HVAC Health Check
Maintain optimal HVAC performance and hygiene compliance with our range of HVAC maintenance and cleaning solutions. From condition assessments and filter changeouts to regular servicing, we help keep your air systems working efficiently.
What is a HVAC Health Check?
A HVAC Health Check includes the assessment, maintenance and optimisation of your heating, ventilation and air conditioning systems to ensure they remain clean, efficient and compliant. Depending on the age and condition of your system, you may only need one of these services, or all three. We tailor our approach based on what’s right for your site, whether it’s a one-off assessment, a filter change-out or regular servicing. If you already know the condition of your HVAC system and simply need a thorough clean, our Ventilation Deep Cleaning service may be the right option for you.
A HVAC Health Check can include:
| HVAC Condition Assessment | Filter Supply and Install | Scheduled Servicing |
| A full evaluation of your systems current state using visual inspections and pressure drop readings. You’ll receive a detailed condition report outlining issues and corrective actions. Visual inspections include:
| We can advise on the best filter to suit your sites environment, hygiene requirements and system performance. We supply a range of ISO16890 compliant filters. Filters we can supply:
| Our scheduled servicing involves the checking and cleaning of both clean and dirty sides of filters, carried out in line with IRHACE best practices. We provide full documentation, including maintenance reports and certificates of completion. Servicing frequency depends on factors such as:
Typically, we schedule customers for monthly or quarterly servicing, depending on these factors. |
