⚠️ The Real Cost of Cheap Air-Conditioning Installations
Everyone loves saving money… but when it comes to air-conditioning, a “cheap install” often becomes the most expensive mistake you can make.
We repair systems every week that have failed long before their time — not because the unit was bad, but because the installation was done poorly.
Here’s what really happens behind the scenes 👇
⸻
🔧 What Cheap Installations Usually Cut Corners On
1️⃣ Incorrect pipework insulation
Cheap installers often use thin, poor-quality insulation or they don’t insulate all the way.
This causes:
• Condensation on the copper lines
• Water running down walls
• Frosting and incorrect refrigerant behaviour
• Compressor strain and eventual failure
2️⃣ Cheap fittings and materials
Low-grade copper, flare nuts, brackets, and insulation fail under pressure.
Common issues:
• Gas leaks
• Cracked flares
• Rusted brackets
• Loose pipe connections
3️⃣ Wrong-sized units installed
A big mistake we see constantly.
Oversized units short-cycle and kill compressors.
Undersized units run nonstop and overheat.
Both shorten the life of the system dramatically.
4️⃣ No proper vacuum pulled
A good system needs moisture removed before charging.
Cheap installers skip this step completely or do a quick “pretend vacuum.”
Moisture in the system leads to:
• Acid formation
• Oil contamination
• Blocked expansion valves
• Early compressor failure
5️⃣ Incorrect electrical protections
Some installers do not upgrade switchboards or RCBOs.
This can cause:
• Nuisance tripping
• Overheating wiring
• Fire risks
• Voided manufacturer warranties
6️⃣ Poor drain installation
Incorrect fall or location leads to:
• Water dripping into ceilings
• Mould issues
• Internal fan corrosion
7️⃣ Gas charge not weighed in correctly
They “top it up by feel,” which is dangerous and incorrect.
Too much refrigerant = high pressure = blown compressor.
Too little = no cooling = overheating and damage.
8️⃣ Hidden damage from poor workmanship
Kinked copper, crushed insulation, pipe rubbing against bricks —
all things we find constantly.
These issues slowly destroy the system from the inside out.
⸻
🔥 End Result?
Cheap installations almost always lead to:
❌ Higher energy consumption
❌ Loud operation
❌ Constant breakdowns
❌ Blocked evaporators
❌ Fan and motor failures
❌ Compressor failure (the most expensive part)
❌ No manufacturer warranty because the install wasn’t done correctly
A $300 “saving” today becomes a $2,000–$5,000 problem later.
