The Importance of HVAC Maintenance
When it is about your heating and cooling system, maintenance is the best way to avoid costly repairs or premature replacement. The majority of HVAC companies offer a service plan that charges an affordable monthly fee to have the system checked, repaired or cleaned when needed.
It’s also a good idea to perform a few DIY maintenance tasks throughout the year. These include cleaning or replacing air filters and keeping the space around outdoor units free of any debris to ensure proper airflow.
Clean the Condenser
The coils that make up the condenser of your air conditioner are the heart of the cooling process. If they’re dirty, you system will struggle to cool and could even fail. Cleaning them is a crucial part of HVAC maintenance. It’s relatively simple to complete. This simple DIY task will save you money, avoid costly repairs and prolong the life of your air cooling.
It is crucial to disconnect the power source from your unit first. This can be accomplished by shutting off the breaker inside your electrical box or at the outdoor unit disconnect switch. This will prevent your motors and electrical components from being flooded when cleaning.
After the power has been shut off and you are able to clear any large debris blocking the air condenser unit. This includes cleaning off any sticks, leaves, or other debris that has been accumulating on or around the unit. Utilizing a shop vacuum that has a crevice attachment is a great way to reach into the nooks and crannies and get rid of any dirt, dust or other debris that has collected.
The coils must be cleaned. Make sure you have a few essential tools available before you begin. These will include a coil cleaner concentrate, 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 rinse with the hose. It is essential not to apply excessive pressure when washing the coils, because the fins may be bent.
After the coils have been cleaned, you should inspect them for any signs of damage. Over time hail, stones thrown by lawnmowers, and other items can damage the coil fins. If the fins are bent, a low-cost tool called a fin comb can straighten them for better air flow and also to help the coils function more efficiently.
If the fins and coils are in good shape If you are satisfied with the condition of your fins and coils, return to your house and start your air conditioning. 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 your home. The air is moved from the evaporator coil in your condenser unit and then to your home’s vents and registers through a network of ducts. The ducts could become blocked with dust and other contaminants if they are not cleaned and sealed properly. This can block the air filters, which in turn reduces system efficiency and puts strain on your AC unit.
Cleaning ductwork can be a difficult task that requires professional equipment and techniques. There are a few things you can do to ensure that your ducts are clean and working well. First, you should change your filter on a regular basis to keep dust and allergens out of building into the ducts. This will also help to stop the clogging that could cause a decrease in system efficiency and a high energy bill.
Another method to keep your ducts tidy is to regularly cleaning the area around the vent openings. The hose attachment on your vacuum cleaner will remove all the cobwebs, crumbs and other messes that have been accumulating over time. This will increase the flow of air through the vent. It is also important to ensure that your ducts are sealed tight and insulated to prevent moisture from entering, which can lead to mold and other biological contaminants.
If ducts aren’t regularly cleaned, they may accumulate a variety of contaminants such as dust, pet dander, and pollen. These particles can exacerbate respiratory and allergy conditions particularly in the elderly and children. Moisture can also cause mold to grow in the ductwork, which releases microbes that can harm those with respiratory problems.
It is generally recommended to have your ducts cleaned every three to five years to remove the toxins and ensure that your HVAC system is working efficiently. However If your ducts are sealed properly and you clean your filters frequently the cleaning of your ducts may not be required at all. The best way to be able to tell for certain is to have your ducts tested. A contractor who is accredited by the EPA can use special testing methods in order to determine the amount of particles found in your ductwork. They will then suggest cleaning schedules that are appropriate for your specific situation.
Check the Compressor
The compressor is an essential element of the system. It must function correctly to supply cool air to the ducts. If the compressor isn’t operating in the way it should, it can affect your productivity and cause equipment downtime. Preventive maintenance can help spot small issues early, preventing excessive downtime. Performing these routine checks can also save you money by ensuring that your equipment is in good condition for as long as possible.
A common sign of a compressor issue is a reduction in cooling capacity, although this could be caused by various factors. One possibility is that a compressor could be under-performing due to inadequate airflow. This can wear out the bearings and decrease the lifespan of the compressor. A blocked air filter is another common issue. If the filter has become clogged, it can reduce the airflow to the compressor and lead to overheating. It is essential to clean or change the filters according to the manufacturer’s guidelines.
Additionally, a blocked filter can also cause rattling noises in the compressor. This could be an indication that the bearings must be replaced. It is recommended to replace pulleys and belts regularly. A loose belt or pulley can cause the compressor to overheat and create other issues. It is recommended to drain the compressor regularly. This will eliminate 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.
Lastly, a puddle of water near the compressor can be a sign of a leak in the refrigerant. This is a serious problem and needs to be fixed right away. If you suspect there is a leak, shut off the air compressor and contact a professional.
Check the Thermostat
The thermostat is like the boss of your HVAC system, so it’s not a surprise that it’s the first thing a technician will look at when trouble occurs. A well-maintained thermostat is essential for the smooth operation of your HVAC system. It’s one of the most overlooked maintenance items. Check your thermostat if you notice incorrect temperature readings, unresponsive controls, or constant cycling.
Inaccurate Temperature Readings
Thermostat sensors may become dirty over time, which can cause the thermostat to display inaccurately. You can avoid this issue by checking the accuracy of your thermostat using a an additional thermometer.
A faulty sensor or calibration can also cause your system to keep turning on and off that is known as short cycling. This can have a negative impact on your comfort as well as cause unnecessary wear and tears on the compressor. This issue can be solved by simply replacing the thermostat’s batteries or resetting the breaker.
If your system isn’t responding to your thermostat at all it’s recommended to examine the breakers that regulate the thermostat as well as your HVAC equipment. If the breaker has been tripped, it will require resetting to allow the thermostat to be able to communicate with the system again.
Check your thermostat for indications of wear and damage. Look for signs of dirt or dust and ensure that the thermostat isn’t overly exposed to sunlight. Check the fan blades for evidence of damage or rust. These simple checks can prevent costly repairs in the future, and ensure your equipment is operating as efficiently as it can.
Conducting basic HVAC maintenance on your commercial building is an excellent way to cut down on the cost of energy, maintain comfort and extend the longevity of your cooling and heating 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. Be sure to call a professional should you encounter any other issues, or are unsure of what’s wrong with your system, always call in a professional.
