The Importance of HVAC Maintenance
When it comes to your heating and cooling system, regular maintenance is the key to avoiding costly repairs or early-than-necessary replacement. Most HVAC companies have a service plan that allows you to pay each month to have the system checked and cleaned or repaired when needed.
It’s also a good idea to perform a few DIY maintenance tasks throughout the year. This includes cleaning or replacing air filters, and keeping the area around outdoor units free of clutter to allow for the proper airflow.
Clean the Condenser
The coils of the condenser of your air conditioner are at the heart the cooling process. If they are dirty the system will struggle to cool properly and could even fail. Cleaning them is an essential component of HVAC maintenance. It’s relatively simple to complete. This easy DIY task will eliminate the need for expensive repairs, save you money on your energy bills and prolong the lifespan of your air conditioning unit.
First and foremost, it is important to disconnect the power to your unit. You can do this by turning off the breaker at your electrical box, or by turning off the outdoor unit disconnect switch. This will stop your motors and other electrical components from becoming oversaturated during cleaning.
After the power has been shut off, you can start clearing any large debris that may be blocking the condenser’s air. This means taking away any sticks, leaves or other debris that has been accumulating on or around the unit. Using a shop vacuum with crevice attachments is a great way to reach into the nooks and crannies and loosen any dirt, dust or other debris that may have accumulated.
The coils need to be cleaned. Before doing this however, make sure that you have in your possession a few key tools. This will include a concentrate for coil cleaning, a pump-up garden sprayer and a garden hose. Spray the coil cleaner according to the instructions on the label, then rinse it off using the hose. When washing the coils it is essential not to use too much force as the fins can be bent easily.
After the coils have been cleaned, inspect them for any signs of damage. Over time hail and stones thrown by lawnmowers, and other items can damage the coil fins. If the fins are bent, an affordable tool called a fin comb can straighten them to improve air flow and aid in the operation of the coils more effectively.
When the fins and coils are in good shape, you can go back to your home and turn on your air conditioner. Check the thermostat every 24 hours to ensure the temperatures are in good shape.
Clean the Ductwork
Your HVAC system works by bringing air in from outside, cooling it, and distributing it throughout your home. The air is moved from the evaporator coil inside your condenser unit to your house’s vents and registers through a system of ducts. If these ducts aren’t properly cleaned and sealed, they may be laden with dust and other contaminants. This can block the air filters and reduces the efficiency of the system and puts strain on your AC unit.
In the majority of cases, cleaning the ductwork isn’t an easy task that requires the help of professional equipment and techniques. There are some actions you can take regularly to keep your ducts tidy and in good working order. To prevent dust and allergens from building up in the ducts, it is recommended to change your filter regularly. This will also help to prevent the clogging that can lead to reduced system efficiency and higher energy costs.
Cleaning the area around the vent openings is a different way to keep your ducts cleaner. By using the hose attachment on your vacuum cleaner can remove all the dust and crumbs that build up over time, and assist in improving airflow through the vent. You should also make sure that your ducts are sealed tight and protected from moisture getting in, which could lead to mold and other biological contaminants.
Ducts that have not been cleaned on a regular basis are likely to be contaminated with a myriad of contaminants, including dust, pet dander and pollen. These particles can exacerbate respiratory and allergies, especially for older people and children. Moisture can also cause mold to develop in ductwork, which releases the spores that can be harmful to those suffering from respiratory ailments.
It is recommended that you clean your ducts once every three to five years to remove these contaminants and ensure that your HVAC system is functioning efficiently. However If your ducts are sealed properly and you regularly change your filters it is possible that duct cleaning won’t be required at all. The best way to determine for sure is by having your ducts tested. A certified contractor can employ specific testing methods to determine the amount of dust particles in your ductwork, and can recommend appropriate cleaning schedules that are based on your specific situation.
Check the Compressor
The compressor is a critical element of the system. It should be able deliver cool air into the ducts. If the compressor isn’t working as it should, this can affect your productivity and cause interruption to your equipment. Preventive maintenance can help spot minor issues early, preventing excessive downtime. Conducting these regular checks can also save you money by ensuring that your equipment is in good condition for as long as it is possible.
The most common indication of a problem with a compressor is a reduction in cooling capacity, however this could be caused by many different causes. A compressor may be working too hard due to poor airflow. This can cause the bearings to wear out and decrease the life of the compressor. A clogged air filter is a different issue. If the filter is clogged, it can reduce the airflow to the compressor, which can cause overheating. To prevent this, it is essential to clean or change the filters regularly based on the manufacturer’s recommendations.
A clogged filter may also cause a rattling sound in the compressor. This can indicate that the bearings are wearing out and must be replaced. Regularly replacing belts and pulleys is a good idea. 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 on a regular basis. This will get rid of the moisture that could cause corrosion to the motor and other components. A professional service team will look for leaks in the hoses, as well as a tight seal on the pressure sensor and compressor.
A puddle of liquid near the compressor could be a sign of an issue. This is a serious issue that needs to be addressed immediately. If you suspect a leak, turn off the air compressor. Consult a professional.
Check the Thermostat
The thermostat acts like the head of your entire HVAC system, and it’s no surprise 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 among the most frequently neglected maintenance items. Common indicators that your thermostat is in need of an inspection include inaccurate temperature readings, ineffective controls, or continuous cycling.
Inaccurate Temperature Readings
Thermostat sensors may become dirty over time, which can cause the thermostat to display inaccurately. You can prevent these issues by checking the accuracy of your thermostat with a separate thermometer.
A faulty sensor or calibration could cause your system to keep turning on and off, which is referred to as short cycling. This can affect your comfort, and cause excessive wear and tear on the compressor. Fortunately the majority of these issues can be fixed with simply replacing the batteries in your thermostat or resetting the breaker.
Make sure you check the breakers on both your thermostat and HVAC equipment if your system doesn’t respond to your thermostat. If the breaker has tripped, it will have to be reset in order for the thermostat to connect with the system.
It’s also crucial to examine your thermostat for any signs of wear or damage. Look for dust or dirt and ensure that the thermostat is not excessively exposed to the sun. Finally, the fan blades need to be examined for signs of damage or rust. These simple checks can help avoid costly repairs in the future, and help ensure that your equipment is running as smoothly as possible.
The simple maintenance of hvac systems on your commercial property is an excellent method to cut the cost of energy, maintain comfort and extend the longevity of your cooling and heating equipment. You can ensure that your building stays cool throughout the year by identifying any issues with your thermostat, then resetting your breaker and replacing your batteries. Just remember that in case you experience any other issues or are unsure about the issue make sure to contact a professional.
