The heat in the Evanston and Greater Chicagoland areas takes a toll on your air conditioner, especially if it hasn’t been properly maintained. Common problems are sometimes an easy DIY fix, but more often, they require the expertise of a technician, and even simple problems can be expensive to repair. Here are five common A/C problems and what you can do to address them.
When airflow is restricted, the system can overheat and cause expensive damage. If the A/C isn’t blowing out much air, or if your evaporator coil freezes, look for obstructions or leaks in the ductwork and in the return and supply registers. Check your filter and replace it if it’s clogged with dust, which prevents optimum airflow.
Clogged Condensate Drain
When the humidity rises, evaporation drips from the indoor coil into the condensate pan below. Clogs cause the water to back up and shut down your air conditioner. Remove the clog, which may be in the pan or in the plastic drain tube.
If your system is low on refrigerant, it could have a leak. If the air coming out of the supply registers isn’t cool, or if your evaporator coil ices over, a professional will need to measure the refrigerant level, detect and repair leaks, and top off the system with refrigerant to improve comfort and cut cooling costs.
When the evaporator and condenser coils are dirty, they can’t absorb and release heat optimally. This reduces the system’s cooling power and increases your energy bills. You can clean the coils yourself or call in a professional to do it for you. Meanwhile, change your air filter when it’s dirty and hose down your outdoor unit monthly.
Electric Control Problems
Loosened electrical connections, corrosion on wires and terminals, and worn-out controls can cause electric control failure, which requires expensive repairs and even system replacement. The only way to prevent this problem is through regular yearly maintenance.
