When Should You Call for AC Repair?

At Michael Bonsby Heating & Air Conditioning, we can provide air conditioner repair for any issue you may have or offer a cost-effective replacement  if your unit is over 10 years old and beyond repair. Some of the most common air conditioning issues we see include:

Low Refrigerant

Air conditioner refrigerant is installed in a closed loop, so if you have low refrigerant it either means your system wasn’t properly charged at installation or you have a leak. An experienced technician from Michael Bonsby Heating & Air Conditioning will fix the leak, test the repair job, then charge your air conditioner with the correct amount of refrigerant.

Remember: the performance and efficiency of your air conditioner is greatest when the refrigerant charge exactly matches the manufacturer’s specifications and is neither undercharged nor overcharged. Refrigerant leaks, particularly in older systems, can also be harmful to the environment. So if you have a leak, call us today!

Poor Maintenance

The most important thing you can do to keep your AC running smoothly all season long is have regular air conditioner maintenance done. If left unchecked, things like clogged filters and dirty coils will prevent your air conditioner from working properly and will likely cause your compressor or fans to fail prematurely. If your air conditioner is starting to fail because you haven’t had proper maintenance, call Michael Bonsby Heating & Air Conditioning today for air conditioner repair!

Electric Control Failure

Air conditioners have sensitive electronic controls that need to be maintained properly. For example, if your system is too big or too small, the compressor and fan controls may wear out prematurely. Wires and terminals may also suffer from corrosion, which may cause you to need air conditioner repair for your DC area home.

Air Conditioner Repair FAQs

Why does my air conditioner make so much noise when it starts up?

All air conditioners make noise when they first start – the oil needs to get through the system and the compressor needs a few seconds to get to the right pressure. These noises should only last for a few seconds – if they last any longer than that you should call Michael Bonsby Heating & Air Conditioning for an air conditioner inspection!

Why is ice forming on my AC refrigerant pipe?

If your air conditioner coil is frozen there could be a number of factors at work. Usually the coil is frozen because your filters are dirty and are blocking airflow through your AC system. This would cause cool air to condense around the coil, which would be frozen since the coil is so cold. If your filters are not dirty, you may have the wrong level of refrigerant or a clog in your refrigerant line.

Why is water dripping from my AC coil?

If condensate is dripping from your AC coil, this means that your air conditioner is either improperly charged with refrigerant or improperly insulated. Having the proper level of refrigerant in your AC is crucial to maintaining the health and efficiency of your unit. Not only that, but too much condensate that forms on your coil could eventually freeze, leading to even bigger problems. If you have water on your pipes, call Michael Bonsby Heating & Air Conditioning for an air conditioner tune-up.
