International Comfort Products brands such as Heil, Day & Night, and Tempstar offer 1-year, 3-year, 5-year, and 10-year unit replacement warranties and 10-year general parts warranties. Goodman, Rheem, and Ruud offer replacement of the unit if the compressor fails in the first 10 years. Unit replacement warranty: A few warranties offer replacement of the condensing unit if the compressor fails.Lifetime warranty: Some Goodman and Amana (a sister-brand of Goodman) models offer lifetime compressor warranties.12 years: The best models by American Standard, Trane, and Maytag offer 12-year compressor warranties.10 years: 10-year compressor warranties are the most common and are offered by leading brands such as Trane, American Standard, Carrier, Bryant, Lennox, Rheem, Ruud, Armstrong Air, and Heil.Cheaper air conditioners and base models from the Lennox Merit Series may offer this warranty. 5 years: 5-year compressor warranties are less common as manufacturers become more competitive with extended warranties.The labor costs to replace parts are not typically included in warranties if the unit is more than two years old, so you will likely have to pay for removing and installing the new compressor or unit. Some warranties will be voided if the condensing unit is not routinely maintained. It’s important to know what your warranty covers and its stipulations. Some warranties guarantee a replacement of the entire condensing unit if the compressor fails. A compressor is a vapor pump, and these compressors will seize up if too much liquid arrives at the inlet of the compressor.Compressor warranties differ among brands and range from 5 years to a lifetime. If you ever get liquid refrigerant back to your pump due to a dirty evaporator coil or dirty air filter, then it will cause significant damage to the internals of the pump. One thing to note is that a compressor does not compress the liquid. These are called water source heat pumps. Some compressors are cooled by water coils. These are compressors that are cooled off by a fan pulling air across your coils. Most everyone in Savannah, Georgia, has what is known as a vapor compressor. It’s being pulled out of the refrigerant within the condenser coils by the fan that blows the hot air out of the top of the condenser. The heat that was transferred initially from inside the home’s evaporator coil is now coming to the outside module. That heat transfer between that 110-degree air and maybe 150-degree air is called condensing. This process is known as the refrigeration cycle.Įven with our summer temperatures getting up over 110 degrees, the gas pressures from the compressor are high enough to cause the temperature of the freon to be so high that pulling the hot 110-degree air across the coil is still going to cool the refrigerant down enough to cause it to condense into a liquid. The freon’s heat is critical because the high-temperature refrigerant is so hot that the outside air will be cooler than the compressed refrigerant. The indoor coil absorbs the heat from inside your home versus pumping cold air into your home from outside. This is where it absorbs the heat from inside your house, and the refrigerant takes that heat back outside of your home. This high-pressure liquid refrigerant then travels through the suction line sets into the air handler’s indoor coil. Once your pump compresses the refrigerant vapor, it travels through the condenser coil and condenses the vapor refrigerant down into a liquid refrigerant. So your refrigerant and oils will naturally migrate to the warmer portion of the system. The heat transfer direction is from this higher temperature, high-pressure substance to a lower temperature, low-pressure substance, the lower temperature being the evaporator coil and the hotter temperature substance being the condenser. The pump is raising the pressures as well as increasing the heat. A high-pressure difference is needed for the refrigerant to flow correctly. The compressor increases the pressure of the refrigerant so that it reaches a pressure difference. The compressor is used to raise the temperature and pressure of the vapor refrigerant or gas, leaving the condensing coil through the discharge line.
