The Importance of HVAC Maintenance
When it comes to your cooling and heating system, routine maintenance is the key to avoiding costly repairs or early-than-necessary replacement. The majority of HVAC companies offer a service plan that charges each month to have the system checked and cleaned or repaired when required.
It is also recommended to perform DIY maintenance throughout the year. This includes cleaning or replacing air filters and keeping the space around outdoor units free of clutter to allow for proper airflow.
Clean the Condenser
The coils that make up the condenser of your air conditioner are the mainstay of the cooling process. If they’re dirty your system will be unable to cool properly and may even fail to function properly. Cleaning them is an essential component of HVAC maintenance. It is relatively easy to do. This simple DIY task will save you money, avoid costly repairs, and increase the lifespan of your air conditioner.
It is crucial to disconnect power from your unit first. This can be done 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 becoming oversaturated while cleaning.
When the power is turned off it is now time to clear any large debris that is obstructing the air condenser unit. This includes sweeping away any sticks, leaves, or other debris that have been accumulating on or around the unit. A shop vacuum equipped with a crevice attachment is a great way to get into the nooks and crevices and loosen any dirt, dust or other debris that has collected.
The next step is to clean the coils. Before you begin, though, make sure you have a few key tools. These include a concentrate for coil cleaning and a pump-up garden hose and a garden hose. Spray the coil cleaner on in accordance with the directions on the label of the product and then rinse it off using the hose. It is crucial not to apply too much pressure when washing the coils, as the fins can easily be bent.
You should inspect the coils for signs of damage following cleaning. Over time, the impact of hail and stones dropped by lawnmowers or other items can damage coil fins. If the fins are bent, a cost-effective tool known as a fin comb can straighten them to improve air flow and aid in the operation of the coils more effectively.
Once the coils and fins are in good condition, you can return to your home and turn on your air conditioning. Check the thermostat after about 24 hours to ensure the temperatures are in good shape.
Cleaning the Ductwork
Your HVAC system is able to bring outside air into your home, cool it, and then distribute it throughout your home. The air travels from the evaporator coil inside your condenser unit to the vents and registers of your home through a system of ducts. These ducts can become clogged with dust and other contaminants when they aren’t maintained and sealed properly. This could block air filters which reduces the effectiveness of your system as well as burdens your AC unit.
In the majority of cases, cleaning the ductwork isn’t an easy job and requires professional equipment and methods. There are some actions you can take regularly to ensure that your ducts are clean and working well. First, change your filter regularly to prevent dust and allergens out of building up in the ducts. This also helps to stop the clogging that could cause a decrease in system efficiency and a high energy bill.
Another way to help keep your ducts clean is by regularly cleaning the area around the vent openings. Using the hose attachment on your vacuum cleaner can remove all cobwebs and crumbs that accumulate over time and assist in improving airflow through the vent. It is also essential to make sure your ducts are sealed and sealed with insulation to keep out moisture, which can cause mold and other biological contaminants.
Ducts that are not regularly cleaned are likely to be contaminated with a myriad of contaminants, such as dust, pet dander, and pollen. These particles can cause respiratory and allergy conditions particularly for children and the elderly. Moisture in ductwork can also lead to the growth of mold, which releases spores into the air and poses health concerns for those suffering from respiratory issues.
It is generally recommended that you have your ducts cleaned every three to five years to remove the toxins and ensure that your HVAC system is operating effectively. However, if your ducts are sealed properly and you regularly change your filters the cleaning of your ducts may not be necessary at all. The best way to determine for certain is to have your ducts tested. A contractor that is certified by the EPA can use specific testing methods 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 critical component of the system. It needs to operate correctly to supply cool air to the ducts. If the compressor isn’t functioning in the way it should, this could affect your productivity and result in delays for your equipment. Fortunately, preventive maintenance is able to assist in identifying issues that are minor and help avoid prolonged downtime. These regular checks will also save you money by making sure that your equipment in the best condition possible.
A typical sign of a compressor problem is a reduction in cooling capacity, however it could be caused by various factors. One possibility is that a compressor could be under-performing due to inadequate airflow. This can cause wear on the bearings and diminish the lifespan of the compressor. Another common problem is a clogged filter. Filters that are blocked can restrict airflow and cause the compressor to overheat. It is essential to clean or replace the filters according to the manufacturer’s guidelines.
A blocked filter could also cause rattling noises in the compressor. This could indicate that the bearings require to be replaced. Regularly replacing belts and pulleys is recommended. A belt or pulley that is loose could cause slipping and result in compressor overheating and other problems. It is also a good idea to drain your compressor regularly. This will help remove moisture that can corrode the motor and other components. A professional service team will also look for leaks in the pipes, and ensure an adequate seal around the pressure sensor and compressor.
A puddle of liquid in the vicinity of the compressor could be a sign of a leak. This is a potentially dangerous problem that must be dealt with immediately. If you suspect that there is a leak, shut off the air compressor. Contact a professional.
Check the Thermostat
The thermostat acts like the boss of your HVAC system, so it’s no surprise that it’s the first thing a technician will check when trouble arises. It’s also among the most frequently neglected maintenance items, yet an appropriately maintained thermostat is vital to ensure your HVAC system’s operation. Common signs that your thermostat requires a check-up include incorrect temperature readings, unresponsive controls, or constant cycling.
Inaccurate Temperature Readings
Over time the sensors on your thermostat can become dirty. This can cause it to display in a wrong manner. You can prevent these issues by regularly checking the accuracy of your thermostat with an additional thermometer.
A malfunctioning sensor, or a faulty calibration can cause your system to turn off and on in a continuous manner. This is called short cycling. This can affect your comfort and result in unnecessary wear and tear to the compressor. Fortunately, these issues can often be fixed with simply replacing the thermostat’s batteries or resetting its breaker.
If your system isn’t responding to your thermostat in any way, it’s recommended to examine the breakers that regulate the thermostat and your HVAC equipment. If the breaker has tripped, it’ll require resetting in order for the thermostat to connect with the system again.
Examine your thermostat for signs of wear and damage. Look for signs of dirt or dust, and make sure the thermostat isn’t exposed to sunlight. Examine the fan blades to find evidence of damage or rust. These simple checks will help prevent costly repairs in the future, and help ensure that your equipment is operating as efficiently as it is possible.
Performing basic hvac maintenance on your commercial building is an excellent method to cut energy consumption, ensure comfort, and extend the lifespan of your cooling and heating equipment. You can ensure that your building stays comfortable throughout the year by identifying problems with your thermostat, resetting your breaker and changing your batteries. Make sure to contact an expert if you’re having other issues or aren’t sure what’s going on with your system.
