For a basic cooling air-conditioner, its purpose is to supply the cool air to the room. In the particular refrigeration circuit, refrigerants circulate in the equipment repeating the processes of compression, condensation, expansion and evaporation and back to compression in order to remove the warm air inside refrigerant device by using a four way valve to reverse the flow of the refrigerants. In the reversed cycle,

The capacity in tons of a Trane outdoor unit can be determined by dividing the 7th and 8th digit of the model number by 12. So if the model number is 4TTX4036A1000A, take 36 and divide by 12, equalling 3 tons. This is only for Trane models. Other companies use a different method based on their model number nomenclature. While a heat pump is perfectly capable of effectively heating your home, the temperature of the air coming out of the registers confuses some people.

In the summer, a heat pump works in exactly the same way as an air conditioner, i.e., cooling your home or office by moving heat from the inside to the outside. In the winter, a heat pump operates in “reverse”, moving heat from the outside to the inside of your home or office. Even though it feels "cold" outside during the winter, there is still plenty of heat in the air that can be captured by a heat pump.

SEER (Seasonal Energy Efficiency Ratio) is a system for rating the efficiency of cooling equipment. The higher the SEER rating, the less your unit will cost to operate. HSPF (Heating Seasonal Performance Factor) is a measurement similar to SEER, but it measures the efficiency of the heating portion of a heat pump.

Our XLi outdoor product lines have higher air conditioning efficiencies (SEER) ranges than the XB line. Some of the enhanced features include Trane's patented WeatherGuard? top that provides maximum protection for the outdoor condenser coil, a compressor sound enclosure for quiet performance, a two-speed condenser fan that improves both efficiency and sound levels, and twice the original limited warranty as the XB outdoor product line.

Most heating and cooling systems manufactured today are quieter than those produced in past years. But there is still significant variance in sound rating ratings among these products. Lennox designs each air conditioner and heat pump to be as quiet as possible. Through extensive testing, Lennox has come up with many features that, either alone or in combination, make our air conditioners and heat pumps some of the quietest available.

The industry sound rating numbers are complicated and often difficult to understand. Sound rating is just one of these areas. A difference of 6 decibels (such as between 72 dB and 78 dB) is technically a four-fold increase in compressor sound when rating air conditioners or heat pump units. However, it takes a difference of 10 decibels to double the loudness. It is also noted that it takes approximately 3 decibels for the average human ear to discern any difference in loudness at all.

Air conditioners work by transferring heat from inside your home to outside, effectively lowering the indoor temperature. Heat pumps work exactly the same way in the summer, but in the winter they can reverse the temperature exchange, providing one of the most efficient forms of heat available.

If you have a system that has been properly sized for your home and you keep it properly maintained, it should last as many as 15 years with minimum problems. But if the size is incorrect or the unit is maintained only when it breaks, the lifetime can easily be reduced by five or more years.

A 12 SEER heat pump and a 12 SEER air conditioner would cost the very same to operate during the cooling season. There is no difference during the cooling months.

This top of the line thermostat is compatible with virtually all units on the market. Yes, it does. If you have an electric water heater, we will install a Demand Conservation device and pay you $2 per summer month (June through September) per water heater.

The unit could be taking on too much water. At the back of the unit in the bottom left corner there is a rubber tube. Open the tube and drain the water. Press the reset button and start the unit. The unit will run for about 15 minutes before the compressor kicks in. If the unit still does not cool, take it to an authorized service centre.

This is a supplemental source of heat provided by a resistance element inside the A/C unit. Basically it is a strip of wire that heats up when electricity is applied. These will generally take the chill off of your pop up, but should not be counted on as your only heat source in cold climates. The only things you really need to worry about with the air conditioning unit is where the condensation water will run off to and remembering to clean the filter.

Many factors affect the cost of a heating or air conditioning system, including the size of your home, the type and condition of the ductwork installed, and accessories you might need such as a thermostat or an electronic air cleaner. We have a complete range of systems and accessories available to meet all your needs, including your financial ones! Your local dealer will be happy to assist you in finding the right system to meet not only your comfort needs but also your household budget.

Yes. Supplemental electric heat is available on most EMI systems (factory installed only). Check the specific evaporator specifications for all available options. a reference guide please refer to the SIC condensing unit specification sheet to compare the capacities of the other manufacturer’s unit to an EMI unit (bulletin 01010). EMI will not warrant use of EMI heat pumps with other than approved EMI evaporators.

No. Many minor service problems can diminish the cooling process such as a dirty filter, outdoor condenser, and indoor evaporator coil. Another cause could be caused by a leak in the system. It is advisable to have a service technician evaluate the systems performance and either repair the system or recommend a replacement or upgrade if it is a more expensive repair.

It could be as simple as replacing a fuse, resetting a circuit breaker or checking to see if the thermostat is set properly. If an electrical problem isn't the cause, the refrigerant may be low if the system still runs but does not cool properly. This can be corrected by having an EPA certified technician add necessary refrigerant.

This is not generally recommended since the moisture added to the air could condense when it comes in contact with the very cold air conditioning coils. You will likely not need supplemental humidity during the summer months anyway.

No, an air conditioner lowers the temperature of the air and thereby removes the moisture as well, so any humidity entering the system is immediately removed by the air conditioning coil. At the end of the heating season, the humidifier should be shutdown in accordance to the procedures as outlined in the instruction manual.

If your Heat Pump appears to under perform - the first thing to try is cleaning the filters with your vacuum cleaner. These need to be cleaned once a fortnight. Simply by cleaning the filters can make a huge difference.

Push the small button marked auto/cool located under the cover plate for the wiring on the indoor unit. This is a manual switch that can be used if the remote is lost or not working. The button may have been pushed once by mistake to put the unit into auto mode and by pushing it again it will switch over into cooling, you can also turn the unit off and on again and then push the button if it does not work the first time.
