Point of Reference

Trane Air Handler

 

 

Air Handler – This is the indoor unit that blows the air into the house. It contains the indoor coil, the heat strip, the air filtration, the blower assembly, the refrigerant metering device (TXV) and the condensate drain. Options include: a metal or composite cabinet, a single or variable speed blower motor, copper or aluminum coils, mechanical or electronic refrigerant controls and a communicating (smart) or non-communicating system.

 

Air Handler Blower Speeds – Single speed blower motors are only able to run at one speed, no matter what the demand is on your system. For instance, it would be like driving a car that could ONLY go 100 mph. Variable speed blower motors are able to adjust air speed based on system demand, humidity, temperature, etc. Not only does they allow for better humidity control, but variable speed blowers also use much less energy.

Trane Media Filters

 

Air Filtration – We offer many different types of air filtration, all of which are designed for different purposes. UV filtration is used to control and prevent biological growth. Mechanical filtration is used to filter out dust, pollutants and particulates. Mechanical filters include standard 1”, 5” media and Trane CleanEffects. For the best filtration results, mechanical and biological filters should both be used.

 

Compressor Speeds – Compressors come in four variations:

  1. Single speed: This is only able to run at one speed all the time.
  2. Two-stage: It’s able to run at two different speeds.
  3. Two compressor: It has two compressors that will run either independently or simultaneously, according to demand.
  4. Variable Speed: This is a 700-speed compressor that allows control up to 1/10 percent. Simply put, more speeds means better efficiency, better humidity control and better air filtration because of longer run times.

A/C Drain Line

 

 

Condensate Drain Line – This is the PVC pipe that carries the water (humidity removed from inside your home) from the air handler to the outside of your house. Similar to refrigerant lines, we always recommend replacing the drain line when possible, because PVC becomes brittle with age. We have also seen fittings that were not properly glued or piping run without proper slope. Because of this, we cannot warranty condensate lines that we did not replace.

 

 

Condenser – The outdoor unit that acts as the heat exchange. The condenser contains the outdoor coil, compressor, fan motor and reversing valve if it’s a heat pump. Options include: composite base pan, spine-fin coil, compressors speeds, noise levels and durability.

Cooling Ton (Capacity) – This number simply indicates the size of the system. Correct equipment sizing is imperative for proper system operation. Load calculations are performed to ensure the proper tonnage. For reference: 12,000 BTUs = 1 ton of cooling capacity.

Straight Cool vs. Heat Pump – Straight cool units (air conditioners) are only able to heat your home with an electric heat strip located within the air handler. Heat pump systems are equipped with a reversing valve that allows the refrigerant to run in “reverse” to allow the indoor coil to heat your home. Heat pumps are able to heat your home more energy efficiently.

 

ducts

Ductwork – This is your home’s insulated air delivery system for the air conditioning system. Think of it as arteries for your heart. Even if you have the best air conditioning system on the market, it will not work if your ductwork is not properly set up. For this reason, we often recommend duct replacement, repairs or additions when you purchase a new system.

 

Refrigerant Lines – These are the copper lines that carry refrigerant between the air handler and the condenser. We always recommend replacing your copper refrigerant lines when replacing your system, because copper deteriorates over time, causing leaks. New refrigerants also operate at higher pressures, and, as a result, can cause new leaks to develop. For this reason, we cannot warranty refrigerant lines that we have not installed.

SEER Rating – Seasonal Energy Efficiency Ratio. Higher SEER means less energy usage. Think of it like miles per gallon for a car.

Thermostat – This is the device that controls your system. Choices include: programmable vs. non-programmable, internet connected, app controlled, zone control capability, humidity control, etc.

Zoning – Sometimes it’s best to “zone” your house to best fit your use. This allows you to only cool the parts of your house that you use most. For instance, you could keep your bedroom/bathroom at 74 degrees, the living room at 78 degrees and the guest room that barely gets used at 80 degrees. This allows you to greatly reduce your energy consumption.
