About Larkspur
Larkspur is a home rule town in southern Douglas County, incorporated in 1979. Interstate 25 runs along its eastern edge, and the Colorado Renaissance Festival fills the hills just west of town on summer weekends. Castle Rock is about 11 miles north. Here is what that setting means for a heat pump.
✓
Thinnest air on the line. At nearly 6,900 feet the air holds less heat for a heat pump to collect. Capacity drops sooner as temperatures fall than it does in Parker.
✓
Valley cold. The East Plum Creek valley can trap cold air overnight. Homes on the valley floor may see colder mornings than homes on the slopes.
✓
Heavier snow. Higher ground south of Castle Rock can pick up more snow than the Parker area. Snow piled against the outdoor unit blocks airflow.
✓
Wildfire smoke and dust. Foothill homes can see ash and dust in dry seasons. A dirty filter or coil cuts airflow in both heating and cooling.
Altitude Effects
Most heat pumps are rated at sea level. Every thousand feet of elevation thins the air a little more, and the outdoor fan moves less air mass with each turn. In Larkspur that shows up as more frequent defrost and earlier reliance on backup heat when nights turn bitter.
For homes here, a cold climate heat pump or a heat pump paired with a furnace often copes better than an older standard unit. If yours is a standard unit, it is not broken just because backup heat runs often in January. It is broken if the house cannot hold temperature with backup running.
Mini splits are common in cabins, workshops and additions around the foothills. They are efficient in mild weather but have small drain lines that can freeze. A wall unit dripping water indoors in winter usually means its drain is blocked or frozen.

High Country Checks
01
If the thermostat shows Aux Heat but rooms stay cold, the backup may have failed too. Note it for the contractor.
02
After a storm, clear snow from the sides and top by hand. Keep the base clear so defrost water can drain.
03
Replace a dusty or ashy filter. In smoky seasons you may need to change it more often than the package suggests.
Service Areas
The line also covers Castle Rock to the north, Sedalia further up Plum Creek and Castle Pines. Larkspur addresses use the 80118 ZIP, and calls from the surrounding hills are welcome too.
FAQ
No. Contractors work on heat pumps through the winter. Some checks, like refrigerant charge, are easier to judge in mild weather, but most repairs can be done in the cold. The contractor will tell you if anything should wait.
At high elevation, air from a heat pump can feel cooler than a furnace even when it is working. Truly cold air for long stretches is a problem. See the blowing cold air page for causes.
Turn it off and put a towel or container under it. A blocked or frozen drain line is the usual cause. Mention it when you call so the contractor brings what they need.
Yes, though fewer do than in the north metro. Contractors often come down from Castle Rock or Parker. Availability depends on the day.
Leave it off after one reset. Repeated trips point to an electrical fault, which can be dangerous. Switch off the system at the thermostat too, then call.
An independent local contractor. The line itself does not employ technicians or do repairs. It simply connects your call.
