The Importance of HVAC Maintenance
Maintenance is key when it is concerned with HVAC 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 an affordable monthly fee to have the system checked, repaired or cleaned if necessary.
It is also recommended to perform DIY maintenance throughout the year. This includes cleaning or replacing air filters, and keeping the space around outdoor units free of debris to promote proper airflow.
Clean the Condenser
The coils inside the condenser in your air conditioner are the heart of the cooling process. If they are dirty, your system will struggle to cool and may even fail. Cleaning them is a crucial part of HVAC maintenance. It’s also quite simple to do. 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.
In the beginning, it is essential to cut off the power to your unit. This can be done by shutting off the breaker inside the electrical box, or by turning off the outdoor unit disconnect switch. This will stop your motors and other electrical components from getting overloaded while cleaning.
Once the power is off, you can begin removing any large debris that may be blocking the condenser’s air. This includes sweeping away any sticks, leaves, or other debris that have accumulated on or around the unit. A shop vacuum equipped with crevice tools is a great way to reach into the nooks and crannies, and loosen dirt or dust that has accumulated.
The coils must be cleaned. Before doing this however, make sure that you have on-hand some essential tools. These will include a coil cleaner concentrate and a pump-up garden hose and a garden hose. Spray the coil cleaner on according to the instructions on the product’s label and rinse with the hose. It is important not to use excessive pressure when washing the coils, as the fins can easily be bent.
After the coils have been cleaned, you should inspect them for any signs of damage. Over time, the impact of hail and stones thrown from lawnmowers or other items could damage the 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.
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 switch on your air conditioner. After approximately 24 hours, you should check the thermostat to ensure that temperatures are normal.
Clean the Ductwork
Your HVAC system is able to bring air from outside into your home, cool it, and then distribute it throughout your house. Air is moved from the evaporator inside your condenser unit to your home’s registers and vents through the system ducts. The ducts could become blocked with dust and other pollutants when they aren’t maintained and sealed correctly. This can block the air filters, which decreases the efficiency of your system and can strain your AC unit.
Cleaning ductwork can be a challenging task that requires expert equipment and techniques. There are a few things you can do regularly to ensure that your ducts are clean and working well. To avoid dust and allergens from accumulating in the ducts, it is recommended to change your filter regularly. This can also help stop clogging, which could lead to a reduced system efficiency and higher energy costs.
Another way to help keep your ducts clean is to regularly cleaning the area around vent openings. The hose attachment on your vacuum cleaner will remove all the crumbs, cobwebs and other messes that have been accumulating over time. This will increase the flow of air through the vent. You should also make sure that your ducts are sealed tight and protected from moisture getting in, which could lead to mold and other biological contaminants.
If ducts are not cleaned regularly, they can build up a myriad of contaminants like dust, pet dander and pollen. These particles can cause a flare-up of respiratory issues and allergies particularly for older people and children. Moisture can cause mold to develop in the ductwork, which releases the spores that can be harmful to people suffering from respiratory issues.
It is generally recommended that you have your ducts cleaned every three to five years in order to eliminate the toxins and ensure that your HVAC system functions efficiently. If your ducts have been sealed well and you change your filter regularly it might not be necessary to clean them. You can only be sure that your ducts are in good condition by having them checked. An accredited contractor can use special testing methods to measure the amount of dust particles within your ductwork, and will recommend the appropriate cleaning schedules that are based on the specific circumstances.
Check the Compressor
The compressor is an essential component of the system. It must be able to provide cool air to the ducts. If the compressor isn’t working as it should and isn’t functioning properly, it could impact your productivity and cause the equipment to shut down. Preventive maintenance can help spot minor issues earlier, avoiding excessive downtime. Performing these routine checks can also help you save money by keeping your unit in good working order for as long as possible.
The most common sign of a compressor problem is a loss in cooling capacity, although it could be caused by many different causes. A compressor may be operating too hard due to poor airflow. This can cause the bearings to wear down and reduce the lifespan of the compressor. Another common issue is a clogged filter. Filters that are clogged can reduce airflow and cause the compressor to overheat. To avoid this, it is crucial to clean or replace the filters frequently, according to the recommendations of the manufacturer.
Additionally, a blocked filter can create a rattling sound inside the compressor. This could be an indication that the bearings must be changed. It is recommended to replace pulleys and belts regularly. A loose pulley or belt can slip and lead to compressor overheating and other issues. It’s also a good idea to drain your compressor frequently. This will remove the accumulated moisture that can corrode the motor and other components. A professional service team can check for air leaks in the hoses as well as an adequate seal between the compressor and pressure switch.
A small puddle of water around the compressor can be a sign of a leak in the refrigerant. This is a risky problem that should be addressed immediately. If you suspect a leak, turn off the air compressor. Contact a professional.
Check the Thermostat
It’s not surprising that a technician will always examine the thermostat first if there is a problem. It’s also among the most often neglected maintenance items, yet maintaining your thermostat properly is essential to ensure your HVAC system’s operation. The most common signs that your thermostat needs a check-up include incorrect temperature readings, ineffective controls, or constant cycling.
Inaccurate Temperature Readings
Over time, the sensors on your thermostat may get dirty. This can cause it to display inaccurately. You can prevent these issues by checking the accuracy of your thermostat with the use of a separate thermometer.
A malfunctioning sensor or calibration may lead to your system continuously switching off and on that is known as short cycling. This can negatively impact your comfort, and cause excessive wear and tear on the compressor. These issues can be resolved by replacing the thermostat’s batteries or resetting the breaker.
Check the breakers for your thermostat and HVAC equipment if your system doesn’t respond to your thermostat. If the breaker has tripped, you will need to reset it to allow your thermostat to communicate again with the system.
It’s also crucial to examine your thermostat for signs of wear or damage. Check for dirt or dust and make sure that the thermostat isn’t too much exposed to sunlight. Lastly, the fan blades must be inspected for any signs of damage or rust. These simple checks can prevent costly repairs in the future and will ensure that your equipment operates as smoothly as it possibly can.
The simple maintenance of hvac systems on your commercial building is a great way to reduce the cost of energy, maintain comfort and prolong the lifespan of your heating and cooling equipment. By identifying problems with your thermostat, setting the breaker, and then replacing the batteries, you’ll be able to keep your building cool all year. Be sure to call a professional if you are experiencing any other issues or are unsure of what’s wrong with your system.
