The Importance of HVAC Maintenance
Maintenance is key when it comes to HVAC and cooling systems. It can help you avoid costly repairs or premature replacement. Most HVAC companies offer a service plan where you pay a low monthly rate to have the system checked out, fixed or cleaned as required.
You should also perform some DIY maintenance throughout the year. Cleaning or replacing air filters and keeping the area surrounding outdoor units clear of debris will promote the proper flow of air.
Clean the Condenser
The coils that make up your air conditioner’s condenser are the mainstay of the cooling process. If they’re dirty, your system will struggle to cool and may even breakdown. Cleaning them is an important aspect of HVAC maintenance. It’s fairly easy to do. This easy DIY task will save you money, avoid expensive repairs and extend the life span of your air conditioner.
It is the first step. It is essential to cut off the power source to your unit. This can be accomplished by shutting off the breaker inside the electrical box, or by turning off the outdoor unit disconnect switch. This will safeguard your electrical components and motors from being over-saturated when cleaning.
After the power is off, you can begin clearing any large debris that could be hindering the condenser air. This includes sweeping away any sticks, leaves, or other debris that have built up on or around the unit. Utilizing a shop vacuum that has crevice attachments is a great way to get into the nooks and crevices and loosen any dirt, dust or other debris that has accumulated.
The next step is to clean the coils. Make sure you have some essential tools available before you begin. This will include a concentrate for coil cleaning and a pump-up garden hose and a garden hose. Spray the coil cleaner in accordance with the instructions on the label, and then rinse it off with the water hose. When washing the coils it is essential not to use too much force as the fins can be bent easily.
You should examine the coils for signs of damage following cleaning. Over time, hail and rocks that are thrown by lawnmowers and other objects can cause damage to coil fins. If the fins are bent, a low-cost tool known as a fin comb can straighten them to improve air flow and also to help the coils function more efficiently.
If the fins and coils are in good condition, you can return to your home and turn on your air conditioner. Make sure to check the thermostat after 24 hours to make sure the temperatures are in good shape.
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 your condenser unit to your house’s vents and registers through a system of ducts. If the ducts aren’t cleaned and sealed, they may become clogged with dust and other contaminants. This could block air filters which can reduce the effectiveness of your system and can strain your AC unit.
In the majority of cases, cleaning the ductwork is not an easy task and requires expert equipment and techniques. However, there are a few actions you can take regularly to ensure that your ducts are clean and well-functioning. To avoid dust and allergens accumulating in the ducts, you should change your filter on a regular basis. This will also help to prevent clogging, which can cause a decrease in efficiency and higher energy costs.
Vacuuming the area around the vent openings is another way to keep your ducts in good shape. The hose attachment of your vacuum cleaner will take away all traces of dust, crumbs and other debris that has been accumulating over time. This will increase the flow of air through the vent. It is also important to make sure your ducts are sealed and sealed with insulation to keep out moisture, which can lead to mold and other biological contaminants.
If ducts aren’t cleaned regularly, they could collect a variety of pollutants such as dust, pet dander, and pollen. These particles can exacerbate respiratory issues and allergies particularly in children and the elderly. In addition, moisture in ductwork may result in the growth of mold, which releases spores into air and can cause health issues for those with respiratory ailments.
It is recommended that you clean your ducts every three to five years to get rid of these toxins and ensure that your HVAC system is functioning efficiently. If your ducts have been well-sealed, and you change your filter regularly It may not be necessary to clean them. The best way to know for sure is by having your ducts examined. A certified contractor can employ specific testing methods to determine the amount of particles in your ductwork and can recommend suitable cleaning schedules based upon your specific situation.
Check the Compressor
The compressor is an essential element of the system. It must function properly to deliver cool air to the ducts. If the compressor isn’t working in the way it should, this can impact your productivity and result in delays for your equipment. However, preventive maintenance can assist in identifying issues that are minor and help avoid prolonged downtime. Regular checks can also save you money by making sure that your equipment as efficient as possible.
A loss of cooling capacity is a common sign of a problem with a compressor. This could be caused by a variety of reasons. A compressor may be operating too hard due to inadequate airflow. This could wear out the bearings and reduce the lifespan of the compressor. A blocked air filter is another frequent problem. If the filter is clogged it can impede airflow to the compressor, which can cause overheating. It is essential to change or clean the filters according to manufacturer’s instructions.
Additionally, a blocked filter could create a rattling sound inside the compressor. This could indicate that the bearings are worn out and need to be replaced. Regularly replacing the belts and pulleys is an excellent idea. A loose belt or pulley can slip, causing the compressor to overheat and cause other problems. It is recommended to drain the compressor regularly. This will help remove moisture that can corrode the motor and other components. A professional service team will examine for leaks in pipes, and ensure a tight seal on the pressure sensor and compressor.
Lastly, a pool of water in the vicinity of the compressor could be an indication of a leak in the refrigerant. This is a serious problem and needs to be fixed right away. If you suspect that there is a leak, turn off the air compressor. Get a professional to assist you.
Check the Thermostat
The thermostat is kind of like the head of your entire HVAC system, and it’s not a surprise that it’s the first thing a technician will inspect when a problem arises. It’s also one of the most commonly overlooked maintenance items, yet an appropriately maintained thermostat is essential to ensure your HVAC system’s operation. Check your thermostat if notice incorrect temperature readings, unresponsive controls, or constant cycling.
Inaccurate Temperature Readings
Over time, the sensors on your thermostat may become dirty. This could cause it to display in a wrong manner. You can avoid this issue by regularly checking the accuracy of your thermostat using a a separate thermometer.
A malfunctioning sensor, or a flawed calibration could cause your system to cycle on and off continuously. This is called short cycling. This can have a negative impact on your comfort and result in excessive wear and tear on the compressor. The problem can be fixed by simply replacing the batteries in the thermostat or resetting the breaker.
Make sure you check the breakers on both your HVAC equipment and thermostat if your system doesn’t respond to your thermostat. If the breaker has tripped, it’ll require resetting to allow the thermostat to connect with the system again.
It’s also crucial to examine your thermostat for any signs of wear or damage. Check for dirt or dust and ensure that the thermostat is not too much exposed to sunlight. Examine the fan blades for signs of damage and rust. These simple checks will prevent costly repairs in the future and will ensure that your equipment operates as smoothly as it can.
Basic maintenance of hvac is a great way to reduce energy costs and keep your comfort in a commercial property. It also increases the lifespan of cooling and heating equipment. It is possible to keep your building at all times comfortable by identifying problems with your thermostat, setting your breaker and changing your batteries. Remember to call an expert if you’re having other issues or are unsure of what’s going on with your system.
