Each home has varying factors that need to be assessed to find the right size for your particular home and comfort level.
What does the yellow label on a heat pump tell you?
You have seen them. Bright yellow energy labels on a heat pump tell you the SEER and HSPF ratings. But what are SEER and HSPF ratings?
How does a heat pump work?
A heat pump is a central heating and cooling system that uses refrigerant to move heat from one point to another. In winter, a heat pump transfers heat from the outside air (air source heat pump) or the ground (geothermal heat pump) into your home while in the summer it reverses that process to cool your home.
What is HSPF rating?
An HSPF rating stands for Heating Seasonal Performance Factor and measures the heating efficiency of a unit. Like the SEER rating, this is an average standard based on a variety of conditions. The greater the rating the better the heat pump. When you look for efficiency ratings the higher the number the lower the energy consumption which is a win for your energy costs.

What is a heat pump?
A heat pump is an air conditioner that can also provide heat all within the same unit. Pretty awesome, right? A heat pump as an air conditioner takes in warm air from the inside environment (home, business etc.) and then disperses that warm air outside. It then disperses the remaining cool air into your home or business.
Why are heat pumps limited?
For producing heat, heat pumps are only effective at temperatures that are above freezing. But, why is this? Heat pumps are limited because of how they produce heat. Rather than creating their own heat, like a furnace does, heat pumps pull in warm air to use from the outside air.
Do furnaces have limitations?
Furnaces don’t have any limitations when it comes to delivering heat. It’s their main function and what they were created for. Remember, they create heat rather than simply passing on heat from the outside air. But, let’s get back to our focus here which is heat pumps.

Why Is a Level AC Unit Important?
When an air conditioner condenser is out of level, that puts excess stress on the unit. The fan motor revolves at high speeds, and a tilted motor can eventually be damaged by running at a tile.
What happens if the condenser is not level?
If the condenser is not level, then the air conditioner will have trouble working correctly. The pump inside the unit may not work the way it’s supposed to. The condenser pump contains some oil in the refrigerant that moves within the system, then returns to the pump. It’s possible for the oil to separate from the coolant and pool in one area of the condenser. When that happens the pump no longer has the lubrication it needs to function, causing a premature failure. It can wear out and overheat.
What happens if you move your AC unit?
If you try to move or level the AC unit yourself, you risk bending the coolant lines, causing a leak, and allowing refrigerant to escape into the atmosphere. Even a small kink in the copper tubing can cause catastrophe in your AC equipment. The leveling process is not a simple, one-size-fits-all process.
How to ensure condenser oil is moving smooth throughout the unit and not collecting in the compressor?
The one way to ensure the condenser oil is moving smoothing throughout the unit and not collecting in the compressor is to keep the unit level.
How much does a condenser weigh?

Advertisement. If the heat pump is low on refrigerant, the evaporation cycle is incomplete, and moisture in the air can condense on ...
Why does my heat pump freeze?
If the heat pump is low on refrigerant, the evaporation cycle is incomplete, and moisture in the air can condense on the evaporator coils and freeze. You can access the coils by removing the condenser cover, and if you find ice, you shouldn't try to remove it yourself because the coils are fragile and easily damaged.
How does a heat pump work?
When it's functioning as a heat pump, the outside coils are evaporator coils and draw heat from the outdoor air, while the inside coils are condensing coils, and they supply heat that gets circulated by the blower.
What happens if your heat pump is low on refrigerant?
If your heat pump runs low on refrigerant, the cycle will be less efficient, and the compressor will cycle on more often than it should. The end results are that your house doesn't get as warm, and your energy bill goes up.
How high should a heat pump be off the ground?
How high should a heat pump or air conditioner be off the ground? This will vary depending on your location. Normally it is recommended the system be 4-8 inches off the ground to provide adequate drainage and prevent snow buildup blocking the coil. In some areas, such as in a flood zone, the system may need to be much higher. It is common in some coastal areas for these units to be elevated on platforms several feet in the air.
How far off the ground should a heat pump be?
Ideally, the heat pump or air conditioner system should sit 4-8″ off the ground. However, often this is not enough because when contractors install the systems the area has not been landscaped. Landscaping around a system will reduce this clearance and can cause the base of the system to rust out if the base is covered by organic material like straw or mulch that holds water.
How does a heat pump work?
The most important factor in a properly working heat pump or air conditioner system is the flow of refrigerant and compressor oil through the copper tubing in the system. As the unit settles over time, the refrigerant and compressor oil can get trapped in the copper tubing and not flow freely through the system.
How many degrees should an air conditioner be level?
Heat pumps and air conditioners don't have to be perfectly level. It is acceptable to be within 10 degrees of being level provided it's positioned on stable ground or strapped to a raised platform. Severely unlevel units can cause long term problems with the fan motor and the compressor because of improper lubrication and vibration.
