Since we spend much of their time installing air conditioning units in Rancho Penasquitos, we decided to create an article regarding several of the different types of units you can put in your home if you live there. We know from experience that any of the systems below may work for your home.



Central Air Conditioning

Central Air Conditioning is a way of cooling an indoor space where a central system cools and dehumidifies air flow before circulating it throughout the structure. It usually includes a principal unit, which is usually located outside of the building since noise is created during the refrigeration cycles that cool the air and removes the moisture. A large blower within the unit pushes air through ductwork in the structure that can consistently cool an entire building.The area, or house, is normally fitted with return air ducts that push air throughout filters, removing pollutants and improving indoor air quality. The air conditioning unit also vents to the outdoors, eradicating excess heat and moisture.


  • It has the ability to cool a house evenly and quickly and can generally be regulated to sustain a uniform and ideal environment, keeping everything comfortable, even while exterior air temperatures fluctuate.
  • Given that the main unit is located outdoors, the indoor noise level is significantly less than many other air conditioning units.
  • Due to its air filtration system, air flow throughout the home is a lot cleaner and healthier for your family members.
  • A centralized air product can combine heating as well, making the system an all-in-one heater and A/C unit.


  • The drawback to central air conditioning could be that it demands the assistance of an experienced HVAC contractor to set up. You can’t set up this system by yourself.
  • Hence, it is the most expensive air conditioning unit for your house and installation will more than likely run a few thousand dollars. Call Airmakers at 858.530.1822 for an quote.

Window Air Conditioners

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


  • These models can be less expensive than central air conditioning. Good units can range from $100 to $200, but they usually only cool an individual room.
  • After installation, window units are easy to use. More recent styles usually include a handheld remote control.


  • In a home with many rooms, multiple units will get expensive. It is possible to mount window air conditioners yourself, but it may require an HVAC specialist depending on the system as well as placement.
  • Window air conditioning units do not consist of heating solutions. For heat, you’ll want to look at space heaters or furnaces.

Ductless Mini-Split Air Conditioning Units

Going ductless can be an terrific alternative for someone who cannot afford a new central air system. Like central air, the system is “split” into an exterior compressor/condenser and an interior handling unit. A conduit joins the two devices. These types of systems cool just one room at a time, simillar to window air conditioners and usually come with a handheld remote control to change settings.


  • The good thing about ductless is that they do not require the extensive ductwork and installation of a central cooling system, nor will they require a window opening or large hole like window air conditioners. A ductless mini-split system normally only takes a 3 inch opening to attach the interior unit to the outside compressor, which may be as much as 50 feet away. These kind of units are ideal for retrofitting jobs and room additions.
  • Ductless mini-split systems are less expensive than central air conditioning units, yet more expensive than window air conditioners. A quality mini-split unit will most likely run between $600 and as much as $3000, depending on the location being cooled.


  • Mini-split units can only cool just one room in your home so if you have a lot of rooms, installation and operation can get costly.
  • Dealing with temperatures in every room that has a unit will be frustrating and difficult.
  • Just like Window air versions, ductless systems don’t integrate heat.

Heat Pumps

Notwithstanding their name, heat pumps are a type of central air conditioning unit that also offers heat. This is the all-in-one unit mentioned previously. It is a technical cooling system that can be reversed to offer hot as well as cold air to a controlled space. The main housing of this split system is placed outdoors and uses ductwork to disperse cold or hot air through your home. These models are our greatest sellers because of their capacity to regulate temperatures and energy usage.


  • Heat pumps have the same advantages of other central cooling systems.
  • These systems can be quite efficient with regard to energy use while supplying powerful output for either hot or cold air.
  • The latest designs tend to be efficient at regulating individual room climate.


  • Heat pumps will run a few thousand dollars for complete installation, but it depends on the area you need regulated.
  • Heat pumps are required to be installed by a qualified HVAC contractor. Call Airmakers Heating and Air for an estimate at 858.530.1822.

Portable Air Conditioners

These are your least costly alternative for home cooling, though they are best used for small areas and as short-term solutions. Not a practical choice for cooling large areas, portable air conditioners are not a bad choice for small living spaces, garages on hot days or to supply temporary relief from the heat in small room.


  • Though small in comparison to other air conditioning units, portable units can generate a good deal of cool air.
  • They are small, lightweight and can be positioned in pretty much any room that has an outlet.
  • Systems like this are usually available at many hardware and big box stores and usually go between $100 and $300.


  • They normally use a large amount of power and may increase your energy bill.
  • They are not an efficient alternative if you must cool the entire house.
