Top 7 HVAC companies in Prince George's, Maryland

Prince George's County, Maryland, holds a population of 909327 and sits in a mixed-humid climate zone. This shortlist ranks seven HVAC firms by Bayesian-adjusted rating drawn solely from public listings collected on 2026-08-16. The method pulls each raw star rating toward the national mean of 4.764 until review volume allows the score to stand alone. A public website, HVAC-specialist listing, and published 24/7 availability supply small tie-breakers. The result is a data-derived ordering, not an assessment of completed work.

The shortlist

Su' Coy Heating, AC & Duct Cleaning

Su' Coy Heating, AC & Duct Cleaning lists 226 reviews at a raw 4.9 stars. Its adjusted score reaches 4.944 after modest upward movement from the 4.764 national mean, aided by the large review count. The firm operates from 100 M St SE #600, Washington, DC 20003 as a general contractor that also publishes 24/7 availability. That combination of signals and review depth places it first. The phone number is (301) 888-0037. These figures say nothing about workmanship quality on any particular job.

Assured Comfort Services, LLC

Assured Comfort Services, LLC records 20 reviews at a perfect 5.0 raw rating. The adjusted score settles at 4.898, pulled downward from the raw figure toward the 4.764 mean because the review count remains modest. It works from 3221 Beverly Dr, Huntingtown, MD 20639 as a general contractor without published 24/7 hours. The phone number is (443) 968-2336. The numbers leave open whether the firm maintains consistent capacity during peak summer weeks.

Nero's Heating and Air

Nero's Heating and Air shows 231 reviews at 4.8 raw stars. Its adjusted score of 4.856 reflects slight downward pull from the raw value toward the national mean, tempered by high review volume and both a website and 24/7 listing. The address is 1712 62nd Ave, Cheverly, MD 20785. The phone number is (202) 750-9543. The data cannot reveal how often the firm turns away work during the humid summer peak.

Aire Serv of Prince Georges County

Aire Serv of Prince Georges County carries 181 reviews at 4.8 raw stars. The adjusted score of 4.855 sits close to the raw rating because the review count limits movement toward the 4.764 mean. It lists as a general contractor from 9701 Apollo Dr Ste 100-16, Largo, MD 20774 and advertises 24/7 service. The phone number is (240) 326-2987. These metrics do not address scheduling lead times once a contract is signed.

Jireh Heating & Cooling

Jireh Heating & Cooling appears with a single review at 5.0 raw stars. Its adjusted score of 4.812 is drawn noticeably toward the 4.764 national mean by the very low review count. The firm operates from 8601 Temple Hill Rd, Temple Hills, MD 20748 as a general contractor without 24/7 publication. The phone number is (240) 831-2713. The sparse data leave open whether the rating will hold after additional jobs are completed.

United Air Temp

United Air Temp lists 153 reviews at 4.7 raw stars. The adjusted score of 4.77 moves upward from the raw figure toward the 4.764 mean, reflecting the moderate review volume. It works from 9634 Marlboro Pike, Upper Marlboro, MD 20772 as a general contractor that also publishes 24/7 availability. The phone number is (410) 424-5935. The numbers cannot indicate how the firm performs on complex ductwork retrofits.

Logan Mechanical LLC

Logan Mechanical LLC records 214 reviews at 4.7 raw stars. Its adjusted score of 4.748 edges upward from the raw rating toward the 4.764 mean, limited by the solid review count. The address is 6014 Sellner Ln, Clinton, MD 20735. It lists as a general contractor without 24/7 hours. The phone number is (240) 899-8305. The figures leave unanswered how quickly the firm can scale during simultaneous heating and cooling calls.

How to choose

State HVACR licensing covers Master HVACR Contractor, Master Restricted Contractor, and Limited Contractor categories. Homeowners should confirm both the HVACR license through the Maryland Board lookup and MHIC registration, because the state Guaranty Fund reimburses losses only from properly registered contractors. Utility rebates further require the installer to belong to the EmPOWER participating-contractor network.

Cost

Installed-cost data show a typical full-system price of $11,200 with a reported range of $10,100 to $12,300. A separate 2025 invoiced average reaches $21,474, and the upper quartile hits $30,000. Labor runs $140 per hour while permit fees range from $150 to $500. The two cost sources diverge, which itself signals that final pricing depends on equipment tier, duct modifications, and whether the project triggers local inspection fees. High-cost-tier status versus national averages appears in both datasets.

Climate

Prince George's County falls in IECC zone 4A with a moist regime. Heating degree days total 4400 while cooling degree days reach 1300, producing a heating-leaning mixed load. Design temperatures are 15 °F in winter and 93 °F in summer, with humid conditions in the cooling season. Equipment must therefore handle both heating and dehumidification without oversizing, because the balanced yet heating-dominant profile rewards accurate Manual J calculations. Heat pumps show very good suitability and central air-conditioning saturation is already high.

Licensing and permits

HVACR licensing is issued at the state level by the Maryland Board of Heating, Ventilation, Air Conditioning and Refrigeration Contractors. Required coverage includes at least $300,000 general liability and $100,000 property damage, for a combined minimum of $400,000. Permits themselves vary by jurisdiction; the Board publishes a county reference list, and residential changeouts need a mechanical permit from the local county or municipal building department. State licensure alone does not satisfy every local rule.

Incentives

Maryland's HERO and HEAR programs remain conditionally approved, with an $8,000 heat-pump rebate planned once the administrator is selected. EmPOWER Maryland utility rebates range from $300 to $1,500 and require an approved contractor. No federal residential tax credit applies in 2026. The combination means homeowners should first confirm the installer participates in both the utility network and the state HVACR registry before discussing any incentive.

Public listing data alone cannot predict on-site performance or long-term reliability for any of the ranked firms.
