What AC Installation Actually Involves

More than setting a unit outside and connecting a few wires.

Equipment Assessment

We check square footage, ductwork, and insulation. Undersized never cools properly; oversized short-cycles and leaves the air humid.

Old Unit Removal

We remove the old equipment to EPA refrigerant handling requirements. No separate disposal to arrange.

Full System Installation

We set the condenser, connect the air handler or coil, run and insulate refrigerant lines, and test the system under load before we leave.

Thermostat Pairing

We connect the new unit to a smart thermostat or replace an outdated one in the same visit.

Operational Walkthrough

We cover filters, maintenance intervals, and warning signs, which heads off most first-year service calls.

Permit and Code Compliance

Plainfield requires permits for HVAC installation. We handle the paperwork so the job is documented for a home sale or insurance claim.

Why It Matters

DIY AC Installation Costs More Than It Saves

Installing central air without the right certification is illegal in Illinois for the refrigerant handling alone. A wrong refrigerant charge, loose duct connections, or an undersized disconnect box will fail early, and the damage rarely stops at the AC equipment. Most manufacturer warranties also require licensed installation. We don't subcontract. The technician who shows up is a Leto employee, background-checked and trained on the equipment we install.

How Plainfield Homes Affect the Installation

Subdivisions built in the 2000s and 2010s usually have ductwork and panels sized for modern HVAC. Older homes near downtown and some early ranch builds went up before central air was standard and need more planning. Will County's hard water speeds mineral buildup in water heaters and in humidifier attachments on the air handler, so we check those connections. With past basement water issues, we confirm the condensate drain discharges safely. Our plumbing services cover that side of the house too.

What Plainfield Homeowners Ask About AC Installation

How long does an AC installation take in a Plainfield home?

With existing ductwork and a standard central system, four to six hours. Ductwork modifications or panel upgrades take longer. If something unexpected comes up, we call you before adding any scope.

Do I need a permit for AC installation in Plainfield, IL?

Yes. Plainfield requires permits for HVAC installation and the electrical work tied to it, and we handle the permitting. Unpermitted HVAC work can complicate a home sale in Will County and may affect your homeowner's insurance if there's ever a claim.

My Plainfield home is older and doesn't have central air. Can you still install it?

Yes. Older homes may need added ductwork or a panel upgrade. In some older Plainfield homes a ductless mini-split is more practical than running new ducts. We'll tell you which fits your layout.

Does Leto Plumbing & Heating handle both the HVAC and plumbing in a Plainfield home?

Yes. We handle heating system installation and repair, AC installation, and residential plumbing, including sump pumps, water heaters, and drain work. One call to (815) 609-3150 covers it.
