The Importance of HVAC Maintenance
Maintenance is essential when it comes to heating and cooling systems. It will allow you to avoid costly repairs or premature replacement. The majority of HVAC companies have a service plan that charges a monthly fee to have the system checked and cleaned or repaired when needed.
It’s also an excellent idea to carry out a few DIY maintenance tasks throughout the year. These include cleaning or replacing air filters, and keeping the space around outdoor units free of debris to promote the proper airflow.
Clean the Condenser
The coils in the condenser of your air conditioner are the primary component of the cooling process. If they’re dirty, your system will struggle to cool, and it could even fail. Cleaning them is a crucial component of HVAC maintenance. It’s also fairly easy to do. This simple DIY task will eliminate the need for expensive repairs, save you money on your energy bills, and extend the longevity of your AC unit.
It is the first step. It is important to disconnect the power to your unit. This can be accomplished by turning off the breaker inside your electrical box or at the outdoor unit disconnect switch. This will stop your motors and other electrical components from being oversaturated during cleaning.
After the power has been turned off, you can start removing any large debris that could be hindering the air condenser. This means sweeping off any sticks, leaves or other debris that have accumulated around or on the unit. Using a shop vacuum with a crevice attachment is a great way to reach into the crevices and nooks and get rid of dust, dirt or other debris that has accumulated.
Next, it is time to clean the coils. Make sure you have a few essential tools in your arsenal prior to beginning. These will include a coil cleaner concentrate, a pump-up garden sprayer and a garden hose. Spray the coil cleaner according to the directions on the label, and then rinse it off with the hose. It is essential not to apply too much 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, hail and rocks that are thrown by lawnmowers and other objects can cause damage to coil fins. Fin combs can be utilized to straighten bent fins for better airflow and performance of the coil.
Once you have a good coil and fin set up, you can start your air conditioner. After around 24 hours, you should check the thermostat and make sure 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 home. The air moves from the evaporator coil of your condenser unit and then to the vents and registers of your home through a duct system. If these ducts aren’t cleaned and sealed, they can be laden with dust and other contaminants. This clogs the air filters, which in turn reduces the efficiency of your system and puts strain on your AC unit.
Cleaning the ductwork can be a challenging task that requires specialized equipment and techniques. But, there are things you can do regularly to make sure your ducts stay clean and functioning well. First, you should change your filter on a regular basis to keep dust and allergens out of building in the ducts. This can also help prevent clogging, which can cause a decrease in efficiency and a higher cost for energy.
Another way to keep your ducts tidy is to regularly cleaning the area around vent openings. Using the hose attachment on your vacuum cleaner, you can eliminate all of the cobwebs and crumbs which accumulate over time, and assist in improving airflow through the vent. It’s also important to ensure that your ducts are tightly sealed and sealed with insulation to keep out moisture, which can lead to mold and other biological contaminants.
If ducts are not regularly cleaned, they may accumulate a variety of contaminants like dust, pet dander, and pollen. These particles can exacerbate respiratory and allergy conditions especially for children and the elderly. Moisture in ductwork can also result in the growth of mold, which releases spores in the air and poses health concerns for those suffering from respiratory ailments.
It’s 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 are sealed properly, and you regularly change your filter It may not be necessary to clean them. The best way to be able to tell for sure is by having your ducts examined. A contractor accredited by the EPA can employ special testing methods in order to measure the amount particulates present in your ductwork. They will then recommend cleaning schedules that are suitable for your specific situation.
Check the Compressor
The compressor is a critical element of the system. It has to function properly to provide cool air to the ducts. If the compressor isn’t operating as it should and isn’t functioning properly, it could impact your productivity and result in the equipment to shut down. Regular maintenance can help you identify minor issues earlier, avoiding excessive downtime. These routine checks will also save you money by keeping your unit as good as possible.
A loss of cooling capacity is a common sign of a problem in the compressor. It could be caused by a variety of causes. One possibility is that the compressor may be working too hard due to poor airflow. This can cause bearings to wear down and decrease the life of the compressor. Another common issue is a clogged filter. Filters that are clogged can hinder airflow and cause the compressor to overheat. To prevent this from happening, it is important to clean or change the filters regularly based on the recommendations of the manufacturer.
In addition, a clogged filter may also cause rattling noises in the compressor. This could be an indication that the bearings need to be replaced. It is recommended to replace pulleys and belts regularly. A loose pulley or belt could cause slipping and result in compressor overheating and other issues. It is also a good idea to drain your compressor on a regular basis. This will remove moisture that can cause corrosion to the motor and other components. A professional service team can also look for air leaks in the hoses and an adequate seal between the compressor and pressure switch.
A puddle of liquid close to the compressor could be an indication of an issue. This is a risky problem that must be dealt with immediately. If you suspect there is a leak, switch off the air compressor and call an expert.
Check the Thermostat
It’s not surprising that technicians will always check the thermostat first when there is an issue. It’s also among the most often neglected maintenance items, yet a properly maintained thermostat is crucial for ensuring your HVAC system’s optimal operation. The most common signs that your thermostat needs periodic inspections include incorrect temperature readings, non-responsive controls, or continuous cycling.
Inaccurate Temperature Readings
Thermostat sensors can get dirty over time, which can cause the thermostat to display incorrectly. You can avoid these problems by checking the accuracy of your thermostat with the use of a separate thermometer.
A faulty sensor, or a faulty calibration can cause your system to turn off and on in a continuous manner. This is called short cycling. This could have a negative effect on your comfort and cause excessive wear and tear on the compressor. Fortunately the majority of these issues can be resolved with simply replacing the batteries in your thermostat or resetting the breaker.
If your thermostat isn’t responding to your thermostat at all it’s a good idea to check the breakers that control the thermostat and your HVAC equipment. If the breaker has tripped, it will need to be reset in order for the thermostat to connect with the system.
It’s also important to check your thermostat for signs of wear or damage. Examine for dust or dirt and ensure that the thermostat is not overly exposed to the sun. Examine the fan blades for evidence of damage or rust. These simple checks will prevent costly repairs in the future and ensure that your equipment operates as smoothly as possible.
Basic maintenance of hvac is a great method to reduce energy costs and keep your comfort in a commercial property. It will also extend the life of heating and cooling equipment. You can ensure that your building stays cool throughout the year by identifying any issues with your thermostat, setting your breaker and replacing your batteries. Just remember that in case you experience any other issues or are unsure about what’s wrong with your system you should always consult a professional.
