Maintenance (Planned Preventative Maintenance)

Your air conditioning & heat pump systems are expensive, an investment and naturally you will want to protect and ensure their life as much as you would any other purchase.

The majority of manufacturers are now offering 5-year warranties (subject to contract) much like car dealerships, ND-AC can offer this and extended (7 years) for piece of mind.

However if you do not have a maintenance contract these warranties become null and void, which could result in expensive repairs even on a new system.

 So why have a Maintenance Contract?

When operating a system without regular maintenance the following can occur;

  • High Operating Costs
  • Reduced Cooling Capacity
  • Reduced Heating Capacity
  • Uncomfortable atmosphere (resulting in irritable staff and customers)
  • Can cause Sick Building Syndrome’ (unpleasant smells, bacteria, viruses etc)
  • Unhygienic for you and your clients (especially in Food Retail)
  • Water leaks (resulting in damaged goods, furnishings, customers clothing etc.)
  • Expensive repairs

Here are some examples;

Blocked Air Filter from Fresh Air AHU

Blocked Air Filter from an Air Handling Unit (fresh air?)


Dirt build up on fan blade, removed on maintenance

Fan Blade 70% blocked, restricting airflow and cooling capacity.


Blocked outdoor condenser coil, cleaned on maintenance

Blocked Outdoor Condenser Coil, caused unit to trip on high pressure.


This grille was in a Health Clinic Reception?

Unsightly air discharge grille and ceiling tiles


Fire Risk - damaged wiring caused through loose connection

Poor wiring, which resulted in overheating and electrical fire.
