The Importance of HVAC Maintenance

Maintenance is key when it comes to HVAC and cooling systems. It will allow you to avoid costly repairs or premature replacement. The majority of HVAC companies offer a service plan where you pay an annual fee to have your system checked and cleaned or repaired when required.

You should also carry out some DIY maintenance throughout the year. This includes cleaning or replacing air filters and keeping the areas around outdoor units clear of debris to promote the proper airflow.

Clean the Condenser

The coils inside your air conditioner’s condenser are the heart of the cooling process. If they are dirty your system will be unable to cool properly and could even fail. This is why cleaning them is a crucial aspect of HVAC maintenance. It is relatively easy to complete. This simple DIY task will save you money, prevent expensive repairs and extend the life of your air conditioner.

It is the first step. It is essential to cut off the power to your unit. This can be accomplished by turning off the breaker in the electrical box, or by turning off the outdoor unit disconnect switch. This will prevent your motors and other electrical components from becoming oversaturated when cleaning.

After the power has been shut off and you are able to clean up any large debris that is obstructing the air condenser unit. This includes cleaning up any sticks, leaves or other debris that have built up on or around the unit. A shop vacuum equipped with a crevice tool is a great way to reach into the nooks and crannies, and loosen dirt or dust that has accumulated.

The coils require to be cleaned. Before you begin, though, make sure that you have on-hand some essential tools. This will include a concentrate for coil cleaning, a pump-up garden sprayer and a garden hose. Spray the coil cleaner in accordance with the directions on the product label and then rinse using the hose. When washing the coils, it is essential not to use excessive force since the fins can bend easily.

After the coils have been cleaned, you should inspect them for any signs of damage. Over time, hail, rocks 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 to help the coils function more efficiently.

Once you have a good coil and fin set up and you are ready to start your air conditioner. Check the thermostat after about 24 hours to make sure temperatures are normal.

Cleaning 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. If these ducts aren’t cleaned and sealed, they could become loaded with dirt and other contaminates. This can clog the air filters, which decreases the effectiveness of your system and burdens your AC unit.

Cleaning ductwork can be a challenging task that requires professional equipment and methods. There are some things you can do to keep your ducts tidy and in good working order. To avoid dust and allergens from accumulating in the ducts, change your filter on a regular basis. This also helps to keep the clogs from occurring which can cause a decrease in system efficiency and high energy bills.

Another method to keep your ducts tidy is to regularly cleaning the area around vent openings. The hose attachment of your vacuum cleaner will remove all the crumbs, cobwebs and other debris that has built up over time. This will improve airflow through the vent. It is also important to ensure that your ducts are sealed tight and lined to stop moisture from getting in, which could lead to mold and other biological contaminants.

If ducts are not regularly cleaned, they may collect a variety of pollutants like dust, pet dander, and pollen. These particles can trigger respiratory and allergies, especially in children and the elderly. In addition, moisture in ductwork may result in the growth of mold which releases spores in the air and can cause health issues for those suffering from respiratory issues.

It is recommended to clean your ductwork every three to five years to get rid of these toxins and ensure that your HVAC system is functioning efficiently. If your ducts are sealed well and you regularly change your filter, it may not be necessary to clean them. You can only be sure that your ducts are in good condition by having them checked. A certified contractor can employ special testing methods to measure the amount of particulates in your ductwork, and can recommend appropriate cleaning schedules based on your specific situation.

Check the Compressor

The compressor is an essential element of the system. It needs to operate properly to deliver cool air to the ducts. If the compressor isn’t operating as it should, this can impact the efficiency of your business and lead to downtime for equipment. Regular maintenance can help you identify minor issues earlier, avoiding unnecessary downtime. Regular checks can also save you money by making sure that your unit as good as possible.

A reduction in cooling capacity is a typical indication of a problem with the compressor. This could be caused by a variety of factors. One possibility is that the compressor may be overworking because of 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. If the filter is clogged, it can reduce the airflow to the compressor and cause overheating. To avoid this, it is crucial to clean or change the filters on a regular basis, based on the manufacturer’s recommendation.

Additionally, a blocked filter could create a rattling sound inside the compressor. This could mean that the bearings are wearing out and must be replaced. It is also a good idea to replace pulleys and belts on a regular basis. A pulley or belt that is loose could cause the compressor to overheat and create other problems. It is recommended to drain the compressor on a regular basis. This will eliminate moisture that can cause corrosion to the motor and other components. A professional service team will check for leaks in the hoses, as well as a tight seal on the compressor and pressure sensor.

A puddle of water near the compressor could be a sign of a refrigerant leak. This can be a dangerous issue that needs to be addressed immediately. If you suspect that there is a leak, shut off the air compressor. Get a professional to assist you.

Check the Thermostat

The thermostat acts like the head of your HVAC system, and it’s not surprising that it’s the first thing that a technician will check when trouble arises. A properly maintained thermostat is essential for the efficient operation of your HVAC system. It’s one of the most frequently neglected maintenance items. Common indicators that your thermostat requires periodic inspections include incorrect temperature readings, unresponsive controls, or continuous cycling.

Inaccurate Temperature Readings

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

A faulty sensor or calibration can also result in your system constantly switching off and on that is known as short cycling. This can affect your comfort and result in unnecessary wear and tear on the compressor. Fortunately the majority of these issues can be fixed with simply replacing the thermostat’s batteries or resetting its breaker.

Make sure you check the breakers on both your thermostat and HVAC equipment if your system doesn’t respond to your thermostat. If the breaker has tripped then you’ll have to reset it in order for your thermostat to reconnect with the system.

Check your thermostat for indications of wear and damage. Check for indications of dust or dirt and ensure that the thermostat isn’t overly exposed to sunlight. Examine the fan blades to find signs of rust and damage. These simple checks can prevent expensive repairs in the future, and will ensure that your equipment is operating as efficiently as it can.

Conducting basic HVAC maintenance on your commercial building is an excellent way to cut down on energy costs, maintain comfort, and extend the lifespan of your heating and cooling equipment. By identifying any issues with your thermostat, resetting the breaker, and then replacing the batteries, you’ll be able to keep your building cool all year round. Just remember that if you have any other issues, or are unsure about what’s wrong with your system make sure to contact a professional.
