Why HVAC Unit Maintenance Is Important?

Your air conditioning system works as a car. It needs regular maintenance and care like a car for proper working, which extends its service life. A properly working HVAC system can keep your house warm or comfortable for many years.

There are many advantages of a properly working HVAC system, and some of them are given below:

1) Lower Utility Bills

The proper maintenance of the HVAC unit reduces the utility bills. Efficient HVAC units in combination with well-insulated houses reduce the costs of cooling, heating, and electricity. Air conditioning maintenance is also important to avoid costly repair or complete replacements.

2) Ensure Healthy Indoor Air

A well-maintained HVAC system keeps your building comfortable and cool, as well as it also improves indoor air quality problems. The good working air cleaner filters and coils ensure good quality breathing air for the whole family.

Unmaintained air conditioner attracts bacteria, mold, and dust, mixing them with indoor breathing air and transferring it inside the building. All of these contaminations can cause or worsen breathing difficulties for the household family.

3) Extend HVAC service life

The proper maintenance of your HVAC system increases the service life of your system. The cost of an HVAC system is very high.

As you buy this system for your house or building, you will desire that it works for a long time. Therefore, for long-time proper working, the proper maintenance and repair of HVAC unit are essential.

4) Improve Efficiency

A most efficient HVAC unit is cheaper to run and consumes less energy. An unmaintained or dirty system requires 20% more electricity to produce the same level of heating or cooling as a properly maintained air conditioning system.

5) Very Low Emergency Repairs

Sometimes, the HVAC system may require urgent repair. A properly maintained equipment is less likely to fail during a season of continuous use, such as for the cold winter months from November to April and the summer months from July to September.

Therefore, keep your air conditioner up-to-date through consistent inspection and maintenance, which will eliminate the risk of HVAC outages in the most urgently needed months and save future HVAC maintenance costs.

Pro Tips to lower HVAC Repair or Maintenance Cost

1) Clean the Condenser, Compressor or Heat Pump

Sometimes, the outdoor heat pump, condenser, and compressors can become very dirty; due to that, the system runs harder to produce the warm or cold air needed in the building.

Therefore, the proper cleaning of the compressor, heat pump, and condenser is very important for the proper working of the system.

The proper cleaning of these parts reduces the possibility of damage to the internal components of the HVAC system. Therefore, the homeowner should ensure no debris on the casing or side of the air conditioner pump and other parts.

2) Check the Filter

Dirty air filters are another major reason of the air conditioning system failure or repair. Filter replacement is a cheapest and easiest method to perform HVAC maintenance to increase the air conditioner efficiency, improve indoor air quality, lower heating energy costs, and reduce the possibility of repairs.

You must inspect your air filters once a month to make sure that they are clean and free from clogs. If they are dirty, it is the best option to clean them properly, blow air over them, and use them.

You must change the filter of your air conditioning at least once every three months.  If it looks dirty than usual, especially if you have pets in your house, change them at least one time within 3 months.

If you are using a reusable filter, gently clean it with a soft cloth. Then mix mild soap and water and wash the filter.

3) Regular or Annual Professional Inspections

In the on-site inspection, an HVAC professional inspects the HVAC system and ensures that it is operating at its best. In the inspection, the professional performs the following actions:

  • Ensuring the fan is working properly
  • Checking the furnace heat exchanger for leaks
  • Air filter cleaning
  • Measuring the refrigerant level
  • Cleaning of the drain pipes
  • Coils cleaning

The inspection can be carried out once or once a year as part of regular maintenance.

4) Clean the Drain Lines

When cooling the indoor air, the air conditioning system also removes humidity from the indoor air. This humidity collects in the air conditioner drain lines from where it is removed into the environment. With the passage of time, the dust and dirt build-up inside the drain lines due to that these lines can clog and reduce the performance of your system.

Therefore, it is recommended to clean the drain pipe regularly. Remove the air conditioner housing and clean the drain lines with a clean cloth.

5) Keeping the Outdoor Unit Clear

Outdoor units are constantly exposed due to environmental influences such as debris, dirt, weather, and other contaminations.

In addition, with time, the growth of plants covers the outdoor units and stops the outdoor air from existing effectively.

Therefore, you must continuously monitor the area around the outdoor unit and observe the bushes and leaves that need pruning.

How to do HVAC maintenance?

You need to check and perfom the following major steps for the HVAC maintenance:

  1. Use good filters
  2. Clear debris around the outdoor units
  3. Check refrigerant lines monthly
  4. Maintain your unit level
  5. Eliminate clogs
  6. In Summer, Turn off water supplied to your furnace’s humidifier
  7. Don’t shut too many registers
  8. Odors and noises

hvac Maintenance guide

1) Use Good Filters

As mentioned above, you must change your air filter within 30 to 90 days. The proper maintenance of the HVAC air filters prevents you from expansive repair.

