The Importance of HVAC Maintenance
Maintenance is essential when it is concerned with heating and cooling systems. It will allow you to avoid costly repairs or premature replacement. Most HVAC companies offer a maintenance plan that charges a low monthly rate to get the system checked, repaired or cleaned when needed.
You should also carry out some DIY maintenance throughout the year. Cleaning or replacing air filters, and keeping the area surrounding the outdoor units free of clutter will help ensure the proper flow of air.
Clean the Condenser
The coils in your air conditioner condenser are the core of the cooling process. If they’re dirty, your system will struggle to cool and could even fail. Cleaning them is a crucial part of HVAC maintenance. It’s fairly easy to complete. This simple DIY task can prevent the need for costly repairs, save you money on your energy bills, and extend the longevity of your AC unit.
It is vital to cut off power from your unit before you disconnect it. This can be done by turning off the breaker in your electrical box or at the outdoor unit disconnect switch. This will keep your motors and other electrical components from becoming oversaturated during cleaning.
After the power has been shut off it is now time to remove any large debris blocking the air condenser unit. This means sweeping up any sticks, leaves, or other debris that have accumulated on or around the unit. A shop vacuum equipped with crevice attachments is a great method to reach into the crevices and nooks and get rid of any dirt, dust or other debris that may have accumulated.
The coils need to be cleaned. Be sure to have the necessary tools in your arsenal before you start. Included in this are coil cleaning concentrates and a pump-up garden sprayer as well as an outdoor hose. Spray the coil cleaner according to the directions on the product’s 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 bend easily.
After the coils have been cleaned, examine them for indications of damage. Over time hail and rocks thrown by lawnmowers and other items can damage the coil’s fins. If the fins are bent, an affordable tool called a fin comb can straighten them to improve air flow and aid in the operation of the coils more effectively.
If the fins and coils are in good condition, you can go back to your home and start your air conditioner. After around 24 hours, you should check the thermostat and make sure that the temperature is normal.
Clean the Ductwork
Your HVAC system is able to bring air in from outside, cooling it and distributing it throughout your home. Air is moved from the evaporator inside the condenser to your home’s registers and vents through the system duct. If the ducts aren’t cleaned and sealed, they may become clogged with dirt and other contaminates. This causes air filters to become blocked, which in turn reduces system efficiency and strains your AC unit.
Cleaning ductwork can be an extremely difficult job that requires professional equipment and methods. However, there are some actions you can take on a regular basis to ensure that your ducts remain clean and well-functioning. To stop dust and allergens from accumulating in the ducts, it is recommended to change your filter frequently. This can also help stop the clogging that could result in a lower efficiency of the system and a high energy bill.
Another way to keep your ducts tidy is to regularly vacuuming the area around the vent openings. Utilizing the hose attachment of your vacuum cleaner, you can eliminate all the dust and crumbs that build up over time, and will help to improve airflow through the vent. You should also make sure that your ducts are sealed tight and protected from moisture entering, which can cause mold and other biological contaminants.
If ducts aren’t regularly cleaned, they may build up a myriad of contaminants such as dust, pet dander, and pollen. These particles can trigger allergies and respiratory conditions, especially for children and the elderly. Moisture can cause mold to develop in ductwork, which releases the spores that can be harmful to those suffering from respiratory ailments.
It is recommended to clean your ductwork every three to five years to remove these contaminants and ensure that your HVAC system is functioning efficiently. However it is possible that if your ducts are sealed properly and you clean your filters frequently it is possible that duct cleaning won’t be required at all. The best way to know for sure is by having your ducts tested. A contractor who is accredited by the EPA will use specific testing methods to determine the amount of particulates found in your ductwork. They can then recommend cleaning schedules that are suitable for your specific situation.
Check the Compressor
The compressor is a crucial component of the system. It needs to operate correctly to supply cool air to the ducts. If the compressor isn’t working as it should, it can affect your productivity and cause the equipment to shut down. Fortunately, preventive maintenance is able to assist in identifying issues that are minor and avoid excessive downtime. Regularly checking your unit can also help you save money by ensuring that your equipment is in good working order for as long as is possible.
A decrease in cooling capacity is a common indication of a problem with a compressor. It could be caused by several different factors. One possibility is that a compressor could be overworking because of poor airflow. This could cause bearings to wear out and reduce the lifespan of the compressor. A clogged air filter is another frequent issue. Filters that have become blocked can hinder airflow and cause the compressor to overheat. It is essential to clean or replace the filters according to the manufacturer’s guidelines.
A blocked filter could also cause a rattling sound in the compressor. This could indicate that the bearings require to be changed. Regularly replacing belts and pulleys is recommended. A loose pulley or belt can cause slippage and cause overheating of the compressor and other issues. It is recommended to drain the compressor regularly. This can remove accumulated moisture that can corrode the motor and other components. A professional service team can examine for air leaks within the hoses, and ensure an adequate seal between the compressor and the pressure switch.
A puddle of liquid in the vicinity of the compressor could be an indication of a leak. This could be a dangerous issue that needs to be addressed immediately. If you suspect that there is a leak, shut off the air compressor. Consult a professional.
Check the Thermostat
The thermostat acts like the boss of your HVAC system, and it’s not a surprise that it’s the first thing a technician will look at when trouble arises. A well-maintained thermostat is essential for the efficient operation of your HVAC system. It’s among the most neglected maintenance items. Common signs that your thermostat needs periodic inspections include incorrect temperature readings, ineffective controls, or continuous cycling.
Inaccurate Temperature Readings
Thermostat sensors can get dirty over time, which could cause the thermostat to display inaccurately. Monitoring your thermostat’s accuracy regularly with a separate thermometer will assist you in avoiding these issues and save energy.
A malfunctioning sensor or calibration could result in your system constantly switching off and on this is known as short cycling. This can have a negative impact on your comfort and result in excessive wear and tear on the compressor. Fortunately the majority of these issues can be resolved with simply replacing the thermostat’s batteries or resetting the breaker.
Check the breakers for both your thermostat and HVAC equipment If your system isn’t responding to your thermostat. If the breaker has tripped, it will have to be reset in order for the thermostat to connect with the system.
Examine your thermostat for signs of wear and damage. Find indications of dust or dirt and ensure that the thermostat isn’t too exposed to sunlight. Check the fan blades for signs of damage and rust. These simple checks can prevent costly repairs in the future and will ensure that your equipment is running as smoothly as it possibly can.
Basic maintenance of hvac is a great way to cut down on energy costs and ensure comfort in your commercial building. It can also prolong the lifespan of cooling and heating equipment. You can keep your building cool throughout the year by identifying issues with your thermostat, then resetting your breaker and replacing your batteries. Be sure to call a professional in case you experience any other issues, or are unsure of what’s wrong with your system you should always consult an expert.
