If your heat pump worked fine when it was chilly but is failing you now that warmer days have arrived, check that the thermostat is turned to cooling and set on automatic. The condensation occurs from your unit dehumidifying your home. You can use rags or soft brushes for parts that are hard to reach. Another common reason for a heat pump stuck in one mode is the reversing valve is broken. For air filters, you can either clean or replace them, depending on specifications. For the outdoor coils, clean them by gently hosing them down with water. Heat pump problems are often caused by thermostat malfunctions. To keep your Rheem heat pump in good working condition, you should check the air filters every month, keep the outdoor coils clean, and inspect the blower, filters, ducts, and indoor coil for obstructions and dirt. The information given below can be helpful for you then. If your refrigerant is low, the heat pump can work poorly or even fail. A heat pump works by pulling in the heat from the air outside and cycles it into your home. Heat pump units - In HEAT mode, cold outdoor temperatures and high humidity cause frost to accumulate on the outdoor unit. Your room might not cool down even with a working heat pump due to insulation leaks. It won’t cost you too much to buy a simple manual thermostat, and if money is not an object and convenience is important, get the smart thermostat such as Google- and Alexa-friendly models, and models with the Wi-Fi and voice control.

There are ways to keep your home cool and lessen your heat pump’s workload. Set the thermostat to cool mode, a few degrees below your room’s temperature, so the thermostat calls for cooling. If it is, move on to step 3. They typically produce air that's anywhere from 85 to 92/93° F, but because our body temperature is higher than that (98.6), that air feels "cold.” Unlike furnaces which heat in short, strong bursts of “hot” air, heat pumps run longer to produce a steady stream of warm air (warm air that can feel cold to us). But when in doubt, don’t forget to contact your local HVAC service for proper maintenance. The solution is simple: clear the area around your outdoor unit. Rheem heat pumps can deliver quiet, efficient heating and cooling. Because many heat pumps can lose efficiency as outdoor temperatures fall below freezing, your system probably has a supplemental heat source – either electric resistance heating elements, or a gas or oil furnace. The inverse happens if you want it to cool and you’re getting warm air. Your heat pump not shutting off in winter (for a longer time) is nothing to worry about. Again, the heat pumps are meant to run continuously (for some time) to warm or cool the house. The condensation occurs from your unit dehumidifying your home. To test your thermostat and fix any problems, see Thermostat Repairs. In other words, the unit’s refrigerant is most likely leaking. There are various reasons why the heat pump stopped blowing cold air. What are MERV and HEPA? Fortunately, these are also reasons for your common winter problems with heat pumps. Here is the list of the most common reasons for air conditioning issues of your heat pump: Before you try to fix the heat pump, always check the thermostat first. Make sure the air filter is clean. Turn the system to “FAN” mode so the warm air from inside the house can flow over the frozen coils and defrost it. The refrigerant is not the only part susceptible to leaks. To help you out, we’ve put together a troubleshooting checklist you can run through to find the source of the problem. Checking these valves is a last resort because the heat pump will malfunction badly if the valves do. It does it automatically by reversing the refrigerant flow. A heat pump may also not be cooling because its indoor coil got iced. There are a number of malfunctions that can lead to a heat pump refusing to change to cooling mode, and one of the most common is a broken reversing valve. The “HEAT” setting will cause your heat pump to operate in heating mode and blow warm air instead, but only if there is a call from the thermostat. If it is, there may be a problem with the thermostat that’s causing it to read the temperature incorrectly or an electrical problem that’s stopping the thermostat from communicating with the heat pump. Start with the thermostat. This might be another reason your heat pump is not cooling your home. Learn how to install a window heat pump safely and simply, using DIY tips.

Many needed repairs to HVAC units happen due to faulty or loose wiring. When this happens, the unit will enter a defrost cycle. Ideally, you should only check the valves if everything else is working fine. Heat pumps actually blow air that is warm but feels cold to us. Check these parts first once you’re sure that the thermostat and the electricity are alright. Leaks or cracks in the ducts might keep the cold from efficiently cooling your home. If there is no airflow, check the air handler. The heat pump functions on the same principle as refrigerators and air conditioners: A liquid absorbs heat as it turns into a gas and releases heat as it returns to a liquid state. The air might not cool and get through properly if your coils and filters are clogged with dirt and debris. The heat pump is already doing that. Heat pumps require a heat pump thermostat. The valves ensure that the refrigerant flows in the proper direction, and there are several of them: thermal expansion valve, reversing valve, and flow control valves. Check breakers at the home’s electrical panel – make sure the breakers powering heat pump indoor and outdoor equipment are properly set. Compare evaporative coolers vs air conditioners, including the main differences and similarities. If your heat pump ISN'T reaching your set … Indoor fan is not working.

Next, check your outdoor unit is not iced over (see Heat Pump Troubleshooting Problem #1). There will also be other tips you can use to help your heat pump cool your home more efficiently. During cold weather, the heat pump’s compressor (which is housed in the outdoor unit) will still run in order to place the refrigerant under high pressure and high heat. A heat pump’s refrigerant is another crucial part of its system. When a heat pump thermostat is wired improperly, it fries electric components causing the heat pump not to run at all. It will be more susceptible to freezing if condensation comes into contact with it. Check the airflow in the vents. First of all, just check and make sure your unit was not accidentally switched to a/c mode. But if the electric bills are higher than it should be, don’t immediately blame the heat pump. A heat pump is a device that transfers heat energy from a source of heat to what is called a thermal reservoir.Heat pumps move thermal energy in the opposite direction of spontaneous heat transfer, by absorbing heat from a cold space and releasing it to a warmer one.A heat pump uses external power to accomplish the work of transferring energy from the heat source to the heat sink. It’s most likely that your thermostat is in heat mode – “HEAT”, fan-only mode – “FAN”, or it is off. Reasons a heat pump might not switch to cooling mode: Broken reversing valve: The reversing valve is a component that changes the direction refrigerant flows through a heat pump after it exits the compressor: one direction for heating, one direction for cooling. Ensure the thermostat is set to cool and the temperature is set at least 2 degrees below the current temperature of the house. For example, if your heat pump is working in the heat mode but is not in cooling mode, you might have a bad reversing valve. A heat pump may also not be cooling because its indoor coil got iced. Check your insulation. These switches are generally located on the side or bottom of the unit. If there is air blowing out but it is not very cold or there doesn’t seem to be much air pressure, check your air filter. Put your hand over a vent.
