The independent heating and cooling company across Kentucky and the Ohio Valley
AC Installation — Book a Visit Today
We install central air conditioning systems, replace worn-out AC units, and put in ductless mini-splits for homes across Illinois, Indiana, Kentucky, Ohio, Tennessee and West Virginia. Most replacements start the same way: a system in its teens or twenties that needs refrigerant every summer, a compressor that finally quit, or rooms the old ductwork never reached. A visit begins with load and airflow, not a sales sheet. We measure the house, look at duct sizing and return air, check the electrical supply and the condensate path, then talk through what fits your rooms and your budget. Installation day includes protecting floors, setting the new equipment level, commissioning the charge, and showing you the thermostat before we leave. Call us to book an in-home assessment.

The AC installation symptoms we hear most
- My AC is over 15 years old and I keep patching it End-of-life equipment, repeat repair costs approaching replacement
- It needs a refrigerant top-up every single summer Leaking coil or line set, often on older R-22 systems no longer supported
- The upstairs never gets cool no matter what I set Undersized or leaky ductwork, poor return air, wrong equipment capacity
- The compressor died and they said it isn't worth fixing Major component failure on an aged outdoor unit
- We finished the attic and there's no ductwork out there Added conditioned space with no supply, a common ductless mini-split candidate
Whether you call it AC installation, air conditioner installation or AC replacement, the work is identical and so is the quote you approve first.
Safe things to check first
Worth a look before you call — sometimes it saves you the visit.
- 1Check the thermostat: fresh batteries, set to cool, and the fan set to auto rather than off.
- 2Look at your electrical panel for a tripped breaker on the air conditioner or air handler circuit.
- 3Change the filter if it is grey and matted, since a clogged filter can look like a failing system.
- 4Clear grass, leaves and shrub growth back from the outdoor unit so air can move through the coil.

How do I know whether to repair or replace my AC?
We look at the age of the equipment, whether refrigerant is leaking, and what the repair costs against a new system. If a unit is well into its teens and losing refrigerant yearly, replacement usually makes more sense than another patch.
Do you size the system or just match what's there?
We calculate the load for your house rather than copying the old nameplate. Windows, insulation, ceiling height and duct capacity all matter. Homes that were re-roofed, re-windowed or added onto often need a different capacity than the original equipment.
Can my existing ductwork be reused?
Often yes, but we inspect it first. Undersized returns, crushed flex runs and disconnected joints in crawlspaces are common across the region. We tell you what needs repair or resizing before installation so airflow matches the new equipment.
How long does an AC replacement take?
Most straightforward changeouts are a single day. Jobs that involve duct modifications, electrical work, a new line set or moving the outdoor unit can run into a second day. We give you a schedule before we start.
When does a ductless mini-split make more sense?
Mini-splits work well for finished attics, garages, sunrooms, additions and older houses with no practical route for ductwork. They also let you condition one stubborn room without oversizing the whole system for the rest of the house.
Do you replace the outdoor and indoor units together?
Generally yes. The outdoor condenser and indoor coil are designed to work as a matched pair, and mixing old with new usually hurts capacity and reliability. We explain the exception cases during the assessment.
How it works
- Step 1
Tell us the symptom
Call or fill in the quote form. We ask what changed, when it started, and what the thermostat reads. That short conversation tells us whether you need a visit today or tomorrow morning.
- Step 2
We diagnose on site
A technician checks the thermostat, the electrical side, airflow through the filter and ducts, and the equipment itself. We find the actual cause instead of swapping parts and hoping the noise goes away.
- Step 3
You decide before we work
We explain what failed, what the repair involves, and what we would do if it were our own house. Nothing gets replaced until you say go. Then we test the system before leaving.

Why homeowners call us
- Old houses and new onesWe are used to century-old homes with retrofitted ductwork and 1970s subdivisions with original returns. Tight crawl spaces, low basement headroom and odd attic runs are normal parts of the day for us, not surprises that stall the job.
- Built for the swingsHumid summers push AC systems hard and January freezes expose weak igniters and cracked flues. We repair for both extremes across the region, so the fix holds when the weather turns instead of failing the first hard week.
- Air conditioning and heating bothAir conditioner repair in July, heating repair in January, and the IAQ and airflow problems that hide in between. One crew that knows how your cooling and heating share the same blower and the same duct system.
- Plain talk, no pressureWe tell you when a repair makes sense and when replacement is the honest answer. No scare tactics about your BTU load, no upsell scripts. You get the condition of the system and a clear next step.

- Straight answersIf a system is not worth repairing, we say so, often right on the phone.
