What Is a Heat Pump? How the Device Works

A heat pump is an HVAC device that provides both heating and cooling. In Mather and other parts of the country that rarely drop below freezing, they’re a more efficient option than installing both an air conditioner and furnace.

Like an air conditioner, this device cools and heats your home using refrigerant. In the summer, it absorbs hot air from the home and transfers it outside before releasing cooler air throughout the house. In the winter, it reverses the process to keep you warm.

Five Common Problems Every Mather Homeowner Should Know About

Heat pump troubleshooting requires significant experience and training to assess a problem accurately. Here are the five most common issues, their associated causes, and the most likely solution.

1. The Device Blows Lukewarm or Cold Air

In summer, you’ll love a device that blows cold air. However, during the winter, it’s one of the most common heat pump issues. You may also notice the device blowing lukewarm air any time of year.

What causes this problem?

• Low refrigerant levels
• Dirt buildup on the air filters or coils
• Thermostat problems like miscalibration
• Broken reversing valves

Start by checking the air filter and units and remove any accumulated dirt or debris. If that doesn’t work, you’ll need a qualified technician to diagnose and solve the problem.

2. The Device Doesn’t Operate for the Correct Amount of Time

Your heating and cooling system should run only as needed to reach the temperature on a thermostat. If it doesn’t turn on, you likely have a power issue like a tripped circuit or faulty wiring. Problems with refrigerant or the compressor can also force the heat pump to run constantly.

Short cycling occurs when the heating and cooling system turns on and off quickly. Loose wires or overheating from a lack of refrigerant are the most likely causes.

3. The Mode Frequently Switches Between Heating and Cooling

Your thermostat controls the heating and cooling functions of the heat pump. However, even when you set it on the correct mode, the following issues could cause it to switch functions randomly:

• Low batteries or calibration issues with the thermostat may force it into the wrong mode.
• The reversing valve controls the flow of refrigerant. Malfunctions could cause the device to warm when it should cool.
• Faulty wiring and other electrical issues can create communication issues between the thermostat and the heat pump.
• Low refrigerant levels cause a variety of heat pump malfunctions.
• The control board acts like the brain of the HVAC system. When it has issues, it results in widespread problems.

4. You Notice a Rise in Allergies or Respiratory Issues

Various heat pump issues cause poor indoor air quality. For example, a dirty air filter introduces more dust and bacteria into the air, leaving your family feeling sick, congested, or uncomfortable. 

Standard air filters require changing at least once a month. Homes with pets or smokers may need more frequent attention. Changing this component is one of the few tasks a homeowner can safely perform without professional assistance.

5. Visible Damage Appears on Various Components

Whether from severe weather or normal wear and tear, heat pumps can develop various forms of damage. If you notice any of the following occurrences, call for service:

• Evaporator coils may freeze even during summer.
• Rust and corrosion can form on various parts of the device.
• Condensation or water often forms if you have a clogged drain line or other issue.
• If the heat pump has electrical problems, scorch marks may appear.
• Falling tree branches or severe weather can hit the outdoor unit and break various components.
