Solutions To Common Air Conditioning Problems

common air conditioning problemsThe science of climate control may seem fairly complicated, these solutions to common air conditioning problems can save you plenty of trouble and probably add years to the life of your air conditioning unit, too. Most air conditioners simply stop running efficiently and you end up running them longer and turning the thermostat down even lower without achieving the climate control results you want. Soon enough, that’s insufficient and you repeat the process until you realize that the unit is simply not cooling and not going to cool. It may even run hot.

These common air conditioning problems are things you should watch for well before your air conditioner runs down and simply stops providing any climate control at all.

Water Leakage – All air conditioners can leak water and while this can cause significant problems in your home, it can also damage the air conditioner itself. A rusted out condensation pan or pipe can be the problem and it’s often very easy to replace. More simply, bits of rust or other debris can also block the drain or hose leading from the drain. Make sure all the drain parts are clear.

Frozen Coils – Frozen coils will very often indicate problems with the airflow into the air conditioning unit. In most cases, this is dealt with simply by replacing used air filters. Blocked air vents or ducts could also free up frozen coils and get the air conditioning flowing again. Low refrigerant or low freon pressure are less common air conditioning problems but will cause a bottleneck in the air conditioner and possibly the same frozen coils. Either refrigerant or pressure need to be adjusted according to the manufacturers specifications, mostly likely by an air conditioning specialist.

Fan Problems – Your air conditioner fan is working to move the heat from inside your home to the outside. When it’s not operating efficiently it will quickly overheat and trip the safety switch or the circuit breakers. It can even cause damage to the compressor or another part of the circuitry of the air conditioner. Most common air conditioning problems tend to start with a noisy fan. Loud noises almost always begin with the the fan belt that simply needs to be replaced. The manufacturer may also recommend lubricating the fan and the motor bearings which can also be the source of noise.

Temperature Controls – Air conditioning units can also seem to simply shut off without providing any climate control or much cooling. Air conditioners with blocked input vents or grills usually display such temperament though there may be more serious problems. Carefully cleaning the vents and taking the air conditioning unit apart to clean hard to reach areas will solve most of these problems, though .

Wiring Problems – Air conditioners are also often short-circuited to the ground which will cause the circuit breakers to fail. Most likely this is a problem that needs to be addressed by a climate control professional.

Air Conditioning Maintenance and the Life of Your Unit

Whether you have a window mounted unit or a complete central air conditioning system, maintenance is the key to the long life of your HVAC system and desired room temperature. Whether it’s a small unit from an obscure foreign factory, or one of the finest Carrier Corporation models, regular air conditioner maintenance is easy and saves you money on running the unit and on using the least possible amount of energy to stabilize and maintain a comfortable room temperature.

air conditioning maintenance tipsIn addition to a higher electricity bill, a poorly maintained air conditioner can also aggravate sinus congestion, headaches and allergies. These maintenance tips are intended to extend the life of any air conditioning unit and to get it running more efficiently and effectively while providing you with comfortable room temperature on those sweltering days in NYC.

1. Replace air filters at least every 3 months. Pleated air filters are generally recommended and they’re as important for your air conditioner as changing the oil and filters in your car. People with allergies might want to replace filters every 6 weeks. Make sure you carefully check the direction of the filter, as many models are oriented for insertion and use in only one direction. Any airflow vents should also be inspected for obstructions or dirt build-ups or blocking.

2. Check the thermostat. Don’t set it to a ridiculously low temperature. It usually just makes your air conditioning run longer but without actually dropping the room temperature. Obviously, the electricity use will be much higher, too. You also want to annually make sure that all of the controls operate correctly.

3. Inspect the ductwork. And patch it with duct tape if necessary. Window mounted or smaller units need to be unobstructed with a clear area for ventilation. You’ll also want to protect smaller units and any entry or exit points of your ducts during construction.

4. Insulate. Insulating your ducts keeps the cool air inside while it’s traveling. Foil backed insulation wraps will improve the efficient delivery of colder air to all the parts of your house where you need it.

5. Clean outside. Thoroughly clean and inspect your outside air conditioning unit or heat pump at least once per year. Any blocked air vents will cause the air conditioning unit to work harder, raise energy consumption and reduce the life of the unit.

6. Tighten all electrical connections. Have your ac service technician should measure the voltage and current on the motors. Faulty electrical connections will reduce the life of the air conditioning unit and could lead to unsafe operation.

7. Lubricate any moving parts. Motor friction will seriously reduce the life of any AC unit, so you’ll want to speak with a technician about properly lubricating your machine.

8. Check the Drain. A central air conditioner, or a heat pump in cooling mode needs a clear, operable drain, and can provide an ample source of free distilled water.

9. Clean the coils. Dirty evaporator and condenser coils will reduce cooling efficiency and can cause odors and unpleasant, inefficient operation.

10. Refill the refrigerant level if necessary. Ask your service technician how if you’ve never done it. Too much or too little refrigerant will impair the efficient operation of your air conditioning system and it will also severely reduce the life of the unit.

No matter the make or model of the air conditioning you’re running, your room temperature and ultimate comfort depend on a regular maintenance schedule. Contact us now at 646-783-2478 to schedule air conditioning maintenance.
