Lone Tree, CO — local facts

Emergency HVAC Repair in Lone Tree: what’s different here

Lone Tree publishes its own HVAC design values: a -3°F winter design temperature, 90°F summer dry bulb and 6,343 heating degree days. Unlike its CORE-served neighbors, the city is Xcel for both gas and electric.

What counts as an emergency

No heat when overnight lows are near freezing, a gas smell, a CO alarm, water leaking from the furnace or water heater, or no cooling for elderly residents, infants or anyone medically vulnerable.

While you wait

Check the breaker and the furnace switch, replace a clogged filter, and make sure the thermostat has batteries and is set to HEAT or COOL. If you smell gas, leave the house and call Xcel Energy from outside.
