The Importance of HVAC Maintenance
Maintenance is essential when it concerns heating and cooling systems. It will allow you 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 as needed.
It’s also recommended to do a few DIY maintenance tasks throughout the year. These include 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 inside the condenser in your air conditioner are the heart of the cooling process. If they are dirty your system is likely to struggle to cool and could even fail. Cleaning them is a crucial part of HVAC maintenance. Fortunately, it is also relatively simple to complete. This easy DIY task will eliminate the need for expensive repairs, and save you money on your energy bills and prolong the lifespan of your air conditioning unit.
It is vital to cut off power from your unit before you disconnect it. This can be accomplished by turning off the breaker in your electrical box or at the outdoor unit disconnect switch. This will keep your motors and other electrical components from becoming oversaturated while cleaning.
When the power is turned off it is now time to clear any large debris blocking the air condenser unit. This includes sweeping off any sticks, leaves, or other debris that have built up on or around the unit. Utilizing a shop vacuum that has crevice attachments is a great way to reach into the nooks and crannies and remove dust, dirt or other debris that may have accumulated.
The coils need to be cleaned. Make sure you have some essential tools on hand prior to beginning. Included in this are coil cleaning concentrates, a pump up garden sprayer and the garden hose. Spray the coil cleaner according to the instructions on the label, then rinse with the hose. When washing the coils it is essential not to use excessive force since the fins can bend easily.
It is recommended to inspect the coils for signs of damage after cleaning. Over time, hail and rocks that are thrown by lawnmowers and other items can damage coil fins. If the fins are bent, a low-cost tool known as 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 set up, you can switch on your air conditioner. After approximately 24 hours, you can examine the thermostat and ensure that temperatures are normal.
Clean the Ductwork
Your HVAC system is designed to bring outside air into your home, cool it, and then distribute it throughout the home. The air moves from the evaporator coil inside your condenser unit and then to your home’s vents and registers through a network of ducts. If these ducts aren’t cleaned and sealed, they could be laden with dust and other pollutants. This can block the air filters which can reduce the effectiveness of your system as well as strains your AC unit.
In the majority of cases, cleaning the ductwork is not an easy job and requires professional equipment and techniques. There are some things you can do to ensure that your ducts are clean and functioning properly. First, change your filter on a regular basis to keep dust and allergens out of building in the ducts. This can also help keep the clogs from occurring which can lead to reduced system efficiency and a high energy bill.
Another way to keep your ducts clean is by regularly cleaning the area around the vent openings. The hose attachment of your vacuum cleaner will get rid of all traces of dust, crumbs and other messes that have built up over time. This will increase the flow of air through the vent. Also, make sure that your ducts are sealed tightly and are lined to stop moisture from getting in, which could result in mold and other biological contaminants.
If ducts are not cleaned regularly, they can accumulate a variety of contaminants like dust, pet dander, and pollen. These particles can cause allergies and respiratory issues particularly in the elderly and children. 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 ducts cleaned every three to five years to eliminate these contaminates and ensure that your HVAC system functions effectively. If your ducts are well-sealed, and you change your filter regularly It may not be necessary to clean them. You can only be sure by having your ducts checked. A contractor who is accredited by the EPA can employ special testing techniques to determine the amount of particles that are present in your ductwork. They will then suggest cleaning schedules that are appropriate for your particular situation.
Check the Compressor
The compressor is an essential component of the system. It has to be able to supply cool air into the ducts. If the compressor isn’t functioning as it should it could affect your productivity and lead to equipment downtime. Fortunately, preventive maintenance is able to assist in identifying issues that are minor and avoid excessive downtime. These regular checks will also save you money by ensuring that your unit as good as possible.
A reduction in cooling capacity is a typical sign of a problem in a compressor. This could be caused by a variety of causes. One possibility is that a compressor could be overworking because of poor airflow. This can cause the bearings to wear down and reduce the lifespan of the compressor. Another issue that is common is a blocked filter. If the filter is blocked it could reduce the airflow to the compressor and cause overheating. It is essential to clean or replace the filters according to manufacturer’s recommendations.
A blocked filter may also cause a rattling sound in the compressor. This could be an indication that the bearings must be replaced. Regularly replacing belts and pulleys is an excellent idea. A loose belt or pulley can slip, causing the compressor to overheat and cause other issues. It is also a good idea to drain the compressor on a regular basis. This will eliminate moisture that can cause corrosion to the motor and other components. A professional service team will also look for leaks in the pipes, and ensure a tight seal on the pressure sensor and compressor.
A puddle of liquid close to the compressor could be an indicator of leak. This could be a risky issue and should be repaired immediately. If you suspect that there is a leak, turn off the air compressor. Consult a professional.
Check the Thermostat
The thermostat is like the head of your HVAC system, so it’s not a surprise that it’s the first thing that a technician will inspect when a problem occurs. A properly maintained thermostat is crucial to the efficient operation of your HVAC system. It’s one of the most neglected maintenance items. Common indicators that your thermostat is in need of a check-up include incorrect temperature readings, unresponsive controls, or constant cycling.
Inaccurate Temperature Readings
Thermostat sensors can get dirty over time, which can cause the thermostat to display inaccurately. You can avoid these problems by checking the accuracy of your thermostat by using a the use of a separate thermometer.
A malfunctioning sensor, or a faulty calibration can cause your system to cycle on and off continuously. This is known as short cycling. This can adversely affect your comfort and cause unnecessary wear and tear to the compressor. Fortunately this can be fixed with simply replacing the thermostat’s batteries or resetting the breaker.
Check the breakers for your HVAC equipment and thermostat if your system doesn’t respond to your thermostat. If the breaker has tripped, it will require resetting to allow the thermostat to connect with the system once more.
Examine your thermostat for signs of wear and tear. Look for evidence of dust or dirt, and make sure the thermostat isn’t overly exposed to sunlight. The fan blades must be inspected for signs of rust or damage. These simple checks can help avoid costly repairs in the near future, and will ensure that your equipment is operating as efficiently as possible.
Basic HVAC maintenance is a great way to reduce energy costs and ensure comfort in your commercial space. It can also prolong the lifespan of heating and cooling equipment. You can ensure that your building stays cool throughout the year by identifying any issues with your thermostat, then resetting your breaker, and then replacing your batteries. Remember to call a professional if you are experiencing any other issues or unsure of what is going on with your system.
