The Importance of HVAC Maintenance

Maintenance is crucial when it comes to HVAC and cooling systems. It will allow you to avoid costly repairs or premature replacement. The majority of HVAC companies offer a service plan where you pay each month to have your system checked, repaired or cleaned as required.

You should also perform some DIY maintenance throughout the year. Cleaning or replacing air filters, and keeping the area surrounding outdoor units free of clutter will help ensure the proper airflow.

Clean the Condenser

The coils in the condenser of your air conditioner are the primary component of the cooling process. If they’re dirty, your system will be unable to cool properly and may even fail to function properly. Cleaning them is a vital aspect of HVAC maintenance. Fortunately, it is also quite simple to do. This easy DIY task will help you save money, avoid costly repairs and prolong the life of your air cooling.

In the beginning, it is essential to cut off the power supply to your unit. This can be done by shutting off the breaker in the electrical box, or by turning off the outdoor unit disconnect switch. This will stop your motors and other electrical components from becoming oversaturated during cleaning.

When the power is turned off it is now time to clear any large debris that is blocking the air condenser unit. This means cleaning up any leaves, sticks or other debris that has been accumulating on or around the unit. A shop vacuum with a crevice tool is an excellent way to get into the nooks, crannies and remove dirt or dust that has built up.

The next step is to clean the coils. Be sure to have some essential tools available prior to beginning. These will include a coil cleaner concentrate and a pump-up garden sprayer and a garden hose. Spray the coil cleaner according to the instructions on the product’s label and rinse with the hose. It is crucial not to apply too much pressure when washing the coils because the fins may be bent.

After the coils have been cleaned, examine them for indications of damage. Over time, hail and rocks that are thrown by lawnmowers and other objects can cause damage to coil fins. Fin combs can be used to straighten bent fins to ensure improved airflow and coil performance.

After you have a proper coil and fin set up and you are ready to start your air conditioner. After around 24 hours, you should check the thermostat and ensure that temperatures are normal.

Cleaning the Ductwork

Your HVAC system is designed to bring air from outside into your home, cool it, and then distribute it throughout the home. Air is moved from the evaporator of your condenser to your home’s registers and vents through the system of ducts. These ducts can become clogged with dust and other contaminants when they aren’t maintained and sealed correctly. This could block air filters which can reduce the effectiveness of your system as well as strains your AC unit.

In most cases, cleaning the ductwork is not an easy task and requires the help of professional equipment and methods. But, there are things you can do on a regular basis to ensure that your ducts stay in good condition and function properly. First, you should change your filter regularly to prevent dust and allergens from accumulating in the ducts. This also helps to prevent the clogging that can result in a lower efficiency of the system and a high energy bill.

Cleaning the area around the vent openings is a different method to keep your ducts in good shape. The hose attachment on your vacuum cleaner will remove all the crumbs, cobwebs and other messes that have built up over time. This will increase airflow through the vent. It’s also important to ensure that your ducts are tightly sealed and insulated to keep out moisture, which can lead to mold and other biological contaminants.

Ducts that have not been cleaned on a regular basis are likely to be contaminated with a variety of contaminants, such as dust, pet dander, and pollen. These particles can cause allergies and respiratory issues, particularly for children and the elderly. Moisture in ductwork can also result in the growth of mold, which releases spores into air and poses health risks for those suffering from respiratory ailments.

It is generally recommended that you have your ductwork cleaned every three to five years to eliminate these contaminants and ensure your HVAC system is working effectively. If your ducts are well-sealed, and you change your filter regularly, it may not be necessary to clean them. You can only be certain that your ducts are in good condition by having them checked. A certified contractor can employ specific testing methods to determine the amount of particulates within your ductwork, and will recommend the suitable cleaning schedules based upon the specific circumstances.

Check the Compressor

The compressor is an essential component of the system. It has to be able to provide cool air to the ducts. If the compressor isn’t operating properly it could affect your productivity and result in downtime for your equipment. Preventive maintenance can help identify minor issues earlier, avoiding unnecessary downtime. These routine checks will also save you money by making sure that your equipment in the best condition possible.

A decrease in cooling capacity is a typical sign of a problem in a compressor. It could be caused by several different factors. One possibility is that a compressor could be working too hard due to poor airflow. This can cause wear on the bearings and decrease the life of the compressor. Another common problem is a clogged filter. Filters that are blocked can restrict airflow and cause the compressor to overheat. To prevent this, it is essential to clean or change the filters regularly based on the recommendations of the manufacturer.

A blocked filter could cause a sound of rattling in the compressor. This could be an indication that the bearings must be changed. It is also a good idea to replace pulleys and belts regularly. A belt or pulley that is loose can cause slippage and cause overheating of the compressor and other issues. It’s also a good idea to drain your compressor regularly. This can remove accumulated moisture that can corrode the motor and other components. A professional service team will also check for leaks in the hoses, and a tight seal on the compressor and pressure sensor.

A puddle of liquid near the compressor could be a sign of an issue. This could be a risky issue and should be repaired immediately. If you suspect that there is a leak, shut off the compressor that is running and then contact a professional.

Check the Thermostat

The thermostat is kind of like the boss of your HVAC system, and it’s not a surprise that it’s the first thing that a technician will inspect when a problem arises. It’s also among the most frequently neglected maintenance items, yet maintaining your thermostat properly is vital to ensure your HVAC system’s operation. Check your thermostat if find inaccurate temperature readings, unresponsive controls, or continuous cycling.

Inaccurate Temperature Readings

Thermostat sensors may become dirty over time, which can cause the thermostat to display incorrectly. Regularly checking the accuracy of your thermostat with a separate thermometer will help you avoid these problems and conserve energy.

A defective sensor or a faulty calibration can cause your system to turn off and on constantly. This is called short cycling. This can negatively impact your comfort and result in unnecessary wear and tear on the compressor. Fortunately this can be fixed with the simple act of replacing the thermostat’s batteries or resetting its breakers.

If your thermostat isn’t responding to your thermostat at all, it’s recommended to examine the breakers that control the thermostat and your HVAC equipment. If the breaker has tripped, it’ll need to be reset in order for the thermostat to communicate with the system again.

It’s also important to check your thermostat for any signs of wear or damage. Check for dirt or dust and ensure that the thermostat isn’t too much exposed to sunlight. The fan blades must be inspected for signs of damage or rust. These simple checks can help avoid expensive repairs in the future, and will ensure that your equipment is running as smoothly as it is possible.

Performing basic hvac maintenance on your commercial property is an excellent method to cut energy costs, maintain comfort and extend the longevity of your heating and cooling equipment. By identifying issues with your thermostat, setting the breaker, and then replacing the batteries, you’ll be able to keep your building cool all year. Make sure that if you have any other issues, or are unsure about the issue you should always consult a professional.
