Many people do not think of heating and cooling as very important in their homes. However, when heating and cooling systems malfunction, people realize just how important they have been all along. If you are in need of heating and AC repair in the city of Dallas, TX, you will definitely want to contact a reputable company in order to take care of your heating and cooling needs.
There are many different problems that occur and require heating and AC repair. There are many common issues that occur with heating and cooling systems that can seriously inconvenience you and require you to call in the professionals.
Common Problems with Heating Systems
Forced air furnaces can often encounter issues. Whether you have a conventional or high-efficiency forced air furnace, they generally all work the same way. They take in cold air and distribute the warm air throughout the ductwork of your home via a blower motor.
Once the heated air is released into your home, it cools down and returns back to the furnace through ductwork and air grills. This cold air will go back through the air filter and into the furnace. Once it is here, it will finish another heating loop. In some cases, there will also be a humidifier that is mounted on the furnace or within the return air ductwork.
Generally speaking, conventional furnaces have simple designs. However, there are situations where they do not operate properly. In these situations, you might need to call in a Dallas, TX heating and AC repair professional for help.
Not Enough Heat
When cold weather starts, it is very important that your furnace is properly working. It needs to be creating enough heat to warm up your home. If it blows only cool air or doesn’t produce heat, there are several potential reasons for this. In some cases, you will be able to repair the system on your own, while another is, you will have to consult with a heating and AC repair professional.
There are few things that you can try on your own before bringing in a heating and AC professional. You can make sure that the heat registers are open, check thermostat settings, and make sure that the furnace actually has power.
Furnace Cycling On and Off
If your gas furnace is frequently switching between being on and off, this can cause damage to your furnace and drive up your energy bills. When the weather is very cold, this might actually be normal in order to keep your home at an optimal temperature. However, if this is not the case, there could be some real problem with your furnace. Potential causes include a blocked exhaust vent, a dirty filter, and a faulty thermostat.
Constantly Running Blower
If your furnace blower is constantly running, there are two likely reasons for this.
It could be that the thermostat is set to the fan setting. If this is true, it will wear out the blower motor. What you should do in this situation is change the blower settings back to auto, which will make it so that the fan is only running when the system is actively heating or cooling.
Alternatively, you might have a faulty fan limit control switch. The fan limit switch is actually a safety device that will monitor the temperature in the interior of your furnace. When the components reach set temperatures, it will automatically shut them off. If the blower is consistently running, it may signal a malfunctioning limit switch. In order to deal with this problem, you can reset the switch or potentially replace it if it is actually damaged.
If there is too much noise in your furnace, it almost always means that there is some sort of problem that can become very significant if you allow it to go on. Sometimes, you will hear loud banging, sometimes it will be low pitched humming, and sometimes it will be a very high squeal. In some cases, you will be able to address the issue yourself, but in many cases, it will be a good idea to bring in a heating and AC repair technician. Bringing in a technician right away will often save you money in the long run because they will be more likely to be able to pinpoint the problem and fix it.
Pilot Light Not Working
The standing pilot light can go out on an old furnace for a few different reasons. This could be because of dirt that is lodged in the gas tube, a dirty orifice within the pilot burner, or some sort of strong draft that has blown out the light. In some cases, there could be a faulty thermocouple that causes the gas supply to shut off.
Failing Electronic Ignition
If you have a newer conventional furnace, it won’t rely on a standing pilot in order to ignite gas burners. Instead, they typically utilize electronic components. Usually, this means either hot surface or intermittent pilot ignition. The hot surface ignition system will use an electronically-controlled resistant heating element to start ignition of the gas burner. If you have an intermittent pilot system, it will use an electronically-controlled high voltage electric spark in order to start ignition.
If there’s a problem in the electronic ignition, it could cause many issues with your furnace. Sometimes, you will be able to fix them yourself, while other times, you will have to call in a Dallas, TX heating and AC repair professional to do the job.
Mismatched Thermostat and Furnace
Your thermostat and furnace need to be correctly paired in order to function properly. Sometimes, your furnace might under heat or overheat your home if you don’t have the right thermostat. A heating and AC repair technician can help you find the right one.
