Due to the many practical, convenient, and environmentally friendly benefits of a heat pump, popularity has risen significantly in recent years. These systems combine heating and cooling capability into one unit, achieving perfect temperature control from the touch of a button on the wall, or even from a remote. Through years of in-field experience, intensive training, and product knowledge, the professionals from Joseph Frederick & Sons provide informed recommendations, accurate sizing, and precision installation. We handle your project with an unmatched level of professionalism, ensuring exceptional value for your investment.

Heat is found in all air. When the air temperature is 75 degrees, and 10 degrees of heat is extracted from it, the air is now 65 degrees. That’s what a heat pump does. In the summer, a heat pump absorbs heat from inside the house and sends it outside. In the winter, the heat pump reverses the flow of refrigerant and its utilization, extracting heat from the outside air by way of the compressor. A heat pump accomplishes this heat exchange more efficiently and cleaner than any other system. The reduction of fossil fuels being used also lowers the negative impact on the environment.

Through our Factory Authorization, Joseph Frederick & Sons offers our valued customers the most recognized and well-renowned name in heating and cooling. The Carrier Infinity 20 Heat Pump with Greenspeed Intelligence achieves outstanding 20.5 SEER, 13.0 HSPF, and operational noise as low as 58 decibels. Greenspeed Intelligence is created by pairing adaptable speed technology with the intelligence of Infinity Control. Qualified for ENERGY STAR’s Most Efficient 2012, this exceptional system takes comfort, efficiency, and control to a higher level.

Variable-speed technology presents unmatched comfort and energy-saving potential. Variable-speed condensing units provide operational ranges in one percent increments from 100% capacity down to 40%. The unit reacts to changing conditions in the home, determining when full capacity is not required. The unit communicates with the control, recognizing which zones need more or less capacity, and then acts accordingly. By running at lower speeds, less power is consumed, saving considerable costs on utility bills. You can even tailor home comfort preferences, customizing temperature, humidity, ventilation, air quality, fan speeds and more, from a single control.


The lifespan of your new heat pump greatly depends on care and maintenance over the years of service. Components lose efficiency and suffer greater wear and tear when dirt and grime are allowed to accumulate. The best way to prevent heat pump issues is to schedule regular cleaning and troubleshooting. With a maintenance plan from Joseph Frederick & Sons, our licensed professionals perform a number of checks, balances, and inspections, as well as comprehensive cleaning. We take on the work and worry, and make sure your heat pump delivers the consistent and efficient performance you count on to stay comfortable.
