Heat Pump Troubleshooting Advice: Before calling a heating and air-conditioning company, check the following:
- Check selections on the thermostat. Ensure that it is set to the desired settings.
- Check power supply. This can include a circuit breaker and or/a regular looking wall switch close to the unit
- Check for freezing up of air-conditioner or heat pump units. If the air conditioner or heat pump unit is frozen turn it off. Check the air filter(s) to make sure they are not clogged or obstructed in any way. If you find no problems leave the unit turned off and call a service company.
- Is the air handler blower working good and blowing air out of all of the supply vents? If not or it is weak then you likely have an airflow issue. Always make sure you have a clean filter and that all of your supply vents are open and unobstructed. If this is all good then you have another problem with the airflow. Maybe a bad blower motor or the unit is freezing up inside the evaporator coil. In any of these cases, it is time to call an HVAC repair service.
- Is the condenser fan motor turning at the heat pump condenser? Word of note. When the heat pump is in heating mode the fan will not turn while the compressor is running. This is normal and a part of the automatic defrost mode for the heat pump. If it is in cooling mode and the fan is not turning you have a problem. In cooling mode, the fan needs to run when the compressor running. If not then something is wrong (unless as noted above with defrost mode). You need to call a professional.
- Additional things to look for with heat pumps. Issues regarding heat pumps include a condenser with excessive ice on the coils in the winter. This means the defrost mode isn’t working properly and may need a minor adjustment or a repair altogether. It is best to call a pro to fix that issue. In the summer. if any ice is observed on the heat pump anywhere. You definitely have a problem with your heat pump. This includes the evaporator coil or any of the copper pipes. Finally, if any ice is observed you have a problem that needs the attention of a professional. However, before calling a professional, use this basic checklist.
This Goodman 13 SEER Heat Pump condensing unit is a new installation. The inside Goodman air handler attached to the heat pump condenser via line set was also replaced. It was replaced with this new Goodman heat pump. Its not a good idea to put a new high SEER air conditioner or heat pump condenser without matching it. It should be matched with a properly rated and efficient air handler especially the coil. (more…)
Heat Pump Frost Ice Buildup. Hi. I noticed my that one of my outside heat pump condensing units was laboring throughout the night. This morning I found ice frost buildup on the heat pump condenser fins. I live in Tucson, Az. It has been colder than normal (below freezing) with a bit more moisture in the air than usual as of late. Can you please tell me what causes this frost ice buildup, and how I go about rectifying? Does this mean that the condenser pump is shot? I’m originally from the Midwest, and have never experienced this before. What should I be doing? Thank you for your help. (more…)
Heat Pump Sequence of Operation - Every electrical-mechanical piece of equipment has a sequence of operation. While some manufacturers of heat pumps vary slightly with their heat pump sequence of operation the overall sequence of operation for a heat pump is the same for most manufacturers. So unless you have a special type of heat pump (they are out there – the Acadia heat pump is designed for extreme cold weather temperatures up North like Canada) the sequence of operation for your heating equipment should be very similar to what is described here. This is the basic operation of a heat pump like you will find in conventional heat pumps.
Goodman Heat Pump Condenser Flood Protection . This heat pump condensing unit has been installed atop the platform. The area where this air conditioning condenser is located is prone to flooding. The platform raises the heat pump condenser at least one foot above flood plain. This is usually required depending on the municipality or government agency in charge of mechanical and electrical inspections. If you live in a flood-prone area it is wise to protect the equipment from flood damage. It is possible for the air conditioner condenser unit to run after being flooded. However, the life expectancy is drastically reduced and you will definitely experience mechanical and electrical problems. (more…)
Heating with Heat Pumps | HVAC Systems . There are some people who say that heat pump heat is not as warm as other types of heat. Heating sources such as a hot water boiler or even a steam boiler. Even the forced air gas furnace gets more credit for providing better heat than the heat pump. Heat pumps are extremely popular in the southern states where the heating season is short. Additionally, where the temperature rarely dips below 35 degrees F. (more…)
Air Source Versus Geothermal Heat Pump Heating Systems . A heat pump is an electric cooling and heating system. It is used to compress and decompress gas to heat or cool a house. This mechanical device pumps heat from a cooler to a warmer location. It can extract heat from air, water or the earth. Heat pumps function like an air conditioner in the summer and an electric furnace in the winter. Therefore, encompassing both a heating and a cooling unit in one device. The COP, or coefficient of performance, calculates the ratio of heat output to electric power consumption. Therefore, COP& measures the performance of a heat pump. (more…)
How Heat Pumps Work. Heat Pumps can be a very economical way of heating and cooling your dwelling. It depends on geographical location and the cost of electricity in your area. The volatile costs of natural gas, propane, and oil has enabled these conditions. Conditions where it can be cheaper with a heat pump than with fossil fuels. There is a common conception that a heat pump blows cold air. While this can be true in some cases it is not true. If a heatpump is blowing cold air when in the heating mode then it has a problem. A problem that needs to be corrected. Even when the outside unit kicks into the defrost mode the unit should provide adequate heating. Heating to heat the zones which it serves. Again, if it is not providing adequate heating then it needs to looked at for a technical problem. A problem that needs correcting. A well-designed system, working properly and efficiently, can provide competitive and economical heating. (more…)
Heat Pump Problems | HVAC Heating & Cooling - Heat Pumps are very popular especially in the South where air source heat pumps are mostly favored over straight air conditioners with a gas furnace for heating. With a heat pump, one system can provide heating and cooling. Some people rely on a geothermal heat pump system or a water source heat pump. A geothermal heat pump extracts heat from the ground instead of the air like an air source heat pump works. (more…)
Geothermal Heat Pumps | HVAC Heating & Cooling
Geothermal heat pumps use ground water or water circulated through pipes to exchange heat with the earth. Geothermal, versus air source heat pump systems, use the earths natural temperature to exchange heat and provide heating and cooling. The temperature of the air varies widely with the weather whereas the temperature of the earth is nearly constant and makes the use of a geothermal system ideal for heating and cooling your home or business. It also costs less in energy use because of the constant earth temperature versus the widely varying temperature of the outside air. Geothermal systems make sense and can save lots of money in energy use.
