The Importance of HVAC Maintenance
Maintenance is key when it comes to heating and cooling systems. It will allow you to avoid costly repairs or premature replacement. Most HVAC companies offer a maintenance plan that charges a low monthly rate to have the system checked, fixed or cleaned as required.
It’s also recommended to do some of the 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 your air conditioner condenser are the primary component of the cooling process. If they are dirty, your system will be unable to cool properly and may even fail to function properly. Cleaning them is a crucial component of HVAC maintenance. Fortunately, it is also quite simple to do. This easy DIY task will save you money, avoid costly repairs and prolong the life span of your air conditioner.
In the beginning, it is important to disconnect the power to your unit. This can be done by shutting off the breaker in your electrical box or by turning off the outdoor unit disconnect switch. This will stop your motors and other electrical components from being oversaturated during cleaning.
Once the power is off, you can begin clearing any large objects that could be hindering the condenser’s air. This includes cleaning off any sticks, leaves, or other debris that has built up around or on the unit. A shop vacuum that has crevice tools is a great way to get into the nooks, crannies and remove dirt or dust that has accumulated.
The coils require to be cleaned. Before doing this however, ensure you have a few key tools. Included in this are a coil cleaning concentrate, a pump up garden sprayer as well as the garden hose. Spray the coil cleaner in accordance with the instructions on the label, then rinse with the garden hose. When washing the coils it is important not to apply too much force since the fins are easily bent.
After the coils have been cleaned, examine them for indications of damage. Over time hail, rocks thrown by lawnmowers and other things can harm the coil’s fins. If the fins are bent, a cost-effective tool known as a fin-comb can straighten them for better air flow and to help the coils function more effectively.
After you have a proper coil and fin set up and you are ready to switch on your air conditioner. Check the thermostat every 24 hours to ensure 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 the home. The air is transported from the evaporator inside the condenser to your home’s registers and vents through a system ducts. If these ducts aren’t cleaned and sealed, they could be laden with dust and other pollutants. This could block air filters, which decreases the efficiency of your system and strains your AC unit.
In most instances, cleaning ductwork isn’t an easy task and requires the help of professional equipment and methods. However, there are a few actions you can take on a regular basis to make sure your ducts remain in good condition and function properly. First, you should change your filter on a regular basis to keep dust and allergens from building into the ducts. This can also help stop the clogging that could lead to reduced system efficiency and a high energy bill.
Another way to help keep your ducts clean is to regularly cleaning the area around the vent openings. The hose attachment of your vacuum cleaner will get rid of all the crumbs, cobwebs and other messes that have built up over time. This will increase airflow through the vent. You should also make sure that your ducts are sealed well and are insulated to prevent moisture from getting in, which could result in mold and other biological contaminants.
If ducts are not cleaned regularly, they could accumulate a variety of contaminants like dust, pet dander, and pollen. These particles can worsen respiratory and allergy conditions, particularly in children and the elderly. The moisture in ductwork can result in the growth of mold which releases spores into air and poses health risks for those who suffer from respiratory problems.
It’s generally recommended that you have your ducts cleaned every three to five years in order to eliminate these contaminants and ensure your HVAC system is operating efficiently. However it is possible that if your ducts are sealed and you regularly change your filters, duct cleaning may not be required at all. The best way to determine for sure is by having your ducts tested. An accredited contractor can use specific testing methods to determine the amount of dust particles in your ductwork and can recommend appropriate cleaning schedules that are based on your particular situation.
Check the Compressor
The compressor is an essential element of the system. It must function correctly to supply cool air to the ducts. If the compressor isn’t operating properly, it could affect your productivity and result in interruption to your equipment. Preventive maintenance can help identify minor issues earlier, avoiding excessive downtime. Regularly checking your unit can also help you save money by ensuring that your equipment is in good working order for as long as it is possible.
The most common sign of a compressor issue is a reduction in cooling capacity, however this could be due to various factors. A compressor could be working too hard due to inadequate airflow. This can cause the bearings to wear out and decrease the life of the compressor. A blocked air filter is another frequent problem. Filters that have become blocked can restrict airflow and cause the compressor to overheat. It is essential to clean or replace the filters in accordance with the manufacturer’s guidelines.
Additionally, a blocked filter may create a rattling sound inside the compressor. This could be a sign that the bearings must be changed. It is recommended to replace pulleys and belts on a regular basis. A loose belt or pulley can cause the compressor to overheat and create other issues. It’s also a good idea to drain your compressor regularly. This will help remove moisture that could cause corrosion to the motor and other components. A professional service team will also look for leaks in the pipes, and ensure a tight seal on the compressor and pressure sensor.
A puddle of liquid in the vicinity of the compressor could be an indication of leak. This can be a dangerous issue and should be repaired immediately. If you suspect there is a leak, switch off the compressor that is running and then contact a professional.
Check the Thermostat
It’s not too surprising that a technician will always examine the thermostat first if there’s an issue. A well-maintained thermostat is crucial to the proper operation of your HVAC system. It’s one of the most overlooked maintenance items. Common signs that your thermostat requires a check-up include incorrect temperature readings, ineffective controls, or continuous cycling.
Inaccurate Temperature Readings
Over time the thermostat’s sensors may become dirty. This can cause it to display incorrectly. Monitoring your thermostat’s accuracy regularly by using a separate thermometer can help you avoid these problems and help you save energy.
A malfunctioning sensor, or a wrong calibration, could cause your system to turn off and on constantly. This is known as short cycling. This could have a negative effect on your comfort and result in excessive wear and tear on the compressor. Fortunately this can be resolved with simply replacing the batteries in your 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 and your HVAC equipment. If the breaker has tripped, it will need to be reset to allow the thermostat to be able to communicate with the system again.
Check your thermostat for indications of wear and tear. Check for signs of dirt or dust, and make sure the thermostat isn’t too exposed to sunlight. Examine the fan blades to find signs of damage and rust. These simple checks can help avoid costly repairs in the near future, and ensure your equipment is operating as smoothly as it is possible.
Basic hvac maintenance is a great way to reduce energy costs and ensure comfort in your commercial building. It will also extend the lifespan of cooling and heating equipment. It is possible to keep your building comfortable throughout the year by identifying issues with your thermostat, resetting your breaker and replacing your batteries. Be sure to call an expert if you’re experiencing any other issues or aren’t sure what’s wrong with your system.
