We know you need an AC you can depend on.

Picture of a man plugging his ears.

Hot spells can strike any time of the year, even during the wintertime when much of the northern states have thick blankets of snow. If your AC starts sending you signals that it could be struggling or heading towards a malfunction, you might want to act quickly to make sure things are fixed quickly. You do not want to find yourself among those surprise warm days that are coming. You also could get a worse surprise when the air conditioning system refuses to come on all together. However, even if your AC fails completely, you don't have to panic: Best Owner Direct HVAC is ready to take care of your air conditioning needs. Our NATE-certified specialists will do everything possible to not allow you to do without the required convenience of your air conditioner.


Is that grinding sound from my air conditioner an indication? Strange sounds are among the warning signs to look out for to tell if your ac system is experiencing a problem. You are most likely accustomed to the audio your air conditioner makes during the normal functioning, so when something like a grinding sound begins, it will stand out-- as it should. A few of the major root causes of this pesky grinding sound we see on a routine basis consist of: Problem with the compressor: This is the number one probable cause of this concern. This crucial element is what sends out the refrigerant through the ac unit's lines and also permits warm exchange. Compressors operate similar to motors, with pistons that press the cooling agent inside. If the compressor wears down, the pistons can begin to cause an undesirable grinding sound. Various other inner components may have been damaged or come loose. Generally, the compressor will certainly need a complete replacement, which is a job trained cooling and heating specialists can get done for you. The blower follower belt has come loose: Sometimes, this element comes loose and starts to press against various other parts of the ac unit's cupboard. The harmed belt will certainly need to be transformed prior to it causing further difficulty for other components. This isn't like transforming the motor belt in a car: it requires unique expertise as well as the right tools. Absence of Electric Motor Lubrication: Sometimes with older devices. The electric motor needs additional lubrication to remain running efficiently and silently. While this is a tiny fix if you catch it early, with time it can create a lot of damage to your air conditioning's motor.


Please remember that your air conditioning unit may still seem to work generally even with these troubles taking place. Don't find yourself getting used to the grinding sound or trying to ignore it-- the problem will certainly not disappear, and also it will become worse until a major breakdown occurs that will require expensive repairs. When you listen to these grinding sounds, hire cooling and heating specialists that will be able to identify where the issue exists and also fix it so it won't repeat. Best Owner Direct HVAC can help you with any type of problems you may come across with your cooling system. Grinding sounds, frozen coils, weird scents from the vents, etc. If you believe there's something awry with your AC, contact us right away.
