The Importance of HVAC Maintenance
Maintenance is crucial when it is concerned with HVAC and cooling systems. It will allow you to avoid costly repairs or premature replacement. Most HVAC companies have a maintenance plan where you pay each month to have your system checked, repaired or cleaned as required.
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 surrounding outdoor units free of debris will promote the proper flow of air.
Clean the Condenser
The coils in the condenser of your air conditioner are the core of the cooling process. If they are dirty your system will struggle to cool properly and could even fail. This is why cleaning them is a vital part of HVAC maintenance. Fortunately, it is also relatively simple to complete. This simple DIY task can avoid the need for expensive repairs, save you money on your energy bills, and prolong the longevity of your AC unit.
It is the first step. It is important to disconnect the power to your unit. This can be done by turning off the breaker in your electrical box or the outdoor unit disconnect switch. This will prevent your motors and other electrical components from being oversaturated during cleaning.
Once the power is off it is now time to clear any large debris blocking the air condenser unit. This means sweeping up any leaves, sticks, or other debris that has accumulated on or around the unit. A shop vacuum with crevice tools is a great way to get into the nooks and crannies, and loosen dust or dirt that has accumulated.
Next, it is time to clean the coils. Before you begin however, ensure that you have on-hand some essential tools. This will include a concentrate of the coil cleaner and a pump-up garden sprayer and a garden hose. Spray the coil cleaner on in accordance with the directions on the label of the product and then rinse using the hose. When washing the coils it is important not to apply too much force since the fins can bend easily.
After the coils have been cleaned, you should look them over for any indications of damage. Over time hail or stones thrown by lawnmowers, and other things can harm the coil fins. If the fins are bent, an affordable tool known as a fin comb can straighten them to improve air flow and also to assist in ensuring that the coils operate more effectively.
When the fins and coils are in good shape Once you’re satisfied with the condition of the fins and coils, you can go back to your home and switch on your air conditioner. After around 24 hours, you can examine the thermostat and ensure that the temperature is normal.
Clean the Ductwork
Your HVAC system works by bringing air in from outside, cooling it, and then distributing it throughout your home. The air is moved from the evaporator coil in your condenser unit to the vents and registers of your home through a duct system. These ducts can become clogged with dust and other contaminants when they aren’t cleaned and sealed correctly. This can block the air filters which can reduce the effectiveness of your system and can strain your AC unit.
In the majority of instances, cleaning ductwork isn’t an easy task that requires the help of professional equipment and techniques. However, there are a few things you can do on a regular basis to ensure your ducts stay clean and functioning well. To prevent dust and allergens accumulating in the ducts, change your filter on a regular basis. This will also help to prevent clogging, which can result in a decrease in system efficiency and a higher cost for energy.
Another method to keep your ducts clean is by regularly vacuuming the area around the vent openings. The hose attachment on your vacuum cleaner will remove all the cobwebs, crumbs and other debris that have accumulated over time. This will improve airflow through the vent. Also, make sure that your ducts have been sealed tightly and are lined to stop moisture from getting in, which could lead to 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 respiratory and allergy conditions particularly in the elderly and children. The moisture in ductwork can cause the growth of mold, which releases spores into air and poses health concerns for those who suffer from respiratory issues.
It is recommended to clean your ducts every three to five year to get rid of these toxins and ensure that your HVAC system is functioning efficiently. If your ducts have been well-sealed, and you regularly change your filter it might not be necessary to clean them. You can only be certain by having your ducts checked. A contractor who is accredited by the EPA will use special testing techniques to determine the amount of particulates found in your ductwork. They can then recommend cleaning schedules that are suitable for your situation.
Check the Compressor
The compressor is a critical element of the system. It has to be able to deliver cool air into the ducts. If the compressor isn’t working properly it could affect your productivity and cause equipment downtime. Preventive maintenance can help spot small issues early, preventing unnecessary downtime. Performing these routine checks can also help you save money by ensuring that your equipment is in good shape for as long as it is possible.
The most common sign of a compressor problem is a reduction in cooling capacity, however this could be caused by many different causes. One possibility is that the compressor may be under-performing due to inadequate airflow. This can wear out the bearings and decrease the lifespan of the compressor. Another issue that is common is a clogged filter. If the filter is clogged it could reduce the airflow to the compressor, which can cause overheating. It is essential to clean or change the filters according to manufacturer’s recommendations.
In addition, a clogged filter may also cause a rattling sound in the compressor. This could be an indication that the bearings require to be changed. Regularly replacing the belts and pulleys is recommended. A worn belt or pulley can cause slippage and cause overheating of the compressor and other issues. It is also a good idea to drain your 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 examine for leaks in hoses, as well as a tight seal on the compressor and pressure sensor.
A puddle of water near the compressor could be an indication of a leak in the refrigerant. This is a potentially dangerous problem that should be addressed immediately. If you suspect that there is a leak, turn off the air compressor and contact an expert.
Check the Thermostat
The thermostat is kind of like the boss of your entire HVAC system, and it’s not surprising that it’s the first thing a technician will check when trouble occurs. It’s also one of the most commonly overlooked maintenance items, but an appropriately maintained thermostat is crucial for ensuring your HVAC system’s proper operation. Common signs that your thermostat is in need of a check-up include incorrect temperature readings, non-responsive controls, or constant cycling.
Inaccurate Temperature Readings
Over time, the thermostat’s sensors may become dirty. This can cause it to display in a wrong manner. You can avoid these problems by regularly checking the accuracy of your thermostat using a an additional thermometer.
A malfunctioning sensor or calibration can also cause your system to keep switching off and on that is known as short cycling. This can adversely affect your comfort and cause unnecessary wear and tear on the compressor. Fortunately, these issues can often be fixed with the simple act of replacing the thermostat’s batteries or resetting the breaker.
Make sure you check the breakers on both your HVAC equipment and thermostat If your system isn’t responding to your thermostat. If the breaker has tripped it, you’ll need to reset it in order for your thermostat to reconnect with the system.
Check your thermostat for signs of wear and damage. Find indications of dust or dirt, and make sure the thermostat isn’t exposed to sunlight. Check the fan blades for signs of rust and damage. These simple checks will prevent costly repairs in the future and will ensure that your equipment operates as smoothly as it possibly can.
Conducting basic HVAC maintenance on your commercial property is a great way to reduce energy consumption, ensure comfort and extend the lifespan of your cooling and heating equipment. You can ensure that your building stays comfortable throughout the year by identifying problems with your thermostat, setting your breaker and replacing your batteries. Make sure to contact an expert if you’re having other issues or are unsure of what’s the issue with your system.
