# KING OF SERVICE LLC **Trade:** HVAC / Heating & Cooling · **Address:** 90 Blithewood Ave, Worcester, MA 01604 · **Phone:** (617) 959-6291 · **Website:** http://www.kingofservicellc.com/ · **Languages:** English **Rating: 4.2/5** (medium confidence) — from 17 reviews across 4 sources. 100% of sentiment-scored reviews read net-positive. Last 6 months: 1 reviews, 0 negative. ## The honest read King of Service LLC is a Worcester HVAC contractor serving residential and commercial customers with heating, air-conditioning, heat-pump, installation, maintenance, repair, and 24/7 emergency service. Its website says the company has a factory-authorized premium HVAC brand dealer relationship, geothermal specialization, a NATE-certified technical team, and Local First Business Alliance and Angie's List Super Service Awards affiliations. The site identifies King of Service LLC by name and lists its Worcester address and phone, but does not state a founding date or owner name. Google shows 18 ratings and 17 written reviews, all five-star, dated from September 2025 through July 2026. Customers describe no-heat furnace repair, tankless-water-heater repair, air-conditioning repair, new heating and cooling system installation, and urgent commercial-cooler service. Reviewers repeatedly mention prompt arrival, clear explanations, professional work, reasonable or competitive pricing, and successful repairs; one restaurant owner describes multiple emergency industrial-cooler calls, while another reviewer describes replacement work after a four-level condo’s two central-air units failed during extreme heat. Before booking, confirm the exact equipment scope, installation warranty, emergency-service terms, and any permit or license requirements for the work. The website’s certification and affiliation statements are self-reported, and the review history is concentrated in a relatively recent 2025–2026 window, so ask for current documentation and a written quote. King of Service appears best suited to Worcester-area homeowners and businesses needing HVAC troubleshooting, installation, maintenance, or emergency response, with plumbing-related work mentioned in one customer review rather than established as the primary trade. **Strengths:** - HVAC troubleshooting — detailed reviews describe successful repairs - Emergency response — customers cite rapid help for urgent failures - Clear explanations — reviewers mention knowledgeable, communicative technicians - Fair pricing — multiple customers cite reasonable or competitive rates **Concerns:** - Recent review window — written reviews cluster from September 2025 to July 2026 ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - King of Service LLC presents itself as a Worcester HVAC contractor offering heating, air-conditioning, heat-pump, commercial HVAC, installation, maintenance, repair, and 24/7 emergency services. _(confidence: high)_ - [Official Website](http://www.kingofservicellc.com) — “King of Service LLC presents itself as a Worcester HVAC contractor providing heating, air-conditioning, heat-pump, commercial HVAC, installa…” - The website states factory-authorized premium HVAC brand dealer, geothermal specialist, and NATE-certified technical team claims. _(confidence: medium)_ - [Official Website](http://www.kingofservicellc.com) — “Stated certification/affiliation: Factory-authorized premium HVAC brand dealer” - [Official Website](http://www.kingofservicellc.com) — “Stated certification/affiliation: Geothermal specialist” - [Official Website](http://www.kingofservicellc.com) — “Stated certification/affiliation: NATE-certified technical team” - The website states Local First Business Alliance membership and an Angie's List Super Service Awards recipient affiliation. _(confidence: medium)_ - [Official Website](http://www.kingofservicellc.com) — “Stated certification/affiliation: Local First Business Alliance member” - [Official Website](http://www.kingofservicellc.com) — “Stated certification/affiliation: Angie's List Super Service Awards recipient” - Google displays 5 stars from 18 ratings, with 17 written reviews available in the packet. _(confidence: high)_ - [Google](https://www.google.com/maps/search/?api=1&query=KING%20OF%20SERVICE%20LLC&query_place_id=ChIJR3q6ux5LrYgRKTGfBBptOTs) — “Google: 5★ from 18 ratings” - Reviewers describe prompt, professional HVAC service and clear explanations across furnace, air-conditioning, water-heater, installation, and emergency commercial-cooler work. _(confidence: high)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sCi9DQUlRQUNvZENodHljRjlvT2pGb1lrRTFlbHAzUVd3d2RFbHJOakJSZDNoMVdXYxAB!2m1!1s0x0:0x3b396d1a049f3129!3m1!1s2@1:CAIQACodChtycF9oOjFoYkE1elp3QWwwdElrNjBRd3h1WWc%7C%7C?hl=en) — “5★ We recently called King Of Service as we had problem with no heat.
