Forgoing AC maintenance has long been a point of contention between homeowners and HVAC contractors. As long as the maintenance is free and does not cost a penny, its need is strictly followed by the house owner. And once that period expires, it becomes a useless activity meant for fleecing the owner’s hard-earned money. At least that’s what the popular consensus says. So for people who don’t want to spend anything on maintaining their central air conditioning unit, all we want to say is that HVAC maintenance is all about making your heating and cooling equipment reliable and working in perfect order. If you want a reliable machine, you’ve got to do it.
Today, let us discuss a few things that every homeowner must do to keep their central AC working optimally.
Why Central Air Conditioning Unit Needs Maintenance
The central AC installed in your home is responsible for keeping your indoor space at a comfortable temperature irrespective of the temperature outside. In summers, it provides cooling, and in winters, it warms the house. Therefore, it is a complex system of moving parts. With continuous use, these parts suffer wear and tear. Sometimes corrosion also plays havoc with the unit causing more damage. If these things are ignored, they develop into significant problems that can result in the complete breakdown of the machinery. Maintenance takes care of all these problems, and that is why it is a necessity.
Maintaining The Central Air Conditioning Unit
The maintenance of the central air conditioning unit is not solely the technician’s responsibility. There are a few things that homeowners with even no knowledge can take care of. So, for the sake of convenience, let us divide the maintenance into two parts:
1. Homeowners responsibility
2. Technicians responsibility
1. Keep The Complete Unit Clean – Every homeowner must keep the exterior of their central AC clean. All it needs is a little dusting periodically, and that little step will prevent dust from going inside the unit and causing problems.
2. Keep The Surrounding Area Of The Condenser Unit Clean – The outdoor unit is continuously exposed to the harsh elements of nature. The least you can do for it, ensure no bushes are growing in its immediate vicinity, or there are no piles of dust, debris, dead leaves, etc. Such accumulations and growth prevent the free movement of air around the unit, due to which it is unable to dispel heat properly.
3. Frequently Change The Air Filters – Air filters need to be changed periodically. If you wait for the maintenance technician to do it for you, they will be changed only twice a year. That is nowhere near acceptable if you are conscious of indoor air quality. Ideally, the air filter should be replaced with a clean one every month and at most once a quarter. Anything beyond that will lead to questionable indoor air quality (IAQ). Switching out the air filter is no rocket science. Most of them are clip-on types. So you remove the dirty air filter, position the clean one in its place, and lightly push it in. The clips will hold it in position, and you are done until the next time.
4. Ensure That All Vents And Registers Are Open – If you care about your central AC, ensure that all vents and registers are open. There should be no furniture placed directly in front of it blocking the airflow. Alternately, inform everyone in the house not to close them intentionally either.
1. Check The Unit For Signs Of Corrosion – The technician will inspect the complete unit for signs of corrosion and take steps to minimize its effects. Corrosion can significantly harm the metallic components inside the unit and lead to holes and cracks.
2. Tighten All Lose Components – The technician will tighten all wires and parts of the AC that have come loose. It is essential to do so to prevent the unnecessary breakdown of the AC. Sometimes the loose parts can cause short circuits leading to electrical fires.
3. Apply Lubrication To All Moving Parts – With time, the lubrication between the moving components of the AC reduces. It causes friction and undue overheating, and damage to the said component. The technician will oil or grease the parts as required to ensure their smooth movement.
4. Clean The Unit From Inside – You can take care of the outside, but the inside, too, needs cleaning. Who better than the technician to tackle it. The inside of the central AC accumulates dust. Sometimes it settles over essential components like the evaporator coil, condenser coil, etc., hampering their proper working. This accumulated dust needs to be cleaned. Thankfully, such accumulations don’t build overnight, and thus an annual cleaning will see you through a whole year.
5. Check The Thermostat – The technician will also check the calibration of the thermostat. It needs to be accurate to communicate appropriately with the central air conditioning system. Furthermore, it too is given a once-over to ensure all wires are tight and that the device itself is installed correctly.
6. Check For Refrigerant Leaks – Any loss of refrigerant means loss of cooling. There are times when the refrigerant line may develop holes or cracks from which the refrigerant leaks. These cracks need to be sealed correctly, and the refrigerant topped up to the requisite level. The AC technician handles all of this.
7. Check The Ductwork – The other important thing that the technician will check for are any leaks in the ductwork. This part is crucial as it leads to loss of treated air if left unaddressed. The technician not only checks for leaks in the duct but also fixes them.

Maintaining the central air conditioning unit is essential. It is both your responsibility as well as that of your HVAC contractor. Taking care of your investment will make for a comfortable home and hassle-free operations.