There are many different issues that you can observe as a result of a faulty thermostat. Sometimes, the furnace won’t produce any heat, sometimes the temperature will swing back and forth in an extreme way, and sometimes the furnace will cycle on and off very frequently. You should make sure that your thermostat is adequately powered and that there is no debris within the components. If you notice that there are no issues here and it is still not working, you should consult with a heating and AC repair professional.
Common Problems with AC Systems
One of the most common problems with air conditioners involves improper operation. Basically, if you have your air conditioner turned on, you should make sure that the windows and doors are closed. If you have an air conditioner in one room, you should try to isolate that area from the rest of your home as much as possible.
There are also many other common issues that can arise with air conditioners. Some of these are due to faulty installation, summer due to inadequate maintenance, and some are actually due to poor service procedures that have been done by incompetent heating and AC repair professionals. If an air conditioner has not been installed properly, this can result in low airflow and leaky ducts. A lot of the time, there needs to be a certain amount of refrigerant in the system that is not there. The refrigerant charge, which is the amount of refrigerant that exists in the system, needs to match the specifications laid out by the manufacturer.
When the air conditioner is installed, proper refrigerant charging needs to be performed. Otherwise, the unit is not going to be operating at maximum efficiency, and its performance will be impaired. This is often an issue when you bring in an unqualified service technician. A lot of the time, they won’t be able to find refrigerant charging issues, and they can sometimes even exacerbate existing issues. For example, some of them will add refrigerant to a system that is already full of refrigerant. This is one reason why it is very important to bring in a qualified heating and AC repair technician when you have these sorts of issues.
Generally, the manufacturers of AC systems make high-quality products. If your air conditioner is not working, you should start out by checking circuit breakers and fuses. Allow your unit to cool down for at least 5 minutes before you try to reset any of the breakers. If the compressor stops when it is really hot outside, it is possible that the high-pressure limit switch has tripped. if this is the case, all you need to do is try to reset it by pushing the button that is located within the access panel of the compressor.
Of course, there are a few things that you should know about the most common issues that can arise with a faulty air conditioner and potentially require heating and AC repair technicians.
If your air conditioner doesn’t have enough refrigerant, it is either leaking or it was undercharged during the installation process. If it is leaking, it’s not going to work to simply add refrigerant. A trained heating and AC repair technician should be able to fix any leak. They should also be able to test the repair and then charge the system with the appropriate amount of refrigerant. You need to remember that the efficiency and performance of your air conditioner will be at its peak when the refrigerant charge is exactly as the manufacturer says that it should be.
This means that the refrigerant should be neither overcharged nor undercharged by the heating and AC repair technician. It is also important to keep in mind that refrigerant leaks can be very harmful to the environment, as well as your home.
Your air conditioner will be at its best if you maintain it properly. This means that you should not allow air conditioning coils and filters to become dirty. If this happens, the fans and the compressor are more likely to fail before you are able to get your full use out of them. This is something that you should pay attention to, so that you don’t need to unnecessarily call in a heating and AC repair technician for a problem that could have been avoided entirely.
Electric Control Failure
Another common problem with air conditioners that can require the enlistment of a heating and AC repair technician involves electric control failure. In some cases, fan controls and compressors can wear out. This is particularly likely when you turn your air conditioner on and off on a frequent basis. This is very common when a system is oversized.
When you bring in a heating and AC repair technician, you should have them check all of the contacts and electrical connections. This is because the corrosion of terminals and wires can be a common problem in these sorts of systems.
Air conditioners in rooms include thermostat sensors. These are oriented behind the control panel. The purpose of the sensor is to measure the temperature of any air that enters the evaporator coil. If the sensor is moved out of position, the air conditioner can sometimes misbehave or constantly cycle.
The correct position for the sensor is near the coil without touching it. If you see that it is not in this position, you should carefully adjust it by very carefully bending the wire that holds the sensor in place. If you do not feel confident to do this yourself without causing damage, you should bring in a heating and AC repair technician in Dallas, TX to do the job.
Sometimes, when it is very humid outside, the condensate drain can become clogged. You should check it to make sure that there aren’t any clogs, and that it is doing its job properly. If you have room air conditioners that are not mounted level, they may not drain properly. If you have any questions about what you should do about draining issues or how to solve them, you should bring in a heating and AC repair technician to examine your system.
