These are absolutely the most efficient, professional, courteous workers that have ever been in my home. I would totally recommend these men to anyone. They were so concerned with our family's needs of comfort and even placed plastic down to walk on. They were so neat that I did not even need to vacuum afterwards. Very satisfied!!

How this is calculated ▾
Baseline propane usage for a mid-KY winter comes from the ~2,500 heating-degree-day climate of Laurel County. Insulation and setpoint apply straightforward multipliers (roughly 3% per degree, 22–32% swing between drafty and tight envelopes).
Propane furnace: baseline gallons × your $/gal price, 90% AFUE mid-market gas furnace. Electric strips: same BTU load at 1 kWh = 3,412 BTU, priced at your electric rate. Cold-climate heat pump: HSPF2 ≈ 8.5 — roughly 2.5× COP over a KY heating season. Dual-fuel: heat pump above ~30°F (about 65% of the season), propane below — weighted 65/35.
Your actual winter cost depends on solar exposure, air infiltration, ductwork, and how often the door opens.

What Should This Cost?
Pick the service you're weighing — see a typical industry price range for reference, what drives it up or down, and what a PMA member would save. These are not our quotes: your written estimate is free, comes from a no-pressure on-site visit, and may differ.
Service estimate builder
Repair · Typical industry range (reference only)
$79–$149
30–60 min on site PMA members save 10% on repairs
We diagnose the problem and tell you what's wrong before we quote the repair — no repair work starts without your OK.
What moves the number
- Standard hours vs. after-hours (until 10 PM)
- Distance from London, KY
- Weekend / holiday visits
Maintenance · Typical industry range (reference only)
$109–$199
1–2 hours per system Included twice yearly with a Preventive Maintenance Agreement
A full seasonal checkup — the appointment most homeowners forget until something breaks. Cheaper than an emergency call, every year.
What moves the number
- Single system (AC or heat) vs. combo package
- Two systems in one home (e.g. upstairs / downstairs)
- Age of equipment — older systems need more time
Repair · Typical industry range (reference only)
$150–$850
1–3 hours on site (parts permitting) 10% off parts + labor for PMA members
Covers the vast majority of AC calls — capacitors, contactors, motors, refrigerant, sensors. Major component replacements (compressor, evaporator coil) run higher and we quote before we start.
What moves the number
- Component failure (capacitor $150–350 · motor $400–800 · coil $900+)
- Refrigerant type (R-410A is standard; R-22 systems cost more)
- Age of system — some 15+ yr parts are hard to find
- Warranty status on the part
Repair · Typical industry range (reference only)
$175–$950
1–3 hours on site (parts permitting) 10% off parts + labor for PMA members
Igniters, flame sensors, gas valves, blower motors, heat exchangers — most heating failures fall in this range. If we find a cracked heat exchanger we'll show you the CO risk before recommending anything.
What moves the number
- Fuel type (natural gas · propane · electric · dual-fuel heat pump)
- Component failure (igniter $200–350 · gas valve $400–700 · blower $500–900)
- AFUE efficiency of the existing furnace
- Whether the fault is safety-critical (we won't leave a CO risk running)
New System · Typical industry range (reference only)
$4,800–$9,500
Financing available for qualified homeowners (industry reference: roughly $95–$185/mo — not an offer)
1 day install (most homes) A PMA keeps factory warranty requirements current
Includes the outdoor condenser, matched indoor coil, refrigerant charge, and standard connections. Professionally installed by factory-trained technicians — manufacturer warranties apply.
What moves the number
- Tonnage: 2 ton (small home) · 3 ton (mid) · 4–5 ton (large / dual-zone)
- SEER2 efficiency rating (14.3 baseline vs 17+ variable-speed)
- Existing ductwork condition and coil compatibility
- Electrical service, pad / pad prep, refrigerant line changes
New System · Typical industry range (reference only)
$3,600–$8,200
Financing available for qualified homeowners (industry reference: roughly $75–$160/mo — not an offer)
1 day install (most homes) A PMA keeps factory warranty requirements current
Gas, propane, or electric — matched to your home's heat load, ductwork, and how you actually live. We install the full range, from builder-grade to high-efficiency modulating, matched to the job.
What moves the number
- Fuel type (natural gas · propane · electric)
- AFUE efficiency (80% builder-grade vs 96%+ high-efficiency)
- BTU input matched to actual heat load, not square footage guessing
- Ductwork / venting modifications (side-wall vent, PVC for condensing furnaces)
New System · Typical industry range (reference only)
$6,800–$12,500
Financing available for qualified homeowners (industry reference: roughly $135–$245/mo — not an offer)
1–2 days install A PMA keeps factory warranty requirements current
One system, both heating and cooling — the right call for Laurel County's mixed climate when paired with propane or electric backup heat. Ask about current rebates and financing.
What moves the number
- SEER2 + HSPF2 rating (higher efficiency tier — ask about current rebates)
- Backup heat strategy (electric strips vs dual-fuel with furnace)
- Home size + insulation quality (drives load calc)
- Existing pad, disconnect, and electrical service capacity
Duct Work · Typical industry range (reference only)
$1,800–$6,500
1–3 days on site
Custom sheet-metal fabrication in-house — we don't sub it out. Full replacements or targeted fixes (a bad trunk, a leaky return, a room that never gets warm).
What moves the number
- Linear feet of new duct + number of registers / returns
- Sheet metal (higher static pressure, longer life) vs. flex
- Attic vs. crawlspace access — accessibility drives labor
- Zoning, dampers, or fresh-air integration
Commercial · Typical industry range (reference only)
$3,500–$22,000
Custom quote — usually 2–5 days on site
Rooftop package units, split systems, controls integration, and specialty applications. 75+ years of commercial designs across Laurel County — restaurants, offices, retail.
What moves the number
- Rooftop unit vs. split system architecture
- BTU load (from actual heat-load calc, not sq ft)
- Roof access (crane vs. lift vs. hand-hoist)
- Controls / BMS integration, economizers, gas hookup
Ranges are typical industry figures shown for reference only — not a quote and not Leo Jones & Son pricing. Your written estimate is free, comes from an on-site Comfort Consultant visit, and may differ. Emergency service available until 10 PM.

All Service Areas →Repair or Replace?
A Straight Answer, Not a Sales Pitch
Answer three questions — get an honest recommendation using the industry's $5,000 Rule. If replacement is genuinely the better call, we'll tell you. If a repair makes sense, we'll say that too.
Repair or replace decision tool
Our recommendation
Repair — this one's worth it
The math
7 yrs × $750 = 5,250
Rule of thumb: score under $2,000 = repair, $2,000–$5,000 = consider replacement, over $5,000 = replace.
Under 10 years old with a mid-range repair estimate — this system has plenty of life left. The math strongly favors fixing the current issue.
Straight answer, not a sales pitch — if repair is the right call, we'll say so.
