Energy Problems
A heat pump high electric bill in Parker usually lands in January, when a cold snap sends the system into long runs. Some increase is normal in deep cold. A bill far above last winter's, though, often means the backup heat strips are doing work the heat pump should be doing. If the checks below do not explain it, call and we connect you with an independent local contractor.

Hidden Causes
A heat pump moves heat rather than making it, so it uses much less electricity than resistance heat. Anything that forces the system onto its backup strips or makes it run inefficiently shows up on the meter. These four heat pump problems are the most common culprits.
✓
Backup heat running too often. Emergency Heat left on, deep thermostat setbacks or a mis-set auxiliary heat lockout can bring the electric strips on when the heat pump could handle the load.
✓
Low refrigerant. A slow leak reduces how much heat the system can move, so it runs longer and calls on backup heat sooner.
✓
Dirty filter or coils. Restricted airflow at either coil cuts efficiency. The system runs longer for the same comfort.
✓
Excess defrost or a stuck valve. A defrost control that cycles too often, or a reversing valve leaking internally, burns energy without heating the house well.
Parker Winters
Most Parker homes buy power from Xcel Energy, and some from CORE Electric Cooperative. Compare usage in kilowatt hours, not just the total, against the same month last year. In a cold snap well below zero, an older heat pump at this altitude loses capacity and the backup strips carry more of the load. That is expected. A jump in a mild month is not.
Do not set the thermostat way down overnight and crank it up in the morning. On many systems that recovery brings the backup strips on for an hour or more. Do not leave the system on Emergency Heat after a problem is fixed. And do not block the outdoor unit with covers or snow piles to protect it.
A high bill is rarely an emergency, but it can be the first sign of a leak or failing part that gets worse. If the AUX or EM light shows on your thermostat most of the day in mild weather, have it checked. Our page on thermostat problems covers backup heat settings.

Easy Checks
01
Make sure the thermostat is on Heat, not Emergency Heat, and watch how often the AUX indicator shows during a mild afternoon.
02
Try a smaller overnight setback of a couple of degrees so morning recovery does not lean on the backup strips.
03
A clean filter restores airflow. In a dusty Parker summer or a long heating season, check it monthly.

FAQ
The most common reasons are backup heat running too often, Emergency Heat left on, low refrigerant, dirty filters or coils, and deep thermostat setbacks. A very cold month also raises usage. Compare kilowatt hours with the same month last year to see if the jump is real.
Yes, a lot more. Emergency Heat runs only electric resistance strips or, on dual fuel systems, the furnace. Resistance heat can use roughly two to three times the electricity of a heat pump for the same warmth. Use it only while the heat pump is out of service.
AUX means the backup heat is helping the heat pump, which is normal in deep cold or during defrost. If AUX shows for long periods on mild days, the heat pump may not be keeping up, or the thermostat may be set to bring backup heat on too early.
Small setbacks of a couple of degrees can help. Large setbacks often backfire with a heat pump, because the morning recovery triggers backup heat. Many smart thermostats have a heat pump setting that recovers slowly to avoid that. Steady settings tend to work better.
Yes. With less refrigerant the system moves less heat, so it runs longer and calls for backup heat sooner. You may also notice weaker air and frost on the outdoor coil. Fixing the leak usually brings usage back down.
Some rise is normal. Heating takes more energy than cooling here, and capacity drops on the coldest nights. Cold climate heat pumps hold efficiency better at low temperatures. A rise far beyond last winter’s, in similar weather, is a reason to have the system checked.
