The Importance of HVAC Maintenance

When it concerns your heating and cooling system, regular maintenance is the key to avoiding costly repairs or replacements that are not needed as soon as they should be. The majority of HVAC companies have a maintenance plan that charges a monthly fee to have the system checked, repaired or cleaned as needed.

It’s also recommended to do a few 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 inside your air conditioner’s condenser are the core 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 a crucial aspect of HVAC maintenance. It’s relatively simple to complete. This easy DIY task will save you money, avoid expensive repairs and extend the lifespan of your air cooling.

It is essential to disconnect power from your unit first. You can do this by shutting off the breaker on your electrical box, or the outdoor unit disconnect switch. This will safeguard your motors and electrical components from being flooded when cleaning.

After the power has been turned off, you can start removing any large debris that could be blocking the condenser air. This means sweeping up any sticks, leaves or other debris that has been accumulating around or on the unit. Using a shop vacuum with a crevice attachment is a great way to reach into the crevices and nooks and get rid of any dust, dirt or other debris that may have accumulated.

The coils require to be cleaned. Be sure to have a few essential tools on hand before you begin. This will include a coil cleaner concentrate and a pump-up garden hose and a garden hose. Spray the coil cleaner in accordance with the directions on the label, then rinse with the garden hose. When washing the coils it is important not to apply too much force as the fins can bend easily.

It is recommended to inspect the coils for signs of damage after cleaning. Over time hail, stones thrown by lawnmowers, and other things can harm the coil’s fins. Fin combs are a great way to straighten bent fins for better airflow and performance of the coil.

Once you have a good coil and fin set up and you are ready to turn on your air conditioner. Check the thermostat every 24 hours to ensure temperatures are within the normal range.

Clean the Ductwork

Your HVAC system is able to bring air in from outside, cooling it and distributing it throughout the home. The air moves from the evaporator coil of the condenser unit to your home’s vents and registers through a network of ducts. These ducts may become clogged with dust and other pollutants if they are not cleaned and sealed properly. This can block the air filters which reduces the efficiency of your system and burdens your AC unit.

In most instances, cleaning ductwork is not an easy task and requires professional equipment and methods. But, there are things you can do regularly to make sure your ducts are in good condition and function properly. First, you should change your filter on a regular basis to prevent dust and allergens out of building up in the ducts. This can also help prevent clogging, which can cause a decrease in efficiency and a higher cost for energy.

Vacuuming the area around the vent openings is another way to keep your ducts cleaner. The hose attachment of your vacuum cleaner will get rid of all the crumbs, cobwebs and other debris that has accumulated over time. This will improve airflow through the vent. You should also make sure that your ducts are sealed tightly and are insulated to prevent moisture from getting in, which could lead to mold and other biological contaminants.

Ducts that are not cleaned on a regular basis can be filled with a myriad of contaminants, such as dust, pet dander and pollen. These particles can cause allergies and respiratory issues especially for children and the elderly. In addition, moisture in ductwork may cause the growth of mold, which releases spores into air and poses health concerns for those suffering from respiratory ailments.

It is recommended to clean your ducts every three to five years to eliminate these contaminates and ensure that your HVAC system is functioning efficiently. However If your ducts are sealed and you regularly change your filters the cleaning of your ducts may not be required at all. You can only be sure by having your ducts examined. A contractor accredited by the EPA can employ specific testing methods to determine the amount of particles that are present in your ductwork. They will then suggest cleaning schedules that are appropriate for your particular situation.

Check the Compressor

The compressor is a crucial component of the system. It has to be able to deliver cool air into the ducts. If the compressor isn’t working in the way it should, it can affect your productivity and cause the equipment to shut down. However, preventive maintenance can assist in identifying issues that are minor and help avoid prolonged downtime. Conducting these regular checks can also save you money by ensuring that your equipment is in good condition for as long as it is possible.

The most common sign of a compressor issue is a loss in cooling capacity, but this could be caused by a number of different factors. One possibility is that a compressor could be working too hard due to poor airflow. This could wear out the bearings and reduce the lifespan of the compressor. Another issue that is common is a blocked filter. Filters that have become blocked can restrict airflow and cause the compressor to overheat. To prevent this, it is crucial to clean or replace the filters on a regular basis, based on the recommendations of the manufacturer.

In addition, a clogged filter could also cause rattling noises in the compressor. This could be a sign that the bearings need to be changed. Regularly replacing pulleys and belts is an excellent idea. A pulley or belt that is loose could cause the compressor to overheat, causing other problems. It is also a good idea to drain your compressor on a regular basis. This will help remove moisture that can corrode the motor and other components. A professional service team can check for air leaks in the hoses, and ensure an adequate seal between the compressor and pressure switch.

Lastly, a puddle of water near the compressor could be a sign of a leak in the refrigerant. This is a serious issue that needs to be addressed immediately. If you suspect that there is a leak, shut off the air compressor. Consult a professional.

Check the Thermostat

The thermostat is kind of like the boss of your HVAC system, so it’s not surprising that it’s the first thing a technician will check when trouble occurs. It’s also one of the most often neglected maintenance items, but an appropriately maintained thermostat is vital to ensure your HVAC system’s proper operation. Common indicators that your thermostat requires periodic inspections include incorrect temperature readings, non-responsive controls, or constant cycling.

Inaccurate Temperature Readings

Thermostat sensors may become dirty over time, which may cause the device to display incorrectly. You can prevent these issues by ensuring the accuracy of your thermostat with the use of a separate thermometer.

A malfunctioning sensor or calibration may result in your system constantly switching off and on, which 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 fixed with simply replacing the thermostat’s batteries or resetting its breaker.

If your system isn’t responding to your thermostat in any way, it’s recommended to examine the breakers that regulate the thermostat and your HVAC equipment. If the breaker has been tripped, it will require resetting in order for the thermostat to connect with the system again.

It is also essential to examine your thermostat for signs of wear or damage. Look for evidence of dust or dirt and ensure that the thermostat isn’t overly exposed to sunlight. Finally, the fan blades should be checked for any signs of damage or 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 can.

Basic HVAC maintenance is a great strategy to cut down on energy costs and maintain comfort in your commercial space. It also increases the lifespan of cooling and heating equipment. By identifying issues with your thermostat, resetting the breaker, and replacing the batteries and fuses, you’ll be able keep your building comfortable all year round. Be sure to call a professional if you are having other issues or aren’t sure what’s the issue with your system.
