The Importance of HVAC Maintenance
Maintenance is key when it comes to cooling and heating systems. It will allow you to avoid costly repairs or premature replacement. Most HVAC companies offer a service plan where you pay an affordable monthly fee to have your system checked, fixed or cleaned when needed.
It’s also recommended to do some DIY maintenance tasks throughout the year. This includes cleaning or replacing air filters and keeping the space around outdoor units free of clutter to allow for the proper flow of air.
Clean the Condenser
The coils in the condenser in your air conditioner are the core of the cooling process. If they are dirty, your system will struggle to cool and could even breakdown. This is why cleaning them is a vital component of HVAC maintenance. It’s relatively simple to complete. This easy DIY task will save you money, prevent expensive repairs and extend the life span of your air cooling.
It is vital to cut off the power source from your unit first. This can be done by turning off the breaker in the electrical box, or by turning off the outdoor unit disconnect switch. This will stop your motors and other electrical components from getting overloaded during cleaning.
After the power is off, you can begin clearing any large debris that could be blocking the condenser air. This will include cleaning up 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, crannies, and loosen dust or dirt that has built up.
The coils need to be cleaned. Before you begin however, ensure that you have in your possession some essential tools. These include a coil cleaner concentrate and a pump-up garden sprayer and a garden hose. Spray the coil cleaner in accordance to the directions on the label, then rinse with the garden hose. It is crucial not to apply excessive pressure when washing the coils, because the fins may be bent.
After the coils have been cleaned, you should inspect them for any signs of damage. Over time, hail or rocks thrown by lawnmowers and other items can damage the coil’s fins. If the fins are bent, a low-cost tool called a fin comb can straighten them to improve air flow and assist in ensuring that the coils operate more efficiently.
If 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 turn on your air conditioning. After approximately 24 hours, you can examine the thermostat and make sure that the temperatures are in line with normal.
Cleaning the Ductwork
Your HVAC system is designed to bring outside air into your home, cool it, and then distribute it throughout the home. The air is moved from the evaporator coil in your condenser unit to your home’s vents and registers through a network of ducts. If the ducts aren’t cleaned and sealed, they may become loaded with dust and other pollutants. This clogs the air filters which reduces the efficiency of your system and strains your AC unit.
In the majority of cases, cleaning the ductwork is not an easy job and requires expert equipment and methods. There are a few actions you can take regularly to ensure that your ducts are clean and functioning properly. First, make sure you change your filter on a regular basis to keep dust and allergens out of building up in the ducts. This will also help to prevent the clogging that can cause a decrease in system efficiency and a high energy bill.
Another way to help keep your ducts tidy is to regularly cleaning the area around the vent openings. By using the hose attachment on your vacuum cleaner, you can eliminate all of the cobwebs and crumbs that accumulate over time, and will assist in improving airflow through the vent. Also, make sure that your ducts are sealed tight and lined to stop moisture from getting in, which could cause mold and other biological contaminants.
If ducts aren’t cleaned regularly, they could collect a variety of pollutants such as dust, pet dander, and pollen. These particles can cause a flare-up of respiratory issues and allergies particularly for children and the elderly. Moisture in ductwork can also lead to the growth of mold, which releases spores into air and can cause health issues for those suffering from respiratory problems.
It is recommended that you clean your ducts once every three to five years to remove these contaminants and ensure that your HVAC works efficiently. However If your ducts are sealed properly and you clean your filters frequently, duct cleaning may not be necessary at all. You can be certain by having your ducts examined. A contractor accredited by the EPA can employ special testing techniques to measure the amount particulates that are present in your ductwork. They will then recommend cleaning schedules that are suitable for your specific situation.
Check the Compressor
The compressor is a crucial component of the system. It should be able supply cool air into the ducts. If the compressor isn’t functioning as it should it could affect your productivity and result in the equipment to shut down. Fortunately, preventive maintenance is able to aid in identifying minor issues early and prevent unnecessary downtime. Conducting these regular checks can also save you money by ensuring that your equipment is in good condition for as long as it is possible.
A reduction in cooling capacity is a common sign of a problem with a compressor. It could be caused by a variety of factors. One possibility is that a compressor could be working too hard due to poor airflow. This can wear out the bearings and decrease the lifespan of the compressor. A clogged air filter is a different problem. If the filter is clogged it can impede airflow to the compressor and lead to overheating. It is crucial to clean or replace the filters according to the manufacturer’s recommendations.
A blocked filter can create a rattling sound inside the compressor. This could indicate that the bearings are worn out and require to be replaced. Regularly replacing pulleys and belts is an excellent idea. A worn-out belt or pulley can slip, causing the compressor to overheat and create other problems. It is also a good idea to drain the compressor regularly. This can remove accumulated 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 pressure sensor and compressor.
Lastly, a small puddle of water around the compressor can be an indication of a leak in the refrigerant. This could be a risky issue that needs to be addressed immediately. If you suspect there is a leak, switch off the air compressor and contact an expert.
Check the Thermostat
It’s not a surprise that technicians will always check the thermostat first when there’s a problem. It’s also one of the most commonly overlooked maintenance items, but maintaining your thermostat properly is essential to ensure your HVAC system’s optimal operation. Examine your thermostat if you find inaccurate temperature readings, ineffective controls or constant cycling.
Inaccurate Temperature Readings
Over time the thermostat’s sensors will get dirty. This could cause it to display in a wrong manner. You can prevent these issues by checking the accuracy of your thermostat with a separate thermometer.
A malfunctioning sensor or calibration may lead to your system continuously switching off and on that is known 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 breakers.
If your system isn’t responding to your thermostat at all it’s an excellent idea to look at the breakers that control both the thermostat as well as your HVAC equipment. If the breaker tripped, you will need to reset it to allow your thermostat to reconnect with the system.
Check your thermostat for indications of wear and damage. Look for signs of dirt or dust and ensure that the thermostat isn’t too exposed to sunlight. Examine the fan blades for evidence of damage or rust. These simple checks can prevent costly repairs in the future, and will ensure that your equipment is operating as smoothly as possible.
Conducting basic HVAC maintenance on your commercial property is a great way to reduce energy costs, maintain comfort and extend the life of your cooling and heating equipment. By identifying any issues with your thermostat, setting the breaker, and replacing the batteries and fuses, you’ll be able keep your building cool all year round. Remember to call an expert if you’re having other issues or unsure of what is wrong with your system.
