Top 7 HVAC companies in Durham, North Carolina

Durham County, North Carolina, lists a population of 321488 and sits in IECC zone 4A with a balanced mixed load profile. Public listing data collected on 2026-08-16 supplies the seven ranked contractors below. The ranking applies a Bayesian adjustment that pulls every raw star rating toward the national mean of 4.764, so a perfect 5.0 earned from a modest number of reviews receives a lower adjusted score. Two cost sources appear for full system work and state licensing details are drawn directly from the North Carolina State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors.

How to choose

Review depth matters because the Bayesian formula moves a rating closer to 4.764 when the count is low. Confirm the contractor holds the correct Heating Group class for the equipment being installed, verify participation in the Duke Energy network when rebates are involved, and ask the local building department about any additional bond or registration required beyond the state license. Installed cost figures and climate data further narrow realistic options for a given home.

The shortlist

Hometown Air, LLC

Hometown Air, LLC operates from 3917 Comfort Ln, Durham, NC 27705 and lists the phone number (919) 568-3212. Its 30 reviews produced a raw rating of 5 that the Bayesian adjustment lowered to 4.922 because the volume remains well short of the counts needed to stand apart from the national mean of 4.764. The firm appears as a general contractor with a public website but no published 24/7 availability. These numbers cannot reveal how the crew performs on high-humidity summer calls or whether change-out times stay within the local permit window.

Durham Mechanical Services, Inc.

Durham Mechanical Services, Inc. is located at 4517 Hillsborough Rd, Durham, NC 27705 and can be reached at (919) 382-6377. Ten reviews at a raw 5 yielded an adjusted score of 4.863 after the same pull toward 4.764. The listing shows a general contractor category plus a public website and standard hours. Review volume alone explains the size of the adjustment; the numbers leave open the question of how the firm handles the 22-degree winter design day when heat-pump demand spikes.

Heating & Cooling

Heating & Cooling is listed at 717 E Maynard Ave, Durham, NC 27704. Its two reviews at a raw 5 produced an adjusted score of 4.779 with no additional ranking signals. The entry shows a general contractor category, no website, and no 24/7 notation. The phone number field is empty in the source data. The limited review count accounts for most of the movement from raw to adjusted; the data set supplies no information on actual job completion times or callback rates.

Heating and Air Conditioning

Heating and Air Conditioning sits at 311 N Lasalle St, Durham, NC 27705 and lists the phone number (919) 823-9084. Fifteen reviews produced a raw 4.5 that adjusted only slightly to 4.676 because the rating already sat below the national mean of 4.764. The firm appears as a general contractor without a website or 24/7 listing. The modest review count still influenced the final placement, yet the numbers give no indication of how the company performs under the county's 1700 cooling degree days.

Scoggins And Co., Inc.

Scoggins And Co., Inc. operates from 918 Pearl St Unit A, Durham, NC 27701 and can be reached at (919) 382-0534. Twelve reviews at a raw 4.3 moved upward to an adjusted 4.671 once pulled toward 4.764. A public website is present and the category is general contractor without 24/7 availability. The adjustment direction and size reflect both the starting rating and the review volume; the figures do not address whether the firm meets the equipment class requirements for larger heat-pump systems.

Shepherd Heating & Air Conditioning

Shepherd Heating & Air Conditioning is located at 1405 Old Oxford Rd, Durham, NC 27704 and lists the phone number (919) 477-5458. Twenty-four reviews at a raw 4.4 adjusted to 4.622, helped slightly by the published 24/7 availability signal. The firm is shown as a general contractor without a website. The review count still produced a noticeable shift toward the national mean; the data leave open how the 24/7 claim translates into actual response on peak summer days.

Durham Heating & Air Conditioning Inc.

Durham Heating & Air Conditioning Inc. is at 700 Foster St, Durham, NC 27701 and can be reached at (984) 252-4275. Twenty-three reviews at a raw 4.4 adjusted to 4.606 with no extra ranking signals. The category is general contractor and hours are standard. Review volume drove the adjustment from raw to final score; the numbers supply no detail on how the firm manages the humid-summer latent load in zone 4A.

Installed costs

Two separate sources supply full-system figures for Durham. One lists a typical installed price of $8,800 inside a range of $7,900 to $9,700. A second 2025 invoiced data set shows an average of $15,997 and an upper quartile of $23,400. Labor is stated at $95 per hour and permit fees range from $100 to $350. The spread between the two sources is itself information for any homeowner comparing bids.

Licensing and permits

Contractor licensing occurs at the state level through the North Carolina State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors. The board issues Heating Group 1 Class I and II, Heating Group 2, and Heating Group 3 Class I and II licenses that are tied to system type and capacity; a separate refrigeration license is handled by another board. No statewide surety bond or general liability minimum is required, though workers compensation insurance is mandatory for firms with three or more employees. Permits for furnace or air conditioner replacement are issued by the local city or county inspections department, and some municipalities add their own bond or registration layer.

Available incentives

Energy Saver NC offers a heat-pump rebate up to $8,000 but remains in limited phased rollout, so availability depends on the specific county. Duke Energy programs provide $300 to $1,500 through ratepayer rebates and require participation in the utility contractor network. No state tax credit exists. The 25C and 25D federal credits expired at the end of 2025, leaving only the commercial 48E incentive for third-party-owned systems that meet the 2026 construction or service deadlines. Homeowners must therefore select installers already inside the Duke network to capture the remaining rebates.

Local climate demands

Durham falls in the dominant IECC zone 4A moist regime with 3300 heating degree days and 1700 cooling degree days. Design temperatures are 22 degrees Fahrenheit in winter and 93 degrees Fahrenheit in summer, with humid summers the norm. The load profile is balanced mixed and the primary heating fuel is electricity, making heat pumps an excellent fit. Equipment must handle both the winter design day and the latent load during peak humidity, so proper sizing calculations remain essential to avoid short-cycling or inadequate dehumidification.

A shortlist built from public listing data is not a review of work performed on any specific job. Homeowners should verify current license status directly with the North Carolina State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors and request references before signing a contract.
