Top 7 HVAC companies in Westmoreland, Pennsylvania

Westmoreland County sits in Pennsylvania climate zone 5A with 5,400 heating degree days and only 1,000 cooling degree days. The heating load dominates equipment choice and sizing calculations. Winter design temperature is 15 degrees Fahrenheit while summer design reaches 92 degrees Fahrenheit with humid conditions. Natural gas remains the primary heating fuel and central air conditioning saturation is already high. Heat pumps are rated good with backup heat. Peak service demand occurs in winter. Internal county variation runs from zone 4A near Philadelphia to 6A in the northern tier, so equipment must handle wide temperature swings and contractors must size for the actual micro-climate rather than county averages.

Climate in Westmoreland County

Westmoreland County experiences a heating-dominant mixed load profile. The 5,400 heating degree days dwarf the 1,000 cooling degree days, so furnaces and boilers run far more hours than air conditioners. Design temperatures of 15 degrees Fahrenheit in winter and 92 degrees Fahrenheit in summer set the equipment capacity targets. Humidity stays high in summer and low in winter, which affects latent load calculations and dehumidification needs. Natural gas supplies most existing heating systems and central air conditioning penetration is already high. Heat pumps receive a suitability rating of good with backup, reflecting the cold snaps that push below efficient heat-pump range. Peak service season falls in winter. The engineering note highlights wide internal variation across zones 4A to 6A, requiring installers to verify local design conditions rather than apply a single county template.

The shortlist

Companies are ranked by a Bayesian-adjusted rating: a company's star rating is pulled toward the national mean of 4.764 until it has enough reviews to stand on its own. This is a shortlist built from public listing data, not a review of work performed.

Montell's HVAC

Montell's HVAC operates from 627 Rosensteel Ln, Greensburg, PA 15601 and lists the phone number (724) 757-2261. Its listing shows a general-contractor category without published 24/7 availability. The raw rating of 5.0 rests on 21 reviews and the Bayesian adjustment lowered it to 4.861 because the modest review count still exerts pull toward the national mean of 4.764. These numbers cannot reveal whether the firm carries the proper municipal mechanical permits or maintains current insurance certificates on file with carriers.

Heirloom Mechanical

Heirloom Mechanical lists 213 Elm Dr, Mt Pleasant, PA 15666 and the phone number (412) 889-6800. Its general-contractor category includes published 24/7 availability. Twelve reviews produced a raw 5.0 that the adjustment lowered to 4.831. The tie-breakers for a public website and 24/7 listing improved its position relative to firms without those signals. The figures give no information on whether recent jobs met local code enforcement standards or how the firm handles parts availability during peak winter demand.

Westmoreland Heating & Cooling

Westmoreland Heating & Cooling is located at 208 W 3rd St, Greensburg, PA 15601 with phone (724) 539-4549. The general-contractor listing includes 24/7 availability. Seventeen reviews at 4.8 produced an adjusted score of 4.777 after modest upward movement toward the national mean. Both website and 24/7 signals contributed to its rank. The data set supplies no detail on technician training records or the frequency of callback rates after installations.

Finest Air Solutions

Finest Air Solutions lists 2303 Ligonier St, Latrobe, PA 15650 and the phone number (724) 972-6002. Its general-contractor category shows 24/7 availability without a public website. Eight reviews at a raw 5.0 yielded an adjusted rating of 4.814. The 24/7 tie-breaker alone placed it ahead of some higher-review firms. These counts cannot indicate whether the firm maintains EPA 608 records or carries current liability coverage meeting municipal minimums.

Keystone Refrigeration

Keystone Refrigeration operates from 742 Spring St, Latrobe, PA 15650 with phone (724) 537-5093. The services category carries no 24/7 claim. Thirty reviews at 4.9 produced an adjusted score of 4.832 after slight downward movement toward the national mean. No tie-breakers applied. The larger review volume gives the adjusted rating more stability than smaller samples, yet the numbers still omit any record of municipal permit compliance history.

Limbach Company LLC

Limbach Company LLC lists 1139 Broad St, Greensburg, PA 15601 and the phone number (412) 359-2118. Its general-contractor entry includes both a public website and 24/7 availability. One review at a raw 5.0 produced an adjusted rating of 4.772 after noticeable pull toward the national mean. The two tie-breakers kept it from falling further. A single review supplies almost no statistical weight, leaving open questions about consistency across jobs of different sizes.

Gene Salvio Heating & Air Conditioning

Gene Salvio Heating & Air Conditioning is at 303 8th Ave, Sutersville, PA 15083 with phone (724) 872-5373. The general-contractor listing shows 24/7 availability without a website. Fifteen reviews at 4.6 produced an adjusted score of 4.709 after upward movement toward the national mean. The 24/7 tie-breaker improved its final placement. The modest review count leaves open whether winter service response times match the published availability claim.

How to choose an HVAC contractor

Verify Home Improvement Contractor registration directly with the Pennsylvania Attorney General before any discussion of scope. Request current certificates of general liability and automobile insurance from the issuing carrier rather than accepting copies from the contractor. Confirm EPA 608 certification for refrigerant handling. Ask the municipality where the work will occur which mechanical permit class applies and whether the contractor is pre-qualified to pull it. Compare the number of recent reviews against the adjusted rating to gauge statistical stability. Treat 24/7 claims as scheduling signals only, not guarantees of same-day response during peak winter loads.

Cost of HVAC work

Modeled typical full-system installation sits at $10,200 with a published range of $9,200 to $11,200. The 2025 invoiced average reached $19,990 while the upper quartile hit $28,500. Labor is stated at $120 per hour and permit fees range from $100 to $400. The two cost sources diverge sharply: the invoiced average is roughly twice the modeled typical price. Both sources are retained because each reflects different project scopes and market segments. No single figure should be treated as a fixed bid; actual pricing depends on equipment efficiency, duct modifications, and the specific municipality's permit process.

Licensing and permits

Pennsylvania has no state HVAC contractor licensing board. Licensing and mechanical permitting occur at the municipal level under the statewide Uniform Construction Code. Philadelphia issues a Mechanical Contractor License plus Sheet Metal and Heating Equipment Installer licenses through its Department of Licenses and Inspections. Pittsburgh maintains its own local program. Elsewhere, including Westmoreland County, individual towns enforce requirements. Home Improvement Contractor registration with the Pennsylvania Attorney General is mandatory for residential work exceeding $5,000 annually and requires a $50,000 bond. Insurance minimums vary by jurisdiction; Philadelphia, for example, requires $500,000 general liability and $300,000 automobile liability plus workers' compensation in some cases. Always confirm the current municipal permit authority before signing a contract.

Incentives in 2026

Penn Energy Savers remains conditionally approved with a planned launch at the end of 2025 or early 2026 and a maximum heat-pump rebate of $8,000. No state tax credit applies. Act 129 utility programs from PPL, PECO, Duquesne Light, FirstEnergy subsidiaries, UGI, PGW, and Peoples Gas offer rebates between $200 and $1,000, but only through participating contractors. The federal 25C and 25D credits expired 31 December 2025. The 48E investment tax credit survives only for commercial or third-party-owned systems meeting begin-construction or placed-in-service deadlines. Because Pennsylvania lacks any statewide HVAC license, homeowners must verify Home Improvement Contractor registration, direct insurance confirmation, and EPA 608 certification before discussing any rebate-eligible equipment. Utility network participation further narrows the installer pool for incentive claims.
