Air conditioning keeps everyone cool in the hot months of the year, but it’s important that each AC unit is serviced at least once a year before the really hot weather sets in. Over time, any unit will degrade in terms of performance, and it is good to understand when it might be time to call a local HVAC technician to either repair or replace it. Here are five signs your AC unit may need professional attention.
- Strange noises
Any air conditioner makes a noise when it is working normally, but it is usually not a good sign if it starts making wheezing, rattling, or popping noises. It could be as simple as a loose screw, but it could also indicate something more serious, like a faulty compressor.
- Inefficient cooling
As an AC device ages, it tends to cool down less efficiently, especially if it has not been serviced in a while. Anytime an AC unit suddenly stops cooling properly or doesn’t seem to be cooling as well as it normally would, something is usually wrong. In most cases, regular service and maintenance by a technician will fix the problem. However, sometimes the device needs to be completely replaced.
- The electricity bills are too high
The technology behind HVAC equipment just keeps getting better, resulting in more energy efficient equipment with a higher SEER rating. If it appears that your utility bills are higher than normal with the AC device running, it is likely not working efficiently and may need a technician servicing.
- It smells bad
Each HVAC unit has filters that need to be cleaned from time to time. The usual time frame is at least every three months as these filters trap pollen, dust, and other possible allergens.
Sometimes an AC unit becomes so clogged with dust and dirt, and the filter is so dirty and moldy, that it starts to smell when it is in operation. This is often a sign that there is mold or mold in the AC unit that needs to be professionally cleaned.
- Inconsistent temperatures
A fully functional alternating current can regulate temperatures with a built-in thermostat controlled by the user. If a device blows cold and then hot air, it may mean that the thermostat is damaged, the refrigerant is too low, or the compressor is damaged.
Bottom line – Regular maintenance is key
An AC device is designed to keep you cool during the hottest months of the year. However, if it does not do its job, it must be assessed by a professional Air conditioning repair Technician. Although the performance of HVAC equipment degrades over time, annual maintenance ensures that the equipment remains in good condition. This not only contributes to the proper operation so that the house stays cool, but also means that the device works cheaper.
