The Importance of HVAC Maintenance
When it is about your cooling and heating system, regular maintenance is essential to avoid costly repairs or replacements that are not needed as soon as they should be. Most HVAC companies have a maintenance plan where you pay each month to have your system checked and cleaned or repaired when needed.
It is also recommended to perform DIY maintenance throughout the year. Cleaning or replacing air filters and keeping the area around outdoor units free of any debris will ensure the proper airflow.
Clean the Condenser
The coils of the condenser of your air conditioner are at the heart the cooling process. If they are dirty your system will struggle to cool properly and may even break down. This is why cleaning them is a crucial aspect of HVAC maintenance. It’s relatively simple to accomplish. This easy DIY task can avoid the need for expensive repairs, save you money on your energy bills and extend the life of your air conditioning unit.
It is vital to cut off the power source from your unit first. You can do this by shutting off the breaker in the electrical box, or by turning off the outdoor unit disconnect switch. This will protect your electrical components and motors from being over-saturated when cleaning.
When the power is turned off it is now time to clear any large debris that is obstructing the air condenser unit. This means taking away any sticks, leaves or other debris that has accumulated on or around the unit. Using a shop vacuum with a crevice attachment is a great way to get into the crevices and nooks and loosen dust, dirt or other debris that may have accumulated.
Next, it is time to clean the coils. Before you begin however, ensure that you have in your possession a few key tools. Included in this are a coil cleaning concentrate as well as a pump-up garden sprayer as well as an outdoor hose. Spray the coil cleaner according to the instructions on the label, and then rinse with the hose. When washing the coils, it is essential not to use too much force since the fins are easily bent.
It is recommended to inspect the coils for signs of damage following cleaning. Over time, hail and stones thrown by lawnmowers, and other things can harm the coil fins. Fin combs can be utilized to straighten bent fins to ensure better airflow and coil performance.
Once the coils and fins are in good shape If you are satisfied with the condition of your fins and coils, go back to your home and turn on your air conditioner. Check the thermostat every 24 hours to ensure the temperatures are in good shape.
Clean the Ductwork
Your HVAC system is designed to bring air from outside into your home, cool it and then distribute it throughout the home. The air is moved from the evaporator coil in your condenser unit to the vents and registers of your home through a duct system. If these ducts aren’t cleaned and sealed, they could become loaded with dust and other contaminants. This clogs the air filters which reduces the efficiency of the system and puts strain on your AC unit.
Cleaning the ductwork can be a difficult task that requires professional equipment and methods. There are some actions you can take regularly to ensure that your ducts are clean and working well. First, make sure you change your filter on a regular basis to prevent dust and allergens from building in the ducts. This also helps to keep the clogs from occurring which can cause a decrease in system efficiency and a high energy bill.
Vacuuming the area around the vent openings is a different method to keep your ducts in good shape. Utilizing the hose attachment of your vacuum cleaner, you can eliminate all the cobwebs and crumbs that accumulate over time and help to improve airflow through the vent. It is also important to make sure your ducts are tightly sealed and insulated to keep out moisture, which can lead to mold and other biological contaminants.
If ducts aren’t cleaned regularly, they can accumulate a variety of contaminants like dust, pet dander, and pollen. These particles can cause allergies and respiratory problems, particularly for children and the elderly. Moisture can cause mold to develop in ductwork, which releases microbes that can harm those with respiratory problems.
It is recommended to clean your ductwork every three to five years to get rid of these toxins and ensure that your HVAC system is functioning efficiently. If your ducts have been well-sealed, and you replace your filter on a regular basis, it may not be necessary to clean them. The best way to determine the truth is to have your ducts tested. A contractor who is accredited by the EPA can use specific testing methods to determine the amount of particles that are present in your ductwork. They will then suggest cleaning schedules that are appropriate for your specific situation.
Check the Compressor
The compressor is a critical element of the system. It should be able provide cool air to the ducts. If the compressor isn’t working in the way it should, this can affect your productivity and result in interruption to your equipment. Fortunately, preventive maintenance is able to aid in identifying minor issues early and avoid excessive downtime. Performing these routine checks can also save you money by keeping your unit in good working order for as long as it is possible.
A reduction in cooling capacity is a common sign of a problem in the compressor. This can be caused by several different reasons. A compressor could be working too hard due insufficient airflow. This can cause the bearings to wear down and decrease the life of the compressor. Another common problem is a clogged filter. Filters that have become blocked can hinder airflow and cause the compressor to overheat. It is essential to clean or change the filters in accordance with the manufacturer’s recommendations.
A blocked filter can cause a rattling sound in the compressor. This could indicate that the bearings must be changed. It is recommended to replace belts and pulleys regularly. A worn-out belt or pulley can cause the compressor to overheat and create other problems. It is recommended to drain the compressor regularly. This will help remove moisture that can corrode the motor and other components. A professional service team can examine for air leaks within the hoses and a tight seal between the compressor and the pressure switch.
A puddle of liquid close to the compressor could be an indication of a leak. This could be a dangerous problem that should be addressed immediately. If you suspect there is a leak, shut off the air compressor and call a professional.
Check the Thermostat
The thermostat is like the head of your HVAC system, so it’s no surprise that it’s the first thing a technician will inspect when a problem occurs. A well-maintained thermostat is crucial to the proper operation of your HVAC system. It’s among the most frequently neglected maintenance items. Common indicators that your thermostat is in need of a check-up include incorrect temperature readings, non-responsive controls, or continuous cycling.
Inaccurate Temperature Readings
Over time, the thermostat’s sensors may become dirty. This could cause it to display incorrectly. You can avoid these problems by ensuring the accuracy of your thermostat with an additional thermometer.
A malfunctioning sensor, or a wrong calibration, could cause your system to cycle on and off continuously. This is called short cycling. This can adversely affect your comfort and result in unnecessary wear and tear on the compressor. Fortunately, these issues can often 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 in any way it’s recommended to examine the breakers that control the thermostat and your HVAC equipment. If the breaker has been tripped, it will have to be reset to allow the thermostat to be able to communicate with the system.
It’s also crucial to examine your thermostat for any signs of wear or damage. Look for dust or dirt and make sure that the thermostat is not overly exposed to the sun. Finally, the fan blades need to be examined for any signs of damage or rust. These simple checks will prevent costly repairs in the future and will ensure that your equipment is running as smoothly as possible.
The simple maintenance of hvac systems on your commercial building is a great way to reduce the cost of energy, maintain comfort and extend the lifespan of your heating and cooling equipment. By identifying any issues with your thermostat, resetting the breaker, and then replacing the batteries, you’ll be able to keep your building warm all year round. Make sure that in case you experience any other issues or are unsure about what’s wrong with your system you should always consult an expert.
