Common Homeowner Questions About New AC installs
What size AC system do I need for my home?
Air conditioners are sized in “tons,” which refers to the amount of heat they can remove per hour. Choosing the right tonnage is critical—too small and your system won’t cool effectively; too large and it may short-cycle, wasting energy and reducing comfort. We calculate the correct size using ACCA Manual J guidelines, factoring in your home’s size, layout, insulation, and more.
Is a high-efficiency air conditioner worth the investment?
Yes—especially for new system installs. High-efficiency AC units (20 SEER or higher) cost more upfront but can significantly lower your monthly utility bills. Over time, the savings often outweigh the initial cost. Plus, you’ll enjoy quieter operation, better humidity control, and reduced environmental impact. We install efficient, high-performance systems from top brands like Carrier.
Do I need to replace my ductwork when installing a new AC system?
It depends. If your existing ducts are old, leaking, or not properly sized, they can hurt the performance of your new system. Our team will inspect your ductwork and let you know if any updates are needed to ensure efficient airflow and comfort throughout your home.
Will a larger air conditioner cool my home faster?
Not always. An oversized unit may cool the air quickly but shut off before it can properly dehumidify your home, leading to uneven temperatures and a clammy feeling. We follow ACCA Manual J guidelines to size your system accurately based on your home’s layout, insulation, windows, and more.
How long does a new AC installation take?
Most air conditioner installations can be completed in a single day. If you’re also installing or modifying ductwork, zoning systems, or smart thermostats, it may take a bit longer. We’ll walk you through the entire process and timeline up front.
What kind of warranty comes with my new AC system?
At HVAC & Plumbing Unlimited, we install Carrier air conditioning systems backed by strong manufacturer warranties—typically up to 10 years for parts when registered. As a Carrier Factory Authorized Dealer, we ensure your system is installed to meet warranty requirements. We’ll walk you through the registration process and explain what’s covered so you can feel confident in your investment.
