Identify the fuel and equipment before the visit
For Loomis requests, include the property access instructions and whether the heater uses natural gas, propane or electricity. The same symptom can lead to a different diagnostic path depending on the fuel and equipment design.
For a detached office or workshop, explain whether it already has heating, cooling and suitable electrical service. A ductless proposal should address the actual space and installation route rather than treating it as another branch of the house system.
For commercial heat pumps, bring fuel type and detached spaces into the scope discussion. For major repairs, compare equipment condition and operating impact with a planned matched replacement. Residential rebate figures should not be applied automatically to a business project.
