Installing an air conditioner in your Nairobi home might seem simple—buy a unit, plug it in, and enjoy cool air, right? Not quite.
At Mcool Electro Engineering Services Limited, we’ve seen firsthand how AC installation mistakes can lead to high energy bills, poor cooling, and expensive repairs. If you’re planning to install or upgrade your air conditioning system, this guide is for you.
Let’s walk through some of the most common AC installation mistakes in Kenya—and how you can avoid them by hiring trained professionals.
Mistake #1: Buying the Wrong Size AC Unit
One of the most common issues we see in AC installation across Kenya is the wrong-sized unit. If your AC is too small, it will struggle to cool the room, running non-stop and wearing out quickly. If it’s too large, it will cool the room too fast without removing humidity—leading to a cold, clammy feeling.
Tip: Let a certified HVAC expert like Mcool conduct a proper load calculation based on your room size, insulation, and airflow needs.
Mistake #2: Poor Placement of the Indoor or Outdoor Unit
The location of your air conditioner matters more than most people think. Placing the indoor unit in direct sunlight or near heat-generating appliances can throw off temperature readings. Similarly, the outdoor unit needs enough space and ventilation to release heat effectively.
Tip: Always install indoor units away from direct sunlight and place outdoor units where there’s enough airflow and shade.
Mistake #3: Incorrect Electrical Setup
Many Nairobi homeowners attempt a DIY AC installation, only to find themselves facing electrical issues—blown fuses, tripped breakers, or even fire risks. Air conditioners require dedicated power lines and surge protection.
Tip: Always have your AC connected by a licensed technician who understands electrical codes and voltage requirements.
Mistake #4: Skipping Professional Refrigerant Charging
A successful installation isn’t just about mounting the unit—refrigerant levels must be precisely calibrated. Too much or too little refrigerant can affect performance, energy use, and even damage the compressor.
Tip: Only a trained HVAC technician can check and charge refrigerant safely. At Mcool, we use approved tools and industry guidelines for every installation.
Mistake #5: No Insulation or Poor Ductwork
Some installations are done so quickly that insulation and duct sealing are completely overlooked. Without this, you lose cool air before it even reaches your rooms—making your system work harder and increasing your electricity bill.
Tip: Proper duct design and sealing are part of every Mcool installation. We make sure your system is energy-efficient from day one.
