The Importance of HVAC Maintenance
When it comes to your heating and cooling system, routine maintenance is the key to avoiding costly repairs or replacements that are not needed as soon as they should be. The majority of HVAC companies offer a service plan that allows you to pay an annual fee to have the system inspected, repaired or cleaned as required.
You should also carry out some DIY maintenance throughout the year. Cleaning or replacing air filters, and keeping the area around outdoor units free of debris will promote 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, you system will struggle to cool and could even breakdown. Cleaning them is an important aspect of HVAC maintenance. It’s also quite simple to do. This simple DIY task will help you save money, avoid costly repairs and prolong the life span of your air conditioner.
It is essential to disconnect the power source from your unit first. This can be done by shutting off the breaker in the electrical box, or by turning off the outdoor unit disconnect switch. This will stop your motors and other electrical components from getting overloaded when cleaning.
Once the power has been shut off, you can start removing any large objects that could be hindering the condenser’s air. This includes sweeping away any sticks, leaves or other debris that have accumulated on or around the unit. Using a shop vacuum with a crevice attachment is a great option to reach into the crevices and nooks and get rid of any dirt, dust or other debris that may have accumulated.
The coils must be cleaned. Make sure you have the necessary tools available before you begin. Included in this are a coil cleaning concentrate and a pump-up garden sprayer, and the garden hose. Spray the coil cleaner according to the directions on the label, then rinse it off using a water hose. It is important not to use excessive pressure when washing the coils, because the fins may be bent.
You should inspect the coils for signs of damage after cleaning. Over time, the impact of hail and stones that are thrown by lawnmowers and other items could damage the coil fins. Fin combs can be used to straighten bent fins for better airflow and performance of the coil.
After you have a proper coil and fin setup, you can turn on your air conditioner. After about 24 hours, you should check the thermostat to ensure that the temperature is normal.
Cleaning the Ductwork
Your HVAC system works by bringing air from outside, cooling it and then distributing it throughout your home. Air is moved from the evaporator inside your condenser unit to your home’s registers and vents through a system of ducts. If these ducts aren’t cleaned and sealed, they may be laden with dust and other contaminants. This could block air filters, which decreases the efficiency of your system and can strain your AC unit.
In the majority of cases, cleaning the ductwork is not an easy task 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, make sure you change your filter on a regular basis to keep dust and allergens out of building in the ducts. This will also help to stop clogging, which could lead to a reduced system efficiency and a higher cost for energy.
Cleaning the area around the vent openings is an additional method to keep your ducts cleaner. The hose attachment of your vacuum cleaner will take away all traces of dust, crumbs and other messes that have built up over time. This will increase the flow of air through the vent. It’s also important to ensure that your ducts are sealed and insulated to keep out moisture, which can lead to mold and other biological contaminants.
Ducts that aren’t cleaned on a regular basis are likely to be contaminated with a variety of contaminants, such as dust, pet dander and pollen. These particles can cause allergies and respiratory issues particularly in the elderly and children. The moisture can cause mold to grow in ductwork, which releases microbes that can harm those with respiratory problems.
It is generally recommended to have your ducts cleaned every three to five years to remove the toxins and ensure that your HVAC system functions effectively. However If your ducts are sealed properly and you change your filters regularly it is possible that duct cleaning won’t be necessary at all. The best way to determine for sure is by having your ducts tested. A contractor that is certified by the EPA will 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 an essential element of the system. It must function correctly to supply cool air to the ducts. If the compressor isn’t functioning properly, it can affect your productivity and result in downtime for equipment. Fortunately, preventive maintenance is able to assist in identifying issues that are minor and avoid excessive downtime. These routine checks will also save you money by ensuring that your equipment in the best condition possible.
A typical sign of a compressor issue is a decrease in cooling capacity, although this could be due to a number of different factors. One possibility is that a compressor may be overworking because of poor airflow. This can cause the bearings to wear out and decrease the life of the compressor. A clogged air filter is another frequent issue. Filters that are blocked can hinder airflow and cause the compressor to overheat. It is essential to clean or replace the filters in accordance with the manufacturer’s instructions.
A blocked filter could cause rattling sounds in the compressor. This could mean that the bearings are worn out and must be replaced. It is recommended to replace belts and pulleys on a regular basis. A worn belt or pulley could cause slipping and result in compressor overheating and other problems. It is also a great idea to drain your compressor regularly. This will get rid of the moisture that could cause corrosion to the motor and other parts. A professional service team will also check for leaks in the hoses, and an adequate seal around the pressure sensor and compressor.
Finally, a puddle of water near the compressor can be an indication of a leak in the refrigerant. This could be a risky issue and should be repaired right away. If you suspect there is a leak, shut off the air compressor and contact an expert.
Check the Thermostat
The thermostat is kind of 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 arises. It’s also one of the most often neglected maintenance items, but maintaining your thermostat properly is essential to ensure your HVAC system’s optimal operation. Common indicators that your thermostat is in need of periodic inspections include incorrect temperature readings, non-responsive controls, or constant cycling.
Inaccurate Temperature Readings
Over time the sensors on your thermostat can become dirty. This could cause it to display inaccurately. You can prevent these issues by ensuring the accuracy of your thermostat by using a an additional thermometer.
A faulty sensor or calibration can also lead to your system continuously switching off and on, which is referred to as short cycling. This could have a negative effect on your comfort and cause excessive wear and tear on the compressor. Fortunately this can be fixed with simply replacing the thermostat’s batteries or resetting its breakers.
Check the breakers for both your HVAC equipment and thermostat if your system doesn’t respond to your thermostat. If the breaker tripped it, you’ll need to reset it to allow your thermostat to communicate again with the system.
Check your thermostat for signs of wear and tear. Check for indications of dust or dirt and ensure that the thermostat isn’t too exposed to sunlight. Finally, the fan blades should be checked for signs of damage or rust. These simple checks can prevent expensive repairs in the future, and ensure your equipment is running as smoothly as it is possible.
Basic hvac maintenance is a great way to reduce energy costs and maintain comfort in your commercial property. It can also prolong the life of cooling and heating equipment. By identifying issues with your thermostat, setting the breaker, and replacing the batteries and fuses, you’ll be able keep your building comfortable all year. Remember to call an expert if you’re having other issues or are unsure of what’s going on with your system.
