Air Conditioning Repair: The Common Air Conditioner Problems That Require Professional Intervention

Posted on

A functional HVAC system is one of the best assets that you can have in your home. Efficient systems greatly improve the level of comfort inside your home and reduce your heating and cooling bills. An excellent system also minimizes the possibility that your home will suffer water damage, mold infestation, and rotting. As you continue using your unit, you may notice a drop in its efficiency. Sometimes, it may be a minor problem that needs a tune-up. At other times, the system might be broken, needing a competent HVAC professional for repairs. 

If your system has these three problems, you should call an AC repair professional for help.

When the Unit Fails Run

It can be unsettling to switch on your air conditioning system and get no response from it. HVAC units stop turning on because of simple or complex problems. For instance, the problem could be a blown fuse or tripped breaker. An HVAC repair professional will help you find out what led to the fuse blowing.

Other typical reasons why your AC might not be running include a damaged thermostat. The thermostat may stop running due to a faulty thermostat cable. A professional will replace the thermostat with a new one so that the unit can resume its normal function. The AC specialist will also change the cable to avoid future short-circuiting.

When the AC Turns On But Doesn't Cool

The AC can lose its cooling function for several reasons. Sometimes, one or more of the vents and registers could be blocked. When the warm air from the room mixes with cold air from the vent, you will not feel the impact of the cooling. Vent blockages can be remedied by simply removing the blockage. 

A more serious cause of cooling complications is a leak in the refrigerant. You will need to hire a professional to repair the cooling system and replace the leaking parts. Also, the HVAC technician will check for problems with the fan and motor for repair or replace them to restore your unit's efficiency.

When the Fan Inside the AC Stops Working

The fan stops working when the coil is frozen. The coil may freeze when water in the system solidifies into ice. The only repair for this is changing contacts inside the fan relay or the belt. A reliable AC repair contractor will inspect your fan and offer the best solution. 

Competent and experienced HVAC repair technicians will inspect your system for broken parts that need repair. As soon as they fix them, your unit will resume its function, which will boost comfort and air quality in your home.
