If you turn on your heat pump this week and it seems to run longer than you remember, you’re not alone. Central Virginia is heading into its first real cold snap of the season. Overnight lows are expected to dip into the 30s over the next couple of weeks, with lows near the low 30s around November 13–15. Daytime highs are also expected to trend down from the 70s toward the 50s and, later, the 40s.
That first stretch of chilly nights is often when you find out how your system is doing. A heat pump that runs longer or uses backup heat may be responding normally to the cold. But some symptoms can point to a problem that needs attention.
Here’s what to look for, what you can safely check yourself, and what to consider if your system needs a repair or replacement.
Why does a heat pump feel different on cold nights?
A heat pump moves heat from the outdoor air into your home. As the air outside gets colder, there’s less heat available to collect. Your system may need to run longer to keep up, and the air coming from the vents may feel warm rather than furnace-hot.
That difference alone doesn’t mean your heat pump is broken. During colder weather, your system may also use auxiliary or backup heat to help maintain the temperature you set. A short period of backup heat can be part of normal operation, depending on your system and the outdoor conditions.
A light coating of frost on the outdoor unit can also occur. Many heat pumps have a defrost cycle that clears frost from the outdoor coil. During that cycle, you might see steam or hear a change in the unit’s sound. Those signs may be normal if they pass and the system resumes heating.
What’s normal, and what’s a warning sign?
Longer run times and occasional auxiliary heat during a cold snap can be expected. Keep an eye on how your home feels, though. You know what’s typical for your space.
Contact a professional if you notice:
- Air from the vents that stays barely warm
- The heat pump running constantly without reaching the thermostat setting
- Heavy ice that doesn’t clear after a defrost cycle
- A breaker that trips repeatedly
- Auxiliary heat running nearly all the time, including when the weather is mild
Don’t keep resetting a breaker that trips again. That can indicate an electrical or equipment issue that needs a technician’s attention.
What can you check before calling for HVAC repair?
A few simple checks can help you rule out common issues. Before you begin, avoid opening equipment panels or working on electrical components.
- Check the thermostat mode: Make sure it’s set to HEAT, not COOL. Confirm the set temperature is above the current room temperature.
- Look at the air filter: A dirty filter can restrict airflow. Replace it if it’s due, following the filter size and type recommended for your system.
- Clear the outdoor unit: Remove leaves and other loose debris around the heat pump. Keep the area around it open, and don’t chip away ice.
- Check the breaker once: If a breaker is off, you can reset it once. If it trips again, leave it off and call for service.
If those checks don’t help, or you see any of the warning signs above, it’s time to have the system diagnosed. A technician can check airflow, controls, electrical components, refrigerant-related issues, and the defrost cycle to determine what’s actually wrong.

What if the fix is more than a simple repair?
After a diagnosis, you may find that a repair is all your system needs. If the heat pump is aging or facing a major issue, replacement may be worth discussing. Ask your technician to explain the condition of the equipment, the recommended work, and why it’s the right fit for your home.
A-Advanced Home Services is a Trane dealer and can help you explore new system options. If replacement is the right path, our team can discuss installation and potential upgrades with you. Learn more about new system installation and HVAC upgrade and replacement.
You don’t have to make a decision based on guesswork. A clear estimate can help you compare the expected repair with replacement options and consider the age and condition of your current equipment.
How can HVAC financing options help?
If the recommended repair or replacement cost is difficult to manage all at once, ask about HVAC financing options when you receive your estimate. A-Advanced Home Services offers financing options for purchasing new systems or services. That may give you another way to consider a needed fix without waiting until you’ve saved the full amount.
Financing is subject to the standard application process. Ask about the available options and review the terms so you can decide what works for your budget. No specific rate or approval is guaranteed.
