Top 5 Common AC Problems and How to Prevent Them

As summer heat intensifies, your air conditioner becomes your best friend. But like any machine, AC units can develop issues, especially if AC maintenance services in San Antonio, TX are not properly considered. Knowing the most common air conditioning problems - and how to prevent them - can save you time, money, and frustration. Here are the top 5 issues homeowners face with AC systems and some practical tips to keep them running smoothly.

1.   Refrigerant Leaks

➢      The Problem - Low refrigerant levels can lead to poor cooling performance, longer run times, and in some cases, complete system failure. Leaks can also damage the environment if not handled properly.

➢      Prevention - Schedule annual AC inspections by a certified technician to check refrigerant levels and detect leaks early. If your unit is older, consider an upgrade to a newer, eco-friendly system that uses safer refrigerants.

2.   Dirty or Clogged Filters

➢      The Problem - Air filters trap dust, pollen, and other particles. When they’re clogged, your AC struggles to circulate air efficiently, reducing airflow and straining the system.

➢      Prevention - Replace or clean your filters every 1 - 3 months depending on usage, pets, and allergy sensitivities. A clean filter not only improves efficiency but also enhances indoor air quality.

3.   Thermostat Malfunctions

➢      The Problem - An inaccurate or malfunctioning thermostat can lead to erratic temperatures and overuse of the system. This issue is common with outdated or incorrectly calibrated thermostats.

➢      Prevention - Upgrade to a programmable or smart thermostat. Not only do these offer better accuracy, but they also help optimize energy use. Also, check batteries regularly and ensure the thermostat is installed away from heat sources like windows or lamps.

4.   Frozen Evaporator Coils

➢      The Problem - Frozen coils block airflow and reduce cooling efficiency. This usually happens due to restricted airflow, low refrigerant levels, or dirty coils.

➢      Prevention - Keep filters clean and ensure return air ducts are not blocked. Hire a professional for air conditioning repair in San Antonio, TX to check refrigerant levels and clean the evaporator coil during routine maintenance to prevent ice buildup.

5.   Drainage Problems

➢      The Problem - Air conditioners remove humidity from the air, which exits through a drain line. If this line gets clogged with algae or debris, it can cause water leaks, mold growth, and even water damage to your home.

➢      Prevention - Flush the condensate drain line with a mixture of water and vinegar every few months. During servicing, ask your technician to inspect and clear the line to ensure proper drainage.

Final Thoughts

Your AC unit is a long-term investment that requires consistent care. While some issues are inevitable with age, most common AC problems can be avoided with preventive maintenance and timely checkups. A small amount of attention throughout the year can go a long way in ensuring your system keeps you cool efficiently and reliably. Consider getting seasonal San Antonio AC tune-ups by the experts at Shafer Services Plus - it is a simple habit that pays off with comfort and savings.
