The Importance of HVAC Maintenance
When it is about your cooling and heating system, maintenance is the best way to avoid costly repairs or replacements that are not needed as soon as they should be. Most HVAC companies offer a maintenance plan where you pay an affordable monthly fee to have your system checked out, fixed or cleaned when necessary.
It’s also a good idea to perform some DIY maintenance tasks throughout the year. This includes cleaning or replacing air filters, and keeping the areas around outdoor units clear of any debris to ensure the proper airflow.
Clean the Condenser
The coils in the condenser of your air conditioner are the mainstay of the cooling process. If they are dirty, you system will struggle to cool and could even fail. Cleaning them is an essential aspect of HVAC maintenance. It’s also relatively simple to complete. This easy DIY task can prevent the need for costly repairs, save you money on your energy bills, and prolong the lifespan of your air conditioning unit.
It is vital to cut off power from your unit before you disconnect it. This can be done by shutting off the breaker at your electrical box, or by turning off the outdoor unit disconnect switch. This will safeguard your motors and electrical components from being oversaturated when cleaning.
When the power is turned off, you can begin to remove any large debris that is obstructing the air condenser unit. This includes sweeping up any leaves, sticks or other debris that has accumulated around or on the unit. Using a shop vacuum with crevice attachments is a great option 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 doing this, though, make sure that you have in your possession some essential tools. These will include a concentrate of the coil cleaner, a pump-up garden sprayer and a garden hose. Spray the coil cleaner on according to the directions on the product’s label and rinse with the hose. When washing the coils, it is important not to apply too much force since the fins can be bent easily.
It is recommended to inspect the coils for signs of damage following cleaning. Over time, hail and rocks dropped by lawnmowers or other items could damage the coil fins. If the fins are bent, a cost-effective tool called a fin comb can straighten them to improve air flow and also to help the coils function more efficiently.
Once the coils and fins are in good condition If you are satisfied with the condition of your fins and coils, return to your home and switch on your air conditioner. After approximately 24 hours, you can check the thermostat and make sure that temperatures are normal.
Clean the Ductwork
Your HVAC system works to bring air from outside into your home, cool it, and then distribute it throughout your house. The air is moved from the evaporator coil of your condenser unit to the vents and registers of your home through a network of ducts. If the ducts aren’t cleaned and sealed, they may become loaded with dust and other pollutants. This can block the air filters which reduces the effectiveness of your system and can strain your AC unit.
Cleaning the ductwork can be a challenging task that requires specialized equipment and techniques. There are a few things you can do to keep your ducts tidy and working well. First, change your filter on a regular basis to prevent dust and allergens from building into the ducts. This also helps to prevent the clogging that can lead to reduced system efficiency and higher energy costs.
Another method to keep your ducts tidy is to regularly vacuuming the area around the vent openings. The hose attachment on your vacuum cleaner will get rid of all traces of dust, crumbs and other debris that have been accumulating over time. This will increase airflow through the vent. It’s also important to ensure that your ducts are sealed and insulated to keep out moisture which can lead to mold and other biological contaminants.
Ducts that are not regularly cleaned are likely to be contaminated with a variety of pollutants, including dust, pet dander and pollen. These particles can cause allergies and respiratory problems especially in children and the elderly. In addition, moisture in ductwork may result in the growth of mold, which releases spores into air and poses health risks for those with respiratory issues.
It is generally recommended that you have your ducts cleaned every three to five years to eliminate these contaminates and ensure that your HVAC system is operating efficiently. If your ducts have been sealed properly, and you replace your filter on a regular basis, it may not be necessary to clean them. The best way to determine for certain is to have your ducts tested. A contractor who is accredited by the EPA can use special testing methods in order to determine the amount of particles found in your ductwork. They will then recommend cleaning schedules that are appropriate for your particular situation.
Check the Compressor
The compressor is a crucial component of the system. It must be able to provide cool air to the ducts. If the compressor isn’t working properly, it could affect your productivity and result in downtime for equipment. However, preventive maintenance can help catch minor issues early and avoid excessive downtime. These routine checks will also save you money by making sure that your equipment in the best condition possible.
A common sign of a compressor issue is a reduction in cooling capacity, although it could be caused by various factors. A compressor may be operating too hard due to inadequate airflow. This could cause the bearings to wear down and reduce the lifespan of the compressor. A clogged air filter is another common problem. If the filter has become clogged it could reduce the airflow to the compressor and lead to overheating. It is important to clean or replace the filters according to the manufacturer’s instructions.
Additionally, a blocked filter may also cause rattling noises 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 worn belt or pulley could cause slipping and result in compressor overheating and other problems. It is also a good idea to drain your compressor frequently. This will eliminate the moisture that could cause corrosion to the motor and other parts. A professional service team will look for leaks in the pipes, and ensure an adequate seal around the compressor and pressure sensor.
A puddle of liquid near the compressor could be a sign of leak. This is a serious problem and needs to be fixed right away. If you suspect that there is a leak, turn off the air compressor. Consult a professional.
Check the Thermostat
The thermostat is like the boss of your entire HVAC system, and it’s not a surprise that it’s the first thing a technician will inspect when a problem occurs. A properly maintained thermostat is vital to the smooth operation of your HVAC system. It’s one of the most frequently neglected maintenance items. Common indicators that your thermostat requires an inspection include inaccurate temperature readings, non-responsive controls, or constant cycling.
Inaccurate Temperature Readings
Thermostat sensors can become dirty over time, which could cause the thermostat to display incorrectly. Monitoring your thermostat’s accuracy regularly with a separate thermometer will aid in avoiding these issues and help you save energy.
A malfunctioning sensor or calibration may result in your system constantly turning on and off this is known as short cycling. This can negatively impact your comfort and cause excessive wear and tear on the compressor. Fortunately, these issues can often be corrected by simply replacing the thermostat’s batteries or resetting its breakers.
If your thermostat isn’t responding to your thermostat at all It’s an excellent idea to look at the breakers that control both the thermostat and your HVAC equipment. If the breaker has tripped, it will require resetting to allow the thermostat to connect with the system again.
Examine your thermostat for signs of wear and damage. Look for dust or dirt and make sure that the thermostat is not too much exposed to sunlight. The fan blades should be checked for any signs of damage or rust. These simple checks can help avoid expensive repairs in the future, and ensure your equipment is operating as smoothly as possible.
Conducting basic HVAC maintenance on your commercial property is a great way to reduce the cost of energy, maintain comfort and prolong the lifespan of your heating and cooling equipment. You can ensure that your building stays comfortable throughout the year by identifying any issues with your thermostat, setting your breaker and changing your batteries. Be sure to call a professional in case you experience any other issues or are unsure about the issue you should always consult an expert.
