The Importance of HVAC Maintenance
When it comes to your heating and cooling system, maintenance is the key to avoiding costly repairs or premature replacement. Most HVAC companies offer a service plan where you pay an affordable monthly fee to get the system checked, repaired or cleaned when needed.
It’s also recommended to do some of the DIY maintenance tasks throughout the year. Cleaning or replacing air filters, and keeping the area around outdoor units free of any debris will ensure the proper flow of air.
Clean the Condenser
The coils of your condenser for your air conditioner are the primary component of the cooling process. If they’re dirty, your system will struggle to cool, and it could even fail. Cleaning them is a vital component of HVAC maintenance. Fortunately, it is also relatively simple to complete. This easy DIY task can avoid the need for expensive repairs, save you money on your energy bills and extend the longevity of your AC unit.
In the beginning, it is crucial to shut off the power source to your unit. This can be accomplished by shutting off the breaker inside your electrical box or by turning off the outdoor unit disconnect switch. This will stop your motors and other electrical components from getting overloaded during cleaning.
Once the power is off it is now time to clear any large debris blocking the air condenser unit. This will include taking away any sticks, leaves, or other debris that has been accumulating on or around the unit. Using a shop vacuum with a crevice attachment is a great option to reach into the nooks and crevices and remove any dust, dirt or other debris that may have accumulated.
The coils require to be cleaned. Before you begin, though, make sure that you have in your possession a few key tools. These will include a coil cleaner concentrate and a pump-up garden sprayer and a garden hose. Spray the coil cleaner according to the instructions on the product label and rinse with the hose. It is crucial not to apply too much pressure when washing the coils, because the fins may be bent.
It is recommended to inspect the coils for signs of damage following cleaning. Over time, hail and rocks thrown from lawnmowers or other objects can cause damage to coil fins. If the fins are bent, a cost-effective tool known as a fin-comb can straighten them for better air flow and also to aid in the operation of the coils more efficiently.
Once the coils and fins are in good shape, you can return to your home and switch on your air conditioner. Check the thermostat every 24 hours to ensure temperatures are normal.
Cleaning the Ductwork
Your HVAC system is designed to bring outside air into your home, then cool it and then distribute it throughout your house. The air is moved from the evaporator coil in your condenser unit to your home’s vents and registers through a system of ducts. If these ducts aren’t properly cleaned and sealed, they can become loaded with dust and other pollutants. This can block the air filters which reduces the efficiency of your system and can strain your AC unit.
In the majority of instances, cleaning ductwork isn’t an easy job and requires the help of professional equipment and techniques. However, there are some things you can do on a regular basis to ensure your ducts remain clean and functioning well. First, you should change your filter regularly to keep dust and allergens out of building up in the ducts. This can also help stop clogging, which could cause a decrease in efficiency and higher energy bills.
Vacuuming the area around the vent openings is a different method to keep your ducts in good shape. Utilizing the hose attachment of your vacuum cleaner, you can get rid of all cobwebs and crumbs that accumulate over time, and help to improve air flow through the vent. You should also make sure that your ducts are sealed well and are protected from moisture entering, which can cause mold and other biological contaminants.
If ducts aren’t cleaned regularly, they can accumulate a variety of contaminants like dust, pet dander, and pollen. These particles can exacerbate allergies and respiratory issues, particularly in children and the elderly. Moisture can also cause mold to grow in the ductwork, which releases microbes that can harm those suffering from respiratory ailments.
It is recommended to clean your ducts once every three to five year to eliminate these contaminates and ensure that your HVAC is operating efficiently. If your ducts have been sealed well and you change your filter regularly It may not be necessary to clean them. You can be certain by having your ducts checked. A certified contractor can employ specific testing methods to determine the amount of particles in your ductwork and will suggest appropriate cleaning schedules that are based on the specific circumstances.
Check the Compressor
The compressor is an essential element of the system. It must function properly to provide cool air to the ducts. If the compressor isn’t working as it should it could affect your productivity and lead to equipment downtime. Preventive maintenance can help identify minor issues earlier, avoiding unnecessary downtime. Performing these routine checks can also help you save money by keeping your unit in good shape for as long as possible.
A typical sign of a compressor issue is a reduction in cooling capacity, although it could be caused by a number of different factors. One possibility is that the compressor may be working too hard due to poor airflow. This could cause bearings to wear out and reduce the lifespan of the compressor. Another common issue is a blocked filter. Filters that are clogged can restrict airflow and cause the compressor to overheat. To prevent this from happening, it is crucial to clean or change the filters on a regular basis, based on the recommendations of the manufacturer.
A blocked filter can cause a rattling sound in the compressor. This could indicate that the bearings must be replaced. Regularly replacing the belts and pulleys is recommended. A pulley or belt that is loose can cause the compressor to overheat and create other issues. It is also a good idea to drain the compressor regularly. This will remove the accumulated moisture that can cause corrosion to the motor and other components. A professional service team will also examine for leaks in pipes, and ensure an adequate seal around the pressure sensor and compressor.
A small puddle of water around the compressor can be an indication of a leak in the refrigerant. This can be a dangerous problem and needs to be fixed right away. If you suspect there is a leak, switch off the air compressor and call a professional.
Check the Thermostat
The thermostat is kind of like the boss of your entire HVAC system, and it’s not a surprise that it’s the first thing that a technician will look at when trouble arises. It’s also one of the most commonly overlooked maintenance items, yet maintaining your thermostat properly is essential to ensure your HVAC system’s proper operation. Check your thermostat if you observe inaccurate temperature readings, non-responsive controls, or continuous cycling.
Inaccurate Temperature Readings
Thermostat sensors may become dirty over time, which may cause the thermostat to display incorrectly. Regularly checking your thermostat’s accuracy with a separate thermometer will help you avoid these problems and save energy.
A malfunctioning sensor, or a faulty calibration can cause your system to turn off and on continuously. This is called short cycling. This can negatively impact your comfort and result in unnecessary wear and tear on the compressor. Fortunately, these issues can often be corrected by the simple act of replacing the batteries in your thermostat or resetting the breaker.
If your system isn’t responding to your thermostat in any way It’s recommended to examine the breakers that regulate the thermostat and your HVAC equipment. If the breaker has been tripped, it will require resetting to allow the thermostat to be able to communicate with the system again.
Check your thermostat for signs of wear and tear. Look for evidence of dust or dirt and ensure that the thermostat isn’t too exposed to sunlight. Lastly, the fan blades must be inspected for signs of damage or rust. These simple checks will prevent costly repairs in the future and will ensure that your equipment runs as smoothly as possible.
Basic hvac maintenance is a great way to cut down on energy costs and maintain comfort in your commercial space. It will also extend the lifespan of heating and cooling equipment. By identifying any issues with your thermostat, setting the breaker and replacing the batteries in the process, you’ll be able keep your building cool all year. Just remember that should you encounter any other issues, or are unsure about the issue, always call in an expert.
