How Much Does It Cost To Install Central Air Conditioning?

Installing central air conditioning with G&C Plumbing & Heating is custom-priced after an in-home evaluation. The biggest cost driver is the system size your home actually needs and whether your existing ductwork can be used or must be added or corrected.

We help you choose the right equipment and follow manufacturer specs from removal to final testing, then back the work with a 2-year warranty (4 years for Club Members). Our team frequently handles central AC projects in the greater Boston area, giving practical guidance on options without surprises in the estimate. Financing is available, and we can help identify rebate programs such as Mass Save.

When pricing your project, we assess:

• Ductwork condition or the need for new ducts
• Efficiency level and comfort features
• Electrical upgrades and line-set routing
• Thermostat and indoor air quality add-ons
