The Importance of HVAC Maintenance
When it comes to your heating and cooling system, maintenance is the key to avoiding costly repairs or early-than-necessary replacement. Most HVAC companies offer a service plan that charges a monthly fee to have your system checked, repaired or cleaned as needed.
It is also recommended to perform DIY maintenance throughout the year. Cleaning or replacing air filters and keeping the area surrounding the outdoor units free of clutter will help ensure the proper flow of air.
Clean the Condenser
The coils inside the condenser in your air conditioner are the core of the cooling process. If they are dirty your system will struggle to cool properly and may even break down. Cleaning them is a crucial part of HVAC maintenance. It’s fairly easy to do. This easy DIY task can prevent the need for costly repairs, save you money on your energy bills and prolong the lifespan of your air conditioning unit.
First and foremost, it is essential to cut off the power supply to your unit. This can be accomplished by shutting off the breaker in your electrical box or by turning off the outdoor unit disconnect switch. This will safeguard your motors and electrical components from being oversaturated during cleaning.
Once the power is off, you can begin removing any large debris that could be blocking the air condenser. This includes sweeping up any leaves, sticks, or other debris that have built up on or around the unit. Utilizing a shop vacuum that has a crevice attachment is a great method to reach into the crevices and nooks and loosen any dirt, dust or other debris that has collected.
The coils need to be cleaned. Before doing this, though, make sure you have some essential tools. These include a concentrate of the coil cleaner and a pump-up garden hose and a garden hose. Spray the coil cleaner on in accordance with the directions on the product label and rinse with the hose. It is crucial not to apply excessive pressure when washing the coils, because the fins may be bent.
After the coils have been cleaned, inspect them for any indications of damage. Over time, hail and rocks dropped by lawnmowers or other items could damage the coil fins. If the fins are bent, an affordable tool known as a fin-comb can straighten them for better air flow and also to help the coils function more efficiently.
Once the coils and fins are in good shape If you are satisfied with the condition of your fins and coils, return to your home and turn on your air conditioner. Make sure to check the thermostat after 24 hours to ensure temperatures are within the normal range.
Clean the Ductwork
Your HVAC system works by bringing air from outside, cooling it, and then distributing it throughout your home. The air travels from the evaporator coil in your condenser unit and then to your house’s vents and registers through a duct system. These ducts may become clogged with dust and other contaminants when they aren’t cleaned and sealed properly. This could block air filters which can reduce the effectiveness of your system and burdens your AC unit.
Cleaning ductwork can be a difficult task that requires specialized equipment and methods. However, there are some actions you can take on a regular basis to make sure your ducts stay clean and well-functioning. To avoid dust and allergens from accumulating in the ducts, you should change your filter frequently. This can also help prevent clogging, which can lead to a reduced system efficiency and a higher cost for energy.
Another way to help keep your ducts clean is by regularly cleaning the area around vent openings. The hose attachment on your vacuum cleaner will get rid of all the cobwebs, crumbs and other debris that have built up over time. This will increase airflow through the vent. Also, make sure that your ducts have been sealed well and are insulated to prevent moisture from entering, which can lead to mold and other biological contaminants.
If ducts are not cleaned regularly, they could collect a variety of pollutants such as dust, pet dander, and pollen. These particles can cause a flare-up of respiratory and allergies, especially for children and the elderly. The moisture in ductwork can result in the growth of mold which releases spores into the air and poses health concerns for those who suffer from respiratory ailments.
It is recommended to clean your ducts every three to five year to remove these contaminants and ensure that your HVAC is operating efficiently. If your ducts are sealed well and you change your filter regularly It may not be necessary to clean them. The best way to determine the truth is to have your ducts examined. A certified contractor can employ special testing methods to measure the amount of particulates in your ductwork, and will recommend the suitable cleaning schedules based upon your specific situation.
Check the Compressor
The compressor is an essential component of the system. It must be able to provide cool air to the ducts. If the compressor isn’t functioning as it should it could affect your productivity and result in equipment downtime. Regular maintenance can help you identify minor issues early, preventing unnecessary downtime. Regular checks can also save you money by keeping your equipment in the best condition possible.
A reduction in cooling capacity is a common sign of a problem with the compressor. It could be caused by several different factors. A compressor may be operating too hard due to poor airflow. This can wear out the bearings and diminish the life of the compressor. Another issue that is common is a clogged filter. If the filter is clogged it could reduce the airflow to the compressor, which can cause overheating. To prevent this, it is essential to clean or change the filters on a regular basis, based on the manufacturer’s recommendation.
In addition, a clogged filter could create a rattling sound inside the compressor. This could indicate that the bearings must be replaced. It is also a good idea to replace pulleys and belts regularly. A loose pulley or belt could cause slipping and result in compressor overheating and other issues. It is recommended to drain the compressor regularly. This can remove accumulated moisture that could cause corrosion to the motor and other components. A professional service team will also check for leaks in the pipes, and ensure an adequate seal around the pressure sensor and compressor.
A puddle of liquid near the compressor could be a sign of leak. This can be a dangerous issue and should be repaired immediately. If you suspect that there is a leak, shut off the air compressor and call a professional.
Check the Thermostat
It’s not a surprise that a technician will always examine the thermostat first if there’s any issue. It’s also one of the most commonly overlooked maintenance items, but a properly maintained thermostat is crucial for ensuring your HVAC system’s operation. Examine your thermostat if you observe inaccurate temperature readings, ineffective controls or constant cycling.
Inaccurate Temperature Readings
Thermostat sensors can get dirty over time, which may cause the device to display inaccurately. Monitoring your thermostat’s accuracy regularly with a separate thermometer will assist you in avoiding these issues and help you save energy.
A malfunctioning sensor or calibration may lead to your system continuously switching off and on, which is referred to as short cycling. This could have a negative effect on your comfort as well as cause excessive wear and tear on the compressor. Fortunately, these issues can often be resolved with the simple act of replacing the thermostat’s batteries or resetting its breakers.
If your thermostat 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 been tripped, it will need to be reset in order for the thermostat to connect with the system once more.
It is also essential to examine your thermostat for any signs of wear or damage. Find indications of dust or dirt, and make sure the thermostat isn’t too exposed to sunlight. Lastly, the fan blades need to be examined for any signs of damage or rust. These simple checks can prevent costly repairs in the future and will ensure that your equipment operates as smoothly as it can.
Basic HVAC maintenance is a great strategy to reduce energy costs and ensure comfort in your commercial property. It will also extend the lifespan of your cooling and heating equipment. You can keep your building comfortable throughout the year by identifying any issues with your thermostat, resetting your breaker, and then replacing your batteries. Make sure that if you have any other issues or aren’t sure what’s wrong with your system, always call in an expert.
