While varying weather conditions are usually the most important factor when purchasing a brand new air conditioning unit for your home in San Carlos, there are more things to consider as well. Your greatest source for the information you need will be a knowledgeable HVAC contractor like Airmakers Heating and Air.

Airmakers has done a lot of heating and air installations and change-outs over the years in the San Carlos, Grantville, Del Cerro and Allied Gardens communities. We’ll most likely talk to you about a few of the kinds of systems that other area homeowners have installed in their homes. Take a look at some of the air conditioning units below:



Central Air Conditioning

This is a method of cooling an indoor space in which a central component cools and dehumidifies air before distributing it through the structure. It usually incorporates a main unit, which is normally located outside the building because noise is generated during the refrigeration cycles that cool the air and extract the moisture. A large motorized inflator within the system pushes air through ducts in the structure which will evenly cool the whole building.The structure, or house, is often installed with return air ducts that pull air through filters, removing contaminants and restoring indoor air quality. The air conditioning unit also vents to the exterior, eradicating surplus heat and moisture.


  • It has the ability to cool a house evenly and swiftly and can normally be controlled to keep a uniform and desired temperature, keeping things comfortable, even while outside air temperatures fluctuate.
  • Considering the fact that the primary unit is situated outside the house, the inside noise level is much lower than many other air conditioning units.
  • Because of its air filtration system, air throughout the home is a lot cleaner and healthier for your family.
  • A central air model can include heating as well, making your system an all-in-one heater and A/C unit.


  • The drawback to central air conditioning is it calls for the help of a capable HVAC specialist to set up. You can’t fit it on your own.
  • For that reason, it’s the most expensive air conditioning unit for your house and installation will probably run a few thousand dollars. Call Airmakers Heating and Air at 858.530.1822 for an estimate.

Window Air Conditioners

As single units that fit into windows or holes through a wall in your home; they are self-contained units which draw air externally and drive it into a individual room.


  • These kind of models tend to be much cheaper than central air conditioning. Effective units can range from $100 to $200, but they generally can only cool an individual room.
  • Once installed, window units are very easy to use. Current varieties usually include a remote control.


  • If you have a lot of rooms, multiple units will get expensive. You could install window air conditioners yourself, but be prepared for help because it mght require an HVAC technician depending on the model as well as location.
  • Window air conditioners really don’t integrate heating options. For heat, you’ll have to look at space heaters or furnaces.

Ductless Mini-Split Air Conditioning Units

Buying a ductless mini-split system is often an terrific option for someone who simply can’t afford a new central air conditioning system. Similar to central air, the system is “split” into an outdoor condenser and an indoor handling unit. A conduit links the two units. These kind of units cool only one room, just like window air conditioners and almost always include a handy remote control to alter settings.


  • The advantage of ductless is that they will not require the considerable ductwork and set up of a central cooling system, nor will they require a window opening or large hole like Window air systems. A ductless mini-split system generally only requires a 3 inch opening to connect the interior unit to the outdoor compressor, which can be up to fifty feet away. These systems are good for retrofitting projects and room additions.
  • Ductless mini-split systems are cheaper than central air conditioning units, though more expensive than window air conditioners. A pretty good mini-split unit will normally run between $600 and up to $3000, depending on the area being cooled.


  • Mini-split units are only able to cool just one room so if you have many rooms, installation and operation are going to get costly.
  • Managing temperature control in every room that has a unit could be time consuming and difficult.
  • Just like Window air units, ductless systems don’t integrate a heating element.

Heat Pumps

Notwithstanding their name, heat pumps are a form of central air system that also integrates heat. This is the all-in-one system stated earlier. It is a automatic refrigeration system that can be reversed to offer hot as well as cold air to a controlled area. The main housing of this split system is situated outside and employs ductwork to deliver hot or cold air around your home. These systems are our biggest sellers as a result of their capacity to control temperatures and energy conservation.


  • Heat pumps supply the same advantages of other central cooling units.
  • They can be extremely efficient with regard to energy use while supplying powerful output for either hot or cold air.
  • Current systems have become effective at controlling individual room temperatures.


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

Portable Air Conditioners

These are your cheapest alternative for cooling, though they are best used for small areas and as short-term remedies. Not a practical alternative for cooling large areas, portable air conditioners aren’t a bad choice for small working areas, garages on warm days or to provide temporary relief from the heat in small room.


  • Given they are small in comparison to other air conditioning units, portable units can output plenty of cool air.
  • Portables can be small, lightweight and can be put in any room that’s got a power outlet.
  • Systems like this are available at a lot of hardware and big box stores and typically go between $100 and $300.


  • They typically use up a great deal of electricity and can add significantly to your energy bill.
  • They are not a practical alternative if you must cool an entire house.
