The Importance of HVAC Maintenance
When it concerns your heating and cooling system, maintenance is the best way to avoid costly repairs or premature replacement. Most HVAC companies offer a service plan that you pay the monthly cost to have your system checked, fixed or cleaned as necessary.
You should also perform some DIY maintenance throughout the year. This includes cleaning or replacing air filters, and keeping the areas around outdoor units clear of any debris to ensure the proper flow of air.
Clean the Condenser
The coils of the condenser of 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 crucial component of HVAC maintenance. It’s also relatively simple to complete. This easy DIY task will save you money, prevent expensive repairs and extend the lifespan of your air cooling.
It is vital to cut off the power source from your unit first. This can be done by turning 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 flooded when cleaning.
When the power is turned off and you are able to remove any large debris that is obstructing the air condenser unit. This includes sweeping away any sticks, leaves, or other debris that have accumulated on or around the unit. A shop vacuum with a crevice tool is a great way to get into the crevices, nooks, and loosen dirt or dust that has accumulated.
The coils must be cleaned. Be sure to have some essential tools in your arsenal before you begin. Included in this are coil cleaning concentrates and a pump-up garden sprayer as well as a garden hose. Spray the coil cleaner on according to the instructions on the label of the product and then rinse using the hose. It is crucial not to apply excessive pressure when washing the coils since the fins could easily be bent.
It is recommended to inspect the coils for signs of damage after cleaning. Over time, hail and rocks dropped by lawnmowers or other items can damage coil fins. If the fins are bent, an affordable tool called a fin comb can straighten them for better air flow and also to aid in the operation of the coils more effectively.
When you have a great coil and fin set up and you are ready to start your air conditioner. After around 24 hours, you can check the thermostat to ensure that the temperatures are in line with normal.
Cleaning the Ductwork
Your HVAC system works by bringing air in from outside, cooling it and distributing it throughout the home. The air travels from the evaporator coil of the condenser unit to the vents and registers of your home through a system of ducts. The ducts could become blocked with dust and other contaminants when they aren’t cleaned and sealed correctly. This can clog the air filters which can reduce the efficiency of your system and strains your AC unit.
In the majority of cases, cleaning the ductwork isn’t an easy task and requires expert equipment and techniques. However, there are some things you can do on a regular basis to ensure that your ducts remain in good condition and function properly. To stop dust and allergens from accumulating in the ducts, it is recommended to change your filter frequently. This also helps to prevent the clogging that can cause a decrease in system efficiency and a high energy bill.
Another way to keep your ducts tidy is to regularly cleaning the area around the vent openings. The hose attachment on your vacuum cleaner will take away all traces of dust, crumbs and other debris that have been accumulating over time. This will improve airflow through the vent. Also, make sure that your ducts have been sealed tight and lined to stop moisture from getting in, which could lead to mold and other biological contaminants.
If ducts aren’t cleaned regularly, they could build up a myriad of contaminants like dust, pet dander and pollen. These particles can exacerbate allergies and respiratory problems, particularly for children and the elderly. Moisture can also cause mold to develop in ductwork, which releases spores that are harmful to people suffering from respiratory issues.
It is recommended to clean your ductwork every three to five year to remove these contaminants and ensure that your HVAC is operating efficiently. However, if your ducts are sealed properly and you clean your filters frequently it is possible that duct cleaning won’t be required 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 gauge the amount of particulates within your ductwork, and will suggest suitable cleaning schedules based upon your particular situation.
Check the Compressor
The compressor is an essential element of the system. It has to be able to supply cool air into the ducts. If the compressor isn’t operating as it should and isn’t functioning properly, it could impact your productivity and cause the equipment to shut down. Regular maintenance can help you identify small issues early, preventing unnecessary downtime. Regular checks can also save you money by making sure that your equipment in the best condition possible.
A typical sign of a compressor issue is a decrease in cooling capacity, however this could be caused by a number of different factors. One possibility is that a 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. A blocked air filter is another common problem. If the filter is clogged, it can reduce the airflow to the compressor and cause overheating. It is crucial to clean or change the filters in accordance with the manufacturer’s recommendations.
A clogged filter may also cause a rattling sound in the compressor. This could indicate that the bearings are worn out and require to be replaced. Regularly replacing the belts and pulleys is recommended. A loose belt or pulley can cause the compressor to overheat and create other problems. It is also a great idea to drain your compressor on a regular basis. This will remove the accumulated moisture that could cause corrosion to the motor and other components. A professional service team will check for leaks in the pipes, and ensure a tight seal on the pressure sensor and compressor.
A small puddle of water around the compressor can be an indication of a refrigerant leak. This could be a risky issue that needs to be addressed immediately. If you suspect that there is a leak, shut off the air compressor and call a professional.
Check the Thermostat
It’s not too surprising that a technician will always examine the thermostat first if there’s a problem. It’s also one of the most commonly overlooked maintenance items, yet a properly maintained thermostat is vital to ensure your HVAC system’s operation. Common indicators that your thermostat is in need of periodic inspections include incorrect temperature readings, ineffective controls, or constant cycling.
Inaccurate Temperature Readings
Over time, the sensors on your thermostat may get dirty. This could cause it to display incorrectly. Regularly checking the accuracy of your thermostat by using a separate thermometer can assist you in avoiding these issues and save energy.
A malfunctioning sensor, or a flawed calibration could cause your system to turn off and on constantly. This is known as short cycling. This could have a negative effect on your comfort and result in excessive wear and tear on the compressor. Fortunately, these issues can often be fixed 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 an excellent idea to look at the breakers that regulate the thermostat and your HVAC equipment. If the breaker has been tripped, it will have to be reset to allow the thermostat to be able to communicate with the system once more.
It’s also important to check your thermostat for any signs of wear or damage. Look for dust or dirt and make sure that the thermostat isn’t excessively exposed to the sun. Finally, the fan blades should be checked for any signs of damage or rust. These simple checks will help prevent costly repairs in the future, and ensure your equipment is operating as smoothly as it is possible.
Basic maintenance of hvac is a great strategy to save energy and keep your comfort in a commercial property. It also increases the life of cooling and heating equipment. It is possible to keep your building comfortable throughout the year by identifying any issues with your thermostat, setting your breaker and changing your batteries. Remember to call an expert if you’re having any other problems or unsure of what is going on with your system.
