Everyone sizes air conditioning for temperature. In the Ohio Valley the bigger comfort problem is moisture. An air conditioner removes humidity by running long enough for the coil to stay cold and pull water out of the air — and an oversized unit cools the thermostat quickly, shuts off, and never runs long enough to dehumidify.
That is why a house with a brand new, too-large system can feel worse than it did with the old one. It hits temperature and still feels damp. Bigger is not better in this climate; correctly sized is.
What we do
Diagnostic and repair on any brand — capacitors, contactors, compressors, blowers, control boards
Refrigerant leak detection and repair rather than repeat top-ups
Full system replacement, including matched coil and air handler
Proper load calculation before quoting equipment
Ductless mini-splits where ductwork is not practical
Condensate drain, pan and float switch work
Repair or replace
We will give you the arithmetic rather than a recommendation dressed up as one. Age, what failed, the cost of the repair, and what a replacement would actually save you. A capacitor on a twelve-year-old system is worth doing. A compressor on a twenty-year-old system is usually money spent on a replacement you are making anyway.
The refrigerant change
New residential systems in the US moved to A2L refrigerants such as R-454B from 2025, replacing R-410A. If your system is on R-410A it is not obsolete and it is not illegal — but supply of the older refrigerant tightens over time, which is worth factoring into a repair-versus-replace decision on an ageing unit. We will tell you where your system sits.
How we work
Diagnosis before parts
The fastest way to spend your money badly is to replace components until the symptom goes away. We measure first.
We take readings. Pressures, temperature split, electrical values — not a guess based on what usually fails.
You see what we found. If a part is out of spec we will show you the number, not just the invoice line.
You get the arithmetic. Repair cost against replacement cost against remaining life. Then you decide.
No scare selling. If your system has years left in it we will say so, even when a replacement would be the bigger ticket.
Why is my new AC cooling but the house still feels damp?
Almost always because it is oversized. It reaches the thermostat setpoint fast, shuts off, and never runs long enough to pull moisture out of the air. In the Ohio Valley that is the single most common comfort complaint, and it comes from sizing on square footage instead of doing a load calculation.
How long should an air conditioner last here?
Commonly around fifteen years, sometimes longer with maintenance. Systems that short-cycle or that have never been serviced tend to fall short of that.
Do I need to replace the furnace at the same time as the AC?
Not always, but the indoor coil has to be matched to the outdoor unit, and if the furnace is a similar age it is often cheaper to do both than to pay two separate labour visits a few years apart. We will tell you which applies to your system.
