The Importance of HVAC Maintenance
Maintenance is key when it is concerned with HVAC and cooling systems. It will allow you to avoid costly repairs or premature replacement. Most HVAC companies offer a service plan that you pay the monthly cost to have your system checked out, fixed or cleaned as necessary.
You should also carry out some DIY maintenance throughout the year. This includes 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 your air conditioner condenser are the primary component of the cooling process. If they are dirty, you system will struggle to cool, and it could even breakdown. Cleaning them is an important component of HVAC maintenance. It’s also relatively simple to complete. This easy DIY task will eliminate the need for costly repairs, save you money on your energy bills, and extend the life of your air conditioning unit.
In the beginning, it is crucial to shut off the power supply to your unit. This can be accomplished by turning off the breaker in your electrical box or by turning off the outdoor unit disconnect switch. This will stop your motors and other electrical components from becoming oversaturated when cleaning.
When the power is turned off and you are able to clean up any large debris obstructing the air condenser unit. This includes sweeping up any sticks, leaves, or other debris that have built up around or on the unit. A shop vacuum equipped with crevice attachments is a great way to get into the crevices and nooks and get rid of any dirt, dust or other debris that has collected.
The next step is to clean the coils. Before you begin, though, make sure you have some essential tools. These will include a coil cleaner concentrate and a pump-up garden sprayer and a garden hose. Spray the coil cleaner in accordance to the directions on the label, then rinse it off using the garden hose. When washing the coils it is important to not use too much force since the fins can be bent easily.
You should examine the coils for signs of damage after cleaning. Over time hail or rocks thrown by lawnmowers and other items can damage the coil’s fins. Fin combs can be used to straighten bent fins to ensure better airflow and coil performance.
After you have a proper coil and fin set up, you can start your air conditioner. Check the thermostat every 24 hours to ensure the temperatures are in good shape.
Cleaning the Ductwork
Your HVAC system works to bring air from outside into your home, 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 via the system duct. These ducts may become clogged with dust and other pollutants when they aren’t cleaned and sealed correctly. This can clog the air filters which can reduce the effectiveness of your system as well as can strain your AC unit.
In the majority of cases, cleaning the ductwork isn’t an easy task that requires professional equipment and techniques. There are a few things you can do to keep your ducts tidy and in good working order. To stop dust and allergens from building up in the ducts, it is recommended to change your filter frequently. This also helps to keep the clogs from occurring which can lead to reduced system efficiency and high energy bills.
Another way to keep your ducts clean is to regularly cleaning the area around the vent openings. By using the hose attachment on your vacuum cleaner can remove all cobwebs and crumbs which accumulate over time, and help to improve air flow through the vent. It is also important to ensure that your ducts are sealed tight and protected from moisture getting in, which could cause mold and other biological contaminants.
Ducts that aren’t regularly cleaned are likely to be contaminated with a myriad of contaminants, such as dust, pet dander and pollen. These particles can cause a flare-up of respiratory issues and allergies, especially in children and the elderly. Moisture can also cause mold to develop in ductwork, which releases spores that are harmful to those with respiratory problems.
It’s generally recommended that you get your ductwork cleaned every three to five years to remove these contaminants and ensure your HVAC system is working efficiently. If your ducts are sealed well and you change your filter regularly, it may not be necessary to clean them. The best way to determine for sure is by having your ducts examined. A licensed contractor can employ special testing methods to gauge the amount of particles in your ductwork, and can recommend suitable cleaning schedules based upon your specific situation.
Check the Compressor
The compressor is a crucial element of the system. It needs to operate correctly to supply cool air to the ducts. If the compressor isn’t working in the way it should, it can affect your productivity and cause equipment downtime. Regular maintenance can help you identify small issues early, preventing unnecessary downtime. Regularly checking your unit can also save you money by keeping your unit in good shape for as long as is possible.
A common sign of a compressor issue is a reduction in cooling capacity, however this could be due to many different causes. One possibility is that the compressor may be working too hard due to poor airflow. This can wear out the bearings and diminish the lifespan of the compressor. A clogged air filter is another frequent issue. If the filter has become clogged it could reduce the airflow to the compressor, which can cause overheating. To prevent this, it is important to clean or change the filters frequently, according to the manufacturer’s recommendation.
In addition, a clogged filter can also cause rattling noises in the compressor. This could indicate that the bearings require to be changed. It is also a good idea to replace belts and pulleys regularly. A pulley or belt that is loose can cause the compressor to overheat and create other problems. It is recommended to drain the compressor on a regular basis. This can remove accumulated moisture that could cause corrosion to the motor and other components. A professional service team will examine for leaks in pipes, and ensure an adequate seal around the compressor and pressure sensor.
Lastly, a small puddle of water around the compressor can be an indication of a leak in the refrigerant. This is a potentially dangerous problem that should be addressed immediately. If you suspect that there is a leak, shut off the compressor that is running and then contact a professional.
Check the Thermostat
The thermostat is kind of like the boss of your HVAC system, so it’s no surprise that it’s the first thing a technician will check when trouble arises. It’s also one of the most frequently neglected maintenance items, but a properly maintained thermostat is crucial for ensuring your HVAC system’s operation. Check your thermostat if notice incorrect temperature readings, unresponsive controls, or constant cycling.
Inaccurate Temperature Readings
Over time, the sensors on your thermostat may get dirty. This can cause it to display incorrectly. You can prevent these issues by checking the accuracy of your thermostat by using a the use of a separate thermometer.
A malfunctioning sensor or calibration could result in your system constantly switching on and off, which is referred to as short cycling. This can have a negative impact on your comfort as well as cause excessive wear and tear on the compressor. Fortunately this can be resolved with the simple act of 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 tripped it, you’ll need to reset it in order for your thermostat to communicate again with the system.
Check your thermostat for indications of wear and tear. Find signs of dirt or dust and ensure that the thermostat isn’t overly exposed to sunlight. The fan blades need to be examined for any signs of damage or rust. This simple check will help avoid costly repairs in the future, and ensure that your equipment runs as smoothly as possible.
The simple maintenance of hvac systems on your commercial property is an excellent method to cut energy consumption, ensure comfort and prolong the lifespan of your cooling and heating equipment. By identifying any issues with your thermostat, resetting the breaker and replacing the batteries in the process, you’ll be able keep your building cool all year. Be sure to call a professional if you have any other issues or aren’t sure the issue you should always consult a professional.
