The Importance of HVAC Maintenance
Maintenance is crucial when it is concerned with cooling and heating systems. It will help you avoid costly repairs or premature replacement. Most HVAC companies offer a service plan that you pay a low monthly rate to have the system checked, repaired or cleaned if needed.
It is also recommended to perform DIY maintenance throughout the year. This includes cleaning or replacing air filters, and keeping the area around outdoor units free of any debris to ensure the proper airflow.
Clean the Condenser
The coils inside your air conditioner’s condenser are the core of the cooling process. If they’re dirty, your system will struggle to cool, and it could even fail. Cleaning them is an essential aspect of HVAC maintenance. It is, fortunately, fairly easy to do. This simple DIY task will save you money, avoid expensive repairs and extend the lifespan of your air cooling.
It is essential to disconnect power from your unit first. This can be done by turning off the breaker in 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.
After the power has been turned off, you can begin taking down any large objects that could be blocking the condenser air. This means sweeping away any sticks, leaves, or other debris that has accumulated on or around the unit. Utilizing a shop vacuum that has a crevice attachment is a great method to get into the nooks and crevices and remove dust, dirt or other debris that has accumulated.
The coils need to be cleaned. Be sure to have a few essential tools on hand prior to beginning. This will include a coil cleaner concentrate and a pump-up garden sprayer and a garden hose. Spray the coil cleaner according to the directions on the product label and then rinse it off using the hose. It is important not to use too much pressure when washing the coils, since the fins could easily be bent.
After the coils have been cleaned, inspect them for any indications of damage. Over time hail and stones thrown by lawnmowers, and other objects can cause damage to the coil fins. If the fins are bent, an affordable tool known as a fin comb can straighten them for better air flow and to help the coils function more effectively.
If the fins and coils are in good shape Once you’re satisfied with the condition of the fins and coils, you can return to your home and switch on your air conditioner. Check the thermostat after about 24 hours to confirm that the temperatures are in good shape.
Clean the Ductwork
Your HVAC system is able to bring air from outside, cooling it, and distributing it throughout your home. The air moves from the evaporator coil of the condenser unit to the vents and registers of your home through a network of ducts. The ducts could become blocked with dust and other pollutants if they are not cleaned and sealed properly. This could block air filters which can reduce the effectiveness of your system as well as can strain your AC unit.
Cleaning the ductwork can be a difficult task that requires specialized equipment and techniques. There are a few things you can do regularly to keep your ducts clean and working well. First, make sure you change your filter on a regular basis to keep dust and allergens from accumulating into the ducts. This will also help prevent clogging, which can result in a decrease in system efficiency and higher energy costs.
Another way to help keep your ducts tidy is to regularly vacuuming the area around the vent openings. By using the hose attachment on your vacuum cleaner, you can get rid of all cobwebs and crumbs which accumulate over time, and will assist in improving air flow through the vent. It is also essential to ensure that your ducts are tightly sealed and insulated to keep out moisture which can lead to mold and other biological contaminants.
If ducts aren’t regularly cleaned, they may build up a myriad of contaminants like dust, pet dander and pollen. These particles can worsen allergies and respiratory issues, particularly in children and the elderly. The moisture can cause mold to grow in the ductwork, which releases spores that are harmful to people suffering from respiratory issues.
It’s generally recommended that you have your ducts cleaned every three to five years to remove these contaminants and ensure your HVAC system is working effectively. If your ducts have been sealed well and you change your filter regularly, it may not be necessary to clean them. The best way to be able to tell for certain is to have your ducts examined. A licensed contractor can employ specific testing methods to determine the amount of particles within your ductwork, and will suggest suitable cleaning schedules based upon your particular situation.
Check the Compressor
The compressor is an essential element of the system. It must be able to supply cool air into the ducts. If the compressor isn’t operating in the way it should, this can impact your productivity and result in delays for your equipment. Fortunately, preventive maintenance can help catch minor issues early and prevent unnecessary downtime. Performing these routine checks can also save you money by ensuring that your equipment is in good condition for as long as it is possible.
A common sign of a compressor problem is a reduction in cooling capacity, although this could be due to various factors. A compressor may be working too hard due insufficient airflow. This can cause wear on the bearings and decrease the life of the compressor. Another issue that is common is a blocked filter. Filters that are blocked can reduce airflow and cause the compressor to overheat. To prevent this from happening, it is important to clean or replace the filters on a regular basis, based on the manufacturer’s recommendation.
A clogged filter may also cause a rattling sound in the compressor. This can indicate that the bearings are worn out and must be replaced. Regularly replacing the belts and pulleys is an excellent idea. A loose pulley or belt could cause slipping and result in compressor overheating and other issues. It is recommended to drain the compressor regularly. This will remove the accumulated moisture that can cause corrosion to the motor and other components. A professional service team can also check for air leaks in the hoses, and ensure a tight seal between the compressor and pressure switch.
A puddle of liquid in the vicinity of the compressor could be an indicator of a leak. This is a risky problem that should be addressed immediately. If you suspect a leak, shut off the air compressor. Consult a professional.
Check the Thermostat
The thermostat is like the head of your entire HVAC system, so it’s not a surprise that it’s the first thing that a technician will check when trouble occurs. It’s also among the most commonly overlooked maintenance items, but an appropriately maintained thermostat is crucial for ensuring your HVAC system’s proper operation. Check your thermostat if you notice incorrect temperature readings, unresponsive controls or constant cycling.
Inaccurate Temperature Readings
Over time the thermostat’s sensors may become dirty. This could cause it to display in a wrong manner. Monitoring your thermostat’s accuracy regularly by using a separate thermometer can aid in avoiding these issues and help you save energy.
A faulty sensor or calibration may lead to your system continuously switching on and off this is known as short cycling. This could have a negative effect on your comfort and result in unnecessary wear and tears on the compressor. This issue can be solved by simply replacing the batteries in the thermostat or resetting the breaker.
If your system isn’t responding to your thermostat in any way, it’s recommended to examine the breakers that control the thermostat as well as your HVAC equipment. If the breaker has tripped it, you’ll 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. Look for evidence of dust or dirt and ensure that the thermostat isn’t exposed to sunlight. Lastly, the fan blades must be inspected for any indications of rust or damage. This simple check will help avoid costly repairs in the future, and ensure that your equipment is running as smoothly as it possibly can.
The simple maintenance of hvac systems on your commercial property is a great way to reduce the cost of energy, maintain comfort, and extend the lifespan of your cooling and heating equipment. By identifying issues with your thermostat, setting the breaker and replacing the batteries, you’ll be able to keep your building warm all year round. Make sure to contact a professional if you are having any other problems or unsure of what is the issue with your system.
