The Importance of HVAC Maintenance
Maintenance is crucial when it concerns HVAC and cooling systems. It will allow you to avoid costly repairs or premature replacement. The majority of HVAC companies offer a maintenance plan that you pay a low monthly rate to have your system checked, fixed or cleaned if required.
It’s also a good idea to perform some of the DIY maintenance tasks throughout the year. This includes cleaning or replacing air filters and keeping the space around outdoor units free of debris to promote the proper flow of air.
Clean the Condenser
The coils that make up the condenser of your air conditioner are the core of the cooling process. If they are dirty the system will be unable to cool properly and may even break down. Cleaning them is a crucial part of HVAC maintenance. It’s relatively simple to complete. This simple DIY task will help you save money, avoid costly repairs and prolong the lifespan of your air cooling.
It is essential to disconnect power from your unit first. 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 getting overloaded while cleaning.
After the power has been shut off, you can start taking down any large objects that could be hindering the condenser air. This includes cleaning off any sticks, leaves, or other debris that have accumulated around or on the unit. A shop vacuum with a crevice tool is a great tool to get into the crevices, nooks, and loosen dust or dirt that has been accumulating.
The coils must be cleaned. Be sure to have the necessary tools in your arsenal before you begin. This will include a concentrate of the coil cleaner, a pump-up garden sprayer and a garden hose. Spray the coil cleaner in accordance with the directions on the product’s label and then rinse it off using the hose. When washing the coils it is essential not to use excessive force since the fins are easily bent.
It is recommended to inspect the coils for signs of damage following cleaning. Over time, the impact of hail and stones thrown from lawnmowers or other items could damage the coil fins. If the fins are bent, an affordable tool called a fin comb can straighten them for better air flow and also to help the coils function more effectively.
If 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. Make sure to check the thermostat after 24 hours to ensure the temperatures are in good shape.
Cleaning the Ductwork
Your HVAC system works by bringing air in from outside, cooling it, and then distributing it throughout your home. Air is moved from the evaporator of the condenser to your home’s registers and vents through the system of ducts. If the ducts aren’t cleaned and sealed, they could become loaded with dust and other pollutants. This clogs the air filters, which in turn reduces system efficiency and strains your AC unit.
In the majority of cases, cleaning the ductwork isn’t an easy task and requires professional equipment and techniques. However, there are some actions you can take on a regular basis to ensure that your ducts remain clean and functioning well. To avoid dust and allergens from accumulating in the ducts, you should change your filter frequently. This also helps to prevent the clogging that can cause a decrease in system efficiency and a high energy bill.
Vacuuming the area around the vent openings is another method to keep your ducts in good shape. The hose attachment on your vacuum cleaner will get rid of all the cobwebs, crumbs and other debris that has built up 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 result in mold and other biological contaminants.
If ducts aren’t cleaned regularly, they can build up a myriad of contaminants like dust, pet dander and pollen. These particles can cause respiratory and allergy conditions particularly in children and the elderly. Moisture can cause mold to grow in ductwork, which releases the spores that can be harmful to those suffering from respiratory ailments.
It’s generally recommended that you have your ducts cleaned every three to five years in order to eliminate these contaminates and ensure that your HVAC system functions efficiently. If your ducts are well-sealed, and you regularly change your filter it might not be necessary to clean them. You can only be certain that your ducts are in good condition by having them checked. A contractor that is certified by the EPA will use special testing techniques to determine the amount of particulates present in your ductwork. They will 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 function properly to provide cool air to the ducts. If the compressor isn’t operating properly, it can affect your productivity and result in interruption to your equipment. Preventive maintenance can help spot minor issues early, preventing excessive downtime. These regular checks will also save you money by keeping your equipment as efficient as possible.
The most common sign of a compressor issue is a loss in cooling capacity, but it could be caused by a number of different factors. One possibility is that a compressor may be working too hard due to poor airflow. This could cause the bearings to wear out and decrease the life of the compressor. Another issue that is common is a blocked filter. Filters that are clogged can reduce airflow and cause the compressor to overheat. It is crucial to clean or change the filters in accordance with the manufacturer’s instructions.
A clogged filter may also cause a sound of rattling in the compressor. This could mean that the bearings are wearing out and must be replaced. It is recommended to replace pulleys and belts on a regular basis. A worn-out belt or pulley can slip, causing the compressor to overheat and cause other problems. It is recommended to drain the compressor on a regular basis. This will remove moisture that can cause corrosion to the motor and other components. A professional service team can examine for air leaks within the hoses as well as an adequate seal between the compressor and pressure switch.
A puddle of liquid near the compressor could be an indication of a leak. This can be a dangerous problem and needs to be fixed immediately. If you suspect that there is a leak, turn off the air compressor. Get a professional to assist you.
Check the Thermostat
It’s not a surprise that a technician will always look at the thermostat first when there’s any issue. It’s also one of the most commonly overlooked maintenance items, yet maintaining your thermostat properly is essential to ensure your HVAC system’s optimal operation. The most common signs that your thermostat needs an inspection include inaccurate temperature readings, unresponsive controls, or continuous cycling.
Inaccurate Temperature Readings
Thermostat sensors can become dirty over time, which can cause the device to display incorrectly. Regularly checking the accuracy of your thermostat with a separate thermometer will assist you in avoiding these issues and save energy.
A malfunctioning sensor, or a flawed calibration could cause your system to cycle on and off continuously. This is known as short cycling. This could have a negative effect on your comfort as well as cause excessive wear and tear on the compressor. Fortunately the majority of these issues can be corrected by simply replacing the thermostat’s batteries or resetting the breaker.
Check the breakers for both your HVAC and thermostat in the event that your HVAC equipment doesn’t respond to your thermostat. If the breaker has been tripped, it will need to be reset to allow the thermostat to connect with the system once more.
Check your thermostat for indications of wear and tear. Check for indications of dust or dirt, and make sure the thermostat isn’t overly exposed to sunlight. The fan blades must be inspected for indications of rust or damage. These simple checks can help avoid expensive repairs in the future, and will ensure that your equipment is operating as efficiently as it can.
Basic maintenance of hvac is a great method to reduce energy costs and ensure comfort in your commercial building. It also increases the life of your cooling and heating equipment. By identifying issues with your thermostat, resetting the breaker, and then replacing the batteries, you’ll be able to keep your building cool all year. Make sure to contact an expert if you’re having other issues or unsure of what is the issue with your system.
