 for a home visit. Most desktops need deep cleaning every 6–12 months — faster in dusty areas like Mirpur, Mohammadpur, and Old Dhaka. Overheating due to dust is the single most common cause of sudden PC shutdowns in Bangladesh's hot, humid climate.**

Dust is the silent killer of computers in Dhaka. Between April and October, temperatures routinely exceed 35°C — and a dust-clogged heatsink can push your CPU above 90°C, triggering thermal shutdowns or permanent damage. This guide explains when you can clean your PC yourself, how to do it safely, and when to call a professional cleaning service.

For a confirmed quote on professional PC cleaning in Dhaka, WhatsApp **01712-644590** — BAYAS responds within 30 minutes and provides same-day home service across all 36 Dhaka zones.

## Why Does a PC Get So Dirty in Dhaka?

Dhaka's air quality and climate create near-ideal conditions for PC dust accumulation:

- **High particulate count** — construction dust, vehicle exhaust, and seasonal sand storms coat every horizontal surface, including PC air intakes.
- **Humidity cycling** — 80–95% relative humidity in monsoon season causes dust to clump and stick to heatsink fins rather than blow through.
- **Fan-forced airflow** — desktop and laptop cooling fans actively pull air (and debris) through the case all day.
- **Power cuts and UPS cycling** — load-shedding means PCs start and stop frequently; each startup pulls a fresh gulp of dusty air.

A desktop PC in a typical Dhaka apartment accumulates enough dust in 6 months to reduce airflow by 40–60%, raising CPU temperatures by 15–25°C. In summer, that difference can mean the gap between a stable 75°C and a shutdown-triggering 95°C.

## What Are the Warning Signs Your PC Needs Cleaning?

| Warning Sign | What It Means | Risk Level |
|---|---|---|
| Fan running louder or constantly at max | Heatsink clogged — fan compensating | High |
| PC shuts down after 20–30 minutes of use | Thermal shutdown protection triggered | High |
| CPU temperature above 80°C at idle | Dust insulating the heatsink fins | High |
| Blue screen (BSOD) after recent hot season | Thermal stress on CPU/RAM solder joints | High |
| Visible grey lint on case vents | Active dust ingestion in progress | Medium |
| PC takes longer than usual to cool after shutdown | Poor internal airflow | Medium |
| Fan noise has changed pitch or rhythm | Dust on fan blades causing imbalance | Medium |
| Keyboard keys sticky or sluggish (laptop) | Debris under keys | Low–Medium |

If you see two or more of these signs, your PC needs cleaning within the next 1–2 weeks. Continuing to run a dust-clogged system risks permanent damage to the CPU, GPU, or motherboard from repeated thermal cycling.

## How to Clean Your PC at Home in Dhaka — Step-by-Step

### What You Need Before Starting

- Can of compressed air (available at Agargaon IDB Bhaban, Multiplan Center, or most computer shops — approximately BDT 400–800)
- Soft lint-free microfibre cloth
- Isopropyl alcohol (70% or above) — BDT 150–300 at pharmacies
- Phillips-head screwdriver (if opening desktop case)
- Antistatic wrist strap (optional but recommended — BDT 200–400)

### Desktop PC Cleaning — 7 Steps

1. **Shut down and unplug** — power off completely, not sleep or hibernate. Unplug the power cable from the wall.
2. **Move to an open area** — carry the PC to a balcony, corridor, or space where dust can blow away rather than settle back inside.
3. **Ground yourself** — touch a grounded metal object or use an antistatic strap to discharge static before opening the case.
4. **Open the side panel** — usually two thumb screws on the back. Lay the PC on its side on a clean surface.
5. **Blow dust from vents, heatsinks, and fans** — hold compressed-air cans upright, use short bursts (2–3 seconds), and keep the nozzle 10–15 cm from components. Hold fans still with a pen while blowing — spinning fans from compressed air can damage bearings.
6. **Clean the case vents from the outside** — use a microfibre cloth dampened slightly with isopropyl alcohol on exterior metal surfaces and fan grills.
7. **Reassemble and test** — replace the side panel, reconnect power, boot, and open a temperature monitor (HWMonitor or HWInfo64 — both free) to verify CPU and GPU temps have dropped.

### What NOT to Do When Cleaning a PC at Home

> **Never use a household vacuum cleaner** directly on PC components — it generates static electricity that can instantly kill a motherboard, GPU, or SSD. Use compressed air only for internal components.

- Do not spray water or household cleaning sprays inside the case
- Do not use tissues or paper towels (they leave fibres and generate static)
- Do not hold compressed-air cans at an angle — liquid propellant can spray onto components
- Do not clean thermal paste off the CPU without replacing it with new compound

### Laptop Cleaning — Key Differences

Laptops are more difficult to clean at home without disassembly:

| Laptop Cleaning Method | What It Achieves | Limitation |
|---|---|---|
| Compressed air through vents (without opening) | Dislodges loose surface dust | Pushes dust deeper if heavily clogged |
| Full disassembly + heatsink removal | Complete cleaning + thermal repaste | Requires tools and skill; voids warranty if done incorrectly |
| Keyboard compressed-air clean | Removes key debris | Doesn't address internal cooling |
| Professional BAYAS service | Full internal clean + repaste + test | Best result; BDT 1,500–3,000 at your home |

For heavily clogged laptops (fan constantly at max, frequent shutdown), disassembly is required — the bottom panel, fan, and heatsink need to be removed, cleaned, and repasted. BAYAS technicians carry thermal paste and do this at your home in 45–90 minutes.

