The Importance of HVAC Maintenance

Maintenance is essential when it concerns HVAC and cooling systems. It can help you avoid costly repairs or premature replacement. Most HVAC companies offer a service plan that allows you to pay a monthly fee to have the system inspected, repaired or cleaned as required.

It’s also recommended to do a few DIY maintenance tasks throughout the year. Cleaning or replacing air filters, and keeping the area around outdoor units free of clutter will help ensure the proper flow of air.

Clean the Condenser

The coils inside the condenser in your air conditioner are the mainstay of the cooling process. If they are dirty, you system will struggle to cool and could even breakdown. Cleaning them is an important component of HVAC maintenance. Fortunately, it is also relatively simple to complete. This easy DIY task can prevent the need for costly repairs, save you money on your energy bills, and extend the longevity of your AC unit.

In the beginning, it is crucial to shut off the power supply to your unit. You can do this 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 becoming oversaturated while cleaning.

After the power is off, you can begin removing any large objects that could be hindering the air condenser. This means sweeping off any sticks, leaves, or other debris that have built up around or on the unit. A shop vacuum that has crevice tools is a great way to get into the crevices, nooks, and loosen dust or dirt that has built up.

The coils need to be cleaned. Be sure to have a few essential tools available before you start. These include a concentrate for coil cleaning and a pump-up garden hose and a garden hose. Spray the coil cleaner according to the directions on the label, and then rinse it off using the water 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, inspect them for any signs of damage. Over time, the impact of hail and stones that are thrown by lawnmowers and other items can damage 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.

Once the coils and fins are in good condition, you can return to your house and turn on your air conditioning. After about 24 hours, you should check the thermostat to ensure that the temperatures are in line with normal.

Cleaning the Ductwork

Your HVAC system is able to bring air in from outside, cooling it, and then distributing it throughout your home. The air is transported from the evaporator of your condenser unit to your home’s registers and vents through a system duct. The ducts could become blocked with dust and other pollutants when they aren’t cleaned and sealed correctly. This causes air filters to become blocked, which in turn reduces the efficiency of the system and strains your AC unit.

Cleaning the ductwork is an extremely difficult job that requires professional equipment and methods. However, there are a few actions you can take regularly to make sure your ducts are in good condition and function properly. To prevent dust and allergens from building up in the ducts, you should change your filter frequently. This will also help prevent clogging, which can lead to a reduced system efficiency and a higher cost for energy.

Cleaning the area around the vent openings is an additional method to keep your ducts in good shape. By using the hose attachment on your vacuum cleaner, you can get rid of all the cobwebs and crumbs which accumulate over time, and assist in improving airflow through the vent. It’s also important to ensure that your ducts are sealed and sealed with insulation to keep out moisture, which can lead to mold and other biological contaminants.

If ducts aren’t cleaned regularly, they could accumulate a variety of contaminants such as dust, pet dander, and pollen. These particles can trigger respiratory issues and allergies, especially in children and the elderly. The moisture can cause mold to develop in ductwork, which releases microbes that can harm those suffering from respiratory ailments.

It is generally recommended to have your ducts cleaned every three to five years in order to eliminate these contaminants and ensure your HVAC system functions efficiently. However If your ducts are sealed and you clean your filters frequently the cleaning of your ducts may not be required at all. The best way to determine the truth is to have your ducts tested. A contractor accredited by the EPA can employ special testing methods in order to determine the amount of particulates found in your ductwork. They will then suggest cleaning schedules that are appropriate for your particular situation.

Check the Compressor

The compressor is a critical component of the system. It needs to operate properly to provide cool air to the ducts. If the compressor isn’t operating in the way it should, it can affect your productivity and cause the equipment to shut down. However, preventive maintenance can aid in identifying minor issues early and prevent unnecessary downtime. Performing these routine checks can also help you save money by keeping your unit in good condition for as long as possible.

A decrease in cooling capacity is a typical sign of a problem in a compressor. This can be caused by a variety of reasons. One possibility is that a compressor may be overworking because of poor airflow. This can wear out the bearings and diminish the life of the compressor. A clogged air filter is a different problem. If the filter is blocked it can impede airflow to the compressor, which can cause overheating. It is essential to clean or change the filters according to manufacturer’s instructions.

A clogged filter may also cause a sound of rattling in the compressor. This could mean that the bearings are worn out and need to be replaced. It is also a good idea to replace pulleys and belts regularly. A worn-out belt or pulley can cause the compressor to overheat and cause other issues. It’s also a good idea to drain your compressor frequently. This will get rid of the moisture that could cause corrosion to the motor and other components. A professional service team will also examine for air leaks within the hoses as well as a tight seal between the compressor and the pressure switch.

A small puddle of water around the compressor could be an indication of a leak in the refrigerant. This is a serious issue that needs to be addressed immediately. If you suspect that there is a leak, turn off the air compressor. Consult a professional.

Check the Thermostat

It’s not surprising that a technician will check the thermostat first when there is a problem. A properly maintained thermostat is essential for the efficient operation of your HVAC system. It’s among the most neglected maintenance items. Check your thermostat if you observe inaccurate temperature readings, unresponsive controls or constant cycling.

Inaccurate Temperature Readings

Thermostat sensors can become dirty over time, which may cause the device to display incorrectly. You can avoid these problems by regularly checking the accuracy of your thermostat with the use of a separate thermometer.

A malfunctioning sensor, or a faulty calibration can cause your system to cycle on and off continuously. This is referred to as short cycling. This can negatively impact your comfort and result in excessive wear and tear on the compressor. These issues can be resolved by simply replacing the thermostat’s batteries or resetting the breaker.

If your thermostat isn’t responding to your thermostat in any way, it’s an excellent idea to look at the breakers that control both the thermostat as well as your HVAC equipment. If the breaker has been tripped, it will have to be reset in order for the thermostat to communicate with the system.

Check your thermostat for indications of wear and damage. Examine for dust or dirt and make sure that the thermostat is not too much exposed to sunlight. Finally, the fan blades should be checked for indications of rust or damage. These simple checks can prevent costly repairs in the near future, and ensure your equipment is operating as efficiently as possible.

Basic hvac maintenance is a great strategy to save energy and maintain comfort in your commercial space. It also increases the lifespan 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 then replacing your batteries. Remember to call a professional if you are experiencing any other issues or unsure of what is wrong with your system.
