The Importance of HVAC Maintenance
Maintenance is crucial when it concerns cooling and heating systems. It will allow you to avoid costly repairs or premature replacement. The majority of HVAC companies offer a service plan that allows you to pay each month to have the system inspected and cleaned or repaired when needed.
It’s also an excellent idea to carry out some DIY maintenance tasks throughout the year. This includes cleaning or replacing air filters and keeping the area around outdoor units free of any debris to ensure the proper flow of air.
Clean the Condenser
The coils of your condenser for your air conditioner are at the heart the cooling process. If they are dirty the system will be unable to cool properly and could even fail. Cleaning them is a vital aspect of HVAC maintenance. It’s fairly easy to accomplish. This easy DIY task will eliminate the need for costly repairs, save you money on your energy bills, and prolong the lifespan of your air conditioning unit.
First and foremost, it is essential to cut off the power supply to your unit. This can be done by turning off the breaker in the electrical box, or by turning off the outdoor unit disconnect switch. This will prevent your motors and other electrical components from becoming oversaturated when cleaning.
After the power has been shut off, you can begin to clear any large debris obstructing the air condenser unit. This means sweeping up any sticks, leaves, or other debris that has built up around or on the unit. Using a shop vacuum with a crevice attachment is a great way to get into the nooks and crevices and get rid of dust, dirt or other debris that has collected.
The next step is to clean the coils. Make sure you have some essential tools on hand before you start. Included in this are coil cleaning concentrates and a pump-up garden sprayer as well as the garden hose. Spray the coil cleaner on in accordance with the directions on the label of the product and then rinse using the hose. It is crucial not to apply too much pressure when washing the coils, because the fins may be bent.
After the coils have been cleaned, look them over for any signs of damage. Over time hail or stones thrown by lawnmowers, and other items can damage the coil’s fins. Fin combs can be used to straighten bent fins for better airflow and performance of the coil.
After you have a proper coil and fin set up, you can switch on your air conditioner. After about 24 hours, you can check the thermostat and make sure that temperatures are normal.
Clean the Ductwork
Your HVAC system is able to bring air from outside into your home, cool it and then distribute it throughout the home. Air is moved from the evaporator inside your condenser to your home’s registers, vents, and registers by the system duct. If these ducts aren’t cleaned and sealed, they could be laden with dirt and other contaminates. This could block air filters, which decreases the efficiency of your system and strains your AC unit.
Cleaning the ductwork can be a challenging task that requires professional equipment and methods. There are some things you can do to keep your ducts tidy and in good working order. To stop dust and allergens accumulating in the ducts, change your filter frequently. This can also help keep the clogs from occurring which can cause a decrease in system efficiency and high energy bills.
Another method to keep your ducts clean is by regularly cleaning the area around the vent openings. Using the hose attachment on your vacuum cleaner, you can eliminate all cobwebs and crumbs which accumulate over time, and aid in improving airflow through the vent. It is also important to ensure that your ducts have been sealed tight and lined to stop moisture from entering, which can result in mold and other biological contaminants.
Ducts that have not been regularly cleaned can be filled with a wide variety of contaminants, such as dust, pet dander and pollen. These particles can trigger respiratory issues and allergies, especially for older people and children. Moisture can also cause mold to grow in the ductwork, releasing the spores that can be harmful to those suffering from respiratory ailments.
It is generally recommended that you have your ductwork cleaned every three to five years to eliminate these contaminates and ensure that your HVAC system functions effectively. If your ducts have been sealed well and you replace your filter on a regular basis, it may not be necessary to clean them. You can be certain that your ducts are in good condition by having them checked. A contractor accredited by the EPA can use special testing techniques to determine the amount of particles that are present in your ductwork. They will then suggest cleaning schedules that are appropriate for your situation.
Check the Compressor
The compressor is a crucial component of the system. It should be able deliver cool air into the ducts. If the compressor isn’t operating as it should, this can impact the efficiency of your business and lead to interruption to your equipment. Fortunately, preventive maintenance can aid in identifying minor issues early and avoid excessive downtime. These routine checks will also save you money by ensuring that your equipment as efficient as possible.
A reduction in cooling capacity is a common sign of a problem in a compressor. This could be caused by a variety of factors. A compressor may be operating too hard due insufficient airflow. This can wear out the bearings and decrease the life of the compressor. Another common problem is a clogged filter. Filters that are clogged can restrict airflow and cause the compressor to overheat. It is essential to clean or replace the filters in accordance with the manufacturer’s instructions.
A clogged filter may also cause a rattling sound in the compressor. This could indicate that the bearings require to be changed. It is recommended to replace pulleys and belts regularly. A pulley or belt that is loose can slip, causing the compressor to overheat and create other problems. It is also a good idea to drain your compressor frequently. This will help remove moisture that can corrode the motor and other components. A professional service team will look for leaks in the hoses, and an adequate seal around the pressure sensor and compressor.
Lastly, a puddle of water near the compressor could be an indication of a leak in the refrigerant. This is a risky problem that must be dealt with immediately. If you suspect that there is a leak, turn off the air compressor and call a professional.
Check the Thermostat
The thermostat is kind of like the head of your entire HVAC system, so it’s not surprising that it’s the first thing that a technician will inspect when a problem occurs. A properly maintained thermostat is vital to the efficient operation of your HVAC system. It’s one of the most frequently neglected maintenance items. The most common signs that your thermostat is in need of periodic inspections include incorrect temperature readings, unresponsive controls, or continuous cycling.
Inaccurate Temperature Readings
Over time the sensors on your thermostat can get dirty. This can cause it to display inaccurately. You can avoid these problems by ensuring the accuracy of your thermostat with the use of a separate thermometer.
A faulty sensor or calibration may cause your system to keep turning on and off that is known as short cycling. This could have a negative effect on your comfort as well as cause unnecessary wear and tears on the compressor. Fortunately the majority of these issues can be resolved with the simple act of replacing the thermostat’s batteries or resetting the breakers.
Check the breakers for your thermostat and HVAC equipment in the event that your HVAC equipment doesn’t respond to your thermostat. If the breaker has tripped it, you’ll need to reset it to allow your thermostat to reconnect with the system.
It’s also crucial 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. Examine the fan blades for signs of rust and damage. These simple checks will help prevent costly repairs in the future, and ensure your equipment is running as smoothly as it is possible.
Basic HVAC maintenance is a great method to cut down on energy costs and maintain comfort in your commercial building. It will also extend the life of your cooling and heating equipment. By identifying problems with your thermostat, setting the breaker and replacing the batteries in the process, you’ll be able keep your building cool all year. Make sure to contact an expert if you’re experiencing any other issues or are unsure of what’s going on with your system.
