Myths Surrounding AC Maintenance

In Dubai, air conditioning is essential due to the city’s extreme temperatures and high humidity, especially during the summer months when temperatures can soar above 40°C. For this reason, having reliable AC isn’t just a luxury—it’s a necessity for maintaining a quality standard of living. That being said, there are several myths surrounding the maintenance of air conditioners, and in this article, we debunk them.

Fact: When your air conditioner breaks down, calling for AC maintenance can lead to considerably more costly repairs. Regular preventative maintenance reduces the likelihood of unplanned problems, keeps your system functioning smoothly, and extends the life of your equipment. Similar to how a car needs regular tune-ups to avoid more serious issues, AC systems need routine maintenance to stay dependable and efficient. Skipping routine maintenance could save money in the short term, but there could be major functional and financial consequences in the long run.

Fact: The effectiveness of your air conditioning system depends on air filters, which prevent dust and debris from blocking the unit. The motor is strained, and energy expenses may rise as a result of the system's inability to draw air through dirty filters. Filters should ideally be changed every one to three months, depending on air quality and usage. More frequent filter changes may be necessary in homes with pets, smokers, or heavy traffic. In addition to lessening system stress, routine filter replacement enhances indoor air quality.

Fact: Even while it might make sense to switch off the air conditioner when you leave the house, turning it on and off repeatedly makes the system work harder to chill the room again. Setting a programmable thermostat to change the temperature while you're away is a more energy-efficient method. Maintaining efficiency without placing undue strain on the system can be achieved by keeping the temperature a little higher when no one is home and bringing it down to your chosen setting just before you return.

Fact: It’s a common misconception that a new AC unit doesn’t need maintenance. While new units typically perform efficiently, regular maintenance helps retain that efficiency and ensures the system continues to run optimally. Moreover, many manufacturers require proof of regular maintenance to honor the warranty. Ignoring upkeep on a new unit can not only void the warranty but also accelerate wear and tear, leading to avoidable repairs and replacement costs down the line.

Fact: An AC unit should be sized according to the area it needs to cool. Oversized units can cause the system to cycle on and off more frequently, wasting energy and failing to adequately dehumidify the space. On the other hand, undersized units will constantly run without adequately cooling the area. Both scenarios lead to inefficiency and higher energy costs. Consulting an HVAC professional to determine the correct size for your space will help avoid these issues and result in optimal cooling and energy usage.

Fact: Unlike gasoline in a car, refrigerant in an AC system doesn’t “get used up.” Your system should have a constant amount of refrigerant, and the only reason it would need refilling is if there’s a leak. Routine maintenance checks can help detect leaks early, preventing them from causing larger issues down the line. Adding refrigerant without fixing a leak is only a temporary fix and can lead to a continuous cycle of refills and higher repair costs.

Fact: Some parts of maintenance are best left to experts, even if homeowners may perform simple chores like cleaning the unit and changing the air filters. Professional HVAC technicians are educated to check for any hidden problems that may not be apparent to the untrained eye, clean and lubricate equipment, check refrigerant levels, and make sure electrical components are in good condition. These thorough checkups can assist in identifying minor issues before they become more serious and require costly repairs.

Fact: An AC system that is properly maintained operates more effectively, which reduces energy expenses. Dirt and debris buildup can impede airflow and lower performance; routine cleaning and tune-ups help avoid this. Maintaining air conditioners can really reduce energy expenses by as much as 15%, according to studies. However, neglecting maintenance increases the likelihood of system failures and electricity costs, which can be expensive during the height of the cooling season.

Fact: Different types of AC systems, such as central air, window units, and split systems, have unique maintenance requirements. For example, central air systems benefit from duct cleaning every few years, while window units require regular coil cleaning. Understanding the specific maintenance needs of your AC type can ensure optimal performance and avoid unnecessary costs.
