What Causes Leaks in HVAC Systems?

Leaks in air conditioning and HVAC systems are more common than many realise—especially in London’s high-demand, climate-controlled environments. Whether you manage a smart cooling setup in a Hampstead apartment or a ducted VRF system in a Kensington office, the causes of leaks tend to follow similar patterns.

Typical issues include blocked condensate drains, cracked drip trays, poorly installed drain lines, or refrigerant line damage. Over time, internal corrosion, fluctuating system pressure, or vibration from worn parts can lead to leaks that aren’t immediately visible. These faults not only affect performance but can also cause structural damage if left unresolved.

At RightAir Solutions, our engineers specialise in pinpointing hard-to-find faults using a multi-layered approach tailored for high-performance cooling systems.

Our Leak Detection Process for AC and HVAC Systems

Every inspection begins with a precise diagnostic workflow designed to locate the leak without damaging finishes or disrupting your space. Depending on the system and property type, we may carry out:

  • Thermal imaging leak detection – to identify cold spots from moisture or refrigerant escaping from concealed pipework

  • Tracer gas testing – highly effective in locating microfractures in pressurised refrigerant lines or condensate pipes

  • Pressure testing – to confirm sealed system integrity and measure pressure drops across HVAC circuits

  • Moisture mapping – used to track the path of escaping water through walls, floors, or ceilings

  • Visual endoscopic inspection – to assess internal cavities behind walls or within ceiling voids without invasive work

  • Drain line assessment – verifying that your condensate system is draining properly and free of blockages

  • Consumption testing – useful for detecting subtle water leaks in systems that cycle continuously

Our process separates harmless condensation from damaging internal leaks—and gives you a clear path forward. Whether the problem affects a compact split system or a multi-zone VRF setup, our team delivers fast, clean results with minimal disruption.

From luxury flats to high-traffic commercial spaces, RightAir’s professional leak detection services are built around accuracy, speed, and long-term reliability.

Spot the Warning Signs of Leaks Before Damage Spreads

  • Pooling water beneath indoor AC units may suggest a blocked drain or cracked tray

  • Ceiling or wall stains can be caused by slow, hidden leaks within your system

  • Hissing or bubbling noises might indicate a refrigerant line rupture

  • Unexpected pressure drops could reveal internal system breaches

  • Persistent damp smells are often linked to mould from trapped moisture

We investigate these early symptoms using advanced moisture mapping technology to locate the leak accurately—before it becomes a bigger problem.

Specialist Leak Detection Technology – Precision Tools, Minimal Disruption

At RightAir Solutions, we use advanced, non-invasive tools to detect hidden leaks in air conditioning and HVAC systems across London. Our engineers are trained to interpret data from multiple sources to locate faults accurately—without damaging your property.

Here’s what sets our process apart:

  • Thermal imaging leak detection reveals temperature variations that help trace hidden pipework behind walls, under floors, or inside ceilings

  • Tracer gas testing involves introducing a harmless inert gas into the system, which escapes through even the tiniest cracks—detectable through solid materials like tile, timber, or concrete

  • Acoustic listening devices amplify sound frequencies produced by escaping water, helping us locate leaks deep within wall cavities or pipe runs

  • Endoscopic inspection cameras give us a clear view inside enclosed or difficult-to-access areas without removing finishes or fittings

  • Moisture mapping tools like digital protimeters help us chart damp levels across surfaces, pinpointing exactly where the moisture is concentrated

  • Water consumption analysis allows us to detect unexplained usage when all outlets are shut off—ideal for identifying slow, hidden leaks

  • Pipe pressure testing is used to verify system integrity and confirm the presence of leaks in sealed or pressurised pipework

Our approach to professional leak detection services is designed to be fast, clean, and precise—protecting the structure and comfort of your property while ensuring reliable long-term performance.

When Repeated Leaks Mean It’s Time to Rethink

If your AC system keeps springing leaks—especially in older pipework or joints—it might be a sign of deeper material fatigue. Rather than patching the same fault over and over, we help you assess whether targeted upgrades or part replacements are more cost-effective. With heating system water loss as a common symptom in ageing setups, our team offers data-driven advice to keep your property dry, safe, and future-proofed.

Signs That Point to a Leak

Puddles forming near your outdoor unit may indicate a cracked drain pan or overflowing condensate line
Discolouration on walls or facades could result from slow, external leaks seeping from pipe runs
Visible corrosion or scale around pipe joints can signal moisture escaping from worn fittings
All assessments are completed without disturbing your AC’s airflow or external efficiency

When a Leak Becomes a Liability

Air conditioning systems shouldn’t leave visible moisture around the property. If they do, the problem may be more than surface-level. Outdoor units showing signs of saturation or water runoff may require immediate attention. That’s where leak detection for high-end properties London comes in—designed to protect finishes, facades, and peace of mind.

Prevent Moisture Damage with Precision Repairs

We isolate the issue fast and fix the root cause—whether it’s a drainage fault or refrigerant leak. From smart flats and period homes to offices and retail units, our team keeps London’s properties safe, dry, and leak-free.

Answers to Common Noisy Air Conditioning Questions

If you have a question of your own, then please ask.

If you’ve noticed water around your unit, damp smells, or inconsistent performance—especially in concealed systems like ducted or VRF units—it’s worth booking a leak detection survey. Even a small leak can lead to mould, property damage, or system failure if ignored.

Not at all. We use non-invasive methods such as thermal imaging and tracer gas testing. Whether you’re in a Hampstead townhouse or a commercial space in Notting Hill, we identify the source without damaging walls, floors, or ceilings.

Yes. Our team is trained in both water and refrigerant leak detection. This includes issues with VRF systems, split units, and server room cooling—common across London’s high-spec residential and commercial properties.

Most surveys take between 1–3 hours, depending on property size and system complexity. For larger homes or commercial buildings in areas like Kensington or Maida Vale, we recommend allowing a little more time.

We use advanced tools including thermal imaging cameras, acoustic sensors, moisture mapping technology, and tracer gas. This helps us pinpoint leaks without the need for invasive inspections.

Yes. In many cases, we can offer same-day repairs. If the issue requires specialist parts or a larger intervention, we’ll provide a clear plan and, where needed, coordinate the follow-up repair.

Absolutely. We regularly work with shops, clinics, offices, and apartment blocks across West and North West London. We tailor our surveys to minimise downtime and disruption for staff or tenants.
