Your AC’s Refrigerant and Signs It Might Need Attention
Your air conditioner’s refrigerant is a chemical that creates a cooling effect as it absorbs and transfers heat and humidity out of your home. Sometimes, it might need to be topped off as part of regular maintenance. The following are signs that this might the case with your air conditioning unit:
- It takes longer than usual to cool off your home
- Warm or lukewarm air, and not cool air, is blowing through your vents
- The temperature you set on the thermostat is never reached
- You notice ice or water in or around your air conditioning unit
Note that refrigerant is very dangerous and should only be handled by a professional during a scheduled AC repair appointment. Furthermore, if you observe hissing sounds while your air conditioner is on and running, and it’s in tandem with any of the above symptoms, you might have a leak that needs to be repaired as well as part of AC repair by a professional. Just topping off the refrigerant, in this case, will not suffice.
If Your AC Doesn’t Start, the Compressor Might Be to Blame
If you hear your AC unit making loud rattling, banging or thudding sounds, turn it off — the compressor might need to be looked at by a skilled technician during an AC repair call. An air conditioner’s compressor is the component responsible for circulating the coolant, or refrigerant, which is talked about above. In addition to making noise, a faulty compressor might also result in the following:
- A feeling that the unit is vibrating excessively, more than it would during normal operation
- The electrical breakers linked to your AC unit are flipping
- Poor airflow through the vents in your home
- The unit experiences issues starting or doesn’t start at all
There are a few things you can do to troubleshoot your air conditioner’s performance and determine whether or not the compressor is in need of repair or total replacement. However, it may very well be that the breakers or wiring needs to be looked at in addition to the compressor. If your air conditioner starts making loud noises or exhibits any of the above symptoms during a hot summer, call One Hour Air Conditioning & Heating of Dallas to schedule an AC repair right away.
Your AC’s Coils Could Use a Good Cleaning
Your air conditioner has two coil components that a professional will check out during a routine tune-up or during an AC repair job. The evaporator coil, which is located on the indoor portion of your cooling system, removes the heat and humidity from the air inside your home and cools it. Whereas the condenser coil, located outside, takes the removed heat and humidity and forces it out of your home. Often, the signs and symptoms of an evaporator coil and condenser coil not functioning properly, are similar to the symptoms caused by other broken or malfunctioning components of your air conditioner. This can include unusual noises or a marked reduction in your unit’s ability to cool your home. In many cases, the coils need to be cleaned, something that can be done safely and using the right methods by a skilled technician during an AC repair visit to your home.
A Faulty Expansion Valve Can Cause Several Problems
The expansion valve is responsible for regulating the flow of refrigerant in your air conditioning system. As with coils, many of the symptoms of a bad expansion valve, like noise and poor cooling, can be attributed to other issues as well. However, one thing that is often linked to a faulty expansion valve is an air conditioner that will not shut down once the temperature set on the thermostat is reached. This may indicate that the expansion valve’s temperature detection is not working, and this is something that can be confirmed through professional AC repair services by One Hour Air Conditioning & Heating of Dallas.
Furthermore, this excess running due to a faulty expansion valve can wear out an air conditioner’s compressor. If you suspect there is a problem with your expansion valve, it is crucial to get it repaired or replaced because it is much cheaper to take care of a malfunctioning expansion valve than it is to replace a worn-out compressor. The good news is that scheduled maintenance of your air conditioner can detect an issue with an expansion valve long before it impacts a compressor. However, if this is a new development and you can’t wait until your scheduled tune-up, call for emergency AC repair to get help from one of our responsive and experienced technicians.
With hotter weather around the corner, you need to be sure your air conditioning unit is fit to keep you cool in the coming months. If you suspect that any of your AC unit’s components are malfunctioning, don’t risk further damage to your cooling system.
