How Does a Heat Pump Work?

Heat pumps do not generate heat; rather, they allow heat to flow from one place to another. Heat energy naturally prefers to move to areas with lower temperatures and lower pressure.

It absorbs heat energy from the outside air and transfers it to the indoor air through the indoor unit, even in cold temperatures.

Heat pumps rely on this physical property by exposing hot air to cooler, lower-pressure environments, allowing the air to naturally transfer.

This is how a heat pump functions. Thus, the installation of a heat pump is composed of an outdoor and indoor unit to power the heating and cooling capabilities.

Heat pumps can also be customized. For example, a mini split is customizable and gives more control to the user. It can be used with a gas furnace to share the heat burden.

FUN FACT: It’s evident from the name itself that heat pumps are supposed to HEAT your home. But did you know that they can also COOL your home like air conditioners?

That’s right — heat pumps have cooling abilities like air conditioners to save you from the external heating brought by the summer!

A heat pump and an air conditioner are actually functionally identical when it comes to cooling.

Like an air conditioner, it can absorb air from the indoor air and release air through the outdoor unit to cool indoors.

Types of Heat Pumps

Now that you understand how they work, you also have to know the several types of heat pumps before buying one.

  1. Ground Source – Ground source heat pumps transfer heat between the airflow inside a home and the ground outside a home. The ground has a more constant temperature. Thus, the electrical power needed is less compared to other heat pumps.
  2. Air Source – Air source heat pumps flow heat between the air inside a home and the air outside a home.
  3. Mini Split – A mini split has two main parts: The compressor or condenser installed outside the house and the air handling installed inside the house. These various components that make up a mini split help control airflow. A mini split is ideal for home additions because expanding existing ductwork can be difficult in some cases. The installation of a mini split is more stress-free!

Things to Look for in a Quiet Heat Pump

When looking for the quietest heat pumps, one thing to look at is the decibel level.

The quietest heat pumps on the market today have a decibels rating of around 50.

Decibel levels are a unit of sound level, so the LOWER it is, the MORE SILENT it would be!

Aside from decibels as a measure, here are other features for quieter operation:

  • Insulated compression compartments
  • Variable speed compressors
  • Forward-swept fan blades
  • Quiet mount split post-compression grommets
  • Discharge or “external silencer” muffler

Aside from searching for the quietest heat pump on the market, it’s also vital to consider these other factors and features:

1. Price

The majority of heat pump brands are owned by a small number of parent companies. These heat pumps have similar components; thus, price is a deciding factor.

In general, this is because a higher-priced heat pump does not necessarily imply a better heat pump.

The truth is — there isn’t much of a contrast between these models.

Market conditions created by the parent company’s marketing efforts and dealer contracts are what dictate price!

Just try to go for the most suitable price range for your budget, including the actual unit and additional fees (i.e., installation, consultations, etc.).

2. HVAC Contractor

As the saying goes, “A hammer is only as useful as the carpenter who wields it.”

This best describes how the installation of a heat pump works.

In many cases, selecting a reputable contractor to install is more important than the product itself!

3. Location

Because of the harsh environment, if you live within a mile of the beach, your heat pump system will NOT last long, typically only 10-12 years, and even less for beachfront homes.

Routine maintenance will help extend their lifespan by a few years, but the elements will eventually take their toll!

If you live away from the coast, where the weather is milder, you can expect your heat pumps to last 20 to 30 years.

Consider your location to help you plan out your budget and future maintenance expenses!

4. Future Plans

If you intend to retire in your current home, investing in a more reliable and trustworthy heat pump brand may be a wise investment move.

If you intend to relocate within the next few years, consider repairing your current system or plan an installation of a new one at the lowest price possible.

5. Maintenance

How you care for a heat pump system is, in the end, the MOST IMPORTANT factor for its longevity.

Any brand you buy will break down sooner or later if it is not properly maintained, so if you notice something is off, take care of it ASAP.

6. Home Energy Efficiency

It’s critical to have a comfortable, safe, and energy-efficient home. Thus, it is important to invest in the proper operation of your heat pumps.

An Energy-Star rated heat pump will be useless if your home cannot contain the system’s power output!

Consider making your home energy efficient by upgrading insulation, ductwork, windows, and doors before you install your heat pump to save money on your energy bills.

Heat pumps are rated for their energy usage in two ways:

Seasonal Energy Efficiency Ratio (SEER) Rating

  • SEER rating measures the cooling efficiency of heat pump cooling systems.
  • A SEER rating ranges between 14 and 27. SEER ratings for ductless heat pumps can exceed 30, while a mini split heat pump can range from 13-21
  • A higher seer rating means better efficiency. The SEER rating is only a maximum and may not be achieved all of the time.
  • If you live in a low-temperature climate where the summer months do not experience extreme hot air, the SEER rating may be less important than the HSPF rating. A 13 or 14 SEER heat pump will most likely be more than adequate for your needs.

