The invention of the refrigeration process in the 1940’s has opened the door to a huge range of possibilities for convenience and comfort. Imagine life without being able to freeze your meat or preserve your leftovers. Fred’s Plumbing and Heating also makes use of this technology by installing Lennox air conditioning and air to air heat pumps. These systems absorb the heat from the house into the refrigeration lines and the heated gas is pumped outside. The fan in the outdoor unit passes air over the coiled lines to cool them down once more and bring the now liquid refrigerant back into the house. An air to air heat pump is able to reverse this process and absorb heat from the outside during those cold winter months, impossible as that may seem around these parts. If you are looking for an affordable way to keep your house cool in the summer, a Lennox air conditioner or heat pump will be the right fit for you.
