The Importance of HVAC Maintenance
Maintenance is crucial when it comes to HVAC and cooling systems. It can help you avoid costly repairs or premature replacement. The majority of HVAC companies offer a service plan where you pay an affordable monthly fee to have your system checked, fixed or cleaned if necessary.
It’s also recommended to do a few DIY maintenance tasks throughout the year. These include cleaning or replacing air filters, and keeping the areas around outdoor units clear of clutter to allow for proper airflow.
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 may even break down. Cleaning them is an essential component of HVAC maintenance. It is relatively easy to complete. This simple DIY task will help you save money, avoid costly repairs, and increase the life of your air conditioner.
It is the first step. It is crucial to shut off the power supply to your unit. This can be done by shutting off the breaker inside your electrical box or at the outdoor unit disconnect switch. This will protect your electrical components and motors from being flooded during cleaning.
When the power is turned off and you are able to clean up any large debris obstructing the air condenser unit. This includes sweeping away any sticks, leaves or other debris that has built up 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 get rid of any dust, dirt or other debris that has collected.
The coils require to be cleaned. Before you begin however, make sure that you have on-hand some essential tools. This will include a coil cleaner concentrate and a pump-up garden sprayer and a garden hose. Spray the coil cleaner on according to the directions on the product label and then rinse using the hose. When washing the coils, it is important to not use too much force since the fins can bend easily.
After the coils have been cleaned, inspect them for any indications of damage. Over time, the impact of hail and stones dropped by lawnmowers or other objects can cause damage to coil fins. If the fins are bent, a low-cost 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.
Once the coils and fins are in good condition, you can go back to your home and start your air conditioning. After around 24 hours, you should check the thermostat and make sure that temperatures are normal.
Clean the Ductwork
Your HVAC system works to bring outside air into your home, cool it and then distribute it throughout the house. The air is moved from the evaporator coil of your condenser unit to your house’s vents and registers through a network of ducts. The ducts could become blocked with dust and other pollutants if they are not cleaned and sealed correctly. This can block the air filters, which in turn reduces the efficiency of your system and strains your AC unit.
In the majority of instances, cleaning ductwork is not an easy task and requires the help of professional equipment and techniques. However, there are a few things you can do on a regular basis to ensure that your ducts are in good condition and function properly. First, change your filter regularly to keep dust and allergens from building in the ducts. This can also help prevent the clogging that can lead to reduced system efficiency and high energy bills.
Another method to keep your ducts tidy is to regularly cleaning the area around the vent openings. Utilizing the hose attachment of your vacuum cleaner, you can eliminate all the cobwebs and crumbs that accumulate over time and assist in improving airflow through the vent. It’s also important to make sure your ducts are tightly sealed and insulated to keep out moisture which can cause mold and other biological contaminants.
If ducts aren’t regularly cleaned, they may accumulate a variety of contaminants like dust, pet dander, and pollen. These particles can cause a flare-up of respiratory issues and allergies, especially in 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 with respiratory problems.
It’s generally recommended that you get your ductwork cleaned every three to five years in order to eliminate these contaminants and ensure your HVAC system is operating efficiently. If your ducts are sealed properly, and you change your filter regularly, it may not be necessary to clean them. The best way to be able to tell for sure is by having your ducts tested. A contractor who is accredited by the EPA can use special testing techniques to determine the amount of particulates present in your ductwork. They can then recommend cleaning schedules that are suitable for your situation.
Check the Compressor
The compressor is a crucial component of the system. It needs to operate properly to deliver cool air to the ducts. If the compressor isn’t operating as it should, this can affect your productivity and result in interruption to your equipment. Regular maintenance can help you identify minor issues early, preventing excessive downtime. Regularly checking your unit can also help you save money by ensuring that your equipment is in good working order for as long as possible.
A loss of cooling capacity is a common sign of a problem with a compressor. This could be caused by a variety of causes. A compressor may be working too hard due to inadequate airflow. This could cause bearings to wear down and decrease the life of the compressor. Another common problem is a blocked filter. If the filter is clogged it could reduce the airflow to the compressor and cause overheating. It is important to clean or replace the filters according to the manufacturer’s recommendations.
A blocked filter can cause rattling sounds in the compressor. This could mean that the bearings are wearing out and require to be replaced. Regularly replacing belts and pulleys is an excellent idea. A loose pulley or belt can slip and lead to compressor overheating and other problems. It’s 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 hoses, as well as an adequate seal around the compressor and pressure sensor.
Finally, a small puddle of water around the compressor can be a sign of a refrigerant leak. This is a potentially dangerous problem that must be dealt with immediately. If you suspect a leak, shut off the air compressor. Consult a professional.
Check the Thermostat
It’s not too surprising that a technician will always look at the thermostat first when there’s any issue. It’s also one of the most often neglected maintenance items, yet maintaining your thermostat properly is crucial for ensuring your HVAC system’s optimal operation. Examine your thermostat if you find inaccurate temperature readings, ineffective controls, or continuous cycling.
Inaccurate Temperature Readings
Over time the thermostat’s sensors will become dirty. This can cause it to display inaccurately. You can avoid these problems by regularly checking the accuracy of your thermostat by using a the use of a separate thermometer.
A malfunctioning sensor, or a faulty calibration can cause your system to turn off and on constantly. This is known as short cycling. This could have a negative effect on your comfort as well as cause excessive wear and tear on the compressor. The problem can be fixed by replacing the batteries in the thermostat or resetting the breaker.
If your thermostat isn’t responding to your thermostat in any way It’s recommended to examine the breakers that control the thermostat as well as your HVAC equipment. If the breaker tripped it, you’ll need to reset it in order for your thermostat to reconnect with the system.
It is also essential to examine your thermostat for signs of wear or damage. Look for dust or dirt and ensure that the thermostat is not excessively exposed to the sun. Examine the fan blades to find signs of rust and damage. These simple checks can prevent costly repairs in the future, and will ensure that your equipment is operating as efficiently as possible.
Conducting basic HVAC maintenance on your commercial building is an excellent way to cut down on energy consumption, ensure comfort and extend the lifespan of your heating and cooling equipment. By identifying any issues with your thermostat, resetting the breaker, and then replacing the batteries and fuses, you’ll be able keep your building warm all year round. Make sure that should you encounter any other issues, or aren’t sure what’s wrong with your system you should always consult an expert.