Heating Seasonal Performance Factor (HSPF) Rating

  • HSPF rating is a measurement of the heating efficiency of a heat pump system. Ratings range from 7.7 to 14. A mini split usually is 8-10.
  • The higher the number, the more efficient the heat pump is in heat mode. This is only a maximum efficient level, and the system may not achieve this level at all times.

Frequently Asked Questions

If you have more questions about heat pumps, this FAQ section has important tidbits of information you might be interested in.

Are Heat Pumps Noisy?

As we said earlier, heat pumps naturally produce sounds because the condenser fan needs to draw outside air across coils for heat transfer.

Thus, it’s not abnormal for new heat pumps to produce noises.

You can also scroll further down to check other normal sounds you may experience with your heat pump.

If your heat pump makes swooshing noises and becomes louder than usual, it’s most likely just the heat pump entering DEFROST MODE.

Compressors are frequently to blame for the continuous loud operational noises, but this is usually not a cause for concern.

However, if you think there really is something wrong, you can check out the next FAQ for in-depth instructions to help you out.

How Do I Make My Heat Pump Quieter?

A heat pump should last 12 to 15 years and become noisier as it ages. Some maintenance and repair steps can be taken to quiet heat pumps.

Here are some suggestions that will hopefully decrease the noise and improve your quietest heat pumps:

1. Examine the Unit to Find the Noise Source

  • Inspect the heat pump for loose or damaged parts that can contribute to the noise, such as damages to the grill and housing, the presence of animal or insect nests, or even screws and bolts that have become loose.
  • Examine the interior to see if there is any visible damage, evidence of a leak, or a worn belt.
  • Using a level, check to see if the unit and the fan are level. Examine this to see if it wobbles. Inspect the motor and fan driveshafts, as well as the bearings, for dirt or grease buildup. Sometimes the fan motor can get moisture, so it’s important to dry it out.
  • During colder weather, snow and ice buildup can disrupt normal operation, causing both noise and damage. Maintaining the unit’s cleanliness will improve its operation and protect the heat pump.

2. Level Heat Pump

  • Leveling the unit may appear to be a simple task, but take precautions when handling the copper connections running between the building and the appliance as they can crack or break if not handled carefully.
  • If it is wall-mounted, check the bolts to ensure they haven’t come loose.

3. Clean Out Fan Blades

  • Dirt buildup causes fluttering or wobbling. It should spin freely, and the blades are not damaged.
  • Consider replacing the fan with a quieter one if it is damaged or noisy

4. Tighten Down Loose Screws, Nuts, and Other Loose Parts

  • Overtightening can cause fasteners to break or strip.
  • Make sure also that the refrigeration coils aren’t constrained, as they need to be able to flex.

5. Replace Loudly Humming Electrical Components

  • Contactors must be opened and closed repeatedly, and as they age, they become dirty, worn, and louder. Contacts and relays can also deteriorate with age and use, becoming burnt or pitted and resulting in a louder hum. The cost of replacement parts isn’t prohibitively expensive.
  • Another component that can hum and vibrate loudly over time is the reverse valve. An electromagnet (electric solenoid) in the valve switches the unit between heating and cooling modes. This is a costly repair. If you hear electrical crackling or arcing, turn off the unit and call for service to address a potentially dangerous electrical problem.

6. Install Vibration Dampeners and Anti-Vibration Pads

  • Excessive compressor vibration can cause extra noise, which can bother you and your neighbors.
  • The installation of anti-vibration pads or vibration dampeners on the bolts should reduce this.

7. Compressor Blanket Wrap

  • It’s important to monitor and control compressors as they may get loud as they age.
  • The louder it is may indicate that the compression ratio, refrigerant pressure, or charge should be checked.

8. Build Sound-Deadening Enclosure for a Heat Pump

  • A noise barrier installation could be a good solution. Always leave enough space around the unit for air circulation and maintenance and repair access.
  • Use insulated blocks or acoustic panels as a barrier. Planting shrubs is a more natural option that may look better than a built fence. However, keep it in place so that it does not interfere with the heat pump’s operation.

9. Call for HVAC Service

  • Sounds indicating low refrigerant, coolant leaks, or refrigerant in the compressor necessitate a service call. Unusual or loud noises and the need to replace the heat pump motor are all reasons to seek professional advice.
  • If you’re not comfortable performing maintenance or repairs, a service or maintenance plan may be appealing. Always get a service and repair quote. If the heat pump is old, replacing it with a quieter model may be more cost-effective.

Are Heat Pumps Louder Than an Air Conditioner?

Compared to air conditioners, heat pumps are LOUDER and have higher decibels.

However, note that heat pumps are more VERSATILE than an air conditioner since an air conditioner is limited to only cooling.

These are some sounds to expect that is normal and part of a heat pump’s operation. Thus, they shouldn’t be a concern!

  • When a heat pump starts up, the scroll compressor usually is loud. It occasionally sounds like the entire heat pump is trembling.
  • When shutting down, heat pumps make a clicking or tapping noise
  • Your heat pump may make unusual noises during the winter as it reverses the heating process through the reversing valve. Heat pump owners should become accustomed to hearing swooshing sounds when their heat pump enters defrosting mode in the winter.
