It’s no secret that a routine maintenance visit helps your AC deliver effective cooling and last longer. But what do AC technicians truly do during a visit? This AC maintenance contractor in Kenilworth, Illinois is going to answer that below.
Checking the important parts.
Certified technicians follow a set process to make sure your AC is safe to use and does not waste energy.
First, your AC maintenance contractor in Kenilworth, Illinois will check if air is flowing properly. They also check how much refrigerant is in there, which is what makes the air cold. If there is not enough of it, or if there is a leak somewhere, your AC will not cool properly, and your energy bills may increase.
They also check wires. If anything is loose or dirty, they clean it, tighten it, and sometimes apply a non-conductive coating to prevent overheating or sparking.
They also clean the evaporator and condenser coils. When the coils are dirty, heat does not move out of the unit as easily. As a result, the AC must run longer or at higher power to cool your home properly. This increases the risk of unexpected system breakdowns and higher monthly bills.
Making sure the water drains properly.
Your AC pulls moisture from the air, and that moisture must drain somewhere. AC technicians clear out the drain line, so water does not get stuck and overflow into your home. If the line gets clogged, you might see wet spots on your ceiling or floors.
They also check if there is a backup system (like a second drain pan or a shut-off switch) that can catch leaks before they spread. This is especially important if your AC is in the attic or elsewhere that isn’t easy to reach or repair.
If water just sits there in the drain pan, it can grow mold. The technician will therefore check that the pan is clean and tilted properly to drain water out.
Checking the electrical parts and controls.
Certified technicians will also go over all the electrical connections to make sure everything is tight, clean, and not at risk of causing a short or breakdown. If something is loose, rusty, or starting to wear down, they will fix it immediately.
They also make sure your thermostat reads the temperature correctly. If it does not, the AC might turn on or off at the wrong times. That can make your home feel too hot or too cold, and it can cause the system to run unnecessarily.
Keeping the outdoor unit in good condition.
The outdoor condenser unit needs space around it so air can move freely. A qualified AC maintenance contractor in Kenilworth, Illinois will clear away anything blocking it, like leaves, weeds, or dirt, to prevent clogging.
They will spray down the coil with water to get rid of dust and straighten any bent fins to keep air flowing properly. They also check that the whole unit is sitting flat on the ground to ensure the motor and compressor don’t get out of balance.
They also check the insulation on the pipes and the little caps on the service valves. These small checks can prevent hot air from entering your home and affecting the cooling process.
Cleaning the filters and improving airflow.
Filters clean the air and keep the AC working efficiently. If the filter is dirty, the airflow slows down, and the AC must push harder to maintain the desired temperature. The technician will make sure that the filter is the right size and the right type for your unit.
If they see dust on the blower wheel, they will clean that too. This will keep the noise level down and improve airflow. As a result, your home will feel more comfortable without needing to lower the temperature.
