The Importance of HVAC Maintenance
When it comes to your cooling and heating system, maintenance is essential to avoid costly repairs or premature replacement. The majority of HVAC companies offer a maintenance plan that charges a low monthly rate to have your system checked, fixed or cleaned as required.
It is also recommended to perform DIY maintenance throughout the year. Cleaning or replacing air filters, and keeping the area around outdoor units free of any debris will ensure the proper airflow.
Clean the Condenser
The coils in the condenser of your air conditioner are the mainstay of the cooling process. If they are dirty, you system will struggle to cool and may even fail. Cleaning them is an important part of HVAC maintenance. It is, fortunately, quite simple to do. This easy DIY task will eliminate the need for costly repairs, and save you money on your energy bills and prolong the longevity of your AC unit.
First and foremost, it is crucial to shut off the power supply to your unit. This can be done by shutting off the breaker in your electrical box or at the outdoor unit disconnect switch. This will safeguard your electrical components and motors from being over-saturated when cleaning.
When the power is turned off, you can begin to clean up any large debris that is blocking the air condenser unit. This includes taking away any sticks, leaves, or other debris that have built up on or around the unit. A shop vacuum equipped with crevice attachments is a great way to reach into the nooks and crannies and get rid of any dirt, dust or other debris that may have accumulated.
Next, it is time to clean the coils. Before you do this however, ensure you have some essential tools. These will include a concentrate of the coil cleaner, a pump-up garden sprayer and a garden hose. Spray the coil cleaner in accordance to the directions on the label, and then rinse with a water hose. It is important not to use excessive pressure when washing the coils because the fins may be bent.
You should inspect the coils for signs of damage following cleaning. Over time hail and stones thrown by lawnmowers, and other things can harm the coil fins. If the fins are bent, an affordable tool called a fin comb can straighten them for better air flow and help the coils function more effectively.
Once you have a good coil and fin setup, you can switch on your air conditioner. Make sure to check the thermostat after 24 hours to confirm that temperatures are within the normal range.
Cleaning the Ductwork
Your HVAC system works by bringing air in from outside, cooling it, and distributing it throughout your home. The air is transported from the evaporator of your condenser to your home’s registers and vents through a system of ducts. These ducts may become clogged with dust and other pollutants when they aren’t cleaned and sealed correctly. This clogs the air filters, which in turn reduces the efficiency of the system and puts strain on your AC unit.
Cleaning the ductwork can be a difficult task that requires expert equipment and techniques. There are a few things you can do to keep your ducts tidy and working well. To avoid dust and allergens from accumulating in the ducts, change your filter frequently. This will also help to stop clogging, which could cause a decrease in efficiency and higher energy bills.
Another way to help keep your ducts clean is to regularly cleaning the area around vent openings. Using the hose attachment on your vacuum cleaner can remove all dust and crumbs that build up over time, and help to improve air flow through the vent. It is also important to ensure that your ducts are tightly sealed and sealed with insulation to keep out moisture, which can cause mold and other biological contaminants.
If ducts are not cleaned regularly, they can collect a variety of pollutants such as dust, pet dander and pollen. These particles can cause a flare-up of respiratory and allergies, especially in children and the elderly. Moisture in ductwork can also result in the growth of mold, which releases spores in the air and can cause health issues for those who suffer from respiratory ailments.
It is generally recommended to get your ductwork cleaned every three to five years in order to eliminate these contaminants and ensure your HVAC system functions efficiently. If your ducts have been sealed well and you replace your filter on a regular basis It may not be necessary to clean them. The best way to determine the truth is to have your ducts tested. 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 recommend cleaning schedules that are appropriate for your situation.
Check the Compressor
The compressor is a critical component of the system. It has to function properly to provide cool air to the ducts. If the compressor isn’t operating as it should and isn’t functioning properly, it could impact your productivity and cause downtime for your equipment. Preventive maintenance can help spot minor issues early, preventing unnecessary downtime. These regular checks will also save you money by keeping your equipment in the best condition possible.
A loss of cooling capacity is a common indication of a problem with a compressor. This could be caused by several different factors. A compressor could be working too hard due to inadequate airflow. This can wear out the bearings and reduce the lifespan of the compressor. Another issue that is common is a blocked filter. If the filter has become clogged it can impede airflow to the compressor and cause overheating. To avoid this, it is essential to clean or change the filters regularly based on the recommendations of the manufacturer.
A blocked filter can cause a rattling sound in the compressor. This can indicate that the bearings are wearing out and must be replaced. Regularly replacing the belts and pulleys is recommended. A loose pulley or belt can slip and lead to overheating of the compressor and other issues. It is recommended to drain the compressor regularly. This will get rid of the moisture that could cause corrosion to the motor and other parts. A professional service team will also look for leaks in the hoses, and an adequate seal around the compressor and pressure sensor.
A pool of water in the vicinity of the compressor can be a sign of a refrigerant leak. This is a potentially dangerous problem that must be dealt with immediately. If you suspect that there is a leak, shut off the air compressor and contact an expert.
Check the Thermostat
It’s not a surprise that a technician will always examine the thermostat first if there’s an issue. It’s also among the most frequently neglected maintenance items, but an appropriately maintained thermostat is essential to ensure your HVAC system’s proper operation. Common signs that your thermostat is in need of a check-up include incorrect temperature readings, unresponsive controls, or continuous cycling.
Inaccurate Temperature Readings
Over time the sensors on your thermostat can become dirty. This can cause it to display incorrectly. Monitoring your thermostat’s accuracy regularly by using a separate thermometer can aid in avoiding these issues and save energy.
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 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 replacing the batteries in the thermostat or resetting the breaker.
If your system isn’t responding to your thermostat in any way it’s recommended to examine the breakers that control the thermostat as well as your HVAC equipment. If the breaker has been tripped, it will have to be reset in order for the thermostat to connect with the system.
Check your thermostat for indications of wear and tear. Examine for dust or dirt and make sure 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 possible.
The simple maintenance of hvac systems on your commercial property is an excellent method to cut energy costs, maintain comfort, and extend the longevity of your cooling and heating equipment. By identifying any issues with your thermostat, resetting the breaker, and replacing the batteries, you’ll be able to keep your building comfortable all year round. Be sure to call a professional in case you experience any other issues, or are unsure of what’s wrong with your system you should always consult a professional.
