Ductless Mini Split FAQ

 


Will an air conditioner with higher BTU cool my room faster?
BTUs determine how much cold air comes out of the unit, but problems can occur if the air conditioner is oversized for the space. The more cold air that comes out – the more area it needs to circulate to avoid giving the thermostat a false reading. If the unit is oversized, the cold air bounces off the wall back onto itself giving the thermostat a false reading – causing the compressor to shut off because the thermostat reads that the set temperature has been achieved. While the unit is off – the thermostat is able to read the room’s actual temperature, which kicks the compressor back on. This process will continue, causing the compressor to cycle off and on every two to three minutes, but never staying on long enough to effectively cool the room or remove uncomfortable humidity.
 

 
Could you explain the difference from between electric heat and a heat pump
When a unit says that there is electric heat there is a heat strip in the unit that uses the fan to distribute the heat. Electric heat is meant to subsidize an existing heat source. A heat pump function is similar to an air conditioner, however, instead of cooling the air like it would in the summer it heats the air and redistributes it into the room. It often will not work when it is colder than 40 degrees (except some PTAC and Ductless Splits) outside, but some units have electric heat backup. If heat is very important to you a PTAC or Ductless Split unit could be your best choice. Please look at the air conditioner description or call us at 1407-965-2133
 
What are EER and SEER Ratings?
The higher the Energy Efficiently Rating (EER), the more efficient the air conditioner. The EER of an air conditioner is determined by how many BTUs per hour are used for each watt of power. Air conditioners with a higher EER usually are accompanied by a higher price tag but cost less to run. Seasonal Energy Efficiency Rating (SEER) is commonly used to measure central and ductless air conditioning. All air conditioners must have a SEER rating of at least 10 to be sold in the United States. Air conditioners that are Energy Star have higher EERs and SEERs.
 

 

Do the systems come with installation kits?

All of our package systems come complete with line set, copper piping and all other accessories required for installation.  A multi-zone system will come with an installation kit for each air handler.  For example, a tri-zone system will come with 3 install kits.  Included with each kit is a 11, 16 or 25 foot length of line set that connects the indoor air handler to outdoor compressor. The 25' of piping can be extended by purchasing additional piping - flares - couplers etc. at home depot or any local plumbing supply store.  We also stock additional 16' extension kits if you want to splice 2 line sets together for a longer run.

 

 

Do I need to purchase tubing or add freon?

No, all our systems come packaged with a 15-25 foot line set.  These systems also come pre-charged with enough R-410A freon to extend the full length of the included line set.  You will only need to purchase additional tubing if the distance between the indoor air handler and outdoor condenser goes beyond the length of the line set that is included with the packaged system.

 

How much do they cost to run?

These energy efficient units provide localized cooling and heating for specified rooms of your home or office, rather than cooling or heating other areas that are not occupied. Since the air is cooled and released directly at the handler and doesn't travel through a duct system, the air does not loose any of it's coolness. This along with the localized climate control enables the ductless-split to operate the most energy efficient cooling system on the market. A 13 SEER efficiency rating is the base industry standard for mini splits - some advanced inverter units will feature SEER ratings in the 20-22 range.

 

 

How cold can the outdoor temperature be before I run into operation problems?

Standard 13 SEER units can operate in outdoor ambient temperatures from 18° - 109° Fahrenheit. However, it is important to remember that a heat pump may struggle to keep up with demand once outdoor temps drop below freezing.  If you live in extreme cold weather climates, you may want to consider an inverter DC system, supplemental heat or electric heat strips to make sure you have adequate heat for those cold winter nights.

 

 

How big will the hole in my wall be?

Generally, a hole 3" or less in diameter is all that is needed to run the refrigerant and connection lines from the outdoor condenser to the air handler mounted inside.
