Less energy, more comfort

Most homes waste a surprising amount of the energy their heating and cooling consumes — conditioning empty rooms, running at the wrong times, or fighting against poor controls and leaky ducts. The good news is that this waste is also the easiest win. Before recommending any new equipment, Evergreen looks at how your existing system is being used and controlled, because smarter operation often delivers the fastest return of any upgrade we offer, with no major works required.

Smart thermostats are the cornerstone. A modern controller learns your routine, lets you set schedules and zones, and can pre-condition your home while solar is generating so you draw less from the grid. Geofencing means your system eases off when the house is empty and is comfortable again by the time you walk in. Pair that with proper zoning and you stop paying to heat or cool rooms nobody is using — one of the biggest sources of needless energy use in any home.

Upgrades that pay for themselves

• Smart, learning thermostats with app and voice control
• Motorised zoning so you condition only the rooms in use
• Solar-aware scheduling that runs your system on clean energy
• Inverter retrofits and controller upgrades for older systems
• Duct sealing and insulation top-ups to stop wasted air
• Performance tuning to restore lost efficiency

Measured, not guessed

We don't believe in vague promises of savings. Our efficiency review measures how your system actually performs and identifies exactly where energy is leaking away — whether that's runtime, control settings, airflow or insulation. You'll receive a clear, prioritised list of improvements ranked by likely payback, so you can start with the changes that save the most for the least, and tackle the rest in your own time and budget.

Comfort and conscience together

Every kilowatt-hour you don't use is one that never has to be generated — so efficiency upgrades are good for your wallet and the climate at once. Many of our customers find that a few well-chosen improvements deliver comfort that feels better than before while costing noticeably less to run. And because these upgrades extend the working life of your equipment, they reduce waste too. It's the rare home improvement that gives back every single month.
