The Importance of HVAC Maintenance
Maintenance is essential when it is concerned with heating and cooling systems. It will allow you to avoid costly repairs or premature replacement. The majority of HVAC companies offer a service plan where you pay an annual fee to have the system inspected and cleaned, or repaired as required.
You should also carry out some DIY maintenance throughout the year. Cleaning or replacing air filters and keeping the area around outdoor units clear of any debris will ensure the proper airflow.
Clean the Condenser
The coils of the condenser of your air conditioner are the core of the cooling process. If they are dirty your system is likely to struggle to cool and may even fail to function properly. Cleaning them is an essential component of HVAC maintenance. It’s fairly easy to complete. This simple DIY task will eliminate the need for costly repairs, and save you money on your energy bills, and extend the longevity of your AC unit.
It is the first step. It is crucial to shut off the power to your unit. You can do this by turning off the breaker in your electrical box, or by turning off the outdoor unit disconnect switch. This will stop your motors and other electrical components from getting overloaded while cleaning.
Once the power has been shut off, you can start clearing any large debris that could be hindering the condenser’s air. This includes cleaning off any sticks, leaves or other debris that have been accumulating on or around the unit. A shop vacuum equipped with a crevice attachment is a great option to get into the crevices and nooks and remove any dirt, dust or other debris that may have accumulated.
The coils need to be cleaned. Be sure to have a few essential tools on hand prior to beginning. This will include a concentrate for coil cleaning, a pump-up garden sprayer and a garden hose. Spray the coil cleaner on according to the directions on the label of the product and then rinse using the hose. When washing the coils it is essential not to use too much force since the fins can bend easily.
After the coils have been cleaned, you should look them over for any signs of damage. Over time hail, stones thrown by lawnmowers, and other items can damage the coil’s fins. If the fins are bent, a cost-effective tool called a fin comb can straighten them to improve air flow and help the coils function more effectively.
When you have a great coil and fin setup and you are ready to switch on your air conditioner. Check the thermostat every 24 hours to make sure the temperatures are in good shape.
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 of the condenser to your home’s registers, vents, and registers by a system duct. If these ducts aren’t cleaned and sealed, they could be laden with dust and other pollutants. This can block the air filters which reduces the efficiency of the system and puts strain on your AC unit.
Cleaning ductwork can be a difficult task that requires expert equipment and techniques. However, there are some actions you can take on a regular basis to make sure your ducts remain clean and functioning well. To avoid dust and allergens from accumulating in the ducts, you should change your filter on a regular basis. This will also help to keep the clogs from occurring which can lead to reduced system efficiency and high energy bills.
Cleaning the area around the vent openings is a different way to keep your ducts in good shape. Utilizing the hose attachment of your vacuum cleaner, you can eliminate all the cobwebs and crumbs that accumulate over time and help to improve airflow through the vent. It’s also important to make sure your ducts are properly sealed and insulated to keep out moisture which can cause mold and other biological contaminants.
If ducts aren’t cleaned regularly, they could accumulate a variety of contaminants like dust, pet dander and pollen. These particles can exacerbate allergies and respiratory issues especially for children and the elderly. Moisture can cause mold to grow in ductwork, which releases the spores that can be harmful to those with respiratory problems.
It’s generally recommended that you have your ductwork cleaned every three to five years to eliminate these contaminates and ensure that your HVAC system functions efficiently. However If your ducts are sealed properly and you change your filters regularly, duct cleaning may not be necessary at all. The best way to determine for sure is by having your ducts tested. An accredited contractor can use special testing methods to measure the amount of particles in your ductwork, and can recommend suitable cleaning schedules based upon the specific circumstances.
Check the Compressor
The compressor is an essential element of the system. It has to function properly to provide cool air to the ducts. If the compressor isn’t working in the way it should it could affect your productivity and cause downtime for your equipment. Fortunately, preventive maintenance can assist in identifying issues that are minor and prevent unnecessary downtime. Conducting these regular checks can also help you save money by ensuring that your equipment is in good condition for as long as possible.
A decrease in cooling capacity is a typical indication of a problem with the compressor. This can be caused by several different factors. A compressor may be operating too hard due to inadequate airflow. This can wear out the bearings and reduce the lifespan of the compressor. Another common problem is a clogged filter. Filters that are blocked can restrict airflow and cause the compressor to overheat. To prevent this, it is essential to clean or replace the filters on a regular basis, based on the recommendations of the manufacturer.
Additionally, a blocked filter could create a rattling sound inside the compressor. This could indicate that the bearings are worn out and require to be replaced. Regularly replacing the belts and pulleys is a good idea. A worn belt or pulley could cause slipping and result in overheating of the compressor and other issues. It is also a good idea to drain the compressor on a regular basis. This can remove accumulated moisture that can cause corrosion to the motor and other components. A professional service team will also check for air leaks in the hoses as well as a tight seal between the compressor and the pressure switch.
A pool of water in the vicinity of the compressor can be a sign of a leak in the refrigerant. This could be a dangerous problem that should be addressed immediately. If you suspect that there is a leak, turn off the air compressor and call an expert.
Check the Thermostat
It’s not a surprise that technicians will always look at the thermostat first when there’s a problem. It’s also one of the most commonly overlooked maintenance items, but a properly maintained thermostat is crucial for ensuring your HVAC system’s optimal operation. Check your thermostat if find inaccurate temperature readings, ineffective controls or constant cycling.
Inaccurate Temperature Readings
Thermostat sensors can get dirty over time, which can cause the device to display inaccurately. Regularly checking the accuracy of your thermostat by using a separate thermometer can aid in avoiding these issues and conserve energy.
A malfunctioning sensor or calibration could lead to your system continuously switching on and off that is known as short cycling. This can adversely affect your comfort and result in unnecessary wear and tear to the compressor. The problem can be fixed by simply replacing the batteries in the thermostat or resetting the breakers.
Check the breakers for both your thermostat and HVAC equipment If your system isn’t responding to your thermostat. If the breaker has tripped, it will have to be reset to allow the thermostat to communicate with the system.
Check your thermostat for indications of wear and tear. Look for dust or dirt and ensure that the thermostat is not excessively exposed to the sun. Examine the fan blades for evidence of damage or rust. These simple checks can prevent expensive repairs in the future, and ensure your equipment is running as smoothly as possible.
Basic maintenance of hvac is a great strategy to cut down on energy costs and ensure comfort in your commercial property. It can also prolong the lifespan of cooling and heating equipment. You can ensure that your building stays cool throughout the year by identifying problems with your thermostat, then resetting your breaker and changing your batteries. Just remember that in case you experience any other issues, or are unsure about the issue, always call in a professional.
