The Importance of HVAC Maintenance

Maintenance is essential when it is concerned with HVAC and cooling systems. It will help you avoid costly repairs or premature replacement. The majority of HVAC companies have a maintenance plan where you pay a monthly fee to have your system checked and cleaned, or repaired as required.

You should also perform some DIY maintenance 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 flow of air.

Clean the Condenser

The coils in your air conditioner’s condenser are the heart of the cooling process. If they’re dirty, your system will be unable to cool properly and could even fail. Cleaning them is an essential part of HVAC maintenance. It’s fairly easy to complete. This simple DIY task will save you money, avoid expensive repairs and extend the life span of your air conditioner.

First and foremost, it is crucial to shut off the power supply to your unit. This can be done by turning off the breaker inside your electrical box or by turning off the outdoor unit disconnect switch. This will stop your motors and other electrical components from becoming oversaturated when cleaning.

After the power has been turned off, you can start removing any large debris that could be blocking the condenser air. This will include taking away any sticks, leaves or other debris that has been accumulating on or around the unit. A shop vacuum equipped with crevice tools is a great tool to reach into the nooks and crannies, and loosen dirt or dust that has been accumulating.

Next, it is time to clean the coils. Before you begin, though, make sure that you have on-hand a few key tools. These will include a coil cleaner concentrate and a pump-up garden sprayer and a garden hose. Spray the coil cleaner according to the instructions on the product’s label and rinse with the hose. When washing the coils it is important to not use too much force since the fins are easily bent.

You should examine the coils for signs of damage after cleaning. Over time, the impact of hail and stones thrown from lawnmowers or other items can damage coil fins. Fin combs are a great way to straighten bent fins to ensure better airflow and performance of the coil.

When you have a great coil and fin setup, you can switch on your air conditioner. Check the thermostat after about 24 hours to confirm that temperatures are normal.

Cleaning the Ductwork

Your HVAC system works by bringing air from outside, cooling it, and distributing it throughout the home. The air travels from the evaporator coil of the condenser unit to the vents and registers of your home through a duct system. The ducts could become blocked with dust and other pollutants if they are not cleaned and sealed correctly. This causes air filters to become blocked and reduces the efficiency of the system and puts strain on your AC unit.

In the majority of instances, cleaning ductwork is not an easy task that requires expert equipment and techniques. However, there are some actions you can take regularly to make sure your ducts stay clean and functioning well. To avoid dust and allergens accumulating in the ducts, it is recommended to change your filter frequently. This will also help to keep the clogs from occurring which can lead to reduced system efficiency and higher energy costs.

Another way to help keep your ducts tidy is to regularly cleaning the area around the vent openings. Utilizing the hose attachment of your vacuum cleaner, you can eliminate all cobwebs and crumbs which accumulate over time and assist in improving airflow through the vent. It is also essential to make sure your ducts are properly sealed and insulated to keep out moisture, which can cause mold and other biological contaminants.

If ducts are not cleaned regularly, they can accumulate a variety of contaminants such as dust, pet dander, and pollen. These particles can trigger respiratory issues and allergies, especially for older people and children. Moisture can cause mold to grow in the ductwork, releasing microbes that can harm those suffering from respiratory ailments.

It is recommended that you clean your ductwork every three to five year to get rid of these toxins and ensure that your HVAC system is functioning efficiently. If your ducts have been 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 contractor that is certified by the EPA can use special testing techniques to measure the amount particulates found in your ductwork. They can then recommend cleaning schedules that are appropriate for your situation.

Check the Compressor

The compressor is an essential component of the system. It must be able to deliver cool air into the ducts. If the compressor isn’t functioning properly it could affect your productivity and cause equipment downtime. Preventive maintenance can help spot minor issues early, preventing excessive downtime. Performing these routine checks can also help you save money by ensuring that your equipment is in good working order for as long as possible.

A decrease in cooling capacity is a common sign of a problem in the compressor. This can be caused by a variety of causes. One possibility is that a compressor may be working too hard due to poor airflow. This can cause the bearings to wear out and reduce the lifespan of the compressor. Another common problem is a clogged filter. If the filter has become clogged it can impede airflow to the compressor and lead to overheating. To prevent this from happening, it is essential to clean or replace the filters frequently, according to the recommendations of the manufacturer.

A blocked filter can cause a sound of rattling in the compressor. This can indicate that the bearings are worn out and require to be replaced. It is recommended to replace pulleys and belts on a regular basis. A worn belt or pulley could cause slipping and result in compressor overheating and other issues. It is recommended to drain the compressor on a regular basis. This will get rid of moisture that can cause corrosion to the motor and other parts. A professional service team will examine for leaks in hoses, as well as an adequate seal around the pressure sensor and compressor.

Lastly, a puddle of water near the compressor can be an indication of a leak in the refrigerant. This can be a dangerous issue that needs to be addressed immediately. If you suspect that there is a leak, shut off the air compressor and contact an expert.

Check the Thermostat

The thermostat acts like the head of your HVAC system, so it’s not a surprise that it’s the first thing that a technician will inspect when a problem occurs. It’s also among the most often neglected maintenance items, yet a properly maintained thermostat is essential to ensure your HVAC system’s proper operation. Common signs that your thermostat is in need of a check-up include incorrect temperature readings, ineffective controls, or continuous cycling.

Inaccurate Temperature Readings

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

A malfunctioning sensor or calibration could cause your system to keep switching off and on this is known as short cycling. This can affect your comfort and result in unnecessary wear and tear on the compressor. This issue can be solved by simply replacing the thermostat’s batteries or resetting the breakers.

Check the breakers for your thermostat and HVAC equipment If your system isn’t responding to your thermostat. If the breaker has been tripped, it will have to be reset to allow the thermostat to communicate with the system once more.

It’s also crucial to examine your thermostat for signs of wear or damage. Find signs of dirt or dust and ensure that the thermostat isn’t overly exposed to sunlight. Examine the fan blades for signs of rust and damage. These simple checks can help avoid expensive repairs in the future, and will ensure that your equipment is operating as efficiently as it can.

Performing basic hvac maintenance on your commercial property is an excellent way to cut down on energy consumption, ensure comfort and prolong the longevity of your cooling and heating equipment. By identifying problems with your thermostat, setting the breaker, and then replacing the batteries in the process, you’ll be able keep your building warm all year round. Make sure that in case you experience any other issues or are unsure of what’s wrong with your system, always call in an expert.
