The Importance of HVAC Maintenance
Maintenance is key when it comes to heating and cooling systems. It can help you avoid costly repairs or premature replacement. Most HVAC companies offer a maintenance plan that charges the monthly cost to get the system checked, fixed or cleaned when required.
It’s also a good idea to perform a few DIY maintenance tasks throughout the year. These include cleaning or replacing air filters and keeping the space around outdoor units free of debris to promote the proper airflow.
Clean the Condenser
The coils of your air conditioner condenser are the core of the cooling process. If they’re dirty the system will be unable to cool properly and may even break down. This is why cleaning them is a vital aspect of HVAC maintenance. It is relatively easy to complete. This simple DIY task can prevent the need for expensive repairs, and save you money on your energy bills and extend the lifespan of your air conditioning unit.
It is essential to disconnect power from your unit before you disconnect it. This can be accomplished by shutting off the breaker in your electrical box or by turning off the outdoor unit disconnect switch. This will keep your motors and other electrical components from becoming oversaturated while cleaning.
Once the power is off it is now time to clean up any large debris obstructing the air condenser unit. This means taking away any sticks, leaves, or other debris that have accumulated on or around the unit. A shop vacuum with crevice tools is a great way to get into the nooks and crannies and remove dust or dirt that has built up.
Next, it is time to clean the coils. Before doing this, though, make sure that you have in your possession some essential tools. These will include a coil cleaner concentrate and a pump-up garden sprayer and a garden hose. Spray the coil cleaner in accordance to the directions on the label, and then rinse it off using the water hose. It is essential not to apply excessive pressure when washing the coils as the fins can easily be bent.
After the coils have been cleaned, you should examine them for signs of damage. Over time hail or rocks thrown by lawnmowers and other things can harm the coil fins. If the fins are bent, a low-cost tool called a fin comb can straighten them to improve air flow and to assist in ensuring that the coils operate more effectively.
Once the coils and fins are in good condition Once you’re satisfied with the condition of the fins and coils, you can go back to your home and start your air conditioner. After about 24 hours, you can check the thermostat to ensure that the temperature is normal.
Cleaning the Ductwork
Your HVAC system works to bring air from outside into your home, cool it, and then distribute it throughout your home. The air moves from the evaporator coil of your condenser unit and then to your home’s vents and registers through a system of ducts. If these ducts aren’t properly cleaned and sealed, they could become loaded with dust and other contaminants. This could block air filters which reduces the effectiveness of your system as well as can strain your AC unit.
In the majority of cases, cleaning the ductwork isn’t an easy task and requires the help of professional equipment and techniques. There are a few things you can do regularly to keep your ducts clean and functioning properly. First, change your filter regularly to keep dust and allergens from building in the ducts. This will also help to prevent the clogging that can cause a decrease in system efficiency and a high energy bill.
Cleaning the area around the vent openings is a different method to keep your ducts cleaner. By using the hose attachment on your vacuum cleaner can remove all cobwebs and crumbs that accumulate over time and help to improve air flow through the vent. Also, make sure that your ducts have been sealed well and are lined to stop moisture from getting in, which could result in mold and other biological contaminants.
If ducts are not cleaned regularly, they could build up a myriad of contaminants such as dust, pet dander and pollen. These particles can exacerbate respiratory issues and allergies, especially in children and the elderly. Moisture can cause mold to grow in the ductwork, which releases the spores that can be harmful to those suffering from respiratory ailments.
It is recommended to clean your ducts once every three to five years to get rid of these toxins and ensure that your HVAC system is functioning 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. You can only be sure by having your ducts checked. A contractor accredited by the EPA will use special testing techniques to determine the amount of particles present in your ductwork. They will then recommend cleaning schedules that are suitable for your particular situation.
Check the Compressor
The compressor is an essential element of the system. It needs to operate properly to provide cool air to the ducts. If the compressor isn’t working properly, it could affect your productivity and cause downtime for equipment. Regular maintenance can help you identify minor issues early, preventing unnecessary downtime. Regularly checking your unit can also save you money by keeping your unit in good condition for as long as it is possible.
A loss of cooling capacity is a typical sign of a problem with a compressor. This could be caused by a variety of causes. A compressor could be working too hard due to inadequate airflow. This can cause the bearings to wear down and reduce the lifespan of the compressor. Another common problem is a clogged filter. Filters that are clogged can hinder airflow and cause the compressor to overheat. To prevent this, it is essential to clean or change the filters regularly based on the recommendations of the manufacturer.
Additionally, a blocked filter may also cause rattling noises in the compressor. This could indicate that the bearings are wearing out and need to be replaced. It is recommended to replace belts and pulleys regularly. A worn belt or pulley can cause slippage and cause compressor overheating and other issues. It is recommended to drain the compressor regularly. This will remove the moisture that could cause corrosion to the motor and other components. A professional service team can also examine for air leaks within the hoses, and ensure a tight seal between the compressor and the pressure switch.
A puddle of liquid near the compressor could be an indication of an issue. This could be a dangerous issue that needs to be addressed immediately. If you suspect that there is a leak, shut off the air compressor. Contact a professional.
Check the Thermostat
It’s not surprising that a technician will always check the thermostat first when there is any issue. It’s also one of the most often neglected maintenance items, yet maintaining your thermostat properly is essential to ensure your HVAC system’s optimal operation. The most common signs that your thermostat is in need of a check-up include incorrect temperature readings, unresponsive controls, or continuous cycling.
Inaccurate Temperature Readings
Thermostat sensors may become dirty over time, which may cause the device to display inaccurately. You can avoid this issue by regularly checking the accuracy of your thermostat using a an additional thermometer.
A defective sensor or a faulty calibration can cause your system to turn off and on constantly. This is referred to as short cycling. This can have a negative impact on your comfort as well as cause excessive wear and tear on the compressor. This issue can be solved by simply replacing the thermostat’s batteries or resetting the breaker.
If your thermostat isn’t responding to your thermostat in any way it’s recommended to examine the breakers that regulate the thermostat and your HVAC equipment. If the breaker has tripped, you will need to reset it in order for your thermostat to communicate again with the system.
Examine your thermostat for signs of wear and tear. Look for dust or dirt and ensure that the thermostat is not too much exposed to sunlight. Examine the fan blades for signs of rust and damage. These simple checks will help prevent expensive repairs in the future, and will ensure that your equipment is operating as smoothly as it is possible.
Performing basic hvac maintenance on your commercial property is an excellent way to cut down on the cost of energy, maintain comfort and extend the longevity of your cooling and heating equipment. By identifying issues with your thermostat, setting the breaker and replacing the batteries and fuses, you’ll be able keep your building cool all year. Make sure that in case you experience any other issues or are unsure about what’s wrong with your system make sure to contact an expert.
