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.

Maintenance Checklist

Maintain your equipment to prevent future problems and unwanted costs. Keep your cooling and heating system at peak performance by having a contractor do annual pre-season check-ups. Contractors get busy once summer and winter come, so it's best to check the cooling system in the spring and the heating system in the fall. To remember, you might plan the check-ups around the time changes in the spring and fall.

A typical maintenance check-up should include the following.

• Check thermostat settings to ensure the cooling and heating system keeps you comfortable when you are home and saves energy while you are away.
• Tighten all electrical connections and measure voltage and current on motors. Faulty electrical connections can cause unsafe operation of your system and reduce the life of major components.
• Lubricate all moving parts. Parts that lack lubrication cause friction in motors and increases the amount of electricity you use.
• Check and inspect the condensate drain in your central air conditioner, furnace and/or heat pump (when in cooling mode). A plugged drain can cause water damage in the house and affect indoor humidity levels.
• Check controls of the system to ensure proper and safe operation. Check the starting cycle of the equipment to assure the system starts, operates, and shuts off properly.

Cooling Specific

• Clean evaporator and condenser air conditioning coils. Dirty coils reduce the system's ability to cool your home and cause the system to run longer, increasing energy costs and reducing the life of the equipment.
• Check your central air conditioner's refrigerant level and adjust if necessary. Too much or too little refrigerant will make your system less efficient increasing energy costs and reducing the life of the equipment.
• Clean and adjust blower components to provide proper system airflow for greater comfort levels. Airflow problems can reduce your system's efficiency by up to 15 percent.

Heating Specific

• Check all gas (or oil) connections, gas pressure, burner combustion and heat exchanger. Improperly operating gas (or oil) connections are a fire hazard and can contribute to health problems. A dirty burner or cracked heat exchanger causes improper burner operation. Either can cause the equipment to operate less safely and efficiently.

Actions To Do Yourself

• Inspect, clean, or change air filters once a month in your central air conditioner, furnace, and/or heat pump. Your contractor can show you how to do this. A dirty filter can increase energy costs and damage your equipment, leading to early failure.

Air Handlers

Air handlers use smart technology to efficiently circulate the air, varying its speed based on your home's heating and cooling requirements while saving electricity by working only when needed. This means your unit turns on and off (as you may have heard on a quiet evening) and works only when needed. It knows when it is needed because of specialized sensors inside the machine.

Certain brands are more popular, or more highly recommended than others partly because of their life span or cost, but predominantly because of those sensors functioning optimally to keep your home the proper temperature and doing so as efficiently as possible.

New Home, Old AC

Congratulations on purchasing your new home! 

Let's talk about the elephant in the AC cupboard.

Sometimes a great house needs just one thing to make it perfect. In South Florida, if that thing is an AC unit, it can turn into feeling like a big thing quickly. It could be that your home inspector said

• that there are a couple of years left
• that it needs replacing immediately
• that the load test shows it is too small for the property
• that it is inefficient
• that the ductwork needs replacing

All of these are indicators of needing a new AC unit. Here's the good news:

A new AC will lower your monthly energy bill!

That's right. An older, inefficient unit will cost you more over 3 years than a new unit. It will essentially pay for itself. Plus, there are rebates you can request for replacing your AC unit from FPL and the government. Look at that, you're getting money back already!

Turn that frown upside down and trust us to do a great job replacing your AC unit and ductwork for clean, cold, fresh air!

Contact GMC AC Services at 954-973-5980 for an estimate today.

Home Maintenance

Save a little money later by doing a few small things now to maintain your air conditioning unit.

Change your filters. We will remind you on Facebook at the beginning of every month.

Clean the drain line. Pour a little bit of bleach down the drain line pipe every six months — that will reduce the amount of algae build up in the drain line and reduce the chance of the drain line filling up with water.

Clear the bushes. Check for efficient air-flow around your unit. Make sure your air conditioner has plenty of “breathing” room. Avoid enclosing or covering it; keep leaves, plants and other vegetation at least 18″ away.

Schedule maintenance. Your home's units should be tuned up at least once per year.

AC Q&A

Here is a most informative Q&A from the Palm Beach Post:

What are SEERS?

SEER stands for “seasonal energy efficiency ratio.” The SEER rating is the BTU of cooling output during its normal annual usage divided by the total electric energy input in watt hours during the same time frame.

SEERS range from 13 (lowest) and 21 (highest). The higher the SEER rating, the more energy efficient the system is.

I bought my first house and am now responsible for air-conditioning care. What is the difference between all these stage systems and compressors, and what will help me with my electric bills?
A two-stage system is designed to further reduce electrical consumption. Most people purchase single-stage air-conditioning units because they are less expensive than a two- stage, but aside from the price factor, most people are not properly educated on the benefits of having a two-stage system.

A single stage starts up at 100% capacity while two stages start up at 50-66% capacity, and 15 seconds later switch to 100% capacity. A two-stage system draws less amperage on start up, which helps you save money on the electrical bill. Two-stage systems also automatically switch back to 50-66% capacity when indoor and outdoor temperatures permit, therefore lowering electric use.

