Top 7 HVAC companies in Jefferson, Kentucky

Jefferson County sits in a mixed-humid climate that produces roughly 4,200 heating degree days against 1,400 cooling degree days. Natural gas remains the dominant heating fuel, yet heat-pump suitability is rated very good. The seven contractors below are ordered by a Bayesian-adjusted rating that tempers small-sample scores toward the national mean of 4.764. This shortlist is built from public listing data, not a review of work performed.

The shortlist

Jefferson HVAC Solutions Heating & Air Conditioning

Jefferson HVAC Solutions Heating & Air Conditioning operates from 492 Brooksville-Germantown Rd, Brooksville, KY 41004 as a general contractor without published 24/7 hours. Its raw 5.0 rating from 60 reviews drops to an adjusted 4.961 because the Bayesian pull toward 4.764 is still noticeable at this review depth. The firm maintains a public website, which supplied one of the tie-breaker signals. These numbers cannot reveal whether the six dozen reviews cluster around recent jobs or older work.

UR Best HVAC

UR Best HVAC lists 157 reviews at a raw 4.9 that adjusts downward only to 4.938. The address is 405 Lakeview Trail, Shepherdsville, KY 40165 and the phone is (502) 851-4039. Its general-contractor listing plus published 24/7 availability both contributed to ranking position. The modest 0.038-point adjustment reflects the larger review count already anchoring the score near the observed rating.

ProTech Heating and Air

ProTech Heating and Air posts 112 reviews at raw 4.9, adjusted to 4.931. The street address is 437 Big Hill Ave, Richmond, KY 40475 and the phone is (859) 353-5429. General-contractor status and 24/7 availability again supplied tie-breakers. With more than one hundred reviews the score moves only 0.031 points toward the national mean.

C & L Heating and Air

C & L Heating and Air records the largest sample at 300 reviews, raw 4.9 adjusted to 4.928. Address: 16321 Dry Ridge Rd, Louisville, KY 40299. Phone: (502) 969-7016. The general-contractor category is the only signal listed. Three hundred reviews keep the adjustment small at 0.028 points, demonstrating how volume stabilizes the rating.

Jefferson Heating & Air Inc.

Jefferson Heating & Air Inc. shows 78 reviews, raw 4.9 adjusted to 4.902. The address is 5041 US-68, Maysville, KY 41056 and the phone is (606) 759-7030. A public website is the sole extra signal. The 0.038-point drop from raw to adjusted score follows from a review count that still allows noticeable mean reversion.

Airtech Heating and Cooling Services LLC

Airtech Heating and Cooling Services LLC carries 160 reviews at raw 4.8, adjusted to 4.834. Address: 9462 Brownsboro Rd #288, Louisville, KY 40241. Phone: (502) 289-1686. The general-contractor listing supplies the only ranking signal. The 0.034-point adjustment is modest given the sample size above 150.

Louisville Mechanical Services

Louisville Mechanical Services lists 41 reviews at raw 4.6 adjusted upward to 4.729. Address: 11121 Plantside Dr, Louisville, KY 40299. Phone: (502) 962-9211. General-contractor status and 24/7 availability both appear. The 0.129-point lift occurs because the smaller sample allows stronger movement toward the 4.764 mean.

How to choose

Verify every contractor through the Kentucky DHBC licensee search before requesting quotes. Compare recent review volume rather than headline star ratings, and confirm the firm pulls mechanical permits from the correct local jurisdiction. Ask whether the installer participates in any utility rebate networks that may affect equipment choices.

Cost

One dataset places a typical full-system install between $7,600 and $9,300. A second source reports an invoiced average of $17,632 with the upper quartile at $23,825. The divergence itself signals that project scope, equipment tier, and contractor overhead vary widely. Labor is published at $90 per hour and local permit fees range from $90 to $300. Both cost sources are retained because neither can be dismissed on the data given.

Climate

Jefferson County falls in IECC zone 4A with a moist regime. Winter design temperature is 12 °F and summer design reaches 93 °F under humid conditions. Heating loads dominate at 4,200 degree days against 1,400 cooling degree days, producing a heating-leaning mixed profile. Equipment must handle both deep winter heating and high summer latent loads, which favors properly sized heat pumps or dual-fuel systems.

Licensing and permits

HVAC licensing is issued at state level by the Kentucky Department of Housing, Buildings and Construction — Division of Heating, Ventilation and Air Conditioning. The required credential is Master HVAC Contractor. The state mandates $500,000 general liability and $300,000 property-damage insurance plus workers-compensation coverage for firms with one or more employees. Mechanical permits for furnace or AC replacements are pulled locally from city or county building departments rather than from the state.

Incentives

Kentucky Home Energy Rebates remain conditionally approved with no launch date and a planned $8,000 heat-pump maximum. No state tax credit exists. Utility programs through LG&E/KU and TVA offer $100 to $1,500 rebates, yet TVA territory requires QCN contractor membership. Federal 25C and 25D credits expired at the end of 2025, leaving only the commercial 48E ITC. Homeowners should therefore prioritize installers already inside utility networks to capture available rebates.
