Trying to find a new air conditioning unit? With more than 20 years of expertise and some of the finest customer reviews of any HVAC provider, Airmakers would like to help you choose the best air conditioning unit for your home. It’s important to give thought to factors such as dependability, warranties, unit integrity and budget. The climate and temperature extremes of the area also play a considerable role.

With a moderate climate, Mission Hills doesn’t get too hot or too cold, but residents there will still need a reliable HVAC system. The area has much older homes than many of the other San Diego communities. It’s heating and air requirements are much like Bankers Hill, Pill Hill (which San Diego old timers remember that name?) and Hillcrest. Let’s take a look at some units that could be ideal for your home if you live in any of these old San Diego communities.



Central Air Conditioning

This is a way of cooling an indoor space where a centralized unit cools down and dehumidifies air before circulating it through the structure. It usually incorporates a primary unit, which is usually situated outside of the building because noise is generated during the refrigeration cycles that cool the air and extract the humidity. A large ventilator inside the system pushes air through ductwork within the structure which will evenly cool the entire building.The area, or household, is often fitted with return air ducts that push air throughout filters, removing toxins and improving indoor air quality. The air conditioning unit also vents to the outdoors, eradicating surplus heat and moisture.


  • It will cool your home evenly and quickly and will usually be controlled to keep a uniform and ideal climate, keeping your home comfortable, even while outside conditions vary.
  • Since the main unit is located outside the house, the indoor noise level is much less than most other air conditioning units.
  • As a result of its air filtration system, air flow in the home is considerably cleaner and healthier for your loved ones.
  • A centralized air product can incorporate heating as well, making the unit an all-in-one central heater and air conditioner.


  • The disadvantage of central air conditioning is it demands the aid of a qualified HVAC contractor to install. You can’t install it on your own.
  • As a result, it is the most expensive air conditioning unit for the home and installation will probably run a few thousand dollars. Call Airmakers Heating and Air Condtioning at 858.530.1822 for an estimate.

Window Air Conditioners

These are single units that fit into windows or holes through a wall in your house; they are self-contained units that bring air from the outside and push it into a individual room.


  • Window Air units are generally much cheaper than central air. Quality units may range from $100 to $200, but usually only cool a single room.
  • Once installed, window brands are quite easy to use. More recent models usually come with remote control.


  • In a home with many rooms, multiple units will get expensive. You could install window air conditioners yourself, but it may require an HVAC contractor depending on the model as well as its location.
  • Window air conditioners really don’t consist of heating options. For heat, you’ll have to look at space heaters or furnaces.

Ductless Mini-Split Air Conditioning Units

Going ductless can be an very good alternative for anyone who cannot afford a new central air conditioning system. Like central air, the system is “split” into an outdoor compressor/condenser and an indoor handling unit. A conduit links the two systems. These units cool just one room at a time, just like window air conditioners and in most cases come with a handy remote control to regulate settings.


  • The advantage of ductless is they don’t 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 takes a 3 inch hole to connect the inside unit to the outside compressor, which can be up to fifty feet away. These solutions are great for retrofitting projects and room add ons.
  • Ductless mini-split systems are less expensive than central air units, yet more expensive than window air conditioners. A good mini-split unit will usually run between $600 and up to $3000, depending on the space being cooled.


  • Mini-split units can only cool one room so if you have lots of rooms, installation and operation are going to get expensive.
  • Dealing with temperatures in each room that has a unit could be time consuming and difficult.
  • Just like window versions, ductless systems do not incorporate a heating element.

Heat Pumps

Notwithstanding their name, heat pumps are a kind of central cooling system that also incorporates heat. This is the all-in-one system named above. It’s a automatic cooling system that can be reversed to offer hot as well as cold air to a controlled living space. The main housing of the split system is located outdoors and makes use of ductwork to deliver cold or hot air through your home. These models are our best sellers because of their capability to change temperatures and energy conservation.


  • Heat pumps have similar advantages of other central cooling units.
  • They can be very efficient when it comes to energy use while offering powerful output for either hot or cold air.
  • The latest designs have become effective at regulating individual room temperature ranges.


  • Heat pumps may run a few thousand dollars for full set up and installation, depending on the size of your home.
  • Heat pumps are required to be put in by a competent HVAC contractor. Call Airmakers Heating and Air Conditioning for a quote at 858.530.1822.

Portable Air Conditioners

Portables are your cheapest option for cooling, even though they’re best used for small areas and as short-term solutions. Not a practical alternative for cooling large areas, portable air conditioners are not a bad choice for small working areas, garages on warm days or to supply temporary relief from the heat in small room.


  • Although they are very small when compared to other air conditioning units, portable units can generate plenty of cool air.
  • Portables tend to be small, convenient and can be put in virtually any room with a power outlet.
  • Systems like this can be obtained at many hardware and big box outlets and normally go between $100 and $300.


  • They frequently use up a large amount of energy and can increase your energy bill.
  • They are not a practical option if you must cool an entire home.
