The Importance of HVAC Maintenance

When it comes to your heating and cooling system, routine maintenance is essential to avoid costly repairs or premature replacement. The majority of HVAC companies offer a service plan that charges an affordable monthly fee to have the system checked, fixed or cleaned when needed.

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 debris to promote proper airflow.

Clean the Condenser

The coils of the condenser of your air conditioner are the primary component of the cooling process. If they are dirty, your system is likely to struggle to cool and may even fail to function properly. Cleaning them is a crucial component of HVAC maintenance. It is, fortunately, relatively simple to complete. This easy DIY task will eliminate the need for costly repairs, save you money on your energy bills and prolong the lifespan of your air conditioning unit.

In the beginning, it is essential to cut off the power supply to your unit. You can do this by turning off the breaker in your electrical box or by turning off the outdoor unit disconnect switch. This will protect your electrical components and motors from being oversaturated during cleaning.

Once the power is off and you are able to clean up any large debris that is blocking the air condenser unit. This includes cleaning up any sticks, leaves, or other debris that have built up around or on the unit. Using a shop vacuum with a crevice attachment is a great method to get into the crevices and nooks and get rid of any dust, dirt or other debris that may have accumulated.

The coils need to be cleaned. Be sure to have a few essential tools on hand prior to beginning. Included in this are a coil cleaning concentrate, a pump up garden sprayer as well as the garden hose. Spray the coil cleaner on according to the directions on the label of the product and rinse with the hose. It is crucial not to apply too much pressure when washing the coils since the fins could easily be bent.

It is recommended to inspect the coils for signs of damage after cleaning. Over time hail and rocks thrown by lawnmowers and other items can damage the coil’s fins. Fin combs are a great way to straighten bent fins to ensure better airflow and performance of the coil.

After you have a proper coil and fin set up and you are ready to turn 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 able to bring air in from outside, cooling it and distributing it throughout your home. Air is moved from the evaporator inside the condenser to your home’s registers and vents via the system of ducts. The ducts could become blocked with dust and other pollutants when they aren’t maintained and sealed properly. This can block the air filters and reduces the efficiency of the system and puts strain on your AC unit.

Cleaning the ductwork is a challenging task that requires expert equipment and methods. However, there are some things you can do regularly to ensure that your ducts stay in good condition and function properly. First, make sure you change your filter on a regular basis to keep dust and allergens from building into the ducts. This will also help to keep clogs from occurring, which could lead to a reduced system efficiency and higher energy costs.

Another way to keep your ducts clean is to regularly cleaning the area around vent openings. The hose attachment on your vacuum cleaner will get rid of all the cobwebs, crumbs and other debris that has built up over time. This will increase the flow of air through the vent. It’s also important to make sure your ducts are properly sealed and sealed with insulation to keep out moisture which can lead to mold and other biological contaminants.

Ducts that have not been 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 cause a flare-up of allergies and respiratory conditions particularly for older people and children. Moisture can cause mold to develop in ductwork, which releases the spores that can be harmful to people suffering from respiratory issues.

It is recommended to clean your ducts once every three to five year to eliminate these contaminates and ensure that your HVAC system is functioning efficiently. However If your ducts are sealed properly and you change your filters regularly, duct cleaning may not be necessary at all. You can only be sure by having your ducts checked. A contractor that is certified by the EPA can employ special testing methods in order to determine the amount of particles that are present in your ductwork. They will then suggest cleaning schedules that are suitable for your specific situation.

Check the Compressor

The compressor is a crucial element of the system. It must be able to provide cool air to the ducts. If the compressor isn’t operating in the way it should, this can impact your productivity and cause delays for your equipment. Preventive maintenance can help spot minor issues early, preventing unnecessary downtime. Regularly checking your unit can also save you money by keeping your unit in good working order for as long as possible.

The most common sign of a compressor problem is a reduction in cooling capacity, but this could be caused by many different causes. A compressor could be working too hard due to poor airflow. This can wear out the bearings and decrease the life of the compressor. Another issue that is common is a blocked filter. If the filter is blocked, it can reduce the airflow to the compressor and lead to overheating. It is crucial to clean or change the filters according to the manufacturer’s recommendations.

A blocked filter could cause rattling sounds in the compressor. This could mean that the bearings are wearing out and need to be replaced. It is also a good idea to replace belts and pulleys regularly. A pulley or belt that is loose could cause the compressor to overheat and create other issues. It is also a good idea to drain your compressor frequently. This will remove the accumulated moisture that can cause corrosion to the motor and other components. A professional service team can look for air leaks in the hoses, and ensure a tight seal between the compressor and the pressure switch.

Lastly, a small puddle of water around the compressor could be an indication of a refrigerant leak. This could be a dangerous problem that must be dealt with immediately. If you suspect that there is a leak, turn off the air compressor and contact a professional.

Check the Thermostat

It’s not surprising that a technician will always look at the thermostat first when there is a problem. A properly maintained thermostat is crucial to the smooth operation of your HVAC system. It’s among the most neglected maintenance items. Common indicators that your thermostat needs periodic inspections include incorrect temperature readings, unresponsive controls, or continuous cycling.

Inaccurate Temperature Readings

Over time the thermostat’s sensors may become dirty. This can cause it to display inaccurately. Regularly checking your thermostat’s accuracy with a separate thermometer will help you avoid these problems and conserve energy.

A defective sensor or a wrong calibration, could cause your system to turn off and on constantly. This is called short cycling. This can adversely affect your comfort and cause unnecessary wear and tear on the compressor. This issue can be solved by replacing the batteries in the thermostat or resetting the breaker.

If your system isn’t responding to your thermostat at all, it’s recommended to examine the breakers that control the thermostat and your HVAC equipment. If the breaker has been tripped, it will have to be reset to allow the thermostat to connect with the system again.

It’s also important to check your thermostat for any signs of wear or damage. Check for signs of dirt or dust and ensure that the thermostat isn’t 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 future and ensure that your equipment operates as smoothly as it can.

Basic HVAC maintenance is a great method to reduce energy costs and maintain comfort in your commercial space. It also increases the lifespan of cooling and heating equipment. By identifying problems with your thermostat, setting the breaker and replacing the batteries in the process, you’ll be able keep your building comfortable all year round. Just remember that should you encounter any other issues, or are unsure about the issue, always call in an expert.
