The Importance of HVAC Maintenance
Maintenance is essential when it concerns HVAC and cooling systems. It will help you avoid costly repairs or premature replacement. The majority of HVAC companies offer a maintenance plan where you pay an affordable monthly fee to get the system checked, repaired or cleaned when needed.
You should also perform some DIY maintenance throughout the year. Cleaning or replacing air filters, and keeping the area around outdoor units clear of clutter will help ensure the proper flow of air.
Clean the Condenser
The coils inside the condenser of your air conditioner are the mainstay of the cooling process. If they are dirty the system is likely to struggle to cool and could even fail. This is why cleaning them is a vital component of HVAC maintenance. Fortunately, it is also quite simple to do. This easy DIY task will eliminate the need for expensive repairs, and save you money on your energy bills, and prolong the longevity of your AC unit.
It is vital to cut off power from your unit first. You can do this by turning off the breaker at your electrical box, or by turning off the outdoor unit disconnect switch. This will keep your motors and other electrical components from becoming oversaturated during cleaning.
Once the power has been shut off, you can begin removing any large objects that could be hindering the air condenser. This includes sweeping off any sticks, leaves or other debris that have accumulated around or on the unit. A shop vacuum with a crevice tool is a great way to reach into the nooks and crannies and remove dirt or dust that has built up.
Next, it is time to clean the coils. Be sure to have the necessary tools on hand before you begin. These will include a concentrate for coil cleaning and a pump-up garden sprayer and a garden hose. Spray the coil cleaner on according to the directions on the product label and then rinse using the hose. When washing the coils it is important not to apply too much force as the fins can be bent easily.
After the coils have been cleaned, look them over for any indications of damage. Over time hail or stones thrown by lawnmowers, and other things can harm the coil’s fins. Fin combs are a great way to straighten bent fins to ensure better airflow and performance of the coil.
After you have a proper coil and fin set up, you can start your air conditioner. After around 24 hours, you can examine the thermostat to ensure that the temperatures are in line with normal.
Cleaning the Ductwork
Your HVAC system is able to bring air in from outside, cooling it, and distributing it throughout your home. The air moves from the evaporator coil of your condenser unit and then to the vents and registers of your home through a system of ducts. If these ducts aren’t cleaned and sealed, they can be laden with dust and other pollutants. This could block air filters, which decreases the effectiveness of your system and burdens your AC unit.
Cleaning the ductwork can be a challenging task that requires specialized equipment and methods. But, there are actions you can take on a regular basis to make sure your ducts remain clean and well-functioning. To avoid dust and allergens from accumulating in the ducts, it is recommended to change your filter frequently. This will also help to stop clogging, which could cause a decrease in efficiency and higher energy costs.
Cleaning the area around the vent openings is another method to keep your ducts cleaner. Utilizing the hose attachment of your vacuum cleaner can remove all of the cobwebs and crumbs which accumulate over time and assist in improving airflow through the vent. It is also important to ensure that your ducts are properly sealed and insulated to keep out moisture which can cause mold and other biological contaminants.
Ducts that aren’t regularly cleaned can become loaded with a myriad of pollutants, including dust, pet dander, and pollen. These particles can exacerbate allergies and respiratory problems especially for children and the elderly. The moisture in ductwork can lead to the growth of mold which releases spores into air and poses health risks for those suffering from respiratory ailments.
It is generally recommended that you get your ductwork cleaned every three to five years in order to eliminate these contaminates and ensure that your HVAC system functions effectively. 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 certain that your ducts are in good condition by having them checked. An accredited contractor can use special testing methods to measure the amount of particulates within your ductwork, and will recommend the appropriate cleaning schedules that are based on the specific circumstances.
Check the Compressor
The compressor is an essential element of the system. It should be able provide cool air to the ducts. If the compressor isn’t functioning in the way it should, this could affect the efficiency of your business and lead to downtime for equipment. Preventive maintenance can help identify small issues early, preventing unnecessary downtime. These routine checks will also save you money by keeping your unit as good as possible.
A reduction in cooling capacity is a typical sign of a problem in the compressor. It could be caused by several different factors. A compressor may be working too hard due to inadequate airflow. This could wear out the bearings and decrease the life of the compressor. A clogged air filter is a different problem. Filters that are clogged can hinder airflow and cause the compressor to overheat. It is essential to clean or replace the filters in accordance with the manufacturer’s instructions.
Additionally, a blocked filter can also cause a rattling sound in the compressor. This could be a sign that the bearings need to be replaced. It is also a good idea to replace belts and pulleys on a regular basis. A belt or pulley that is loose can slip and lead to compressor overheating and other problems. It’s also a good idea to drain your compressor frequently. This can remove accumulated moisture that can corrode the motor and other components. A professional service team will look for leaks in the pipes, and ensure an adequate seal around the pressure sensor and compressor.
A puddle of liquid close to the compressor could be a sign of an issue. This can be a dangerous issue and should be repaired immediately. If you suspect that there is a leak, shut off the air compressor. Contact a professional.
Check the Thermostat
The thermostat acts like the boss of your entire HVAC system, and 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, yet maintaining your thermostat properly is essential to ensure your HVAC system’s proper operation. The most common signs that your thermostat is in need of a check-up include incorrect temperature readings, ineffective controls, or continuous cycling.
Inaccurate Temperature Readings
Over time the thermostat’s sensors can become dirty. This could cause it to display inaccurately. You can prevent these issues by ensuring the accuracy of your thermostat by using a the use of a separate thermometer.
A malfunctioning sensor or calibration could cause your system to keep switching off and on, which is referred to as short cycling. This can affect your comfort, and cause excessive wear and tear on the compressor. The problem can be fixed by simply replacing the batteries in the thermostat or resetting the breaker.
Check the breakers for your HVAC equipment and thermostat if your system doesn’t respond to your thermostat. If the breaker has tripped then you’ll have to reset it in order for your thermostat to communicate again with the system.
It is also essential to examine your thermostat for signs of wear or damage. Look for dust or dirt and make sure that the thermostat isn’t too much exposed to sunlight. The fan blades must be inspected for signs of damage or rust. These simple checks can help avoid costly repairs in the near future, and will ensure that your equipment is operating as efficiently as it can.
Conducting basic HVAC maintenance on your commercial property is an excellent way to cut down on energy consumption, ensure comfort and prolong the lifespan of your heating and cooling equipment. By identifying problems with your thermostat, setting the breaker and replacing the batteries and fuses, you’ll be able keep your building cool all year. Remember to call a professional if you are having other issues or unsure of what is going on with your system.
