The Importance of HVAC Maintenance

When it comes to your heating and cooling system, maintenance is essential to avoid costly repairs or early-than-necessary replacement. The majority of HVAC companies offer a service plan that charges an affordable monthly fee to have your system checked, repaired or cleaned as required.

It’s also recommended to do some DIY maintenance tasks throughout the year. Cleaning or replacing air filters, and keeping the area surrounding outdoor units clear of any debris will ensure the proper airflow.

Clean the Condenser

The coils in the condenser of your air conditioner are the heart of the cooling process. If they’re dirty, your system will struggle to cool and may even breakdown. Cleaning them is an important component of HVAC maintenance. It’s fairly easy to complete. This simple DIY task will save you money, prevent costly repairs and prolong the lifespan of your air cooling.

In the beginning, it is important to disconnect the power supply to your unit. This can be done by turning off the breaker in your electrical box or by turning off the outdoor unit disconnect switch. This will stop your motors and other electrical components from getting overloaded during cleaning.

After the power has been shut off, you can begin to clear any large debris that is obstructing the air condenser unit. This includes cleaning off any sticks, leaves, or other debris that have built up on or around the unit. A shop vacuum that has a crevice tool is an excellent way to reach into the crevices, nooks and remove dust or dirt that has accumulated.

The coils must be cleaned. Make sure you have some essential tools available prior to beginning. Included in this are coil cleaning concentrates, a pump up garden sprayer and a garden hose. Spray the coil cleaner in accordance with the directions on the label, and then rinse with a hose. When washing the coils, it is important not to apply too much force since the fins can bend easily.

It is recommended to inspect the coils for signs of damage after cleaning. Over time, hail and rocks thrown from lawnmowers or other items can damage coil fins. Fin combs can be used to straighten bent fins to ensure better airflow and performance of the coil.

When you have a great coil and fin set up, you can start your air conditioner. After around 24 hours, you can examine the thermostat to ensure that temperatures are normal.

Clean the Ductwork

Your HVAC system works by bringing air in from outside, cooling it and distributing it throughout your home. The air moves from the evaporator coil of your condenser unit to the vents and registers of your home through a duct system. If these ducts aren’t cleaned and sealed, they can be laden with dust and other pollutants. This could block air filters, which decreases 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 expert equipment and techniques. There are some things you can do regularly to keep your ducts tidy and in good working order. First, change your filter regularly to prevent dust and allergens from building into the ducts. This also helps to keep the clogs from occurring which can cause a decrease in system efficiency and a high energy bill.

Another method to keep your ducts clean is by regularly vacuuming the area around the vent openings. The hose attachment of your vacuum cleaner will get rid of all the cobwebs, crumbs and other debris that have built up over time. This will increase airflow through the vent. It’s also important to ensure that your ducts are sealed and insulated to keep out moisture, which can lead to mold and other biological contaminants.

If ducts aren’t cleaned regularly, they can collect a variety of pollutants such as dust, pet dander, and pollen. These particles can worsen respiratory and allergy conditions especially in the elderly and children. Moisture in ductwork can also result in the growth of mold, which releases spores into air and poses health concerns for those who suffer from respiratory issues.

It is recommended that you clean your ductwork every three to five years to remove these contaminants and ensure that your HVAC system is functioning efficiently. However, if your ducts are well-sealed and you regularly change your filters the cleaning of your ducts may not be required at all. The best way to determine the truth is to have your ducts tested. An accredited contractor can use special testing methods to gauge the amount of dust particles in your ductwork and can recommend appropriate cleaning schedules that are based on the specific circumstances.

Check the Compressor

The compressor is an essential component of the system. It has to function properly to deliver cool air to the ducts. If the compressor isn’t functioning in the way it should and isn’t functioning properly, it could impact your productivity and cause the equipment to shut down. Preventive maintenance can help spot minor issues earlier, avoiding excessive downtime. Regular checks can also save you money by making sure that your equipment as efficient as possible.

A loss of cooling capacity is a common sign of a problem in the compressor. This can be caused by several different factors. A compressor may be operating too hard due to poor airflow. This could cause the bearings to wear out and reduce the lifespan of the compressor. A clogged 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 crucial to clean or change the filters regularly based on the manufacturer’s recommendations.

Additionally, a blocked filter may also cause rattling noises in the compressor. This could indicate that the bearings are wearing out and require to be replaced. It is recommended to replace belts and pulleys regularly. A loose pulley or belt could cause slipping and result in compressor overheating and other issues. It is recommended to drain the compressor regularly. This can remove accumulated moisture that can cause corrosion to the motor and other components. A professional service team will also look for leaks in the pipes, and ensure an adequate seal around the compressor and pressure sensor.

A puddle of liquid near the compressor could be a sign of leak. This is a risky problem that should 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 a surprise that a technician will always check the thermostat first when there’s any issue. A properly maintained thermostat is vital to the smooth operation of your HVAC system. It’s among the most frequently neglected maintenance items. Common signs that your thermostat is in need of periodic inspections include incorrect temperature readings, ineffective controls, or continuous cycling.

Inaccurate Temperature Readings

Over time the sensors on your thermostat can become dirty. This can cause it to display inaccurately. You can avoid these problems by ensuring the accuracy of your thermostat with a separate thermometer.

A malfunctioning sensor, or a faulty calibration can cause your system to turn off and on continuously. This is referred to as short cycling. This could have a negative effect on your comfort and result in excessive wear and tear on the compressor. Fortunately the majority of these issues can be fixed with simply replacing the batteries in your thermostat or resetting the breaker.

If your system isn’t responding to your thermostat at all it’s an excellent idea to look at the breakers that regulate the thermostat as well as your HVAC equipment. If the breaker has tripped, it’ll need to be reset in order for the thermostat to communicate with the system.

Check your thermostat for signs of wear and tear. Look for evidence of dust or dirt, and make sure the thermostat isn’t overly exposed to sunlight. Finally, the fan blades need to be examined for any signs of rust or damage. These simple checks can prevent costly repairs in the near future, and ensure your equipment is operating as smoothly as it is possible.

Performing basic hvac maintenance on your commercial building is an excellent method to cut energy consumption, ensure comfort and prolong the longevity of your heating and cooling equipment. By identifying problems with your thermostat, resetting the breaker, and replacing the batteries, you’ll be able to keep your building cool all year round. Just remember that should you encounter any other issues or aren’t sure the issue you should always consult a professional.
