Sizing an air conditioner correctly is the single most important decision made before AC installation ever begins. A unit that is too large will cool the air quickly but shut off before removing humidity, leaving your Lake Mary home damp and uncomfortable. A unit that is too small will run constantly, wear out prematurely, and never quite reach the temperature you set. At ABC Air Conditioning & Heating Specialist Inc.™, we treat sizing as a calculation rather than a guess, and that discipline shapes everything that follows.

Why Proper Installation Matters More Than the Equipment Itself

Two identical air conditioners installed by two different companies can deliver dramatically different results. The equipment specifications on the box tell only part of the story. Refrigerant charge, duct connections, airflow balance, electrical connections, and drainage all depend on the quality of the installation. When any of these elements is rushed or overlooked, the system underperforms regardless of how efficient the equipment is rated to be.

This is why we approach every AC installation in Lake Mary as a complete process rather than a swap of old for new. ABC Air Conditioning & Heating Specialist Inc.™ specializes in residential and light commercial sales and service, and our technicians are capable of repairing, replacing, or servicing every major make and model of HVAC equipment. That breadth of experience means we understand how each brand behaves once installed, and we set up your system to perform to its full published capacity instead of a fraction of it.

Our AC Installation Process Step by Step

A predictable process gives you confidence in what will happen and when. From the first visit to the final test, we keep you informed so there are no surprises on installation day. Our large fleet and dedicated staff allow us to move efficiently, and we regularly perform an installation within two business days of your decision to proceed.

  1. Load calculation: We measure your home’s square footage, insulation, window exposure, and layout to determine the correct cooling capacity in tons.
  2. Equipment recommendation: We match the calculated load to a unit with an appropriate SEER2 rating and features suited to your comfort priorities and budget.
  3. Removal of the old system: We disconnect, recover any refrigerant responsibly, and remove the existing equipment without disturbing your home.
  4. Installation and connection: We set the new indoor and outdoor units, connect refrigerant lines, electrical service, and condensate drainage, then seal all connections.
  5. Commissioning and testing: We verify refrigerant charge, measure airflow, confirm thermostat operation, and walk you through the completed system.

Each step is documented, and the technician on site answers your questions as the work moves along. We want you to understand not only what we installed but why each choice was made for your specific Lake Mary home.

Scenarios Where a New AC Installation Makes Sense

Homeowners come to us for installation in very different situations, and each one calls for a slightly different conversation. Recognizing which scenario fits your circumstances helps you decide whether repair or replacement is the smarter investment.

  • Aging systems past ten to fifteen years: Older units lose efficiency and often use refrigerants that are being phased out, making repairs increasingly expensive.
  • Repeated breakdowns: When repair calls become frequent, the accumulated cost frequently exceeds the value of a new, reliable installation.
  • New construction and additions: A room addition or a newly built home needs a system sized to the finished space, not an existing unit stretched beyond its capacity.
  • Rising utility bills: A modern high-efficiency unit can noticeably lower the cost of cooling a Lake Mary home through the long Florida summer.
  • Inconsistent comfort: Hot and cold spots often signal that the current equipment was never sized or installed correctly for the space.

If you are unsure which category applies to you, we are glad to evaluate your situation honestly. Sometimes a repair is the right answer, and we will tell you so. When replacement genuinely serves you better, we explain the reasoning clearly so you can make an informed decision.

Technical Specifications We Address During Installation

Comfort is the outcome, but the technical details are what produce it. During every AC installation we verify a set of measurable specifications, and we do not consider the job finished until each one falls within manufacturer tolerances. This attention to detail separates a system that merely runs from one that runs efficiently for years.

We confirm the refrigerant charge by measuring superheat and subcooling, because an over or undercharged system suffers reduced capacity and shortened compressor life. We measure static pressure in the ductwork to ensure the blower is not fighting excessive resistance, which wastes energy and strains components. We check the temperature differential between return and supply air to confirm the system removes heat at the expected rate. We also verify electrical draw against the unit’s rated amperage and inspect the condensate drain to prevent water damage and the humidity problems that come with backed-up drainage in a Florida climate.

SEER2 ratings, tonnage, blower speed settings, and thermostat compatibility all factor into how the finished system performs. Because our technicians work across every major brand, we know the specific commissioning requirements for the equipment we install rather than applying a single generic procedure to every job.

Why Lake Mary Homeowners Choose Us for Installation

Consumers have many options with respect to which Orlando A/C contractor they select, so we observe strict hiring practices to ensure the highest quality employees represent ABC both in the field and administratively so that our customers’ needs may be satisfied. The person who arrives at your door is trained, vetted, and accountable, and that consistency shows in the finished work.

Our customer service and quality of workmanship are unmatched in our industry, and our staffing makes that possible. We typically respond to a service request on the same day it was received, and we offer 24 hour emergency service with an experienced technician available 365 days per year. If a problem arises after your new system is installed, help is never far away. We proudly serve Lake Mary and the surrounding communities including Oviedo, Orlando, Cocoa, Sanford, and surrounding areas.

Protecting Your Investment After Installation

A new air conditioner is a significant investment, and regular maintenance protects that value over its full service life. Even a perfectly installed system collects dust, loses a small amount of refrigerant over time, and develops minor issues that are inexpensive to correct early but costly to ignore. Preventive care is the difference between a unit that lasts its full expected lifespan and one that fails years too soon.

We offer competitive preventive maintenance agreements wherein our technicians visit your home twice per year to evaluate, maintain, and clean your systems to ensure maximum operation efficiency. During these visits we inspect the same specifications we verify at installation, catching small deviations before they grow into failures. This ongoing relationship keeps your system operating near its original efficiency and preserves any manufacturer warranty terms that require documented maintenance.

From the first load calculation to the final commissioning test and every seasonal tune-up that follows, ABC Air Conditioning & Heating Specialist Inc.™ is committed to providing the ideal temperature in your Lake Mary home. When you are ready to discuss a new air conditioning installation, we are ready to help you choose, size, and install a system built to keep you comfortable for years to come.
