The upper unit plug-in has not changed in over 20 years. It is compatible with almost all lower unitsBy tommyAnswer: On a coleman, that's all there is to it! As we approach the height of summer, household central air conditioners are beginning to really get a workout. Keeping the A/C on helps keep you comfortable, but it can also become expensive. That's why it is so important to make sure your system is running well. cost to run ac all dayIf you find that your A/C system running constantly is driving up your bill, then it's time to look into the cause. There are numerous reasons why your A/C system may seem to be running non-stop throughout the summer. The truth is, this may not always be a bad thing. Some of the reasons below may indicate a problem with your system and others may alert you to other issues in your home that you can take steps to correct. It's important to start our discussion with this fact: a properly sized, energy-efficient central air conditioning system will run fairly continuously in the summer to maintain a constant, desired temperature in your home.

These systems operate at their highest efficiency level when allowed to do their job at "full tilt." Unit Too Small: If your central air conditioner is too small, then it is going to have to work harder to cool your home. Over time, this will increase the wear and tear on your unit and reduce its life. You will also never achieve the desired coolness in your home, even though the system runs often. In addition, breakdowns will be likely. Unit Too Large: If your system is too large, it won't effectively remove moisture from the air in your home, resulting in an output of moist, clammy air. It will actually have shorter run times than it should and use excessive amounts of electricity, resulting in higher utility bills. Wrong Duct Size: The size of your ductwork should be relative to the size of your air conditioning unit.  If your ducts are the wrong size, they may not be able to handle the airflow or distribute cool air efficiently to all parts of the home. If your system seems to never shut off, there may be an issue with your thermostat.

It may be that your home has reached the correct temperature, but the thermostat is not registering the conditions in the home. In this case, your A/C unit will continue running. One way to check the thermostat is to place another thermometer near the location of the thermostat. After an hour or two, check the reading. If it is at or near your desired home temperature, there may be a problem with your thermostat. Poor sealing or insufficient insulation is another common culprit which can cause your unit to run constantly and inefficiently. If your home is not closed up tight while your A/C system is in use, you may be losing that precious cool air that you need during the summer through small holes or non-insulated walls or roof. If you are losing the cool air in this way, your home may never reach your desired temperature, causing the A/C unit to run more than needed. Our related blog post here gives you some background on why sealing and insulating your home is so important, especially for A/C efficiency.

Air conditioning units need regular maintenance to continue running smoothly, much like other appliances in your home. Ideally, maintenance should happen twice a year, in the spring before the warm weather hits and in the early fall after things have cooled off and it is no longer in use. If your system is not clean, including your ducts, coils and air filter, you will likely encounted airflow problems and inefficient cycling. A professional technician will check to make sure everything is clean and lubricated. He/she will replace worn parts and confirm that the thermostat is working properly. Regular maintenance of your A/C unit will not only help ensure that your unit is in good working order, it will also extend the life of your cooling system. Air conditioners have a life span. Even if your unit has been properly maintained, it will eventually wear out. At this point, you may want to consider replacing your old, inefficient unit with a new one. This will save you money in the long run, because newer units run much more efficiently than old ones.
