When the temperatures rise in Nairobi, your air conditioner becomes more than a luxury—it’s a necessity. But how do you know when your AC is struggling and needs attention?
At Mcool Electro Engineering Services Limited, we offer quick and affordable AC repair in Nairobi, helping you avoid major breakdowns and costly replacements.
Here are the top 5 warning signs that your air conditioner needs repair—or might even need a full replacement.
1. Weak or No Airflow

If you notice that the air coming out of your vents is weak or almost non-existent, it’s a clear sign something is wrong.
Common causes include:
- Clogged air filters
- Motor or fan problems
- Ductwork issues
Weak airflow can make your AC work harder, driving up your energy bills and reducing indoor comfort.
Quick Solution:
Get a professional inspection from Mcool Electro before minor issues turn into costly repairs.
2. Strange Noises from the AC
Air conditioners are designed to operate quietly.
If you hear:
- Grinding
- Squealing
- Banging
It could mean there’s a loose belt, a broken part, or serious mechanical damage.
Ignoring strange noises can lead to complete system failure over time.
What to Do:
Call Mcool Electro for fast AC repair in Nairobi to diagnose and fix the problem before it worsens.
3. Bad Smells from the Vents
Does your AC blow out musty, burnt, or foul odors?
This is a major red flag, often indicating:
- Mold or mildew inside the system
- Burnt-out wiring
- Dead pests trapped inside the ducts
Bad smells aren’t just unpleasant—they could be dangerous to your health.
Act Fast:
Mcool Electro offers professional cleaning and repair services to eliminate odors and restore fresh, clean air.
4. Higher Electricity Bills
Have you noticed a sudden spike in your electricity bills without an increase in usage?
An inefficient air conditioner works harder to maintain the desired temperature, leading to:
- Wasted energy
- Increased operational costs
A struggling AC silently drains your wallet.
The Fix:
Schedule a maintenance check with Mcool Electro to boost your system’s efficiency and cut down your monthly energy expenses.
5. AC Not Cooling Properly
Perhaps the most obvious sign—your air conditioner runs but your rooms stay warm.
This could be caused by:
- Low refrigerant levels
- A failing compressor
- Thermostat problems
- Dirty condenser coils
If your AC isn’t cooling, you’re not getting the comfort you’re paying for.
Solution:
Our experts at Mcool Electro can quickly diagnose the root cause and advise whether a repair or full unit replacement is the best option for you.
