The Importance of HVAC Maintenance
Maintenance is essential when it concerns heating and cooling systems. It will allow you to avoid costly repairs or premature replacement. The majority of HVAC companies offer a service plan where you pay an annual fee to have the system checked and cleaned or repaired when required.
It’s also an excellent idea to carry out a few DIY maintenance tasks throughout the year. These include cleaning or replacing air filters, and keeping the area around outdoor units free of clutter to allow for the proper flow of air.
Clean the Condenser
The coils in the condenser of your air conditioner are the heart of the cooling process. If they’re dirty your 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 accomplish. This easy DIY task will save you money, avoid expensive repairs and extend the life of your air conditioner.
It is the first step. It is essential to cut off the power to your unit. This can be done by turning off the breaker inside the electrical box, or by turning off the outdoor unit disconnect switch. This will prevent your motors and other electrical components from being oversaturated while cleaning.
After the power is off, you can start taking down any large debris that could be blocking the condenser’s air. This includes sweeping up any sticks, leaves, or other debris that has built up around or on the unit. A shop vacuum equipped with a crevice tool is an excellent way to get into the nooks and crannies, and loosen dust or dirt that has accumulated.
Next, it is time to clean the coils. Be sure to have a few essential tools available prior to beginning. This will include a coil cleaner concentrate, a pump-up garden sprayer and a garden hose. Spray the coil cleaner in accordance with the instructions on the label, then rinse it off using a garden hose. When washing the coils it is important not to apply too much force as the fins are easily bent.
You should examine 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. Fin combs can be used to straighten bent fins for improved airflow and coil performance.
Once the coils and fins are in good shape Once you’re satisfied with the condition of the fins and coils, you can go back to your home and start your air conditioner. Check the thermostat every 24 hours to confirm that temperatures are normal.
Clean the Ductwork
Your HVAC system works by bringing air in from outside, cooling it, and distributing it throughout your home. Air is moved from the evaporator inside your condenser to your home’s registers and vents through the system ducts. If the ducts aren’t cleaned and sealed, they could be laden with dirt and other contaminates. This can clog the air filters, which decreases the effectiveness of your system as well as can strain your AC unit.
In most instances, cleaning ductwork isn’t an easy job and requires the help of professional equipment and techniques. However, there are some actions you can take regularly to make sure your ducts remain clean and well-functioning. To prevent dust and allergens from accumulating in the ducts, it is recommended to change your filter regularly. This will also help to keep the clogs from occurring which can lead to reduced system efficiency and high energy bills.
Vacuuming the area surrounding the vent openings is another way to keep your ducts cleaner. The hose attachment of your vacuum cleaner will remove all the crumbs, cobwebs and other debris that has built up over time. This will increase airflow through the vent. It’s also important to make sure your ducts are properly sealed and insulated to keep out moisture, which can cause mold and other biological contaminants.
Ducts that are not regularly cleaned can be filled with a variety of contaminants, including dust, pet dander and pollen. These particles can worsen allergies and respiratory issues especially in the elderly and children. The moisture can cause mold to grow in ductwork, which releases spores that are harmful to people suffering from respiratory issues.
It is recommended to clean your ductwork every three to five years to remove these contaminants and ensure that your HVAC system is functioning efficiently. If your ducts have been well-sealed, and you regularly change your filter It may not be necessary to clean them. You can only be certain that your ducts are in good condition by having them checked. A certified contractor can employ special testing methods to gauge the amount of dust particles within your ductwork, and will suggest appropriate cleaning schedules based on your particular situation.
Check the Compressor
The compressor is an essential component of the system. It has to be able to provide cool air to the ducts. If the compressor isn’t operating as it should, this can affect the efficiency of your business and lead to delays for your equipment. Preventive maintenance can help identify small issues early, preventing unnecessary downtime. Performing these routine checks can also help you save money by keeping your unit in good condition for as long as is possible.
A typical sign of a compressor issue is a reduction in cooling capacity, but this could be caused by various factors. A compressor could be working too hard due to inadequate airflow. This can cause bearings to wear out and decrease the life of the compressor. A blocked air filter is another common problem. If the filter is blocked it could reduce the airflow to the compressor and cause overheating. To avoid this, it is essential to clean or change the filters frequently, according to the manufacturer’s recommendation.
A blocked filter can cause a rattling sound in the compressor. This could be a sign that the bearings need to be replaced. It is also a good idea to replace pulleys and belts on a regular basis. A worn-out belt or pulley can cause the compressor to overheat and create other issues. It is also a good idea to drain the compressor on a regular basis. This will remove moisture that can cause corrosion to the motor and other parts. A professional service team can examine for air leaks within the hoses, and ensure a tight seal between the compressor and the pressure switch.
A pool of water in the vicinity of the compressor can be an indication of a leak in the refrigerant. This is a risky problem that should be addressed immediately. If you suspect there is a leak, switch off the air compressor and call a professional.
Check the Thermostat
The thermostat is like the head of your HVAC system, and it’s not a surprise that it’s the first thing a technician will look at when trouble arises. It’s also one of the most often neglected maintenance items, yet a properly maintained thermostat is crucial for ensuring your HVAC system’s proper operation. The most common signs that your thermostat is in need of an inspection include inaccurate temperature readings, non-responsive controls, or constant cycling.
Inaccurate Temperature Readings
Over time the sensors on your thermostat can become dirty. This could cause it to display in a wrong manner. Regularly checking your thermostat’s accuracy with a separate thermometer will help you avoid these problems and save energy.
A defective sensor or a flawed calibration could cause your system to turn off and on constantly. This is referred to as short cycling. This can adversely affect your comfort and cause excessive wear and tear on the compressor. The problem can be fixed by replacing the thermostat’s batteries or resetting the breaker.
If your system isn’t responding to your thermostat at all it’s recommended to examine the breakers that control the thermostat as well as your HVAC equipment. If the breaker has been tripped, it will require resetting to allow the thermostat to connect with the system.
It is also essential to examine your thermostat for signs of wear or damage. Look for dust or dirt and ensure that the thermostat isn’t excessively exposed to the sun. Examine the fan blades to find signs of damage and rust. This simple check will help avoid costly repairs in the future and ensure that your equipment is running as smoothly as it can.
Basic HVAC maintenance is a great way to save energy and maintain comfort in your commercial space. It can also prolong the lifespan of heating and cooling equipment. By identifying problems with your thermostat, resetting the breaker, and replacing the batteries and fuses, you’ll be able keep your building cool all year round. Remember to call a professional if you are having any other problems or aren’t sure what’s wrong with your system.
