The Importance of HVAC Maintenance
When it is about your heating and cooling system, maintenance is the best way to avoid costly repairs or premature replacement. Most HVAC companies offer a service plan where you pay each month to have the system inspected and cleaned or repaired when needed.
It is also recommended to perform DIY maintenance throughout the year. Cleaning or replacing air filters, and keeping the area around outdoor units free of clutter will help ensure proper airflow.
Clean the Condenser
The coils in your air conditioner’s condenser are the core of the cooling process. If they’re dirty, your system will struggle to cool, and it could even breakdown. Cleaning them is a vital component of HVAC maintenance. It’s fairly easy to accomplish. This simple DIY task can prevent the need for expensive repairs, save you money on your energy bills and prolong the longevity of your AC unit.
First and foremost, it is crucial to shut off the power supply to your unit. This can be done by shutting 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.
Once the power is off it is now time to clear any large debris obstructing the air condenser unit. This means sweeping up any leaves, sticks, or other debris that has accumulated on or around the unit. Using a shop vacuum with crevice attachments is a great way to get into the crevices and nooks and loosen any dirt, dust or other debris that may have accumulated.
The coils need to be cleaned. Before you do this however, make sure that you have in your possession some essential tools. Included in this are a coil cleaning concentrate as well as a pump-up garden sprayer as well as the garden hose. Spray the coil cleaner in accordance to the instructions on the label, and then rinse with the hose. It is important not to use too much pressure when washing the coils, because the fins may be bent.
You should examine the coils for signs of damage following cleaning. Over time hail and stones thrown by lawnmowers, and other things can harm the coil’s fins. If the fins are bent, an affordable tool called a fin comb can straighten them for better air flow and assist in ensuring that the coils operate more efficiently.
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 home and switch on your air conditioner. Check the thermostat every 24 hours to make sure temperatures are within the normal range.
Clean the Ductwork
Your HVAC system is able to bring outside air into your home, cool it, and then distribute it throughout the home. The air is moved from the evaporator coil of the condenser unit to the vents and registers of your home through a network of ducts. These ducts can become clogged with dust and other pollutants when they aren’t cleaned and sealed correctly. This can block the air filters and reduces system efficiency and strains your AC unit.
In most cases, cleaning the ductwork is not an easy task and requires expert equipment and techniques. There are a few things you can do to keep your ducts clean and in good working order. To stop dust and allergens accumulating in the ducts, you should change your filter on a regular basis. This can also help prevent clogging, which can result in a decrease in system efficiency and a higher cost for energy.
Another way to help keep your ducts clean is to regularly cleaning the area around vent openings. The hose attachment on your vacuum cleaner will take away all traces of dust, crumbs and other debris that has accumulated over time. This will increase the flow of air through the vent. It is also important to ensure that your ducts are sealed well and are insulated to prevent moisture from getting in, which could cause mold and other biological contaminants.
Ducts that have not been regularly cleaned are likely to be contaminated with a variety of contaminants, such as dust, pet dander and pollen. These particles can trigger allergies and respiratory conditions particularly for older people and children. Moisture can also cause mold to develop in ductwork, which releases spores that are harmful to those with respiratory problems.
It is recommended that you clean your ductwork every three to five year to get rid of these toxins and ensure that your HVAC system is functioning efficiently. If your ducts are sealed properly, and you regularly change your filter, it may not be necessary to clean them. The best way to determine the truth is to have your ducts tested. A contractor that is certified by the EPA can use special testing methods in order to determine the amount of particles present in your ductwork. They will then recommend cleaning schedules that are appropriate for your particular situation.
Check the Compressor
The compressor is an essential component of the system. It needs to operate properly to provide cool air to the ducts. If the compressor isn’t operating as it should it could affect your productivity and cause equipment downtime. However, preventive maintenance can assist in identifying issues that are minor and avoid excessive downtime. Conducting these regular checks can also help you save money by keeping your unit in good shape for as long as is possible.
A decrease in cooling capacity is a typical indication of a problem with a compressor. This could be caused by several different factors. One possibility is that the compressor may be overworking because of poor airflow. This could cause the bearings to wear out and decrease the life of the compressor. A clogged air filter is another frequent problem. If the filter has become clogged it could reduce the airflow to the compressor and lead to overheating. It is crucial to clean or replace the filters in accordance with the manufacturer’s guidelines.
A blocked filter could cause a rattling sound in the compressor. This could indicate that the bearings are wearing out and need to be replaced. Regularly replacing the belts and pulleys is recommended. A pulley or belt that is loose can slip, causing the compressor to overheat and cause other issues. It is also a good idea to drain the compressor on a regular basis. This will get rid of the moisture that could cause corrosion to the motor and other parts. A professional service team will check for leaks in the hoses, and an adequate seal around the compressor and pressure sensor.
A pool of water in the vicinity of the compressor could be an indication of a leak in the refrigerant. This could be a dangerous problem that should be addressed immediately. If you suspect that there is a leak, shut off the air compressor and call a professional.
Check the Thermostat
It’s not too surprising that a technician will look at the thermostat first when there’s a problem. It’s also one of the most often neglected maintenance items, yet an appropriately maintained thermostat is vital to ensure your HVAC system’s optimal operation. The most common signs that your thermostat requires periodic inspections include incorrect temperature readings, ineffective controls, or constant cycling.
Inaccurate Temperature Readings
Over time the sensors on your thermostat will get dirty. This can cause it to display inaccurately. You can avoid this issue by checking the accuracy of your thermostat using a a separate thermometer.
A defective sensor or a flawed calibration could cause your system to turn off and on in a continuous manner. This is known as short cycling. This can have a negative impact on your comfort and result in unnecessary wear and tears on the compressor. The problem can be fixed by replacing the batteries in the thermostat or resetting the breaker.
If your system isn’t responding to your thermostat at all it’s a good idea to check the breakers that control both the thermostat as well as your HVAC equipment. If the breaker has tripped, it will require resetting to allow the thermostat to communicate with the system once more.
It’s also crucial to examine your thermostat for any signs of wear or damage. Examine for dust or dirt and ensure that the thermostat isn’t excessively exposed to the sun. Check 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 possible.
Basic HVAC maintenance is a great method to reduce energy costs and maintain comfort in your commercial space. It can also prolong the lifespan of cooling and heating equipment. It is possible to keep your building comfortable throughout the year by identifying problems with your thermostat, resetting your breaker and changing your batteries. Remember to call a professional if you are having other issues or unsure of what is going on with your system.
