The Importance of HVAC Maintenance
Maintenance is key when it is concerned with HVAC and cooling systems. It can help you avoid costly repairs or premature replacement. Most HVAC companies offer a service plan that charges the monthly cost to get the system checked, fixed or cleaned when required.
It’s also recommended to do some of the DIY maintenance tasks throughout the year. These include cleaning or replacing air filters and keeping the areas around outdoor units clear of any debris to ensure the proper airflow.
Clean the Condenser
The coils in the condenser in your air conditioner are the mainstay of the cooling process. If they’re dirty, you system will struggle to cool, and it could even breakdown. This is why cleaning them is a vital aspect of HVAC maintenance. It’s fairly easy to do. This simple DIY task will eliminate the need for expensive repairs, and save you money on your energy bills and prolong the lifespan of your air conditioning unit.
First and foremost, it is crucial to shut off the power source 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 safeguard your electrical components and motors from being over-saturated when cleaning.
When the power is turned off it is now time to clean up any large debris blocking the air condenser unit. This means sweeping up any sticks, leaves, or other debris that have accumulated around or on the unit. A shop vacuum that has a crevice tool is an excellent way to reach into the nooks, crannies, and loosen dirt or dust that has built up.
The coils must be cleaned. Be sure to have some essential tools available before you start. These include a concentrate for coil cleaning and a pump-up garden hose and a garden hose. Spray the coil cleaner in accordance to the directions on the label, and then rinse it off with a garden hose. When washing the coils, it is important not to apply too much force as the fins are easily bent.
You should examine the coils for signs of damage after cleaning. Over time, hail and rocks dropped by lawnmowers or other items could damage the coil fins. If the fins are bent, a cost-effective tool called a fin comb can straighten them for better air flow and to help the coils function more efficiently.
When the fins and coils are in good shape If you are satisfied with the condition of your fins and coils, return to your house and start your air conditioning. Make sure to check the thermostat after 24 hours to confirm that temperatures are normal.
Clean the Ductwork
Your HVAC system is able to bring air from outside, cooling it and distributing it throughout the home. The air travels from the evaporator coil in your condenser unit to your home’s vents and registers through a duct system. These ducts can become clogged with dust and other pollutants if they are not cleaned and sealed properly. This can block the air filters which can reduce the effectiveness of your system and can strain your AC unit.
In most instances, cleaning ductwork isn’t an easy job and requires the help of professional equipment and methods. There are some things you can do regularly to keep your ducts tidy and functioning properly. To stop dust and allergens accumulating in the ducts, it is recommended to change your filter on a regular basis. This will also help keep clogs from occurring, which could result in a decrease in system efficiency and higher energy costs.
Cleaning the area around the vent openings is another method to keep your ducts clean. The hose attachment on your vacuum cleaner will take away all the cobwebs, crumbs and other debris that have been accumulating over time. This will increase airflow through the vent. Also, make sure that your ducts are sealed tight and lined to stop moisture from entering, which can result in mold and other biological contaminants.
If ducts aren’t cleaned regularly, they can collect a variety of pollutants like dust, pet dander, and pollen. These particles can exacerbate respiratory and allergies particularly in children and the elderly. Moisture can also cause mold to grow in the ductwork, which releases the spores that can be harmful to those suffering from respiratory ailments.
It’s generally recommended that you get your ductwork cleaned every three to five years to eliminate the toxins and ensure that your HVAC system is operating efficiently. However If your ducts are sealed properly and you change your filters regularly, duct cleaning may not be necessary at all. The best way to determine for sure is by having your ducts tested. A contractor that is certified by the EPA will use special testing methods in order to determine the amount of particles found in your ductwork. They can then recommend cleaning schedules that are suitable for your particular situation.
Check the Compressor
The compressor is an essential element of the system. It has to function correctly to supply cool air to the ducts. If the compressor isn’t functioning as it should, this could affect the efficiency of your business and lead to delays for your equipment. Fortunately, preventive maintenance can assist in identifying issues that are minor and prevent unnecessary downtime. Conducting these regular checks can also save you money by keeping your unit in good condition for as long as it is possible.
The most common sign of a compressor problem is a reduction in cooling capacity, although this could be caused by various factors. A compressor may be working too hard due to inadequate airflow. This can cause the bearings to wear out and decrease the life of the compressor. Another issue that is common is a clogged filter. If the filter has become clogged, it can reduce the airflow to the compressor, which can cause overheating. It is essential to clean or replace the filters in accordance with the manufacturer’s guidelines.
In addition, a clogged filter may also cause rattling noises in the compressor. This could indicate that the bearings are wearing out and must be replaced. It is also a good idea to replace pulleys and belts regularly. A loose pulley or belt could cause slipping and result in overheating of the compressor and other issues. It is recommended to drain the compressor on a regular basis. 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 as well as a tight seal between the compressor and pressure switch.
Lastly, a small puddle of water around the compressor can be a sign of a refrigerant leak. This could be a risky issue and should be repaired immediately. If you suspect there is a leak, switch off the air compressor and contact a professional.
Check the Thermostat
It’s not a surprise that a technician will look at the thermostat first when there’s an issue. It’s also one of the most frequently neglected maintenance items, yet an appropriately maintained thermostat is crucial for ensuring your HVAC system’s proper operation. Common indicators that your thermostat is in need of periodic inspections include incorrect temperature readings, unresponsive controls, or constant cycling.
Inaccurate Temperature Readings
Thermostat sensors can become dirty over time, which could cause the thermostat to display inaccurately. You can prevent these issues by checking the accuracy of your thermostat by using a an additional thermometer.
A malfunctioning sensor or calibration can also result in your system constantly switching on and off that is known as short cycling. This can have a negative impact on your comfort and result in unnecessary wear and tears on the compressor. Fortunately, these issues can often be fixed with simply replacing the thermostat’s batteries or resetting its breaker.
If your thermostat isn’t responding to your thermostat at all it’s a good idea to check the breakers that regulate the thermostat as well as your HVAC equipment. If the breaker tripped it, you’ll need to reset it to allow your thermostat to be able to communicate with the system.
Check your thermostat for signs of wear and damage. Find signs of dirt or dust and ensure that the thermostat isn’t too exposed to sunlight. The fan blades should be checked for signs of rust or damage. These simple checks can help avoid costly repairs in the future, and ensure your equipment is operating as efficiently as it is possible.
Basic maintenance of hvac is a great strategy to cut down on energy costs and maintain comfort in your commercial property. It also increases the lifespan of heating and cooling equipment. You can ensure that your building stays cool throughout the year by identifying problems with your thermostat, resetting your breaker, and then replacing your batteries. Make sure to contact a professional if you are having any other problems or unsure of what is the issue with your system.
