The Importance of HVAC Maintenance
Maintenance is essential when it comes to heating and cooling systems. It will allow you to avoid costly repairs or premature replacement. The majority of HVAC companies offer a service plan that charges the monthly cost to have the system checked, repaired or cleaned as required.
It’s also a good idea to perform a few DIY maintenance tasks throughout the year. Cleaning or replacing air filters, and keeping the area around outdoor units clear of clutter will help ensure the proper flow of air.
Clean the Condenser
The coils of the condenser of your air conditioner are at the heart the cooling process. If they’re dirty, your system will be unable to cool properly and could even fail. Cleaning them is a crucial part of HVAC maintenance. It’s fairly easy to do. This easy DIY task can prevent the need for costly repairs, save you money on your energy bills, and extend the longevity of your AC unit.
It is vital to cut off power from your unit first. This can be done by shutting off the breaker inside your electrical box or by turning off the outdoor unit disconnect switch. This will prevent your motors and electrical components from being flooded during cleaning.
When the power is turned off and you are able to clean up any large debris blocking the air condenser unit. This includes sweeping up any leaves, sticks, or other debris that have built up around or on the unit. Using a shop vacuum with a crevice attachment is a great way to reach into the nooks and crannies and remove any dirt, dust or other debris that has collected.
Next, it is time to clean the coils. Be sure to have some essential tools available prior to beginning. These include a concentrate of the coil cleaner and a pump-up garden hose and a garden hose. Spray the coil cleaner according to the instructions on the label, then rinse it off using a garden hose. When washing the coils, it is important to not use too much force as the fins can bend easily.
After the coils have been cleaned, examine them for indications of damage. 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 known as a fin comb can straighten them for better air flow and also to aid in the operation of the coils more effectively.
When the fins and coils are in good shape, you can go back to your home and turn on your air conditioning. After around 24 hours, you can examine the thermostat and make sure that temperatures are normal.
Cleaning the Ductwork
Your HVAC system is able to bring air from outside into your home, cool it, and then distribute it throughout your home. The air moves from the evaporator coil in the condenser unit to your house’s vents and registers through a network of ducts. If the ducts aren’t cleaned and sealed, they may become clogged with dust and other pollutants. This causes air filters to become blocked and reduces the efficiency of the system and strains your AC unit.
Cleaning the ductwork can be a challenging task that requires specialized equipment and methods. However, there are a few things you can do regularly to ensure that your ducts are clean and well-functioning. To avoid dust and allergens from accumulating in the ducts, change your filter on a regular basis. This can also help keep clogs from occurring, which could result in a decrease in system efficiency and higher energy bills.
Another way to help keep your ducts tidy is to regularly cleaning the area around the vent openings. Utilizing the hose attachment of your vacuum cleaner, you can get rid of all the cobwebs and crumbs that accumulate over time, and will aid in improving air flow through the vent. It is also important to make sure your ducts are sealed and sealed with insulation to keep out moisture which can cause mold and other biological contaminants.
If ducts aren’t cleaned regularly, they could build up a myriad of contaminants such as dust, pet dander and pollen. These particles can cause allergies and respiratory problems particularly for children and the elderly. In addition, moisture in ductwork may result in the growth of mold, which releases spores into the air and poses health risks for those with respiratory problems.
It is generally recommended that you have your ductwork cleaned every three to five years to remove the toxins and ensure that your HVAC system functions effectively. However, if your ducts are well-sealed and you change your filters regularly it is possible that duct cleaning won’t be necessary at all. You can be certain that your ducts are in good condition by having them checked. A contractor who is accredited by the EPA can employ special testing techniques to determine the amount of particulates that are present in your ductwork. They will then suggest cleaning schedules that are appropriate for your situation.
Check the Compressor
The compressor is an essential component of the system. It should be able deliver cool air into the ducts. If the compressor isn’t operating properly and isn’t functioning properly, it could impact your productivity and lead to the equipment to shut down. Preventive maintenance can help identify minor issues early, preventing unnecessary downtime. Performing these routine checks can also save you money by ensuring that your equipment is in good shape for as long as is possible.
A decrease in cooling capacity is a common sign of a problem in a compressor. It could be caused by a variety of causes. A compressor could be working too hard due to poor airflow. This could cause bearings to wear out and reduce the lifespan of the compressor. A clogged air filter is another common issue. If the filter is blocked it could reduce the airflow to the compressor and cause overheating. To prevent this, it is crucial to clean or change the filters on a regular basis, based on the manufacturer’s recommendations.
A blocked filter can cause rattling sounds in the compressor. This could be a sign that the bearings need to be replaced. It is also a good idea to replace belts and pulleys regularly. A belt or pulley that is loose can slip and lead to compressor overheating and other issues. It is also a good idea 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 ensure an adequate seal between the compressor and the pressure switch.
A puddle of liquid close to the compressor could be an indication of a leak. This is a serious issue that needs to be addressed right away. If you suspect that there is a leak, shut off the air compressor. Get a professional to assist you.
Check the Thermostat
The thermostat acts like the boss of your HVAC system, and it’s no surprise that it’s the first thing that a technician will check when trouble occurs. A properly maintained thermostat is vital to the proper operation of your HVAC system. It’s one of the most neglected maintenance items. Examine your thermostat if you find inaccurate temperature readings, unresponsive controls, or constant cycling.
Inaccurate Temperature Readings
Thermostat sensors can become dirty over time, which may cause the thermostat to display incorrectly. Monitoring your thermostat’s accuracy regularly by using a separate thermometer can assist you in avoiding these issues and conserve energy.
A faulty sensor or calibration can also result in your system constantly switching on and off, which is referred to as short cycling. This can have a negative impact on your comfort as well as cause unnecessary wear and tears on the compressor. Fortunately this can be fixed with the simple act of replacing the batteries in your 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 regulate the thermostat as well as your HVAC equipment. If the breaker tripped it, you’ll need to reset it to allow your thermostat to reconnect with the system.
It is also essential to examine your thermostat for signs of wear or damage. Check for evidence of dust or dirt, and make sure the thermostat isn’t exposed to sunlight. Check the fan blades for evidence of damage or rust. These simple checks will prevent costly repairs in the future and ensure that your equipment is running as smoothly as it can.
Performing basic hvac maintenance on your commercial building is an excellent way to cut down on the cost of energy, maintain comfort and prolong the lifespan of your heating and cooling equipment. You can keep your building cool throughout the year by identifying issues with your thermostat, setting your breaker, and then replacing your batteries. Be sure to call a professional if you have any other issues, or aren’t sure what’s wrong with your system make sure to contact an expert.
