Top 7 HVAC companies in Monmouth, New Jersey

Monmouth County sits in IECC zone 4A with 4800 heating degree days and 1200 cooling degree days. Natural gas remains the dominant heating fuel while central air saturation is already high. Homeowners replacing equipment therefore face a heating-leaning mixed load that rewards correct sizing and proper refrigerant charge. Public listing data collected August 16, 2026 supplies the only evidence used here. No site visits or interviews occurred.

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.

High Ground Service Pros

High Ground Service Pros operates from 2150 NJ-88, Brick Township, NJ 08724 and lists the phone number (732) 338-0626. Its 111 reviews produced a raw rating of 5 that the Bayesian step adjusted downward to 4.95; two tie-breakers then lifted the final score to 5.01. The firm appears as a general contractor yet publishes a website and 24/7 availability. Those signals placed it first. The numbers cannot reveal whether the 111 reviews cover only HVAC work or also other contracting tasks.

Air Care

Air Care lists 113 reviews at a raw 5 that adjusted to 4.95 before a single tie-breaker for its public website produced the final 4.99. The address is 608 Monmouth Ave, Bradley Beach, NJ 07720 and the contact number is (732) 988-0151. It is carried as a general contractor without published 24/7 hours. Its large review count kept the Bayesian pull modest. The data leave open whether the firm’s workload is primarily residential or includes light commercial jobs.

California Coolers

California Coolers recorded 53 reviews at raw 5, adjusted to 4.915, then rose to 4.975 after website and 24/7 tie-breakers. The address 12 Deal Ave, Oceanport, NJ 07757 pairs with phone (732) 610-1126. Listed only as a general contractor, the firm still shows both website and round-the-clock availability. Its smaller review total allowed greater movement from the tie-breakers. Nothing in the listing confirms how many of the 53 reviews addressed cooling versus heating work.

D & R Heating & Air Conditioning

D & R Heating & Air Conditioning holds 65 reviews at raw 5, adjusted to 4.925, then to 4.965 after the website tie-breaker. Street address is 173 Windham Way, Freehold, NJ 07728; phone is (732) 904-8072. It appears as a general contractor without 24/7 listing. The review volume limited the Bayesian shift. The listing supplies no breakdown of service calls versus installations.

Coast LLC

Coast LLC shows 43 reviews at raw 5, adjusted to 4.903, then 4.923 after the 24/7 tie-breaker alone. Address 708 NJ-35, Neptune City, NJ 07753 matches phone (732) 775-9131. No website is listed and the category remains general contractor. Its review count permitted a noticeable tie-breaker lift. The numbers do not indicate how many of the 43 reviews came from emergency calls.

Port Monmouth Heating & Air Conditioning

Port Monmouth Heating & Air Conditioning posted 10 reviews at raw 4.9 with no tie-breakers, so adjusted score stayed at 4.798. Address 21 Mills Ave, Port Monmouth, NJ 07758 pairs with (732) 931-7727. It is listed as a general contractor without website or 24/7 hours. The small review count produced almost no Bayesian movement. Ten reviews leave open whether performance has been consistent across seasons.

Advanced Air Services, LLC

Advanced Air Services, LLC recorded 17 reviews at raw 4.5, adjusted to 4.669 with no tie-breakers applied. Address 24 Redwood Dr, Eatontown, NJ 07724 matches phone (732) 687-7294. Listed only as a general contractor, it shows neither website nor 24/7 availability. Its below-mean raw rating moved upward only slightly under the Bayesian formula. Seventeen reviews cannot yet demonstrate whether recent work matches earlier results.

Selecting a contractor

Review volume, adjusted rating, and the presence of a public website or 24/7 listing determine placement. All seven firms are carried as general contractors rather than HVAC specialists. Homeowners must separately verify both the Master HVACR Contractor license and Home Improvement Contractor registration before signing any agreement.

Installed costs

One data source places typical full-system installation between $10,600 and $13,000 while 2025 invoiced averages reached $19,579 with the upper quartile at $28,932. Labor is billed at $150 per hour and permit fees run $175–$600. The two cost sources diverge because one reflects planned budgets and the other reflects actual billed amounts in the county. Both figures sit in the high tier versus national averages.

Local climate demands

Monmouth County falls in IECC zone 4A with a moist regime. Winter design temperature is 13 °F and summer design reaches 92 °F under humid conditions. The load profile is heating-leaning mixed, supported by 4800 heating degree days against 1200 cooling degree days. Dense natural-gas infrastructure exists, yet heat-pump suitability remains very good. Equipment must handle balanced but heating-dominant loads and humidity control during shoulder seasons. Proper sizing is critical because oversizing reduces dehumidification capacity in summer.

Licensing and permits

New Jersey maintains statewide HVACR contractor licensure through the New Jersey State Board of Examiners of Heating, Ventilating, Air Conditioning and Refrigeration Contractors — Division of Consumer Affairs. A Master HVACR Contractor license is required; a limited license is also issued for narrower scopes. Minimum $500,000 general liability insurance from a New Jersey-licensed insurer plus workers’ compensation coverage is mandatory. HVACR licensure has been uniform statewide since 2014, allowing a licensed contractor to work anywhere in the state. Mechanical permits for furnace or AC changeouts, however, are issued by each local municipal construction office and fees vary by jurisdiction.

Available incentives

The M-RISE / Community Partners HEAR program under NJBPU is conditionally approved with a planned $8,000 heat-pump rebate that stacks with NJCEP incentives. Utility rebates through PSE&G, JCP&L and others range from $1,000 to $4,000. No state tax credit exists. Federal 25C and 25D credits expired at the end of 2025; only the commercial 48E ITC survives for 2026 under strict timing rules. NJCEP participation is required for access to ratepayer rebates, so homeowners should first confirm which listed firms hold that status before requesting quotes.

Public data alone cannot confirm workmanship quality or current licensing status on any given date. Verify both the HVACR license and Home Improvement Contractor registration directly with the Division of Consumer Affairs before engaging any contractor.
