Troublefree Inc. understands that you have questions. Here are some of the most common questions that are asked.

• What does BTU stand for?
• British Thermal Unit. This is the amount of heat it takes to raise one pound of water one degree Fahrenheir.

• What does SEER stand for?
• Seasonal Energy Efficiency Ratio.

• What is the difference in the SEER numbers?
• Put simply the higher the SEER number the more efficient the unit and the less it costs to operate.

• How can I find out what size my existing unit is?
• The capacity in tons of the outdoor unit can be determined by dividing the 7th and 8th digit of the model number by 12, such as 4TTX4036A1000A - 36 divided by 12 = 3 tons.

• Why is the size of the unit important?
• A system that is too large will cool or heat your house quickly, but you still may not feel comfortable. That's because it will satisfy the thermostat before it can adequately remove sufficient moisture from the air - which will in summer feel stickier than it should be. And, the stress of short-cycling (too many starts and stops) will shorten the life of your equipment and increase your heating and cooling bills. On the other hand, a system that is too small just cannot get the job done. The air conditioner will run constantly in the summer and the furnace will do the same in winter. Your dealer will determine the correct system size needed for your home by doing a room by room load calculation. This heat loss/heat gain analysis is the best indicator of the correct system size.

• What is a package unit?
• A package system is a self contained unit that sits outside next to the house or on the roof as is the case with many businesses. There are both gas packs and packaged heat pumps.
