The Importance of HVAC Maintenance
Maintenance is key when it comes to heating and cooling systems. It will help you avoid costly repairs or premature replacement. Most HVAC companies offer a maintenance plan that charges an affordable monthly fee to get the system checked, fixed or cleaned if necessary.
It’s also an excellent idea to carry out some of the DIY maintenance tasks throughout the year. These include cleaning or replacing air filters, and keeping the space around outdoor units free of any debris to ensure the proper airflow.
Clean the Condenser
The coils in the condenser of your air conditioner are the core of the cooling process. If they are dirty your system will be unable to cool properly and may even fail to function properly. Cleaning them is an essential part of HVAC maintenance. It’s fairly easy to accomplish. This easy DIY task can prevent the need for expensive repairs, and save you money on your energy bills and prolong the life of your air conditioning unit.
It is vital to cut off power from your unit first. This can be done by turning off the breaker inside the electrical box, or by turning off the outdoor unit disconnect switch. This will safeguard your electrical components and motors from being flooded when cleaning.
Once the power is off it is now time to remove any large debris that is blocking the air condenser unit. This includes sweeping up any sticks, leaves or other debris that has built up on or around the unit. A shop vacuum that has crevice tools is a great tool to reach into the crevices, nooks, and loosen dirt or dust that has built up.
The coils require to be cleaned. Before you do this however, make sure you have several essential tools. Included in this are coil cleaning concentrates, a pump up garden sprayer, and the garden hose. Spray the coil cleaner in accordance to the instructions on the label, and then rinse it off using the hose. When washing the coils, it is essential not to use too much force as the fins can be bent easily.
It is recommended to inspect the coils for signs of damage after cleaning. Over time, hail and rocks thrown from lawnmowers or other items could damage the coil fins. Fin combs can be used to straighten bent fins for better airflow and coil performance.
When the fins and coils are in good condition, you can return to your house and start your air conditioning. After about 24 hours, you can check the thermostat to ensure that the temperature is normal.
Cleaning the Ductwork
Your HVAC system is able to bring air in from outside, cooling it and distributing it throughout the home. Air is transported from the evaporator of your condenser to your home’s registers and vents through a system of ducts. These ducts can become clogged with dust and other pollutants when they aren’t maintained and sealed correctly. This could block air filters which can reduce the effectiveness of your system and strains your AC unit.
In most instances, cleaning ductwork isn’t an easy job and requires the help of professional equipment and methods. However, there are some actions you can take on a regular basis to ensure that your ducts remain clean and functioning well. To prevent dust and allergens from building up in the ducts, you should change your filter regularly. This also helps to prevent the clogging that can result in a lower efficiency of the system and high energy bills.
Cleaning the area around the vent openings is another way to keep your ducts cleaner. The hose attachment of your vacuum cleaner will remove all the crumbs, cobwebs and other debris that has built up over time. This will increase airflow through the vent. It is also essential to make sure your ducts are tightly sealed and sealed with insulation to keep out moisture, which can lead to mold and other biological contaminants.
If ducts are not cleaned regularly, they could collect a variety of pollutants such as dust, pet dander and pollen. These particles can cause allergies and respiratory issues particularly for children and the elderly. The moisture can cause mold to develop in the ductwork, which releases microbes that can harm those suffering from respiratory ailments.
It is recommended to clean your ductwork every three to five years to eliminate these contaminates and ensure that your HVAC is operating efficiently. However it is possible that if your ducts are sealed and you regularly change your filters the cleaning of your ducts may not be required at all. You can only be sure by having your ducts examined. A contractor who is accredited by the EPA can employ special testing techniques to measure the amount particulates found in your ductwork. They will then recommend cleaning schedules that are appropriate for your specific situation.
Check the Compressor
The compressor is a critical component of the system. It has to be able to provide cool air to the ducts. If the compressor isn’t working properly, it can affect your productivity and cause downtime for equipment. Fortunately, preventive maintenance can aid in identifying minor issues early and prevent unnecessary downtime. Performing these routine checks can also help you save money by keeping your unit in good working order for as long as it is possible.
A decrease in cooling capacity is a common sign of a problem in a compressor. It could be caused by a variety of reasons. A compressor could be working too hard due to inadequate airflow. This could wear out the bearings and diminish the life of the compressor. Another common issue is a blocked filter. Filters that are clogged can hinder airflow and cause the compressor to overheat. To avoid this, it is crucial to clean or change the filters frequently, according to the manufacturer’s recommendations.
A blocked filter could cause a sound of rattling in the compressor. This could be an indication that the bearings require to be changed. Regularly replacing the belts and pulleys is an excellent idea. A worn belt or pulley could cause slipping and result in compressor overheating and other problems. It is also a great idea to drain your compressor regularly. This will remove the accumulated moisture that could cause corrosion to the motor and other components. A professional service team will also examine for leaks in pipes, and ensure an adequate seal around the compressor and pressure sensor.
A puddle of liquid near the compressor could be an indication of an issue. This could be a dangerous problem that should be addressed immediately. If you suspect that there is a leak, shut off the air compressor. Consult a professional.
Check the Thermostat
The thermostat is like the boss of your entire HVAC system, and it’s not a surprise that it’s the first thing a technician will inspect when a problem arises. A well-maintained thermostat is essential for the efficient operation of your HVAC system. It’s among the most frequently neglected maintenance items. Common indicators that your thermostat requires a check-up include incorrect temperature readings, non-responsive controls, or constant cycling.
Inaccurate Temperature Readings
Thermostat sensors can get dirty over time, which may cause the device to display inaccurately. Regularly checking your thermostat’s accuracy with a separate thermometer will help you avoid these problems and help you save energy.
A malfunctioning sensor or calibration can also result in your system constantly turning on and off, which is referred to as short cycling. This can negatively impact your comfort and cause unnecessary wear and tear on the compressor. Fortunately this can be corrected by simply replacing the thermostat’s batteries or resetting the breakers.
If your thermostat isn’t responding to your thermostat in any way, it’s recommended to examine the breakers that control both the thermostat as well as your HVAC equipment. If the breaker tripped it, you’ll need to reset it to allow your thermostat to be able to communicate with the system.
It is also essential to examine your thermostat for any signs of wear or damage. Examine for dust or dirt and make sure that the thermostat isn’t excessively exposed to the sun. Check the fan blades for signs of damage and rust. These simple checks can prevent expensive repairs in the future, and help ensure that your equipment is running as smoothly as it can.
Conducting basic HVAC maintenance on your commercial property is a great way to reduce energy costs, maintain comfort and extend the longevity of your heating and cooling equipment. It is possible to keep your building comfortable throughout the year by identifying any issues with your thermostat, then resetting your breaker and replacing your batteries. Make sure that in case you experience any other issues, or are unsure about the issue you should always consult an expert.
