The Importance of HVAC Maintenance

When it concerns your heating and cooling system, maintenance is essential to avoid costly repairs or premature replacement. The majority of HVAC companies offer a maintenance plan that you pay a low monthly rate to get the system checked, fixed or cleaned if required.

It is also recommended to perform DIY maintenance throughout the year. Cleaning or replacing air filters and keeping the area surrounding outdoor units clear of debris will promote the proper flow of air.

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 could even fail. Cleaning them is an essential aspect of HVAC maintenance. It is relatively easy to accomplish. This easy DIY task will help you save money, avoid costly repairs and prolong the lifespan of your air cooling.

It is vital to cut off power from your unit before you disconnect it. This can be done by turning off the breaker in your electrical box or by turning off the outdoor unit disconnect switch. This will prevent your motors and electrical components from being oversaturated when cleaning.

After the power has been shut off, you can begin to clear any large debris that is obstructing the air condenser unit. This includes taking away any sticks, leaves or other debris that has accumulated on or around the unit. A shop vacuum that has crevice tools is a great way to reach into the nooks, crannies and remove dirt or dust that has built up.

The coils require to be cleaned. Before you do this however, ensure that you have on-hand a few key tools. This will include a concentrate of the coil cleaner and a pump-up garden sprayer and a garden hose. Spray the coil cleaner in accordance with the directions on the label, then rinse with a garden hose. It is crucial not to apply excessive pressure when washing the coils because the fins may be bent.

You should examine the coils for signs of damage after cleaning. Over time hail, stones thrown by lawnmowers, and other objects can cause damage to the coil fins. If the fins are bent, a cost-effective tool known as a fin comb can straighten them for better air flow and also to assist in ensuring that the coils operate more effectively.

Once you have a good coil and fin set up then you can turn on your air conditioner. After around 24 hours, you can check the thermostat and make sure that temperatures are normal.

Clean the Ductwork

Your HVAC system is able to bring air from outside into your home, cool it and then distribute it throughout your house. Air is transported from the evaporator of the condenser to your home’s registers and vents via a system of ducts. These ducts may become clogged with dust and other pollutants if they are not cleaned and sealed correctly. This can block the air filters, which in turn reduces system efficiency and puts strain on your AC unit.

In most cases, cleaning the ductwork isn’t an easy job and requires the help of professional equipment and techniques. There are some things you can do to ensure that your ducts are clean and in good working order. To prevent dust and allergens from building up in the ducts, change your filter regularly. This also helps to prevent the clogging that can result in a lower efficiency of the system and high energy bills.

Another way to keep your ducts clean is to regularly cleaning the area around vent openings. By using the hose attachment on your vacuum cleaner, you can get rid of all the dust and crumbs that build up over time and help to improve air flow through the vent. It is also important to ensure that your ducts are tightly sealed and sealed with insulation 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 cause allergies and respiratory issues particularly in children and the elderly. The moisture in ductwork can lead to the growth of mold which releases spores in the air and poses health concerns for those who suffer from respiratory problems.

It’s generally recommended that you get your ductwork cleaned every three to five years to remove these contaminants and ensure your HVAC system is operating efficiently. However, if your ducts are sealed and you clean your filters frequently it is possible that duct cleaning won’t be necessary at all. You can only be sure by having your ducts examined. An accredited contractor can use specific testing methods to determine the amount of particulates in your ductwork, and can recommend appropriate cleaning schedules based on your specific situation.

Check the Compressor

The compressor is an essential component of the system. It must function properly to provide cool air to the ducts. If the compressor isn’t functioning as it should, this could affect your productivity and result in interruption to your equipment. However, preventive maintenance can help catch minor issues early and avoid excessive downtime. These regular checks will also save you money by making sure that your equipment in the best condition possible.

The most common sign of a compressor problem is a decrease in cooling capacity, however this could be caused by a number of different factors. A compressor may be working too hard due insufficient airflow. This can cause bearings to wear down and reduce the lifespan of the compressor. A clogged air filter is another common problem. If the filter has become clogged, it can reduce the airflow to the compressor, which can cause overheating. To prevent this, it is crucial to clean or change the filters regularly based on the manufacturer’s recommendations.

A blocked filter could 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 regularly. A worn belt or pulley can cause slippage and cause overheating of the compressor and other issues. It is also a great idea to drain your compressor frequently. This will remove the accumulated moisture that can cause corrosion to the motor and other components. A professional service team can look for air leaks in the hoses, and ensure an adequate seal between the compressor and the pressure switch.

A puddle of water near the compressor could be a sign of a refrigerant leak. This could be a dangerous problem that should be addressed immediately. If you suspect that there is a leak, shut off the compressor that is running and then contact 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 that a technician will check when trouble arises. It’s also one of the most frequently neglected maintenance items, yet maintaining your thermostat properly is essential to ensure your HVAC system’s proper operation. Common signs that your thermostat requires an inspection include inaccurate temperature readings, non-responsive controls, or continuous cycling.

Inaccurate Temperature Readings

Over time the thermostat’s sensors may become dirty. This could cause it to display in a wrong manner. You can prevent these issues by regularly checking the accuracy of your thermostat with a separate thermometer.

A malfunctioning sensor, or a faulty calibration can cause your system to turn off and on constantly. This is called short cycling. This could have a negative effect on your comfort and cause unnecessary wear and tears on the compressor. Fortunately this can be corrected by the simple act of replacing the batteries in your thermostat or resetting its breakers.

If your system isn’t responding to your thermostat at all it’s recommended to examine the breakers that regulate the thermostat as well as your HVAC equipment. If the breaker has tripped, it will have to be reset in order for the thermostat to connect with the system again.

Check your thermostat for indications of wear and damage. Look for evidence of dust or dirt and ensure that the thermostat isn’t overly exposed to sunlight. Examine the fan blades for signs of damage and rust. These simple checks will help prevent expensive repairs in the future, and help ensure that your equipment is running as smoothly as it can.

Basic hvac maintenance is a great way to save energy and keep your comfort in a commercial building. It also increases the life of your cooling and heating 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. Make sure to contact a professional if you are experiencing any other issues or aren’t sure what’s going on with your system.
