The Importance of HVAC Maintenance
Maintenance is key when it comes to HVAC and cooling systems. It will allow you to avoid costly repairs or premature replacement. The majority of HVAC companies have a service plan that allows you to pay a monthly fee to have your system checked, repaired or cleaned as required.
It’s also a good idea to perform some DIY maintenance tasks throughout the year. Cleaning or replacing air filters and keeping the area surrounding outdoor units clear of any debris will ensure the proper airflow.
Clean the Condenser
The coils in the condenser of your air conditioner are at the heart the cooling process. If they’re dirty, your system will struggle to cool properly and may even fail to function properly. Cleaning them is an essential part of HVAC maintenance. It’s fairly easy to complete. This easy DIY task will eliminate the need for expensive repairs, and save you money on your energy bills and extend the life of your air conditioning unit.
It is the first step. It is crucial to shut off the power supply 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 keep your motors and other electrical components from becoming oversaturated during cleaning.
After the power has been shut off and you are able to clear any large debris that is blocking the air condenser unit. This means taking away any sticks, leaves, or other debris that has accumulated on or around the unit. A shop vacuum with crevice tools is an excellent 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, ensure that you have in your possession several essential tools. These will include a concentrate for coil cleaning, a pump-up garden sprayer and a garden hose. Spray the coil cleaner according to the directions on the label, then rinse with a hose. It is important not to use excessive pressure when washing the coils, as the fins can easily be bent.
You should inspect the coils for signs of damage following cleaning. Over time, hail and rocks thrown by lawnmowers and other items can damage the coil’s fins. If the fins are bent, a cost-effective tool known as a fin-comb can straighten them for better air flow and to aid in the operation of the coils more effectively.
When you have a great coil and fin set up then you can turn on your air conditioner. After around 24 hours, you can examine the thermostat and make sure that the temperature is normal.
Clean the Ductwork
Your HVAC system is designed to bring air from outside into your home, cool it, and then distribute it throughout your home. The air travels from the evaporator coil in your condenser unit and then to your house’s vents and registers through a system of ducts. If the ducts aren’t cleaned and sealed, they may be laden with dust and other contaminants. This can block the air filters which reduces the efficiency of your system and puts strain on your AC unit.
Cleaning the ductwork can be a difficult task that requires professional equipment and methods. However, there are some actions you can take regularly to ensure that your ducts remain clean and well-functioning. First, make sure you change your filter regularly to prevent dust and allergens from accumulating up in the ducts. This will also help to keep the clogs from occurring which can cause a decrease in system efficiency and high energy bills.
Vacuuming the area around the vent openings is another way to keep your ducts clean. The hose attachment of your vacuum cleaner will remove all the cobwebs, crumbs and other messes that have accumulated over time. This will increase airflow through the vent. Also, make sure that your ducts have been 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 accumulate a variety of contaminants like dust, pet dander, and pollen. These particles can trigger allergies and respiratory conditions, especially for children and the elderly. Moisture in ductwork can also lead to the growth of mold which releases spores into air and can cause health issues for those suffering from respiratory problems.
It is generally recommended to have your ductwork cleaned every three to five years in order to eliminate the toxins and ensure that your HVAC system functions efficiently. If your ducts are sealed well and you replace your filter on a regular basis it might not be necessary to clean them. The best way to know for certain is to have your ducts tested. An accredited contractor can use specific testing methods to determine the amount of particulates in your ductwork and can recommend suitable cleaning schedules based upon the specific circumstances.
Check the Compressor
The compressor is a critical component of the system. It has to be able to deliver cool air into the ducts. If the compressor isn’t operating as it should it could affect your productivity and cause equipment downtime. Fortunately, preventive maintenance is able to assist in identifying issues that are minor and avoid excessive downtime. Performing these routine checks can also save you money by keeping your unit in good shape for as long as is possible.
The most common sign of a compressor issue is a decrease in cooling capacity, but it could be caused by many different causes. One possibility is that a compressor may be under-performing due to inadequate airflow. This can wear out the bearings and reduce the lifespan of the compressor. Another issue that is common is a clogged filter. If the filter has become clogged it could reduce the airflow to the compressor and cause overheating. It is essential to change or clean the filters in accordance with the manufacturer’s recommendations.
Additionally, a blocked filter could also cause rattling noises in the compressor. This can indicate that the bearings are worn out and must be replaced. It is recommended to replace pulleys and belts regularly. A belt or pulley that is loose can cause slippage and cause compressor overheating and other issues. It’s also a good idea to drain your compressor regularly. This will remove the accumulated moisture that can corrode the motor and other components. A professional service team can examine for air leaks within the hoses as well as an adequate seal between the compressor and pressure switch.
Lastly, a small puddle of water around the compressor could be a sign of a refrigerant leak. This is a potentially dangerous issue that needs to be addressed immediately. If you suspect a leak, shut off the air compressor. Consult a professional.
Check the Thermostat
It’s not too surprising that technicians will always look at the thermostat first when there is a problem. It’s also one of the most commonly overlooked maintenance items, but maintaining your thermostat properly is essential to ensure your HVAC system’s optimal operation. Common indicators that your thermostat is in need of periodic inspections include incorrect temperature readings, ineffective controls, or continuous cycling.
Inaccurate Temperature Readings
Over time, the thermostat’s sensors can get dirty. This could cause it to display in a wrong manner. Monitoring your thermostat’s accuracy regularly by using a separate thermometer can assist you in avoiding these issues and help you save energy.
A faulty sensor or calibration can also lead to your system continuously switching on and off this is known as short cycling. This can affect your comfort and cause unnecessary wear and tear on the compressor. The problem can be fixed by simply replacing the thermostat’s batteries or resetting the breaker.
Make sure you check the breakers on both your HVAC equipment and thermostat If your system isn’t responding to your thermostat. If the breaker has been tripped, it will require resetting to allow the thermostat to communicate with the system again.
It is also essential to examine your thermostat for signs of wear or damage. Examine for dust or dirt and ensure that the thermostat is not too much exposed to sunlight. Examine the fan blades to find evidence of damage or rust. These simple checks will prevent costly repairs in the future and will ensure that your equipment is running as smoothly as possible.
The simple maintenance of hvac systems on your commercial property is a great way to reduce energy consumption, ensure comfort and prolong the longevity of your cooling and heating equipment. By identifying problems with your thermostat, setting the breaker and replacing the batteries, you’ll be able to keep your building cool all year. Be sure to call a professional if you are having any other problems or unsure of what is wrong with your system.
