When we called tech support at Goodman Manufacturing (maker of both Goodman and Amana air conditioning systems) to find out what the acceptable tolerance was for leveling a heat pump or air conditioning condenser, the answer we got was “level means level.” They did not offer any range of deviation for a condenser to tilt and still be acceptable.
What happens when a condenser is out of level?
How far should a condenser be clear?
How high should a pad be above ground?
How level should AC condenser be?
To function at their best, air conditioners and heat pumps must be positioned on level ground. AC equipment can malfunction or wear out prematurely if the ground beneath them shifts or tilts more than a few degrees.
Do AC condensers need to be level?
The first and most important reason that the condensing unit must be level has to do with the oil in the compressor. In an air conditioner or heat pump, refrigerant circulates through lines and coils, transferring heat into or out of the building, depending on whether you're heating or cooling.
Does a compressor need to be level?
If the compressor is not level: It will compromise its efficiency, and it may not work as effectively. The system contains oil to lubricate the motor. A small part of the oil runs through the system and returns to the motor.
Are AC units supposed to be tilted?
DON'T forget to measure the unit's tilt. Many window units require a very slight tilt away from the building to keep condensation in the drip pan outside the room, rather than puddling down the wall inside your home.
How do you level an AC condenser pad?
Try working a long board under one end of the concrete air conditioning pad, lifting it up, then packing sand under it. Do the same on the other end of the concrete air conditioning pad, making the pad as level as possible. Lift the concrete air conditioning pad slowly to avoid cracking it.

How does refrigerant work in an air conditioner?
Refrigerant, along with lubricating oil, travels through your air conditioner’s compressor, allowing your unit to cool the air in your home. If your condenser unit has not been installed levelly, it will be difficult for the refrigerant and oil to easily travel through your system, causing tremendous strain on your compressor and increasing the likelihood of a unit malfunction. It is imperative that you ensure that your AC unit is always level to avoid refrigerant back-ups.
Why is my air conditioner drip pan leaking?
One of the unsung heroes of the air conditioning unit is the drip pan. Your drip pan collects excess moisture produced by your unit and prevents it from leaking into the unit itself or the surrounding area. However, if your condenser is not level, it becomes very easy to experience drip pan leaks. These leaks are problematic due to the fact that too much moisture in your unit can cause serious levels of damage—not to mention the mess it can cause in the area directly surrounding your unit. Having a perfectly level condenser ensures that your drip pan functions properly and keeps the repairman away.
Can an AC unit break down?
It is possible, in the short-term, for your air conditioning unit to function while not being level. This fact may lull you into a false sense of security, which is why many people tend to ignore the problem. Long-term, however, your condenser unit can develop very serious issues that may cause it to break down at the worst possible time. When your unit is unevenly installed, it will vibrate every time it is in use. The effects of this vibration will build up over time and result in damage within your unit that you won’t be able to see until it’s too late. Ensuring levelness during your Tempe AC unit install will guarantee that your air conditioner stays running smoothly, well into the future.
Is it necessary to have an air conditioner in Tempe?

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.
Why Is a Level AC Unit Important?

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.
What is leveling a heat pump?
Part of leveling a heat pump or air-conditioning system involves addressing the problem that originally caused the situation in the first place. This may mean replacement of the pad, repositioning the pad or elevating the system off the ground entirely by building a raised platform for the system to sit on.

How far should a condenser be clear?
Typically, a minimum of one foot clear around the sides and five feet above it is specified. Also, installing a condenser at an inside corner is not recommended because of the reduced natural air circulation.
How high should a pad be above ground?
A mounting pad elevates the base of the unit a minimum of three inches above the ground at installation and, unfortunately, the settlement is often accompanied by the pad sinking into the dirt. The minor vibration generated by a condenser, combined with its weight, creates a low-energy, but repetitive tamping action that can slowly ease the condenser pad into the soil a little over time.
