The Importance of HVAC Maintenance

When it concerns your cooling and heating system, maintenance is the best way to avoid costly repairs or early-than-necessary replacement. Most HVAC companies offer a service plan that you pay the monthly cost to get the system checked, fixed or cleaned if necessary.

It is also recommended to perform DIY maintenance throughout the year. This includes cleaning or replacing air filters and keeping the space around outdoor units free of debris to promote the proper flow of air.

Clean the Condenser

The coils that make up your air conditioner’s condenser are the mainstay of the cooling process. If they’re dirty, your system will struggle to cool, and it could even breakdown. This is why cleaning them is an essential aspect of HVAC maintenance. Fortunately, it is also quite simple to do. This simple DIY task can prevent the need for costly repairs, save you money on your energy bills, and prolong the longevity of your AC unit.

It is essential to disconnect power from your unit first. This can be done by turning off the breaker on your electrical box, or the outdoor unit disconnect switch. This will safeguard your electrical components and motors from being oversaturated during cleaning.

After the power has been shut off it is now time to clear any large debris obstructing the air condenser unit. This includes taking away any sticks, leaves, or other debris that have accumulated on or around the unit. Using a shop vacuum with crevice attachments is a great method to get into the nooks and crevices and get rid of any dirt, dust or other debris that has accumulated.

The coils must be cleaned. Before you begin, though, make sure that you have on-hand a few key tools. Included in this are coil cleaning concentrates as well as a pump-up garden sprayer as well as a garden hose. Spray the coil cleaner in accordance with the instructions on the label, and then rinse it off using the water hose. It is crucial not to apply too much pressure when washing the coils, because the fins may be bent.

After the coils have been cleaned, inspect them for any indications of damage. Over time hail or rocks thrown by lawnmowers and other objects can cause damage to the coil fins. If the fins are bent, an affordable tool called a fin comb can straighten them to improve air flow and to help the coils function more efficiently.

When the fins and coils are in good condition If you are satisfied with the condition of your fins and coils, go back to your home and switch on your air conditioner. Check the thermostat after about 24 hours to make sure temperatures are normal.

Clean the Ductwork

Your HVAC system is able to bring air from outside into your home, cool it and then distribute it throughout your house. The air is transported from the evaporator of the condenser to your home’s registers and vents via a system duct. These ducts can become clogged with dust and other contaminants when they aren’t cleaned and sealed correctly. This causes air filters to become blocked which reduces the efficiency of your system and puts strain on your AC unit.

In the majority of instances, cleaning ductwork isn’t an easy job and requires expert equipment and techniques. There are a few things you can do to keep your ducts clean and working well. First, you should change your filter on a regular basis to prevent dust and allergens from building in the ducts. This will also help to keep clogs from occurring, which could result in a decrease in system efficiency and higher energy costs.

Another way to help keep your ducts clean is by regularly vacuuming the area around the vent openings. The hose attachment on your vacuum cleaner will take away all traces of dust, crumbs and other messes that have accumulated over time. This will increase the flow of air through the vent. It is also important to make sure your ducts are sealed and insulated to keep out moisture which can cause mold and other biological contaminants.

Ducts that aren’t cleaned on a regular basis can be filled with a variety of contaminants, such as dust, pet dander and pollen. These particles can worsen 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 can cause health issues for those suffering from respiratory problems.

It is recommended that you clean your ductwork every three to five year to eliminate these contaminates and ensure that your HVAC is operating efficiently. However, if your ducts are sealed properly and you regularly change your filters the cleaning of your ducts may not be required at all. The best way to know for certain is to have your ducts examined. A contractor who is accredited by the EPA can use special testing techniques to determine the amount of particulates that are present in your ductwork. They will then suggest cleaning schedules that are appropriate 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 as it should, this could affect the efficiency of your business and lead to delays for your equipment. However, preventive maintenance can assist in identifying issues that are minor and prevent unnecessary downtime. These routine checks will also save you money by making sure that your equipment in the best condition possible.

A decrease in cooling capacity is a typical sign of a problem with a 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 the bearings to wear down and decrease the life of the compressor. A blocked air filter is a different problem. Filters that are clogged can hinder airflow and cause the compressor to overheat. To avoid this, it is crucial to clean or change the filters frequently, according to the manufacturer’s recommendation.

A blocked filter could cause a sound of rattling in the compressor. This could be an indication that the bearings must be changed. It is also a good idea to replace pulleys and belts regularly. A worn-out belt or pulley can slip, causing the compressor to overheat, causing other problems. It is also a great idea to drain your compressor regularly. This will get rid of moisture that can cause corrosion to the motor and other components. A professional service team can also check for air leaks in the hoses, and ensure an adequate seal between the compressor and pressure switch.

A small puddle of water around the compressor could be an indication of a refrigerant leak. This could be a risky issue that needs to be addressed right away. If you suspect there is a leak, switch off the air compressor and contact an expert.

Check the Thermostat

The thermostat is like the boss of your entire HVAC system, so it’s not surprising that it’s the first thing that a technician will inspect when a problem arises. It’s also one of the most often neglected maintenance items, yet maintaining your thermostat properly is vital to ensure your HVAC system’s operation. Examine your thermostat if you notice incorrect temperature readings, ineffective controls or constant cycling.

Inaccurate Temperature Readings

Thermostat sensors can get dirty over time, which may cause the thermostat to display inaccurately. You can prevent these issues by regularly checking the accuracy of your thermostat with the use of a separate thermometer.

A malfunctioning sensor, or a wrong calibration, could cause your system to cycle on and off in a continuous manner. This is referred to as short cycling. This could have a negative effect on your comfort and cause unnecessary wear and tears on the compressor. The problem can be fixed by simply replacing the batteries in the thermostat or resetting the breaker.

Make sure you check the breakers on both your HVAC and thermostat if your system doesn’t respond to your thermostat. If the breaker has tripped, it’ll need to be reset to allow the thermostat to connect with the system once more.

It is also essential to examine your thermostat for signs of wear or damage. Examine for dust or dirt and ensure that the thermostat isn’t excessively exposed to the sun. Lastly, the fan blades should be checked for indications of rust or damage. These simple checks will prevent costly repairs in the future, and ensure that your equipment is running as smoothly as it can.

Conducting basic HVAC maintenance on your commercial building is an excellent way to cut down on energy consumption, ensure comfort and extend the lifespan of your heating and cooling equipment. By identifying problems with your thermostat, resetting the breaker, and then replacing the batteries, you’ll be able to keep your building warm all year round. Be sure to call a professional if you have any other issues or are unsure about what’s wrong with your system, always call in a professional.
