The Importance of HVAC Maintenance
When it concerns your heating and cooling system, routine maintenance is essential to avoid costly repairs or early-than-necessary replacement. The majority of HVAC companies offer a service plan that you pay a low monthly rate to have your system checked, fixed or cleaned when necessary.
It’s also an excellent idea to carry out some of the DIY maintenance tasks throughout the year. Cleaning or replacing air filters, and keeping the area around outdoor units free of debris will promote proper airflow.
Clean the Condenser
The coils in your condenser for your air conditioner are the primary component of the cooling process. If they are dirty, your system is likely to struggle to cool and may even break down. Cleaning them is a crucial part of HVAC maintenance. It is, fortunately, quite simple to do. This easy DIY task will save you money, prevent costly repairs, and increase the lifespan of your air cooling.
In the beginning, it is essential to cut off the power supply to your unit. You can do this by turning off the breaker on your electrical box or the outdoor unit disconnect switch. This will safeguard your electrical components and motors from being flooded during cleaning.
After the power has been shut off, you can begin clearing any large debris that may be hindering the condenser air. 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 crevices and nooks and loosen any dirt, dust or other debris that has collected.
The coils require to be cleaned. Make sure you have the necessary tools available prior to beginning. These will include a coil cleaner concentrate, a pump-up garden sprayer and a garden hose. Spray the coil cleaner according to the directions on the label of the product and rinse with the hose. When washing the coils it is important not to apply too much force as the fins can bend easily.
You should examine the coils for signs of damage following cleaning. Over time, hail and rocks thrown from lawnmowers or other items could damage the coil fins. Fin combs are a great way to straighten bent fins for better airflow and performance of the coil.
When the fins and coils are in good condition, you can return to your home and turn on your air conditioner. Check the thermostat every 24 hours to ensure temperatures are within the normal range.
Clean the Ductwork
Your HVAC system is designed to bring air from outside into your home, cool it and then distribute it throughout your home. The air is transported from the evaporator inside your condenser to your home’s registers and vents via the system of ducts. The ducts could become blocked with dust and other pollutants when they aren’t cleaned and sealed properly. This can block the air filters, which decreases the effectiveness of your system and can strain your AC unit.
Cleaning ductwork can be a challenging task that requires expert equipment and methods. However, there are a few actions you can take regularly to ensure your ducts are clean and well-functioning. First, change your filter regularly to keep dust and allergens from building into the ducts. This also helps to stop the clogging that could cause a decrease in system efficiency and a high energy bill.
Cleaning the area around the vent openings is a different way to keep your ducts clean. Using the hose attachment on your vacuum cleaner, you can eliminate all cobwebs and crumbs which accumulate over time, and will assist in improving airflow through the vent. It is also important to make sure your ducts are properly sealed and insulated to keep out moisture which can cause mold and other biological contaminants.
Ducts that aren’t cleaned on a regular basis are likely to be contaminated with a myriad of contaminants, such as dust, pet dander and pollen. These particles can worsen allergies and respiratory issues especially in children and the elderly. Moisture in ductwork can also lead to the growth of mold, which releases spores into the air and can cause health issues for those with respiratory ailments.
It is generally recommended that you have your ducts cleaned every three to five years to eliminate the toxins and ensure that your HVAC system is working effectively. If your ducts are sealed properly, and you regularly change your filter it might not be necessary to clean them. The best way to determine the truth is to have your ducts examined. A contractor who is accredited by the EPA can employ special testing methods in order to determine the amount of particles found in your ductwork. They can then recommend cleaning schedules that are appropriate for your particular situation.
Check the Compressor
The compressor is an important component of the system. It needs to operate properly to deliver cool air to the ducts. If the compressor isn’t functioning in the way it should it could affect your productivity and lead to the equipment to shut down. Regular maintenance can help you identify minor issues early, preventing unnecessary downtime. Regular checks can also save you money by making sure that your unit as good as possible.
A decrease in cooling capacity is a typical sign of a problem in the compressor. It could be caused by several different causes. A compressor may be working too hard due to inadequate airflow. This could cause bearings to wear down and reduce the lifespan of the compressor. Another common problem is a clogged filter. Filters that have become blocked can hinder airflow and cause the compressor to overheat. It is important to clean or replace the filters according to manufacturer’s instructions.
A blocked filter can cause a rattling sound in the compressor. This could indicate that the bearings are worn out and need to be replaced. Regularly replacing the belts and pulleys is a good idea. A loose pulley or belt can cause slippage and cause compressor overheating and other issues. It is also a good idea to drain your compressor frequently. This will remove moisture that can cause corrosion to the motor and other parts. A professional service team will also check for leaks in the hoses, and an adequate seal around the compressor and pressure sensor.
A puddle of liquid near the compressor could be an indication of a leak. This could be a dangerous issue that needs to be addressed immediately. If you suspect that there is a leak, turn off the compressor that is running and then contact a professional.
Check the Thermostat
The thermostat is kind of like the head of your HVAC system, so it’s not surprising that it’s the first thing a technician will look at when trouble occurs. It’s also one of the most commonly overlooked maintenance items, yet maintaining your thermostat properly is essential to ensure your HVAC system’s optimal operation. The most common signs that your thermostat needs an inspection include inaccurate temperature readings, unresponsive controls, or continuous cycling.
Inaccurate Temperature Readings
Thermostat sensors may become dirty over time, which could cause the thermostat to display incorrectly. You can avoid this issue by ensuring the accuracy of your thermostat by using a an additional thermometer.
A malfunctioning sensor or calibration can also result in your system constantly switching on and off that is known as short cycling. This can adversely affect your comfort and cause excessive wear and tear on the compressor. These issues can be resolved by simply replacing the thermostat’s batteries or resetting the breaker.
If your system isn’t responding to your thermostat in any way It’s an excellent idea to look at the breakers that control the thermostat and your HVAC equipment. If the breaker tripped then you’ll have to reset it in order for your thermostat to be able to communicate with the system.
It’s also crucial to examine your thermostat for any signs of wear or damage. Check for signs of dirt or dust, and make sure the thermostat isn’t overly exposed to sunlight. The fan blades must be inspected for any signs of damage or rust. These simple checks will prevent costly repairs in the future, and ensure that your equipment runs as smoothly as it can.
Basic HVAC maintenance is a great way to save energy and maintain comfort in your commercial property. It can also prolong the lifespan of your cooling and heating equipment. It is possible to keep your building comfortable throughout the year by identifying problems with your thermostat, then resetting your breaker and changing your batteries. Just remember that if you have any other issues or are unsure about what’s wrong with your system, always call in an expert.
