A heat pump provides both heating and cooling from one system. During warmer weather, it moves heat out of the home. When temperatures drop, it reverses operation and transfers heat indoors. This makes heat pumps a practical option for many homes in Upstate South Carolina.

Waldrop Plumbing Air Electric provides heat pump installation in Greenville, SC, and throughout Upstate South Carolina and surrounding areas. Our HVAC technicians install, repair, maintain, and replace heat pump systems. We can evaluate your current equipment, review your comfort needs, and recommend a system that fits your home.

How Does a Heat Pump Work?

A heat pump does not create heat in the same way as a furnace. It uses refrigerant to transfer heat between the indoor and outdoor units.

In cooling mode, the system absorbs heat from inside the home and releases it outdoors. In heating mode, the refrigerant cycle reverses and collects available heat from the outdoor air before moving it inside.

Heat pumps can operate during cold weather, but system performance depends on outdoor temperature, equipment design, home insulation, and proper sizing. Some homes use auxiliary or backup heat during colder conditions.

Benefits of a Heat Pump System

A heat pump can provide several advantages when it is correctly selected and installed.

Potential benefits include:

  • Heating and cooling from one system
  • Efficient operation during moderate weather
  • Consistent indoor temperatures
  • No need for separate heating and cooling equipment in some homes
  • Compatibility with ducted and ductless systems
  • Reduced reliance on combustion-based heating
  • Improved humidity control during cooling operation
  • Options for zoned comfort

Actual performance depends on the equipment, ductwork, thermostat setup, and condition of the home.

Heat Pump Installation

Heat pump installation begins with determining how much heating and cooling capacity the home needs. An oversized or undersized system may run inefficiently, create uneven temperatures, or wear out sooner than expected.

Installation may include:

  • Removing the old HVAC equipment
  • Calculating the required system capacity
  • Installing the indoor air handler
  • Positioning the outdoor unit
  • Connecting refrigerant lines
  • Installing condensate drainage
  • Connecting electrical controls
  • Updating the thermostat
  • Sealing accessible duct connections
  • Testing airflow and temperature output
  • Confirming heating and cooling operation

The condition of the ductwork should also be reviewed. Leaking, damaged, or poorly sized ducts can limit the performance of a new heat pump. Waldrop provides duct leak detection, duct sealing, and duct repair or replacement when needed.

Choosing the Right Heat Pump

The right heat pump depends on more than the home’s square footage. Insulation, windows, ceiling height, duct condition, and household comfort preferences also affect system sizing.

Important factors include:

  • Home size and layout
  • Insulation levels
  • Window type and placement
  • Existing ductwork
  • Number of occupants
  • Ceiling height
  • Sun exposure
  • Desired thermostat settings
  • Available installation space
  • Backup heating needs
  • Equipment efficiency ratings

A professional load calculation helps determine the amount of heating and cooling the home requires under typical local conditions.

Heat Pump Repair

A heat pump may continue running even when it is no longer heating or cooling effectively. Changes in noise, airflow, operating cycles, or temperature should be checked before the problem becomes more severe.

Contact Waldrop for heat pump repair if you notice:

  • The system is not heating
  • The system is not cooling
  • Airflow is weak
  • The unit runs constantly
  • The system turns on and off frequently
  • Ice forms on the outdoor unit
  • The outdoor fan does not run
  • The heat pump makes grinding or rattling sounds
  • Indoor temperatures are uneven
  • The thermostat setting does not match the room temperature
  • Energy use increases unexpectedly
  • The system switches to backup heat too often

The problem may involve the thermostat, refrigerant level, electrical controls, reversing valve, compressor, fan motor, or airflow through the system.

Heat Pump Replacement

Heat pump replacement may be more practical when the system has extensive damage, requires frequent repairs, or no longer keeps the home comfortable.

Replacement may be recommended when:

  • The system needs repeated repairs
  • Major components are failing
  • The heat pump cannot maintain the set temperature
  • Heating and cooling costs continue to rise
  • The equipment uses an outdated refrigerant
  • The system is improperly sized
  • Indoor comfort has become inconsistent
  • Repair costs are high compared with replacement
  • The heat pump is near the end of its expected service life

A replacement evaluation should include the current system, ductwork, thermostat, and any changes made to the home since the original equipment was installed.

