Yes, is the simple answer to whether or not an AC requires service every year. Of course, there is a more detailed answer to why an AC unit needs yearly servicing. A heating, ventilation, air conditioning unit is also called a HVAC system. It is an intricate unit that needs servicing at least once a year to keep it performing smoothly.
Another reason regular maintenance is important is the unit’s warranty. Parts and components of an AC are typically covered with a guarantee. However, the warranty can be voided and/or denied because the homeowner didn’t preserve the unit correctly. Thus, it’s important to have a professional check the unit so a homeowner can continue to use their warranty if any major problem develops with the AC unit.
What is a Yearly AC Service Repair?
Including the word “repair” is a little misleading. An AC technician doesn’t repair the HVAC unit. Instead, the conduct preventive maintenance. The preventive maintenance is done twice a year to detect and stop any problems that could occur with the AC in the future.
Regular maintenance is a complex process involving things like inspecting the unit for any potential issues and changing filters. The unit will also be cleaned so the unit won’t become clogged with debris, dirt and other materials.
The latter is vital to keeping an AC running smoothly. For example, air runs through the unit. If any component becomes blocked or obstructed, the unit may stop working, freeze up or experience a leak.
The condenser also needs regular maintenance. Evaporator coils and motors must be cleaned and free of all pollutants. Drain lines should be regularly checked and cleared. Water leaks can occur during the warmer months because the AC is working on overdrive. Water leaks can occur because of a blocked drain line caused by contaminants and dirt. If these things are taken care of before they become a problem, the AC will work properly.
The Types of Things a Professional Looks for to Keep an AC Running Smoothly
Regular maintenance must be performed at least twice a year. In fact, the spring and fall are times a homeowner should get the unit checked by a professional service technician. For example, a technician checks for the right amount of refrigerant and any leaks using a leak detector. They also check for any duct leaks in the ducts connected to the AC unit.
As mentioned before, an evaporator coil must be free of debris. Thus, the technician checks for airflow going through the evaporator coil. The thermostat is another important for factor in keeping an AC unit working efficiently. Belts are check for tightness so that they don’t come off while the AC unit is running.
What Homeowners can do to Assist a Technician in Keeping the AC Running Smoothly
There are some things a homeowner can do assist in keeping an AC running smoothly all year around. For instance, replace the existing filter every 90 days. This will keep the debris and dirt that builds up in the filter from reaching other parts of the HVAC. If the homeowner has pets, the filter should be changed every 30 days.
If the homeowner has an outdoor AC unit and heat pumps, it’s important to keep all debris, pollen, leaves and twigs away from the unit. This means sweeping around the unit.
Shut off the water supply to the humidifier in the furnace during the warmer months. During the fall or when cooler months, it’s important to replace the humidifier wick filter and set the humidistat to about 30 percent relative humidity. Also, turn the on the water supply.
Every year replace the carbon monoxide detector battery. This will assist with catching any carbon monoxide in the house before it harms the homeowner and/or family member. Another thing to do is make sure the outdoor AC unit is on level ground, so the unit can work properly.
Protecting an AC Unit from the Unexpected Breakdown
Every homeowner has experienced the worst nightmare in the summer. It’s hot. No, it’s super hot. They turn on the AC, and nothing happens. The AC doesn’t cool the air. Maybe it blows, but it doesn’t cool the room. There is an issue with the AC, and someone must repair it. Often, preventative service on an AC unit can prevent this from happening because they inspect the unit at least once a year. Remember, a unit should be serviced twice a year.
