Since we’ve put in so many air conditioning units in Coronado homes over the years, we thought we’d write an article on some of the various kinds of units you can put in your house if you live there. There’s a good chance that any of the units below may work for your needs.



Central Air Conditioning

For larger areas, this is a method of cooling an interior location in which a centralized unit cools and dehumidifies air before circulating it through the structure. It usually includes a primary unit, which is usually situated outside of the building because noise is created during the refrigeration cycles that cool the air and removes the humidity. A large motorized inflator inside the system pushes air through ducts in the structure which will equally cool an entire building.

The building, or residence, is generally installed with return air ducts that draw air throughout filters, removing pollutants and restoring indoor air quality. The air conditioning unit also vents to the outdoors, reducing surplus heat and moisture.


  • It can cool a home evenly and quickly and will usually be regulated to maintain a uniform and desired temperature, keeping the entire structure comfortable, even while outside temperatures rise.
  • Since the primary unit is located outside the house, the inside noise level is significantly lower than other air conditioning units.
  • Due to its air filtration system, air flow in the home is a lot cleaner and healthier for your family members.
  • A centralized air device can incorporate heat as well, making your unit an all-in-one heater and A/C unit.


  • The downside of central air conditioning could be that it requires the aid of an experienced HVAC contractor to set up. You cannot fit it by yourself.
  • As a result, it is the most expensive air conditioning unit for the home and installation likely will run a few thousand dollars. Call Airmakers Heating and Air at 858.530.1822 for an quote.

Window Air Conditioners

Window Air Conditioners are single units that fit into windows or holes through a wall in your home; they are self-contained systems which take air externally and drive it into a particular room.


  • These kind of units tend to be much cheaper than central air. Good units could cost from $100 to $200, but usually only cool an individual room.
  • Once installed, window brands are quite easy to use. Newer styles almost always include a remote control.


  • If you have a lot of rooms, multiple units could get costly. It is possible to mount window air conditioners yourself, but be prepared for help because it mght require an HVAC contractor depending on the model and its position.
  • Window air conditioners do not feature heating options. For heat, you’ll have to look at space heaters or furnaces.

Ductless Mini-Split Air Conditioning Units

Going ductless is an good alternative for someone who simply can’t afford a new central air system. Like central air, the system is “split” into an outside compressor/condenser and an interior handling unit. A conduit joins the two systems. These types of units cool a single room, simillar to window air conditioners and usually come with a handheld remote control to alter settings.


  • The benefit of ductless is that they do not require the substantial ductwork and set up of a central cooling system, nor will they need a window opening or large hole like window air conditioners. A ductless mini-split system normally only requires a 3 inch opening to attach the interior unit to the outdoor compressor, which may be as much as 50 feet away. These kind of systems are ideal for retrofitting jobs and room additions.
  • Ductless mini-split systems are cheaper than central air units, yet more expensive than window air conditioners. A quality mini-split unit will normally run between $600 and up to $3000, depending on the area being cooled.


  • Mini-split units can only cool just one room so if you have many rooms, installation and operation can get expensive.
  • Managing temperatures in every room could be time consuming and difficult.
  • Just like window AC units, ductless systems don’t integrate heating options for the winter.

Heat Pumps

In spite of their name, heat pumps are a type of central air system that also offers heat. This is the all-in-one system mentioned above. It’s a automatic refrigeration system that can be reversed to offer hot as well as cold air to a controlled space. The principle housing of the split system is positioned outside and makes use of ductwork to dispense hot or cold air throughout your home. These units are our major sellers as a result of their ability to change temperatures and energy conservation.


  • Heat pumps offer similar advantages of other central cooling models.
  • They can be very efficient with regard to energy use while supplying powerful output for either hot or cold air.
  • Recent systems have gotten efficient at controlling individual room temperature ranges.


  • Heat pumps can run a few thousand dollars for full set up and installation, depending on the size of your home.
  • They must be fitted by a skilled HVAC contractor. Call Airmakers Heating and Air Conditioning for a quote at 858.530.1822.

Portable Air Conditioners

These will be your least expensive choice for home cooling, though they’re best used for small spaces and as short-term solutions. Not a practical choice for cooling sizeable areas, portable air conditioners are not a bad alternative for small additions, garages on warm days or to offer temporary relief from the heat in small room.


  • Given they are small when compared with other air conditioning units, portable units can produce a good deal of cool air.
  • These units can be small, convenient and can be positioned in any room with an outlet.
  • Systems like this can be purchased at many hardware and big box outlets and normally run between $100 and $300.


  • They generally use a great deal of electricity and will increase your energy bill.
  • They are not an efficient solution when you have to cool the entire home.
