Heat Pump Auxiliary Heat Strip Maintenance: Optimizing Emergency Heat Function for Clark County’s Rare Cold Snaps

Don’t Let Clark County’s Unexpected Freezes Leave You in the Cold: Your Heat Pump’s Secret Backup System Needs Your Attention

When winter arrives in Clark County, Nevada, most residents don’t expect to worry about their heating systems. After all, this is the desert Southwest where daytime highs average 57°F (13.9°C) in Las Vegas, with nighttime lows dropping to 34°F (1.1°C). However, temperatures can drop below freezing in the Las Vegas Valley, with Clark County regularly experiencing multiple freeze events each year. When these rare but significant cold snaps hit, your heat pump’s auxiliary heat strips become your home’s lifeline to comfort and safety.

Understanding Your Heat Pump’s Emergency Backup System

Heat pump systems rely on a sophisticated backup heating mechanism that many homeowners don’t fully understand. Heat pump heat strips, or electric heat strips, are installed in the indoor air handling unit as a backup heat source, with almost all dealers automatically installing heating strips when installing a heat pump as it’s considered best practice. These strips function differently from your heat pump’s normal operation—an electric heat strip works like a toaster, generating heat through electrical resistance, where electricity flows through the resistive elements and the encountered resistance generates heat.

The key distinction between auxiliary and emergency heat is crucial for Clark County homeowners. Your auxiliary heat will kick in on its own when it’s needed by your heat pump, and you don’t have to give it a thought or switch anything over on your thermostat—just leave your thermostat’s setting on Heat, and let it do its thing. However, emergency heat is meant to be a true backup for your heat pump if there’s an emergency and the heat pump system stops working, completely taking over heating your home and shutting down your heat pump, which is completely within your control and requires switching your setting from Heat to Emergency Heat on your thermostat.

When Clark County’s Desert Climate Turns Challenging

Clark County’s unique desert climate creates specific challenges for heat pump systems. As Clark County Deputy Fire Chief Brian O’Neal emphasized, “Freezing temperatures in Southern Nevada can take people by surprise this time of year,” with temperatures falling to 32 degrees or lower, posing risks to people and homes. According to Clark County, a temperature of 32 degrees or less in the desert can damage vegetation and freeze pipes, causing them to burst.

Your heat pump’s auxiliary heat typically activates when the outside temperature is below 40 degrees or a set aux heat trigger temperature, the heat pump is in defrost mode, or if you raise the heating temperature by more than 3-4 degrees. In Clark County’s climate, this means your auxiliary heat strips may not operate frequently, but when they do activate during those rare cold snaps, they need to function flawlessly.

Essential Maintenance for Optimal Performance

Regular maintenance of your auxiliary heat strips is critical for several reasons. To ensure efficiency and longevity, heat strips require regular maintenance, including inspections for damage, cleaning filters, and checking for proper functionality. A well-maintained heat pump runs more efficiently, and after heat pump maintenance tune-ups, components are clean, airflow is balanced, and your system isn’t overworking, which can minimize the need for auxiliary heat and help lower auxiliary heat cost.

Professional maintenance should include thorough inspection of the heat strip elements, electrical connections, and control systems. Since heat strips are much less energy efficient than a heat pump, which is why heat strips are designed into these systems for auxiliary or emergency use, ensuring they operate only when necessary and at peak efficiency is essential for managing energy costs.

Warning Signs That Require Professional Attention

Clark County homeowners should watch for several warning signs that indicate auxiliary heat strip problems. Skyrocketing bills often indicate the system is relying too heavily on the backup strip heat, constant running where the system runs non-stop but the house doesn’t feel warm, and strange noises like grinding or banging sounds could indicate mechanical distress in the outdoor unit—if you spot these issues, schedule HVAC maintenance immediately.

Additionally, if your thermostat is stuck on AUX HEAT and it’s above 40 degrees, you may need to call for service. This is particularly important in Clark County, where mild winter days should allow your heat pump to operate without auxiliary assistance.

Maximizing Efficiency During Cold Snaps

When Clark County experiences its rare but intense cold weather events, homeowners can take steps to minimize auxiliary heat usage and maintain comfort efficiently. Keep the temperature around 68 degrees, bump up the temperature only a degree or two at a time, and seal windows and doors to prevent heat loss. Since extreme cold can force a heat pump system to draw on supplemental strip heating, it’s important to keep your thermostat at 68 degrees or as low as you can stand—the less your system kicks on and off during extreme cold, the less work the heat pump will have to do and the less auxiliary heat it will need.
