The Importance of HVAC Maintenance
When it concerns your cooling and heating system, routine maintenance is the best way to avoid costly repairs or replacements that are not needed as soon as they should be. The majority of HVAC companies offer a service plan where you pay each month to have your system checked, repaired or cleaned as needed.
It’s also an excellent idea to carry out a few 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 that make up your air conditioner’s condenser are the heart of the cooling process. If they’re dirty your system is likely to struggle to cool and may even break down. Cleaning them is a vital aspect of HVAC maintenance. It is relatively easy to accomplish. This easy DIY task will save you money, prevent costly repairs, and increase the lifespan of your air cooling.
First and foremost, it is essential to cut off the power source to your unit. This can be done by turning off the breaker inside your electrical box or at the outdoor unit disconnect switch. This will stop your motors and other electrical components from becoming oversaturated 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 taking away any sticks, leaves or other debris that have built up on or around the unit. A shop vacuum that has crevice tools is a great tool to get into the nooks and crannies and remove dust or dirt that has been accumulating.
The coils need to be cleaned. Be sure to have a few essential tools available before you start. Included in this are a coil cleaning concentrate and a pump-up garden sprayer, and a garden hose. Spray the coil cleaner according to the directions on the label, then rinse it off using a water hose. It is crucial not to apply excessive pressure when washing the coils, since the fins could easily be bent.
After the coils have been cleaned, look them over for any indications of damage. Over time hail or stones thrown by lawnmowers, and other objects can cause damage to the coil fins. Fin combs can be used to straighten bent fins for better airflow and coil performance.
Once you have a good coil and fin set up, you can switch on your air conditioner. Make sure to check the thermostat after 24 hours to ensure temperatures are normal.
Clean the Ductwork
Your HVAC system is designed to bring air from outside into your home, then cool it and then distribute it throughout the home. Air is moved from the evaporator of your condenser unit to your home’s registers and vents via a system duct. If the ducts aren’t cleaned and sealed, they may become clogged with dust and other contaminants. This can block the air filters which can reduce the effectiveness of your system as well as strains your AC unit.
In most instances, cleaning ductwork isn’t an easy task and requires the help of professional equipment and techniques. There are a few things you can do to keep your ducts tidy and functioning properly. First, change your filter regularly to prevent dust and allergens from accumulating into the ducts. This can also help stop clogging, which could result in a decrease in system efficiency and higher energy costs.
Vacuuming the area around the vent openings is an additional way to keep your ducts in good shape. The hose attachment on your vacuum cleaner will take away all the cobwebs, crumbs and other messes that have accumulated over time. This will improve airflow through the vent. It is also important to ensure that your ducts are properly sealed and sealed with insulation to keep out moisture which can lead to mold and other biological contaminants.
If ducts aren’t cleaned regularly, they could accumulate a variety of contaminants like dust, pet dander, and pollen. These particles can exacerbate allergies and respiratory issues especially for children and the elderly. Moisture in ductwork can also cause the growth of mold which releases spores into the air and can cause health issues for those with respiratory issues.
It is generally recommended to have your ducts cleaned every three to five years in order to eliminate the toxins and ensure that your HVAC system is operating effectively. If your ducts have been sealed properly, and you change your filter regularly it might not be necessary to clean them. You can be certain by having your ducts checked. A contractor who is accredited by the EPA can employ specific testing methods to measure the amount particulates that are present in your ductwork. They will then suggest cleaning schedules that are appropriate for your situation.
Check the Compressor
The compressor is a crucial element of the system. It has to be able to supply cool air into the ducts. If the compressor isn’t working properly, it could affect your productivity and result in delays for your equipment. Preventive maintenance can help identify small issues early, preventing unnecessary downtime. Regular checks can also save you money by making sure that your equipment in the best condition possible.
The most common indication of a problem with a compressor is a loss in cooling capacity, but this could be caused by various factors. A compressor may be working too hard due to poor airflow. This can cause wear on the bearings and diminish the life of the compressor. A blocked air filter is a different issue. Filters that are blocked can reduce airflow and cause the compressor to overheat. It is crucial to clean or change the filters in accordance with the manufacturer’s guidelines.
Additionally, a blocked filter may create a rattling sound inside the compressor. This could indicate that the bearings require to be replaced. Regularly replacing the belts and pulleys is a good idea. A worn belt or pulley can slip and lead to compressor overheating and other issues. It is also a great idea to drain your compressor frequently. This will get rid of moisture that can cause corrosion to the motor and other parts. A professional service team will check for leaks in the pipes, and ensure a tight seal on the compressor and pressure sensor.
Lastly, a pool of water in the vicinity of the compressor could be a sign of a refrigerant leak. This is a risky issue that needs to be addressed immediately. If you suspect that there is a leak, turn off the air compressor. Consult a professional.
Check the Thermostat
The thermostat is kind of like the boss of your entire HVAC system, so it’s not a surprise that it’s the first thing a technician will look at when trouble occurs. A properly maintained thermostat is vital to the proper operation of your HVAC system. It’s one of the most neglected maintenance items. The most common signs that your thermostat is in need of periodic inspections include incorrect temperature readings, ineffective controls, or continuous cycling.
Inaccurate Temperature Readings
Thermostat sensors can become dirty over time, which may cause the thermostat to display incorrectly. Regularly checking the accuracy of your thermostat with a separate thermometer will help you avoid these problems and save energy.
A malfunctioning sensor or calibration can also result in your system constantly turning on and off this is known as short cycling. This can negatively impact your comfort and cause unnecessary wear and tear on the compressor. These issues can be resolved by simply replacing the batteries in the 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 control the thermostat as well as your HVAC equipment. If the breaker tripped, you will need to reset it in order for your thermostat to be able to communicate with the system.
Check your thermostat for indications of wear and damage. Find signs of dirt or dust, and make sure the thermostat isn’t too exposed to sunlight. Lastly, the fan blades should be checked for any indications of rust or damage. These simple checks will prevent costly repairs in the future, and ensure that your equipment is running as smoothly as it can.
Basic hvac maintenance is a great strategy to cut down on energy costs and maintain comfort in your commercial property. It will also extend the life of your cooling and heating equipment. By identifying issues with your thermostat, resetting the breaker, and then replacing the batteries, you’ll be able to keep your building comfortable all year round. Just remember that if you have any other issues, or are unsure of the issue, always call in a professional.
