The Importance of HVAC Maintenance
Maintenance is crucial when it is concerned with HVAC and cooling systems. It can help you avoid costly repairs or premature replacement. Most HVAC companies offer a service plan where you pay a low monthly rate to get the system checked out, fixed or cleaned when required.
You should also carry out some DIY maintenance throughout the year. Cleaning or replacing air filters and keeping the area surrounding outdoor units free of any debris will ensure proper airflow.
Clean the Condenser
The coils inside the condenser of your air conditioner are the heart of the cooling process. If they are dirty the system will be unable to cool properly and may even fail to function properly. Cleaning them is an essential part of HVAC maintenance. Fortunately, it is also quite simple to do. This simple DIY task will save you money, avoid expensive repairs and extend the lifespan of your air conditioner.
In the beginning, it is important to disconnect the power source to your unit. This can be accomplished by shutting off the breaker inside your electrical box or by turning off the outdoor unit disconnect switch. This will protect your electrical components and motors from being flooded when cleaning.
When the power is turned off it is now time to remove any large debris obstructing the air condenser unit. This means sweeping up any leaves, sticks, or other debris that has built up on or around the unit. A shop vacuum with a crevice tool is an excellent way to reach into the nooks, crannies and remove dust or dirt that has built up.
Next, it is time to clean the coils. Before you begin, though, make sure that you have on-hand a few key tools. These will include a concentrate of the coil cleaner, a pump-up garden sprayer and a garden hose. Spray the coil cleaner according to the directions on the product label and then rinse using the hose. When washing the coils, it is important not to apply excessive force since the fins can bend easily.
After the coils have been cleaned, look them over for any signs of damage. Over time, hail and rocks thrown from lawnmowers or other items can damage coil fins. If the fins are bent, a cost-effective tool known as a fin-comb can straighten them to improve air flow and assist in ensuring that the coils operate more efficiently.
If the fins and coils are in good shape, you can return to your house and switch on your air conditioning. After about 24 hours, you can check the thermostat and make sure that temperatures are normal.
Cleaning the Ductwork
Your HVAC system works by bringing air in from outside, cooling it and then distributing it throughout your home. The air is transported from the evaporator of your condenser to your home’s registers, vents, and registers by the system ducts. If the ducts aren’t cleaned and sealed, they may become clogged with dust and other contaminants. This can block the air filters and reduces the efficiency of your system and puts strain on your AC unit.
Cleaning the ductwork can be an extremely difficult job that requires expert equipment and methods. However, there are a few things you can do on a regular basis to ensure that your ducts remain clean and well-functioning. To avoid dust and allergens accumulating in the ducts, you should change your filter on a regular basis. This will also help to prevent clogging, which can lead to a reduced system efficiency and higher energy costs.
Another method to keep your ducts clean is by regularly cleaning the area around the vent openings. Using the hose attachment on your vacuum cleaner can remove all the dust and crumbs that build up over time, and will aid in improving airflow through the vent. It is also essential to ensure that your ducts are sealed and sealed with insulation to keep out moisture which can cause mold and other biological contaminants.
If ducts aren’t cleaned regularly, they could accumulate a variety of contaminants such as dust, pet dander, and pollen. These particles can cause allergies and respiratory issues especially for children and the elderly. Moisture in ductwork can also result in the growth of mold which releases spores into the air and can cause health issues for those suffering from respiratory issues.
It is recommended to clean your ducts once every three to five years to remove these contaminants and ensure that your HVAC system is functioning efficiently. However it is possible that if your ducts are well-sealed and you regularly change your filters, duct cleaning may not be necessary at all. The best way to know the truth is to have your ducts tested. A contractor that is certified by the EPA can employ special testing techniques to measure the amount particulates that are present in your ductwork. They can then recommend cleaning schedules that are suitable for your situation.
Check the Compressor
The compressor is a critical component of the system. It has to be able to provide cool air to the ducts. If the compressor isn’t functioning in the way it should and isn’t functioning properly, it could impact your productivity and lead to the equipment to shut down. Preventive maintenance can help identify minor issues early, preventing excessive downtime. Conducting these regular checks can also help you save money by ensuring that your equipment is in good working order for as long as it is possible.
A decrease in cooling capacity is a common sign of a problem with a compressor. It could be caused by several different factors. One possibility is that a compressor could be working too hard due to poor airflow. This could cause the bearings to wear down and decrease the life of the compressor. A clogged air filter is another common issue. Filters that are blocked can restrict airflow and cause the compressor to overheat. It is crucial to change or clean the filters according to the manufacturer’s instructions.
In addition, a clogged filter can also cause rattling noises in the compressor. This could indicate that the bearings must be changed. It is also a good idea to replace pulleys and belts regularly. A loose belt or pulley can slip, causing the compressor to overheat and create other issues. It is also a good idea to drain the compressor regularly. This will remove the moisture that could 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 the pressure switch.
Lastly, a pool of water in the vicinity of the compressor could be a sign of a refrigerant leak. This is a serious issue and should be repaired immediately. If you suspect there is a leak, shut off the air compressor and call an expert.
Check the Thermostat
The thermostat is kind of like the head of your HVAC system, so it’s not surprising that it’s the first thing a technician will look at when trouble arises. A well-maintained thermostat is vital to the efficient operation of your HVAC system. It’s among the most frequently neglected maintenance items. Check your thermostat if you notice incorrect temperature readings, non-responsive controls, or constant cycling.
Inaccurate Temperature Readings
Over time the thermostat’s sensors can get dirty. This can cause it to display incorrectly. Regularly checking the accuracy of your thermostat with a separate thermometer will assist you in avoiding these issues and help you save energy.
A faulty sensor or calibration may cause your system to keep turning on and off this is known as short cycling. This can adversely affect your comfort and result in unnecessary wear and tear on the compressor. These issues can be resolved by replacing the batteries in the thermostat or resetting the breakers.
If your thermostat isn’t responding to your thermostat in any way it’s a good idea to check the breakers that regulate the thermostat as well as your HVAC equipment. If the breaker has been tripped, it will require resetting to allow the thermostat to communicate with the system.
Check your thermostat for signs of wear and damage. Check for dirt or dust and ensure that the thermostat is not excessively exposed to the sun. Check the fan blades for signs of rust and damage. These simple checks can prevent expensive repairs in the future, and help ensure that your equipment is running as smoothly as it is possible.
Basic maintenance of hvac is a great way to reduce energy costs and maintain comfort in your commercial property. It can also prolong the lifespan of heating and cooling equipment. It is possible to keep your building comfortable throughout the year by identifying issues with your thermostat, then resetting your breaker and changing your batteries. Just remember that in case you experience any other issues or are unsure of what’s wrong with your system you should always consult a professional.
