The Ultimate Guide To Installing A Ductless Air Conditioner In San Diego

Ductless air conditioners stand out for their high efficiency, quiet operation, and versatility. Because installing a fashionable ceiling or wall mount indoor unit does not limit the design of an AC system due to the presence of ductwork, conditioned air can be delivered to nearly any location.

Ductless air conditioners are frequently less expensive than traditional air conditioners since they do not require air distribution supplies or personnel during installation. After comparing maintenance needs and operational costs, many homeowners discover that their reservations about ductless air conditioner prices were unwarranted.

A professional and qualified heating and cooling dealer should install a ductless heating and cooling system, just like any other HVAC product. Homeowners and handypersons lack the knowledge and skills necessary to complete the electrical connections and charge the system with refrigerants. A faulty installation can void the warranty and damage the equipment permanently. Best air conditioning installation Los Angeles is factory-educated and has the skills and experience to install ductless air conditioning professionally, affordably, and without the slightest disturbance to the customer’s lifestyle.

Schedule an In-Home Consultation with a Local Installer

Even though ductless air conditioners are quite popular in many parts of the world, consumers in the United States may be unfamiliar with the technology. Any queries you may have about the ductless AC installation procedure can be answered by an Electric contractor in your area. Consultants can help uncover low-cost solutions to improve the building’s overall efficiency and evaluate the appropriate system size and placement alternatives for the equipment.

System Selection

Because DIY systems are rarely sold in brick-and-mortar locations, you may have little choice but to shop online. There are a plethora of internet vendors to choose from. The BTUs (British Thermal Units) describe the system’s size (British thermal units). The greater the number, the more cooling capacity there is. Calculate the room’s heat loss to find a suitable size ductless air conditioner. These calculations can be made easier on several websites.

Don’t estimate; an undersized system won’t keep up, and an enormous system will cycle on and off too often, reducing the condenser’s service life.

Supplying Electricity

Installing is essentially simple DIY things, as you’ll see in the stages below: measuring, drilling holes, driving screws, and so on. Getting power to the system is usually the most challenging part. You might be able to use a neighboring underloaded 20-amp circuit to control a remote system. More than likely, a new circuit devoted to the ductless air conditioner will need to be installed. Depending on how simple it is to extend the cable from the main panel to the unit, this can be a minor or significant effort.

It would help if you routed the cable from the basement up through the garage wall, up the attic, down and out the outside wall, and into a disconnect box by making three small holes in the drywall and later fixing them. (When repairing the device, the disconnect makes it secure and straightforward to switch off the electricity.) The condenser then receives power from the disconnect. The evaporator is powered by a cable connected to the line set.

Additional Sources

A flat surface is required for the condenser to rest. A concrete pad might be poured, but a plastic condenser pad is quick and straightforward to install. The line set’s cloth sleeve is unattractive and difficult to clean. Plastic line set cover kits are the solution.

Place the Outside Unit in Place

The outdoor condensing unit is simple to set up. A concrete pad should be poured on a level base, at least one foot away from an exterior wall. Concrete can alternatively be substituted with polyethylene or reinforced rubber pads. The vents should not be covered by foliage or other barriers, and the unit connectors should face the house.

Refrigerant lines should be running

Copper refrigerant lines are insulated with closed-cell rubber foam, and copper refrigerant lines are copper. A conduit that runs alongside the condensate drain and power wire is frequently used to shield them. The defrost wire should be run from the condensing unit to the indoor installation site, alongside the refrigerant lines and electrical cables.

Place the Indoor Unit

Depending on the type of fan coil selected, the indoor unit will be mounted high on an inside wall or in the ceiling. A 3-inch hole must be drilled precisely behind the device in an outside wall. The electrical connections are completed, and couplings connect the inside and outdoor units.

Finally, the system is charged with refrigerant and tested to meet the manufacturer’s requirements.

When purchasing and installing a ductless air conditioner, there are a few things to consider

The following variables should be considered before you make your purchase and begin the installation process:

  1. Air Conditioner Size (Ductless)

You’ll need to hire an expert to determine what size ductless air conditioner you’ll require. Homeowners frequently make the error of undersizing or oversizing a ductless air conditioner, resulting in inadequate cooling and higher utility expenses. For the near future, an adequately sized air conditioner will suffice.

  1. Ductless Air Conditioning Types

Before selecting a ductless Air Conditioner, you should think about the area and needs. Single-zone and multi-zone ductless air conditioners, as well as wall-mounted, floor-mounted, and ceiling cassette kinds, are the most popular ductless Air Conditioner options. Before making a final decision, you must first determine the size of the area and your heating and cooling requirements.

  1. Choosing the Right Location

For easy installation, a split system air conditioner should be mounted on an outside wall, preferably near the center of the room, to ensure even cooling. Above the indoor unit, leave at least 2 inches of vacant space.

For optimal ventilation, outdoor units should be surrounded by many open areas. Select a shady location that is easy to maintain. To avoid the compressor fighting gravity while the refrigerant is circulating, it’s advisable to situate them somewhat higher than the interior unit.

  1. Efficient energy usage

The efficiency of an air conditioner is measured by the EER and SEER ratings. The greater the rating, the better it is in general. Upgrading from a SEER 9 to a SEER 13 rating, for example, can save up to 30% on overall energy use.

Ductless Air Conditioner Maintenance Tips

Ductless air conditioners are simple to install, energy-efficient, and silent. Air conditioners and heat pumps are both accessible options. Heat pumps have the benefit of providing both heating and cooling in one device. Taking care of your ductless air conditioner, regardless of the model you have in your home or office, will extend its life, reduce the need for repairs, and keep your energy bills low. Here are three suggestions for keeping your equipment in good working order:

Filter Clean-up

The first line of defense in maintaining energy efficiency and performance is to keep the filter clean, like with any air conditioner. Filters catch airborne particles and keep them out of the unit’s mechanical parts. For proper heat exchange, air must freely flow across coils. The machine must work harder to discharge heat if particles gather on the coils. The compressor may eventually fail, resulting in reduced interior comfort and up to a 25% rise in energy expenses.

Housing and tubing that are free of contamination

Make sure there are no impediments in the housing of the outside unit. Heat exchange is hampered when leaves and dirt cling to coils. To remove dust, wipe the inside cabinet with a moist cloth.

Refrigerant, electrical, and condensate lines are routed via tubing between the inside and exterior cabinets. Moisture will build inside the unit if the condensate tube becomes blocked, causing damage. Check to see if the line is still supplying water.

Seasonal Maintenance by Professionals

To keep warranties valid, most manufacturers need seasonal maintenance. The housing, coils, fans, filters, and refrigerant will all be examined, cleaned, and calibrated by a competent HVAC specialist. To keep your HVAC equipment in tip-top form, Melton Heating and Air Conditioning offer annual maintenance contracts.


Knowing how simple it is to install a ductless Air Conditioner, you can rest assured that your next ductless Air Conditioner installation will go off without a hitch. You should be fine if you prioritize your safety. Your air conditioning should be both affordable and comfy once you install your ductless air conditioner and make it smart.
