Air conditioners are some of the most expensive pieces of cooling equipment you can purchase. This fact alone makes the need for air conditioner repair more important. There is such a difference in the quality and technological features of every air conditioner, that it’s important to carefully research each individual model in order to determine which will best suit your needs. Luckily, there are many ways to tell if a unit needs replacement or repair; there are specific signs that indicate when a unit’s condition is deteriorating and when repairs are needed.
One sign that indicates that a unit’s condition is deteriorating is if it produces an unusually high amount of heat or cold air. Low energy efficiency and increased operating costs are a leading cause of this problem. Another common sign that air conditioners need maintenance is the frequency in which the coolant needs to be changed. If the coolant is not changed on time, it can lose its refrigerant effectiveness and quickly lose its ability to keep the unit’s temperature regulated. If the temperature of the cooled air in your home falls below the desired levels for comfort, this can lead to the conditioner’s efficiency and effectiveness reducing over time.
One of the most obvious signs that air conditioners need replacement or repair is a noticeable drop in their energy efficiency. Energy efficiency refers to how much heat and cool air is produced by the machine. If the unit is producing too much heat or too much cool air, it is obvious that some of the ducts need to be replaced. It is also important to note that too little heat or cool air can cause the unit to produce less than optimal temperatures and may actually cause the unit to overheat. The more heat that is produced, the more expensive the unit will be, but in the end the extra cost is often worth it because it means a more comfortable home.
Another sign that you may need a repair or replacement is an energy efficiency rating. Energy efficiency ratings are based on measured outputs of electricity, and they are usually measured in kilowatts per hour. A energy efficiency rating is determined by using historical data on average temperatures in the local climate. Some units have been developed to better simulate outdoor conditions so that they can also reduce the amount of air conditioning needed in dry climates. If the unit is producing too many cold air hours, it may not be an appropriate cooling system for your area.
If your air conditioner is not operating properly in your current climate, it could be an indication that it needs to be upgraded to a more effective model. Different climates have different kinds of air flow and their own unique cooling needs. Some types of air conditioners are best suited for dry climates while others may not be able to cool as well in humid climates. A more powerful air conditioner can also help lower the humidity in your home. It may be a good idea to get an air conditioner with a higher maximum temperature for dry climates and a lower one for humid climates.
One last sign to look for when checking your air conditioner is if it has a humidity sensor. The Ashrae recommends that the humid climates of high humidity should have a humidity sensor that is located outside of the house, preferably in an obvious place. Humidity sensors can often find leaks in the walls and ceilings, which is why the Ashrae recommends that it be located in an inconspicuous spot. This way, the sensor will not trigger an alarm in case there is a leak in the ductwork.
