The Importance of HVAC Maintenance
Maintenance is key when it is concerned with heating and cooling systems. It will help you avoid costly repairs or premature replacement. Most HVAC companies offer a maintenance plan that charges a low monthly rate to have the system checked, repaired or cleaned when necessary.
It is also recommended to perform DIY maintenance throughout the year. Cleaning or replacing air filters and keeping the area around the outdoor units free of any debris will ensure the proper airflow.
Clean the Condenser
The coils of the condenser of your air conditioner are the primary component of the cooling process. If they are dirty your system will struggle to cool properly and may even fail to function properly. Cleaning them is an important aspect of HVAC maintenance. It’s fairly easy to do. This easy DIY task can avoid the need for costly repairs, save you money on your energy bills and extend the longevity of your AC unit.
It is vital to cut off power from your unit before you disconnect it. This can be done by shutting off the breaker inside your electrical box or at the outdoor unit disconnect switch. This will prevent your motors and electrical components from being oversaturated during cleaning.
Once the power is off, you can begin taking down any large debris that could be hindering the condenser’s air. This includes taking away any leaves, sticks or other debris that have built up on or around the unit. A shop vacuum equipped with a crevice tool is an excellent way to reach into the nooks and crannies, and loosen dirt or dust that has been accumulating.
The coils need to be cleaned. Make sure you have a few essential tools available prior to beginning. This will include a concentrate of the coil cleaner, a pump-up garden sprayer and a garden hose. Spray the coil cleaner in accordance with the directions on the label of the product and then rinse using the hose. It is crucial not to apply too much pressure when washing the coils, as the fins can easily be bent.
After the coils have been cleaned, you should look them over for any signs of damage. Over time, hail and stones thrown by lawnmowers, and other items can damage the coil fins. If the fins are bent, a low-cost tool known as a fin-comb can straighten them to improve air flow and also to help the coils function more efficiently.
When the fins and coils are in good condition, you can go back to your home and turn on your air conditioner. Make sure to check the thermostat after 24 hours to make sure temperatures are within the normal range.
Cleaning the Ductwork
Your HVAC system is able to bring air from outside, cooling it, and distributing it throughout your home. Air is moved from the evaporator in your condenser unit to your home’s registers and vents through a system duct. If the ducts aren’t cleaned and sealed, they can become clogged with dust and other contaminants. This clogs the air filters and reduces the efficiency of your system and strains your AC unit.
In most cases, cleaning the ductwork is not an easy task that requires expert equipment and methods. There are some things you can do to keep your ducts tidy and working well. To avoid dust and allergens accumulating in the ducts, change your filter on a regular basis. This can also help stop the clogging that could cause a decrease in system efficiency and high 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, you can eliminate all the cobwebs and crumbs that accumulate over time, and aid in improving air flow through the vent. It is also essential to make sure your ducts are tightly sealed and insulated to keep out moisture, which can cause mold and other biological contaminants.
Ducts that aren’t cleaned on a regular basis are likely to be contaminated with a myriad of contaminants, such as dust, pet dander, and pollen. These particles can cause allergies and respiratory problems particularly in children and the elderly. In addition, moisture in ductwork may result in the growth of mold which releases spores in the air and poses health concerns for those who suffer from respiratory problems.
It is generally recommended that you have your ducts cleaned every three to five years to eliminate the toxins and ensure that your HVAC system functions 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 know the truth is to have your ducts examined. A contractor accredited by the EPA will use special testing methods in order to measure the amount particulates that are present in your ductwork. They can then recommend cleaning schedules that are suitable for your particular situation.
Check the Compressor
The compressor is a critical component of the system. It must be able to deliver cool air into 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 spot small issues early, preventing excessive downtime. Regularly checking your unit can also help you save money by keeping your unit in good working order for as long as it is possible.
A loss of cooling capacity is a common sign of a problem with a compressor. This could be caused by a variety of causes. One possibility is that the compressor may be overworking because of poor airflow. This can cause bearings to wear down and decrease the life of the compressor. A blocked air filter is another common issue. If the filter is blocked, it can reduce the airflow to the compressor, which can cause overheating. It is important to clean or change the filters in accordance with the manufacturer’s recommendations.
A blocked filter can cause a rattling sound in the compressor. This can indicate that the bearings are wearing out and must be replaced. It is also a good idea to replace belts and pulleys regularly. A pulley or belt that is loose can cause the compressor to overheat and cause other problems. It is also a good idea to drain your compressor frequently. This will get rid of the moisture that could cause corrosion to the motor and other components. A professional service team will examine for leaks in pipes, and ensure a tight seal on the compressor and pressure sensor.
A puddle of liquid close to the compressor could be a sign of an issue. This is a risky problem that must be dealt with immediately. If you suspect a leak, shut off the air compressor. Get a professional to assist you.
Check the Thermostat
It’s not a surprise that technicians will always check the thermostat first when there’s an issue. It’s also one of the most commonly overlooked maintenance items, yet a properly maintained thermostat is vital to ensure your HVAC system’s optimal operation. The most common signs that your thermostat is in need of periodic inspections include incorrect temperature readings, ineffective controls, or constant cycling.
Inaccurate Temperature Readings
Over time the sensors on your thermostat can become dirty. This can cause it to display in a wrong manner. Regularly checking your thermostat’s accuracy with a separate thermometer will assist you in avoiding these issues and conserve energy.
A malfunctioning sensor, or a faulty calibration can cause your system to turn off and on continuously. This is referred to as short cycling. This could have a negative effect on your comfort and result in excessive wear and tear on the compressor. Fortunately, these issues can often be corrected by simply replacing the batteries in your thermostat or resetting its breaker.
If your system isn’t responding to your thermostat in any way it’s recommended to examine the breakers that control the thermostat and your HVAC equipment. If the breaker has tripped, it’ll have to be reset to allow the thermostat to communicate with the system again.
Examine your thermostat for signs of wear and damage. Find evidence of dust or dirt, and make sure the thermostat isn’t exposed to sunlight. Examine the fan blades to find signs of rust and damage. These simple checks can help avoid expensive repairs in the future, and help ensure that your equipment is running as smoothly as possible.
The simple maintenance of hvac systems on your commercial property is an excellent way to cut down on the cost of energy, maintain comfort, and extend the lifespan of your heating and cooling equipment. You can ensure that your building stays comfortable throughout the year by identifying any issues with your thermostat, then resetting your breaker, and then replacing your batteries. Make sure to contact a professional if you are experiencing any other issues or are unsure of what’s wrong with your system.
