The Importance of HVAC Maintenance
When it concerns your cooling and heating system, maintenance is the key to avoiding costly repairs or early-than-necessary replacement. The majority of HVAC companies have a service plan where you pay a monthly fee to have your system checked, repaired or cleaned as required.
You should also perform 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 proper airflow.
Clean the Condenser
The coils in the condenser of your air conditioner are the core of the cooling process. If they’re dirty the system will struggle to cool properly and may even break down. Cleaning them is an important part of HVAC maintenance. It is relatively easy to accomplish. This easy DIY task will eliminate the need for expensive repairs, save you money on your energy bills, and prolong the lifespan of your air conditioning unit.
It is crucial to disconnect the power source from your unit first. This can be accomplished by turning off the breaker in the electrical box, or by turning off the outdoor unit disconnect switch. This will protect your electrical components and motors from being over-saturated when cleaning.
After the power has been shut off, you can start taking down any large debris that could be blocking the condenser air. This means taking away any sticks, leaves, or other debris that have built up on or around the unit. A shop vacuum with a crevice tool is a great tool to get into the nooks and crannies, and loosen dirt or dust that has been accumulating.
The next step is to clean the coils. Make sure you have a few essential tools available before you start. These will include a coil cleaner concentrate and a pump-up garden hose and a garden hose. Spray the coil cleaner on according to the directions on the product’s label and then rinse it off using the hose. It is essential not to apply too much pressure when washing the coils, because the fins may be bent.
After the coils have been cleaned, inspect them for any signs of damage. Over time, hail, stones thrown by lawnmowers, and other objects can cause damage to the coil’s fins. If the fins are bent, a low-cost tool known as a fin comb can straighten them to improve air flow and to help the coils function more efficiently.
When you have a great coil and fin set up, you can start your air conditioner. After approximately 24 hours, you should check the thermostat to ensure that the temperature is normal.
Clean the Ductwork
Your HVAC system is able to bring air from outside into your home, then cool it and then distribute it throughout your house. The air is transported from the evaporator inside your condenser to your home’s registers, vents, and registers by the system duct. These ducts may become clogged with dust and other pollutants when they aren’t maintained and sealed properly. This can block the air filters which can reduce the effectiveness of your system and burdens your AC unit.
Cleaning the ductwork is a challenging task that requires expert equipment and methods. But, there are things you can do on a regular basis to ensure your ducts stay clean and functioning well. To stop dust and allergens from accumulating in the ducts, change your filter regularly. This will also help to keep clogs from occurring, which could cause a decrease in efficiency and a higher cost for energy.
Vacuuming the area surrounding the vent openings is a different method to keep your ducts in good shape. The hose attachment of your vacuum cleaner will remove all the cobwebs, crumbs and other debris that have accumulated over time. This will increase the flow of air through the vent. It is also important to ensure that your ducts have been sealed tight and protected from moisture entering, which can lead to mold and other biological contaminants.
If ducts are not cleaned regularly, they could accumulate a variety of contaminants such as dust, pet dander and pollen. These particles can cause respiratory and allergy conditions especially in the elderly and children. In addition, moisture in ductwork may cause the growth of mold, which releases spores into the air and poses health concerns for those suffering from respiratory issues.
It is recommended to clean your ducts once every three to five year to remove these contaminants and ensure that your HVAC system is functioning efficiently. However, if your ducts are sealed and you clean your filters frequently the cleaning of your ducts may not be necessary at all. You can only be certain that your ducts are in good condition by having them checked. A certified contractor can employ special testing methods to measure the amount of particles within your ductwork, and will suggest suitable cleaning schedules based upon your specific situation.
Check the Compressor
The compressor is a critical component of the system. It has to function correctly to supply cool air to the ducts. If the compressor isn’t operating as it should it could affect your productivity and cause equipment downtime. Regular maintenance can help you identify minor issues early, preventing excessive downtime. Performing these routine checks can also help you save money by keeping your unit in good shape for as long as it is possible.
A typical indication of a problem with a compressor is a reduction in cooling capacity, but this could be due to many different causes. One possibility is that the compressor may be working too hard due to poor airflow. This could cause the bearings to wear out and reduce the lifespan of the compressor. Another common issue is a clogged filter. Filters that are blocked can reduce airflow and cause the compressor to overheat. It is essential to clean or change the filters in accordance with the manufacturer’s instructions.
A clogged filter may also cause a sound of rattling in the compressor. This could indicate that the bearings require to be changed. It is also a good idea to replace pulleys and belts regularly. A worn belt or pulley can slip and lead to compressor overheating and other issues. It is also a great idea to drain your compressor regularly. This will eliminate moisture that can cause corrosion to the motor and other parts. A professional service team will examine for leaks in pipes, and ensure a tight seal on the pressure sensor and compressor.
A puddle of liquid near the compressor could be an indicator of a leak. This could be a risky issue that needs to be addressed right away. If you suspect there is a leak, shut off the air compressor and call an expert.
Check the Thermostat
The thermostat acts like the boss of your entire HVAC system, so it’s not surprising that it’s the first thing a technician will check when trouble occurs. It’s also among the most often neglected maintenance items, but maintaining your thermostat properly is crucial for ensuring your HVAC system’s optimal operation. Common signs that your thermostat requires periodic inspections include incorrect temperature readings, non-responsive controls, or continuous cycling.
Inaccurate Temperature Readings
Over time the sensors on your thermostat may become dirty. This can cause it to display incorrectly. Monitoring your thermostat’s accuracy regularly with a separate thermometer will help you avoid these problems and 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 can have a negative impact on your comfort as well as cause unnecessary wear and tears on the compressor. Fortunately this can be resolved with simply replacing the batteries in your thermostat or resetting its breaker.
If your system isn’t responding to your thermostat at all It’s a good idea to check the breakers that control the thermostat as well as your HVAC equipment. If the breaker tripped then you’ll have to reset it in order for your thermostat to communicate again with the system.
It’s also important to check your thermostat for signs of wear or damage. Look for dust or dirt and ensure that the thermostat is not excessively exposed to the sun. Examine the fan blades for evidence of damage or 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.
Performing basic hvac maintenance on your commercial property is a great way to reduce energy consumption, ensure comfort and prolong the lifespan of your cooling and heating equipment. By identifying problems with your thermostat, resetting the breaker and replacing the batteries, you’ll be able to keep your building comfortable all year. Remember to call a professional if you are having any other problems or unsure of what is going on with your system.
