4 Common Issues Heat Pumps Have During Winter

Outdoor HVAC systems that can heat and cool your house are called heat pumps. Both ducted and ductless system designs are available. Because heat pumps are efficient in terms of energy use, local utility companies frequently provide incentives for their installation.

Heat pumps have a lot of advantages, but they also have some drawbacks. In this article, we'll talk about typical wintertime problems with residential heat pumps and how to fix them.

1. Heat Isn’t Strong Enough

You may not be aware, but the heat from a heat pump feels different from heat from a furnace. The heat produced by furnaces is more powerful and intense. Heat pumps, on the other hand, operate more continuously rather than turning on and off. This uses less energy and creates a better balance of heat in your home, which makes your family more comfortable and reduces cold spots. Expert furnace repair services suggest that you should test your heat pump and double-check it's set correctly before calling in a heating repair service. When compared to other forms of home heating, this consistent operation is the biggest difference with heat pumps.

Residential heat pumps may struggle to maintain your home's heating during periods of extremely low temperatures, where they perform best. During these periods of harsh weather, we advise having a backup heat source for your heat pump. Frequently, our customers use their furnaces as a fallback heating source. If you opt to purchase a furnace as supplemental heating, only use it during extremely chilly winter conditions. You should utilize your heat pump the remainder of the time because it is significantly more energy efficient. Reach out to a quality furnace repair in Cincinnati to ensure complete utilization.

2. Ice on Your Outdoor Unit

Have you seen any ice or frost on the exterior of your heat pump? If so, don't react hastily. Your heat pump will switch to defrost mode when it detects the accumulation of ice and should thaw it away. Your heat pump will chill your house during the defrost cycle while using its thermal energy to melt the ice on the exterior unit. The defrosting procedure should be finished in ten to fifteen minutes by the defrost cycle.

After the defrost procedure is finished, if there is still ice on your outdoor unit, we advise performing these actions on your own before consulting an HVAC specialist: Have you been routinely replacing your air filter? Inspect your air filter and replace it as necessary. This will guarantee improved airflow.

Free the area around your outdoor unit of any clutter to leave 2 feet of clear space on all sides. Additionally, this will improve airflow.

See if the air is blowing out of your registers and/or vents. If not, there might be a problem with your blower motor. By using your thermostat to activate the fan mode, you may confirm this once again. If even with the fan running, no air is coming out of the registers and vents and ductwork, you know the problem is with the blower motor.

There is one more component of your heat pump system that you can examine once you are certain that the blower motor problem is not the problem. Switch on your heat pump, then go outside. If the heat pump is operating but the fan is not, the issue is most likely with the condenser fan motor.

This probably calls for a whole house fan maintenance that you should bring in professionals for. The issue may be due to seized bearings, or the fan motor may need replacement. Either way, professional HVAC technicians are best equipped to deal with this issue.

If you have followed all the instructions above and your outside heat pump is still covered in ice, you should call an HVAC expert immediately away to diagnose the problem. Due to a lack of airflow, leaving ice on the unit for an extended amount of time can cause problems with your system. An expert in HVAC would also be able to assist in the repair of a blower motor and/or condenser fan motor issue.

3. Heat Pump is Always Running

Have you ever noticed that your home's heat pump never turns off and is constantly on? This could mean that your home isn't well insulated, allowing the cold air from the outside to the inside. To keep your house comfortably warm, your heat pump will need to work harder and longer. Consider making improvements to your home's insulation and weatherization.

4. Registers and Vents are Blowing Cold Air

Are your registers and vents circulating cold air? Your household heat pump has likely finished its defrost cycle. If cold air is blowing after the defrost cycle is over, there might be another problem. The defrost cycle should only take ten to fifteen minutes. Make an appointment for a diagnostic with a local HVAC expert.

5. Indoor Air Handler Not Working

Your heat pump and an air handler collaborate to distribute air throughout your house. Your indoor air handler could not be operating if your outside unit is running but you can't feel air flowing from the registers. Your interior air handler may not be turning on for several reasons, such as:

Circuit Breaker trip
You can connect your indoor and outdoor units to different electrical systems. If your indoor unit's circuit breaker has tripped, check it. Watch out for any blown fuses as well.

Wiring Connection Issues
Additionally, the inside air handler may not be receiving electricity due to frayed or loose cables.

Blown Blower Motor
The worst-case scenario is that your blower motor has failed. The blower motor is in charge of moving air around your home. The heat pump won't be able to disperse air around your house if the blower motor blows. Sadly, you need to hire a professional to replace a blower motor that has failed. Instead, you must hire an HVAC expert to complete the task on your behalf.

6. Heat Pump Is Short Cycling

When your heat pump continually shuts off shortly after turning on, this is known as short cycling. There are various reasons for short cycling:

Improperly Sized Unit
Your home will cool or heat up too quickly if your unit is too big for it. It will turn off when it reaches the specified temperature. If you want to determine whether your heat pump is the right size for your home, perform load calculations with the help of an HVAC specialist.

Overheating System
Your system may overheat if your air filters are unclean since they can limit airflow. Therefore, as a protective measure, your heat pump turns off.

Leaks of Refrigerants
Your heat pump might not have enough refrigerant to run a full cycle if there is a refrigerant leak. A refrigerant leak can only be found and fixed by a qualified HVAC technician.
