FAQs

  1. Why should I choose Trane heating and air conditioning equipment?
    Increased comfort, efficiency and reliability are the main reasons for choosing a new Trane heating and air conditioning system. Trane's split system cooling units and heat pumps all have fully louvered panels to protect the outdoor coil from damage, as well as Powder Paint finishes and weather resistant screws. Trane is the only manufacturer to offer all aluminum outdoor coils, the patented Spine Fin coil which provides greater heat exchanging capabilities, thus higher efficiencies, and greater resistance to corrosion than traditional copper / aluminum coils. Trane is the obvious choice because of their gas furnaces' self-diagnostic controls, a heavy steel 40" high, insulated cabinet, hot surface igniter, multi-port in-shot burners, one piece heat exchangers with no welds, durable pre-painted finish, and some of the highest efficiencies in the industry. Trane is also the variable speed airflow experts. Our variable speed furnaces and air handlers can do things other manufacturer's products can't, such as humidity control with Comfort-R Enhanced Mode. This feature allows the furnace blower to slowly ramp up, slowly ramp down, or to operate a 50 percent of cooling speed in the FAN ON position. This provides greater air circulation , air filtration, even temperature distribution, humidity control, and quiet performance. Variable speed motors are the most efficient motors as well, increasing the efficiency of your heating and air conditioning system. Trane products can be reviewed on their website at www.Trane.com.

  2. What do all those rating numbers mean?
    The federal government requires all air conditioning and heating equipment to be rated for efficiency. The higher the rating, the more efficient the model. Gas furnaces are rated for AFUE (Annual Fuel Utilization Efficiency). This defines the amount of heat used to warm your home from the burned fuel. A 90% furnace will use 90% of the available heat to heat your home. 10% of the heat is vented outdoors. Many older gas furnaces are only 60% efficient. The other 40% is vented outdoors. You can see that a new high-efficiency furnace will require much less fuel to heat your home. For air conditioning, the rating is SEER (Seasonal Energy Efficiency Ratio). This rating is based on general design criteria such as the compressor and outdoor coil. SEER ratings are for comparison purposes only, so that homeowners will know how they can compare different brands of products with similar efficiency ratings. The rating for the outdoor unit will reference a general efficiency range, such as 14 SEER. The actual efficiency rating for a specific system will depend on the combination of the outdoor unit and the indoor coil. A variable-speed indoor blower unit will increase the efficiency rating of the system as well.

  3. Should I cover my outdoor unit?
    Covering the unit is not necessary. Air conditioners are manufactured to withstand all possible climate changes. In fact, rain helps keep your unit clean. Of course, because heat pumps run all year long, they should never be covered.

  4. How close to the outdoor unit should I plant shrubs or flowers?
    Manufacturers generally agree that plants should not be closer than 18 inches. Air conditioners need intake and exhaust air to operate efficiently. If air cannot circulate, the unit could build up heat and require service.

  5. What are the average life expectancies for heating and air conditioning equipment?
    The average expected life of an air conditioner is approximately 15 years. The average expected life of a gas furnace or air handler is approximately 18 years. Units in corrosive environments, such as, but not limited to coastal installations, will tend to have shorter lives.

  6. Why do my lights flicker when my air conditioner turns on?
    Light flicker associated with the starting of appliances usually does not pose any safety problems and does not damage appliances. Proper wire connections and grounding are necessary to reduce flicker. Contractors and homeowners should check with their local utility regarding the appropriate wire size and transformer servicing the home. In cases where light dimming is related to the starting of a central air conditioner, and the previously discussed steps have not resolved the situation, manufacturers offer start assist kits that can be purchased which may help reduce flicker.

  7. Why does the air from the register feel cool when my heat pump is set for heating?
    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. The air is heated to about 90 to 95 degrees, depending on the outdoor temperature. This temperature is approximately 20 to 25 degrees warmer than the indoor air temperature and will warm your house. It is, however, below body temperature (98.6 degrees) and can feel cool when someone puts their hand in the airflow.

  8. Will anything help control the humidity in my house?
    Humidity is a problem in many areas. The best way to control excessive humidity is to have a system that runs longer at lower speeds. Variable speed air-handling equipment runs at very low speeds, which keeps the air circulating against the cooling coil and removes much more moisture than conventional systems. At these low speeds, the variable-speed motor also uses much less electricity than conventional motors.

  9. What services need to be performed for preventative maintenance on my heating and air conditioning equipment, and how often should this maintenance be performed?
    We recommend you have your local independent Trane dealer perform preventive maintenance before the winter heating season and before the summer cooling season. Many local independent Trane dealers offer service agreements that may include reduced rates on labor and parts and provide priority response. Service/maintenance agreements may include cleaning indoor and outdoor coils, tightening electrical connections, checking supply voltage and operating current, checking refrigerant charge, measuring temperature differential at supply and return registers, cleaning blower wheel and motor, inspecting and adjusting burner, checking heat exchangers, cleaning drain lines and pan, checking ductwork for leaks and insulation, and checking thermostat.

  10. Do I need to think about the new refrigerants when buying a system?
    We do not advise homeowners to choose home comfort systems based on the refrigerant they use. The Clean Air Act does not allow ANY refrigerants to be vented into the atmosphere. They must be reclaimed, recycled and reused. Units using the current refrigerant, R-22, will always be serviced with R-22. They will not need to be changed to a different refrigerant. The scheduled phased-out of R-22 allows for plenty of refrigerant to be available to service all cooling units and heat pumps that use R-22 for the life of the equipment. We do offer limited lines of high efficiency comfort systems using R-410A refrigerant. Our gradual introduction of these products will allow servicers in the field the opportunity to purchase new recover equipment and service tools, as well as adapt to stricter installation and service techniques, to insure homeowners continue to receive the comfort and value they have chosen. As the HVAC industry gradually and confidently transitions to a new refrigerant, we encourage homeowners to maintain their focus on purchasing energy efficient home comfort products that best meet their comfort needs.

  11. What are the differences in Trane's single, 2-stage, and Variable Speed Gas Furnaces?
    A single stage furnace will deliver the same amount of heat and airflow no matter what the temperature outside. A 2-stage furnace with a 2-stage thermostat will begin in first stage (low burner, low airflow) and only go to the second stage if the indoor temperature drops during first stage. This makes the furnace run longer, providing greater air circulation, temperature distribution, and air filtration. This also provides more consistent comfort. The second stage will only come on when the need is there and then it will be able to run longer and maintain the comfort level. The more your system starts and stops, the less comfort you will have and less efficiency due to duct heat loss. The advantage of Trane's 2-stage, variable speed furnace is it has Comfort-R(trademark) Enhanced mode. This allows the blower to slowly ramp up and ramp down or operate at 50 percent of the cooling air speed in the FAN ON position. This provides greater humidity control, quieter operation, and maximum air circulation, temperature distribution, and air filtration.
