Your AC Installation Questions, Answered
Choosing a new air conditioning system is a big decision, and we’re here to make it easier. These common questions from Jefferson and Shelby County homeowners can help you understand when to install, what to expect, and how to get the most out of your new AC.
Most residential AC installations take just one day from start to finish. This includes removing the old unit, prepping the space, and professionally installing your new system. What that means for you, the homeowner, is cooler air with less waiting.
That said, more complex homes or custom installations may take longer. We’ll give you a clear timeline during your estimate so there are no surprises.
Professional installation ensures your system is the right size, properly connected, and ready for efficient cooling from day one. Benefits include:
A professional setup can mean better cooling and a longer system life.
If your system is 10-15 years old and you’re facing frequent or costly repairs, it may be time to consider replacement. Even if it’s still running, it may be running inefficiently.
You can also look at energy bills, performance, and cooling consistency. If your AC struggles to keep up or breaks down often, it’s likely more cost-effective to replace than repair.
The size of your new system depends on several factors beyond square footage. Insulation levels, ceiling height, number of windows, and even sun exposure all play a role.
That’s why we perform a full home evaluation to recommend the most efficient unit. Bigger isn’t always better as oversized systems can lead to short-cycling and poor humidity control.
A complete installation includes more than just swapping out equipment. You’ll receive:
Everything is handled by licensed pros who take care of your home like it’s their own.
