Air conditioners, like so many other mechanical equipment in our houses, are utilized just when they’re needed and otherwise disregarded until they break down. That’s when we contact a service professional and begin praying that the bill will be reasonable. Neglecting basic maintenance on air conditioners results in decreased efficiency. In other words, increased utility costs. And in many cases, premature failure of expensive equipment.
To avoid this, get your central air conditioning system inspected by a certified professional once a year. A regular air conditioner or commercial HVAC maintenance call should include the items listed on the checklist below. During the cooling season, in addition to the annual service, it’s critical to check on a few things every month. This is something you can perform in a matter of minutes on your own.
- 1. Clean the condenser coils outside and the evaporator units inside:
- 2. Make sure the refrigerant level is correct:
- 3. Examine the condensate drains and drains pans:
- 4. Inspect the motor and blades of the outside fan:
- 5. Make sure all moving parts are lubricated (as applicable):
- 6. Examine any electrical controls, connections, and wiring:
- 7. Air filters should be inspected and cleaned or replaced as needed:
- 8. Perform a system-wide test:
- 9. Look for leaks and other issues in the ductwork:
1. Clean the condenser coils outside and the evaporator units inside:
The refrigerant lines and surrounding radiator-like fins that line the cabinet of your outdoor air conditioner make up the coil. The evaporator, which has its own coil, is the inside counterpart of the outdoor device. Dirt and dirt on the coils limit efficiency and put a strain on the mechanical components of the system.
2. Make sure the refrigerant level is correct:
When a compressor is overworked due to an inappropriate amount of refrigerant, the system’s efficiency and lifetime suffer. If any of the refrigerant tubes leaks, the system will require immediate HVAC repair. This is because the system will not be able to cool the house without refrigerant. These A/C repairs frequently necessitate a professional’s touch in order to correctly manage the coolant and avoid repeat leaks.
3. Examine the condensate drains and drains pans:
To avoid excess moisture being retained in the units or within the house, drains must be unobstructed and clean. Examine the drain pan within the air handler with a flashlight. Check for any evident backups or debris at the condensate drain line’s opening. As much as possible, clean out the drain pan. You most likely have a drain line clog if there is condensate in the overflow pan.
4. Inspect the motor and blades of the outside fan:
Air is drawn in through the coil fins by the fan on the outdoor unit. Your furnace’s indoor blower is the fan unit such as motor, fan wheel, and housing. A drive belt on older blowers should be inspected and adjusted or replaced as needed.
5. Make sure all moving parts are lubricated (as applicable):
Fan motors, compressors, and other elements on older air conditioners often include ports for applying lubricant on a regular basis. Newer models usually feature sealed sections that don’t require lubrication.
6. Examine any electrical controls, connections, and wiring:
Check all electrical components and connections for soundness, wear, and damage. You’ll need to power up the circuit board if the components appear to be in good condition. With the multimeter, check the voltage of the power rails. The voltage regulator’s input and output must both exhibit the expected values.
7. Air filters should be inspected and cleaned or replaced as needed:
The air supply to the system is restricted by a blocked filter, causing the motor to run without delivering any results. If necessary, clean or replace the filter. After that, examine the filter once a month. Using a clean filter might help you save up to 15% on your air conditioning bills.
8. Perform a system-wide test:
Turn on the air conditioner to verify functioning functions like the starting cycle and shut-off control, listen for strange noises or aromas, and measure indoor/outdoor temperatures and system pressures if necessary.
9. Look for leaks and other issues in the ductwork:
One of the biggest causes of inefficiency in forced-air A/C and heating systems is air leakage in the ductwork. A duct inspection is not required every year and may not be included with a normal system checkup, although it is one of the most common causes of inefficiency in forced-air A/C and heating systems. It’s a good idea to have your ductwork examined and, if necessary, sealed and/or insulated in trouble areas.
Maintenance has to be performed once a month during the fall and winter Seasons
Now, here are a few things you can do to assist keep your air conditioner in good working order while you’re using it the most:
- Firstly, check the furnace and if the conditions is alarming then it is better to replace it.
- Next, inspect the exterior condenser unit for leaves, grass clippings, and other debris on the cabinet’s sides and top.
- Thirdly, maintain a minimum of two feet of clearance on all sides of the unit by cutting back bushes and other plants as needed. This way you stay ensured that enough air will reach the condenser coil.
Early spring in most places, or at least well before the cooling season truly sets in, is the optimum time to call a commercial or home air conditioner repair technician for an annual air conditioner maintenance review. If you wait until the summer, the professionals will be swamped with emergency repairs and installations. And that can increase service prices too. Pro-tip, whenever you get an air conditioner installed ask if the company offers services and repairs too. This way you can great deals, offers, discounts, membership plans and so on.
