What does an AC install cost in Connecticut?

  • Low: $6,000
  • Median: $11,500
  • High: $17,000

What factors affect the cost of an AC install?

The price of an AC install varies based on three main factors: the system purchased, the need for home renovations and the contractor you hire to perform the work.

  • AC system cost: The cost of the AC itself can vary significantly depending on the system's efficiency rating (rated by SEER), cooling output (measured in tons) and type of system installed. At Aiello, we install all of the industry's most reputable brands. That gives us leeway to find the perfect system at the right price point for each customer.
  • Home renovations: Modifying the plumbing, electrical or ductwork of an existing home is sometimes necessary to accommodate a new AC system. The good news is, since Aiello has in-house pros for all of the above, you won't need to rely on subcontractors, who may not abide by the same high standards that Aiello does for its technicians.
  • The contractor you hire: Pricing for AC installations vary from contractor to contractor. These rates are based on a contractor's experience, skill level, training and other factors. The EPA estimates that as many as half of all AC systems are installed incorrectly by inexperienced contractors. That's why going with a company you know will get the job done right is always the best choice.

Our 5-star AC replacement process

  1. We perform a free in-home estimate

    At Aiello, we want every customer to feel confident when they purchase a new AC system. That's why we send one of our expert comfort specialists to your home to perform a thorough in-home walkthrough and load calculation, completely free of charge. For additional peace of mind, we send every customer a bio and picture of their comfort specialist prior to their arrival along with an easy link to follow them on their way to your home.

  2. We share a variety of replacement options

    After the walkthrough is complete, we work closely with each customer to pick out the perfect HVAC system for them, based on the needs of their home and budget. Aiello installs hundreds of different types of systems every year and has a larger selection of brands and models than any other contractor in Connecticut. More options means more chances to identify a system that meets the comfort, convenience and budget needs of our customers.

  3. We prepare for a successful AC installation

    When it comes to preparing for your AC installation, you barely have to lift a finger. Aiello will help you apply for Energy Star rebates and tax credits that pertain to your new system, and assist you with financing upon request. We'll also plan out the installation ahead of time to ensure everything is in place on installation day.

  4. We give you a 5-star installation experience

    Aiello can complete most AC installations in just one day. That speed is a tribute to both the training and preparation each install team goes through before arriving at a customer's home. During the install, shoe covers are worn, drop cloths are placed on the floor and the entire system is thoroughly tested before we leave.

Your satisfaction means the world to us

Our goal is to give every Aiello customer a 5-star experience. That's why we ask if we delivered 5-star service at the end of every job. If not, we'll do everything we can to correct that issue before we leave.
