The Importance of HVAC Maintenance
Maintenance is key when it concerns HVAC and cooling systems. It will help you avoid costly repairs or premature replacement. Most HVAC companies have a service plan that allows you to pay an annual fee to have the system inspected and cleaned or repaired when needed.
It is also recommended to perform DIY maintenance throughout the year. Cleaning or replacing air filters, and keeping the area surrounding outdoor units clear of clutter will help ensure the proper airflow.
Clean the Condenser
The coils inside the condenser in your air conditioner are the core of the cooling process. If they’re dirty your system will be unable to cool properly and may even break down. This is why cleaning them is a crucial part of HVAC maintenance. It’s fairly easy to do. This simple DIY task will eliminate the need for expensive repairs, save you money on your energy bills, and prolong the longevity of your AC unit.
It is essential to disconnect power from your unit before you disconnect it. This can be accomplished by shutting off the breaker inside the electrical box, or by turning off the outdoor unit disconnect switch. This will prevent your motors and other electrical components from becoming oversaturated when cleaning.
After the power has been turned off, you can start taking down any large debris that could be hindering the condenser air. This includes sweeping off any sticks, leaves, or other debris that has accumulated around or on the unit. Utilizing a shop vacuum that has crevice attachments is a great method to get into the nooks and crevices and remove dust, dirt or other debris that has collected.
Next, it is time to clean the coils. Before doing this, though, make sure that you have in your possession several essential tools. Included in this are coil cleaning concentrates, a pump up garden sprayer, and an outdoor hose. Spray the coil cleaner in accordance with the instructions on the label, and then rinse it off using the water hose. When washing the coils it is important not to apply too much force as the fins are easily bent.
You should inspect the coils for signs of damage following cleaning. Over time hail, rocks thrown by lawnmowers and other things can harm the coil fins. If the fins are bent, a low-cost tool known as a fin-comb can straighten them to improve air flow and also to help the coils function more efficiently.
After you have a proper coil and fin setup then you can start your air conditioner. After about 24 hours, you can check the thermostat and ensure that the temperatures are in line with normal.
Clean the Ductwork
Your HVAC system is designed to bring air from outside into your home, then cool it and then distribute it throughout your home. Air is transported from the evaporator of your condenser unit to your home’s registers and vents through the system duct. These ducts can become clogged with dust and other pollutants when they aren’t maintained and sealed correctly. This can block the air filters, which in turn reduces system efficiency and puts strain on your AC unit.
In the majority of cases, cleaning the ductwork is not an easy task and requires professional equipment and methods. There are a few actions you can take regularly to keep your ducts tidy and in good working order. To prevent dust and allergens from building up in the ducts, you should change your filter frequently. This can also help prevent clogging, which can cause a decrease in efficiency and higher energy costs.
Vacuuming the area surrounding the vent openings is an additional way to keep your ducts in good shape. Using the hose attachment on your vacuum cleaner, you can get rid of all of the dust and crumbs that build up over time, and will aid in improving air flow through the vent. It’s also important to ensure that your ducts are sealed and insulated to keep out moisture which can lead to mold and other biological contaminants.
Ducts that aren’t regularly cleaned can become loaded with a variety of contaminants, such as dust, pet dander, and pollen. These particles can worsen respiratory and allergy conditions, particularly in the elderly and children. In addition, moisture in ductwork may lead to the growth of mold, which releases spores in the air and poses health concerns for those who suffer from respiratory issues.
It is generally recommended to have your ductwork cleaned every three to five years to remove these contaminates and ensure that your HVAC system is working efficiently. If your ducts have been sealed well and you change your filter regularly It may not be necessary to clean them. The best way to be able to tell the truth is to have your ducts examined. A licensed contractor can employ special testing methods to gauge the amount of particulates in your ductwork, and will suggest appropriate cleaning schedules that are based on your particular situation.
Check the Compressor
The compressor is an essential component of the system. It must function correctly to supply cool air to the ducts. If the compressor isn’t functioning as it should, this could affect your productivity and result in interruption to your equipment. Preventive maintenance can help identify minor issues earlier, avoiding unnecessary downtime. These routine checks will also save you money by ensuring that your equipment as efficient as possible.
A common sign of a compressor problem is a decrease in cooling capacity, however it could be caused by many different causes. A compressor may be working too hard due to poor airflow. This can wear out the bearings and diminish the lifespan of the compressor. Another common issue is a blocked filter. If the filter is clogged it can impede airflow to the compressor and cause overheating. It is crucial to change or clean the filters in accordance with the manufacturer’s guidelines.
A blocked filter can cause rattling sounds in the compressor. This could indicate that the bearings require to be changed. It is also a good idea to replace belts and pulleys on a regular basis. A belt or pulley that is loose can cause slippage and cause compressor overheating and other problems. It’s also a good idea to drain your compressor on a regular basis. This will remove the accumulated moisture that can corrode the motor and other components. A professional service team will also look for air leaks in the hoses, and ensure a tight seal between the compressor and pressure switch.
Lastly, a small puddle of water around the compressor can be a sign of a leak in the refrigerant. This can be a dangerous problem and needs to be fixed immediately. If you suspect that there is a leak, shut off the air compressor. Consult a professional.
Check the Thermostat
It’s not too surprising that a technician will check the thermostat first when there is any issue. A well-maintained thermostat is vital to the smooth operation of your HVAC system. It’s one of the most overlooked maintenance items. Common signs that your thermostat requires 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 incorrectly. Monitoring your thermostat’s accuracy regularly by using a separate thermometer can assist you in avoiding these issues and conserve energy.
A faulty sensor or calibration can also cause your system to keep switching on and off that is known as short cycling. This can affect your comfort, and cause unnecessary wear and tear to the compressor. These issues can be resolved by replacing the batteries in the thermostat or resetting the breakers.
Check the breakers for your HVAC and thermostat If your system isn’t responding to your thermostat. If the breaker has been tripped, it will have to be reset in order for the thermostat to be able to communicate with the system again.
It’s also crucial to examine your thermostat for signs of wear or damage. Examine for dust or dirt and make sure that the thermostat is not excessively exposed to the sun. Finally, the fan blades need to be examined for any indications of rust or damage. These simple checks can prevent costly repairs in the future, and ensure that your equipment is running as smoothly as it possibly can.
Basic maintenance of hvac is a great strategy to cut down on energy costs and maintain comfort in your commercial space. It can also prolong the life of cooling and heating equipment. By identifying any issues with your thermostat, setting the breaker and replacing the batteries in the process, you’ll be able keep your building warm all year round. Remember to call an expert if you’re having other issues or are unsure of what’s going on with your system.
