Accurate Cooling Load Calculation for Air Conditioner Installation

Not all air conditioners are created alike, and your home has unique cooling needs. That’s why air conditioning installation service starts with calculating your home’s cooling load to design a system that’s sized accurately.

When you schedule an installation appointment with our HVAC technicians, we’ll begin by assessing your home’s size, layout, orientation, and several other key factors. We’ll make a note of how many windows your home has, which direction they face, and whether your home receives substantial shade. With this data in hand, we’ll use HVAC industry standard software to determine the size of the system your home needs.

As we design the ideal system for your home, we’ll also consider any ductwork modifications needed. After all, ductwork is a key component of any HVAC system, and upgrading or extending your ducts can go a long way toward optimal energy efficiency.

Help with Choosing the Ideal Air Conditioning System

Next, we’ll talk with you about the ideal cooling systems for your home. We offer a range of air conditioning systems, and each offers attractive benefits. Whether you’re looking for the system with the highest seasonal energy efficiency ratio (SEER) rating, the most built-in indoor air quality components, or integrated control thermostats, we’ll point you in the right direction.

Want to make sure your new cooling system has all the latest high-tech features? We have you covered. Confused about cooling system brands? We’ll highlight the differences so you’re confident about the one you choose.

Need more information so you can understand the difference between an air conditioner and a heat pump? Our team will happily walk you through the benefits of both types of cooling systems to help you make the right decision for your home.

Professional Air Conditioning Installation Every Step of the Way

Once our HVAC technicians have worked with you to choose the right cooling system for your home, we’ll schedule an AC installation service appointment. You’ll understand exactly what to expect throughout the installation process, whether it’s a simple system that we can complete in a day or two or a complex system that takes several days.

When we finish the installation process, we won’t leave you hanging. We know that every air conditioner works differently, so we’ll walk you through the basic operations and settings. Whether you opted for a basic programmable thermostat or a high-tech smart thermostat, we’ll show you how to set the right temperature and keep your new air conditioner energy efficient.
