Our Commercial Air Conditioning Maintenance Services

Our F-Gas-certified team provides expert servicing, repair and maintenance for all air con systems, including Daikin, Samsung, and Mitsubishi units.

With decades of combined experience and expertise, our engineers perform precise diagnostics, performance optimisation and repairs.

We offer two options when it comes to commercial HVAC maintenance for Glasgow businesses.

Planned Preventative Maintenance

Preventive maintenance is crucial for any HVAC equipment to prevent inefficiencies, breakdowns and premature wear and tear. A well-maintained system enhances energy efficiency, ensures consistent cooling and heating, and prolongs the lifespan of your air conditioner. 

At G2Ref, we offer comprehensive commercial air conditioning maintenance contracts in addition to our installations. Through regular maintenance, we detect issues before they escalate and lead to costly repairs. Our technicians check refrigerant levels, electrical components, air filters, and evaporator coils to ensure optimal performance, proper functioning, and compliance. 

With our commercial AC maintenance contract, business owners receive:

  • Regular maintenance visits
  • Bi-annual equipment tests
  • A detailed report from our highly skilled engineers 

Emergency Air Conditioning Repair 

A sudden AC unit breakdown can disrupt operations and jeopardise temperature-sensitive products, leading to costly stock losses.

That’s why regular maintenance and repairs are essential for protecting your business’s operations and minimising downtime. Our expert engineers can service any air conditioning unit, regardless of brand or type.

Types of Commercial Air
Conditioning Systems We Service

G2Ref offers expert air conditioning maintenance tailored to your unique requirements. We maintain all commercial air conditioning systems, including wall-mounted, ducted and multi-split units, to ensure optimal performance.

Why is Commercial AC Maintenance Necessary?

Neglecting regular air conditioning maintenance can lead to poor performance. In Glasgow’s unpredictable climate, a poorly maintained HVAC system can impact staff performance, electronics, and the longevity of on-site products.


Regular commercial air conditioning maintenance helps businesses avoid:

  • Non-compliance with F-Gas Regulations: Non-compliance with UK government legislation can lead to fines and increased environmental impact, as well as workplace safety risks.
  • Poor indoor air quality & health risks: Blocked filters and dirty coils can cause mould, unpleasant odours, and inadequate ventilation. Polluted air puts staff and visitors at risk of health risks such as respiratory infections and asthma.
  • Reduced energy efficiency: A malfunctioning air conditioner leads to higher running costs, an increased carbon footprint and lower energy efficiency.
  • Voided warranty: Many manufacturers require periodic air conditioning service and maintenance to retain warranty coverage and ensure equipment longevity.


Keep your systems clean, efficient and compliant with regular maintenance from G2Ref.

FAQs About Our Commercial Air Conditioning Maintenance

Here are our answers to some common questions about our commercial AC unit maintenance.

Most air conditioning systems should be serviced at least twice a year to prevent breakdowns. High-traffic environments, such as retail and hospitality, may require quarterly maintenance to maintain good air quality and efficiency. The annual servicing does not include your regular maintenance checks.

A few warning signs can include poor cooling performance, higher electricity bills and unusual noises or odours coming from your unit. These signs may indicate low refrigerant levels, blockages in the filters or coils or components that need recalibration.

There are several reasons why your system could be experiencing water leaks. These include:

  • Clogged drain lines: Dirt, dust, and algae can block the condensate drains, causing water backup and leaks.
  • Dirty air filter: A clogged filter can restrict airflow, leading to frozen coils that eventually melt and overflow.
  • Low refrigerant levels: These cause the coils to freeze and then thaw, leading to excess water.
  • Damaged or disconnected drain pan: If the drain pan is cracked or misaligned, it won’t properly catch condensation.
  • Improper installation: If the AC unit isn’t level, water may not drain correctly.

Should your AC unit be experiencing any water leaks, contact G2Ref for expert air conditioning service and maintenance.

No, it is not necessary to cover your outdoor AC unit during winter. Modern units are designed to withstand harsh weather conditions. However, if your unit is exposed to heavy rain, snow or falling debris, a breathable cover can offer some protection. 

Avoid fully sealing it, as this can trap cool air and encourage rust or mould growth. Regular maintenance before and after winter is the best way to keep your AC in top condition.

First time we had an air conditioning unit installed in a server room- entire install less than a day for a top of the range fixed unit! Second time we had a freezer break down - G2 on site within the hour, diagnosed with in another and parts ordered for fitting the next day! They even helped us arrange a freezer trailer to put the stock in whilst our freezer was out of action. Staff always professional and very polite.

We needed to engage with a refrigeration contractor that could support our exponential growth & development over the last 4 years. G2 have project managed the design & installation of our large scale chilled storage facilities in our 7 depots around Scotland & England with great success. I have found that their quality of workmanship has been excellent and I look forward to working with Grant & the G2 team in future.

Subway have been working loyally with G2 for over 4 years . Their response times are same day or next day at the latest for less urgent issues. The communication from G2 on a whole is hugely impressive, from the engineers dealing with our staff on site and the admin team in the office. G2 service and maintain our 40 plus stores and have no issues meeting urgent response times to multiple stores on the same day. We have a very strong and reliable relationship with G2 and look forward to continuing our work with them in the future.
