Here's How We Handle Your Installation

We start with an in-home assessment to determine the right system size and type for your space. This isn’t a quick measurement—we calculate your home’s cooling load based on square footage, insulation, windows, and local climate factors.

Once you approve the system selection, we schedule your installation at a time that works for you. Our technicians arrive with all necessary equipment and materials, so there are no delays waiting for parts or supplies.

The installation typically takes one full day for most homes.

How long does AC installation take in Brookline homes?

Most air conditioner installations in Brookline take 6–8 hours to complete. The exact time depends on your home’s specific requirements, such as ductwork modifications or electrical upgrades. Older homes in the area sometimes need additional work to accommodate modern systems, which can extend the timeline to a full day or two days for delicate installations. We’ll give you a clear timeframe during our initial assessment so you know exactly what to expect.

What size AC unit do I need for my home?

The right AC size depends on your home’s square footage, insulation quality, window placement, and ceiling height. Many Brookline homes have unique layouts that require careful calculation to avoid oversizing or undersizing the system. An oversized unit cycles on and off too frequently, wasting energy and failing to remove humidity properly. An undersized unit runs constantly and never reaches your desired temperature. We perform a detailed load calculation to determine the exact capacity your home needs for optimal comfort and efficiency.

Do you handle permits for AC installation in Brookline?

Yes, we handle all necessary permits for air conditioning installation in Brookline. Most AC installations require electrical permits, and some may need building permits depending on the scope of work. We’re familiar with Brookline’s permit requirements and inspection processes, so you don’t have to navigate the paperwork yourself. The permit costs are typically included in your installation quote, and we coordinate with local inspectors to make sure everything meets code requirements.

Can you install AC in homes without existing ductwork?

Absolutely. Many older Brookline homes don’t have central air conditioning or adequate ductwork for modern systems. We can install new ductwork throughout your home or recommend ductless mini-split systems that don’t require traditional ducts. Ductless systems are particularly effective in historic homes where adding ductwork might be challenging or expensive. We’ll assess your home’s layout and recommend the most practical and cost-effective solution for your specific situation.

What warranty comes with your AC installation work?

Our AC installations include both manufacturer warranties on the equipment and our warranty on the installation workmanship. Equipment warranties typically cover parts for 5-10 years, depending on the brand and model you choose. Our installation warranty covers all labor and verifies that any issues related to our work are resolved at no additional cost to you. We also offer extended warranty options and maintenance plans through our Dempsey Comfort Club to keep your system running smoothly long-term.

How much does AC installation cost in Brookline?

AC installation costs vary based on system size, efficiency rating, and your home’s specific requirements. Basic installations for standard homes typically start around $3,000-$5,000, while high-efficiency systems or lengthy installations can cost more. Factors that affect pricing include ductwork modifications, electrical upgrades, and permit requirements. We provide detailed written estimates that break down all costs so you understand exactly what you’re paying for. Our estimates include equipment, labor, permits, and cleanup—no surprise charges later.
