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 service plan where you pay an annual fee to have the system checked and cleaned or repaired when required.
It’s also an excellent idea to carry out some of the DIY maintenance tasks throughout the year. These include cleaning or replacing air filters, and keeping the areas around outdoor units clear of debris to promote the proper airflow.
Clean the Condenser
The coils in the condenser of your air conditioner are the core of the cooling process. If they are dirty your system will struggle to cool properly and may even fail to function properly. This is why cleaning them is a vital part of HVAC maintenance. Fortunately, it is also relatively simple to complete. This easy DIY task will save you money, prevent expensive repairs and extend the life of your air cooling.
It is crucial to disconnect 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.
Once the power is off, you can begin taking down any large debris that may be hindering the air condenser. This means sweeping up any leaves, sticks or other debris that have built up around or on the unit. A shop vacuum equipped with a crevice attachment is a great option to get into the nooks and crannies and loosen any dirt, dust or other debris that has accumulated.
The next step is to clean the coils. Be sure to have a few essential tools in your arsenal before you start. Included in this are a coil cleaning concentrate and a pump-up garden sprayer and a garden hose. Spray the coil cleaner according 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 since the fins could easily be bent.
You should examine the coils for signs of damage after cleaning. Over time hail or stones thrown by lawnmowers, and other objects can cause damage to the coil’s fins. If the fins are bent, a cost-effective tool known as a fin comb can straighten them for better air flow and to assist in ensuring that the coils operate more effectively.
Once you have a good coil and fin set up and you are ready to start your air conditioner. After around 24 hours, you can check the thermostat and make sure that the temperature is normal.
Clean the Ductwork
Your HVAC system is able to bring air from outside, cooling it, and distributing it throughout your home. Air is transported from the evaporator in your condenser to your home’s registers and vents through the system duct. If these ducts aren’t properly cleaned and sealed, they may become loaded with dirt and other contaminates. This could block air filters which can reduce the effectiveness of your system and burdens your AC unit.
In the majority of instances, cleaning ductwork is not an easy job and requires professional equipment and methods. There are a few things you can do regularly to ensure that your ducts are clean and in good working order. To avoid dust and allergens from building up in the ducts, it is recommended to change your filter frequently. This will also help to stop clogging, which could lead to a reduced system efficiency and higher energy bills.
Cleaning the area around the vent openings is another way to keep your ducts cleaner. The hose attachment of your vacuum cleaner will get rid of all the crumbs, cobwebs and other debris that have been accumulating over time. This will improve airflow through the vent. Also, make sure that your ducts are sealed tightly and are insulated to prevent moisture from entering, which can cause mold and other biological contaminants.
If ducts are not cleaned regularly, they could build up a myriad of contaminants such as dust, pet dander, and pollen. These particles can worsen allergies and respiratory issues especially in the elderly and children. In addition, moisture in ductwork may result in the growth of mold which releases spores into air and can cause health issues for those with respiratory problems.
It is recommended to clean your ductwork every three to five year to get rid of these toxins and ensure that your HVAC works efficiently. However, if your ducts are sealed properly and you regularly change your filters the cleaning of your ducts may not be required at all. You can only be certain by having your ducts checked. A contractor that is certified by the EPA can use special testing techniques to measure the amount particulates that are present in your ductwork. They will then suggest cleaning schedules that are suitable for your particular situation.
Check the Compressor
The compressor is a crucial component of the system. It should be able deliver cool air into the ducts. If the compressor isn’t operating in the way it should and isn’t functioning properly, it could impact your productivity and result in equipment downtime. However, preventive maintenance can assist in identifying issues that are minor and help avoid prolonged downtime. Performing these routine checks can also save you money by keeping your unit in good working order for as long as it is possible.
A reduction in cooling capacity is a typical sign of a problem in the compressor. This could be caused by several different causes. A compressor could be working too hard due to poor airflow. This can cause the bearings to wear down and decrease the life of the compressor. Another common problem is a clogged filter. If the filter is blocked it can impede airflow to the compressor and lead to overheating. To avoid this, it is essential to clean or change the filters on a regular basis, based on the recommendations of the manufacturer.
A clogged filter may also cause rattling sounds in the compressor. This could be an indication that the bearings must be replaced. It is recommended 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 also a good idea to drain the compressor regularly. This will remove the accumulated moisture that could cause corrosion to the motor and other components. A professional service team will also check for air leaks in the hoses as well as a tight seal between the compressor and the pressure switch.
A puddle of liquid near the compressor could be a sign of an issue. This is a risky problem that must be dealt with immediately. If you suspect that there is a leak, switch off the air compressor and contact an expert.
Check the Thermostat
The thermostat is kind of like the head of your HVAC system, and it’s no surprise that it’s the first thing a technician will inspect when a problem arises. A well-maintained thermostat is crucial to the efficient operation of your HVAC system. It’s one of the most frequently neglected maintenance items. The most common signs that your thermostat needs a check-up include incorrect temperature readings, non-responsive controls, or constant cycling.
Inaccurate Temperature Readings
Over time, the thermostat’s sensors may become dirty. This could cause it to display in a wrong manner. Regularly checking your thermostat’s accuracy with a separate thermometer will aid in avoiding these issues and help you save energy.
A malfunctioning sensor, or a wrong calibration, could cause your system to cycle on and off in a continuous manner. This is known as short cycling. This can have a negative impact on your comfort and result in excessive wear and tear on the compressor. These issues can be resolved by replacing the thermostat’s batteries or resetting the breaker.
If your thermostat isn’t responding to your thermostat at all, it’s recommended to examine the breakers that control both the thermostat as well as your HVAC equipment. If the breaker has tripped then you’ll have to reset it to allow your thermostat to reconnect with the system.
It’s also crucial to examine your thermostat for any signs of wear or damage. Look for dust or dirt and make sure that the thermostat is not overly exposed to the sun. The fan blades must be inspected for signs of rust or damage. These simple checks will help prevent expensive repairs in the future, and ensure your equipment is running as smoothly as it can.
The simple maintenance of hvac systems on your commercial property is an excellent method to cut energy costs, maintain comfort, and extend the lifespan of your heating and cooling equipment. By identifying problems with your thermostat, resetting the breaker and replacing the batteries in the process, you’ll be able keep your building comfortable all year round. Make sure to contact an expert if you’re having any other problems or are unsure of what’s the issue with your system.
