The Importance of HVAC Maintenance
Maintenance is essential when it is concerned with heating and cooling systems. It can help you avoid costly repairs or premature replacement. Most HVAC companies offer a maintenance plan that you pay an affordable monthly fee to have your system checked out, fixed or cleaned as needed.
It’s also recommended to do some of the 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 that make up your air conditioner’s condenser are the core of the cooling process. If they are dirty, your system will struggle to cool and could even breakdown. This is why cleaning them is a crucial component of HVAC maintenance. It is, fortunately, quite simple to do. This simple DIY task will save you money, prevent costly repairs and prolong the lifespan of your air conditioner.
In the beginning, it is essential to cut off the power source to your unit. This can be done by shutting off the breaker at the electrical box, or the outdoor unit disconnect switch. This will stop your motors and other electrical components from being oversaturated while cleaning.
After the power has been shut off, you can begin to remove any large debris that is blocking the air condenser unit. This includes cleaning off any sticks, leaves, or other debris that have accumulated on or around the unit. A shop vacuum that has crevice tools is an excellent way to get into the nooks and crannies, and loosen dirt or dust that has been accumulating.
Next, it is time to clean the coils. Before you begin, though, make sure that you have on-hand several essential tools. Included in this are coil cleaning concentrates and a pump-up garden sprayer, and a garden hose. Spray the coil cleaner in accordance to the instructions on the label, and then rinse it off with the hose. It is important not to use too much pressure when washing the coils since the fins could easily be bent.
It is recommended to inspect the coils for signs of damage after cleaning. Over time hail or stones thrown by lawnmowers, and other items can damage the coil fins. Fin combs can be utilized to straighten bent fins for better airflow and coil performance.
After you have a proper coil and fin set up then you can start your air conditioner. Check the thermostat after about 24 hours to ensure temperatures are normal.
Cleaning the Ductwork
Your HVAC system works by bringing air from outside, cooling it and then 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 duct system. If these ducts aren’t properly cleaned and sealed, they could become loaded with dust and other pollutants. This can block the air filters, which in turn reduces the efficiency of your system and puts strain on your AC unit.
Cleaning the ductwork can be a challenging task that requires professional equipment and techniques. However, there are some actions you can take regularly to make sure your ducts are clean and well-functioning. First, you should change your filter regularly to prevent dust and allergens from accumulating into the ducts. This can also help keep clogs from occurring, which could lead to a reduced system efficiency and higher energy bills.
Vacuuming the area surrounding the vent openings is another method to keep your ducts cleaner. The hose attachment on your vacuum cleaner will get rid of all the crumbs, cobwebs and other debris that has been accumulating over time. This will improve airflow through the vent. It is also essential to make sure your ducts are sealed and insulated to keep out moisture which can lead to mold and other biological contaminants.
If ducts are not cleaned regularly, they can accumulate a variety of contaminants such as dust, pet dander and pollen. These particles can worsen allergies and respiratory problems especially in children and the elderly. The moisture can cause mold to grow in ductwork, which releases microbes that can harm those suffering from respiratory ailments.
It’s generally recommended that you get your ductwork cleaned every three to five years in order to eliminate the toxins and ensure that your HVAC system is working efficiently. However, if your ducts are well-sealed and you clean your filters frequently it is possible that duct cleaning won’t be necessary at all. You can be certain by having your ducts examined. A contractor that is certified by the EPA can use special testing methods in order to determine the amount of particulates found in your ductwork. They will then recommend cleaning schedules that are suitable for your specific 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 as it should and isn’t functioning properly, it could impact your productivity and cause equipment downtime. Preventive maintenance can help spot minor issues earlier, avoiding unnecessary downtime. Regular checks can also save you money by ensuring that your unit as good as possible.
A common sign of a compressor problem is a decrease in cooling capacity, but it could be caused by many different causes. A compressor could be working too hard due to inadequate airflow. This can cause wear on the bearings and reduce the lifespan of the compressor. A clogged air filter is another frequent problem. If the filter has become clogged it can impede airflow to the compressor and cause overheating. To avoid this, it is important to clean or change the filters on a regular basis, based on the manufacturer’s recommendation.
A blocked filter can cause rattling sounds in the compressor. This could be an indication that the bearings must be replaced. Regularly replacing pulleys and belts is a good idea. A loose pulley or belt could cause slipping and result in overheating of the compressor and other issues. It’s also a good idea to drain your compressor on a regular basis. This will get rid of the moisture that could cause corrosion to the motor and other parts. A professional service team can also look for air leaks in the hoses and an adequate seal between the compressor and pressure switch.
A puddle of liquid close to the compressor could be a sign of an issue. This can be a dangerous issue that needs to be addressed right away. If you suspect that there is a leak, shut off the air compressor. Contact a professional.
Check the Thermostat
It’s not a surprise that a technician will always check the thermostat first when there’s any issue. A well-maintained thermostat is essential for the proper operation of your HVAC system. It’s one of the most frequently neglected maintenance items. Common signs that your thermostat requires an inspection include inaccurate temperature readings, unresponsive controls, or continuous cycling.
Inaccurate Temperature Readings
Over time, the thermostat’s sensors can get dirty. This can cause it to display inaccurately. You can avoid these problems by regularly 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 that is known as short cycling. This can affect your comfort and result in unnecessary wear and tear to the compressor. Fortunately the majority of these issues can be resolved with the simple act of replacing the thermostat’s batteries or resetting the breakers.
If your system isn’t responding to your thermostat at all it’s recommended to examine the breakers that regulate the thermostat as well as your HVAC equipment. If the breaker has tripped, it will require resetting in order for the thermostat to communicate with the system once more.
It’s also crucial to examine your thermostat for any signs of wear or damage. Examine for dust or dirt and make sure that the thermostat isn’t too much exposed to sunlight. Examine the fan blades to find signs of damage and rust. These simple checks can help avoid expensive repairs in the future, and help ensure that your equipment is operating as efficiently as it is possible.
Basic HVAC maintenance is a great way to reduce energy costs and keep your comfort in a commercial building. It can also prolong the lifespan of heating and cooling equipment. It is possible to keep your building at all times comfortable by identifying problems with your thermostat, setting your breaker, and then replacing your batteries. Make sure that in case you experience any other issues or aren’t sure the issue you should always consult an expert.
