The Importance of HVAC Maintenance

Maintenance is crucial when it concerns cooling and heating systems. It will allow you to avoid costly repairs or premature replacement. The majority of HVAC companies have a service plan that allows you to pay a monthly fee to have the system checked and cleaned or repaired when needed.

You should also carry out some DIY maintenance throughout the year. Cleaning or replacing air filters, and keeping the area surrounding outdoor units free of any debris will ensure the proper airflow.

Clean the Condenser

The coils that make up the condenser of your air conditioner are the mainstay of the cooling process. If they are dirty, your system will struggle to cool properly and may even fail to function properly. This is why cleaning them is a vital component of HVAC maintenance. It is relatively easy to do. This simple DIY task will save you money, avoid costly repairs, and increase the life of your air cooling.

It is the first step. It is important to disconnect the power supply to your unit. This can be accomplished by shutting off the breaker inside your electrical box or by turning off the outdoor unit disconnect switch. This will stop your motors and other electrical components from becoming oversaturated during cleaning.

When the power is turned off it is now time to clear any large debris that is obstructing the air condenser unit. This means sweeping up any leaves, sticks, or other debris that have built up around or on the unit. Utilizing a shop vacuum that has crevice attachments is a great option to reach into the nooks and crevices and remove dust, dirt or other debris that has collected.

The next step is to clean the coils. Before doing this however, ensure that you have in your possession some essential tools. This will include a coil cleaner concentrate, a pump-up garden sprayer and a garden hose. Spray the coil cleaner on according to the instructions on the product’s label and rinse with the hose. It is essential not to apply excessive pressure when washing the coils, since the fins could easily be bent.

You should examine the coils for signs of damage after cleaning. Over time, hail, rocks thrown by lawnmowers and other things can harm the coil fins. Fin combs can be utilized to straighten bent fins for better airflow and performance of the coil.

If the fins and coils are in good shape, you can return to your house and turn on your air conditioner. After about 24 hours, you can check the thermostat and ensure that the temperature is normal.

Clean the Ductwork

Your HVAC system is able to bring air from outside, cooling it and then distributing it throughout your home. The air travels from the evaporator coil in the condenser unit to your house’s vents and registers through a network of ducts. These ducts may become clogged with dust and other contaminants if they are not cleaned and sealed correctly. This clogs the air filters which reduces the efficiency of your system and strains your AC unit.

In the majority of instances, cleaning ductwork isn’t an easy task that requires professional equipment and techniques. But, there are things you can do on a regular basis to ensure your ducts stay clean and well-functioning. First, make sure you change your filter regularly to keep dust and allergens out of building into the ducts. This will also help stop clogging, which could result in a decrease in system efficiency and higher energy bills.

Vacuuming the area surrounding the vent openings is another method to keep your ducts clean. The hose attachment on your vacuum cleaner will get rid of all the cobwebs, crumbs and other debris that have accumulated over time. This will increase airflow through the vent. Also, make sure that your ducts are sealed tightly and are insulated to prevent moisture from getting in, which could result in mold and other biological contaminants.

If ducts are not cleaned regularly, they could accumulate a variety of contaminants such as dust, pet dander, and pollen. These particles can exacerbate respiratory and allergy conditions especially for children and the elderly. The moisture in ductwork can result in the growth of mold which releases spores into the air and poses health concerns for those suffering from respiratory problems.

It’s generally recommended that you get your ductwork cleaned every three to five years to eliminate these contaminates and ensure that your HVAC system is operating effectively. If your ducts have been sealed properly, and you change your filter regularly it might not be necessary to clean them. The best way to determine the truth is to have your ducts tested. A contractor who is accredited by the EPA will use special testing techniques to measure the amount particulates present in your ductwork. They can then recommend cleaning schedules that are suitable for your particular situation.

Check the Compressor

The compressor is an essential component of the system. It should be able provide cool air to the ducts. If the compressor isn’t functioning properly, it could affect the efficiency of your business and lead to downtime for equipment. Regular maintenance can help you identify small issues early, preventing unnecessary downtime. Performing these routine checks can also save you money by keeping your unit in good working order for as long as it is possible.

A loss of cooling capacity is a typical indication of a problem with the compressor. This could be caused by several different factors. One possibility is that a compressor may be working too hard due to poor airflow. This could cause bearings to wear out and reduce the lifespan of the compressor. Another common problem is a clogged filter. If the filter is blocked it can impede airflow to the compressor and cause overheating. It is essential to change or clean the filters according to the manufacturer’s instructions.

A blocked filter may also cause rattling noises in the compressor. This could indicate that the bearings are wearing out and need to be replaced. It is recommended to replace pulleys and belts on a regular basis. A loose pulley or belt can cause slippage and cause overheating of the compressor and other issues. It is recommended to drain the compressor regularly. This will get rid of moisture that can cause corrosion to the motor and other parts. A professional service team can check for air leaks in the hoses, and ensure an adequate seal between the compressor and the pressure switch.

Lastly, a small puddle of water around the compressor can be an indication of a refrigerant leak. This can be a dangerous issue and should be repaired right away. If you suspect a leak, turn off the air compressor. Consult a professional.

Check the Thermostat

It’s not surprising that a technician will examine the thermostat first if there’s an issue. A properly maintained thermostat is essential for the smooth operation of your HVAC system. It’s among the most overlooked maintenance items. Check your thermostat if you find inaccurate temperature readings, ineffective controls, or constant cycling.

Inaccurate Temperature Readings

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

A malfunctioning sensor or calibration may cause your system to keep switching on and off this is known as short cycling. This can adversely affect your comfort, and cause excessive wear and tear on the compressor. This issue can be solved by simply replacing the batteries in the thermostat or resetting the breaker.

If your thermostat isn’t responding to your thermostat at all, it’s an excellent idea to look at 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 be able to communicate with the system.

Examine your thermostat for signs of wear and damage. Check for evidence of dust or dirt, and make sure the thermostat isn’t too exposed to sunlight. The fan blades should be checked for signs of damage or rust. These simple checks can prevent costly repairs in the future, and help ensure that your equipment is running as smoothly as it is possible.

Basic HVAC maintenance is a great method to save energy and keep your comfort in a commercial building. It will also extend the lifespan of cooling and heating equipment. By identifying any issues with your thermostat, setting the breaker, and then replacing the batteries, you’ll be able to keep your building warm all year round. Just remember that in case you experience any other issues or aren’t sure the issue, always call in an expert.
