Top 7 HVAC companies in Westchester, New York

Cost of HVAC work in Westchester

Installed-cost figures for a full residential system in Westchester diverge. One dataset places the typical price at $12,450 with a range of $11,200 to $13,700. A second source reports an invoiced average of $15,721 and an upper-quartile figure of $22,000. Labor is listed at $160 per hour. Permit fees range from $200 to $700. Both sources are cited because the spread itself is the usable information for budgeting.

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.

Westchester Heating & Cooling

Westchester Heating & Cooling operates from 282 Katonah Ave Ste 157, Katonah, NY 10536 and lists the phone number (914) 205-4757. Its 41 reviews produced a raw rating of 5 that the adjustment lowered to 4.94 because the national mean sits at 4.764; the large review count limited the pull. The firm appears as a general contractor without 24/7 listing, yet the volume of feedback still placed it first. These numbers say nothing about how the company handles change-order pricing or callback response on a given job.

All County Heating & Air Conditioning

All County Heating & Air Conditioning lists the phone number (914) 271-8380 at 3 Birch Ct, Croton-On-Hudson, NY 10520. Its five reviews at raw 5.0 adjusted downward only to 4.858, still above the national mean, aided by both a public website and published 24/7 availability. The general-contractor listing and small sample leave open the question of how the firm performs on larger retrofits.

Atlantic Westchester, Inc.

Atlantic Westchester, Inc. can be reached at (914) 666-2268 from 264 Adams St, Bedford Hills, NY 10507. Three reviews at raw 5.0 moved to 4.845 after adjustment, the 24/7 listing and website supplying the tie-breaker margin. The general-contractor category and limited review depth mean the numbers cannot address equipment-brand preferences or post-install service intervals.

Conscious Mechanical

Conscious Mechanical lists the phone number (914) 426-8545 at 7 Legion Dr, Valhalla, NY 10595. Eight reviews at raw 5.0 adjusted to 4.834; 24/7 availability provided the ranking signal even without a public website. The general-contractor designation leaves unclear whether the firm maintains specialized tooling for hydronic retrofits common in the county.

Westchester HVAC

Westchester HVAC lists the phone number (914) 730-5631 at 465 Tuckahoe Rd, Yonkers, NY 10710. Its three reviews at raw 5.0 adjusted to 4.805, again helped by 24/7 availability. The absence of a website and the general-contractor listing mean the figures give no indication of how the firm documents load calculations.

Alex

Alex lists the phone number (914) 637-0077 at 445 Fifth Ave, Pelham, NY 10803. Thirty-seven reviews produced a raw rating of 4.7 that the adjustment raised to 4.789 because the score sat below the national mean; the website and 24/7 listing supplied additional lift. The general-contractor category and moderate review count leave open how the firm manages peak winter demand.

HHVAC Indoor Technologies LLC

HHVAC Indoor Technologies LLC lists the phone number (914) 787-9772 at 3003 Purchase St #91, Purchase, NY 10577. Twenty-one reviews at raw 4.4 adjusted upward to 4.674; the website and 24/7 listing kept the firm on the list despite the larger distance from the national mean. The general-contractor listing means the numbers cannot reveal typical equipment brands stocked.

Licensing and permits in Westchester

New York maintains no statewide HVAC contractor licensing board. Authority is delegated to cities and counties, so requirements differ between, for example, New York City and the separate Westchester towns. The New York City Department of Buildings issues Oil Burner Equipment Installer licenses for oil-fired equipment and, depending on system type, may require a High-Pressure Boiler Operating Engineer or Special Rigger license. Electric-only central air or heat-pump work falls under general contractor and permit rules without a dedicated trade license. Insurance minimums are set locally; New York City requires General Liability, Workers' Compensation and Disability coverage for oil-burner licensees, yet no uniform statewide dollar threshold exists for general HVAC work. Permits themselves are issued at the municipal level, not by the state. Homeowners must contact the building department of the specific town or village where the work will occur to confirm current licensing and permit obligations.

Climate demands on HVAC systems

Westchester sits primarily in IECC zone 5A, a moist heating-leaning mixed climate with 5,700 heating degree days and only 900 cooling degree days. Winter design temperature reaches 15 °F while summer design reaches 91 °F with humid conditions. The load profile favors heating, and primary fuels remain natural gas and fuel oil. Central-air saturation is moderate to high, yet the engineering note highlights a large existing steam and hydronic retrofit market. Equipment therefore needs cold-climate heat-pump capability or robust backup, and proper sizing must account for the county's older housing stock rather than simple rule-of-thumb tonnage.

Available incentives in 2026

NYS Clean Heat and EmPower+ / NY Home Energy Rebates remain the active programs, though availability is limited. Heat-pump rebates reach $8,000 under HEAR and up to $10,000 for income-eligible households through EmPower+. The state tax credit applies only to solar equipment. Utility rebates range from $1,000 to $5,000 through Con Edison and other major providers, but payment flows through a participating contractor; non-network installers cannot deliver the incentive. Federal 25C and 25D credits expired at the end of 2025. Only the commercial 48E ITC survives under narrow conditions. Homeowners must therefore confirm network status before obtaining quotes.

How to choose an installer

Compare the Bayesian-adjusted score and review count first, then verify NYS Clean Heat participation to preserve rebate eligibility. Confirm the exact permit and insurance rules that apply in the town where the equipment will be installed, because licensing is local. Request load calculations rather than rule-of-thumb sizing given the county's heating-dominant profile and older housing stock.
