Knowing beforehand exactly what will happen when the HVAC technician comes for the AC tune-up is always beneficial. Since your AC is an expensive investment, you naturally want no stone left unturned during its maintenance. After all, that is the best and surest way of ensuring problem-free operations throughout the season.
Annual AC tune-up is essential no matter where you live. It needs to be carried out by a trained and certified professional. Now let us talk about what happens in the AC tune-up.
Parts Of AC Tune-Up West Palm Beach
At Aztil Air Conditioning, the complete AC tune-up process is divided into three main parts. These are:
1. Inspection
2. Cleaning
3. Testing And Recalibrating
Inspection
1. Fan – The fan is a crucial part of the AC. It is responsible for pushing cool air into the home. An inspection of the fan is necessary to ensure that it is properly balanced. If the fan shifts or becomes imbalanced, it will cause irritating noise and slow the flow of treated air. One thing that you should know is that the fan has weight. When it shifts from its position, it can also hit the refrigerant line and damage it. It can even fall off entirely and damage other components in the vicinity.
2. Supply And Return Air Ducts – There are two types of ducts in your home. The supply air duct pulls the warm indoor air and passes it over the evaporator coils to lower its temperature. This cold air is then returned to the home via the return air ducts. Both these ducts are checked to make sure that no restrictions are hampering the airflow.
3. Indoor Coil And Blower Motor Assembly – Some people may be unaware that in a central heating and cooling system, the same unit is used to provide both heating and cooling. The indoor coil located above the furnace is checked for any issues like signs of corrosions, cracks, etc. It is also given a thorough cleaning to increase the surface area with which the air will come in contact. The blower motor is also checked to ensure adequate speed of the fan as it is directly responsible for the speed with which the treated air will move.
4. Wear And Tear Of Fan Bearings – The fan’s bearings are solely responsible for keeping the fan blades balanced. These little balls bear continuous pressure when the fan is rotating, resulting in their wear and tear and subsequent imbalance of the fan blades. To reduce their deterioration, the bearings are cleaned and lubricated. In extreme wear and tear cases, the entire set of bearings may need to be changed.
5. Refrigerant Line – During a tune-up, the technician will give a thorough once over to the refrigerant line to ensure there are no cracks or holes. These gaps in the refrigerant line can cause a refrigerant leak which, in turn, hampers cooling.
6. Electrical Connections – Though you may not feel it, the numerous moving parts of the AC cause vibrations that can loosen or dislodge wires. Hence, all electrical connections are tightened to ensure there are no problems.
Cleaning
1. The Outdoor Compressor And Condenser Coil – The compressor unit installed outdoors, and the condenser coil bears the brunt of nature. They accumulate a lot of dust and other debris. Cleaning the unit is essential as it will help eliminate all accumulations that restrict airflow. Usually, it is hosed down, and the fins are cleaned with the help of a brush. The condenser coil is taken out and cleaned with due care.
2. Air Filter – The air filter is critical to maintaining good indoor air quality. Though homeowners should change it every month, yet most don’t. Therefore, it is an integral part of the tune-up process. After months of trapping air impurities, the air filter becomes dirty and clogged, so we change it to help make the air you breathe clean.
3. Condensate Drainline – In its operation, the AC generates a lot of condensation, which is flushed out of the unit through the condensate drain line. Nevertheless, sometimes the drain line gets clogged, which causes water to back up and drip down on the floor, creating wet spots or puddles. Hence, the HVAC technician cleans the drain line to ensure no build-ups or obstructions inside it.
Testing And Recalibrating
1. Wiring – Once all the disconnected wiring is put back together, the complete system is tested to ensure that everything is working fine.
2. Checking Thermostat – The thermostat is the AC’s remote. The technician will take a baseline reading, and will ensure that it is communicating appropriately with the air conditioner. If not, it is recalibrated to correct the variations.
3. Thermal Expansion Belt – The thermal expansion belt regulates the flow of the refrigerant. The technician will check it to ensure that its performance is up to expectations. It will help extend the life of the cooling unit and bring down operation costs.
4. AC Valve – The AC has a valve, just like your car’s tire, to ensure no refrigerant leak. Nonetheless, due to corrosion, this valve may get damaged. The technician will check its integrity, and if it is found broken or damaged, it is immediately replaced.
5. Refrigerant Pressure Evaluation – For the AC to work optimally, the pressure of the refrigerant should be just right. Both high and low-pressure conditions will put undue strain on the cooling unit. Hence, the refrigerant pressure is evaluated to ascertain that the condenser gets the coolant in adequate quantity.
Wrapping Up AC Tune-Up West Palm Beach
The above checks are not the only things tested for accuracy and integrity during an AC tune-up in West Palm beach. These happen to be the prominent checks that the HVAC technician will carry out. Apart from these, more checks will be done like fan motor amperage and voltage, compressor’s amperage draw and voltage, temperature difference at the supply and return air ducts, etc. The idea is to ensure that all things that commonly cause AC problems are addressed well in time.
