AC Installation Process

Here's How We Handle Installation

First, we come out to assess your home and current setup. We measure spaces, check existing ductwork, and calculate the right system size. No guessing – we use actual load calculations to determine what you need.

Next, we provide a written estimate that breaks down equipment, labor, and any additional work required. You’ll know exactly what you’re paying for before we start.

On installation day, we protect your floors and furniture, then remove your old system safely. The new AC unit goes in with proper connections, testing, and cleanup. We walk you through the new system operation and leave you with warranty information and our contact details for any questions.

How long does central AC installation typically take?

Most central air conditioning installations take one full day, sometimes extending into a second day depending on your home’s setup. Straightforward replacements where existing ductwork is in good condition usually finish in 6-8 hours. If we need to modify ductwork, run new electrical lines, or handle complex installations, it might take 1-2 additional days. We’ll give you a realistic timeline during the estimate so you can plan accordingly. Weather can also affect timing since part of the work involves outdoor equipment installation.
AC sizing depends on your home’s square footage, insulation levels, window placement, and local climate conditions. We perform detailed load calculations rather than using rough estimates or rules of thumb. An oversized unit will cycle on and off too frequently, wasting energy and failing to remove humidity properly. An undersized unit will run constantly and struggle to cool your home. Most homes in our area need between 2-5 tons of cooling capacity, but the only way to know for sure is through proper calculation of your specific home’s cooling requirements.
Yes, we take care of all required permits and coordinate inspections as part of our installation service. Allenwood requires permits for most HVAC installations, and we’re familiar with local code requirements. We submit permit applications, schedule required inspections, and ensure everything meets current standards. This protects you from potential issues down the road and ensures your installation is done legally and safely. The permit costs are included in our installation estimates so there are no surprise fees.
We handle complete removal and proper disposal of your old AC equipment as part of the installation service. This includes safely recovering refrigerant according to EPA regulations, disconnecting electrical and refrigerant lines, and removing both indoor and outdoor units. Old equipment contains materials that require proper disposal, including refrigerants that can’t just be released into the atmosphere. We have the proper equipment and certifications to handle this safely and legally, so you don’t have to worry about disposal or potential environmental violations.
Central AC installation costs vary based on system size, efficiency rating, and installation complexity. Basic installations typically start around $3,500-$5,000 for standard efficiency units, while high-efficiency systems can range from $5,000-$8,000 or more. Factors affecting price include ductwork modifications, electrical upgrades, permit fees, and equipment brand selection. We provide detailed written estimates that break down all costs so you understand exactly what you’re paying for. Financing options are available for qualified customers to help manage the investment.
New AC installations come with both manufacturer equipment warranties and our labor warranty. Equipment warranties typically cover parts for 5-10 years depending on the brand and model you choose. Our installation labor is warranted for one full year, covering any issues related to our workmanship. We also provide ongoing service and maintenance to keep your warranty valid and your system running efficiently. All warranty terms are clearly explained in writing, and we handle warranty claims directly with manufacturers when needed.
