We all count on our air conditioners to keep us cool. However, the unit itself can overheat while it’s creating comfortable conditions for you. What causes overheating when the AC is on? Dirty components and faulty parts are common culprits behind this common issue. If the air conditioner unit is overheating, rely on the top-rated AC service in Medfield, MA, to fix the problem quickly.
Learn more about the different issues that can cause overheating when the AC is on and when to call in the professionals.
Refrigerant Leak
Air conditioners rely on refrigerants to cool the air in your home. A refrigerant link could leave the AC unit unable to reach the temperature you set on your thermostat. The refrigerant cools the air before the system pushes it through your home or business. If you don’t have enough refrigerant, the air inside your home feels warmer, and the AC unit’s components can overheat.
An air conditioner repair tech can measure your unit’s refrigerant level. If it’s low, the tech can look for signs of a leak in the system. After fixing any leaks, the tech can add more refrigerant and have the system running normally. Only a professional HVAC technician should refill the unit with refrigerant.
Poor Installation in Medfield, MA
Your Medfield, MA, air conditioning unit needs a proper installation. If you purchase a home or business and later notice the air conditioner overheating during normal operation, the original installation could be to blame.
A trusted air conditioner repair tech can inspect the unit and make adjustments to overcome a poor original installation.
An improper installation could include failing to upgrade the circuit breakers to handle the new unit’s power needs, causing electrical issues. Let an AC repair tech inspect the unit and help you determine whether you need an electrician to upgrade the circuit panel.
Clogged Air Filter
A dirty air filter is among the most common causes of overheating when the AC is on. The air filter is necessary to catch dust and debris before they reach the air conditioner’s interior components.
However, a clogged air filter prevents the unit from receiving the airflow it needs to operate properly. Without air movement, the unit has to work harder to generate the desired temperature. Stress on the system from a dirty air filter can cause it to overheat and, in the worst-case scenario, fail.
To keep the system running at top efficiency, you should change or clean the air filter regularly. A repair tech in Medfield, MA, can help with this process when you sign up for a scheduled maintenance service package.
Lack of Maintenance
Regular maintenance is important to keep the air conditioner running properly. Maintenance can take care of things like dirty condenser coils and debris-covered fan blades. Cleaning techniques allow the AC unit to exchange heat properly as it operates.
Because the outdoor AC unit’s condenser coils are exposed to Medfield’s weather, dirt, pollen, and leaves can cover them. The unit needs occasional rinsing to remove the particles blocking the coils and preventing them from releasing heat. Without being able to release the heat, it builds up inside the system, exposing various parts to dangerous and excessive temperatures.
A repair tech can visit your home and perform the necessary cleaning techniques to keep the unit running at peak efficiency.
Malfunctioning Parts
A faulty thermostat is a common malfunction that can cause the AC to overheat when it is on. A compressor failure or a broken-down fan could also cause the air conditioner to overheat as it works to cool your home or business in Medfield, MA.
A repair tech can run diagnostic tests on the air conditioning system to determine which part isn’t working properly and provide a targeted solution as quickly as possible.
Some parts will simply wear out as the AC unit ages. Other parts may fail prematurely because of a lack of maintenance. Harsh weather or someone bumping into the outdoor unit with a garden tool could cause a part to break.
