What is Central Air Conditioning?

During the summer months, sometimes all you wish for is the sweet relief of the cold air.  Central air conditioners offer that warm air relief with a quick adjustment to the thermostat.  To help you get the most out of your central air conditioning unit, count on the HVAC experts at Bill Howe to get you there.

What is Central Air Conditioning?

To better understand how to get the most out of your central air conditioning unit, considering what central air conditioning is exactly is key.  Central air conditioners work in four simple steps:

Step 1:

Warm air is drawn from inside your home and blown across a set of indoor coils.  The heat is then absorbed by the refrigerant and causes it to evaporate into its gas form.

Step 2:

The refrigerant gas then moves through a compressor and is pressurized.  The gas heats up and moves to the coil located in the outdoor portion of the unit.

Step 3:

A fan located within the outdoor unit moves air from the outside across condenser coils.  Because the outdoor air is cooler than the hot, compressed gas refrigerant, heat is moved from the refrigerant to the outdoors.  With the refrigerant now cooled, it condenses back to its liquid form and moves to the expansion valve of the indoor unit.

Step 4:

The expansion valve decreases the pressure of the warm, liquid refrigerant and cools it significantly. With the refrigerant back in its cool, liquid state and can start the cooling process over again.

Central air conditioners help to circulate cool air through a series of supply and return ducts by removing hot air from inside the house and blowing cool air back into your home. Discomfort can also be created by humidity which air conditioners help to reduce.  

Bill Howe offers two different types of central air conditioners – split systems and package systems.  With a variety of systems offered from various manufacturers, finding your perfect fit will be a breeze.  

A split air conditioning system has both an outdoor and indoor unit. The indoor portion of the unit is quiet, sleek and mounted directly into your home.  A benefit of having the unit mounted directly into your house is that it can help cool areas that may be difficult to reach using a package system. Multiple indoor units connected to one, central outdoor unit can also be installed giving you the ability to cool multiple rooms or areas easily.  Installation of a split air system is easier because it does not require the ductwork that is required from other types of central air conditioning systems. While a split air conditioning system is more expensive than a window-mounted unit and does require professional installation, the longevity and energy-efficiency of the AC unit helps to offset the cost.

Package systems are known for their small footprint and can be placed on the roof or side of your property.  The packaged air conditioner houses the compressor, coils and air handles in a single, boxed cabinet. While this system is typically used for commercial properties, it can be used for residential properties as well. Package systems also offer the benefit of both heating and cooling your property.  Since all the components of the packaged air conditioner are housed within one unit, maintenance is a breeze. With this system, it eliminates the need for a separate furnace which in turn saves you space.  Installation is more difficult than other options, but is still energy efficient.  

Best Way to Circulate Air

Once your new central air conditioner is installed, there are a few methods you can use to best circulate the cool air throughout your home.  

AC & Fans = A Great Cooling Combo:

When using fans and AC in tandem with one another, cranking down the air conditioner won’t be necessary.  When using fans and setting the thermostat to mirror the temperature outside not only save you money, but can help create a comfortable, indoor temperature.  When the air conditioner runs, the cold air it produces settles closer to the floor and does not circulate that well. Fans help eliminate this problem. Strategically-placed fans help to move the settled, cold air and push it towards hot areas.  With strong enough fans, air is moved throughout your home to help lower the temperature throughout and lower your power bills.

Box or oscillating fans are best at creating a cool air flow within your home. Placing your box or oscillating fans near the vents will help push air further out.  Fans also will help air circulate throughout your home to move cool air to the hotter areas.

Utilize Exhaust Fans:

Exhaust fans used in your bathrooms, kitchens or attics can help move hot air out of your house.  By removing the hot air that settles near the ceiling of your home, better air circulation is created.  Once the hot air is removed, there will be a noticeable difference in air quality and temperature.


While dehumidifiers will not help circulate air or lower the temperature within your home, it will help create a more comfortable temperature.  Higher humidity can certainly create discomfort within your home, by decreasing the humidity, a noticeable difference can be felt and make your home feel cooler, without actually cooling down your house.

Very Satisfied. Michael is always on time, Michael has been doing all of the plumbing related to our remodel. He always does exactly what he commits to do within the estimated cost. He keeps me informed if any wrinkles pop up, and his plumbing skills are excellent as we have had no problems or issues arise after he has left. Very professional! Highly recommend.

What Rick M says about us

We had other companies come out for estimates on what was considered a major job with jackhammers and replacing cast iron pipes under the house… having been stung before, we wanted another estimate just to make sure we were making an informed decision. The prior estimates went up to $21,000!
Bill Howe sent us an amazing veteran plumber, Dashawn and his co- worker Anthony. Dashawn did a thorough check of the problem, explained what he thought was needed … he did a final check and we were able to see for ourselves what was the problem. He recommended a complete cleaning to de-scale the pipes, and not the major work we dreaded. Thanks to his solid analysis and patience in making sure we saw what he saw, the issue was resolved completely, and saved us thousands of unnecessary work. None of the other estimates included the cleaning; only the major repairs. Thanks to Dashawn’s knowledge, professionalism and honesty, we’re Bill Howe customers.

What Carolyn Housman says about us

This was our second excellent experience with Bill Howe. We had a blocked kitchen sink drain 8/5. I was able to get a same day appointment which is AMAZING. Person on phone was very courteous and set me up right away. Tony arrived at the house (called me 30 minutes out so I was able to be ready). He diagnosed the issue (blocked drain, not the garbage compactor) and was able to snake it and ran the water for 10 minutes to be sure the drains were clear. He cleaned up everything and you would not have known he was even there. Thank-you Tony and Bill Howe, you always know how.

Cory was our technician on this job. We had a time sensitive repair issue and Bill Howe understood and assisted with getting the job done quickly.
Cory was on time to start the job and finished it quickly. Upon his leaving our home he’s was courteous, very knowledgeable, explaining what the problem was and how he fixed it. Very good communication and this is the way it’s has always been when we use Bill Howe plumbing.
Great company to work with.
Thanks Cory.

What Bridgett says about us

I am extremely happy with the service we received from Bill Howe Plumbing. We were given an incorrect diagnosis of our main sewer line from another vendor, but Bill Howe’s servicemen came out for a second opinion, correctly diagnosed our problem and resolved our back up issues. We will continue to use Bill Howe for all our future plumbing needs!

Thank you Bill Howe Plumbing.
