The Importance of HVAC Maintenance
When it comes to your heating and cooling system, regular maintenance is essential to avoid costly repairs or replacements that are not needed as soon as they should be. Most HVAC companies offer a service plan that you pay an affordable monthly fee to have your system checked, repaired or cleaned when needed.
You should also perform some DIY maintenance throughout the year. These include cleaning or replacing air filters and keeping the space around outdoor units free of clutter to allow for the proper flow of air.
Clean the Condenser
The coils in your air conditioner’s condenser are the core of the cooling process. If they are dirty, you system will struggle to cool, and it could even breakdown. This is why cleaning them is a vital part of HVAC maintenance. Fortunately, it is also fairly easy to do. This easy DIY task will help you save money, avoid costly repairs and prolong the life span of your air cooling.
In the beginning, it is important to disconnect the power to your unit. You can do this by turning off the breaker on your electrical box or by turning off the outdoor unit disconnect switch. This will keep your motors and other electrical components from becoming oversaturated during cleaning.
Once the power is off, you can begin clearing any large debris that could be hindering the condenser’s air. This includes taking away any sticks, leaves, or other debris that has accumulated on or around the unit. Utilizing a shop vacuum that has crevice attachments is a great method to reach into the crevices and nooks and get rid of any dust, dirt or other debris that has collected.
Next, it is time to clean the coils. Before you begin, though, make sure you have several essential tools. Included in this are a coil cleaning concentrate as well as a pump-up garden sprayer, and a garden hose. Spray the coil cleaner on according to the directions on the product label and then rinse it off using the hose. It is crucial not to apply excessive pressure when washing the coils, because the fins may be bent.
After the coils have been cleaned, you should look them over for any indications of damage. Over time, the impact of hail and stones that are thrown by lawnmowers and other items could damage the coil fins. Fin combs can be used to straighten bent fins for better airflow and performance of the coil.
Once you have a good coil and fin setup then you can switch on your air conditioner. After about 24 hours, you can check the thermostat and ensure that the temperatures are in line with normal.
Clean the Ductwork
Your HVAC system is able to bring air from outside, cooling it, and distributing it throughout the home. Air is transported from the evaporator in your condenser unit to your home’s registers, vents, and registers by a system of ducts. If these ducts aren’t cleaned and sealed, they may be laden with dirt and other contaminates. This clogs the air filters which reduces the efficiency of the system and puts strain on your AC unit.
In most instances, cleaning ductwork is not an easy task that requires professional equipment and techniques. There are some things you can do regularly to ensure that your ducts are clean and in good working order. To stop dust and allergens accumulating in the ducts, it is recommended to 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.
Another method to keep your ducts clean is by regularly vacuuming the area around the vent openings. Using the hose attachment on your vacuum cleaner can remove all cobwebs and crumbs which accumulate over time, and will aid in improving airflow through the vent. Also, make sure that your ducts have been sealed tight and protected from moisture entering, which can cause mold and other biological contaminants.
Ducts that aren’t cleaned on a regular basis can be filled with a myriad of pollutants, including dust, pet dander and pollen. These particles can cause a flare-up of respiratory and allergies particularly for children and the elderly. The moisture in ductwork can cause the growth of mold which releases spores into air and poses health concerns for those suffering from respiratory ailments.
It is generally recommended to have your ductwork cleaned every three to five years to eliminate these contaminates and ensure that your HVAC system is operating effectively. If your ducts are well-sealed, and you regularly change your filter It may not be necessary to clean them. You can be certain by having your ducts examined. A certified contractor can employ specific testing methods to determine the amount of particles within your ductwork, and will suggest suitable cleaning schedules based upon your specific situation.
Check the Compressor
The compressor is a crucial component of the system. It needs to operate properly to provide cool air to the ducts. If the compressor isn’t functioning in the way it should and isn’t functioning properly, it could impact your productivity and result in equipment downtime. However, preventive maintenance can aid in identifying minor issues early and avoid excessive downtime. Conducting these regular checks can also help you save money by keeping your unit in good condition for as long as is possible.
A reduction in cooling capacity is a common sign of a problem in the compressor. It could be caused by several different factors. One possibility is that a compressor could be working too hard due to poor airflow. This can cause wear on the bearings and decrease the life of the compressor. Another issue that is common is a clogged filter. Filters that are clogged can reduce airflow and cause the compressor to overheat. To avoid this, it is essential to clean or replace the filters frequently, according to the manufacturer’s recommendation.
In addition, a clogged filter can also cause a rattling sound in the compressor. This could be a sign that the bearings need to be replaced. It is recommended to replace belts and pulleys on a regular basis. A loose belt or pulley can slip, causing the compressor to overheat, causing other issues. It’s also a good idea to drain your compressor on a regular basis. This will get rid of moisture that can cause corrosion to the motor and other components. A professional service team will also look for leaks in the hoses, as well as an adequate seal around the pressure sensor and compressor.
A puddle of water near the compressor can be a sign of a refrigerant leak. This could be a dangerous issue that needs to be addressed immediately. If you suspect a leak, shut off the air compressor. Consult a professional.
Check the Thermostat
It’s not too surprising that a technician will always examine the thermostat first if there is any issue. A properly maintained thermostat is vital to the smooth operation of your HVAC system. It’s among the most overlooked maintenance items. Common indicators that your thermostat is in need of periodic inspections include incorrect temperature readings, non-responsive controls, or constant cycling.
Inaccurate Temperature Readings
Over time, the thermostat’s sensors will get dirty. This could cause it to display inaccurately. Monitoring your thermostat’s accuracy regularly by using a separate thermometer can help you avoid these problems and help you save energy.
A faulty sensor or calibration may result in your system constantly turning on and off, which is referred to as short cycling. This can affect your comfort and cause excessive wear and tear on the compressor. This issue can be solved by replacing the batteries in the thermostat or resetting the breaker.
Make sure you check the breakers on both your HVAC and thermostat If your system isn’t responding to your thermostat. If the breaker has been tripped, it will require resetting in order for the thermostat to connect with the system once more.
It’s also important to check your thermostat for any signs of wear or damage. Examine for dust or dirt and ensure that the thermostat isn’t too much exposed to sunlight. Check the fan blades for evidence of damage or rust. These simple checks can prevent expensive repairs in the future, and ensure your equipment is operating as efficiently as it can.
Basic maintenance of hvac is a great way to reduce energy costs and keep your comfort in a commercial building. It can also prolong the lifespan of heating and cooling equipment. By identifying any issues with your thermostat, resetting the breaker and replacing the batteries and fuses, you’ll be able keep your building cool all year round. Be sure to call an expert if you’re having any other problems or unsure of what is wrong with your system.
