Travis Crawford Heating and Cooling, Inc.

Equipment Replacement

Air Conditioners, Gas Heating Systems and Heat Pumps  

When it comes to new air conditioning and furnace units, Travis Crawford Heating and Cooling will install and service the brand of your choice. Air conditioning and furnace unit replacement is available for any make or model.

We’ve provided some basic information and terminology on three major forms of HVAC equipment installation that we provide.  This is, of course, only a handful of the different HVAC equipment that we install.  If you have any questions, please call us at any time.  We are always glad to help.

Gas Heating Systems: 

  • Understanding 80% and 90%-95% Efficiency Units: In an 80% efficient system, gasses are hot enough that they need to vent conventionally into the chimney stack. In a 90%-95% efficient system, the gasses are much cooler and vent to the outside via an exhaust vent, much like a clothes dryer.
  • AFUE (Annual Fuel Utilization Efficiency): Indicated as a percentage, your furnace’s AFUE tells you how much energy is being converted to heat. For example, an AFUE of 90 means that 90% of the fuel is being used to warm your home, while the other 10% escapes as exhaust with the combustion gasses.
  • Combustion Air: Combustion air is the air required to properly burn the gas for your heating system to get maximum capacity.
  • Heat Exchanger: This is the part of a furnace that transfers heat to nearby air; the chamber where fossil fuel is burned. An improperly sized heater will cause expansion and contraction of the heat exchanger, which will lead to premature aging and cracks.
  • Venting Types: Your new gas heater will vent the combustible gasses in one of two ways – via a direct vent system or into an existing chimney. In most cases, the chimney will need to be relined in order to generate the correct draft.
  • Single-Stage Gas Valve: Single Stage Gas Valves operate on a basic on/off principle. Each time your themostat calls for heat, your heating system comes on at 100% capacity.
  • Two-Stage Gas Valves: Two-Stage Gas Valves are capable of two levels of operation — a low stage and a high stage. Properly sized equipment will operate 60-70% of the time in low stage, enhancing energy efficiency and comfort with perfect humidity levels and quieter operation. It’s like getting two heaters in one.
  • Standard Blower: A standard blower delivers a specified amount of air flow based on a tap setting.
  • Variable-Speed Blower: This high-efficiency blower is designed to deliver a varying amount of air flow based on the desired outcome. These blowers increase the effectiveness of humidification, dehumidification, air filtration and balance of air flow
  • Humidification: This is the process of adding moisture to the air by using a whole house humidifier. During the winter months, heated air can make your house too dry. Adding moisture protects your furnishings and reduces static electricity. Coupling a humidifier to a variable-speed blower gives you the ability to manage your humidity to the exact level you would like.
  • Indoor Air Quality: This refers to the cleanliness and healthiness of the air in your home. Many factors affect air quality: smoking, pets, location of the property, age of the home, tightness of the house, etc. Perhaps the biggest enemies of indoor air quality are allergens – microscopic particulate matter, bioaerosols and volatile organic compounds that can produce allergic reactions, impede breathing or make you sick. Dust, pollen, germs, mold, and chemicals – all can be in the air. The wrong heating system can house, spread and recirculate these allergens.

Air Conditioners:

  • SEER: SEER (Seasonal Energy Efficiency Ratio) is the measure of efficiency by which the cooling process of air conditioners and heat pumps is rated. The higher the SEER rating, the greater the efficiency – and therefore greater energy savings.
  • Single-Stage Compressor: Single Stage Compressors operate on a basic on/off principle. Each time your thermostat calls for cooling, your air conditioning system comes on at 100% capacity.
  • Two-Stage Compressor: Two Stage Compressors are capable of two levels of operation, a low stage and a high stage. Properly sized equipment will operate 80% of the time in low stage, enhancing efficiency and comfort with lower humidity levels and quieter operation. It’s like getting two air conditioners in one system.
  • Refrigerant: R-410a (also known as Puron) is an environmentally-sound refrigerant designed to not harm the earth’s ozone layer. Federal law requires that all manufacturers phase out R-22 (better known as Freon) and other ozone-depleting refrigerants in the next few years. R-410a refrigerant is approved by the US Environmental Protection Agency as a replacement for R-22.
  • Dehumidification Mode: The process of varying air flow and compressor operation can allow certain air conditioning applications to manage exact indoor humidity levels.

Heat Pumps: 

  • HSPF: The Heating Seasonal Performance Factor is a measure of the heating efficiency of a heat pump. The higher the HSPF number, the more efficiently the heat pump heats your home.
  • SEER: SEER (Seasonal Energy Efficiency Ratio) is the measure of efficiency by which the cooling process of air conditioners and heat pumps is rated. The higher the SEER rating, the greater the efficiency – and therefore greater energy savings.
  • Refrigerant: R-410a (also known as Puron) is an environmentally-sound refrigerant designed to not harm the earth’s ozone layer.

  • Dehumidification Mode: The process of varying air flow and compressor operation can allow certain air conditioning applications to manage exact indoor humidity levels.
  • Electric Heat Staging: The ability to bring the electric back-up heat in stages as opposed to coming on all at once.
  • Indoor Air Quality: This refers to the cleanliness and healthiness of the air in your home. Many factors affect air quality: smoking, pets, location of the property, age of the home, tightness of the house, etc. Perhaps the biggest enemies of indoor air quality are allergens – microscopic particulate matter, bioaerosols, and volatile organic compounds that can produce allergic reactions, impede breathing or make you sick.