Heat Pump Maintenance

Routine maintenance helps keep the system prepared for both cooling and heating seasons. Since a heat pump operates throughout much of the year, it may accumulate wear faster than equipment used for only one season.

Heat pump maintenance may include:

  • Inspecting the indoor and outdoor units
  • Checking refrigerant performance
  • Testing electrical connections
  • Cleaning accessible components
  • Inspecting the condensate drain
  • Checking the blower assembly
  • Testing thermostat operation
  • Reviewing system temperatures
  • Inspecting the outdoor coil
  • Checking airflow
  • Testing the reversing valve
  • Looking for signs of wear or leakage

Waldrop provides HVAC maintenance to help identify developing problems and support reliable system performance.

Heat Pump System Cost Factors

Heat pump system cost depends on the equipment selected and the amount of work required to complete the installation.

Factors that may affect the price include:

  • System capacity
  • Equipment efficiency
  • Single-stage or variable-speed operation
  • Ducted or ductless design
  • Condition of the existing ductwork
  • Electrical and control updates
  • Thermostat selection
  • Installation location
  • Removal of old equipment
  • Refrigerant line modifications
  • Indoor air quality accessories
  • Backup heat requirements

Waldrop evaluates the home before recommending equipment. Qualifying customers can pre-qualify online for financing before approved work begins.

Ducted and Ductless Heat Pumps

Heat pumps are available for homes with or without central ductwork.

Ducted Heat Pumps

A ducted heat pump uses an air handler and a network of ducts to distribute conditioned air throughout the home. Existing ductwork may be reused when it is properly sized and in good condition.

Ductless Heat Pumps

A ductless mini-split uses one or more indoor units to heat and cool specific rooms or zones. This may be a good option for additions, converted spaces, older homes without ducts, or rooms with recurring comfort problems.

Waldrop provides ductless mini-split service for homeowners interested in zoned heating and cooling.

Heat Pumps and Backup Heat

Some heat pump systems use electric resistance heat or another backup source when outdoor temperatures drop or the system needs to raise the indoor temperature quickly.

The thermostat may display “auxiliary heat” or “emergency heat” when backup heating is active. Short periods of auxiliary heat can be normal. Frequent or continuous use may point to a system problem, poor insulation, an incorrect thermostat setting, or equipment that is not keeping up with demand.

Emergency heat should not be used as a routine thermostat setting. It is intended to bypass the normal heat pump operation when there is a problem with the outdoor unit.

Our Heat Pump Installation Process

Our installation process begins with an evaluation of the home and current HVAC system.

Inspect the Existing System

We review the heat pump, air handler, thermostat, ductwork, electrical connections, and installation area.

Calculate Heating and Cooling Needs

The technician evaluates the home to determine the appropriate system capacity.

Explain the Equipment Options

We review suitable heat pump models, efficiency levels, comfort features, and any related updates.

Remove the Old Equipment

When replacement is selected, we disconnect and remove the existing indoor and outdoor equipment.

Install the New Heat Pump

The new system is positioned, connected, charged, and prepared for operation.

Test Heating and Cooling

We check airflow, thermostat response, temperature output, refrigerant performance, and system controls.

Review the New System

Before finishing, we explain the thermostat, basic operation, filter needs, and recommended maintenance.

Rachel helped me schedule several appointments, but keeping them spaced apart in a way that fits my schedule, which was no mean feat. I have lots of things scheduled and she was able to help me schedule them all without overwhelming me. (I can't get a new box to leave other reviews in, so I'll just add all 3 people who helped me and all three rate 5 stars). Josh came to the house to look at the bathroom fixture and gave me three options. He was quick, efficient and very knowledgeable. I hope he's the one who comes to do the work on the day it is scheduled. Then, Charles came to my aid when I found that I wouldn't be here on the day I had scheduled the work to be done. He quickly found an appropriate date and time, and it was a time that fit my schedule perfectly. Please rate all 3 of these technicians FIVE stars. Thank you.
