The Importance of HVAC Maintenance
When it comes to your heating and cooling system, regular maintenance is the best way to avoid costly repairs or early-than-necessary replacement. Most HVAC companies have a maintenance plan that charges a monthly fee to have your system checked and cleaned or repaired when required.
It’s also an excellent idea to carry out a few DIY maintenance tasks throughout the year. Cleaning or replacing air filters, and keeping the area surrounding the outdoor units free of debris will promote the proper flow of air.
Clean the Condenser
The coils inside the condenser of your air conditioner are the heart of the cooling process. If they are dirty, you system will struggle to cool and could even breakdown. This is why cleaning them is a vital part of HVAC maintenance. It is, fortunately, relatively simple to complete. This simple DIY task can prevent the need for expensive repairs, save you money on your energy bills and extend the life of your air conditioning unit.
It is vital to cut off power from your unit before you disconnect it. You can do this by shutting off the breaker in your electrical box, or the outdoor unit disconnect switch. This will prevent your motors and other electrical components from getting overloaded during cleaning.
After the power is off, you can start taking down any large debris that could be blocking the air condenser. This means sweeping off any sticks, leaves or other debris that has accumulated on or around the unit. Utilizing a shop vacuum that has crevice attachments is a great option to reach into the crevices and nooks and remove any dust, dirt or other debris that may have accumulated.
The next step is to clean the coils. Make sure you have some essential tools available before you begin. Included in this are a coil cleaning concentrate as well as a pump-up garden sprayer as well as a garden hose. Spray the coil cleaner in accordance with the directions on the label, then rinse with the water hose. It is crucial not to apply too much pressure when washing the coils since the fins could easily be bent.
It is recommended to inspect the coils for signs of damage following cleaning. Over time, the impact of hail and stones that are thrown by lawnmowers and other items can damage coil fins. If the fins are bent, a low-cost tool known as a fin-comb can straighten them to improve air flow and to aid in the operation of the coils more effectively.
Once you have a good coil and fin set up and you are ready to start your air conditioner. Check the thermostat every 24 hours to confirm that the temperatures are in good shape.
Cleaning the Ductwork
Your HVAC system works by bringing air in from outside, cooling it and then distributing it throughout your home. The air is moved from the evaporator coil of your condenser unit and then to your house’s vents and registers through a system of ducts. If these ducts aren’t properly cleaned and sealed, they can be laden with dust and other contaminants. This can clog the air filters, which decreases the efficiency of your system and burdens your AC unit.
In the majority of instances, cleaning ductwork isn’t an easy task that requires professional equipment and techniques. There are a few actions you can take regularly to ensure that your ducts are clean and in good working order. To prevent dust and allergens from accumulating in the ducts, it is recommended to change your filter on a regular basis. This can also help stop the clogging that could lead to reduced system efficiency and high energy bills.
Another way to keep your ducts clean is by regularly cleaning the area around vent openings. The hose attachment of your vacuum cleaner will take away all traces of dust, crumbs and other debris that has built up over time. This will improve airflow through the vent. You should also make sure that your ducts are sealed tight and lined to stop moisture from entering, which can lead to mold and other biological contaminants.
If ducts are not regularly cleaned, they may build up a myriad of contaminants like dust, pet dander, and pollen. These particles can exacerbate allergies and respiratory issues, particularly in the elderly and children. The moisture can cause mold to develop in ductwork, which releases microbes that can harm people suffering from respiratory issues.
It’s generally recommended that you have your ducts cleaned every three to five years in order to eliminate these contaminants and ensure your HVAC system is working efficiently. However If your ducts are sealed and you clean your filters frequently the cleaning of your ducts may not be required at all. You can be certain that your ducts are in good condition by having them checked. A contractor accredited by the EPA can use specific testing methods to measure the amount particulates found in your ductwork. They can then recommend cleaning schedules that are suitable for your particular situation.
Check the Compressor
The compressor is a critical element of the system. It should be able deliver cool air into the ducts. If the compressor isn’t functioning properly, it can affect your productivity and result in delays for your equipment. Preventive maintenance can help identify minor issues early, preventing unnecessary downtime. Performing these routine checks can also help you save money by ensuring that your equipment is in good shape for as long 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 causes. A compressor may be operating too hard due to poor airflow. This can cause wear on the bearings and decrease the life of the compressor. A blocked air filter is another common issue. If the filter has become clogged, it can reduce the airflow to the compressor and lead to overheating. It is crucial to clean or change the filters according to the manufacturer’s instructions.
A clogged filter may also cause rattling sounds in the compressor. This could be an indication that the bearings need to be changed. It is also a good idea to replace belts and pulleys on a regular basis. A belt or pulley that is loose can cause slippage and cause overheating of the compressor and other issues. It is recommended to drain the compressor on a regular basis. This will help remove moisture that can corrode the motor and other components. A professional service team can also check for air leaks in the hoses, and ensure a tight seal between the compressor and pressure switch.
A puddle of liquid in the vicinity of the compressor could be an indication of a leak. This is a potentially dangerous issue that needs to be addressed immediately. If you suspect there is a leak, switch off the compressor that is running and then contact an expert.
Check the Thermostat
The thermostat is like the head of your entire HVAC system, so it’s no surprise that it’s the first thing a technician will look at when trouble arises. It’s also among the most frequently neglected maintenance items, but maintaining your thermostat properly is vital to ensure your HVAC system’s operation. Common signs that your thermostat is in need of a check-up include incorrect temperature readings, non-responsive controls, or constant cycling.
Inaccurate Temperature Readings
Thermostat sensors can get dirty over time, which could cause the thermostat to display inaccurately. You can avoid this issue by regularly checking the accuracy of your thermostat by using a a separate thermometer.
A faulty sensor or calibration can also result in your system constantly switching off and on, which is referred to as short cycling. This can have a negative impact on your comfort as well as cause excessive wear and tear on the compressor. Fortunately this can be fixed with the simple act of replacing the thermostat’s batteries or resetting the breaker.
Check the breakers for your HVAC equipment and thermostat If your system isn’t responding to your thermostat. If the breaker has tripped, it will have to be reset in order for the thermostat to connect with the system once more.
Check your thermostat for signs of wear and damage. Check for dirt or dust and ensure that the thermostat isn’t too much exposed to sunlight. Check the fan blades for signs of rust and damage. This simple check will help avoid costly repairs in the future, and ensure that your equipment is running as smoothly as possible.
The simple maintenance of hvac systems on your commercial property is a great way to reduce energy costs, maintain comfort, and extend the lifespan of your cooling and heating equipment. By identifying any issues with your thermostat, setting the breaker and replacing the batteries and fuses, you’ll be able keep your building warm all year. Be sure to call a professional if you are experiencing any other issues or unsure of what is wrong with your system.
