The Importance of HVAC Maintenance
Maintenance is key when it is concerned with heating and cooling systems. It will help you avoid costly repairs or premature replacement. The majority of HVAC companies offer a service plan that charges a low monthly rate to have your system checked, fixed or cleaned when required.
You should also perform 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 of the condenser of your air conditioner are the primary component of the cooling process. If they are dirty, your system will struggle to cool and may even breakdown. This is why cleaning them is a vital component of HVAC maintenance. It is, fortunately, relatively simple to complete. This simple DIY task will save you money, avoid expensive repairs and extend the lifespan 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 in the electrical box, or 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 clearing any large debris that could be hindering the condenser’s air. This includes cleaning up any sticks, leaves or other debris that has accumulated on or around the unit. Using a shop vacuum with a crevice attachment is a great option to reach into the crevices and nooks and get rid of any dust, dirt or other debris that may have accumulated.
The coils need to be cleaned. Make sure you 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 the garden hose. Spray the coil cleaner on in accordance with the directions on the product label and then rinse using the hose. It is important not to use too much pressure when washing the coils as the fins can easily be bent.
It is recommended to inspect 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. If the fins are bent, an affordable tool called a fin comb can straighten them to improve air flow and to aid in the operation of the coils more effectively.
Once you have a good coil and fin setup then you can turn on your air conditioner. Make sure to check the thermostat after 24 hours to confirm that temperatures are within the normal range.
Clean the Ductwork
Your HVAC system is able to bring air in from outside, cooling it, and then distributing it throughout your home. The air is transported from the evaporator in your condenser unit to your home’s registers, vents, and registers by the system of ducts. If these ducts aren’t cleaned and sealed, they may become loaded with dirt and other contaminates. This can block the air filters which reduces the effectiveness of your system as well as can strain your AC unit.
Cleaning ductwork can be a difficult task that requires expert equipment and methods. However, there are some things you can do regularly to ensure that your ducts remain clean and well-functioning. First, change your filter regularly to prevent dust and allergens from accumulating in the ducts. This can also help stop clogging, which could cause a decrease in efficiency and a higher cost for energy.
Another way to help keep your ducts clean is by regularly cleaning the area around vent openings. The hose attachment of your vacuum cleaner will remove all the crumbs, cobwebs and other messes that have accumulated over time. This will improve airflow through the vent. You should also make sure that your ducts have been sealed well and are insulated to prevent moisture from getting in, which could lead to mold and other biological contaminants.
If ducts are not cleaned regularly, they could build up a myriad of contaminants like dust, pet dander and pollen. These particles can trigger allergies and respiratory conditions, especially for older people and children. The moisture in ductwork can lead to the growth of mold which releases spores into the air and poses health concerns for those suffering from respiratory problems.
It’s generally recommended that you get your ductwork cleaned every three to five years to remove these contaminates and ensure that your HVAC system is working efficiently. However If your ducts are sealed and you change your filters regularly, duct cleaning may not be necessary at all. The best way to know the truth is to have your ducts examined. A contractor that is certified by the EPA will use special testing methods in order to determine the amount of particulates present in your ductwork. They will then suggest cleaning schedules that are appropriate for your particular situation.
Check the Compressor
The compressor is an essential component of the system. It must function properly to provide cool air to the ducts. If the compressor isn’t working as it should, it can affect your productivity and cause downtime for your equipment. However, preventive maintenance can assist in identifying issues that are minor and prevent unnecessary downtime. Performing these routine checks can also help you save money by ensuring that your equipment is in good shape for as long as possible.
A loss of cooling capacity is a common sign of a problem with the compressor. It could be caused by several different reasons. One possibility is that a compressor may be under-performing due to inadequate airflow. This can cause the bearings to wear out and decrease the life of the compressor. A clogged air filter is another common issue. If the filter has become clogged it can impede airflow to the compressor, which can cause overheating. It is important to clean or change the filters according to the manufacturer’s instructions.
A blocked filter could cause a sound of rattling in the compressor. This could be an indication that the bearings require to be replaced. Regularly replacing the belts and pulleys is recommended. A worn belt or pulley could cause slipping and result in compressor overheating and other problems. It is also a great 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 will also examine for air leaks within the hoses and an adequate seal between the compressor and pressure switch.
A puddle of liquid close to the compressor could be an indicator of an issue. This is a risky issue that needs to be addressed immediately. If you suspect that there is a leak, switch off the compressor that is running and then contact an expert.
Check the Thermostat
The thermostat is kind of like the head of your entire HVAC system, so it’s not surprising that it’s the first thing that a technician will check when trouble arises. A properly maintained thermostat is essential for the proper operation of your HVAC system. It’s one of the most overlooked maintenance items. The most common signs that your thermostat requires periodic inspections include incorrect temperature readings, non-responsive controls, or continuous cycling.
Inaccurate Temperature Readings
Over time the sensors on your thermostat can become dirty. This could cause it to display in a wrong manner. You can prevent these issues by checking the accuracy of your thermostat with a separate thermometer.
A defective sensor or a faulty calibration can cause your system to cycle on and off constantly. This is referred to as short cycling. This could have a negative effect on your comfort and cause unnecessary wear and tears on the compressor. These issues can be resolved by replacing the batteries in the thermostat or resetting the breakers.
If your system isn’t responding to your thermostat at all it’s an excellent idea to look at the breakers that control the thermostat as well as 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 crucial to examine your thermostat for any signs of wear or damage. Check for dirt or dust and ensure that the thermostat isn’t excessively exposed to the sun. Examine the fan blades for signs of rust and damage. These simple checks can prevent costly repairs in the future and will ensure that your equipment operates as smoothly as possible.
Basic HVAC maintenance is a great method to reduce energy costs and maintain comfort in your commercial property. It will also extend the life of cooling and heating equipment. By identifying issues with your thermostat, resetting the breaker and replacing the batteries in the process, you’ll be able keep your building cool all year. Make sure that if you have any other issues, or are unsure of what’s wrong with your system you should always consult a professional.
