The Importance of HVAC Maintenance

Maintenance is crucial when it concerns heating and cooling systems. It can 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 the system inspected, repaired or cleaned as required.

It’s also an excellent idea to carry out some DIY maintenance tasks throughout the year. These include 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 in your air conditioner are the mainstay of the cooling process. If they’re dirty, your system will struggle to cool, and it could even fail. Cleaning them is an important component of HVAC maintenance. It’s fairly easy to complete. This simple DIY task will save you money, prevent costly repairs, and increase the life of your air conditioner.

In the beginning, it is important to disconnect the power source to your unit. This can be done by turning off the breaker in your electrical box or by turning off the outdoor unit disconnect switch. This will safeguard your electrical components and motors from being over-saturated when cleaning.

After the power has been shut off it is now time to remove any large debris that is blocking the air condenser unit. This includes sweeping away any leaves, sticks or other debris that has been accumulating on or around the unit. A shop vacuum that has a crevice tool is a great tool to get into the crevices, nooks, and loosen dust or dirt that has accumulated.

Next, it is time to clean the coils. Before you begin, though, make sure you have a few key tools. Included in this are coil cleaning concentrates and a pump-up garden sprayer, and the garden hose. Spray the coil cleaner in accordance to the directions on the label, then rinse with the hose. When washing the coils it is essential not to use excessive force since the fins are easily bent.

It is recommended to inspect the coils for signs of damage following cleaning. Over time, hail or rocks thrown by lawnmowers and other items can damage the coil’s fins. Fin combs can be used to straighten bent fins to ensure better airflow and coil performance.

When the fins and coils are in good shape Once you’re satisfied with the condition of the fins and coils, you can return to your house and switch on your air conditioner. Check the thermostat every 24 hours to make sure temperatures are normal.

Clean the Ductwork

Your HVAC system works to bring outside air into your home, cool it, and then distribute it throughout your home. The air moves from the evaporator coil of the condenser unit to the vents and registers of your home through a system of ducts. These ducts can become clogged with dust and other contaminants when they aren’t maintained and sealed correctly. This causes air filters to become blocked which reduces the efficiency of your system and puts strain on your AC unit.

Cleaning ductwork can be a challenging task that requires expert equipment and techniques. There are some things you can do regularly to keep your ducts tidy and working well. To avoid dust and allergens from accumulating in the ducts, change your filter frequently. This will also help prevent clogging, which can lead to a reduced system efficiency and higher energy costs.

Another way to keep your ducts clean is to regularly cleaning the area around the vent openings. Using the hose attachment on your vacuum cleaner can remove all dust and crumbs that build up over time and help to improve air flow through the vent. Also, make sure that your ducts are sealed well and are protected from moisture entering, which can lead to mold and other biological contaminants.

If ducts aren’t regularly cleaned, they may collect a variety of pollutants such as dust, pet dander and pollen. These particles can exacerbate allergies and respiratory conditions particularly for older people and children. Moisture in ductwork can also cause the growth of mold, which releases spores in the air and poses health risks for those suffering from respiratory problems.

It is generally recommended to get your ductwork cleaned every three to five years to remove these contaminants and ensure your HVAC system is operating effectively. If your ducts have been well-sealed, and you regularly change your filter, it may not be necessary to clean them. You can only be sure by having your ducts examined. A contractor who is accredited by the EPA will use specific testing methods to determine the amount of particles 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 component of the system. It should be able supply cool air into the ducts. If the compressor isn’t operating properly, it can affect your productivity and cause downtime for your equipment. Regular maintenance can help you identify minor issues early, preventing unnecessary downtime. Regular checks can also save you money by ensuring that your equipment as efficient as possible.

A typical indication of a problem with a compressor is a reduction in cooling capacity, although it could be caused by a number of different factors. One possibility is that a compressor may be under-performing due to inadequate airflow. This can wear out the bearings and reduce the life of the compressor. Another common problem is a blocked filter. Filters that are blocked can restrict airflow and cause the compressor to overheat. It is crucial to change or clean the filters according to manufacturer’s guidelines.

A clogged filter may also cause rattling sounds in the compressor. This could be an indication that the bearings need to be changed. Regularly replacing pulleys and belts is recommended. A belt or pulley that is loose can slip and lead to overheating of the compressor and other issues. It is recommended 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 will also look for leaks in the hoses, as well as an adequate seal around the compressor and pressure sensor.

A puddle of liquid close to the compressor could be an indication of a leak. This could be a risky issue and should be repaired right away. If you suspect there is a leak, shut off the air compressor and call an expert.

Check the Thermostat

It’s not surprising that a technician will check the thermostat first when there is a problem. A well-maintained thermostat is vital to the proper operation of your HVAC system. It’s among the most frequently neglected maintenance items. Common signs that your thermostat needs an inspection include inaccurate temperature readings, unresponsive controls, or constant cycling.

Inaccurate Temperature Readings

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

A defective sensor or a wrong calibration, could cause your system to turn off and on constantly. This is called short cycling. This could have a negative effect on your comfort and result in unnecessary wear and tears on the compressor. Fortunately the majority of these issues can be corrected by the simple act of replacing the thermostat’s batteries or resetting the breaker.

Check the breakers for both your HVAC equipment and thermostat if your system doesn’t respond to your thermostat. If the breaker has tripped it, you’ll need to reset it in order for your thermostat to communicate again with the system.

Check your thermostat for indications of wear and tear. Look for signs of dirt or dust, and make sure the thermostat isn’t overly exposed to sunlight. Check the fan blades for evidence of damage or rust. These simple checks can help avoid costly repairs in the near future, and ensure your equipment is operating as smoothly as possible.

Basic HVAC maintenance is a great method to reduce energy costs and maintain comfort in your commercial property. It will also extend the lifespan of heating and cooling equipment. By identifying problems with your thermostat, resetting the breaker, and replacing the batteries, you’ll be able to keep your building cool all year. Be sure to call a professional should you encounter any other issues or are unsure about the issue you should always consult an expert.
