7 Tips to Stay Cool This Summer in South Florida

It's getting warm out and as the days pass it will only get hotter! Here are some tips to help drop the temperature in your home without raising your electric bill!

  1. Install a programmable thermostat to ensure you only pay for conditioned air during times you’re at home.
  2. Take advantage of the cool evening air by opening windows in the later hours and using a window fan to circulate air throughout the house.
  3. Turn the temperature setting up. For each degree over 78 degrees, you can save between 5 and 8 percent on your energy bill. 
  4. If keeping that dial higher is uncomfortable add a ceiling or floor fan. Fans make rooms seem about 5 degrees cooler!
  5. Keep the sun out during the day. Use curtains or blinds to block rays, particularly in rooms that get direct sun. 
  6. The right kind of light bulb will keep you feeling cooler!Switch out your incandescent bulbs for compact fluorescent bulbs which produce less heat.
  7. Indoor cooking with your oven can raise temperatures, making your A/C work even harder. Use your outdoor grill as much as possible, or cook indoors during the cooler part of the day.

For more great ways to save money on Air Conditioing consider routine maintenance, upgrading your system or cleaning your ducts! Contact GMC AC Services in Pompano for more information!

Earth Day Tips to Save Energy On Air Conditioning

Earth Day is April 22nd!

With that in mind, we have put together some great tips to help you save energy (and money!) on climate control!

Turn up your thermostat
Set your thermostat to 78 degrees when you are home and 85 degrees or off when you are away. Using ceiling or room fans allows you to set the thermostat higher because the air movement will cool the room.
Try installing an ENERGY STAR® programmable thermostat.

Replace air conditioner filters
Dirty filters restrict airflow and can cause the system to run longer, increasing energy use. Replace filters monthly for maximum benefit.

Get an annual checkup
If you have central air, consider an annual checkup. A professional, like GMC Air Services can diagnose any inefficiencies.

Use ceiling fans
Use fans to maintain comfortable temperature, humidity and air movement, and save energy year round. Moving air can make a somewhat higher temperature and/or humidity feel comfortable. Fans can help delay or reduce the need for air conditioning, and a temperature setting of only three to five degrees higher can feel as comfortable with fans.

Don't let the air out
Plug leaks with weather stripping and caulking to keep the cool air inside, where it belongs!

How Central Air Conditioning Works

Air conditioners and refrigerators work the same way. Instead of cooling just the small, insulated space inside of a refrigerator, an air conditioner cools a room, a whole house, or an entire business.

Air conditioners use chemicals that easily convert from a gas to a liquid and back again. This chemical is used to transfer heat from the air inside of a home to the outside air.

The machine has three main parts. They are a compressor, a condenser and an evaporator. The compressor and condenser are usually located on the outside air portion of the air conditioner. The evaporator is located on the inside the house, sometimes as part of a furnace. That's the part that heats your house.

The working fluid arrives at the compressor as a cool, low-pressure gas. The compressor squeezes the fluid. This packs the molecule of the fluid closer together. The closer the molecules are together, the higher its energy and its temperature.

The working fluid leaves the compressor as a hot, high pressure gas and flows into the condenser. If you looked at the air conditioner part outside a house, look for the part that has metal fins all around. The fins act just like a radiator in a car and helps the heat go away, or dissipate, more quickly.

When the working fluid leaves the condenser, its temperature is much cooler and it has changed from a gas to a liquid under high pressure. The liquid goes into the evaporator through a very tiny, narrow hole. On the other side, the liquid's pressure drops. When it does it begins to evaporate into a gas.

As the liquid changes to gas and evaporates, it extracts heat from the air around it. The heat in the air is needed to separate the molecules of the fluid from a liquid to a gas.

The evaporator also has metal fins to help in exchange the thermal energy with the surrounding air.

By the time the working fluid leaves the evaporator, it is a cool, low pressure gas. It then returns to the compressor to begin its trip all over again.

Connected to the evaporator is a fan that circulates the air inside the house to blow across the evaporator fins. Hot air is lighter than cold air, so the hot air in the room rises to the top of a room.

There is a vent there where air is sucked into the air conditioner and goes down ducts. The hot air is used to cool the gas in the evaporator. As the heat is removed from the air, the air is cooled. It is then blown into the house through other ducts usually at the floor level.

This continues over and over and over until the room reaches the temperature you want the room cooled to. The thermostat senses that the temperature has reached the right setting and turns off the air conditioner. As the room warms up, the thermostat turns the air conditioner back on until the room reaches the temperature.

Split System

A split system is an HVAC system in which some components are located inside the structure of the house and some are located outside. Split systems should be matched for optimal efficiency.

Dust and Your AC

If dust in your air conditioner made it more difficult and expensive to cool your home last summer, call an HVAC contractor to clean it for you. Although you can remove some of the dust yourself, you’ll need a technician who has the tools and training to access the parts that you can’t.

Dust is a major cause of air conditioning inefficiency and potentially failure. You can eliminate a good deal of dust in your air conditioner by keeping the filter clean for the indoor furnace or air handler. When dust builds on the evaporator coil, it slows the process of extracting heat from the indoor air, and may eventually cause the outdoor compressor to overheat and break. The dust also slows the passage of air through the filter, retarding the cooling process.

The other place where dust collects is in your outdoor compressor. Once you’ve removed all the vegetative debris around the unit, try hosing off the fins and coils with a light to medium spray. This can dislodge some of the dust that slows the cooling of the warmed refrigerant coming from inside.

An HVAC technician goes more deeply into the system by cleaning the outdoor coil and the electrical components. Dust impedes the flow of electricity through the wiring, interfering with the smooth operation of the appliance. The technician uses pH balanced cleaners to remove all the dirt and dust from the compressor’s coil, as well, increasing the efficiency of your A/C.

He also cleans the evaporator coil indoors and measures the amount of refrigerant in your system. The dust that collects outdoors can cause tiny leaks in the coils and connectors. If the refrigerant is low, the technician looks for the leaks and repairs or replaces the faulty parts, and refills your system to the manufacturer’s specifications.
