The Importance of HVAC Maintenance

Maintenance is key when it comes to HVAC and cooling systems. It will help you avoid costly repairs or premature replacement. Most HVAC companies offer a service plan where you pay a monthly fee to have the system inspected and cleaned or repaired when required.

You should also carry out some DIY maintenance throughout the year. These include cleaning or replacing air filters, and keeping the area around outdoor units free of debris to promote proper airflow.

Clean the Condenser

The coils of your air conditioner condenser are the primary component of the cooling process. If they are dirty, your system will struggle to cool and could even fail. Cleaning them is an essential component of HVAC maintenance. It’s relatively simple to accomplish. This simple DIY task can avoid the need for costly repairs, save you money on your energy bills, and extend the life of your air conditioning unit.

In the beginning, it is important to disconnect the power source to your unit. This can be accomplished by shutting off the breaker inside the electrical box, or by turning off the outdoor unit disconnect switch. This will stop your motors and other electrical components from being oversaturated during cleaning.

Once the power is off and you are able to remove any large debris that is blocking the air condenser unit. This includes sweeping up any sticks, leaves or other debris that has accumulated on or around the unit. A shop vacuum that has a crevice tool is an excellent way to reach into the nooks, crannies and remove dust or dirt that has accumulated.

Next, it is time to clean the coils. Make sure you have the necessary tools on hand before you begin. These include a concentrate of the coil cleaner and a pump-up garden hose and a garden hose. Spray the coil cleaner in accordance with the directions on the product label and then rinse using the hose. It is essential 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 stones thrown by lawnmowers, and other objects can cause damage to the coil’s fins. If the fins are bent, a cost-effective tool known as a fin comb can straighten them for better air flow and also to aid in the operation of the coils more efficiently.

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

Clean the Ductwork

Your HVAC system works to bring outside air into your home, then cool it and then distribute it throughout the house. The air travels from the evaporator coil inside your condenser unit and then to your home’s vents and registers through a system of ducts. These ducts may become clogged with dust and other contaminants when they aren’t cleaned and sealed properly. This can block the air filters and reduces system efficiency and strains your AC unit.

In most cases, cleaning the ductwork is not an easy task that requires professional equipment and techniques. There are a few things you can do regularly to ensure that your ducts are clean and functioning properly. To prevent dust and allergens from accumulating in the ducts, change your filter regularly. This will also help to keep clogs from occurring, which could lead to a reduced system efficiency and a higher cost for energy.

Vacuuming the area around the vent openings is a different way to keep your ducts cleaner. Using the hose attachment on your vacuum cleaner can remove all cobwebs and crumbs that accumulate over time, and aid in improving airflow through the vent. It is also important to make sure your ducts are properly sealed and insulated to keep out moisture, which can lead to mold and other biological contaminants.

If ducts aren’t cleaned regularly, they can build up a myriad of contaminants like dust, pet dander, and pollen. These particles can cause respiratory and allergy conditions especially in the elderly and children. The moisture can cause mold to grow in the ductwork, which releases spores that are harmful to those suffering from respiratory ailments.

It is generally recommended that you get your ductwork cleaned every three to five years in order to eliminate these contaminates and ensure that your HVAC system functions effectively. However it is possible that if your ducts are sealed and you change your filters regularly it is possible that duct cleaning won’t be required at all. You can be certain by having your ducts examined. A contractor accredited by the EPA can use special testing methods in order to measure the amount particulates found in your ductwork. They will then suggest cleaning schedules that are suitable for your particular situation.

Check the Compressor

The compressor is an essential component of the system. It has to function properly to provide cool air to the ducts. If the compressor isn’t functioning properly, it can impact the efficiency of your business and lead to interruption to your equipment. Preventive maintenance can help identify minor issues earlier, avoiding unnecessary downtime. Regularly checking your unit can also help you save money by keeping your unit in good condition for as long as it is possible.

A common sign of a compressor issue is a reduction in cooling capacity, although it could be caused by a number of different factors. A compressor may be operating too hard due to poor airflow. This can cause wear on the bearings and diminish the life of the compressor. A clogged air filter is another frequent problem. Filters that are blocked can reduce airflow and cause the compressor to overheat. To prevent this, it is crucial to clean or change the filters on a regular basis, based on the manufacturer’s recommendation.

A clogged filter may also cause a sound of rattling in the compressor. This could be a sign that the bearings must be changed. Regularly replacing the belts and pulleys is an excellent idea. A worn-out belt or pulley can slip, causing the compressor to overheat, causing other issues. It’s also a good idea to drain your compressor on a regular basis. This will help remove moisture that can cause corrosion to the motor and other components. A professional service team will check for leaks in the pipes, and ensure an adequate seal around the compressor and pressure sensor.

A small puddle of water around the compressor could be a sign of a refrigerant leak. This is a serious problem and needs to be fixed immediately. If you suspect that there is a leak, switch off the compressor that is running and then contact a professional.

Check the Thermostat

It’s not a surprise that a technician will check the thermostat first when there is any issue. It’s also one of the most frequently neglected maintenance items, yet an appropriately maintained thermostat is vital to ensure your HVAC system’s optimal operation. Check your thermostat if notice incorrect temperature readings, unresponsive controls, or constant cycling.

Inaccurate Temperature Readings

Thermostat sensors can get dirty over time, which can cause the device to display incorrectly. You can avoid this issue by regularly checking the accuracy of your thermostat using a the use of a separate thermometer.

A defective sensor or a flawed calibration could cause your system to turn off and on in a continuous manner. This is known as short cycling. This could have a negative effect on your comfort as well as cause unnecessary wear and tears on the compressor. Fortunately the majority of these issues can be resolved with the simple act of replacing the thermostat’s batteries or resetting the breakers.

If your thermostat isn’t responding to your thermostat in any way it’s a good idea to check the breakers that regulate the thermostat as well as your HVAC equipment. If the breaker tripped it, you’ll need to reset it in order for your thermostat to reconnect with the system.

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

The simple maintenance of hvac systems on your commercial building is a great way to reduce the cost of energy, maintain comfort, and extend the longevity of your cooling and heating equipment. By identifying any issues with your thermostat, setting the breaker and replacing the batteries in the process, you’ll be able keep your building cool all year. Just remember that in case you experience any other issues or are unsure about the issue you should always consult an expert.
