BOOST YOUR HVAC UP TO HIGH LEVEL

Most wall or central AC units are quite sturdy, and good for years or even decades of service. If it simply fails to turn on one day, the first thing you should check is the fuse or circuit breaker that supplies the unit. If the fuse is blown or the breaker is tripped, you have probably found the trouble. AC’s can draw a lot of power, and if other appliances are running on the same circuit, the fuses or breakers are set to shut the circuit down before the wires can overheat and start a fire.

Let the unit cool down for at least 5 minutes, turn off all other devices on the same line, and reset he breaker or replace the fuse. Turn the AC back on. If it runs, all is well – simply try to avoid over loading that line while it is on. If the breaker or fuse goes again, you may have a more serious problem, and should call a repair person or electrician.

Too little coolant, or the wrong type of coolant :

If the refrigerant charge has fallen below normal operating levels, your AC will not function efficiently. If it has been recharged improperly – either to too high a pressure or with the wrong kind of refrigerant, the unit may not work at all.

To avoid this, always use a qualified professional like “Ac Repair In San Jose” to recharge and maintain your AC’s coolant. Poorly qualified technicians can even make the problem worse (and more expensive to set right).

Poor or infrequent maintenance :

Failing to clean or replace filters, or allowing the evaporator or condenser coils to become dirty can lead to poor performance, and even contribute to the premature failure of your air handling unit or compressor fan.

Clean the filters monthly during hot weather, and the coils at least once a season for best effect.

Coolant leaks :

If your air conditioner is low on coolant, you most likely have a leak in the system. No AC system can be permanently leak-proof, and this is something that can be fixed, often inexpensively – but only by a professional. “Ac Repair In San Jose in Hyderabad” will be happy to send a repair person out to test the system, fix any leaks, recharge it with the proper coolant, and verify that the system is working properly.

Better still, you might notice a big efficiency improvement, as most AC’s work at their peak with just the right levels of coolant.

Electrical failures :

Your AC system has just as many electrical and electronic components as mechanical ones. Fan or compressor controls, switching systems and thermostats can all fail over time, and contacts or connections can become corroded.

A trained technician can identify this, repair the problem, and perform preventative maintenance of the rest of your electrical components so that it doesn’t happen again anytime soon.

Sensor and thermostat issues :

Most AC’s, central or window-mounted, rely on a thermostat to maintain a specific temperature range. Part of the thermostat is a temperature sensor which tells the unit how warm the air in your home actually is. If this component begins to fail or give false readings, your system will begin to turn on and off erratically, and fail to maintain a comfortable temperature – either far too warm or too cold.

If you believe this may be the issue, call a trained repair person or technician, as they will be able to diagnose and repair or replace the thermostat quickly.

The wring size of window-mounted air conditioner could be the real problem :

Window air conditioners are different from central AC units, in that they really do need to be sized specifically for the room they are cooling. Wall-mounted air conditioners might be rated at as little as 5,500 BTU/hour, or as much as 14,000 BTU/hour. Their capacity in India may also be measures in ‘tons’ – a ton in this case is 12,000 BTU/hour.

If the unit is too small for the room, it will never be able to cool it properly on hot days. Alternatively, if the unit is too large, it will be forced to turn on and off frequently, reducing its power efficiency dramatically, and causing undue stress on its electrical systems.

An oversized unit is also likely to be louder than a smaller unit, and will be less effective at dehumidifying the room, not just cooling it.

You can choose the right AC unit size by allowing 20BTU/hour for each square foot of space. Of course, this varies, and a sunny, southern-facing room in India might easily require 40 BTU/hour per square foot.

When it’s time to call a professional :

A skilled DIY enthusiast can do many of these jobs, but not all of us are so inclined. Many more of us probably could spend a few hours researching an AC problem online and then a few more fixing it – but can’t afford to miss a day off work. Most of us would simply prefer the peace of mind – and insurance advantages – of having a qualified professional tend to our AC Repair!
