Learning What HSPF2 Is From Your Heating And AC Repair Professional | Mansfield, TX

Purchasing an energy-efficient heating and cooling system is every homeowner’s dream, considering that statistics have shown that these systems use a considerable amount of power. Are you planning to purchase and have a heating and AC repair technician help you install a heat pump? Then the unit you must check is the Heating Seasonal Performance Factor or HSPF. This measures how efficiently your heat pump will heat your indoor space in the cold season. However, the Department of Energy has refined the testing procedures for determining a unit’s HSPF, resulting in an updated measure; HSPF2. This is a more accurate scale for measuring the efficiency of your heat pump.

What Does a High HSPF2 Rating Mean?

From January 1st, 2023, the Department of Energy requires that all split heat pump systems have an HSPF2 higher than or equal to 7.5. All the single-packaged heat pumps should have an HSPF2 of at least 6.7. A higher HSPF2 rating means your heat pump will have higher energy efficiency. However, the right HSPF2 rating relies on several things, like the number of home occupants and your area’s climate. To determine the right heat pump to install at your home, consult your nearby heating and AC repair technician.

SEER2 vs HSPF2 Ratings

Regarding energy efficiency, heat pumps trounce other heating systems, such as furnaces, as they can transfer about 300% more energy than they can consume in ideal conditions. On the other hand, a high-efficiency gas furnace has an efficiency of 95%. Since heat pumps perform both cooling and heating functions, they can be a good investment for homeowners. Since heat pumps can cool and heat your home, they boast SEER2 and HSPF2 ratings under the new Department of Energy guidelines. SEER2 measures the heat pump’s energy efficiency during the cooling cycle, while the HSPF2 does the same during the heating cycle.

When you set the heat pump to “heat,” it distributes heat into your home, warming the air. HSPF2 measures your unit’s efficiency during this process. When it is set to “cool,” it extracts the heat from your home and dissipates it outside, cooling down your home. SEER2 measures the energy efficiency at this time. Hence, if you want an energy-efficient all-year-round heating and cooling system, you should talk to your heating and AC repair technician about installing a heat pump.

Differences Between SEER2 and HSPF2

Although both SEER2 and HSPF2 indicate the overall energy efficiency of the heat pump, they measure opposite things. SEER2 measures the energy efficiency of your unit during the cooling season, while HSPF2 measures the energy efficiency of your system during the heating cycle. As your heat pump can perform different functionalities, it needs these ratings to determine each function’s efficiency. If you live in an area that has extreme temperature fluctuations during the day and night, you should enlist a heating and AC repair professional to install a heat pump.

Which of the Two Ratings Is More Important?

More essential ratings vary based on the season. As mentioned above, HSPF2 measures the unit’s energy efficiency in the heating season, meaning it will be the most important in winter. SEER2 rating determines your heat pump’s energy efficiency in the cooling season. Hence, it will be more beneficial in the scorching summer months. Hence, if you live in regions that receive cold, wintry weather that lasts longer than the humid or warm temperatures, then the HSPF2 rating will be more critical. The reverse holds if you live in a balmy and hot place more than it’s frigid. Hence, a heat pump is the best unit to install a heating and AC repair pro, regardless of where you live.

How Much Money Can a Unit with Higher HSPF2 Help You Save?

Higher HSPF2 goes hand in hand with a higher SEER2, meaning a more effective system overall. If your heating and cooling system works smoothly, it can save you stress and time dealing with many issues. Additionally, it can help you save money. This is one of the main reasons it is recommended that you have a heating and AC repair company send someone for heat pump maintenance regularly. Additionally, having a higher-rated unit might cost you more initially than a lower-rated heat pump. However, the money you save on energy utility bills can justify the spending.

What Can Influence a Heat Pump’s HSPF2 Rating and Efficiency?


A heat pump “fits” your home. When installing them, the heating and AC repair professional tests and considers some factors to determine the right heat pump size to install at your home. This ensures that the unit can efficiently cool or heat your home based on its total square footage, number of floors, and how many rooms you have. A too-small heat pump will use more energy to cool or heat your home.

A too-large system isn’t better, either. It will cool or heat your home too fast and rapidly turn the process on or off to keep it at your desired temperature. This phenomenon is called short cycling and can make the heat pump use more energy than required, making it less efficient. To ensure you don’t install the wrongly sized heat pump at your home, consult your heating and AC repair technician.


The heat pump can heat your home in all outdoor weather. However, when the outdoor temperatures fall below 25 degrees Fahrenheit, it uses more energy to heat your home sufficiently. A properly-sized unit can heat your well-insulated home even if temperatures fall below zero. However, you could get better efficiency and comfort by having a heating and AC repair professional install a hybrid heat pump if you stay in an old home where temperatures fall below 25 degrees Fahrenheit.
