The Importance of HVAC Maintenance

Maintenance is key when it comes to heating and cooling systems. It will help you avoid costly repairs or premature replacement. The majority of HVAC companies offer a maintenance plan that charges a low monthly rate to have the system checked, fixed or cleaned as needed.

It’s also an excellent idea to carry out some of the DIY maintenance tasks throughout the year. This includes 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 of your air conditioner are the primary component of the cooling process. If they are dirty, you system will struggle to cool and could even fail. Cleaning them is an essential component of HVAC maintenance. It is relatively easy to do. This easy DIY task will save you money, avoid costly repairs, and increase the life span of your air conditioner.

It is crucial to disconnect power from your unit before you disconnect it. This can be done by turning off the breaker in the electrical box, or the outdoor unit disconnect switch. This will stop your motors and other electrical components from becoming oversaturated during cleaning.

After the power has been shut off, you can begin clearing any large debris that may be blocking the condenser air. This means sweeping away any sticks, leaves or other debris that has accumulated on or around the unit. A shop vacuum that has a crevice tool is an excellent way to get into the nooks, crannies and remove dust or dirt that has built up.

The coils must be cleaned. Make sure you have a few essential tools on hand before you start. Included in this are coil cleaning concentrates, a pump up garden sprayer, and a garden hose. Spray the coil cleaner according to the directions on the product label and then rinse it off using the hose. It is important not to use too much pressure when washing the coils as the fins can easily be bent.

You should examine the coils for signs of damage after cleaning. Over time hail, rocks thrown by lawnmowers and other objects can cause damage to the coil’s fins. Fin combs are a great way to straighten bent fins to ensure improved airflow and coil performance.

When you have a great coil and fin set up and you are ready to turn on your air conditioner. After about 24 hours, you should check the thermostat to ensure that the temperature is normal.

Cleaning the Ductwork

Your HVAC system works by bringing air from outside, cooling it and distributing it throughout your home. Air is moved from the evaporator of your condenser to your home’s registers and vents via the system duct. These ducts can become clogged with dust and other contaminants when they aren’t maintained and sealed properly. This clogs the air filters and reduces system efficiency and puts strain on your AC unit.

In most instances, cleaning ductwork isn’t an easy task that requires professional equipment and techniques. However, there are a few actions you can take regularly to ensure that your ducts stay clean and well-functioning. To avoid dust and allergens from accumulating in the ducts, it is recommended to change your filter regularly. This can also help stop clogging, which could result in a decrease in system efficiency and a higher cost for energy.

Vacuuming the area around the vent openings is another way to keep your ducts clean. By using the hose attachment on your vacuum cleaner, you can eliminate all of the dust and crumbs that build up over time and help to improve air flow through the vent. You should also make sure that your ducts are sealed tight and insulated to prevent moisture from entering, which can result in mold and other biological contaminants.

If ducts aren’t regularly cleaned, they may accumulate a variety of contaminants like dust, pet dander, and pollen. These particles can exacerbate allergies and respiratory problems particularly for children and the elderly. The moisture can cause mold to grow in the ductwork, which releases spores that are harmful to people suffering from respiratory issues.

It is generally recommended to get your ductwork cleaned every three to five years to remove these contaminants and ensure your HVAC system is working efficiently. However it is possible that if your ducts are sealed properly and you change your filters regularly, duct cleaning may not be required at all. The best way to know for sure is by having your ducts examined. A contractor accredited by the EPA can employ specific testing methods to determine the amount of particulates that are present in your ductwork. They will then suggest cleaning schedules that are suitable for your specific situation.

Check the Compressor

The compressor is an essential element of the system. It must function properly to provide cool air to the ducts. If the compressor isn’t operating as it should, this can impact the efficiency of your business and lead to delays for your equipment. Preventive maintenance can help identify minor issues early, preventing unnecessary downtime. Regularly checking your unit can also save you money by keeping your unit in good working order for as long as possible.

A reduction in cooling capacity is a typical sign of a problem in the compressor. This can be caused by a variety of factors. One possibility is that the compressor may be overworking because of poor airflow. This can cause wear on the bearings and reduce the lifespan of the compressor. Another issue that is common is a clogged filter. If the filter has become clogged it can impede airflow to the compressor, which can cause overheating. To avoid this, it is crucial to clean or change the filters regularly based on the recommendations of the manufacturer.

In addition, a clogged filter may also cause rattling noises in the compressor. This could indicate that the bearings require to be replaced. It is recommended to replace pulleys and belts on a regular basis. A loose belt or pulley could cause the compressor to overheat, causing other problems. It is also a good idea to drain the compressor on a regular basis. This will help remove moisture that can corrode the motor and other components. A professional service team can also check for air leaks in the hoses, and ensure a tight seal between the compressor and pressure switch.

A puddle of water near the compressor could be an indication of a refrigerant leak. This could be a dangerous problem that should be addressed immediately. If you suspect a leak, shut off the air compressor. Consult a professional.

Check the Thermostat

The thermostat is like the head of your HVAC system, so it’s not surprising that it’s the first thing a technician will look at when trouble occurs. A properly maintained thermostat is essential for the smooth operation of your HVAC system. It’s among the most neglected maintenance items. Examine your thermostat if you find inaccurate temperature readings, unresponsive controls, or constant cycling.

Inaccurate Temperature Readings

Thermostat sensors can become dirty over time, which could cause the device to display incorrectly. You can avoid this issue by regularly checking the accuracy of your thermostat using a a separate thermometer.

A defective sensor or a wrong calibration, could cause your system to turn off and on in a continuous manner. This is known as short cycling. This could have a negative effect on your comfort as well as cause excessive wear and tear on the compressor. Fortunately the majority of these issues can be corrected by the simple act of replacing the thermostat’s batteries or resetting its breaker.

If your thermostat isn’t responding to your thermostat at all it’s an excellent idea to look at the breakers that regulate the thermostat as well as your HVAC equipment. If the breaker has tripped, you will need to reset it to allow your thermostat to be able to communicate with the system.

Check your thermostat for indications of wear and tear. Look for evidence of dust or dirt, and make sure the thermostat isn’t too exposed to sunlight. Examine the fan blades to find signs of damage and rust. These simple checks will help prevent costly repairs in the near future, and help ensure that your equipment is operating as efficiently as it is possible.

Basic hvac maintenance is a great method to save energy and keep your comfort in a commercial space. It will also extend the lifespan of heating and cooling equipment. By identifying issues with your thermostat, setting the breaker, and replacing the batteries in the process, you’ll be able keep your building comfortable all year round. Be sure to call an expert if you’re experiencing any other issues or unsure of what is going on with your system.