## What Does a Professional PC Cleaning Service in Dhaka Cost?

| PC Cleaning Service | BAYAS Price (BDT) | What Is Included |
|---|---|---|
| Desktop deep clean (home visit) | 1,500 – 2,500 | Case interior, heatsink, fans, cable tidy — thermal repaste included |
| Laptop deep clean (home visit) | 1,800 – 3,000 | Full disassembly, heatsink clean, fan service, thermal repaste, reassembly + test |
| Office PC batch clean (per unit, 3+) | 1,200 – 1,800 per PC | Same service, bulk visit |
| Thermal repaste only (no full clean) | 800 – 1,500 | CPU/GPU compound replacement, temperature test before + after |
| Home visit + diagnostic only | 700 – 1,200 | Credited toward cleaning if you proceed |

> **Price note:** These are BAYAS 2026 rates. All prices include the home-visit fee, compressed air, and thermal compound. For offices with 3+ units, a single visit covers all machines — call **01712-644590** for a bulk quote.

After a professional clean, most customers see CPU idle temperatures drop by 15–30°C. A thermal repaste alone on a 2–3 year old laptop typically reduces peak temperatures by 10–20°C.

## How Often Should You Clean Your PC in Dhaka?

The right cleaning frequency depends on your environment:

| Environment | Recommended Cleaning Interval |
|---|---|
| Air-conditioned, sealed apartment, no pets | Every 12 months |
| Normal Dhaka apartment (fan AC or no AC) | Every 6–8 months |
| Near a construction site or unpaved road | Every 3–4 months |
| Shop, market, or industrial workspace | Every 2–3 months |
| Home with pets (fur adds to dust) | Every 4–6 months |
| Gaming PC running 6+ hours daily | Every 4–6 months |

**Dhaka seasonal tip:** Schedule a professional clean in **March–April** (before the hot season) so your PC enters the 38–42°C summer months with maximum cooling capacity. A second clean in **October** (after monsoon) removes the humidity-clumped dust that accumulated during the rains.

## How to Check Your PC Temperature in Dhaka — Free Tools

You don't need to open your PC to know if it's overheating:

1. **Download HWMonitor** (free at cpuid.com) or **HWInfo64** (free at hwinfo.com) — both work on Windows 10 and 11.
2. Open the software and look for **CPU Package temperature** and **GPU (Core) temperature**.
3. At **idle** (browser open, no gaming): safe range is 35–60°C for CPU, 30–55°C for GPU.
4. At **full load** (gaming, video render): safe range is 70–85°C for most modern CPUs/GPUs.
5. If **idle temperature is above 75°C**, or **load temperature exceeds 90°C**, schedule a cleaning immediately.

## Frequently Asked Questions

### How much does PC cleaning service cost in Dhaka?

Professional PC cleaning in Dhaka at your home costs BDT 1,500–2,500 for a desktop and BDT 1,800–3,000 for a laptop. BAYAS prices include compressed air, thermal paste, and the home-visit fee. The visit fee (BDT 700–1,200) is credited toward the cleaning cost if you proceed. WhatsApp **01712-644590** for an exact quote.

### How often should I clean my PC in Dhaka?

Most Dhaka apartments need a PC cleaning every 6–8 months. Near construction or in dusty areas (Mirpur, Old Dhaka), clean every 3–4 months. Air-conditioned, sealed offices can extend to 12 months. The safest habit is to schedule a professional clean in March (before summer) and October (after monsoon).

### Can I clean my PC with a vacuum cleaner?

No. A household vacuum generates static electricity that can permanently damage computer components — motherboard, GPU, RAM, and SSD are all at risk. Only use compressed air (available from computer shops in Agargaon or Multiplan Center) or call a professional for safe cleaning.

### What is thermal repaste and why does it matter?

Thermal paste is the compound between your CPU/GPU chip and its heatsink. It fills microscopic gaps to conduct heat efficiently. Over 2–3 years, thermal paste dries out and cracks — reducing heat transfer by 15–30°C. Replacing it (thermal repaste) restores full cooling performance. BAYAS includes repaste in every full cleaning service.

### How long does a professional PC cleaning take?

A desktop deep clean with repaste takes 45–75 minutes at your home. A laptop clean (full disassembly required) takes 60–90 minutes. Your PC is returned fully assembled and tested before the technician leaves.

### Does BAYAS clean laptops at home in Dhaka?

Yes. BAYAS technicians carry all necessary tools (screwdrivers, spudgers, compressed air, thermal paste) for a full laptop disassembly, fan service, heatsink clean, and repaste — completed at your home. Book via WhatsApp **01712-644590**.

### What is the best time of year to get a PC cleaning in Dhaka?

March–April (before the hot season) is ideal — your PC enters summer with full cooling capacity. October (after monsoon) is the second best time — monsoon humidity causes dust to clump on fans and heatsinks. For heavily used systems or dusty areas, clean both times per year.

### Will cleaning my PC make it faster?

If overheating is causing thermal throttling (the CPU slowing itself down to reduce heat), a professional clean can noticeably improve performance. In stress tests, BAYAS customers consistently see desktop CPU temperatures drop 15–25°C and performance benchmarks improve 10–20% on throttled systems after cleaning.
