Common Summer Air Conditioner Problems

It’s summer, and suddenly your air conditioner stops working. There are a few things as frustrating as this and you need to find a quick solution. While many AC repairs require the input of a professional, there is no harm in knowing about some of the problems that occur during summer and understanding how you can fix them. Being aware of the most common AC issues that occur in the summer can save you plenty of time and effort when the system needs to be serviced.

air conditionerAC Won’t Turn On

If the AC stops running, check that it’s properly plugged in. If so, ensure there is no tripped circuit breaker or blown fuse. Restore the power and see if it works. Another potential cause is usually that the thermostat isn’t working or that it’s set improperly. Check the thermostat settings and if this doesn’t help, it may be time to replace the thermostat altogether. Before rushing to replace the thermostat, check that the air conditioner’s break box isn’t flipped.

AC Stays On Not Long Enough or Too Long

Where you place your thermostat ultimately determines the length of time your AC will run over the summer. Placing the thermostat in direct sunlight can cause it to run for extended periods of time even after room temperatures are down to comfortable levels. Changing the thermostat’s location will improve overall efficiency as the unit will only be forced to run when it’s necessary. Installing a programmable thermostat, in case you don’t have one already can further lower your cooling costs.

Inadequate Air Cooling

If your AC doesn’t seem to be cooling your home as well as it used to, start by lowering the thermostat a few degrees. If that doesn’t work, you may have a clogged filter. Inadequate air cooling usually indicates an airflow problem. If it’s been long since you last changed the filter, consider having it replaced as it could be restricting air that’s trying to get back into the AC. For optimal functionality, check that the AC has sufficient clearance all around. Anything within about two feet of the unit could be hindering the free flow of air.

AC Runs But Doesn’t Cool

If the AC is running but not cooling the house, still check the thermostat. You should then take a look at the condenser. The condenser can be blocked by grass, weeds, or other airborne debris. If it’s blocked or dirty, clean and remove any blockages. An inadequate amount of refrigerant or a faulty compressor can also be the cause of an AC that doesn’t blow cold air. In this case, you should contact a reputable HVAC company in Huntsville to address the problem.

Unusual Noise When AC is Running

Hearing strange noises every time your AC starts up or turns off could be an indication of blower issues. However, sometimes it may just be a loose screw. Tighten the loose screw and check if the noise disappears. Dealing with high voltage appliances can be very dangerous, so it’s best to call a professional. If you must handle any issue on your own, shut off the power to the AC before touching any components.

AC Costs Too Much to Run

For some people, summer is synonymous with high cooling bills. In the case of poorly maintained units, energy costs can start to skyrocket over time. One of the best ways to cut down high cooling costs during summer is to have your AC serviced prior to the start of the hot period.

Refrigerant Leakage

Refrigerant leaks are a common occurrence in the summer and can prevent your AC from doing its job properly. When there isn’t enough refrigerant to absorb the summer heat, the vent is likely to blow out warmer air than normal. Signs that you may have refrigerant leakage include a much lower cooling output and accumulation of frost on the AC’s evaporator coils. An AC professional can check your system for leaks.
