Do You Service My IVT Heat Pump?
Yes, we service all IVT heat pump models, including older systems that are no longer commonly installed.
Our engineers regularly work on:
- IVT Geo
- IVT AirBox
- IVT Greenline
- IVT Greenline HE
- IVT Greenline HT
Whether you have an air source or ground source heat pump, we can carry out routine servicing, diagnose faults and provide technical advice where required.
Many homeowners contact us because their original installer has retired, changed business, or no longer supports IVT systems. We understand that finding someone familiar with older heat pumps can be difficult, which is why we continue to support these systems.
If you're unsure which IVT model you own, simply get in touch and we'll be happy to help identify it.
Why Regular Servicing Matters
A heat pump works hard throughout the year, often running for long periods to provide efficient, consistent heating. Regular servicing helps ensure it continues to perform as it should.
Like a boiler service, a heat pump service is preventative. Small issues identified during a routine visit can often be resolved before they develop into more expensive repairs. Keeping your system in good condition also helps protect the investment you've made in your heating system.
Maintain system efficiency
A heat pump works hard year-round. Regular servicing ensures it continues to run at the efficiency it was designed for, keeping your running costs down and performance consistent.
Reduce unexpected faults
Catching small issues during a routine visit is far less disruptive than an emergency callout mid-winter. An annual IVT service significantly reduces the likelihood of unexpected breakdowns.
Identify worn components early
Our engineers check all key IVT components during every service visit. Worn parts identified early can often be replaced before they cause wider damage or system failure.
Extend the lifespan of your heat pump
A well-maintained IVT ground source heat pump will outlast a neglected one by years. Regular servicing protects the investment you've made in your heating system for the long term.
Verify controls and safety features
Every IVT service includes electrical checks, alongside a full test of thermostat functions and control settings. We also verify the defrost cycle is operating correctly, which is critical to system protection during colder months.
Confidence your system is performing
After every visit you receive a full written service report. You'll know exactly what was checked, what was found, and that your IVT system is running as it should.
What's included in a heat pump service?
Every system is different, but a typical IVT heat pump service includes a thorough inspection of the heat pump and its operation. Our engineers carry out checks including:
- Cleaning the outdoor coil and fan
- Applying a corrosion inhibitor coating to the outdoor unit
- Checking refrigerant pressures and circuit performance
- A full visual inspection of the system
- Electrical checks including voltages and current draw
- Checking and monitoring flow rates, kWh usage and heat output (COP)
- Ensuring the defrost cycle is operating correctly (in winter)
- Checking expansion vessels and inhibitor/glycol levels
- Testing thermostat functions and control settings
- Backflushing the outdoor unit if needed
- Bleeding radiators and checking for airlocks
- Recording efficiency data and checking consumption levels
