AC Installation Process Randolph

Straightforward Installation, Professional Results

Your AC installation starts with a thorough assessment of your home’s cooling needs. This includes measuring square footage, checking insulation levels, evaluating existing ductwork, and calculating the proper system size. Getting this step right prevents the common problems of oversized or undersized units.

Next comes the actual installation work. The old system gets removed properly, electrical connections are updated to code, and the new equipment is positioned and connected. This includes both the indoor air handler and outdoor condenser unit, plus all the refrigerant lines and controls.

The final step involves testing everything to make sure it’s working correctly, walking you through the new system’s operation, and setting up any warranty information. You’ll know exactly how to operate your new AC and what to expect for maintenance going forward.

How long does AC installation take in Randolph homes?

Most residential AC installations take 6-8 hours for a straightforward replacement, but can extend to a full day or more if electrical upgrades or ductwork modifications are needed. Older Randolph homes sometimes require additional work to bring electrical systems up to current codes or to address accessibility issues. Our installation team will give you a realistic timeline during the initial assessment, and we’ll keep you updated if anything changes during the work. Same-day completion is the goal for most installations, but we won’t rush the job just to meet an arbitrary deadline.

What size AC system do I need for my home?

AC system sizing depends on your home’s square footage, insulation levels, window placement, ceiling height, and local climate factors. A proper load calculation takes all these variables into account to determine the right capacity. Many homeowners assume bigger is better, but oversized units actually create problems like poor humidity control and frequent on-off cycling. Undersized units run constantly and never quite reach comfortable temperatures. Our installation team performs these calculations as part of every installation to ensure your new system matches your home’s specific cooling requirements.

Can you install AC in homes without existing ductwork?

Yes, there are several options for homes without existing ductwork. Ductless mini-split systems are popular because they don’t require extensive modifications to your home’s structure. These systems use individual indoor units connected to an outdoor condenser, with only small refrigerant lines running between them. For homes where traditional central air is preferred, new ductwork can be installed, though this is more involved and expensive. The best approach depends on your home’s layout, your budget, and your comfort preferences. An assessment will help determine which option makes the most sense for your situation.

What happens to my old AC system during replacement?

We completely remove and dispose of your old AC system properly, including refrigerant recovery as required by environmental regulations. This includes both the indoor and outdoor components, along with old refrigerant lines if they’re being replaced. Any reusable materials are recycled appropriately. We clean up the installation area, and you won’t be left dealing with old equipment or debris. Some older systems contain refrigerants that require special handling, which is all taken care of as part of the installation process. You don’t need to worry about disposal logistics or environmental compliance issues.

Do I need permits for AC installation in Randolph?

Most AC installations in Randolph require permits, especially if electrical work is involved or if you’re installing a new system rather than replacing an existing one. Our installation team handles permit applications and ensures all work meets local building codes. This includes electrical connections, refrigerant line installation, and proper equipment placement. Having permits and inspections protects you by ensuring the work is done safely and correctly. It also prevents potential issues if you sell your home later. The permit process is built into the installation timeline, so it won’t cause unexpected delays.

What warranty comes with new AC installation?

New AC systems typically come with manufacturer warranties on equipment that range from 5-10 years depending on the specific components. Installation labor is warranted separately, usually for 1-2 years, covering any issues related to the installation work itself. This means if something goes wrong due to installation errors, it gets fixed at no charge. Equipment warranties cover manufacturing defects and component failures under normal use. Extended warranties are often available for additional coverage. All warranty information is provided in writing after installation, including what’s covered, how long coverage lasts, and how to access warranty service.
