The Importance of HVAC Maintenance
Maintenance is essential when it is concerned with cooling and heating systems. It will help you avoid costly repairs or premature replacement. The majority of HVAC companies offer a service plan that allows you to pay an annual fee to have your system checked, repaired or cleaned as required.
It’s also a good idea to perform some of the DIY maintenance tasks throughout the year. This includes cleaning or replacing air filters, and keeping the areas around outdoor units clear of clutter to allow for the proper airflow.
Clean the Condenser
The coils in the condenser of your air conditioner are the core of the cooling process. If they’re dirty, you system will struggle to cool and could even fail. This is why cleaning them is a vital part of HVAC maintenance. It’s also relatively simple to complete. This easy DIY task will eliminate the need for expensive repairs, and save you money on your energy bills and extend the longevity of your AC unit.
First and foremost, it is important to disconnect the power source to your unit. This can be done by turning off the breaker at your electrical box, or by turning off the outdoor unit disconnect switch. This will safeguard your electrical components and motors from being flooded when cleaning.
After the power has been shut off, you can start clearing any large debris that may be blocking the condenser air. This includes sweeping up any sticks, leaves, or other debris that have been accumulating around or on the unit. Using a shop vacuum with crevice attachments is a great method to reach into the nooks and crannies and remove dust, dirt or other debris that has collected.
The next step is to clean the coils. Before doing this however, ensure that you have in your possession several essential tools. These will include a concentrate of the coil cleaner and a pump-up garden hose and a garden hose. Spray the coil cleaner in accordance with the instructions on the label, then rinse with the water hose. When washing the coils, it is essential not to use too much force as the fins are easily bent.
After the coils have been cleaned, inspect them for any signs of damage. Over time hail, rocks thrown by lawnmowers and other things can harm the coil fins. If the fins are bent, a cost-effective tool known as 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 Once you’re satisfied with the condition of the fins and coils, you can go back to your home and start your air conditioning. Check the thermostat after about 24 hours to ensure the temperatures are in good shape.
Clean the Ductwork
Your HVAC system is able to bring air in from outside, cooling it and distributing it throughout the home. The air travels from the evaporator coil of the condenser unit to your home’s vents and registers through a network of ducts. These ducts can become clogged with dust and other pollutants if they are not cleaned and sealed properly. This causes air filters to become blocked and reduces the efficiency of the system and puts strain on your AC unit.
Cleaning the ductwork is a challenging task that requires specialized equipment and techniques. However, there are some actions you can take on a regular basis to ensure your ducts remain in good condition and function properly. First, change your filter on a regular basis to keep dust and allergens out of building in the ducts. This will also help prevent clogging, which can cause a decrease in efficiency and higher energy bills.
Vacuuming the area surrounding the vent openings is an additional way 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’s also important to ensure that your ducts are tightly sealed and insulated to keep out moisture which can cause mold and other biological contaminants.
If ducts aren’t cleaned regularly, they could collect a variety of pollutants like dust, pet dander, and pollen. These particles can exacerbate allergies and respiratory conditions particularly for older people and children. The moisture can cause mold to develop in the ductwork, releasing the spores that can be harmful to people suffering from respiratory issues.
It’s generally recommended that you get your ductwork cleaned every three to five years to remove these contaminates and ensure that your HVAC system is working effectively. If your ducts are well-sealed, and you regularly change your filter it might not be necessary to clean them. You can only be certain that your ducts are in good condition by having them checked. A contractor that is certified by the EPA can use special testing methods in order 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 an essential component of the system. It should be able deliver cool air into the ducts. If the compressor isn’t operating as it should and isn’t functioning properly, it could impact your productivity and cause equipment downtime. Preventive maintenance can help identify minor issues earlier, avoiding unnecessary downtime. Conducting these regular checks can also save you money by keeping your unit in good shape for as long as is possible.
A reduction in cooling capacity is a typical indication of a problem with the compressor. It could be caused by several different reasons. A compressor may be operating too hard due insufficient airflow. This can cause bearings to wear down and decrease the life of the compressor. Another common issue is a clogged filter. If the filter is blocked it can impede airflow to the compressor and cause overheating. To prevent this, it is crucial to clean or replace the filters regularly based on the manufacturer’s recommendation.
Additionally, a blocked filter could also cause a rattling sound in the compressor. This could be an indication that the bearings must be changed. Regularly replacing pulleys and belts is recommended. A worn belt or pulley can cause slippage and cause compressor overheating and other issues. It is also a good idea to drain the compressor on a regular basis. This will remove moisture that can cause corrosion to the motor and other components. A professional service team will check for leaks in the pipes, and ensure an adequate seal around the pressure sensor and compressor.
Finally, a pool of water in the vicinity of the compressor could be an indication of a leak in the refrigerant. This can be a dangerous problem and needs to be fixed immediately. If you suspect there is a leak, shut off the air compressor and call a professional.
Check the Thermostat
The thermostat is like the head of your HVAC system, and it’s no surprise that it’s the first thing that a technician will check when trouble arises. It’s also one of the most frequently neglected maintenance items, yet a properly maintained thermostat is vital to ensure your HVAC system’s operation. Examine your thermostat if you find inaccurate temperature readings, non-responsive controls, or continuous cycling.
Inaccurate Temperature Readings
Over time, the sensors on your thermostat may get dirty. This could cause it to display inaccurately. You can prevent these issues by ensuring the accuracy of your thermostat using a an additional thermometer.
A malfunctioning sensor, or a flawed calibration could cause your system to turn off and on in a continuous manner. This is known as short cycling. This can affect your comfort and result in unnecessary wear and tear to the compressor. These issues can be resolved by replacing the thermostat’s batteries or resetting the breakers.
Check the breakers for your HVAC equipment and thermostat 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 any signs of wear or damage. Check for dirt or dust and ensure that the thermostat isn’t too much exposed to sunlight. The fan blades must be inspected for any indications of rust or damage. This simple check will help avoid costly repairs in the future, and ensure that your equipment is running as smoothly as possible.
Basic maintenance of hvac is a great method to save energy and maintain comfort in your commercial building. It can also prolong the life of your cooling and heating equipment. By identifying problems with your thermostat, resetting the breaker, and then replacing the batteries in the process, you’ll be able keep your building cool all year. Remember to call an expert if you’re experiencing any other issues or aren’t sure what’s the issue with your system.
