Work with our Comfort Consultants

Our team of Comfort Consultants will help you find the right system for your home, needs and budget. Finding the right size unit for your home is the first step. When installing a new AC system, Constellation Home’s team of experts will measure your home to determine the appropriate unit size for peak efficiency and effectiveness.

An air conditioning system operates by extracting hot, humid air from inside your house and distributing cool, conditioned air throughout your home. If a unit is too small, it won’t efficiently cool your house. And, if it’s too big, it can waste energy and money. Our professionals will evaluate your home size, climate, insulation, ductwork and more to determine the right size to fit your needs.

AC Installation around Your Schedule

Once a unit is selected, our certified professionals follow rigorous guidelines to ensure a superior installation. Our team will also manage all permitting for the installation so that you don’t have to worry about any paperwork. Constellation Home will make sure that your AC installation day is stress free and efficient. We also will make sure that any necessary inspections are passed before your job is closed.
