The Possibilities Are Endless

A heat pump is a fantastic way to keep your Las Vegas, NV, home cozy and relaxing all year. Even better, while no HVAC equipment is indestructible, major breakdowns are quite rare. If your system isn’t providing heat when you need it, it’s likely one of a few minor issues.

Your Heat Pump Thermostat Isn’t Set Properly

It may sound embarrassingly obvious, but sometimes the simplest causes are the easiest to overlook. If your heat pump isn’t producing warm air, check your thermostat to ensure it’s in heating mode.

In addition, make sure your fan is set to “Auto” instead of “On.” When your fan is set to “On,” it will continue blowing air even when no heat is generated. Finally, your thermostat may not be properly calibrated, causing it to read the wrong temperature in your home.

The Reversing Valve Is Stuck

The reversing valve is perhaps the most critical component of any heat pump system. As you’ve probably guessed, this small component reverses the system’s operation, allowing it to toggle between heating and cooling modes.

In some cases, however, the valve can become physically stuck. If your system still cools effectively but can’t generate heat, a stuck valve is a very likely culprit.

The Outdoor Coil Is Dirty or Frozen

The coil inside your heat pump’s outdoor unit plays a key role in transferring heat between your home and the environment. If the coil is obstructed by dirt or ice buildup, heat transfer can be disrupted. Occasional frost buildup is normal and should be easily removed by the system’s built-in defrost function. However, heavy ice accumulation may indicate a refrigerant leak or other serious problems, which can significantly degrade efficiency and performance.

If you’re having trouble with your home heating system, don’t gamble on trying to fix it yourself. Call the trusted service technicians at Infinity Heating and Cooling for quick, high-quality heat pump repairs.
