The Importance of HVAC Maintenance
When it comes to your heating and cooling system, maintenance is the key to avoiding costly repairs or replacements that are not needed as soon as they should be. Most HVAC companies have a maintenance plan that allows you to pay a monthly fee to have your system checked and cleaned, or repaired as needed.
You should also perform some DIY maintenance throughout the year. This includes cleaning or replacing air filters and keeping the areas around outdoor units clear of clutter to allow for proper airflow.
Clean the Condenser
The coils in your air conditioner condenser 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 crucial aspect of HVAC maintenance. It’s fairly easy to complete. This easy DIY task can avoid the need for expensive repairs, and save you money on your energy bills and extend the lifespan of your air conditioning unit.
It is crucial to disconnect the power source from your unit first. This can be accomplished 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 being oversaturated when cleaning.
Once the power is off, you can begin clearing any large debris that may be hindering the condenser air. This means sweeping up any sticks, leaves, or other debris that has been accumulating on or around the unit. A shop vacuum with a crevice tool is a great way to reach into the nooks and crannies and remove dust or dirt that has built up.
The next step is to clean the coils. Before you do this however, ensure you have several essential tools. Included in this are coil cleaning concentrates as well as a pump-up garden sprayer as well as an outdoor hose. Spray the coil cleaner according to the instructions on the product label and then rinse it off using the hose. When washing the coils it is essential not to use too much force as the fins are easily bent.
You should examine the coils for signs of damage following cleaning. Over time, the impact of hail and stones dropped by lawnmowers or other objects can cause damage to coil fins. If the fins are bent, an affordable tool known as a fin comb can straighten them to improve air flow and assist in ensuring that the coils operate more effectively.
Once the coils and fins are in good condition If you are satisfied with the condition of your fins and coils, return to your house and switch on your air conditioning. After about 24 hours, you should check the thermostat and make sure that temperatures are normal.
Clean the Ductwork
Your HVAC system works by bringing air in from outside, cooling it and then distributing it throughout your home. Air is transported from the evaporator inside your condenser to your home’s registers and vents through a system ducts. If the ducts aren’t cleaned and sealed, they can become loaded with dust and other pollutants. This can block the air filters which reduces system efficiency and puts strain on your AC unit.
In the majority of instances, cleaning ductwork is not an easy task and requires the help of professional equipment and methods. However, there are a few actions you can take regularly to ensure your ducts stay clean and well-functioning. To prevent dust and allergens accumulating in the ducts, change your filter on a regular basis. This can also help stop clogging, which could result in a decrease in system efficiency and a higher cost for energy.
Cleaning the area around the vent openings is another way to keep your ducts in good shape. The hose attachment of your vacuum cleaner will get rid of all the crumbs, cobwebs and other debris that has built up over time. This will increase the flow of air through the vent. It is also important to make sure your ducts are properly sealed and sealed with insulation to keep out moisture, which can cause mold and other biological contaminants.
Ducts that have not been regularly cleaned can become loaded with a myriad of contaminants, such as dust, pet dander and pollen. These particles can cause allergies and respiratory issues particularly in children and the elderly. Moisture can cause mold to develop in the ductwork, which releases microbes that can harm those suffering from respiratory ailments.
It is recommended that you clean your ducts every three to five year to eliminate these contaminates and ensure that your HVAC works efficiently. However it is possible that if your ducts are well-sealed and you clean your filters frequently the cleaning of your ducts may not be necessary at all. You can only be certain by having your ducts examined. A contractor accredited by the EPA will use special testing methods in order to measure the amount particulates present in your ductwork. They can then recommend cleaning schedules that are appropriate for your particular situation.
Check the Compressor
The compressor is an important element of the system. It should be able supply cool air into the ducts. If the compressor isn’t functioning as it should and isn’t functioning properly, it could impact your productivity and lead to equipment downtime. Regular maintenance can help you identify small issues early, preventing unnecessary downtime. These regular checks will also save you money by making sure that your equipment as efficient as possible.
A reduction in cooling capacity is a common sign of a problem with a compressor. This can be caused by a variety of causes. A compressor may be working too hard due to poor airflow. This can cause wear on the bearings and reduce the lifespan of the compressor. Another issue that is common is a clogged filter. Filters that are blocked can restrict airflow and cause the compressor to overheat. It is essential to change or clean the filters in accordance with the manufacturer’s recommendations.
In addition, a clogged filter could 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 pulleys and belts on a regular basis. A belt or pulley that is loose can cause slippage and cause compressor overheating and other problems. It is recommended to drain the compressor on a regular basis. This will eliminate the moisture that could cause corrosion to the motor and other parts. A professional service team can also look for air leaks in the hoses and an adequate seal between the compressor and pressure switch.
Lastly, a puddle of water near the compressor can be an indication of a leak in the refrigerant. This could be a dangerous problem that must be dealt with immediately. If you suspect there is a leak, switch off the air compressor and call an expert.
Check the Thermostat
It’s not a surprise that technicians will always examine the thermostat first if there is any issue. A properly maintained thermostat is vital to the proper operation of your HVAC system. It’s one of the most frequently neglected maintenance items. Common indicators that your thermostat requires periodic inspections include incorrect temperature readings, non-responsive controls, or continuous cycling.
Inaccurate Temperature Readings
Thermostat sensors can become dirty over time, which can cause the device to display inaccurately. Regularly checking your thermostat’s accuracy with a separate thermometer will help you avoid these problems and help you save energy.
A malfunctioning sensor or calibration could result in your system constantly switching on and off this is known as short cycling. This can negatively impact your comfort and cause unnecessary wear and tear on the compressor. Fortunately, these issues can often be fixed with the simple act of replacing the thermostat’s batteries or resetting the breaker.
Check the breakers for your thermostat and HVAC equipment if your system doesn’t respond to your thermostat. If the breaker has tripped, it will require resetting to allow the thermostat to connect with the system once more.
Check your thermostat for signs of wear and tear. Look for signs of dirt or dust and ensure that the thermostat isn’t too exposed to sunlight. Examine the fan blades for signs of rust and damage. These simple checks will prevent costly repairs in the future, and ensure that your equipment operates as smoothly as it possibly can.
The simple maintenance of hvac systems on your commercial property is a great way to reduce energy consumption, ensure comfort, and extend the longevity of your heating and cooling equipment. By identifying any issues with your thermostat, setting the breaker and replacing the batteries in the process, you’ll be able keep your building comfortable all year. Make sure that should you encounter any other issues or aren’t sure the issue make sure to contact an expert.
