Top 7 HVAC companies in Rockingham, New Hampshire

The shortlist

Pilot Plumbing, Heating and Cooling tops the list after Bayesian adjustment and tie-breakers. The remaining six firms follow in order of adjusted rating, with raw scores pulled toward the national mean of 4.764.

Pilot Plumbing, Heating and Cooling

Pilot Plumbing, Heating and Cooling operates from 265 Fremont Rd, Sandown, NH 03873. Its listing shows 58 reviews at a raw 5.0 that Bayesian adjustment lowers to 4.92 because the count is still modest relative to national volume. The firm lists as a plumber and publishes 24/7 availability, both of which supplied the tie-breakers that secured first place. (603) 634-8531 remains the contact number given in the directory. These signals indicate steady work in heating and cooling alongside plumbing, yet the numbers give no indication of actual workmanship quality or callback rates on fuel-oil or propane jobs.

JP HVAC - Heating & Cooling

JP HVAC - Heating & Cooling sits at 3 Kelby Scott Way, Exeter, NH 03833 and records 47 reviews at a raw 5.0 adjusted downward to 4.908. The modest review count produces a 0.092-point pull toward the national mean. The firm lists as a general contractor and maintains a published 24/7 schedule that earned tie-breaker credit. (603) 262-3919 is the listed phone. The combination points to full-time heating and cooling focus, but four dozen reviews still leave room for performance variation not captured in the star rating.

New Age Heating and Air Conditioning

New Age Heating and Air Conditioning works from 14 Cross St, Salem, NH 03079. Twenty-nine reviews at raw 5.0 adjust to 4.88 under the same Bayesian formula. Public website and 24/7 listing supplied the tie-breakers. (603) 571-0183 is the directory number. Category listing as general contractor suggests the firm handles broader residential work, yet the review volume remains too low to confirm consistency across heating-dominant installs.

Courtesy Heating and Cooling

Courtesy Heating and Cooling lists 22 Peabody Dr, Brentwood, NH 03833 with 25 reviews at raw 5.0 adjusted to 4.871. Absence of 24/7 status removed one tie-breaker, placing the firm fourth. (603) 777-7749 is the published contact. The general-contractor category and website presence are the only signals available; the numbers cannot reveal how often the firm performs equipment sizing calculations versus simple change-outs.

Revolution HVAC

Revolution HVAC operates from 92 Center Rd, Weare, NH 03281 and matches Courtesy on 25 reviews at raw 5.0 adjusted to 4.871. Public website supplied the single tie-breaker. (603) 489-2068 is the listed phone. General-contractor status and lack of 24/7 listing explain the position; the data set offers no detail on whether the firm maintains stock of cold-climate heat-pump models suited to zone 6A loads.

Comfort Air Services.

Comfort Air Services. is located at 91 Sandown Rd, Fremont, NH 03044. Four reviews at raw 5.0 adjust to 4.792, the largest downward pull because the sample is smallest. 24/7 availability and website presence earned tie-breaker points that kept it ahead of the final firm. (603) 253-2120 is the directory number. The services category and tiny review count mean the numbers cannot distinguish between occasional service calls and full system replacements.

CAC Mechanical Services Inc

CAC Mechanical Services Inc works from 68 Stiles Rd Ste F, Salem, NH 03079. Fourteen reviews produce a raw 4.1 that Bayesian adjustment raises to 4.553, the only upward correction in the set. Website and 24/7 listing supplied tie-breakers. (603) 893-6618 is the listed contact. The general-contractor category and below-mean raw score indicate the firm carries less review weight than the five-star entries above it.

How to choose

Companies are ranked by a Bayesian-adjusted rating that pulls each star rating toward the national mean of 4.764 until review volume is large enough to stand alone. A 5.0 from four customers therefore sits below a 4.9 from two hundred. Additional tie-breakers reward a public website, HVAC-specialist category listing, and published 24/7 availability. This shortlist is built only from public listing data and the published formula; it does not constitute a review of work performed.

Cost

Modeled typical full-system install cost stands at $10,800, with the documented range running from $9,700 to $11,900. Invoiced averages for 2025 reach $16,421 while the upper quartile hits $23,877. Labor is published at $130 per hour and permit fees fall between $120 and $400. The invoiced average sits well above the modeled typical price, a gap that appears in both cost sources. These figures cover equipment and labor for heating-dominant replacements common in Rockingham County; they do not include electrical upgrades or duct modifications that may arise on older homes.

Climate

Rockingham County falls in IECC zones 5A-6A with zone 6A dominant. Heating degree days reach 6,800 while cooling degree days total only 500, confirming a strongly heating-dominant load profile. Winter design temperature is -3 °F and summer design reaches 89 °F under dry winter humidity conditions. Primary heating fuel remains fuel oil and propane, with central air saturation still low to moderate. The climate therefore demands equipment sized for long heating seasons and cold-climate heat-pump performance with backup heat. High fuel-oil dependence also drives growing mini-split retrofit demand for efficiency upgrades.

Licensing and permits

New Hampshire maintains state-level licensing through the Office of Professional Licensure and Certification Board of Mechanical Safety and Licensing. No general HVAC license exists; the state licenses only Fuel Gas Fitter categories and Mechanical Business Entities. General heating and cooling work without fuel-gas piping is not state-licensed, though a voluntary Oil Heating Technician certification is available. Insurance requirements are not specified at state level. Permits are required under the New Hampshire State Building Code for most HVAC installations and are issued and inspected by local municipal building departments rather than the state.

Incentives

The NH Home Energy Rebates program, funded through DOE-NH, is approved for launch in spring or summer 2026 with heat-pump rebates up to $8,000. NHSaves utility rebates range from $500 to $3,000 and require a participating contractor. No state tax credit applies. Federal 25C and 25D credits expired at the end of 2025, leaving no residential HVAC tax credit in 2026. The 48E commercial credit remains available only for third-party-owned systems meeting construction deadlines. Because New Hampshire issues no general HVAC license, homeowners seeking rebates must verify NATE certification or manufacturer training directly with any installer under consideration.

The shortlist rests on public data available as of August 2026. Homeowners should confirm current credentials and rebate participation before committing to any firm.
