AC Installation & Replacement
We install new central AC systems and replace worn out units, sized with a real load calculation to fit your home and budget.
AC installation is the full replacement of your cooling system: a new outdoor condenser, a matched indoor coil, and a proper setup of the ductwork, refrigerant, and electrical. Done right, a new system cools better and costs less to run. The Cool Guy HVAC sizes, installs, and tests every system for your exact home.
We handle the whole job: honest sizing, clean removal of the old unit, and a careful install of the new one. It is one part of our full range of air conditioning services for homes across the San Gabriel Valley.
New AC Installation for Your Home
Every good install starts before the equipment shows up. We do a load calculation, the math that finds the right system size for your home. We check your ductwork and your electrical panel. Then we match an outdoor condenser and an indoor coil that work together as one system.
On install day we remove the old unit, set the new equipment, connect the refrigerant lines and wiring, and run a full test before we leave. If your home has no ducts, a ductless mini split system may be the better fit.
When Should You Replace Your Air Conditioner?
Replace your AC when the repair bills keep coming, when the unit is well past its expected life, or when it uses an old refrigerant that is being phased out. At that point, AC replacement usually beats another repair, because a new system cools better and uses less power.
Watch for the common signs: most central AC units last about 12 to 15 years, so age matters. So does a repair every summer, power bills that keep climbing, or rooms that never get cool. If the problem is small and the unit is younger, a fix may be all you need. Our AC repair team can tell you which side you are on.
What SEER2 Rating Should Your New AC Have?
SEER2 is the efficiency score on every new air conditioner. A higher SEER2 means the system uses less electricity to make the same cool air. Higher efficiency costs more up front and saves money every month you run it.
There is no one right answer for every house. A home that runs the AC hard all summer gets more value from high efficiency than one that rarely uses it. We explain the options in plain terms with your free estimate, so you can pick with clear eyes.
Ductwork and Wiring: The Parts of an Install You Do Not See
A new AC is only as good as the ducts and wiring behind it. Leaky or crushed ducts waste the cool air you paid for. An electrical panel that cannot safely handle the new unit is a real problem. We check both before we install anything.
If your ductwork needs sealing or repair, we tell you up front and price it clearly, with no surprises on install day. Keeping the whole system healthy is also why yearly AC tune ups matter after the install.
Already Have a Quote From Another Company?
Bring it to us before you sign. We offer HVAC second opinions on replacement quotes, and we will tell you plainly if the size, scope, or price looks off. Sometimes the other quote is fair. Sometimes you only need a repair, not a new system. Either way, you decide with better information.

FAQ
AC Installation & Replacement, common questions
Where can I find AC installation near me in La Puente?
The Cool Guy HVAC installs and replaces AC systems for homeowners in La Puente and the nearby cities of Whittier and Hacienda Heights. We are family owned and locally operated, and we keep our service area small so every install gets full attention. Call (562) 589-2485 or request a free estimate online.
What makes a new AC installation cost more or less?
The size of the system moves the price most. A bigger home needs more tonnage, which is the measure of cooling power. After that, the SEER2 efficiency rating, the condition of your ductwork, any electrical upgrades, and local permit fees all move the number. That is why we quote in person with a free estimate instead of guessing over the phone.
What does your AC installation warranty cover?
Every install comes with a 10 year manufacturer warranty on the equipment and a 1 year labor warranty on our work. The equipment warranty comes from the maker of your system and covers the unit itself. The labor warranty is ours. If something about the install needs fixing in the first year, we come back and make it right at no charge.
How long does it take to install a new AC unit?
A standard AC replacement usually takes about one day. The crew removes the old unit, sets the new condenser and coil, connects the refrigerant lines and wiring, and tests the system before leaving. Jobs that include ductwork repairs or electrical upgrades can take longer. We tell you the expected timeline with your free estimate, before any work starts.
What size AC unit do I need for my house?
The right size comes from a load calculation, not a guess. That is the math that weighs your home's square footage, insulation, windows, and sun exposure. A system that is too big cools fast but leaves the air sticky and wears out sooner. One that is too small runs nonstop. We size every system before we quote it.
Do I need a permit to install a new AC?
In most cities, yes. Replacing a central AC system usually needs a mechanical permit, and the work gets inspected after the install. Permits protect you, because they confirm the electrical, refrigerant, and safety work was done to code. Ask about permits when you get your estimate, and we will walk you through what your city requires.
