It’s always a good step to read about a unit before you buy it. A new air conditioning unit is no exception. It’s good to research the various kinds of models just like you’re doing now, but to really choose the ideal unit for your home, a home heating and air conditioning contractor will have to come out and survey the property to determine what kind of unit is appropriate for you and your family. There will be many considerations, including where you live.If your community is El Cajon, then you know all to well how hot it can get during the summer.

Not only is it an inland community, but the El Cajon Valley can trap hot air that sits, causing temperatures to rise so high that residents feel like their baking in an oven. Having a good air conditioning system functioning evenly throughout your home is essential. The first step is to call a heating and air contractor to come out and take a look at your home. When the HVAC contractor has finished the assessment of your home, they will probably have a good recommendation for you. But let’s not rush directly into all that just yet. Let’s have a look at examples of the various units.



Central Air Conditioning

Central Air Conditioning is a way of cooling an interior location in which a centralized unit cools down and dehumidifies air flow before distributing it through the building. It usually includes a main unit, which is situated outside of the building since 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 within the structure that can consistently cool an entire building.The building, or household, is normally installed with return air ducts that pull air through filters, removing pollutants and improving indoor air quality. The air conditioning unit also vents to the outdoors, removing excessive heat and moisture.


  • It will cool a home consistently and quickly and can generally be regulated to keep a uniform and ideal climate, keeping the entire structure comfortable, even while exterior air temperatures fluctuate.
  • Given that the primary unit is situated outdoors, the inside noise level is much less than other air conditioning units.
  • As a result of its air filtration system, air in the home is considerably cleaner and healthier for your family members.
  • A central air device can incorporate heat as well, making the system an all-in-one heater and air conditioner.


  • The disadvantage of central air conditioning could be that it requires the aid of a capable HVAC contractor to set up. You cannot install this system yourself.
  • As a result, it is the most expensive air conditioning unit for your household and installation will likely run a few thousand dollars. Call Airmakers Heating and Air Condtioning at 858.530.1822 for an estimate.

Window Air Conditioners

As single units that fit within windows or holes through a wall in your house; they are self-contained devices that take air externally and force it into a particular room.


  • These models can be much less expensive than central air. Good units could cost from $100 to $200, but they generally can only cool an individual room.
  • After installation, window brands are easy to use. More recent styles almost always include a remote control.


  • If you have a big house with lots of rooms, multiple units will get expensive. It is possible to fit window air conditioners yourself, but may require an HVAC professional depending on the system and its location.
  • Window air conditioners really don’t incorporate heating solutions. For heat, you’ll have to look at space heaters or furnaces.

Ductless Mini-Split Air Conditioning Units

Going ductless could be an terrific choice for anybody who simply can’t afford a new central air conditioning system. Similar to central air, the system is “split” into an outdoor compressor and an indoor handling unit. A conduit joins the two systems. These types of systems cool a single room, just like window air conditioners and generally come with a handy remote control to adjust settings.


  • The benefit of ductless is they don’t require the extensive ductwork and set up of a central cooling system, nor will they require a window or large hole like window air conditioners. A ductless mini-split system ordinarily only needs a 3 inch opening to connect the inside unit to the outside compressor, which can be as much as 50 feet away. These systems are great for retrofitting projects and room additions.
  • Ductless mini-split systems are cheaper than central air units, but more expensive than window air conditioners. A pretty good mini-split unit will usually run between $600 and as much as $3000, depending on the space being cooled.


  • Mini-split units can only cool just one room so if you have lots of rooms, installation and operation are going to get costly.
  • Regulating temperature control in every room can be time consuming and difficult.
  • Like Window air brands, ductless systems do not incorporate heat.

Heat Pumps

Despite their name, heat pumps are a form of central air unit that also integrates heat. This is the all-in-one unit mentioned previously. It is a technical refrigeration system that can be reversed to offer hot as well as cold air to a regulated space. The main housing of the split system is located outside and employs ductwork to pass on cold or hot air around your home. These models are our biggest sellers because of their ability to regulate temperature ranges and energy usage.


  • Heat pumps supply similar features of other central cooling units.
  • They could be very efficient in terms of energy use while delivering powerful output for either hot or cold air flow.
  • Newer designs tend to be efficient at regulating individual room temperatures.


  • Heat pumps will run a few thousand dollars for parts and installation, but it depends on the size of your home.
  • They have to be installed by a competent HVAC contractor. Call Airmakers Heating and Air Conditioning for a quote at 858.530.1822.

Portable Air Conditioners

Portable AC units will be your least costly choice for cooling, even 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 option for small living spaces, garages on hot days or to give temporary relief from the heat in small room.


  • Although they are very small in comparison to other air conditioning units, these systems can output a good deal of cool air.
  • They can be small, mobile and can be situated in almost any room that has a power outlet.
  • Systems like this can be obtained at most hardware and big box outlets and frequently go between $100 and $300.


  • They typically use up a lot of electricity and will add significantly to your energy bill.
  • They are not an efficient option if you need to cool the entire home.
