The Importance of HVAC Maintenance
Maintenance is essential when it comes to heating and cooling systems. It will help you avoid costly repairs or premature replacement. The majority of HVAC companies offer a maintenance plan where you pay a low monthly rate to get the system checked out, fixed or cleaned if needed.
It’s also an excellent idea to carry out some of the DIY maintenance tasks throughout the year. Cleaning or replacing air filters, and keeping the area surrounding outdoor units clear of any debris will ensure proper airflow.
Clean the Condenser
The coils in your air conditioner condenser are the core of the cooling process. If they are dirty, your system will struggle to cool and could even breakdown. Cleaning them is an essential aspect of HVAC maintenance. Fortunately, it is also fairly easy to do. This easy DIY task will save you money, prevent costly repairs and prolong the lifespan of your air cooling.
First and foremost, it is important to disconnect the power source to your unit. This can be done by turning off the breaker in the electrical box, or by turning off the outdoor unit disconnect switch. This will prevent your motors and other electrical components from getting overloaded when cleaning.
After the power has been shut off, you can begin to clear any large debris blocking the air condenser unit. This means sweeping away any sticks, leaves, or other debris that have accumulated on or around the unit. A shop vacuum equipped with a crevice tool is a great tool to reach into the nooks, crannies and remove dirt or dust that has built up.
Next, it is time to clean the coils. Before you begin however, make sure you have a few key tools. These will include a concentrate of the coil cleaner, a pump-up garden sprayer and a garden hose. Spray the coil cleaner on according to the instructions on the product label and rinse with the hose. It is important not to use too much pressure when washing the coils, because the fins may be bent.
After the coils have been cleaned, examine them for indications of damage. Over time, hail and rocks that are thrown by lawnmowers and other items can damage coil fins. If the fins are bent, a cost-effective tool known as a fin-comb can straighten them for better air flow and also to help the coils function more efficiently.
If the fins and coils are in good condition Once you’re satisfied with the condition of the fins and coils, you can go back to your home and start your air conditioning. After around 24 hours, you can examine the thermostat and ensure that the temperatures are in line with normal.
Cleaning the Ductwork
Your HVAC system is able to bring outside air into your home, then cool it and then distribute it throughout the home. The air moves from the evaporator coil inside the condenser unit to your house’s vents and registers through a duct system. The ducts could become blocked with dust and other contaminants when they aren’t cleaned and sealed properly. This could block air filters, which decreases the efficiency of your system and burdens your AC unit.
Cleaning ductwork can be a difficult task that requires specialized equipment and techniques. However, there are a few things you can do regularly to make sure your ducts remain in good condition and function properly. To avoid dust and allergens from building up in the ducts, you should change your filter frequently. This can also help prevent clogging, which can lead to a reduced system efficiency and higher energy costs.
Another way to help keep your ducts clean is by regularly cleaning the area around the vent openings. The hose attachment on your vacuum cleaner will take away all traces of dust, crumbs and other messes that have accumulated over time. This will increase the flow of air through the vent. You should also make sure that your ducts have been sealed well and are protected from moisture getting in, which could cause mold and other biological contaminants.
Ducts that have not been cleaned on a regular basis can be filled with a myriad of pollutants, including dust, pet dander and pollen. These particles can cause a flare-up of allergies and respiratory conditions, especially for children and the elderly. Moisture can also cause mold to grow in the ductwork, which releases the spores that can be harmful to those with respiratory problems.
It is recommended that you clean your ductwork every three to five years to get rid of these toxins and ensure that your HVAC system is functioning efficiently. However it is possible that if your ducts are well-sealed and you regularly change your filters the cleaning of your ducts may not be necessary at all. The best way to know for sure is by having your ducts tested. A contractor accredited by the EPA will use specific testing methods to measure the amount particulates present in your ductwork. They can then recommend cleaning schedules that are appropriate for your particular situation.
Check the Compressor
The compressor is a critical component of the system. It must be able to supply cool air into the ducts. If the compressor isn’t operating in the way it should, this can affect your productivity and cause interruption to your equipment. Fortunately, preventive maintenance is able to assist in identifying issues that are minor and prevent unnecessary downtime. These routine checks will also save you money by making sure that your equipment as efficient as possible.
A common sign of a compressor issue is a decrease in cooling capacity, however it could be caused by various factors. One possibility is that a compressor may be under-performing due to inadequate airflow. This could wear out the bearings and reduce the lifespan of the compressor. A blocked air filter is another frequent issue. If the filter has become clogged it could reduce the airflow to the compressor and lead to overheating. It is crucial to change or clean the filters according to manufacturer’s guidelines.
Additionally, a blocked filter may also cause a rattling sound in the compressor. This could indicate that the bearings must be changed. Regularly replacing the belts and pulleys is recommended. A worn-out belt or pulley can slip, causing the compressor to overheat, causing other problems. It is also a great idea to drain your compressor regularly. This can remove accumulated moisture that could cause corrosion to the motor and other components. A professional service team will check for leaks in the hoses, as well as an adequate seal around the compressor and pressure sensor.
Lastly, a puddle of water near the compressor can be a sign of a refrigerant leak. This could be a dangerous problem that should be addressed immediately. If you suspect there is a leak, turn off the air compressor and call an expert.
Check the Thermostat
The thermostat acts like the boss of your HVAC system, so it’s no surprise that it’s the first thing a technician will check when trouble arises. A well-maintained thermostat is essential for the proper operation of your HVAC system. It’s among the most frequently neglected maintenance items. Check your thermostat if observe inaccurate temperature readings, non-responsive controls, or constant cycling.
Inaccurate Temperature Readings
Over time, the sensors on your thermostat may become dirty. This could cause it to display incorrectly. You can prevent these issues by regularly checking the accuracy of your thermostat using a an additional thermometer.
A malfunctioning sensor or calibration can also lead to your system continuously turning on and off this is known as short cycling. This can affect your comfort, and cause unnecessary wear and tear on the compressor. Fortunately, these issues can often be resolved with simply replacing the thermostat’s batteries or resetting the breaker.
If your thermostat isn’t responding to your thermostat at all It’s a good idea to check the breakers that regulate the thermostat as well as your HVAC equipment. If the breaker has tripped, it will require resetting to allow the thermostat to communicate with the system again.
It’s also crucial to examine your thermostat for signs of wear or damage. Look for indications of dust or dirt, and make sure the thermostat isn’t overly exposed to sunlight. Check the fan blades for evidence of damage or rust. These simple checks can help avoid costly repairs in the future, and ensure your equipment is operating as efficiently as it can.
Basic maintenance of hvac is a great way to reduce energy costs and keep your comfort in a commercial space. It can also prolong the life of cooling and heating equipment. It is possible to keep your building comfortable throughout the year by identifying issues with your thermostat, resetting your breaker, and then replacing your batteries. Make sure to contact a professional if you are experiencing any other issues or unsure of what is wrong with your system.
