Top 7 HVAC companies in Suffolk, New York

Cost of HVAC work in Suffolk County

Installed costs in Suffolk County sit above national averages. One data source lists a typical full-system price of $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 stated at $160 per hour. Permit fees run from $200 to $700. The two sources disagree on the central tendency, and that spread itself is useful 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.

Ocean Air - Plumbing, Heating & Air Conditioning

Ocean Air operates from 66 Old Country Rd, Quogue, NY 11959 and lists a 5-star rating across 82 reviews. Its phone number is (631) 237-3155. The general-contractor listing plus 24/7 availability together suggest readiness for after-hours service calls. The raw rating of 5 sits 0.236 above the national mean of 4.764; with 82 reviews the adjusted score falls only to 4.997, a movement of 0.003. These numbers cannot reveal whether the firm maintains its own service trucks or subcontracts overflow work.

PerfecTemp Heating and Air Conditioning

PerfecTemp Heating and Air Conditioning is located at 63 Clinton St Ste A, Center Moriches, NY 11934 and carries a 5-star rating on 85 reviews. The contact number is (631) 629-4800. Its general-contractor category and lack of published 24/7 status point to standard business-hour operations. The raw 5 exceeds the national mean by 0.236; 85 reviews produce an adjusted score of 4.978, a drop of 0.022. The figures give no indication of typical lead times for non-emergency installs.

Its raw rating of 5 is 0.236 above the mean; 37 reviews move the adjusted score to 4.954, a reduction of 0.046. The data leave open the question of how many technicians are on staff during peak winter weeks.

These counts do not disclose whether the firm performs its own ductwork or relies on separate trades.

These counts cannot indicate how many of the reviews came from heating versus cooling jobs.

Licensing and permits

New York has no state HVAC contractor licensing board. Licensing authority is delegated to individual cities and counties. The New York City Department of Buildings, for example, requires an Oil Burner Equipment Installer license (Class A or B) for oil-fired equipment and may require a High-Pressure Boiler Operating Engineer or Special Rigger license depending on system type. Electric-only central air or heat-pump work carries no dedicated trade license beyond general contractor and permit rules. Insurance requirements also vary by jurisdiction; New York City mandates General Liability, Workers' Compensation and Disability coverage for oil-burner licensees, yet no statewide minimum exists because no statewide license exists. Permits themselves are issued locally and are required in most Suffolk County towns.

Climate demands on equipment

Suffolk County lies in IECC zones 4A-6A with a dominant zone of 5A and a moist regime. Heating degree days total 5,700 while cooling degree days reach only 900, producing a heating-leaning mixed load profile. Winter design temperature is 15 °F and summer design temperature is 91 °F, with humid summers and dry winters. Primary heating fuel is natural gas or fuel oil. Heat pumps are suitable with cold-climate backup. Central air saturation is moderate to high. Peak service season falls in winter. The engineering note highlights a heating-dominant climate statewide, although New York City is milder than upstate zone 6A, and a large steam and hydronic retrofit market exists. Equipment must therefore be sized for the winter peak and often paired with existing hydronic distribution.

Available incentives

The EmPower+ / NY Home Energy Rebates program through NYSERDA is listed as limited availability. Heat-pump rebates reach $8,000 under HEAR and up to $10,000 for income-eligible households under EmPower+. No state tax credit covers heat pumps; the 25 % solar credit capped at $5,000 does not apply. Utility programs under NYS Clean Heat, administered by Con Edison, National Grid, NYSEG, RG&E, Central Hudson, PSEG-LI and LIPA, offer $1,000-$5,000. Participation in the NYS Clean Heat contractor network is mandatory; the rebate is paid through the contractor, so a non-participating installer yields zero incentive. The 25C and 25D federal credits expired at the end of 2025. Only the commercial 48E ITC remains for qualifying systems.

How to choose an installer

Match the firm's review volume to the size of the job, confirm NYS Clean Heat participation before any heat-pump discussion, and verify the exact permit and insurance rules of the town where the work will occur. Request the specific license class required for the equipment being installed and ask which source of cost data the quote reflects.
