Welcome to the Air-conditioning

G&S Mechanical Services of Maryland 

We can service and repair your existing air conditioning system.

    There are literally thousands of air conditioning service and repair companies in the county; unfortunately most repair your equipment by telling you that you need a new one and how much money you will save by replacing your air conditioning or heat pump unit whether it works or not.

    We here at G&S mechanical believe that the customer is entitled to have their Air conditioning unit repaired unless it is just not cost effective, or if the unit is really damaged.  I personally feel that if the service person is not competent enough to tell you what is wrong with your equipment then they are not competent enough to sell you new stuff.

    Many of the larger companies including local utilities will take advantage of simple problems like burned off wires or bad contactors that can be repaired at a nominal fee.

    We have seen many cases where a system is leaking refrigerant 22 for many years and the leak is obvious (long term leaks usually leave tell-tale oil stains) and can be fixed easily instead of adding refrigerant constantly.

    We have seen situations were several different companies will simply keep adding refrigerant and charging the customer for it until the compressor is ruined. In one instance an accumulator tank on a heat pump was leaking for about 10 years and the company doing the service on the unit wouldn't tell the customer that it was leaking if they had then they couldn't keep adding refrigerant year after year. Leaks are not normal. This company was one of the top major companies in the Baltimore Washington dc. area, since Warner is out of the picture so I will leave it up to you to figure out who it is.

    Contrary to popular belief an air conditioner or heat pump only needs the correct amount of freon 22; adding more will make the system work harder and not cool as well.
