The Importance of HVAC Maintenance
Maintenance is essential when it concerns heating and cooling systems. It can help you avoid costly repairs or premature replacement. The majority of HVAC companies have a maintenance plan that charges a monthly fee to have the system inspected, repaired or cleaned as needed.
It’s also a good idea to perform some of the DIY maintenance tasks throughout the year. Cleaning or replacing air filters, and keeping the area around outdoor units clear of clutter will help ensure the proper airflow.
Clean the Condenser
The coils in your condenser for your air conditioner are at the heart the cooling process. If they’re dirty, your system will struggle to cool properly and may even break down. This is why cleaning them is a crucial aspect of HVAC maintenance. It’s also quite simple to do. This easy DIY task will save you money, avoid expensive repairs and extend the lifespan of your air cooling.
It is vital to cut off the power source from your unit first. This can be done by shutting off the breaker in the electrical box, or by turning off the outdoor unit disconnect switch. This will stop your motors and other electrical components from being oversaturated when cleaning.
When the power is turned off it is now time to remove any large debris obstructing the air condenser unit. This will include taking away any leaves, sticks or other debris that has built up on or around the unit. Utilizing a shop vacuum that has crevice attachments is a great method to get into the nooks and crannies and loosen any dust, dirt or other debris that has collected.
The coils must be cleaned. Be sure to have the necessary tools in your arsenal before you begin. This will include a coil cleaner concentrate, a pump-up garden sprayer and a garden hose. Spray the coil cleaner in accordance to the directions on the label, and then rinse with the hose. It is important not to use too much 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 or rocks thrown by lawnmowers and other things can harm the coil fins. Fin combs can be utilized to straighten bent fins to ensure improved airflow and coil performance.
If the fins and coils are in good shape, you can go back to your home and start your air conditioning. After around 24 hours, you should check the thermostat and ensure that the temperature is normal.
Cleaning the Ductwork
Your HVAC system is able to bring air from outside, cooling it and then distributing it throughout your home. The air is moved from the evaporator coil of your condenser unit and then to your home’s vents and registers through a system of ducts. These ducts may become clogged with dust and other pollutants when they aren’t cleaned and sealed properly. This can block the air filters and reduces the efficiency of the system and strains your AC unit.
In most instances, cleaning ductwork is not an easy job and requires expert equipment and methods. There are some things you can do regularly to keep your ducts clean and working well. To avoid dust and allergens from accumulating in the ducts, it is recommended to change your filter on a regular basis. This can also help stop clogging, which could cause a decrease in efficiency and higher energy costs.
Another way to keep your ducts clean is to regularly cleaning the area around the vent openings. Utilizing the hose attachment of your vacuum cleaner, you can get rid of all of the dust and crumbs that build up over time, and assist in improving airflow through the vent. It is also important to ensure that your ducts are sealed tightly and are insulated to prevent moisture from entering, which can lead to mold and other biological contaminants.
Ducts that have not been regularly cleaned are likely to be contaminated with a myriad of contaminants, such as dust, pet dander, and pollen. These particles can cause a flare-up of respiratory issues and allergies particularly in children and the elderly. Moisture can cause mold to grow in the ductwork, releasing microbes that can harm those suffering from respiratory ailments.
It is recommended that you clean your ducts every three to five years to remove these contaminants and ensure that your HVAC works efficiently. If your ducts are sealed well and you regularly change your filter It may not be necessary to clean them. The best way to determine 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 that are present in your ductwork. They will then recommend cleaning schedules that are suitable for your specific situation.
Check the Compressor
The compressor is an important element of the system. It must function properly to provide cool air to the ducts. If the compressor isn’t working as it should, it can affect your productivity and cause equipment downtime. Preventive maintenance can help spot minor issues earlier, avoiding unnecessary downtime. Regular checks can also save you money by making sure that your equipment as efficient as possible.
A typical sign of a compressor problem is a reduction in cooling capacity, however it could be caused by various factors. One possibility is that a compressor may be working too hard due to poor airflow. This could wear out the bearings and decrease the life of the compressor. Another issue that is common is a clogged filter. If the filter is clogged, it can reduce the airflow to the compressor and lead to overheating. It is crucial to clean or change the filters according to manufacturer’s guidelines.
In addition, a clogged filter can also cause a rattling sound in the compressor. This could be a sign that the bearings must be replaced. It is recommended to replace pulleys and belts on a regular basis. A pulley or belt that is loose can slip, causing the compressor to overheat, causing other problems. It is also a good idea to drain the compressor regularly. This will remove the accumulated moisture that can corrode the motor and other components. A professional service team can also examine for air leaks within the hoses and an adequate seal between the compressor and the pressure switch.
A puddle of liquid close to the compressor could be an indication of an issue. This is a potentially dangerous issue that needs to be addressed immediately. If you suspect that there is a leak, switch off the air compressor and call a professional.
Check the Thermostat
The thermostat is like the boss of your HVAC system, so it’s no surprise that it’s the first thing that a technician will inspect when a problem occurs. A properly maintained thermostat is vital to the smooth operation of your HVAC system. It’s one of the most neglected maintenance items. Check your thermostat if you observe 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. You can avoid this issue by ensuring the accuracy of your thermostat using a the use of a separate thermometer.
A defective sensor or a faulty calibration can cause your system to turn off and on continuously. This is called short cycling. This could have a negative effect on your comfort as well as cause unnecessary wear and tears on the compressor. Fortunately the majority of these issues can be fixed with the simple act of replacing the thermostat’s batteries or resetting its breakers.
Make sure you check the breakers on both your HVAC and thermostat if your system doesn’t respond to your thermostat. If the breaker tripped, you will need to reset it in order for your thermostat to be able to communicate with the system.
Check your thermostat for signs of wear and damage. Look for dust or dirt and make sure that the thermostat isn’t too much exposed to sunlight. Examine the fan blades for evidence of damage or rust. These simple checks can prevent costly repairs in the near future, and ensure your equipment is operating as smoothly as possible.
Conducting basic HVAC maintenance on your commercial property is a great way to reduce energy consumption, ensure comfort and prolong the life of your cooling and heating equipment. It is possible to keep your building at all times comfortable by identifying problems with your thermostat, resetting your breaker, and then replacing your batteries. Make sure to contact an expert if you’re experiencing any other issues or are unsure of what’s going on with your system.
