The Importance of HVAC Maintenance
When it is about your cooling and heating system, maintenance is essential to avoid costly repairs or premature replacement. The majority of HVAC companies have a service plan where you pay an annual fee to have the system checked and cleaned or repaired when required.
It’s also an excellent idea to carry out some DIY maintenance tasks throughout the year. This includes cleaning or replacing air filters, and keeping the area around outdoor units free of any debris to ensure the proper flow of air.
Clean the Condenser
The coils in your air conditioner’s condenser are the mainstay of the cooling process. If they’re dirty, your system will struggle to cool, and it could even breakdown. Cleaning them is an essential part of HVAC maintenance. It is relatively easy to complete. This easy DIY task will eliminate the need for costly repairs, and save you money on your energy bills and prolong the longevity of your AC unit.
In the beginning, it is essential to cut off the power source to your unit. You can do this by shutting off the breaker at your electrical box or by turning off the outdoor unit disconnect switch. This will protect your motors and electrical components from being over-saturated when cleaning.
Once the power is off, you can begin to clear any large debris obstructing the air condenser unit. This includes cleaning up any sticks, leaves or other debris that have been accumulating on or around the unit. A shop vacuum equipped with a crevice tool is a great tool to reach into the nooks, crannies, and loosen dust or dirt that has built up.
The next step is to clean the coils. Before you do this however, ensure you have several essential tools. These will include a concentrate for coil cleaning and a pump-up garden hose and a garden hose. Spray the coil cleaner in accordance to the instructions on the label, then rinse with a garden hose. It is essential 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 following cleaning. Over time, hail, stones thrown by lawnmowers, and other objects can cause damage to the coil’s fins. Fin combs are a great way to straighten bent fins for better airflow and coil performance.
When you have a great coil and fin setup then you can switch on your air conditioner. Check the thermostat every 24 hours to ensure temperatures are normal.
Clean the Ductwork
Your HVAC system is able to bring air in from outside, cooling it, and distributing it throughout the home. Air is transported from the evaporator inside your condenser unit to your home’s registers and vents via the system duct. The ducts could become blocked with dust and other pollutants when they aren’t cleaned and sealed properly. This could block air filters which reduces the efficiency of your system and strains your AC unit.
Cleaning the ductwork is a challenging task that requires professional equipment and methods. There are a few things you can do regularly to keep your ducts tidy and functioning properly. To prevent dust and allergens accumulating in the ducts, you should change your filter frequently. This will also help prevent clogging, which can lead to a reduced system efficiency and a higher cost for energy.
Another method to keep your ducts clean is by regularly cleaning the area around the vent openings. By using the hose attachment on your vacuum cleaner, you can eliminate all of the cobwebs and crumbs which accumulate over time, and will help to improve air flow through the vent. Also, make sure that your ducts have been sealed tight and protected from moisture getting in, which could cause mold and other biological contaminants.
If ducts aren’t cleaned regularly, they can accumulate a variety of contaminants such as dust, pet dander, and pollen. These particles can worsen allergies and respiratory problems particularly 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 with respiratory ailments.
It’s generally recommended that you have your ducts cleaned every three to five years in order to eliminate the toxins and ensure that your HVAC system functions effectively. However If your ducts are well-sealed and you clean your filters frequently, duct cleaning may not be required at all. The best way to determine the truth is to have your ducts examined. An accredited contractor can use special testing methods to measure the amount of particulates within your ductwork, and will recommend the appropriate cleaning schedules based on your specific situation.
Check the Compressor
The compressor is an important element of the system. It needs to operate correctly to supply cool air to the ducts. If the compressor isn’t operating as it should it could affect your productivity and cause the equipment to shut down. Regular maintenance can help you identify small issues early, preventing excessive downtime. These regular checks will also save you money by keeping your equipment as efficient as possible.
The most common sign of a compressor issue is a loss in cooling capacity, however this could be caused by a number of different factors. A compressor may be operating too hard due to inadequate airflow. This can cause the bearings to wear down and reduce the lifespan of the compressor. Another common problem is a clogged filter. If the filter is blocked it could reduce the airflow to the compressor, which can cause overheating. It is important to change or clean the filters in accordance with the manufacturer’s guidelines.
A blocked filter can also cause rattling noises in the compressor. This can indicate that the bearings are worn out and must be replaced. It is recommended to replace pulleys and belts on a regular basis. A loose pulley or belt could cause slipping and result in compressor overheating and other problems. 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 can examine for air leaks within the hoses and an adequate seal between the compressor and pressure switch.
A puddle of liquid near the compressor could be an indication 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 contact an expert.
Check the Thermostat
It’s not surprising that a technician will check the thermostat first when there’s a problem. A properly maintained thermostat is essential for the efficient operation of your HVAC system. It’s one of the most neglected maintenance items. Examine your thermostat if you notice incorrect temperature readings, ineffective controls, or continuous cycling.
Inaccurate Temperature Readings
Over time the sensors on your thermostat will get dirty. This can cause it to display inaccurately. You can avoid these problems by regularly checking the accuracy of your thermostat by using a a separate thermometer.
A defective sensor or a faulty calibration can cause your system to turn off and on constantly. This is known as short cycling. This can negatively impact your comfort and cause unnecessary wear and tear to the compressor. Fortunately the majority of these issues can be resolved with the simple act of replacing the thermostat’s batteries or resetting the breaker.
Check the breakers for both your thermostat and HVAC equipment if your system doesn’t respond to your thermostat. If the breaker tripped, you will need to reset it to allow your thermostat to be able to communicate with the system.
Examine your thermostat for signs of wear and damage. Find evidence of dust or dirt, and make sure the thermostat isn’t exposed to sunlight. Lastly, the fan blades need to be examined for signs of rust or damage. This simple check will help avoid costly repairs in the future, and ensure that your equipment operates as smoothly as it possibly can.
Performing basic hvac maintenance on your commercial property is a great way to reduce energy consumption, ensure comfort and prolong the life of your heating and cooling equipment. By identifying any issues with your thermostat, setting the breaker and replacing the batteries, you’ll be able to keep your building warm all year round. Be sure to call a professional if you have any other issues or are unsure about the issue you should always consult a professional.