The clean filters improve the indoor air quality and efficiency of your HVAC system. A dirty filter means your system will have to work harder to keep your room at your desired temperature.

2) Clear Debris Around the Outdoor Units

Debris can easily build up around outdoor units of HVAC equipment. If you have trees around the outdoor units, their leaves fall in autumn. These leaves and many other contaminations may collect on the outdoor units of your air conditioner.

This contamination collection may clog or damage the outdoor units. Therefore, regularly inspect your outdoor unit to ensure that there is at least 60 cm of free space around the heat pump or air conditioner.

3) Check Refrigerant Lines Monthly

The refrigerant pipes that enter from HVAC equipment to your home ensure cooling or heating for your building.

If these pipes fall out, leak, or wear out, you can’t achieve a comfortable temperature according to your requirements. Therefore, check these lines at least once a month, even in winter, and ensure their proper working.

4) Maintain Your Unit Level

The level of the HVAC or air conditioning affects the performance of the HVAC. For the HVAC system to function properly, you need to make sure that it is leveled properly and not sloped.

Therefore, after every 2 to 3 months, you need to ensure that the system is properly level with the floor. If you place the unit on pads, ensure that they can’t move.

5) Eliminate Clogs

This is a great DIY hack for preventing algae and mold from building up in your system. After every 10 to 12 months, mix the bleach with a glass of water and pour it down the drain of the air conditioner condenser to remove the buildup of algae or mold.

6) In Summer, Turn off Water Supplied to Your Furnace’s Humidifier

A running humidifier is useless and increases the utility bill in the summer. If the air begins to cool in summer end or early fall and you are considering turning on the heater, replace a new filter and adjust the humidity up to 40%. After this setup, turn on the supply of the water.

7) Don’t Shut Too Many Registers

You don’t need to close more than 20% registers of your house. If you do so, this puts an extra load on the HVAC unit by forcing it to work harder to deliver the desired amount of cooling or heating.

8) Odors and Noises

Pay attention to strange smells or noises when starting the device. The unusual smell or sounds may occur due to damaged or failed parts of the system.

How to do Troubleshoot and Repair an Air Conditioning system?

The repair of the HVAC or AC system can be performed in the following way:

  1. Shut-off the power
  2. Remove dirt from the condenser coils
  3. Test the fuse
  4. Check the inside of the access panel
  5. Replace the start/run capacitor
  6. Replace the air conditioner conductor
  7. Test HVAC or AC Repair
1) Shut-off the Power :-
  • First of all, open the electrical box and remove the insulating block.
  • Use a voltage detector to check the inner side of the box to ensure that the power is really shut-off.

Shut-off the Power from the hvac system

2) Remove dirt from the Condenser Coils :-
  • Lift the nozzle up at the condenser coil top to eliminate any debris that has accumulated under the cap.
  • Then push the nozzle downward to remove debris from the fins of the coil.
  • Set the nozzle for a gentler flow of water, then spray water directly onto the coil to remove any residual residue.

4) Check the Inside of the Access Panel :-

Follow the electrical wiring inside the house to find the access panel. After the electricity power off process, detach the panel by removing the screws which secure the access panel. Please, place the screws in a safe place from where you can easily find them. After this process, inspect the wiring.

If the wire is broken or the insulator is bitten off, and an electrical repair is safe then firstly discharge the capacitor. Then repair the electricity cables and clean the nest. Otherwise, contact an expert.

5) Replace the Start/Run Capacitor :-

An AC service unit has at least one capacitor. The main objective of the capacitor is to store electricity and release electrical energy when the condenser and compressor start working.

This unit of the AC system supplies the two motors with additional power. It also eliminates voltage fluctuations and protects condenser fan and compressor motors from damage.

Due to this reason, the proper repair, service, or replacement of the air conditioner (AC) capacity is very important on time.

6) Replace the Air conditioner Conductor :-

AC contactor is an electrical relay that takes a low-voltage power supply from a thermostat to transfer a high-amperage, 220-volt current to a condenser fan and compressor.

This contactor may wear out, which is a most common reason for the AC service or repair. You must replace the contactor after every 5 years even if the AC contactor works normally. Unscrew the old air condition contactor before eradicating the wires. Then insert the wires into the new device.

7) How to test HVAC or AC Repair :-
  • Reinstall the access panel and remove the block.
  • Switch on the heater and circuit breaker, fix the thermostat at a lower temperature, and wait for the air conditioner power to turn on.
  • As the compressor unit starts working then the condenser fan also starts rotating.
  • If the compressor works but the fan is not working, it may be possible that your fan motor has been burned out. In such condition, follow the below-given procedure:
    • Turn off the power supply and eliminate the housing of the condenser.
    • Remove the motor and fan blades.
    • Reinstall the fan blades and tightly close the housing.
    • Turn on the power and see whether the fan is working or not.
    • If the fan is not working then you must call a technician.
