The Importance of HVAC Maintenance
Maintenance is essential when it comes to heating and cooling systems. It will allow you to avoid costly repairs or premature replacement. The majority of HVAC companies offer a maintenance plan where you pay an affordable monthly fee to have your system checked, repaired or cleaned as required.
You should also perform some DIY maintenance throughout the year. Cleaning or replacing air filters, and keeping the area around outdoor units free of clutter will help ensure the proper airflow.
Clean the Condenser
The coils of the condenser of your air conditioner are the core of the cooling process. If they’re dirty, your system is likely to struggle to cool and could even fail. This is why cleaning them is a vital part of HVAC maintenance. It is, fortunately, fairly easy to do. This simple DIY task can prevent the need for expensive repairs, save you money on your energy bills, and extend the lifespan of your air conditioning unit.
In the beginning, it is essential to cut off the power source to your unit. This can be done by turning off the breaker inside your electrical box or at the outdoor unit disconnect switch. This will safeguard your electrical components and motors from being oversaturated when cleaning.
After the power has been shut off, you can begin removing any large debris that could be hindering the condenser air. This includes sweeping up any sticks, leaves or other debris that have accumulated on or around the unit. Using a shop vacuum with a crevice attachment is a great option to get into the crevices and nooks and get rid of dust, dirt or other debris that may have accumulated.
Next, it is time to clean the coils. Before you begin, though, make sure that you have in your possession a few key tools. Included in this are coil cleaning concentrates and a pump-up garden sprayer as well as an outdoor hose. Spray the coil cleaner according to the instructions on the label, and then rinse with a garden hose. When washing the coils, it is essential not to use excessive force since the fins can be bent easily.
After the coils have been cleaned, inspect them for any signs of damage. Over time, hail, rocks thrown by lawnmowers and other items can damage the coil fins. If the fins are bent, a low-cost tool known as a fin comb can straighten them for better air flow and also to aid in the operation of the coils more effectively.
After you have a proper coil and fin set up, you can start your air conditioner. After around 24 hours, you can check the thermostat and make sure that the temperature is normal.
Cleaning the Ductwork
Your HVAC system is able to bring air in from outside, cooling it and distributing it throughout the home. The air is moved from the evaporator coil inside your condenser unit to your house’s vents and registers through a system of ducts. These ducts may become clogged with dust and other pollutants when they aren’t maintained and sealed correctly. This can block the air filters, which in turn reduces the efficiency of your system and strains your AC unit.
In the majority of instances, cleaning ductwork isn’t an easy task and requires expert equipment and methods. There are a few things you can do regularly to keep your ducts tidy and functioning properly. First, make sure you change your filter regularly to prevent dust and allergens out of building into the ducts. This will also help prevent clogging, which can result in a decrease in system efficiency and higher energy costs.
Another way to help keep your ducts clean is by regularly cleaning the area around vent openings. Using the hose attachment on your vacuum cleaner, you can eliminate all the dust and crumbs that build up over time, and will help to improve airflow through the vent. Also, make sure that your ducts are sealed tight and protected from moisture getting in, which could cause mold and other biological contaminants.
If ducts aren’t cleaned regularly, they could accumulate a variety of contaminants like dust, pet dander and pollen. These particles can cause a flare-up of respiratory issues and allergies particularly for children and the elderly. In addition, moisture in ductwork may lead to the growth of mold which releases spores into the air and poses health concerns for those who suffer from respiratory problems.
It’s generally recommended that you get your ductwork cleaned every three to five years to remove these contaminates and ensure that your HVAC system is operating effectively. However it is possible that if your ducts are sealed properly and you clean your filters frequently, duct cleaning may not be necessary at all. The best way to know for certain is to have your ducts examined. A contractor that is certified by the EPA can employ specific testing methods to measure the amount particulates present in your ductwork. They will then suggest cleaning schedules that are appropriate for your situation.
Check the Compressor
The compressor is a crucial component of the system. It must be able to deliver cool air into the ducts. If the compressor isn’t working in the way it should, it can affect your productivity and cause equipment downtime. Regular maintenance can help you identify minor issues early, preventing excessive downtime. These routine checks will also save you money by ensuring that your equipment as efficient as possible.
A typical sign of a compressor issue is a reduction in cooling capacity, however it could be caused by various factors. A compressor may be working too hard due to inadequate airflow. This could wear out the bearings and diminish the life of the compressor. A blocked air filter is another frequent issue. If the filter is blocked it can impede airflow to the compressor and cause overheating. To avoid this, it is important to clean or change the filters frequently, according to the recommendations of the manufacturer.
Additionally, a blocked filter may also cause rattling noises in the compressor. This could indicate that the bearings need to be replaced. It is also a good idea to replace belts and pulleys regularly. A worn belt or pulley can cause slippage and cause compressor overheating and other issues. It is recommended to drain the compressor on a regular basis. This will eliminate the moisture that could cause corrosion to the motor and other components. A professional service team can also check for air leaks in the hoses and an adequate seal between the compressor and pressure switch.
A pool of water in the vicinity of the compressor could be a sign of a refrigerant leak. This is a serious issue that needs to be addressed immediately. If you suspect a leak, shut off the air compressor. Contact a professional.
Check the Thermostat
It’s not surprising that a technician will always look at the thermostat first when there is an issue. It’s also among the most frequently neglected maintenance items, yet maintaining your thermostat properly is essential to ensure your HVAC system’s proper operation. The most common signs that your thermostat is in need of a check-up include incorrect temperature readings, unresponsive controls, or continuous cycling.
Inaccurate Temperature Readings
Thermostat sensors can get dirty over time, which can cause the thermostat to display inaccurately. You can avoid this issue by checking the accuracy of your thermostat with an additional thermometer.
A faulty sensor, or a faulty calibration can cause your system to turn off and on in a continuous manner. This is known as short cycling. This could have a negative effect on your comfort as well as cause excessive wear and tear on the compressor. The problem can be fixed by replacing the thermostat’s batteries or resetting the breaker.
If your system isn’t responding to your thermostat in any way, it’s a good idea to check the breakers that control the thermostat as well as your HVAC equipment. If the breaker has tripped, it’ll require resetting in order for the thermostat to connect with the system once more.
It’s also crucial to examine your thermostat for any signs of wear or damage. Check for dirt or dust and make sure that the thermostat isn’t excessively exposed to the sun. Check the fan blades for signs of damage and rust. These simple checks can help avoid expensive repairs in the future, and help ensure that your equipment is operating as efficiently as possible.
Performing basic hvac maintenance on your commercial property is an excellent method to cut energy costs, maintain comfort and extend the longevity of your cooling and heating equipment. By identifying problems with your thermostat, setting the breaker, and replacing the batteries in the process, you’ll be able keep your building comfortable all year. Be sure to call a professional if you are having any other problems or unsure of what is the issue with your system.
