Troubleshooting Your AC This Summer


Air Conditioner

We’re right in the middle of it…. blistering summer days, blazing sun, and high humidity. While we gravitate toward more outdoor time with the advent of warmer weather, we still like to retreat from time to time into the cool refreshment of a home that is properly cooled and comfortable.


Those of us who live in southern states know the agony of an air conditioning unit that isn’t working well. Nothing is quite as uncomfortable as not being able to cool off after a hot day of work, or worse yet, to toss and turn in a pool of sweat at night when you’re unable to find comfortable sleep.


It is essential to have an HVAC unit that works well in warmer climates; while you wait for a qualified technician to service or replace your unit, why not do some troubleshooting and develop an initial diagnosis to see if something can be done in the meantime? Read on to see how you can pinpoint an issue and potentially save both time and money in the process:


Why isn’t my AC working?

An air conditioning unit has to work overtime in the hot summer months to remove humidity and cool air inside your home. It’s understandable then, that these units get overworked from time. Here are some common issues that happen with HVAC units during periods of overload, and things you can do to reduce the stress placed on your unit:

  1. AC is refusing to turn on. You’d think that with all of the technology we currently have at our disposal, we would be able to find a simple solution to the unit that won’t turn on. Most commonly, an AC is not becoming triggered to start due to a malfunctioning thermostat, a lack of power, tripped circuit breaker, or loose wiring.

  2. Your unit doesn’t have enough refrigerant. Your unit may be working day and night to “cool” air inside your home, but it never seems able to keep up with the sunny onslaught outdoors. Your unit can lose refrigerant over time, but there is also a possibility that there may be a leak somewhere, which is a serious problem. Get an experienced technician on your property as soon as possible to address the possibility of a leaking unit.

  3. Your unit has a frozen evaporator coil. A unit with poor airflow can cause an evaporator coil to freeze up; in this case, your AC unit may run, but it will not cool anything properly until conditions are ripe for the evaporator coil to thaw out once more. This is not a problem that can be ignored either; call out a technician to see if the underlying cause is with the unit itself or with the fans in your HVAC system.

  4. Your system may have blocked air ducts. We’ve all had the experience of needing a sweater in one room and needing a towel in another. You know your unit is cooling, but it’s unable to circulate through the home properly due to blocked ducts. Ductwork should be regularly maintained and cleaned to reduce the possibility of blockages; if you suspect that this is your issue, an HVAC technician should be able to address and remove blockages fairly easily.

  5. Your unit is “noisy.” A properly installed and properly working HVAC unit should be relatively quiet; if you hear banging, clanging, squeaking or whistling noises, this is likely due to a malfunction with your fan system in your external unit or internal unit. It’s only a matter of time before your fan blades, belts, and bearings will give out and lead to more expensive repairs. If you hear any unusual and alarming noises coming from your unit, turn it off and contact an HVAC to schedule a repair ASAP.
