The 4 Most Common Central Air Conditioner Problems

Annual Maintenance is the Key To Staying Cool

Crestwood air conditioner maintenance

With the hot, humid weather right around the corner in the Crestwood area, now is a good time to have your central air conditioner maintained. Most of the air conditioner problems we see every day are the result of lack of maintenance and not having the AC unit regularly inspected.

1. AC Refrigerant Leaks

A central air conditioner should not lose coolant during normal operation. There are a couple of reasons an air conditioner may be low on refrigerant – either it was not sufficiently charged when it was installed, or it has developed a leak. Your HVAC technician will look for leaks in the system and refill the unit with refrigerant if needed. The amount of refrigerant added to the unit must match the manufacturer's recommended amount to ensure optimal cooling performance. If a leak is found it's best to find the cause of the leak and make repairs before adding more refrigerant.

2. Clogged Furnace Air Filters

An air filter should be replaced monthly, or as recommended by the filter manufacturer. When filters become dirty and clogged the AC unit must work harder, and parts such as the compressor or fans are likely to wear out prematurely.

3. Dirty AC Coils

Evan a small amount of dirt accumulating on coils can significantly reduce the cooling performance of your air conditioner. AC coils should be cleaned to prevent the accumulation of dirt and debris. Before performing any maintenance always be sure to shut off the power supply to the unit.  Gently vacuum the fins and coil to avoid bending the metal. Never use a power washer to clean an air conditioner. Keep the area around the air conditioner free of tree branches and bushes to keep debris from falling on the unit.

4. Air Conditioner Electrical Component Failure

Compressor and fan controls will wear out over time, especially when the air conditioner turns on and off frequently. If your noticing that the AC is cycling on and off more frequently, or is running much longer than usual, give us a call to inspect the unit. Corrosion of wires and terminals is another common problem in many systems, so the electrical connections and contacts should be inspected annually during AC system maintenance.

By regularly maintaining your air conditioner you can keep your air conditioner running as efficiently as possible, while also saving money on unexpected breakdowns and repairs.

Central Air Conditioner Noises

Written by
Central air conditioners have a lot of moving parts working to keep your home cool and comfortable. Over time, the parts will wear out and lead to a variety of sounds you may not have heard before. Some of these sounds can be easy to identify and fix, like a loose panel cover, or could be a sign of a bigger problem like a worn out condenser motor.

Air Conditioner Noises

Air Conditioner Rattling Sounds

Rattling sounds are a fairly common with air conditioners. Over time the various fasteners attaching components to the unit can become loose. If you hear a rattling sound, check the screws or bolts on the cover plates. If the rattling noises is still heard after tightening the panels, remove the cover and check inside the unit for the loose panels. After listening for rattles, always turn the power to the unit off at the breaker.

Central AC Whistling Sounds

Whistling sounds are usually a result of faulty seals. Check for cracks and gaps in the seams of ducts near the AC unit and in the duct work that carries the air throughout the home. Examine the seams around these areas for loose connections and re-tighten any loose screws or bolts. If tape was used to cover the seals, make sure the tape is  adhering well to the duct seams.

Screeching Sounds

Like a car, an air conditioner motor uses belts to turn a fan. Over time the belt can stretch and wear out. If there is periodic screeching that only occurs when the unit turns on to blow air or cool the air down, it is likely a worn-out belt that needs to be replaced. A qualified HVAC technician should check the belt and replace it if needed.

Clunking Sounds

Clunking sounds can mean a part has come loose inside the AC unit. A loose fan blade on a motor will often make sounds as it turns. It may also be that a plastic component or cover plate is coming into contact with the fan. A qualified HVAC technician should inspect the unit to ensure it is operating safely.

Is Your Sump Pump Ready For Spring?

Written by
Sump pumpWith the spring thaw and rain showers, water can begin to seep into foundations, causing basement flooding. Many homes in the Chicago area will experience some amount of ground water seepage inside. Even a little bit water seepage into the home can cause damage by creating an environment for mold and mildew to grow inside walls, causing health concerns. In severe cases, water can cause damage to your home and property. The first line of defense from basement flooding is a sump pump.

Sump pumps are small electric pumps installed in the basement or crawlspace of a home. It is often placed in a sump pump pit to allow water to drain below the floor level.  As the pit fills with water, the pump turns on automatically to move the water out of the pit through a drain pipe that exits the home. The drain pipe has a check valve near the pump to keep the water from flowing backwards and returning into the home.

Because flooding is most likely to occur during severe weather and electrical storms, power to the pump could be unavailable. For peace of mind, consider a battery back-up sump pump, which can operate for hours, even when the home's electricity is off.

Testing Your Home's Sump Pump

Most homeowners don't think about their sump pump until a problem arises. But by testing your sump pump regularly you can ensure that it will be there when you need it most. Here's how to test your home's sump pump.

1. Fill a large bucket with water.
2. Slowly pour the water into the sump pump pit.
3. The pump should turn on and remove the water.

If the sump pump does not turn on, ensure that the pump is plugged into an operable power supply. If the pump still doesn't work, call M/R Plumbing to have the sump pump unit unit tested and repaired replaced if necessary.
