The Importance of HVAC Maintenance
When it is about your heating and cooling system, regular maintenance is the key to avoiding costly repairs or premature replacement. The majority of HVAC companies offer a service plan that you pay an affordable monthly fee to have your system checked, repaired or cleaned as needed.
It’s also recommended to do a few DIY maintenance tasks throughout the year. Cleaning or replacing air filters, and keeping the area around outdoor units clear of debris will promote the proper airflow.
Clean the Condenser
The coils inside the condenser of your air conditioner are the heart of the cooling process. If they are dirty, your system will struggle to cool and could even breakdown. Cleaning them is an essential part of HVAC maintenance. It’s also quite simple to do. This simple DIY task will save you money, avoid costly repairs and prolong the life span of your air cooling.
It is essential to disconnect power from your unit first. This can be accomplished by shutting off the breaker inside your electrical box or by turning off the outdoor unit disconnect switch. This will protect your motors and electrical components from being flooded when cleaning.
After the power has been shut off, you can begin to clear any large debris that is obstructing the air condenser unit. This includes cleaning up any leaves, sticks or other debris that has been accumulating on or around the unit. Utilizing a shop vacuum that has a crevice attachment is a great option to reach into the nooks and crannies and get rid of any dust, dirt or other debris that has accumulated.
The coils need to be cleaned. Before you do this, though, make sure you have several essential tools. These include a coil cleaner concentrate and a pump-up garden hose and a garden hose. Spray the coil cleaner according to the instructions on the product’s label and rinse with the hose. It is essential not to apply excessive pressure when washing the coils as the fins can easily be bent.
After the coils have been cleaned, examine them for indications of damage. Over time, the impact of hail and stones dropped by lawnmowers or other items can damage coil fins. Fin combs are a great way to straighten bent fins for better airflow and performance of the coil.
When the fins and coils are in good shape If you are satisfied with the condition of your fins and coils, return to your house and start your air conditioning. Make sure to check the thermostat after 24 hours to ensure temperatures are normal.
Cleaning the Ductwork
Your HVAC system works by bringing air in from outside, cooling it, and distributing it throughout your home. The air moves from the evaporator coil inside your condenser unit and then to the vents and registers of your home through a duct system. If the ducts aren’t cleaned and sealed, they could be laden with dust and other pollutants. This can clog the air filters which reduces the efficiency of your system and burdens your AC unit.
Cleaning ductwork can be a difficult task that requires specialized equipment and methods. However, there are a few actions you can take regularly to ensure your ducts stay clean and functioning well. To avoid dust and allergens accumulating in the ducts, change your filter on a regular basis. This can also help stop clogging, which could lead to a reduced system efficiency and higher energy bills.
Vacuuming the area surrounding the vent openings is a different method to keep your ducts in good shape. Utilizing the hose attachment of your vacuum cleaner can remove all of the cobwebs and crumbs which accumulate over time, and aid in improving airflow through the vent. It is 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.
If ducts are not cleaned regularly, they could accumulate a variety of contaminants like dust, pet dander, and pollen. These particles can cause allergies and respiratory issues particularly in the elderly and children. The moisture in ductwork can lead to the growth of mold which releases spores in the air and can cause health issues for those who suffer from respiratory ailments.
It is generally recommended to have your ductwork cleaned every three to five years to eliminate these contaminants and ensure your HVAC system is working efficiently. If your ducts are sealed properly, and you regularly change your filter, it may not be necessary to clean them. The best way to know the truth is to have your ducts tested. A contractor who is accredited by the EPA can employ special testing methods in order to determine the amount of particulates that are present in your ductwork. They will then recommend cleaning schedules that are suitable for your situation.
Check the Compressor
The compressor is an essential element of the system. It must be able to provide cool air to the ducts. If the compressor isn’t functioning properly, it can affect your productivity and result in downtime for equipment. Fortunately, preventive maintenance can assist in identifying issues that are minor and avoid excessive downtime. These regular checks will also save you money by making sure that your equipment in the best condition possible.
A reduction in cooling capacity is a typical sign of a problem in a compressor. This could be caused by several different causes. One possibility is that a compressor may be overworking because of poor airflow. This can cause wear on the bearings and diminish the life of the compressor. Another issue that is common is a blocked filter. If the filter has become clogged, it can reduce the airflow to the compressor, which can cause overheating. It is essential to change or clean the filters according to the manufacturer’s recommendations.
A clogged filter may also cause a sound of rattling in the compressor. This could be an indication that the bearings require to be changed. It is recommended to replace belts and pulleys regularly. A worn-out belt or pulley can slip, causing the compressor to overheat and cause other problems. It is recommended to drain the compressor regularly. This will help remove moisture that could cause corrosion to the motor and other components. A professional service team will examine for leaks in pipes, and ensure a tight seal on the compressor and pressure sensor.
A puddle of liquid close to the compressor could be a sign of leak. This can be a dangerous issue that needs to be addressed immediately. If you suspect a leak, shut off the air compressor. Get a professional to assist you.
Check the Thermostat
The thermostat acts like the boss of your HVAC system, so it’s not a surprise that it’s the first thing that a technician will look at when trouble arises. It’s also among the most often neglected maintenance items, yet a properly maintained thermostat is essential to ensure your HVAC system’s optimal operation. Common signs that your thermostat needs periodic inspections include incorrect temperature readings, unresponsive controls, or constant cycling.
Inaccurate Temperature Readings
Over time, the thermostat’s sensors can become dirty. This can cause it to display incorrectly. Monitoring your thermostat’s accuracy regularly with a separate thermometer will help you avoid these problems and save energy.
A defective sensor or a flawed calibration could cause your system to turn off and on in a continuous manner. This is referred to as short cycling. This can adversely affect your comfort and result in excessive wear and tear on the compressor. Fortunately this can be fixed with simply replacing the batteries in your thermostat or resetting the breaker.
If your thermostat isn’t responding to your thermostat in any way it’s an excellent idea to look at the breakers that regulate the thermostat as well as your HVAC equipment. If the breaker has tripped, you will need to reset it in order for your thermostat to reconnect with the system.
It is also essential to examine your thermostat for signs of wear or damage. Look for dust or dirt and make sure that the thermostat is not too much exposed to sunlight. Examine the fan blades to find signs of damage and rust. These simple checks will prevent costly repairs in the future and will ensure that your equipment is running as smoothly as it can.
Performing basic hvac maintenance on your commercial building is a great way to reduce energy consumption, ensure comfort and prolong the life of your cooling and heating equipment. You can ensure that your building stays comfortable throughout the year by identifying problems with your thermostat, setting your breaker, and then replacing your batteries. Remember to call an expert if you’re having other issues or are unsure of what’s wrong with your system.
