The Importance of HVAC Maintenance

When it comes to your cooling and heating system, maintenance is essential to avoid costly repairs or early-than-necessary replacement. Most HVAC companies offer a service plan that charges an affordable monthly fee to get the system checked, repaired or cleaned when necessary.

It is also recommended to perform DIY maintenance throughout the year. These include cleaning or replacing air filters and keeping the space around outdoor units free of any debris to ensure proper airflow.

Clean the Condenser

The coils in the condenser of your air conditioner are at the heart the cooling process. If they’re dirty, your system will struggle to cool and could even breakdown. Cleaning them is a crucial aspect of HVAC maintenance. It is, fortunately, fairly easy to do. This simple DIY task will help you save money, avoid costly repairs, and increase the lifespan of your air conditioner.

In the beginning, it is important to disconnect the power to your unit. This can be done by shutting off the breaker in your electrical box or by turning off the outdoor unit disconnect switch. This will prevent your motors and other electrical components from being oversaturated while cleaning.

After the power has been turned off, you can begin clearing any large objects that could be hindering the air condenser. This includes sweeping up any leaves, sticks, or other debris that have been accumulating on or around the unit. A shop vacuum that has crevice tools is a great tool to reach into the crevices, nooks and remove dust or dirt that has accumulated.

The coils need to be cleaned. Before you do this however, ensure you have a few key tools. This will include a concentrate for coil cleaning and a pump-up garden sprayer and a garden hose. Spray the coil cleaner according to the instructions on the label of the product and then rinse it off using the hose. It is crucial not to apply too much 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, stones thrown by lawnmowers, and other things can harm the coil fins. Fin combs can be used to straighten bent fins to ensure improved airflow and coil performance.

Once you have a good coil and fin set up then you can start your air conditioner. After approximately 24 hours, you can examine the thermostat and ensure that the temperature is normal.

Clean the Ductwork

Your HVAC system works by bringing air from outside, cooling it and distributing it throughout the home. The air travels from the evaporator coil in your condenser unit to the vents and registers of your home through a duct system. If these ducts aren’t properly cleaned and sealed, they can become clogged with dust and other pollutants. This can block the air filters and reduces the efficiency of the system and puts strain on your AC unit.

Cleaning ductwork can be a difficult task that requires expert equipment and techniques. However, there are a few things you can do regularly to ensure that your ducts are in good condition and function properly. To avoid dust and allergens from accumulating in the ducts, you should change your filter frequently. This can also help keep clogs from occurring, which could lead to a reduced system efficiency and higher energy costs.

Another way to help keep your ducts clean is by regularly cleaning the area around the vent openings. Using the hose attachment on your vacuum cleaner, you can eliminate all the cobwebs and crumbs that accumulate over time, and help to improve air flow through the vent. Also, make sure that your ducts have been sealed well and are protected from moisture entering, which can result in mold and other biological contaminants.

Ducts that aren’t cleaned on a regular basis are likely to be contaminated with a myriad of pollutants, including dust, pet dander and pollen. These particles can exacerbate respiratory issues and allergies, especially for older people and children. The moisture can cause mold to grow in ductwork, which releases microbes that can harm those suffering from respiratory ailments.

It’s generally recommended that you get your ductwork cleaned every three to five years in order to eliminate these contaminants and ensure your HVAC system is operating effectively. However it is possible that if your ducts are sealed properly and you change your filters regularly it is possible that duct cleaning won’t be necessary at all. You can be certain by having your ducts checked. A licensed contractor can employ special testing methods to gauge the amount of dust particles within your ductwork, and will recommend the appropriate cleaning schedules based on the specific circumstances.

Check the Compressor

The compressor is a critical element of the system. It has to be able to deliver cool air into the ducts. If the compressor isn’t operating properly, it can affect your productivity and cause interruption to your equipment. Regular maintenance can help you identify small issues early, preventing excessive downtime. Regularly checking your unit can also save you money by keeping your unit in good shape for as long as it is possible.

A reduction in cooling capacity is a common sign of a problem in a compressor. This can be caused by several different causes. One possibility is that the compressor may be under-performing due to inadequate airflow. This can cause wear on the bearings and decrease the lifespan of the compressor. Another common problem is a blocked filter. Filters that are clogged can restrict airflow and cause the compressor to overheat. It is crucial to clean or change the filters according to the manufacturer’s instructions.

A blocked filter can cause a rattling sound in the compressor. This could indicate that the bearings are worn out and require to be replaced. It is recommended to replace pulleys and belts regularly. A loose belt or pulley could cause the compressor to overheat and cause other issues. It is also a good idea to drain the compressor on a regular basis. This will help remove moisture that can corrode the motor and other components. A professional service team can also look for air leaks in the hoses, and ensure a tight seal between the compressor and pressure switch.

A puddle of liquid near the compressor could be an indicator of a leak. This could be a dangerous problem that should be addressed immediately. If you suspect that there is a leak, turn off the air compressor and call a professional.

Check the Thermostat

It’s not surprising that technicians will always look at the thermostat first when there’s an issue. It’s also one of the most often neglected maintenance items, but an appropriately maintained thermostat is crucial for ensuring your HVAC system’s operation. Common indicators that your thermostat requires a check-up include incorrect temperature readings, ineffective controls, or constant cycling.

Inaccurate Temperature Readings

Over time, the thermostat’s sensors may get dirty. This could cause it to display in a wrong manner. Monitoring your thermostat’s accuracy regularly with a separate thermometer will aid in avoiding these issues and help you save energy.

A malfunctioning sensor or calibration can also result in your system constantly switching off and on that is known as short cycling. This can negatively impact your comfort and cause excessive wear and tear on the compressor. Fortunately the majority of these issues can be resolved with simply replacing the batteries in your thermostat or resetting the breaker.

Make sure you check the breakers on both your HVAC equipment and thermostat in the event that your HVAC equipment doesn’t respond to your thermostat. If the breaker has tripped, it will need to be reset to allow the thermostat to be able to communicate with the system.

Check your thermostat for indications of wear and tear. Find indications of dust or dirt and ensure that the thermostat isn’t exposed to sunlight. The fan blades must be inspected for any indications of rust or damage. These simple checks can help avoid costly repairs in the near future, and help ensure that your equipment is running as smoothly as it can.

Basic maintenance of hvac is a great method to save energy and keep your comfort in a commercial space. It can also prolong the lifespan of cooling and heating equipment. You can keep your building at all times comfortable by identifying issues with your thermostat, resetting your breaker and changing your batteries. Just remember that should you encounter any other issues or aren’t sure what’s wrong with your system, always call in an expert.
