🔧 Monday morning and straight into it! 🔥❄️

Our first job today is a full service of a Mitsubishi Ecodan Air Source Heat Pump, along with cleaning and flushing the underfloor heating system.

At S.A. Technical Services, we don’t just service the outdoor heat pump — we look after the entire heating system to make sure everything is working together efficiently.

Today’s work includes:

✅ Servicing and inspecting the Mitsubishi Ecodan ASHP.

✅ Thoroughly cleaning the outdoor unit’s heat exchanger to improve airflow and efficiency.

✅ Flushing and cleaning the underfloor heating circuits to remove trapped air and help restore circulation.

✅ Checking the underfloor heating manifold, pumps and controls.

✅ Checking system operation to help ensure the property heats evenly and efficiently.

💡 Did you know? Even a perfectly working heat pump can struggle to heat your home efficiently if the underfloor heating system has poor circulation, trapped air or blocked circuits.

That’s why we believe in servicing the whole heating system, not just the heat pump!

🔧 Another Busy Day at S.A. Technical Services! ❄️🔥

It’s been another busy day for the team, keeping homes warm and businesses running!

🏡 Site Visits – We’ve carried out more site surveys today for upcoming air conditioning and air source heat pump installations.

🔥 Underfloor Heating Repairs – We attended a property where trapped air in the underfloor heating loops was affecting performance. After thoroughly purging the air from the system, we’ve restored circulation, helping the customer get their home warm again and improving the system’s efficiency.

❄️ Commercial Refrigeration – We’re currently working at a shop in Horsham, relocating refrigerated display cabinets and making the necessary alterations to the refrigeration pipework.

🔧 Another Busy Morning at S.A. Technical Services! ❄️🔥

This morning, we’ve been out diagnosing and repairing a refrigerant leak on an Air Source Heat Pump (ASHP).

After carrying out our investigations, we successfully located the leak within the refrigeration circuit and carried out the necessary repairs. ✅

💡 Did you know?

A refrigerant leak can seriously affect the performance and efficiency of your heat pump, potentially resulting in:

❄️ Reduced heating performance
⚡ Increased electricity bills
🌡️ Difficulty reaching desired temperatures
⚠️ Compressor damage if left unresolved

Unlike a standard heating system, an ASHP relies on a correctly charged refrigeration circuit to operate efficiently.

At S.A. Technical Services Ltd, we don’t just replace parts and hope for the best. We investigate faults, identify the root cause and carry out the necessary repairs to get systems running properly again.

🔧 A Busy Start to the Week at S.A. Technical Services! 🔥❄️

Firstly, apologies for not updating you with Friday’s jobs! It’s been a busy few days, but we’re back with another look behind the scenes of life as a heating, cooling and refrigeration engineer!

🔧 Job 1 – Correcting Another Company’s Installation

Our first job today involved attending a system that had been incorrectly installed by another company.

We discovered wiring errors and temperature probes fitted in the wrong locations, causing problems with the system’s operation.

A good reminder that correct installation and commissioning are just as important as the equipment itself!

🏠 Job 2 – No Heating & Underfloor Heating Failure

Our current job (pictured below 📸) involves a property that has lost heating due to a drop in system pressure.

The upstairs underfloor heating had also stopped working, and our investigation identified a failed automatic air vent (AAV), contributing to the pressure loss and air entering the system.

🛠️ How are we fixing it?

✅ Isolating and capping off the faulty AAV.

✅ Restoring the system pressure.

✅ Using a specialist flushing and filling pump to purge trapped air from the underfloor heating circuits.

✅ Checking circulation and ensuring the heating system is operating correctly.

💡 Did you know?

Air trapped in underfloor heating can prevent entire rooms or even floors from heating properly. Simply topping up the pressure doesn’t always solve the problem — sometimes the system needs specialist equipment to remove stubborn airlocks.

📸 Today’s photo: Our specialist pump connected to the underfloor heating manifold as we work to restore circulation.

We’ll keep sharing the problems we come across, how we diagnose them and what it takes to get heating and cooling systems working properly again!

🔧 A Busy Day at S.A. Technical Services! ❄️🔥

It’s been a busy morning for us today, carrying out site surveys for customers looking at Daikin Air Source Heat Pump (ASHP) and Air Conditioning installations.

We’re now heading into an afternoon of fault finding and repairs! 🛠️

🔹 First up: A repair job to get a system back up and running.

🔹 Then: A call-out to investigate underfloor heating issues linked to an Air Source Heat Pump.

We’ll be sharing updates, photos and more information as we work through these jobs, giving you a behind-the-scenes look at what life is really like as a heating, cooling and refrigeration engineer!

Not every day is about fitting new equipment — a huge part of what we do is diagnosing faults, solving problems and keeping existing systems running efficiently.

👀 Keep an eye on our page this afternoon to see what we find!

🔧❄️ WE’VE BEEN A BIT QUIET… BUT THAT’S ABOUT TO CHANGE! ❄️🔧

Firstly, we’d like to say a massive THANK YOU to everyone who’s been visiting and viewing our page!

We’ve noticed we’ve had a lot of interest, but we have to apologise… we’re absolutely terrible at posting anything on Facebook or social media! 😂

The truth is, we’re usually too busy getting stuck into the job to remember to take photos or share what we’re up to!

But that’s all about to change!

Starting tomorrow, we’re going to take you behind the scenes and give you a real insight into the life of a refrigeration and air conditioning engineer. 🛠️

From everyday servicing and breakdowns to tricky fault-finding, unusual problems and the occasional job that doesn’t quite go to plan!

We’ll show you the good, the bad and the sometimes downright frustrating side of what we do.

No fancy production, no pretending everything goes perfectly — just a genuine look at our working days and what goes into keeping things running.

Thanks for sticking with us, and hopefully you’ll enjoy coming along for the ride!
