Professional AC installation covers everything from initial assessment to final testing and cleanup. This includes proper sizing calculations, electrical work, refrigerant line installation, and ductwork modifications if needed.

Most residential AC installations take 6-8 hours for a direct replacement, though this can vary based on your home’s specific needs. If you’re upgrading from window units to central air, or if electrical work or ductwork modifications are needed, the installation might take a full day or require a second visit. We’ll give you a realistic timeline during the initial assessment so you can plan accordingly. We work efficiently while making sure every connection is proper and the system is thoroughly tested before considering the job complete.
AC sizing depends on your home’s square footage, insulation, window placement, and local climate factors specific to Massachusetts. A unit that’s too small won’t keep you comfortable during peak summer heat, while an oversized unit will cycle on and off frequently, wasting energy and creating humidity problems. Professional sizing involves calculating your home’s actual cooling load, not just using rough square footage estimates. We’ll measure your space, evaluate insulation and windows, and recommend the right capacity system that will run efficiently and keep your home consistently comfortable.
Yes, most AC installations in Attleboro require permits, especially if electrical work is involved or you’re installing a new system rather than replacing an existing one. The permit process verifies the installation meets local building codes and safety standards. We handle permit applications and scheduling inspections as part of our service, so you don’t have to navigate the paperwork yourself. This protects you legally and makes sure the work is done to code, which is important for insurance coverage and future home sales.
Absolutely. Many older homes in Attleboro can accommodate central air through ductless mini-split systems or by adding ductwork where feasible. Ductless systems are often the most practical solution for older homes because they don’t require major renovations and can provide efficient cooling to specific areas. If traditional ducted systems are preferred and space allows, ductwork can sometimes be routed through basements, attics, or closets. Our assessment will determine what options work best for your home’s layout and your comfort goals while staying within your budget.
Professional installations come with warranty coverage on both the equipment and the installation work itself. If issues arise, the first step is determining whether it’s a manufacturer warranty issue or an installation-related problem. We stand behind our work and will return to address any installation-related issues at no charge. Equipment warranties typically cover parts for several years, with some components like compressors having longer coverage periods. Having a relationship with us through programs like the Dempsey Comfort Club assures you have ongoing support and priority service when needed.
AC installation costs vary significantly based on system type, home size, existing infrastructure, and specific installation requirements. Basic central air replacement might cost less than a tedious installation requiring new ductwork or electrical upgrades. Ductless systems have different cost structures than traditional central air. The best approach is getting a detailed estimate that breaks down equipment, labor, permits, and any additional work needed. This gives you a clear picture of the investment and helps you make an informed decision based on your budget and comfort needs rather than trying to guess from general price ranges.