Other added benefits of the two-stage system include on-demand dehumidification features. If your home reaches the desired temperature set point but the humidity level is very high in the home, the system will go into de-humidification mode that brings the humidity levels down to the requested level. This allows you to have your home set at a higher temperature set point with less humidity in the air, so you are more comfortable in your home at an even higher temperature set point because there is less humidity in the air.

It’s 98 degrees outside and my AC is not blowing. What do I do?

Check the breakers, and if it is not related to an electrical short, call for service. You can check to see if you have a dirty filter, as this may cause the unit to freeze up.

How do I care for the filter?

Filters should be changed or cleaned once per month. You can clean them by vacuuming it off and washing it with water (if it’s a washable filter). Let it dry completely before placing it back in.

Use a good quality filter like an electrostatic washable, which we sell and can have custom made to fit in the AC unit. If you prefer to change the filter every month, invest in a sponge pad smart filter that has a custom-made aluminum frame and a rubber seal gasket that goes along with the top of the filter.

With filters removed, check the coils by shining a flashlight. If they appear to have microbial growth on the coils or appear to be clogged in any way by dog hair or dirt impacts, have a specialist come in for a coil cleaning.

The fan blower inside the AC should also be removed and cleaned once every two to three years.

How do I care for my AC’s drain line?

Pour a little bit of bleach down the drain line pipe every six months — that will reduce the amount of algae build up in the drain line and reduce the chance of the drain line filling up with water.

How often should I have my AC tuned up?

It is recommended that you check your unit every six months.

SEERs?

What are SEERS?

SEER stands for Seasonal Energy Efficiency Ratio. The SEER rating is the BTU of cooling output during its normal annual usage divided by the total electric energy input in watt hours during the same time frame.

SEERS range from 13 (lowest) and 21 (highest). The higher the SEER rating, the more energy efficient the system is.

Florida's Winter

We in South Florida don't have to winterize our homes and cover and protect our exterior air conditioner units. However, as the weather is a little bit cooler, and before it becomes necessary to turn from cool to heat, it would be a good idea to prepare your AC unit.

Whether you use your AC every day or almost never, simply switch your AC to heat and let it blow a few moments. This will dust off the heating coils. If you notice a bit of a "burning dust" smell, that's okay. Anything greater than that, including smoke, will need an inspection.

It is better to call us out now, before you need us on a chilly night or with a house full of guests.

Importance of Clean Air Filters

Breathing fresh, clean air is important to our health. But if we don’t make it a habit to change the filters in our home air systems, the equipment can fail, making matters much worse. Maintaining a good filter maintenance schedule protects the air we breathe and the heating and cooling equipment in our homes.

Airflow goes hand-in-hand with the efficiency of your HVAC system, and furnace filters assist with this. Dirty filters restrict the airflow, which results in higher energy and even HVAC repair costs.

With your typical off-the-shelf throwaway HVAC filter, it collects particles in the filtering medium. After it collects a certain amount of particles and is full, you simply remove it, throw it away, and replace it with another.

It is important to remember the more efficient the filter or the dirtier the air, the faster the filter is going to fill up and need to be replaced. It is recommended that HVAC air filters be checked at least every 30 days for an excessive load up of particles. If the filter looks overloaded on day 30, then you will have to change the amount of time you check the filter. On the other hand, if the filter looks particularly clean, you can relax the schedule of checking it.

Aside from keeping the air in your home clean, if your air system is working with a dirty air filter, it will slow down its efficiency as it slows down to do the same job. As a result, you’ll be paying more money to keep your home warm or cool.

And last but not least, an air filter helps keep the interior of your equipment clean. If a dirty air filter I kept in use, it could damage your equipment, or even cause it to break down entirely, which won’t do you any good.

Prevent overpaying for heating and cooling your home, or repairing the equipment by maintaining a schedule to replace your air filters.

Preventative Maintenance

From the experts at Trane, one of the leading manufacturers or AC units:

You wouldn’t drive your car 100,000 miles without changing the oil. The same logic holds true for your home comfort system. Regular preventative maintenance is the best way to ensure trouble-free operation and peak performance. Pre-season maintenance is also important. It can help to avoid a system failure in severe hot or cold weather when you need it most, and it can also keep your energy bill from getting out of control.

WHEN SHOULD I DO MAINTENANCE?

The old adage is true: an ounce of prevention is worth a pound of cure. Below you’ll find our Preventative Maintenance Checklist, which is our proven method to keep your system in the pink and your home in constant comfort.

• For a system that heats and cools: perform maintenance in the spring and fall.
• For cooling only: perform maintenance at least once a year, before the cooling season.
• For heating only: perform maintenance at least once a year, before the heating season.

PREVENTATIVE MAINTENANCE CHECKLIST

Many dealers provide priority service for their customers who have an annual maintenance or service agreement. Bi-annual preventative maintenance will ensure that your system runs as efficiently as possible. Your local dealer will perform the following tasks, depending on the unit:

OUTDOOR UNITS

• Inspect unit for proper refrigerant level and adjust if necessary
