Top 7 HVAC companies in Somerset, New Jersey

Public listing data for Somerset County shows a market with modest review volume and several general contractors offering HVAC work. The ranking applies a Bayesian adjustment that pulls every raw rating toward the national mean of 4.764. Companies with very few reviews therefore sit closer to that mean than their raw scores suggest. Installed costs sit above national averages and 2026 incentives carry strict contractor-network rules.

Cost data for Somerset County

Installed costs in Somerset County display a clear split between sources. One dataset lists a typical full-system price of $11,800 inside a $10,600 to $13,000 band. A second 2025 invoice sample reports an average of $19,579 with the upper quartile reaching $28,932. Labor is recorded at $150 per hour. Permit fees range from $175 to $600 and are collected by the local municipality rather than the state. The two cost sources disagree by several thousand dollars on the central tendency; both figures are therefore presented without reconciliation.

The shortlist

Companies are ranked by a Bayesian-adjusted rating: a company's star rating is pulled toward the national mean until it has enough reviews to stand on its own, so a 5.0 from four customers does not outrank a 4.9 from two hundred. Small tie-breakers apply for a public website, for being listed as an HVAC specialist rather than a general contractor, and for published 24/7 availability. This is a shortlist built from public listing data, not a review of work performed.

Nastus Brothers Inc.

Nastus Brothers Inc. operates from 320 Ward St, New Brunswick, NJ 08901 and lists the phone number (732) 246-3887. Its listing appears under the general-contractor category while advertising 24/7 availability. The firm posted a raw rating of 5 from 7 reviews. That raw score sits 0.236 above the national mean of 4.764; the Bayesian adjustment lowers the score to 4.829 because the modest review count still exerts pull toward the mean. The published 24/7 signal supplied the final tie-breaker that secured first place. These numbers do not reveal whether the firm maintains current insurance or carries the required dual registrations.

Air Comfort Technology, LLC

Air Comfort Technology, LLC lists the address 20 Freeman Rd, Somerset, NJ 08873 and the phone number (732) 287-1229. Its category is recorded as Services and it advertises 24/7 availability. No reviews appear in the data, producing a raw rating of 0. The Bayesian adjustment therefore lifts the score from 0 to 4.824, moving it 0.06 above the national mean of 4.764. A public website and 24/7 listing supplied the tie-breakers that placed the firm second. The absence of reviews leaves open every question about actual field performance.

Air Control Mechanical Contracting

Air Control Mechanical Contracting gives the address Somerset, NJ 08873 and the phone number (732) 627-0033. The listing falls under general contractor and shows a public website but no 24/7 claim. Two reviews yield a raw rating of 5. The adjustment pulls that score down 0.181 to 4.819 because the small sample size still tethers the result to the national mean of 4.764. The website alone provided the tie-breaker for third position. The figures supply no information on whether the two reviewers represent typical jobs or edge cases.

Yeshire Mechanical LLC

Yeshire Mechanical LLC operates from 60 Douglas Ave, Somerset, NJ 08873 and lists the phone number (732) 484-6869. Its category is general contractor and it maintains a public website. Two reviews again produce a raw rating of 5. The Bayesian step lowers the score 0.181 to 4.819 for the same reason given above. The website tie-breaker fixed fourth place. Nothing in the numbers indicates how recently those two reviews were left or whether the projects matched the work now under consideration.

Heating & Cooling

Heating & Cooling lists the address 200 Cottontail Ln, Somerset, NJ 08873. Its category is general contractor and it advertises 24/7 availability, yet the listing contains no phone number. Four reviews produce a raw rating of 5. The adjustment reduces that score 0.188 to 4.812 because the review count remains low relative to the national mean of 4.764. The 24/7 signal supplied the tie-breaker for fifth place. The missing phone number prevents direct contact from the published data alone.

Somerset Heating and Cooling Services LLC

Somerset Heating and Cooling Services LLC gives the address 13 Clyde Rd Ste 201, Somerset, NJ 08873 and the phone number (732) 595-7734. The listing is under general contractor and shows 24/7 availability. Seven reviews yield a raw rating of 4.4. That raw score sits 0.364 below the national mean of 4.764; the Bayesian adjustment therefore raises the score 0.315 to 4.715. The 24/7 signal fixed sixth place. The modest review count still leaves open whether the 4.4 average reflects recent or older work.

Unitemp Inc.

Unitemp Inc. lists the address 26 Worlds Fair Dr C, Somerset, NJ 08873 and the phone number (908) 753-4800. Its category is general contractor and it maintains a public website. Three reviews produce a raw rating of 2.3. That raw score sits 2.464 below the national mean of 4.764; the Bayesian adjustment therefore raises the score 2.28 to 4.58. The website tie-breaker placed the firm seventh. The low review count and low raw rating together mean the adjusted score still rests on very limited evidence.

Licensing and permits

New Jersey maintains a state-level licensing regime through the New Jersey State Board of Examiners of Heating, Ventilating, Air Conditioning and Refrigeration (HVACR) Contractors — Division of Consumer Affairs. The board issues a Master HVACR Contractor license; a limited license restricting scope to specific system types is also available. Minimum insurance requirements include $500,000 in general liability coverage from a New Jersey-licensed insurer plus workers compensation coverage under N.J.S.A. 45:16A. HVACR contractor licensure has been uniform statewide since 2014, allowing a licensed contractor to work anywhere in the state. Mechanical permits for residential furnace or AC changeouts are issued by the local municipal construction or code-enforcement office, not by the state board. Home Improvement Contractor registration with the Division of Consumer Affairs is also required for residential work even though it is separate from the HVACR license.

Climate demands in Somerset County

Somerset County falls in IECC zone 4A with a moist regime. Heating degree days total 4,800 while cooling degree days reach only 1,200, producing a heating-leaning mixed load profile. Newark design temperatures are 13 °F in winter and 92 °F in summer, with humid summers. Natural gas remains the primary heating fuel, yet heat-pump suitability is rated very good and central-air saturation is already high. Peak service demand occurs in summer. The balanced loads and dense gas infrastructure mean equipment must handle both heating and cooling seasons without oversizing; the engineering note highlights that strong heat-pump incentive programs exist alongside the existing gas network.

Incentives available in 2026

The state program M-RISE / Community Partners HEAR under NJBPU is listed as conditionally approved, with a planned maximum heat-pump rebate of $8,000 that can stack with NJCEP offerings. No state tax credit applies. Ratepayer programs run through the New Jersey Clean Energy Program include Comfort Partners and Whole House Energy Solutions, offering utility rebates between $1,000 and $4,000. Major utilities include PSE&G, JCP&L, Atlantic City Electric, Rockland Electric, NJ Natural Gas and South Jersey Gas. All NJCEP rebates require use of a participating contractor. Federal 25C and 25D residential tax credits expired at the end of 2025, leaving no federal HVAC tax credit for 2026; the 48E ITC survives only for commercial or third-party-owned systems. These rules mean a homeowner must verify both HVACR licensure and NJCEP network status before any rebate discussion begins.

How to choose an installer

NJ requires BOTH an HVACR contractor license and Home Improvement Contractor registration; many installers hold only one. Because rebates are explicitly stackable, the installer must appear on the NJCEP participating-contractor list to unlock the full incentive stack. Verify both credentials through the board lookup at newjersey.mylicense.com/verification and confirm current NJCEP status before requesting quotes.

Public data alone cannot confirm workmanship, current insurance status or recent complaint history for any firm on the list.
