When a reversing valve leaks, it leaks from the high side to the low side. To check for a leaking valve, measure the difference in temperature between the suction line from the evaporator and the permanent suction line on the reversing valve (usually the middle line on the bottom).
A reversing valve operates by a pressure difference inside a metal tube, controlled by a solenoid. … An electrical connection from the thermostat controls whether the reversing valve is energized or de-energized. A broken reversing valve will mean a heat pump that is trapped in one mode or the other.
Heat pumps do not generate either heating or cooling; instead, they transfer heat from one location to another, with the help of refrigerant. … However, it is the reversing valve that allows the heat pump to change from cooling to heating and back.
One of the most common problems with a reversing valve is that it can freeze in place. If it gets stuck in the heating position, there won’t be enough refrigerant flow available to properly cool your home.
If your heat pump is blowing cool air, you need to get your reversing valve replaced. Expect to pay between $450 and $600 to get a malfunctioning reversing valve replaced.
How Long Do Heat Pumps Last? As a general rule, the average lifespan of a heat pump is 10 to 15 years. Ultimately, how long your heat pump lasts will depend on how often you use the system and whether it receives regular maintenance.
| Part | Replacement Cost (Labor Included) |
|---|---|
| Reversing Valve | $200 – $650 |
| Fan Motor | $250 – $650 |
| Blower Motor | $250 – $950 |
| Evaporator Coil | $610 – $1,250 |
Heat pumps operate in one of two modes: with reversing valve and unit operating in the cooling phase when the solenoid coil is de-energized, or with valve and unit operating in the heating phase when the solenoid is de-energized.
Most manufacturers energize the reversing valve in cooling (but you really need to know on your specific piece of equipment). The thermostat sends a Y , O, & G call to the indoor unit to turn on the blower and the Y & O continue out to the outdoor unit.
The reversing valve controls the direction the refrigerant flows in a heat pump. … The pilot solenoid creates a pressure difference in the reversing valve through pilot tubes. This pressure differential across the reversing valve body allows an internal slide to redirect refrigerant flow.
The reversing valve is a cylindrical metal tube that has 4 valves; there is a slide inside the tube that moves back and forth when your heat pump changes modes. … When the cue comes from the thermostat to change modes, the solenoid activates and starts to slide the valve in the direction opposite of where it is.
Average cost: $3,875 – $10,000 A new heat pump can cost between $3,875 to $7,625 depending on the size of your home, energy efficient ratings, brand name, and the type of heat pump you install. A mini split ductless heat pump with 4 multi zone indoor air handler units could cost up to $10,000 to install.
Heat pumps – Heat pumps can last 10 to 20 years, depending on usage frequency, though 15 is average. Functionally, heat pumps are similar to air conditioners, but because they can provide both heating and cooling, they are typically used longer each year.
As heat pumps age, they naturally lose some efficiency. So the heat pump you installed a decade ago isn’t as efficient as the day you had it installed. And though a well-maintained heat pump can last a couple of decades, newer models are far more efficient. Your heat pump needs more and more repairs.
Check Refrigerant Levels If your heat pump is low on refrigerant, it will fail to meet cooling or heat demand. The most common cause of this is a leak. A technician can diagnose the problem, repair any leaks, and re-charge the system if necessary.
