The Importance of HVAC Maintenance

When it concerns your heating and cooling system, routine maintenance is the key to avoiding costly repairs or early-than-necessary replacement. Most HVAC companies offer a service plan where you pay each month to have the system checked, repaired or cleaned as required.

It is also recommended to perform DIY maintenance throughout the year. These include cleaning or replacing air filters, and keeping the space around outdoor units free of any debris to ensure proper airflow.

Clean the Condenser

The coils in the condenser in your air conditioner are the mainstay of the cooling process. If they are dirty, your system is likely to struggle to cool and could even fail. Cleaning them is a crucial part of HVAC maintenance. Fortunately, it is also quite simple to do. This easy DIY task will save you money, prevent expensive repairs and extend the life of your air conditioner.

It is essential to disconnect power from your unit first. This can be done by shutting off the breaker inside the electrical box, or by turning off the outdoor unit disconnect switch. This will protect your electrical components and motors from being over-saturated during cleaning.

Once the power is off and you are able to remove any large debris blocking the air condenser unit. This means sweeping up any sticks, leaves, or other debris that has accumulated around or on the unit. A shop vacuum with crevice tools is a great tool to get into the nooks and crannies, and loosen dust or dirt that has built up.

Next, it is time to clean the coils. Before you begin however, ensure that you have in your possession several essential tools. Included in this are coil cleaning concentrates and a pump-up garden sprayer and an outdoor hose. Spray the coil cleaner in accordance to the instructions on the label, then rinse it off using the hose. When washing the coils, it is essential not to use too much force as the fins are easily bent.

You should examine the coils for signs of damage following cleaning. Over time, hail and rocks that are thrown by lawnmowers and other items could damage 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 help the coils function more efficiently.

If the fins and coils are in good condition If you are satisfied with the condition of your fins and coils, go back to your home and turn on your air conditioning. Check the thermostat every 24 hours to make sure temperatures are within the normal range.

Clean the Ductwork

Your HVAC system works to bring outside air into your home, cool it, and then distribute it throughout the home. The air is moved from the evaporator coil of the condenser unit to the vents and registers of your home through a system of ducts. If these ducts aren’t cleaned and sealed, they can become clogged with dust and other contaminants. This could block air filters, which decreases the effectiveness of your system and burdens your AC unit.

In most instances, cleaning ductwork is not an easy job and requires professional equipment and methods. There are some actions you can take regularly to keep your ducts clean and in good working order. To prevent dust and allergens from accumulating in the ducts, it is recommended to change your filter regularly. This will also help prevent clogging, which can cause a decrease in efficiency and higher energy bills.

Vacuuming the area around the vent openings is another method to keep your ducts clean. Utilizing the hose attachment of your vacuum cleaner can remove all of the dust and crumbs that build up over time and help to improve airflow through the vent. Also, make sure that your ducts have been sealed tight and insulated to prevent moisture from getting in, which could lead to mold and other biological contaminants.

If ducts are not cleaned regularly, they could build up a myriad of contaminants like dust, pet dander, and pollen. These particles can exacerbate allergies and respiratory conditions particularly in children and the elderly. Moisture can cause mold to grow in the ductwork, which releases the spores that can be harmful to those suffering from respiratory ailments.

It is recommended to 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 are well-sealed, and you change your filter regularly it might not be necessary to clean them. The best way to be able to tell for sure is by having your ducts tested. 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 recommend cleaning schedules that are appropriate for your specific situation.

Check the Compressor

The compressor is an essential component of the system. It must be able to provide cool air to the ducts. If the compressor isn’t working properly, it can impact the efficiency of your business and lead to downtime for equipment. Preventive maintenance can help identify small issues early, preventing excessive downtime. These regular checks will also save you money by ensuring that your equipment in the best condition possible.

A loss of cooling capacity is a common sign of a problem in the compressor. It could be caused by a variety of reasons. One possibility is that a compressor may be overworking because of poor airflow. This could cause the bearings to wear out and reduce the lifespan of the compressor. A clogged air filter is another common problem. If the filter has become clogged it can impede airflow to the compressor, which can cause overheating. It is crucial to clean or change the filters according to the manufacturer’s recommendations.

A blocked filter can cause a rattling sound in the compressor. This could mean that the bearings are wearing out and require to be replaced. It is recommended to replace belts and pulleys regularly. A loose belt or pulley can slip, causing the compressor to overheat and create 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, and an adequate seal around the compressor and pressure sensor.

Finally, a puddle of water near the compressor can be a sign of a leak in the refrigerant. This could be a dangerous problem that must be dealt with immediately. If you suspect that there is a leak, shut off the air compressor. Get a professional to assist you.

Check the Thermostat

The thermostat is kind of like the head of your HVAC system, and it’s not a surprise 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 overlooked maintenance items. Common signs that your thermostat needs a check-up include incorrect temperature readings, ineffective controls, or continuous cycling.

Inaccurate Temperature Readings

Over time, the thermostat’s sensors can get dirty. This could cause it to display inaccurately. You can avoid these problems by checking the accuracy of your thermostat by using a the use of a separate thermometer.

A defective sensor or a faulty calibration can cause your system to cycle on and off constantly. This is called short cycling. This can affect your comfort and cause unnecessary wear and tear on the compressor. The problem can be fixed by replacing the thermostat’s batteries or resetting the breakers.

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

It is also essential 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. Check the fan blades for evidence of damage or rust. These simple checks can help avoid expensive repairs in the future, and will ensure that your equipment is operating as smoothly as possible.

Performing basic hvac maintenance on your commercial property is an excellent method to cut energy consumption, ensure comfort and extend the lifespan of your cooling and heating equipment. By identifying issues with your thermostat, setting the breaker, and then replacing the batteries, you’ll be able to keep your building warm all year. Make sure that should you encounter any other issues, or are unsure of the issue, always call in a professional.
