HVAC Controls & Thermostats

What a control actually changes

A thermostat does not make a system more efficient. It changes when the system runs — and for most buildings that is where the money is.

The saving comes from not heating or cooling space nobody is using. A connected thermostat that has been left on its out-of-the-box schedule delivers very little of that, which is why we set the schedule up with you rather than mounting the unit and leaving.

What we fit

Brand	Range
Honeywell (with Resideo)	Simple digital through to fully programmable and connected controls
ecobee	Connected thermostats with scheduling around occupancy
Aprilaire	Digital thermostats, including models that integrate with whole-home air quality equipment

We have been installing Honeywell controls for more than forty years.

Getting the wiring right

More thermostat replacements go wrong here than anywhere else. A few things that decide what can actually be fitted:

• Multi-stage equipment needs a thermostat that can drive each stage
• Heat pumps with auxiliary heat need correct changeover control, or the strip heat runs when it should not — an expensive fault that is easy to miss
• A common wire is required by most connected thermostats and is often absent from older thermostat cable

We check before recommending, not after.

Commercial

We fit and service controls in commercial buildings as well as homes, and the occupancy-schedule argument is stronger there — an empty building overnight is a larger share of the running cost.
