About Lexington Heating and Air

Lexington Heating and Air exists to close one gap: the distance between what the meter actually shows and what a homeowner gets told. Picture the version that sends people looking for a second opinion — a furnace condemned over a “cracked heat exchanger” the homeowner was never shown, paired with a five-figure quote to replace the whole system, when the real fault is a cracked hot surface igniter and a condensate trap packed with scale: an afternoon’s work and a small fraction of the price. That gap is the reason this company exists. William Gamino founded it in 2015 on the opposite principle — read the meter, show the customer the number, and quote what the number says.

The Owner — William Gamino

William owns and operates Lexington Heating and Air from its shop at 343 Cassidy Ave, a mile and a half from downtown. He holds Kentucky HVAC Contractor License #HM04788 through the Department of Housing, Buildings and Construction, and is EPA Section 608 Universal certified, which covers handling R-22, R-410A, and R-454B refrigerants.

William grew up in central Kentucky and came into the trade through a five-year apprenticeship before earning his contractor’s license in 2011. He spent several years running service calls for a larger regional outfit, where he watched the same pattern repeat: aging homeowners pressured into full system replacements they didn’t need. In 2015 he founded Lexington Heating and Air on the opposite principle — diagnose first, quote the actual problem, and treat a repairable system as exactly that. He still runs calls himself.

The discipline shows in how a visit runs. A run capacitor reading 28 microfarads against a 35-rated label is a fourteen-dollar fix. The same symptom with the compressor pulling locked-rotor amperage is a different conversation entirely. Most outfits quote the second number for both. We read the meter, show you the number, and quote what the number says. That is the whole method.

Why the Bluegrass Breaks Generic HVAC

Lexington is not the dry Mountain West, and it is not the Deep South. Equipment sized and tuned for either underperforms here — and the reasons are physics, not opinion.

Humid Summers and the Latent Load

Picture the worst version of it: a July afternoon, the thermostat reads 72, and the house still feels like a damp towel. That is an oversized air conditioner failing at its second job. Cooling does two things at once — it drops temperature (sensible load) and wrings out moisture (latent load). Lexington summers pair high heat with dew points in the upper 60s and low 70s, so the latent load is enormous. An oversized unit satisfies the thermostat in a short, hard blast and shuts off before it can dehumidify. Right-sizing for latent capacity, not just tonnage, is the difference between cool-and-clammy and genuinely comfortable.

Limestone, Hard Water, and What It Costs You

The entire region sits on a thick shelf of Ordovician limestone — the same geology that makes the Bluegrass famous for horses and bourbon. It also makes the water hard. Lexington’s municipal supply, drawn largely from the Kentucky River and Jacobson Reservoir, carries real calcium carbonate hardness, and that mineral load does measurable damage: it scales humidifier pads and steam canisters months ahead of their rated life, and it builds biofilm-bound deposits in evaporator condensate drains until they clog and overflow. Equipment selected without accounting for water chemistry fails on a schedule no warranty covers.

Climate Zone 4A — the Mixed-Humid Middle

The 2021 IECC places Fayette County in Climate Zone 4A, mixed-humid. That label carries weight: 4A sits on the boundary where neither a heating-dominated nor a cooling-dominated design assumption holds cleanly. Winters bring cold, damp spells that drive genuine heating demand; summers bring sustained humidity that drives latent cooling demand. Heat pumps make excellent sense in this zone — but only when they’re sized for the January cold snaps Lexington actually sees, not the optimistic mild-day rating stamped on the box.

Century Homes Beside New Builds

Few cities mix housing stock the way Lexington does. The brick homes of Ashland Park, Chevy Chase, and Kenwick were built between the 1900s and 1940s — plaster walls, original ductwork, sometimes a gravity furnace converted decades ago. Push out toward Hamburg, Andover, or Beaumont and you find tight, well-insulated construction carrying a fraction of the heating and cooling load per square foot. A system sized by rule of thumb gets one of those two wrong almost every time. We size by calculation instead.

What We Do

Residential and commercial HVAC across Fayette County, with real depth in the categories our climate stresses:

Furnace installation and repair — single-stage, two-stage, and modulating gas furnaces, with combustion analysis and proper venting on the older homes that need it.
Air conditioning installation and repair — equipment weighted for Bluegrass latent load, plus capacitor, compressor, and refrigerant service.
Heat pump systems — well-matched to Climate Zone 4A, sized to real Lexington winter design temperatures.
Indoor air quality — whole-home dehumidifiers, humidifiers, air purifiers, UV-C coil treatment, and filtration matched to a humid climate.
Boiler and hydronic systems — repair and installation for the radiant and steam systems still common in historic Lexington homes.
Commercial HVAC — rooftop units, maintenance, and service contracts for Fayette County offices and small commercial properties.

Our Comfort Club Maintenance Plan keeps systems ahead of the wear our climate causes: two annual tune-ups (spring cooling, fall heating), priority scheduling, 10% off repairs, condenser coil inspection, electrical testing, condensate drain cleaning, thermostat calibration, and a written performance report each visit. Financing is available for qualified customers on larger repairs and installations.

How We Work

Diagnose before quoting. Measure before forming an opinion. Price in daylight — every estimate broken out into equipment, labor, permit fees, and refrigerant, with no package number hiding the margin. We pull permits through the Lexington-Fayette Urban County Government where required, because unpermitted work can void a homeowner’s insurance and surface as a problem at sale. And when a system can be repaired, we say so, even when replacement would pay us more. We would rather have the call next winter than the one big sale today. When a true emergency hits — a no-heat night, a dead condenser in a heat advisory — our line is answered 24/7, and we give you an honest arrival window rather than a number we can’t hit.

Frequently Asked Questions

Who owns Lexington Heating and Air?: William Gamino owns and operates Lexington Heating and Air, which he founded in 2015. The company works from its shop at 343 Cassidy Ave in Lexington and serves residential and commercial customers across Fayette County rather than operating as a large regional chain. William holds a Kentucky HVAC contractor license and EPA Section 608 certification and still runs service calls himself.
Why does HVAC equipment perform differently in central Kentucky?: Two measurable factors drive it. First, Lexington’s humid summers pair high heat with dew points in the upper 60s and low 70s, creating a heavy latent cooling load — so equipment has to be selected for moisture removal, not just temperature, or it short-cycles and leaves the house cool but clammy. Second, the Bluegrass region’s Ordovician limestone produces hard municipal water that scales humidifiers and clogs condensate drains faster than manufacturer ratings assume. Equipment selection and service intervals both have to account for these.
What areas does Lexington Heating and Air serve?: The company serves all of Lexington and Fayette County, including neighborhoods such as Ashland Park, Chevy Chase, Kenwick, Hamburg, and Andover, along with the nearby communities of Nicholasville, Versailles, Georgetown, Wilmore, and Midway. The Cassidy Ave location keeps response times short across most of central Lexington.
Is the company licensed and insured?: Yes. Lexington Heating and Air operates under Kentucky HVAC Contractor License #HM04788 through the Department of Housing, Buildings and Construction, with EPA Section 608 Universal certification covering R-22, R-410A, and R-454B. The company carries general liability and workers’ compensation coverage, employs NATE-certified technicians, and pulls permits through the LFUCG Division of Building Inspection where required.
Does William still do the work himself?: Yes. Unlike larger outfits where the owner is purely administrative, William remains directly involved in service and installation work across Fayette County. When he recommends a repair over a replacement, or one system over another, it comes from someone who is still on the tools and accountable for the outcome.
