The Importance of HVAC Maintenance
Maintenance is key when it is concerned with HVAC and cooling systems. It will help you avoid costly repairs or premature replacement. Most HVAC companies offer a maintenance plan that charges an affordable monthly fee to get the system checked out, fixed or cleaned as needed.
It’s also a good idea to perform some of the DIY maintenance tasks throughout the year. These include cleaning or replacing air filters, and keeping the area around outdoor units free of debris to promote the proper airflow.
Clean the Condenser
The coils in your air conditioner condenser are at the heart the cooling process. If they are dirty the system will be unable to cool properly and could even fail. Cleaning them is a crucial part of HVAC maintenance. It is, fortunately, relatively simple to complete. This easy DIY task can avoid the need for costly repairs, save you money on your energy bills and extend the lifespan of your air conditioning unit.
It is vital to cut off power from your unit first. This can be done by shutting off the breaker inside your electrical box or at the outdoor unit disconnect switch. This will prevent your electrical components and motors from being oversaturated during cleaning.
After the power has been turned off, you can start clearing any large debris that may be hindering the condenser’s air. This includes sweeping off any sticks, leaves or other debris that have built up on or around the unit. Utilizing a shop vacuum that has crevice attachments is a great way to get into the crevices and nooks and remove any dirt, dust or other debris that may have accumulated.
The next step is to clean the coils. Be sure to have the necessary tools available before you start. Included in this are coil cleaning concentrates and a pump-up garden sprayer and a garden hose. Spray the coil cleaner according to the directions on the label, then rinse it off with a hose. It is essential not to apply excessive pressure when washing the coils as the fins can easily be bent.
It is recommended to inspect the coils for signs of damage following cleaning. Over time, hail and rocks thrown from lawnmowers or other items could 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 assist in ensuring that the coils operate more efficiently.
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 turn on your air conditioning. After approximately 24 hours, you should check the thermostat and make sure that the temperature is normal.
Cleaning the Ductwork
Your HVAC system is able to bring outside air into your home, cool it and then distribute it throughout the home. Air is transported from the evaporator in the condenser to your home’s registers and vents via the system duct. These ducts may become clogged with dust and other pollutants when they aren’t cleaned and sealed properly. This can clog the air filters which can reduce the efficiency of your system and can strain your AC unit.
In most cases, cleaning the ductwork isn’t an easy task and requires the help of professional equipment and methods. However, there are a few actions you can take on a regular basis to make sure your ducts are in good condition and function properly. First, make sure you change your filter regularly to prevent dust and allergens out of building up in the ducts. This will also help to keep the clogs from occurring which can lead to reduced system efficiency and a high energy bill.
Cleaning the area around the vent openings is a different way to keep your ducts cleaner. Utilizing the hose attachment of 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’s also important to make sure your ducts are sealed and insulated to keep out moisture which can lead to mold and other biological contaminants.
If ducts aren’t cleaned regularly, they can accumulate a variety of contaminants such as dust, pet dander and pollen. These particles can trigger respiratory issues and allergies particularly for older people and children. Moisture can cause mold to grow in the ductwork, releasing the spores that can be harmful to people suffering from respiratory issues.
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 are sealed properly, and you regularly change your filter it might not be necessary to clean them. You can be certain by having your ducts checked. A certified contractor can employ special testing methods to measure the amount of dust particles in your ductwork and will suggest appropriate cleaning schedules that are based on the specific circumstances.
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 it could affect your productivity and result in the equipment to shut down. Fortunately, preventive maintenance is able to aid in identifying minor issues early and help avoid prolonged downtime. These regular checks will also save you money by keeping your equipment as efficient as possible.
A typical sign of a compressor problem is a reduction in cooling capacity, however it could be caused by various factors. A compressor may be working too hard due insufficient airflow. This can cause the bearings to wear out and reduce the lifespan of the compressor. A blocked air filter is a different problem. Filters that are clogged can hinder airflow and cause the compressor to overheat. It is essential to clean or replace the filters according to manufacturer’s instructions.
Additionally, a blocked filter may also cause a rattling sound 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 on a regular basis. A loose belt or pulley can cause the compressor to overheat and create other problems. It’s also a good idea to drain your compressor on a regular basis. This will remove the accumulated moisture that could cause corrosion to the motor and other components. A professional service team can examine for air leaks within the hoses and an adequate seal between the compressor and the pressure switch.
A puddle of liquid in the vicinity of the compressor could be a sign of leak. This could be a dangerous problem that should be addressed immediately. If you suspect there is a leak, switch off the compressor that is running and then contact a professional.
Check the Thermostat
It’s not too surprising that a technician will look at the thermostat first when there is a problem. A properly maintained thermostat is crucial to the proper operation of your HVAC system. It’s one of the most frequently neglected maintenance items. Examine your thermostat if you notice incorrect temperature readings, ineffective controls or constant cycling.
Inaccurate Temperature Readings
Over time, the sensors on your thermostat may get dirty. This could cause it to display incorrectly. You can avoid this issue by regularly checking 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 known as short cycling. This can have a negative impact on your comfort and cause unnecessary wear and tears on the compressor. The problem can be fixed by simply replacing the batteries in the thermostat or resetting the breaker.
If your thermostat isn’t responding to your thermostat at all it’s an excellent idea to look at the breakers that control the thermostat as well as your HVAC equipment. If the breaker tripped it, you’ll need to reset it to allow your thermostat to communicate again with the system.
It is also essential to examine your thermostat for any signs of wear or damage. Look for evidence of dust or dirt, and make sure the thermostat isn’t exposed to sunlight. Finally, the fan blades need to be examined for signs of rust or damage. These simple checks will help prevent expensive repairs in the future, and ensure your equipment is operating as efficiently as possible.
The simple maintenance of hvac systems on your commercial property is an excellent way to cut down on energy consumption, ensure comfort and extend the lifespan of your heating and cooling equipment. It is possible to keep your building at all times comfortable by identifying problems with your thermostat, setting your breaker and replacing your batteries. Just remember that should you encounter any other issues, or aren’t sure what’s wrong with your system you should always consult an expert.
