The Importance of HVAC Maintenance

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

It’s also recommended to do a few DIY maintenance tasks throughout the year. This includes cleaning or replacing air filters and keeping the space around outdoor units free of any debris to ensure the proper flow of air.

Clean the Condenser

The coils in your condenser for your air conditioner are the primary component of the cooling process. If they are dirty the system will struggle to cool properly and may even fail to function properly. Cleaning them is an important component of HVAC maintenance. It’s fairly easy to complete. This simple DIY task can avoid the need for expensive repairs, save you money on your energy bills and prolong the lifespan of your air conditioning unit.

It is crucial to disconnect power from your unit first. You can do this by turning off the breaker on your electrical box, or the outdoor unit disconnect switch. This will prevent your motors and other electrical components from being oversaturated when cleaning.

After the power has been turned off, you can begin clearing any large debris that could be blocking the condenser’s air. This includes sweeping away any sticks, leaves, or other debris that has built up on or around the unit. Utilizing a shop vacuum that has crevice attachments is a great way to get into the nooks and crannies and remove dust, dirt or other debris that has collected.

The next step is to clean the coils. Make sure you have some essential tools in your arsenal 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 instructions on the label of the product and then rinse it off using the hose. When washing the coils it is important not to apply too much force since the fins can be bent easily.

After the coils have been cleaned, examine them for indications of damage. Over time hail or stones thrown by lawnmowers, and other items can damage the coil fins. If the fins are bent, an affordable tool known as a fin-comb can straighten them to improve air flow and also to help the coils function more efficiently.

When you have a great coil and fin setup, you can start your air conditioner. After around 24 hours, you can examine the thermostat and make sure that the temperature is normal.

Clean the Ductwork

Your HVAC system is designed to bring outside air into your home, cool it and then distribute it throughout the house. Air is transported from the evaporator inside your condenser to your home’s registers and vents through a system ducts. The ducts could become blocked with dust and other contaminants when they aren’t maintained and sealed properly. This could block air filters, which decreases the effectiveness of your system as well as strains your AC unit.

Cleaning the ductwork can be a challenging task that requires specialized equipment and methods. There are a few actions you can take regularly to keep your ducts clean and in good working order. To avoid dust and allergens from accumulating in the ducts, it is recommended to change your filter regularly. This also helps to prevent the clogging that can cause a decrease in system efficiency and a high energy bill.

Vacuuming the area around the vent openings is a different method to keep your ducts in good shape. The hose attachment of your vacuum cleaner will get rid of all the cobwebs, crumbs and other messes that have accumulated over time. This will increase the flow of air through the vent. Also, make sure that your ducts are sealed well and are insulated to prevent moisture from 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 wide variety of contaminants, such as dust, pet dander and pollen. These particles can cause a flare-up of allergies and respiratory conditions particularly in children and the elderly. The moisture in ductwork can lead to the growth of mold which releases spores into air and poses health concerns for those with respiratory problems.

It’s generally recommended that you get your ductwork cleaned every three to five years to remove these contaminants and ensure your HVAC system is working efficiently. If your ducts have been well-sealed, and you replace your filter on a regular basis It may not be necessary to clean them. The best way to be able to tell the truth is to have your ducts examined. A licensed contractor can employ specific testing methods to determine the amount of particulates in your ductwork and can recommend appropriate cleaning schedules based on your particular situation.

Check the Compressor

The compressor is a critical element of the system. It should be able deliver cool air into the ducts. If the compressor isn’t working in the way it should, this can impact your productivity and cause delays for your equipment. Preventive maintenance can help spot minor issues earlier, avoiding excessive downtime. These regular checks will also save you money by making sure that your equipment as efficient as possible.

A decrease in cooling capacity is a common sign of a problem with the compressor. It could be caused by a variety of causes. One possibility is that a compressor may be working too hard due to poor airflow. This can cause the bearings to wear down and decrease the life of the compressor. Another common problem is a blocked filter. Filters that are blocked can restrict airflow and cause the compressor to overheat. It is crucial to change or clean the filters according to manufacturer’s recommendations.

A blocked filter may also cause rattling noises in the compressor. This could be a sign that the bearings require to be replaced. It is recommended to replace belts and pulleys on a regular basis. A worn belt or pulley could cause slipping and result in overheating of the compressor and other issues. It is also a good idea to drain the compressor on a regular basis. This will eliminate moisture that can cause corrosion to the motor and other parts. A professional service team will also look for air leaks in the hoses and a tight seal between the compressor and pressure switch.

A puddle of liquid close to the compressor could be an indication of an issue. This could be a dangerous problem that should be addressed immediately. If you suspect that there is a leak, shut off the air compressor. Consult a professional.

Check the Thermostat

It’s not surprising that a technician will check the thermostat first when there is a problem. It’s also among the most commonly overlooked maintenance items, but an appropriately maintained thermostat is crucial for ensuring your HVAC system’s operation. Check your thermostat if you find inaccurate temperature readings, ineffective controls, or constant cycling.

Inaccurate Temperature Readings

Thermostat sensors can get dirty over time, which could cause the thermostat to display inaccurately. You can avoid these problems by ensuring the accuracy of your thermostat with a separate thermometer.

A malfunctioning sensor, or a wrong calibration, could cause your system to cycle on and off continuously. This is referred to as short cycling. This can have a negative impact on your comfort and cause excessive wear and tear on the compressor. The problem can be fixed by simply 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 both the thermostat as well as your HVAC equipment. If the breaker has tripped then you’ll have to reset it to allow your thermostat to communicate again with the system.

It’s also important to check your thermostat for any signs of wear or damage. Examine for dust or dirt and make sure that the thermostat is not too much exposed to sunlight. Check the fan blades for evidence of damage or rust. These simple checks can prevent costly repairs in the future, and ensure that your equipment runs as smoothly as it possibly can.

Performing basic hvac maintenance on your commercial property is a great way to reduce energy consumption, ensure comfort and extend the lifespan of your cooling and heating equipment. By identifying problems with your thermostat, setting the breaker, and replacing the batteries and fuses, you’ll be able keep your building comfortable 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.
