Our commitment to quality doesn’t stop after installation. We believe in looking after our customers for the long haul — and that includes regular servicing to make sure every system we install continues to perform at its best.
This recent service visit in Warrington gave us the perfect chance to check in on a Vaillant aroTHERM plus air source heat pump we installed just over a year ago, and to highlight why regular maintenance is so important, especially when a property is undergoing other works.
The Background
Twelve months ago, we installed a Vaillant aroTHERM plus heat pump at a family home in Warrington as part of their transition away from a traditional gas boiler. The system was designed to run at low flow temperatures and was paired with appropriately sized radiators to maximise efficiency and comfort throughout the home.
Since the installation, the property has undergone extensive building work with renovations taking place both inside and outside the home. As is often the case, these works led to an increased amount of dust, debris and general disruption, all of which can have an impact on external heat pump units if not appropriately managed.
The Service Visit
During the first year of service, our engineer conducted a thorough inspection of the system. While the heat pump was still operating correctly and delivering heat to the home, we found it needed a thorough cleaning.
External units, like the aroTHERM plus, draw air through their coils to extract heat. Over time, and especially during nearby building works, it’s easy for these coils and filters to become clogged with dust, leaves, and construction debris. If left unchecked, this build-up can reduce airflow and put unnecessary strain on the system, affecting both performance and efficiency.
We carefully cleaned the external unit, cleared all debris, and checked the refrigerant levels, electrical components, and system pressures. We also conducted a comprehensive operational test to ensure everything was functioning as expected.
The Results
Thanks to the thorough cleaning and checks, the system is now back to peak performance. The customer reported no noticeable issues before our visit. Still, they were glad to know the unit was receiving the care it needed and relieved to avoid any future problems before they could develop.
We also took the time to provide the customer with a few simple tips for keeping the area around their heat pump clear, now that construction is nearing completion. These small steps go a long way in keeping any heating system in top shape between services.
Why Servicing Matters
Heat pumps are incredibly efficient, but like any heating system, they need a bit of TLC. An annual service helps to:
- Maintain efficiency and performance
- Prevent unexpected issues
- Extend the lifespan of the system
- Comply with the manufacturer’s warranty terms
- Give homeowners peace of mind
