Install AC


Install AC

Install AC requests in South & Central Florida peak during the hot summer months and escalate once units reach eight years or older. The most common central air conditioning brands including Rheem, Trane, Goodman, American Standard, York, Ameristar and Carrier, operate well for years if properly maintained with HVAC service plans but will eventually need to be replaced once they begin to show wear and tear including leaking refrigerant, freezing up and blowing warm air.  HVAC contractors like Air Pros will help a residential or commercial customers research, finance, install and maintain a new split air conditioning unit – the most common Install AC job performed in Florida.

Researching A New Central AC Install

The final AC installation configuration will rest on several factors but here are some key considerations which impact the final choice. Air Pros can help homeowners decide on the best course of action after a consult or home energy assessment.

Evaluating Central Air Conditioning Unit Size

A rough rule of thumb used by our service technicians is to allocate around 1 ton for each 500 square foot of space. Thus, if your home is around 1,500 square feet in size you would need a 1.5-ton unit. However, bear in mind this is just a rough guide. Other factors come into play, too, but it’s a good starting point.

Home Layout Considerations

When considering the above, also evaluate any unused space in hour home that may need priority cooling or heating.  For instance, if you have a large garage then consider subtracting this space from the final calculation.  An HVAC service technician can help identify other subtractions to help you nail down this metric.

Which Brands Are Best?

Over the last decade several brands have emerged as industry leaders including Trane, Rheem, Carrier and Goodman.   For instance, Air Pros has a strong AC install history for Rheem, Ameristar and Goodman units, which is partly due to pricing considerations, complexity, the personal preference of clients and also financing options.    In recent years, Trane has emerged as a leader in more premium AC system configurations that are typical of the ‘smart home’.

They offer powerful, programmable features for multi-stage cooling systems which allow a HVAC contractor to fine-tune a number of variables that affect air flow in a home.   With these features, however, also comes complexity and this can affect pricing.  Rheem, on the other hand, is focused on simpler configuration options which allow a homeowner to get a more affordable mix of options.  Goodman often offers extreme value and is becoming popular along with Ameristar. However, nearly all the brands mentioned on this brand have pros and cons, and the final decision rests on a dialogue between the homeowner, contractor and AC manufacturer.

SEER Rating

The Seasonal Energy Efficiency Ration (SEER) rating has become an established mechanism by which homeowners’ shop for a reliable central air conditioning system.  In a nutshell, the higher the SEER rating the more comfort you will get from each energy dollar.  The higher ratings also mean increased operational complexity inherent in each unit since they may involve 2-stage or variable-speed compressors which while increasing comfort also increase diagnostic complexity.

Unfortunately, there is no magical Seer number absolutely tied into each homeowner situation.  We typically suggest that homeowners should aim for around 16 Seer rating to keep things relatively simply but also extract long-term efficiencies.

Financing AC Install

Robust financing plans for a new central air conditioner purchases have grown considerably in Florida over the years. Air Pros, for instance, offers zero money down on new units and attractive financing rates for residential homeowners. Additional incentives may include $500 off new units based on specials running in your particular area including Coral Springs, Davie, Hollywood, Fort Lauderdale, Boca Raton, West Palm Beach, Ocala and The Villages

Installing AC in your Home

Once you have researched, identified, financing and purchased your new central air conditioning system, your HVAC contractor can begin the installation process which may take several hours and requires a scheduled appointment.

Same Day Install AC

In many cases, the AC install may take place same-day depending on the timing of the financing request and configuration of the homeowner residence.  Air Pros has recorded fast-turnaround times for homeowners in the past, but it will again depend on the unique situation of each implementation.


Air pros offers a 10-year warranty on all new central AC installs for all brands mentioned above including Rheem, Trane and Goodman.

Install AC Process

Remove existing air handler and condenser unit. Replace with like components.

The technician will go outside and connect the liquid dryer line from compressor to the air handler.

The technician ensures all four tie-downs are correctly in place for the condenser and secured to the concrete slab which houses the compressor.  It’s imperative the slab is leveled and the right size to accommodate the dimensions and weight of the AC compressor.

The technician then moves inside to weld refrigerant and copper lines from the inside to the outside. Failure to do this properly could result in internal smoking which has obvious health hazards.  This rarely happens but a good HVAC contractor will ensure it never reaches this point.

The tech then proceeds to weld copper lines with the liquid dryer line.

The tech will then run leakage test and run a vacuum pump to remove excess moisture.  Techs will test down to 500 microns on their pressure gauges to ensure no moisture has (or will) enter the “lungs” of the compressor.

The next step involves moving back inside to connect the plenum to air handler (i.e. air supply). The tech will then wire up the central AC unit including both low and high voltage.

The tech then moves back outside and to connect low voltage.  The pump will be checked, and he will close pump gauges to see if 500-micron level has been reached to ensure no leak or moisture.

The tech then connects the thermostat which will regulate the temperature levels within the home.

The next step involves opening the refrigerant line: Both the high and low side.  Once all connected, he will activate the relevant circuit breakers. This includes turn on breakers for air handlers, condensers (or break out).

One the above is complete, the tech will finally activate the thermostat and turn it to the default setting: Auto Cool.

After a few seconds to a minute, the air should come in which indicates the new Central AC install is complete.

One final step that the HVAC tech may perform includes checking the air temperature split between the air supply and the thermostat.  He does this using a laser thermostat gun which helps him establish no red flags, including an air temperature differential of more than 20 Degrees Fahrenheit between the supply and thermostat.  The laser can also calibrate the thermostat to the correct setting. If there is an issue some common causes could be a restriction or blockage in the coil which he will correct.

The tech will also take one final review of the running compressor outside, to make sure its correctly draining.

Red Flags To Consider

The condensing unit must always be 12 inches from the outside wall.

The concrete slab under the compressors should be leveled correctly.

We have seen instances where other companies have failed to put a primary flow switch in the drain line. This should be mandatory.  Additionally, we may recommend that a secondary float switch be attached to an auxiliary evaporator pan, which mitigates future instances when a unit may freeze, leading to water run-off and residue on floors.

If unit is located in garage in attic we highly recommend that an Ultraviolet light be installed on AC to combat excessive humidity and mold.

Your AC Install Is Complete!

Congratulations, your AC install is complete and signed off the HVAC contractor and you should be able to get 8-15 years of operational life out of your system if you leverage preventive maintenance plans described elsewhere on our site. This entire process including research, financing, installation and maintenance are managed by a reputable bonded and license HVAC contractor like Air Pros.
