Heat PumpsWhat is a heat pump? Just think of a heat pump as an air conditioner with a "Reverse" gear. A heat pump does two jobs, but it uses the same principles for both. On warm days, it works exactly like a regular air conditioner. It extracts heat from inside your home and transfers it to the outdoors. On cold days, it does just the opposite, pumping heat energy from the outdoors into your home. How can the machine pump heat out of cold air? Because the system's refrigerant evaporates at such low temperatures, drawing heat from the surrounding air. Strange as it may seem, even if it's freezing outside there's still enough heat energy in the chilly air for a heat pump to warm your home. Of course, the colder the weather, the more difficult all this heat-transferring business becomes. So air handlers (the indoor part of a heat pump system) have supplemental electric heating that kicks in when the temperature is extremely low. This makes a heat pump a more-than-adequate heating system for homes in all areas of the country. In the colder parts of the country, some heat pump owners prefer to have a gas furnace to run on the most frigid days. What should I look for in a heat pump? Quality Efficiency HSPF (Heating Seasonal Performance Factor) which means that there is an outdoor unit (condenser) and an indoor unit (coil) . If you’re replacing an existing system, both units should be replaced to make sure your new condensing unit gives you optimal performance, efficiency and comfort. Note: Air-source heat pumps — the type most commonly used in homes — are typically installed with additional back-up heating (usually electric resistance strip heating) for days when the outdoor temperature drops below 30 and the heat pump cannot extract enough heat from the outside air to heat the home. SEER and HSPF ratings do not refer to the efficiency of electrical resistance backup heat, which is calculated differently.
