The Importance of HVAC Maintenance
Maintenance is essential when it comes to HVAC and cooling systems. It will allow you to avoid costly repairs or premature replacement. Most HVAC companies have a service plan that allows you to pay a monthly fee to have the system checked, repaired or cleaned as needed.
You should also carry out some DIY maintenance throughout the year. This includes cleaning or replacing air filters, and keeping the space around outdoor units free of clutter to allow for the proper flow of air.
Clean the Condenser
The coils inside the condenser of your air conditioner are the heart of the cooling process. If they are dirty the system is likely to struggle to cool and could even fail. This is why cleaning them is an essential aspect of HVAC maintenance. It’s also quite simple to do. This simple DIY task will eliminate the need for costly repairs, and save you money on your energy bills, and extend the longevity of your AC unit.
It is the first step. It is crucial to shut off the power source to your unit. You can do this by turning off the breaker at your electrical box or the outdoor unit disconnect switch. This will protect your electrical components and motors from being oversaturated when cleaning.
After the power has been shut off it is now time to clear any large debris that is obstructing the air condenser unit. This means sweeping up any sticks, leaves or other debris that have accumulated on or around the unit. Using a shop vacuum with crevice attachments is a great way to get into the crevices and nooks and get rid of any dust, dirt or other debris that may have accumulated.
The next step is to clean the coils. Before you do this however, ensure that you have on-hand some essential tools. This will include a concentrate for coil cleaning, a pump-up garden sprayer and a garden hose. Spray the coil cleaner on in accordance with the directions on the product’s label and then rinse using the hose. It is crucial not to apply excessive pressure when washing the coils since the fins could easily be bent.
After the coils have been cleaned, you should inspect them for any indications of damage. Over time hail, stones thrown by lawnmowers, and other items can damage the coil fins. If the fins are bent, a cost-effective tool called a fin comb can straighten them to improve air flow and also to help the coils function more efficiently.
Once you have a good coil and fin setup then you can start your air conditioner. Make sure to check the thermostat after 24 hours to confirm that the temperatures are in good shape.
Cleaning the Ductwork
Your HVAC system works by bringing air from outside, cooling it, and distributing it throughout the home. The air is moved from the evaporator coil in the condenser unit to your home’s vents and registers through a network of ducts. If these ducts aren’t cleaned and sealed, they can become clogged with dust and other contaminants. This could block air filters, which decreases the effectiveness of your system and can strain your AC unit.
In the majority of cases, cleaning the ductwork isn’t an easy job and requires the help of professional equipment and methods. However, there are some actions you can take regularly to ensure your ducts are clean and functioning well. First, you should change your filter on a regular basis to keep dust and allergens from accumulating up in the ducts. This also helps to keep the clogs from occurring which can result in a lower efficiency of the system and a high energy bill.
Another method to keep your ducts clean is by regularly cleaning the area around vent openings. The hose attachment on your vacuum cleaner will remove all traces of dust, crumbs and other messes that have accumulated over time. This will improve airflow through the vent. It is also important to ensure that your ducts are sealed tight and insulated to prevent moisture from getting in, which could lead to mold and other biological contaminants.
Ducts that are not cleaned on a regular basis can be filled with a myriad of contaminants, such as dust, pet dander, and pollen. These particles can trigger respiratory issues and allergies particularly in children and the elderly. In addition, moisture in ductwork may lead to the growth of mold, which releases spores in the air and poses health concerns for those who suffer from respiratory issues.
It is recommended to clean your ductwork every three to five year to remove these contaminants and ensure that your HVAC works efficiently. However, if your ducts are well-sealed and you regularly change your filters the cleaning of your ducts may not be necessary at all. The best way to determine the truth is to have your ducts tested. A contractor who is accredited by the EPA can use special testing techniques to determine the amount of particulates found in your ductwork. They can then recommend cleaning schedules that are appropriate for your particular situation.
Check the Compressor
The compressor is an essential element of the system. It should be able provide cool air to the ducts. If the compressor isn’t working properly, it can affect your productivity and result in delays for your equipment. Fortunately, preventive maintenance can aid in identifying minor issues early and avoid excessive downtime. These regular checks will also save you money by making sure that your unit as good as possible.
A loss of cooling capacity is a typical sign of a problem in a compressor. This can be caused by several different causes. One possibility is that a compressor may be working too hard due to poor airflow. This could wear out the bearings and diminish the lifespan of the compressor. Another common issue is a clogged filter. If the filter is clogged it can impede airflow to the compressor and lead to overheating. It is essential to clean or replace the filters according to manufacturer’s instructions.
A clogged filter may also cause rattling sounds in the compressor. This could indicate that the bearings are wearing out and require to be replaced. Regularly replacing belts and pulleys is recommended. A worn belt or pulley can slip and lead to overheating of the compressor and other issues. It is 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 can also examine for air leaks within the hoses, and ensure a tight seal between the compressor and pressure switch.
Finally, a puddle of water near the compressor can be an indication of a refrigerant leak. This is a potentially dangerous problem that must be dealt with immediately. If you suspect there is a leak, shut off the air compressor and contact a professional.
Check the Thermostat
It’s not surprising that a technician will examine the thermostat first if there is an issue. It’s also one of the most often neglected maintenance items, but maintaining your thermostat properly is essential to ensure your HVAC system’s optimal operation. Common indicators that your thermostat needs an inspection include inaccurate temperature readings, unresponsive controls, or constant cycling.
Inaccurate Temperature Readings
Over time, the sensors on your thermostat can become dirty. This can cause it to display inaccurately. You can prevent these issues by checking the accuracy of your thermostat with the use of a separate thermometer.
A malfunctioning sensor or calibration could result in your system constantly turning on and off, which is referred to as short cycling. This could have a negative effect on 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 its breakers.
Make sure you check the breakers on both your HVAC equipment and thermostat in the event that your HVAC equipment doesn’t respond to your thermostat. If the breaker has tripped, it’ll have to be reset in order for the thermostat to be able to communicate with the system once more.
It’s also important to check your thermostat for signs of wear or damage. Examine for dust or dirt and ensure that the thermostat is not overly exposed to the sun. Lastly, the fan blades need to be examined for indications of rust or damage. These simple checks will help prevent costly repairs in the near future, and help ensure that your equipment is running as smoothly as it is possible.
Basic HVAC maintenance is a great method to cut down on energy costs and maintain comfort in your commercial building. It will also extend the life of heating and cooling equipment. By identifying any issues with your thermostat, resetting the breaker, and replacing the batteries and fuses, you’ll be able keep your building warm all year. Remember to call a professional if you are experiencing any other issues or are unsure of what’s the issue with your system.
