Top 7 HVAC companies in Albany, New York

Public records supplied the seven companies ranked below for Albany County. The Bayesian adjustment pulls each raw star rating toward the national mean of 4.764, so firms with fewer reviews move closer to that mean while those with more reviews retain more of their original score. Additional small credits apply for a public website or specialist listing.

Cost of HVAC work in Albany County

Installed costs for a complete residential system sit at a published typical figure of $12,450. The supplied range runs from $11,200 to $13,700. A separate 2025 invoice dataset reports an average of $15,721 with the upper quartile reaching $22,000. Both sources appear in the same data set and the gap between them is therefore retained as information. Labor is listed at $160 per hour. Permit fees fall between $200 and $700. The two cost sources disagree on the central tendency, with the higher invoice average likely reflecting larger or more complex jobs. Homeowners comparing quotes should therefore request line-item breakdowns that isolate equipment, labor, and permit charges.

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.

Johnstone Supply

Johnstone Supply operates from 63 Railroad Ave, Albany, NY 12205 and lists the phone number (518) 347-9700. Its six reviews produced a raw rating of 5.0 that the ranking formula adjusted downward to 4.843, still above the 4.764 national mean, because the modest review count limits how far the score can deviate. The presence of a public website supplied the final tie-breaker margin that placed it first. The listing category field is blank, which leaves open whether the firm functions primarily as a wholesaler or installer. These numbers cannot reveal whether the six reviewers all received the same type of service or whether any post-installation issues arose later.

CTC MECHANICAL LLC.

CTC MECHANICAL LLC. lists its address as 911 Central Ave, Albany, NY 12206 with phone (518) 207-8405. Three reviews at a raw 5.0 adjusted to 4.825. The pull toward 4.764 is slightly stronger than for the leader because the review count is lower, yet the public website still supplied enough tie-breaker weight to keep it ahead of the next firm. The general-contractor category indicates the company handles a broader range of building trades. The limited sample size means the numbers cannot distinguish between routine maintenance calls and full system replacements.

R.E. Michel Company

R.E. Michel Company is located at 1 Marshall Pl, Albany, NY 12207 and can be reached at (518) 465-2477. Its three reviews also produced a raw 5.0, adjusted to 4.785 with no website present to add extra points. The wholesaler category suggests the firm may focus on parts supply rather than direct installation. Because the review count matches the firm immediately above it, the absence of a website accounts for the lower position. The data leave open whether customers who left the three reviews purchased equipment only or received installation support.

Colonie Mechanical Contractors, Inc.

Colonie Mechanical Contractors, Inc. sits at 17 Railroad Ave, Albany, NY 12205 with phone (518) 459-5753. Four reviews at a raw 4.0 adjusted upward to 4.714, moving closer to the 4.764 mean because the small sample size exerts stronger shrinkage. The general-contractor listing and public website supplied the tie-breaker margin. The rating sits below the three higher-ranked firms, yet the adjustment shows how limited review volume compresses differences. These figures cannot indicate whether the four reviews covered comparable job scopes.

The Walters Company

The Walters Company operates from 9 Petra Ln, Albany, NY 12205 and lists (518) 452-4292. Six reviews at a raw 4.0 adjusted to 4.677, again pulled toward 4.764. The public website added the margin that kept it above the next entry despite the identical review count to Johnstone Supply. The general-contractor category appears again. The numbers leave unclear whether the six reviewers experienced similar response times or equipment outcomes.

ESCO, Inc. - Heating & Cooling

ESCO, Inc. - Heating & Cooling is at 12 Burdick Dr, Albany, NY 12205 with phone (518) 482-0375. Six reviews produced a raw 3.8 that adjusted upward to 4.643, closing much of the gap to the 4.764 mean because of the modest review volume. The public website supplied the final ordering point. The general-contractor designation is consistent with several peers. The figures cannot disclose whether the lower raw rating reflected isolated service issues or simply a different customer mix.

Empire Air Specialties Inc

Empire Air Specialties Inc lists 40 Kraft Ave, Albany, NY 12205 and the number (518) 689-4440. Five reviews at a raw 3.4 adjusted to 4.569 with no website to alter the placement. The general-contractor category matches most of the list. The larger distance from the mean reflects both the lower raw score and the still-small review count. These numbers cannot show whether the five reviews captured typical winter service calls or other work types.

Licensing and permits

New York maintains no statewide HVAC contractor licensing board. The state has delegated authority to individual cities and counties, so Albany County follows its own mechanical permit process rather than a uniform state class. No statewide insurance minimum exists for general HVAC work because no statewide license exists. Oil-fired equipment in some jurisdictions may trigger additional requirements such as a DOB Oil Burner Equipment Installer license, but that rule is city-specific and does not apply uniformly upstate. Permits themselves are issued locally and typically accompany any furnace or air-conditioner replacement. Homeowners should contact the Albany County building department directly to confirm current mechanical permit rules and any insurance documentation the county requests at the time of application.

Climate demands on equipment

Albany County falls in IECC zones 4A-6A with zone 5A dominant. The heating load reaches 5700 degree days while cooling totals only 900, confirming a heating-leaning mixed profile. Winter design temperature is 15 °F and summer design reaches 91 °F with humid summers and dry winters. Primary heating fuels are natural gas and fuel oil. Heat-pump suitability is listed as good only with cold-climate backup. Central air saturation is moderate to high. Peak service demand occurs in winter. The engineering note highlights a large existing steam and hydronic retrofit market. Equipment therefore must be sized for extended heating seasons and must accommodate legacy distribution systems rather than simple forced-air replacements.

Available incentives

NYS Clean Heat and EmPower+ / NY Home Energy Rebates remain the active state programs, though availability is described as 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 and carries a $5,000 cap; it does not cover heat pumps. Utility rebates range from $1,000 to $5,000 through major providers including National Grid. Participation in the NYS Clean Heat contractor network is mandatory because the rebate is paid through the contractor. The 2026 federal position shows both 25C and 25D credits expired at the end of 2025, leaving no residential federal HVAC tax credit. Only commercial or third-party-owned systems retain the 48E ITC. Homeowners must therefore select an installer already inside the NYS Clean Heat network to access any state incentive.

How to choose an installer

Confirm NYS Clean Heat participation first, since non-network installers cannot deliver the rebate regardless of equipment. Request the local mechanical permit number and verify that the firm can handle the specific fuel type and distribution system present in the home. Compare the line-item costs against the published range of $11,200-$13,700 and the higher invoice average of $15,721. Ask for the exact model numbers to ensure they qualify for any remaining EmPower+ incentives. Finally, contact Albany County directly to confirm current permit and insurance documentation requirements before signing any agreement.
