Top 7 HVAC companies in Worcester, Massachusetts

Worcester County, Massachusetts lists a population of 830622. Public listing data collected on 2026-08-16 supplies the basis for this ranking of HVAC providers. Companies appear in order of Bayesian-adjusted rating that pulls raw scores toward the national mean of 4.764. The shortlist draws solely from those records and includes address, phone, review count, and listing category for each firm.

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.

Air Care Cooling & Heating LLC

Air Care Cooling & Heating LLC operates from 44 Mower St, Worcester, MA 01602 and lists the category Services. Its six reviews produced a raw rating of 5 that the adjustment process lowered to 4.843 because the national mean sits at 4.764 and modest review volume allows noticeable pull. The firm maintains a public website but does not advertise 24/7 coverage. These figures leave open questions about performance on larger installations or long-term reliability that review counts alone cannot address. Call (774) 535-4750 to discuss project scope.

Redmond HVAC LLC

Redmond HVAC LLC sits at PO Box 2833, Worcester, MA 01613 and appears under General contractor. Three reviews at a raw 5 moved down only slightly to an adjusted 4.825 given the same national mean and limited sample size. The listing includes a public website yet no round-the-clock service. The adjustment distance reflects how few reviews keep the score tethered closer to the mean than larger data sets would allow. Reach the firm at (508) 864-1103.

D & D Heating & Air Conditioning Inc

D & D Heating & Air Conditioning Inc lists 26 Jennings St, Worcester, MA 01604 under General contractor. A single review at raw 5 produced an adjusted score of 4.812, still drawn downward by the national mean because one data point supplies minimal resistance to shrinkage. The company maintains a website but shows no 24/7 listing. Numbers this thin cannot speak to consistency across varied job types or seasonal demand spikes. Contact (508) 753-4328.

Johnstone Supply

Johnstone Supply operates from 4 Quinsigamond Ave, Worcester, MA 01608. Five reviews yielded a raw 4.8 that adjusted upward to 4.809 because the score sat below the national mean of 4.764 and the Bayesian step lifted it. The listing carries a public website and no 24/7 notation. The modest upward correction shows how review volume interacts with distance from the mean. Call (508) 795-7777.

Heating & Air Conditioning

Heating & Air Conditioning lists 96 Vernon St, Worcester, MA 01610 under General contractor. Its three reviews at raw 5 adjusted to 4.785 with no additional signals. The firm shows neither website nor 24/7 availability in the records. The narrow gap to the national mean leaves the adjusted score nearly unchanged from raw. No phone number appears in the public listing.

Done Right Mechanical Services

Done Right Mechanical Services sits at 48 Fox St, Worcester, MA 01604 and lists General contractor. Eight reviews produced a raw 4 that the adjustment raised to 4.663 because the score fell below the national mean and the larger review count limited how far the pull extended. The firm publishes both a website and 24/7 availability, the latter supplying a tie-breaker. These data points still leave performance on complex refrigerant systems unaddressed. Reach them at (508) 963-1761.

All points hvac

All points hvac operates from 648 Southbridge St, Worcester, MA 01610 under General contractor. Eight reviews at a raw 3.3 adjusted upward to 4.516 given the distance below the national mean and the same review volume that caps the Bayesian movement. The listing includes a website plus 24/7 availability. The adjustment distance here exceeds that of higher-rated peers because the starting raw score sat farther from the mean. Call (508) 459-6880.

How to choose

Compare review volume first, then note whether the firm appears under Services or General contractor. Check published availability when emergency response matters. Confirm the adjusted score accounts for the national mean pull rather than relying on raw stars alone.

Cost

Installed costs vary by source. One dataset places typical full-system work between $11,300 and $13,800 while 2025 invoiced averages reached $23,586 with an upper quartile of $33,537. Labor rates sit at $160 per hour and permit fees range from $200 to $650. The two cost sources disagree on central tendency, which itself signals market variability in Worcester County.

Climate

Worcester County falls in IECC zones 5A-6A with heating degree days at 5700 and cooling degree days at 700. Winter design temperature is 9 °F and summer design reaches 90 °F under humid summer conditions. The load profile is heating-leaning, so equipment must handle long heating seasons and cold-climate heat pumps often require backup. Peak service demand occurs in winter.

Licensing and permits

Massachusetts issues trade licenses at the state level through the Division of Occupational Licensure, the Board of Pipefitters, Refrigeration Technicians, and Sprinkler Fitters, the Board of State Examiners of Plumbers and Gas Fitters, and the Board of Examiners of Sheet Metal Workers. No single HVAC contractor license exists; refrigeration licensing applies only above 10 tons, while gas, electrical, and sheet metal work each require separate state credentials. Insurance requirements are set locally for permits, and building permits themselves come from the city or town under 780 CMR.

Incentives

Mass Save delivers the primary state rebates, with heat pump incentives up to $8,000 that can stack with utility offerings. The 25C and 25D federal credits expired after 2025, leaving only commercial 48E pathways. Municipal light customers in roughly 40 communities do not pay into Mass Save and therefore receive none of its rebates. A pre-install energy assessment is required for the largest incentives, so quotes should reflect that step.
