Heat Pump vs. Air Conditioner: Which One is Right for Cooling Your Home Published on March 28, 2016 Although heat is in the name, you can use a heat pump for cooling. It works by transferring heat instead of making it (furnaces burn fuel to generate heat) which is why it is used as a dual function appliance. It's true that heat pumps can be very efficient, although most air conditioners are about equal in terms of SEER rating. Just look at these two luxury level cooling systems from Lennox. XC25 Air Conditioner up to 26 SEER ENERGY STAR® Qualified XP25 Heat Pump up to 23.5 SEER up to 10.2 HSPF ENERGY STAR® Qualified SEER is an efficiency guideline for air conditioners, and the larger the number, the better it is. The difference between 23.5 and 26 is not crazy however, and the efficiency differs depending on the model. On the other hand, HSPF is a different standard that stands for "heating seasonal performance factor" and is unique to heat pumps. It tells you how efficient the system is at heating. We can see from these examples that as far as energy effiency goes, air conditioners are mostly equal, if not superior depending on the AC you choose. The biggest difference between them is that heat pumps can also heat your home while an AC only cools. Heat pumps are much more effective in warmer climates with mild winters, save for some integrated systems that use heat pumps as backups or auxiliary, such as with a geothermal system. We recommend a consultation with a NATE certified HVAC tech who has experience in your city before getting your heart set on a heat pump. If the equipment just isn't right for your area, you could have extremely high electric bills. Once the temperature gets too low, it's much harder for the heat pump to draw heat out of the air and it may never warm your home to the temperature you set. This means you might start running your heat pump non-stop or switching on emergency heat 24/7 during colder months which drives your energy consumption up. How does a heat pump compare with a furnace? A furnace is a stronger heating system and is essential for certain colder climates. That’s because a heat pump has difficulty when the temperatures hit about 40 degrees Fahrenheit. As strange as it may seem, during heating season, a heat pump is purposed to pull heat from the outside air and use it to warm the inside air. Just because the air outside feels cold, there is still an adequate amount of heat for the heat pump to function well, but at exceptionally low temperatures there is not enough heat available outside to increase the inside temperature high enough to stay warm. So while a heat pump may be ideal during the heating season for someone in Daytona Beach, someone living in upstate New York with a heat pump may also need a furnace for the more extreme temperatures. If you’re living in those colder climates without a furnace to kick in during freezing temperatures, a heat pump may run for hours trying to make your home warm enough for comfort. In some areas, heat pumps can be used as geothermal systems, and the heating source is better for the environment as it is not burning fossil fuels and, instead, uses the Earth’s native temperature to heat and cool. This is a great alternative for particular northern climates, but more land must be available in order to install the necessary piping for a geothermal system. When it comes to home comfort, you probably didn’t need anything else to think about; but, remember, it’s important to review the pros and cons of each heating and cooling system so you don’t end up investing in a system that shuts down when extreme temperatures hit, or investing in additional systems when one would suffice.
