The Importance of HVAC Maintenance

When it concerns your cooling and heating system, regular maintenance is the key to avoiding costly repairs or replacements that are not needed as soon as they should be. The majority of HVAC companies have a maintenance plan where you pay each month to have the system inspected and cleaned, or repaired as needed.

You should also perform some DIY maintenance throughout the year. Cleaning or replacing air filters and keeping the area surrounding outdoor units free of debris will promote the proper airflow.

Clean the Condenser

The coils in the condenser of your air conditioner are the mainstay of the cooling process. If they are dirty, your system will struggle to cool and could even fail. This is why cleaning them is a crucial component of HVAC maintenance. It is relatively easy to complete. This simple DIY task will eliminate the need for expensive repairs, save you money on your energy bills and extend the lifespan of your air conditioning unit.

It is crucial to disconnect power from your unit before you disconnect it. You can do this by turning off the breaker on your electrical box or by turning off the outdoor unit disconnect switch. This will stop your motors and other electrical components from becoming oversaturated while cleaning.

Once the power has been shut off, you can begin taking down any large debris that could be blocking the condenser air. This means sweeping up any sticks, leaves, or other debris that has been accumulating around or on the unit. A shop vacuum equipped with a crevice attachment is a great option to reach into the nooks and crannies and loosen dust, dirt or other debris that has collected.

The coils must be cleaned. Be sure to have a few essential tools in your arsenal before you begin. Included in this are a coil cleaning concentrate and a pump-up garden sprayer and the garden hose. Spray the coil cleaner in accordance to the instructions on the label, then rinse it off with the garden hose. When washing the coils, it is essential not to use excessive force since the fins are easily bent.

After the coils have been cleaned, look them over for any signs of damage. Over time hail, stones thrown by lawnmowers, and other things can harm the coil fins. If the fins are bent, a cost-effective tool known as a fin comb can straighten them to improve air flow and aid in the operation of the coils more effectively.

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 switch on your air conditioner. After approximately 24 hours, you can check the thermostat to ensure that the temperatures are in line with normal.

Cleaning the Ductwork

Your HVAC system is designed to bring air from outside into your home, cool it, and then distribute it throughout your house. The air travels from the evaporator coil of your condenser unit to your home’s vents and registers through a system of ducts. The ducts could become blocked with dust and other pollutants when they aren’t maintained and sealed properly. This causes air filters to become blocked which reduces the efficiency of the system and puts strain on your AC unit.

Cleaning the ductwork can be an extremely difficult job that requires expert equipment and techniques. There are a few things you can do to ensure that your ducts are clean and in good working order. To avoid dust and allergens from building up in the ducts, it is recommended to change your filter on a regular basis. This will also help to keep clogs from occurring, which could cause a decrease in efficiency and a higher cost for energy.

Another way to keep your ducts clean is by regularly cleaning the area around vent openings. By using the hose attachment on your vacuum cleaner, you can get rid of all of the cobwebs and crumbs which accumulate over time, and help to improve air flow through the vent. It is also important to ensure that your ducts are sealed tightly and are lined to stop moisture from getting in, which could lead to mold and other biological contaminants.

Ducts that are not cleaned on a regular basis are likely to be contaminated with a variety of contaminants, such as dust, pet dander and pollen. These particles can trigger allergies and respiratory conditions particularly for older people and children. Moisture can cause mold to develop in the ductwork, which releases the spores that can be harmful to people suffering from respiratory issues.

It is generally recommended to get your ductwork cleaned every three to five years in order to eliminate the toxins and ensure that your HVAC system is working effectively. However, if your ducts are sealed properly and you clean your filters frequently, duct cleaning may not be required at all. The best way to be able to tell the truth is to have your ducts examined. A certified contractor can employ special testing methods to gauge the amount of particles in your ductwork and will recommend the suitable cleaning schedules based upon your particular situation.

Check the Compressor

The compressor is a crucial element of the system. It must be able to supply cool air into the ducts. If the compressor isn’t functioning as it should, this can affect the efficiency of your business and lead to interruption to your equipment. Preventive maintenance can help identify small issues early, preventing unnecessary downtime. Performing these routine checks can also save you money by keeping your unit in good shape for as long as is possible.

The most common sign of a compressor issue is a decrease in cooling capacity, but this could be caused by various factors. A compressor could be working too hard due to inadequate airflow. This could wear out the bearings and reduce the lifespan of the compressor. Another issue that is common is a clogged filter. If the filter is blocked it could reduce the airflow to the compressor and lead to overheating. To avoid this, it is essential to clean or change the filters on a regular basis, based on the recommendations of the manufacturer.

A clogged filter may also cause a rattling sound in the compressor. This could mean that the bearings are worn out and require to be replaced. Regularly replacing pulleys and belts is a good idea. A worn-out belt or pulley can slip, causing the compressor to overheat and create other problems. It is also a great idea to drain your compressor regularly. This will remove moisture that can cause corrosion to the motor and other components. A professional service team can also look for air leaks in the hoses, and ensure an adequate seal between the compressor and pressure switch.

Finally, a pool of water in the vicinity of the compressor can be a sign of a leak in the refrigerant. This could be a dangerous problem that should be addressed immediately. If you suspect a leak, shut off the air compressor. Contact a professional.

Check the Thermostat

It’s not a surprise that a technician will examine the thermostat first if there is a problem. It’s also among the most commonly overlooked maintenance items, yet an appropriately maintained thermostat is vital to ensure your HVAC system’s operation. Check your thermostat if observe inaccurate temperature readings, unresponsive controls, or continuous cycling.

Inaccurate Temperature Readings

Over time, the thermostat’s sensors may get dirty. This can cause it to display inaccurately. You can prevent these issues by regularly checking the accuracy of your thermostat by using a a separate thermometer.

A faulty sensor or calibration could cause your system to keep switching on and off, which is referred to as short cycling. This can have a negative impact on your comfort as well as cause unnecessary wear and tears on the compressor. Fortunately the majority of these issues can be fixed with simply replacing the thermostat’s batteries or resetting the breaker.

If your thermostat isn’t responding to your thermostat at all, it’s a good idea to check the breakers that control both the thermostat and your HVAC equipment. If the breaker tripped, you will need to reset it to allow your thermostat to communicate again with the system.

Check your thermostat for indications of wear and tear. Look for signs of dirt or dust, and make sure the thermostat isn’t exposed to sunlight. Examine the fan blades to find signs of damage and rust. These simple checks will prevent costly repairs in the future and will ensure that your equipment runs as smoothly as possible.

The simple maintenance of hvac systems on your commercial property is an excellent method to cut energy costs, maintain comfort and extend the life of your cooling and heating equipment. You can keep your building cool throughout the year by identifying any issues with your thermostat, setting your breaker and changing your batteries. Just remember that in case you experience any other issues or are unsure about what’s wrong with your system make sure to contact an expert.
