The Importance of HVAC Maintenance
Maintenance is key when it comes to heating and cooling systems. It can help you avoid costly repairs or premature replacement. Most HVAC companies offer a service plan where you pay an affordable monthly fee to have the system checked out, fixed or cleaned if necessary.
It’s also an excellent idea to carry out a few DIY maintenance tasks throughout the year. These include cleaning or replacing air filters and keeping the space around outdoor units free of clutter to allow for proper airflow.
Clean the Condenser
The coils of your air conditioner condenser are at the heart the cooling process. If they’re dirty, you system will struggle to cool and could even fail. Cleaning them is a vital part of HVAC maintenance. It’s relatively simple to do. This easy DIY task will eliminate the need for costly repairs, and save you money on your energy bills, and prolong the lifespan of your air conditioning unit.
In the beginning, it is essential to cut off the power source to your unit. This can be done by shutting off the breaker at your electrical box, or the outdoor unit disconnect switch. This will prevent your electrical components and motors from being over-saturated when cleaning.
After the power is off, you can start taking down any large debris that could be blocking the air condenser. This means sweeping up any leaves, sticks, or other debris that has built up around or on the unit. Utilizing a shop vacuum that has a crevice attachment is a great option to get into the nooks and crevices and loosen any dirt, dust or other debris that has accumulated.
The next step is to clean the coils. Make sure you have the necessary tools available before you begin. Included in this are coil cleaning concentrates, a pump up garden sprayer, and the garden hose. Spray the coil cleaner according to the directions on the product’s label and then rinse it off using the hose. It is crucial not to apply too much pressure when washing the coils, since the fins could easily be bent.
After the coils have been cleaned, you should look them over for any indications of damage. Over time, hail and rocks thrown from lawnmowers or other items can damage coil fins. Fin combs can be utilized to straighten bent fins for better airflow and performance of the coil.
When the fins and coils are in good condition If you are satisfied with the condition of your fins and coils, return to your house and start your air conditioning. Check the thermostat every 24 hours to make sure temperatures are within the normal range.
Cleaning the Ductwork
Your HVAC system works by bringing air from outside, cooling it and distributing it throughout the home. The air moves from the evaporator coil of your condenser unit to your home’s vents and registers through a network of ducts. These ducts can become clogged with dust and other contaminants when they aren’t cleaned and sealed correctly. This can clog the air filters which can reduce the effectiveness of your system and can strain your AC unit.
In most instances, cleaning ductwork isn’t an easy task and requires the help of professional equipment and techniques. However, there are some actions you can take regularly to ensure that your ducts are in good condition and function properly. First, make sure you change your filter regularly to keep dust and allergens from building in the ducts. This can also help stop the clogging that could lead to reduced system efficiency and a high energy bill.
Vacuuming the area around the vent openings is another way to keep your ducts clean. Utilizing the hose attachment of your vacuum cleaner, you can eliminate all cobwebs and crumbs that accumulate over time, and assist in improving air flow through the vent. It is also essential to ensure that your ducts are sealed and sealed with insulation to keep out moisture which can cause mold and other biological contaminants.
If ducts are not regularly cleaned, they may build up a myriad of contaminants such as dust, pet dander, and pollen. These particles can exacerbate allergies and respiratory issues especially in children and the elderly. Moisture in ductwork can also result in the growth of mold which releases spores into air and poses health concerns for those who suffer from respiratory problems.
It is generally recommended that you have your ductwork cleaned every three to five years in order to eliminate these contaminates and ensure that your HVAC system functions efficiently. If your ducts are sealed well and you replace your filter on a regular basis, it may not be necessary to clean them. The best way to determine for sure is by having your ducts tested. A contractor that is certified by the EPA can use specific testing methods to determine the amount of particulates present in your ductwork. They will then suggest cleaning schedules that are appropriate for your particular situation.
Check the Compressor
The compressor is a crucial element of the system. It should be able provide cool air to the ducts. If the compressor isn’t operating properly, it can impact your productivity and cause interruption to your equipment. Fortunately, preventive maintenance can aid in identifying minor issues early and prevent unnecessary downtime. Performing these routine checks can also save you money by keeping your unit in good condition for as long as it is possible.
A decrease in cooling capacity is a common sign of a problem with a compressor. This could be caused by a variety of factors. A compressor could be working too hard due to poor airflow. This can cause wear on the bearings and diminish the lifespan of the compressor. Another common problem is a clogged filter. Filters that are clogged can hinder airflow and cause the compressor to overheat. To avoid this, it is important to clean or replace the filters regularly based on the manufacturer’s recommendation.
A blocked filter may also cause a rattling sound in the compressor. This could be an indication that the bearings need to be changed. Regularly replacing belts and pulleys is an excellent idea. A loose pulley or belt can cause slippage and cause compressor overheating and other problems. It is also a good idea to drain the compressor on a regular basis. This will remove moisture that can cause corrosion to the motor and other parts. A professional service team can also look for air leaks in the hoses and a tight seal between the compressor and the pressure switch.
A puddle of liquid close to the compressor could be an indicator of a leak. This could be a risky issue that needs to be addressed right away. If you suspect that there is a leak, turn off the air compressor. Consult a professional.
Check the Thermostat
It’s not surprising that a technician will always look at the thermostat first when there’s any issue. It’s also among the most commonly overlooked maintenance items, yet a properly maintained thermostat is crucial for ensuring your HVAC system’s optimal operation. The most common signs that your thermostat needs an inspection include inaccurate temperature readings, ineffective controls, or continuous cycling.
Inaccurate Temperature Readings
Thermostat sensors may become dirty over time, which could cause the thermostat to display incorrectly. Monitoring your thermostat’s accuracy regularly by using a separate thermometer can assist you in avoiding these issues and save energy.
A malfunctioning sensor, or a faulty calibration can cause your system to turn off and on in a continuous manner. This is called short cycling. This can adversely affect your comfort and result in unnecessary wear and tear to the compressor. These issues can be resolved by replacing the batteries in the thermostat or resetting the breakers.
Make sure you check the breakers on both your HVAC and thermostat in the event that your HVAC equipment doesn’t respond to your thermostat. If the breaker has tripped, it will need to be reset in order for the thermostat to be able to communicate with the system once more.
Check your thermostat for signs of wear and damage. Examine for dust or dirt and make sure that the thermostat isn’t too much exposed to sunlight. The fan blades should be checked for any indications of rust or damage. This simple check will help avoid costly repairs in the future and ensure that your equipment operates as smoothly as possible.
Conducting basic HVAC maintenance on your commercial property is an excellent method to cut the cost of energy, maintain comfort and prolong the lifespan of your heating and cooling equipment. By identifying any issues with your thermostat, resetting the breaker, and replacing the batteries in the process, you’ll be able keep your building comfortable all year round. Be sure to call a professional if you are having other issues or aren’t sure what’s wrong with your system.
