Heat pump install: “We had Matt install our new 2-tonne Mitsubishi Heat Pump/Air Conditioning Split System”
After hours or holiday callout: “Matt came to the house on short notice, on Christmas Eve as the furnace wasn't turning on”
Thermostat setup: “set up the Ecobee that he had, with me and once setup the furnace was back to working condition”
Came back under warranty: “He did not charge me for additional diagnostic and part since he could not fix problem”
Honest about what was needed: “he opened up the connection for the humidifier to show me that it was in fact very clean so there is no need to clean them”

Themes come only from the Google reviews already stored against this listing, and each one carries the reviewer’s own sentence. A listing with fewer than three stored reviews gets none at all.
