Thornton, CO — local facts

Emergency HVAC Repair in Thornton: what’s different here

In Thornton the electric provider can change from one street to the next (Xcel or United Power), and that decides which heat pump rebate a homeowner can use.

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.
