The Importance of HVAC Maintenance
Maintenance is key when it comes to HVAC and cooling systems. It will help you avoid costly repairs or premature replacement. Most HVAC companies have a maintenance plan that allows you to pay an annual fee to have your system checked, repaired or cleaned as needed.
It’s also recommended to do a few DIY maintenance tasks throughout the year. Cleaning or replacing air filters, and keeping the area around the outdoor units free of debris will promote proper airflow.
Clean the Condenser
The coils of your condenser for your air conditioner are the primary component of the cooling process. If they’re dirty your system will be unable to cool properly and may even break down. Cleaning them is an important aspect of HVAC maintenance. It is relatively easy to accomplish. This easy DIY task will save you money, prevent costly repairs and prolong the life span of your air conditioner.
It is vital to cut off power from your unit before you disconnect it. You can do this by shutting off the breaker on your electrical box, or by turning off the outdoor unit disconnect switch. This will protect your electrical components and motors from being over-saturated during cleaning.
After the power has been shut off and you are able to remove any large debris obstructing the air condenser unit. This includes sweeping away any sticks, leaves, or other debris that has been accumulating on or around the unit. Utilizing a shop vacuum that has crevice attachments is a great method to get into the crevices and nooks and get rid of dust, dirt or other debris that may have accumulated.
The next step is to clean the coils. Be sure to have a few essential tools in your arsenal prior to beginning. Included in this are a coil cleaning concentrate, a pump up garden sprayer as well as an outdoor hose. Spray the coil cleaner in accordance with the directions on the product’s label and then rinse it off using the hose. It is essential not to apply excessive pressure when washing the coils, because the fins may be bent.
You should inspect the coils for signs of damage following cleaning. Over time, hail, stones thrown by lawnmowers, and other things can harm the coil fins. If the fins are bent, a cost-effective tool called a fin comb can straighten them to improve air flow and aid in the operation of the coils more efficiently.
When the fins and coils are in good shape If you are satisfied with the condition of your fins and coils, go back to your home and turn on your air conditioning. After around 24 hours, you can check the thermostat and make sure that the temperature is normal.
Cleaning the Ductwork
Your HVAC system works by bringing air from outside, cooling it and distributing it throughout your home. Air is transported from the evaporator in the condenser to your home’s registers and vents via a system duct. These ducts may become clogged with dust and other pollutants if they are not cleaned and sealed correctly. This could block air filters which can reduce the efficiency of your system and can strain your AC unit.
Cleaning the ductwork can be an extremely difficult job that requires specialized equipment and techniques. However, there are some actions you can take regularly to ensure that your ducts are clean and functioning well. First, you should change your filter on a regular basis to keep dust and allergens from accumulating in the ducts. This will also help keep clogs from occurring, which could lead to a reduced system efficiency and higher energy costs.
Cleaning the area around the vent openings is an additional way to keep your ducts cleaner. The hose attachment of your vacuum cleaner will get rid of all the crumbs, cobwebs and other debris that has built up over time. This will increase airflow through the vent. It is also important to ensure that your ducts are tightly sealed and insulated to keep out moisture which can lead to mold and other biological contaminants.
Ducts that are not cleaned on a regular basis can be filled with a wide variety of contaminants, including dust, pet dander, and pollen. These particles can trigger respiratory and allergies, especially for older people and children. The moisture in ductwork can 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 that you have your ducts cleaned every three to five years to remove these contaminates and ensure that your HVAC system functions effectively. If your ducts have been sealed well and you regularly change your filter, it may not be necessary to clean them. The best way to determine for sure is by having your ducts examined. An accredited contractor can use special testing methods to measure the amount of particles in your ductwork, and will recommend the appropriate cleaning schedules based on your particular situation.
Check the Compressor
The compressor is an essential element 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 lead to downtime for your equipment. Fortunately, preventive maintenance can help catch minor issues early and avoid excessive downtime. Regularly checking your unit can also help you save money by ensuring that your equipment is in good shape for as long as it is possible.
A common sign of a compressor problem is a loss in cooling capacity, but it could be caused by many different causes. A compressor may be working too hard due to inadequate airflow. This can cause wear on the bearings and reduce the life of the compressor. Another issue that is common is a blocked filter. If the filter is blocked it could reduce the airflow to the compressor and lead to overheating. To avoid this, it is crucial to clean or replace the filters on a regular basis, based on the manufacturer’s recommendations.
A blocked filter can cause a rattling sound in the compressor. This could indicate that the bearings need to be replaced. Regularly replacing the belts and pulleys is recommended. A loose pulley or belt could cause slipping and result in overheating of the compressor and other issues. It is recommended to drain the compressor regularly. This will eliminate moisture that can cause corrosion to the motor and other parts. A professional service team will also check for leaks in the hoses, and a tight seal on the pressure sensor and compressor.
A small puddle of water around the compressor can be an indication of a leak in the refrigerant. 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
The thermostat is kind of like the boss of your entire HVAC system, and it’s no surprise that it’s the first thing that a technician will look at when trouble arises. A properly maintained thermostat is essential for the efficient operation of your HVAC system. It’s one of the most neglected maintenance items. Common indicators that your thermostat needs periodic inspections include incorrect temperature readings, unresponsive controls, or constant cycling.
Inaccurate Temperature Readings
Thermostat sensors can become dirty over time, which can cause the device to display incorrectly. You can avoid this issue by checking the accuracy of your thermostat by using a the use of a separate thermometer.
A defective 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 could have a negative effect on your comfort and result in unnecessary wear and tears on the compressor. This issue can be solved by replacing the thermostat’s batteries or resetting the breaker.
If your system isn’t responding to your thermostat in any way, it’s an excellent idea to look at the breakers that control the thermostat and your HVAC equipment. If the breaker tripped, you will need to reset it in order for your thermostat to be able to communicate with the system.
It’s also important to check your thermostat for signs of wear or damage. Look for dust or dirt and make sure that the thermostat is not excessively exposed to the sun. Lastly, the fan blades should be checked for signs of damage or rust. This simple check will help avoid costly repairs in the future, and ensure that your equipment is running as smoothly as it can.
Basic maintenance of hvac is a great strategy to cut down on energy costs and keep your comfort in a commercial property. It also increases the life of heating and cooling equipment. You can ensure that your building stays comfortable throughout the year by identifying any issues with your thermostat, setting your breaker and replacing your batteries. Make sure to contact a professional if you are having any other problems or are unsure of what’s going on with your system.
