Some Clues to a malfunctioning Cooling System

If you think you may have a problem related to cooling your home, check out these common symptoms of a cooling system that may not functioning properly. Be sure to call for local air conditioner repair at 301-712-9530.

An air conditioner running all the time can have several causes including being low on refrigerant (freon). Its important to have your freon level tested by a qualified technician and to find the source of the leak if indeed it is low. Continuing operation could damage the compressor because it over heats due to low refrigerant.

Clogged condensate drains are a common cause of water leaking from your air conditioner. Freezing coils during operation could also cause water leaking around the furnace from the evaporator coil at the indoor unit. We recommend clearing the condensate drain line before the start of every season.

A buzzing noise at the outdoor unit is very common when there is an electrical issue with the compressor at the outdoor condenser. 

A loud noise coming from the furnace fan can be an indication of a bad blower motor. 

When the upstairs is hot all the time, or other areas in the home such as a bedroom not being comfortable. Upper levels are usually the first to suffer when you need an air conditioner repair.

Higher than normal electric bills during the summer months could be from an air conditioner that is using more electricity than normal and in need of a repair.

Ice on the air conditioner can be a sign of a frozen evaporator coil. Can be caused by a dirty filter, restricted airflow or the air conditioner low on freon.

Which AC Repairs are the most common?

Its no secret that Maryland has some extra hot summers. Our area is known also for having high humidity levels in the summer which causes our cooling system to work extra hard.  Luckily most breakdowns that occur are not that serious and are easily repaired.  

Below are some common failures as well as some recommendations. 


Common Residential Air Conditioning Repairs

Some of the most common repairs are usually simple electrical problems which can make the outdoor condensing unit trip the breaker or blow the fuse in the electrical disconnect. It is important to have the electrical components tested at the beginning of each season to avoid further damage from what was just a simple problem. It could save you the cost of grounded compressor.

Also many air conditioners are low on refrigerant (Freon) in which case the most common area for a leak would be at the service valves. It is also Common for freon leaks to form at the indoor evaporator coil. If your system is low on refrigerant, you will need to have a proper leak search performed in order to find the source. 

If you continue to run an air conditioner while it is low on freon, the compressor will overheat eventually causing a “Grounded Compressor”.

Clogged Condensate lines are caused by lack of Air Conditioning Maintenance. The seasonal routine of clearing the air conditioner drain can save your basement from flooding and even worse dripping through an attic ceiling.

It is a good idea to have a water protection device installed on your system especially if your unit is in the attic. There are many different types, and they are design to shut the system down when a back up occurs.

Our Automatic AC Maintenance Services Plans

Cooling System Maintenance Plans

A great way to avoid having Air Conditioner Repairs and ensure the safety of your family is with one of our HVAC Maintenance Plans.


Our Platinum Plan is by far our most popular choice as it includes Cleaning and Diagnostic Services that usually should be performed at each service visit. Choose this plan if your system is more than a couple of years old.

Our Gold Heating and Cooling Service Plan is a more economical choice that focuses mainly on Heating and Cooling Inspection and system performance. Choose this plan if you have recently replaced your system and it isn’t old enough to need cleaning. If you just want a proper heating and cooling assessment, this may the choice for you.

Benefits include keeping your family safe, lower utility costs, longer life of your cooling and heating system, and avoid excessive costs on repairs. Also save money on products and services as well as enjoying priority service. Be sure to compare our plans. Save having to deal with unnecessary water leaks from condensate back up.
